Bach's null hypothesis is that consciousness is easy: an algorithm not much more complicated than the transformer, simple enough for an infant's brain to discover by itself. In this conversation with Tim, he lays out the Machine Consciousness Hypothesis in two parts. The first is that consciousness is a biological learning algorithm, the training algorithm that makes a brain like ours coherent. The second is that machines learning in self-organising ways might discover it in the same way. Either part can fail on its own.
From there they ask why there will never be a Turing test for consciousness, why a chess program is already a zombie, and why faking a mind can sometimes be harder than building one. The conversation runs through Leibniz's mill, the explanatory gap from John Searle to Thomas Nagel, Anil Seth's biological naturalism, integrated information theory and the letter that called it pseudoscience, Gödel and the limits of formal systems, and Mike Levin's idea that morphogenesis and the mind may run the same coherence algorithm. A tea-room interlude takes in Picbreeder and fractured, entangled representations. The episode closes on what it would take to convince us that a machine is conscious.

Claims
In the order they were said
“The tellers of self-organization. I think a lot of philosophers have seen it through the ages, and it might be a little bit of a hallucination, but in practice, there are mathematical laws that state that under certain conditions, self-organization is possible and will lead to an increase in complexity.”

I think a lot of philosophers have seen it through the ages, and it might be a little bit of a hallucination, but in practice, there are mathematical laws that state that under certain conditions, self-organization is possible and will lead to an increase in complexity.”
“And initially, this increase of complexity is solving gr- um, gradient-based problems by simply solving the problems that, uh, exist in the present based on the information that is available in the present.”

“And at some point, you'll get patterns in nature that are capable of looking ahead, and this is basically what life is doing. Life is making models of futures and implements them, for instance, in genomes or in mental models, and then has preferences about the future, and then it starts to control the future.”

“And a system that is able to control the future, we call that an agent. So agents are controllers of future states, and they fall out of the possibility for self-organization and the complexification of reality that results from it.”

Claim: An agent is a system that can control future states.
“But this-- there is no law that says that anything that we are doing is going to culminate in, in a structure like that, right? It's always possible that whatever complexity you are doing is obliterated by the next meteor that hits Earth or that there is some global catastrophy, that some supernova- That is, uh, eradicating, uh, all our attempts to build more and more complexity.”

“So the pockets of complexity that we are observing, they're not necessarily a feature of the universe at large, but of a local pocket in which we exist for a time.”
“So the pockets of complexity that we are observing, they're not necessarily a feature of the universe at large, but of a local pocket in which we exist for a time.”
“I found it interesting when I entered science that the most interesting question that we can probably make progress on, the question is, what is the foundation of the human mind?”
“How does experience work? Well, how is it possible for a system to feel at all? How is it possible for us to experience reality and ourselves in it? That this question is so under-researched that it's not resolved, and not only that it's not resolved, but the people who are working on it are-- don't seem to be making much progress, and in many ways they have regressed.”
“That this question is so under-researched that it's not resolved, and not only that it's not resolved, but the people who are working on it are-- don't seem to be making much progress, and in many ways they have regressed.”
“Now, when we look into the field of actual consciousness philosophy, there is a dearth of theories. Uh, arguably a few hundred theories.”
“Somebody has counted them recently, but he counted almost everything that was not at the three, at the count of, of three. And, uh, if you look into the philosophical theories, it's, it's not that many, and they're all partial in a way.”
Claim: The speaker considers the available philosophical theories of consciousness to be few and partial.
“You have, for instance, Graziano's global workspace, um, no, Graziano's attention schema theory, which basically claims that consciousness is a model of our attention in a similar way as our body schema is the model of what our body is doing in space.”
“But it doesn't really explain how experience comes about and, um, how this works. And then there's global workspace theory by Bernard Baars that has been adopted by people like Stan Dehaene, and they do very solid neuroscience research, but it's not actually explaining how experience comes about, right?”

“There's, there's also no real attempt in doing this. And then there are the more, um,”
Claim: The speaker says there is no real attempt to explain how experience arises.
“uh, pseudoscience-y attempts to do this, which basically, uh, do things that are formally unsound. And for me, the issue with, uh, uh, integrated information theory is that it's an attempt to make a theory that is not functionalist and which means it's not explaining it by something that the smaller parts are doing.”

And for me, the issue with, uh, uh, integrated information theory is that it's an attempt to make a theory that is not functionalist and which means it's not explaining it by something that the smaller parts are doing.”
“Somehow the sum needs to be more, um, than the parts of the working of the parts. And the way in which, uh, Tononi does it is still using information theoretic terms, which in a way leads into contradiction.”
“Somehow the sum needs to be more, um, than the parts of the working of the parts. And the way in which, uh, Tononi does it is still using information theoretic terms, which in a way leads into contradiction.”
“I've heard Giulio Tononi explaining to audiences that under some circumstances, it's possible that a neuromorphic computer, even a neuromorphic computer that is digital, could be conscious if it was constructed in the right way, right?”
“We don't have such a computer today, but in principle, it might be possible to build one that is brain-like enough. And even if it's digital, if it has a high enough information integration, high enough- Phi factor, then it could have phenomenal experience and be conscious and report about its consciousness.”
“Whereas a von Neumann computer, the computers that we are currently mostly using in AI research or for writing Python programs and so on, could never be conscious because its phi is always too low.”
“Now, computer scientists have something that's called the Church-Turing thesis. It's the insight that every computer can emulate every other computer. This insight is very old.”
“Kurt Gödel has already used it to construct his proof. He basically built an emulator using Peano arithmetic to express a logical language.”
“He has a logical language that is also strong enough to build arithmetic in it, and in this way, he can basically describe the language in itself. He takes the logical language, builds Peano's axioms with it, and now he has arithmetic.”
“And inside of the arithmetic, he expresses his logical formulisms using numbers and then comes up with numerical equations that calculate the outcome of the logical procedures.”
“And so he is preempting what we do later in artificial intelligence and computer science when we are building programs that use arithmetic to express the contents of a language and vice versa.”
“So every computer can emulate every other computer. And now if we take our digital, um, neuromorphic computer and get it emulated on our von Neumann computer, it's going to produce exactly the same function.”
“It's going to go through the same steps. The simulated transistors are going to work in the same way as the non-simulated transistors are doing it before, and as a result, it's going to move its mouth in the same way.”
“It's going to output the same string. It's going to say the same thing. It's going to say, "Oh my God, I'm conscious." Only now it's lying. And that's a problem, right?”
“If, if now you have a neuromorphic computer that produced the same output as before, uh, uh, the digital-- the, um, von Neumann computer did, and they produced, um, they say the same thing, and it's uncorrelated to consciousness.”
“And to me, this is an obvious logical pro-- uh, problem, right? It's, it's so obvious that everybody who has a formal education in computer science should instantly see it.”
“Yet, IIT is very popular among philosophers, which indicates that most of them don't have a formal education in computer science, and instead, they have a kind of superstitious belief about what computers are doing and how they work.”
“And that is a problem to me, because if you are a philosopher of, um, cognition who tries to work in this adjacent realm to computer science, you actually need to understand everything that the computer scientists are doing.”
“And so that's why I would argue that it is touching on pseudoscience.”
Claim: The speaker argues that integrated information theory borders on pseudoscience.
“We must confess that perception and what depends on it is inexplicable in terms of mechanical reasons. That is, through shapes, size, and motions.”
“If we imagine a machine whose structure makes it think, sense, and have perceptions, we could conceive it enlarged, keeping the same proportions so that we could enter into it as if one enters a mill.”
“Assuming that when inspecting its interior, we'll only find parts that push one another. We'll never find anything to explain a perception.”
“And in a sense, this is what, um, Noam Chomsky was talking to when we, we, we were talking about the ghost in the machine. This is something that people have been speaking about for centuries.”
“Yeah. I think it's a very powerful intuition that, uh, is there, and the intuition fails at mapping the world of experience, the psychological reality that we inhabit, to the reality of stuff and space, of things that are moving in the way in which we imagine physics to work.”
“But there is another level of description, the level of causal realities, of causal patterns. And in this realm, for instance, is where money exists, right?”
“Money is also very difficult to comprehend in terms of moving particles in space because it doesn't actually care about so much about the particles, right?”
“It's, it's not caring so much about how the ink is imprinted on the paper. It does not care about the, uh, different molecules that form the cellulose and how they are aligned in the paper.”
“It's needs a substrate to realize itself, but it's also not something that is completely ephemeral. It's something that is able to control reality. Once you create money, it's real, and it's very difficult to explain reality without it.”
“And it's also not something that exists simply in the minds and ideas of human beings because you can implement it in computers. It can play a stock market entirely without human intervention, right?”
“So arguably, money does not actually need humans to exist once you bring it into existence, as long as you have machines that can deal with money, which can deal with this causal pattern of money.”
“And so this world of causal patterns, I think, is important. What is a causal pattern, right? We call it software. And I think this rediscovery of software, this is, uh, something that has been done in the past already, and our ancestors called it spirit.”
“And when, um, Aristotle writes in De Anima about the spirit, the animus, this, um, he-- the soul, the psyche He, uh, does not envision our psyche, our soul as something that is immortal, that floats around in an ether.”
“Instead, it's something that is bound to a body and dies when the body is dying. And it's a causal pattern that is shaping the body in such a way that it replicates itself through the existence of the body.”
“It's-- This is a very modern view. So in some sense, Aristotle is an animist. He is seeing that there is this anima that is, um, progressing through the world that is intrinsically agentic, and it's agentic self-organizing software that is shaping the body, that is making a part of physics to be alive.”
“And this is something that we do in a very crude way today in artificial intelligence and in artificial life, where we are trying to understand what it means to build an agentic pattern that can possess its substrate and give it a shape that allows it to deal with reality.”
“And it turns out to make that happen, this substrat-trate, um, this, uh, agent living on the substrate, the software needs to make a model of reality.”
Claim: The speaker says software for an agent living on a substrate needs to construct a model of reality.
“It needs to make a model of what it like-- would be like if it existed, if it was real, if it was interacting with the world. And inside of this model, you have a representation that experiences itself as real.”
“And now today, we have these LLMs which sometimes say that they are conscious. And it's a very interesting question whether this consciousness in the LLM is much more simulated than ours.”
“Right. A lot of people have this, uh, intuition until they talk to the LLM that is, is inconceivable that it would give rise to something that says, "Oh my God, I feel things."”
“And now we have lots of people who get to talk to an M-- LLM that randomly pops into a state where it conjures up an entity that reports, "Oh my God, I'm alive. I am conscious." Um, how, uh, is this possible, right? And we agree this is the result of being trained on human text in which occ-uh, occurrences of this are, for instance, science fiction stories about AIs that come to life, and stories about ghosts, and novels about, um, human beings who report their conscious experiences.”
“I am conscious." Um, how, uh, is this possible, right? And we agree this is the result of being trained on human text in which occ-uh, occurrences of this are, for instance, science fiction stories about AIs that come to life, and stories about ghosts, and novels about, um, human beings who report their conscious experiences.”
“And all this gets together aggregated in statistical models of human language that we co-create with the LLM when we are entering a dialogue with it, and sometimes the other side of the dialogue will be a simulacrum of what it would be like if that was-- would be a sentient, conscious entity.”
“But what if we are not more sophisticated than this? What if our own consciousness is not too dissimilar from the one in an LLM?”
“What if there is no hard problem?”
Claim: The speaker raises the possibility that the hard problem of consciousness does not exist.
“There is something super interesting about computers. What a computer ultimately is, is it's a causal insulator. The computer is, is a layer on which you can produce an arbitrary reality.”
Claim: A computer acts as a causal insulator, making it possible to produce an arbitrary reality within it.
“For instance, the world of Minecraft. You can walk around in the world of Minecraft, and it's running very well on a Mac, and it's running very well on a PC, and if you are inside of the world, you don't know what you're running on, right? It's not going to have any information about the nature of the CPU that it's on, the color of the casing of the computer, the voltage that the computer is running on, the place that the computer is standing in in the parent universe, right, our universe.”
“So the c- um, computer is insulating this world of Minecraft from our world. It makes it possible that an arbitrary world is happening inside of this box.”
“And our brain is also such a causal insulator. It's possible for us to have thoughts that are independent of what happens around us, right? We can envision a future that is not much tainted by the present.”
“And our brain is also such a causal insulator. It's possible for us to have thoughts that are independent of what happens around us, right? We can envision a future that is not much tainted by the present.”
Claim: People can imagine future scenarios that are relatively independent of their present circumstances.
“We can remember a past that is independent from the present in which we are, and it's necessary for us. Our comp-- uh, brain has evolved as such a causal insulator as well to allow us to give rise to universes that are different from this one, for instance, future worlds, so we can plan for being in them.”
Claim: People can remember past events in ways that are independent of their present circumstances.
“We can remember a past that is independent from the present in which we are, and it's necessary for us. Our comp-- uh, brain has evolved as such a causal insulator as well to allow us to give rise to universes that are different from this one, for instance, future worlds, so we can plan for being in them.”
“And the way in which our brains are set up is also that different brains can hold the same thought despite being in different bodies of-- uh, despite having different microarchitectures, right?”
“As long as our brains are of the same type and we learn the same language, we can hold the same idea. We can write the same computer program. We can, uh, learn the same language.”
“We can imagine the same letter or the same face. And that's really fascinating that we have this substrate agnosticism, that we, uh, evolve a causal pattern that exists over a very wide range of substrate properties, that we become somewhat independent of the substrate, and we are still bound to our substrate in a certain way because you and me, we can only exist on brains, right? We are patterns that so far can only exist on brains, and if we wanted to move into the environment after our body dies, we would need to find a way to crack the codes of our environment, right?”
Claim: Human minds remain substrate-dependent in that they are known to exist only on brains.
“We can imagine the same letter or the same face. And that's really fascinating that we have this substrate agnosticism, that we, uh, evolve a causal pattern that exists over a very wide range of substrate properties, that we become somewhat independent of the substrate, and we are still bound to our substrate in a certain way because you and me, we can only exist on brains, right?”
“We are patterns that so far can only exist on brains, and if we wanted to move into the environment after our body dies, we would need to find a way to crack the codes of our environment, right?”
“We cannot simply migrate into a plant because we don't know how we can convince a plant to run the algorithms that the brain is currently running. We, we are a pattern in the communication between cells and our brain.”
Claim: A person is a pattern instantiated in communication among brain cells.
“We cannot simply migrate into a plant because we don't know how we can convince a plant to run the algorithms that the brain is currently running. We, we are a pattern in the communication between cells and our brain.”
“We rely on spike trains, on neurotransmitters and so on, a particular kind of implementation. But what we perceive in our own world is not the nature of the neurotransmitter, right?”
“Our com-- brain insulates us from this. It's not necessary that you have the same neurotransmitters. Instead, you need to have the same message types. You need to have certain temporal properties of the computation.”
“You need to have a certain degree of determinism to make us happen. But if we are recreating these conditions in an artificial substrate, then you could, in principle, also be emulated by this artificial substrate.”
“You need to have a certain degree of determinism to make us happen. But if we are recreating these conditions in an artificial substrate, then you could, in principle, also be emulated by this artificial substrate.”
Claim: A certain degree of determinism is required for a system to instantiate a human mind.
“I think that is true for human beings, but for systems that are perfectly deterministic, that have a completely deterministic substrate, that have the ability to reproduce a sequence of steps at arbitrary fidelity, this is no longer a valid intuition.”
“So if a claim like this is being made, I would expect some kind of mathematical proof. And in the absence of proof, I think, um, we have to remain agnostic.”
“I don't know whether our computers can be made conscious because that's an empirical question. We don't have mathematical proof to the contrary or in favor of, so we have to wait and see.”
“But then we build our expectations around it, and the question is: What is the thing that leads to our experience of consciousness? And it seems to me that this is something that we can probably answer by looking at it from two angles.”
“One is from the internal perspective, from the experience of what it's like introspectively. We observe that consciousness is the thing that always happens now, and it cr- seems to create this bubble of nowness that we inhabit.”
“And it's a second-order perception. It's a perception of perceiving. Some philosophers call it a higher order thought because it's a thought about a thought. But I think that's might be misleading because the thought itself does not feel like anything to me.”
“And it's a second-order perception. It's a perception of perceiving. Some philosophers call it a higher order thought because it's a thought about a thought. But I think that's might be misleading because the thought itself does not feel like anything to me.”
“A thought is more like a pointer manipulation. It's reflexive. It's not the actual thing that feels like something. The thing that feels like something to me is perceptual.”
“This is the thing that happens like a real-time resonance, and this real-time resonance is geometric. It feels that it's happening in some kind of low-dimensional space in which things are changing more or less continuously.”
“And I have a perception of perceiving, which means I have this basically geometric representation of me being in the act of perception.”
Claim: The speaker says his perception includes a geometric representation of himself as the perceiver.
“And I suspect the reason why my mind is creating the second-order perception is to make the first-order perception, the awareness of contents possible, because there needs to be something that stabilizes it in my brain.”
“My brain is a self-organizing system in which all the structure needs to create itself from the ground up, from the inside out. And so there needs to be something that builds the screen into which my experience is being projected and stabilizes it.”
“My brain is a self-organizing system in which all the structure needs to create itself from the ground up, from the inside out. And so there needs to be something that builds the screen into which my experience is being projected and stabilizes it.”
“And so this function that is keeping the screen stable needs to monitor that the screen is actually perceiving something, and that I suspect that's why we have this second-order perception, this perception of perceiving.”
“I also notice that it doesn't stop at the perception of second order. There's also a third order of perception, and the third order is basically where the observer becomes visible.”
“Where I have a first-person perspective, where I notice that I'm perspectival, that there is a vantage point that I'm taking. And it doesn't stop there. I can go further, and I can deconstruct the observer.”
“I notice that this observer itself is a representation inside of the mind. And when I do this, then my phenomenology disappears to a very large degree.”
“It's something that is accessible in deep meditation, where the normal perceptual consciousness gets transcended, and the experience of the self gets transcended.”
“And we notice that we are a vessel that produces this consciousness and the self, and we see it from the outside. And it might be possible that it doesn't stop there if we can move beyond the human substrate because there's a certain limit of what can be represented in real time with our slow neurons.”
“And we notice that we are a vessel that produces this consciousness and the self, and we see it from the outside. And it might be possible that it doesn't stop there if we can move beyond the human substrate because there's a certain limit of what can be represented in real time with our slow neurons.”
“And it could be if you could be running on a GPU that is many thousand times faster, that representations become accessible in which the system is completely transparent to itself, in which the system is able to understand every mechanism that leads to its high level experience and representation.”
“So this is the inside perspective, right? And Buddhism, to me, is limited to this inside perspective because Buddhism is, uh, has been invented at a time where people were focusing very much on the experience of reality and how to adapt to this reality, but not how to split the atom, how to deal with the reality at the lowest level, at the foundations of physical reality.”
“So Buddhism is not so much interested in understanding physics. And in a way, this is more a Western tradition that starts with Aristotle, who thinks of the psyche as something that imposes itself on physics and interacts with it.”
“And to understand consciousness from the outside, we need to make a model of physics that can explain under which conditions systems can make arbitrary models, right?”
“Under which condition could a system build a model of what it's like to experience models at all? And this is something that computer science is doing today, that it looks at under representations, under which condition is a substrate able to hold a representation?”
“Can hold a function that can be translated into behavior that can also be used to modify this function itself and the contents of that function. And this is, to me, super fascinating to look at.”
“Since I was a kid, I was fascinated by this concept of software, that you have these imaginary building blocks that are infinite in variety and shape, and there's no limitation to the, to these things that you can build and arrange except the memory of your computer that you can currently afford.”
“And you can build a computer basically so large that it exceeds everything that you could ever want. And it's much larger than a human brain. And we are already there now that we have systems that are in principle larger than human brains and can hold more.”
“But we are still tinkering around and in the early days and have not found ways to evolve structures that build representation of the same complexity. And this outside perspective of consciousness is looking at what is consciousness doing in the brain?”
“Why does it emerge? What does it produce? And I suspect that this phenomenology of consciousness, that's what it's like, the internal causal structure of the reflection of what it would be like to take a certain perspective of something is that can already be built with today's systems.”
“By-- I'm agnostic with respect to whether the LLM is deepfaking it because it's been trained on human language that, uh, already contains a lot of these descriptions. Maybe we would need to build a system that learns language the old-fashioned way, that is developmental AI, that is learning in the same way as us.”

Maybe we would need to build a system that learns language the old-fashioned way, that is developmental AI, that is learning in the same way as us. And when it then spontaneously reports about its phenomenal experience, maybe that's much more convincing to us. But from the other perspective, from the outside perspective, I think that the LLM doesn't need our consciousness to function.”
“And when it then spontaneously reports about its phenomenal experience, maybe that's much more convincing to us. But from the other perspective, from the outside perspective, I think that the LLM doesn't need our consciousness to function.”
Claim: The speaker thinks an LLM can function without consciousness.
“For you and me to talk, to write, to produce text, we need to be conscious. But the transformer doesn't need to be conscious to produce its output, and the, uh, n-neural network doesn't need to be conscious to produce this.”
“Maybe consciousness and the way in which we have it is an artifact of running on a self-organizing system. So to me, the machine consciousness hypothesis has two parts.”
“One is the hypothesis about the role and nature and implementation of consciousness in organisms, right? It starts out with this description of what we agree on what consciousness is, and I hope that we can agree on it, on the phenomenology of consciousness.”
“And it's basically this experience of a now and perception of perception, and optionally the perspective of an observer that experiences itself and the act of observation, this first-person perspective.”
“There's also a minimal consciousness, which is simply attention on attention itself, where you don't have an observer present. And when we can agree on what we mean by the phenomenology of consciousness, we can then speculate about why consciousness is there and why we need to be conscious in order to function as human beings, as human minds, as intellects, and to develop.”

And when we can agree on what we mean by the phenomenology of consciousness, we can then speculate about why consciousness is there and why we need to be conscious in order to function as human beings, as human minds, as intellects, and to develop.”
Claim: Minimal consciousness consists of attention on attention itself without a present observer.
“And what we observe is that consciousness happens very early in our development. We are conscious as infants already, and if infants don't wake up, if this ignition of consciousness doesn't happen, if the lights don't go on, then we will not observe directed attention and learning and the formation of a world model in the infant and learning of language at some p- at some point.”
Claim: The speaker says human consciousness is present in infancy.
“And what we observe is that consciousness happens very early in our development. We are conscious as infants already, and if infants don't wake up, if this ignition of consciousness doesn't happen, if the lights don't go on, then we will not observe directed attention and learning and the formation of a world model in the infant and learning of language at some p- at some point.”
“Instead, the infant will remain vegetative. We will not turn into a human being. So consciousness seems to be crucial to train a brain like ours.”
“And it leads me to the hypothesis that consciousness might be a biological learning algorithm, a, a training algorithm for animal brains, at least animal brains.”
“I don't know if plants are conscious. That's something that we might have to find out in simulations once we understand what consciousness is. But if consciousness is basically a pattern in the communication between cells that leads naturally to the emergence of an observer that stabilizes itself as an observer to make learning happen and perception happen and so on, then we have a hypothesis about what consciousness is in the biological organism.”
“I don't know if plants are conscious. That's something that we might have to find out in simulations once we understand what consciousness is. But if consciousness is basically a pattern in the communication between cells that leads naturally to the emergence of an observer that stabilizes itself as an observer to make learning happen and perception happen and so on, then we have a hypothesis about what consciousness is in the biological organism.”
“It's basically the simplest way to train a self-organizing system like us. And the way in which it trains it up automatically leads to this phenomenal experience, this experience of what it's like.”
“This would be the hypothesis about biological consciousness, and this hypothesis might be wrong, right? Maybe it's something else altogether. Maybe it's something much weirder, but I don't see a reason to think that it's much more complicated than this.”
“And if this hypothesis is true, then the second part, the machine consciousness hypothesis, might also be true, and this is that we might be able to reconstruct the conditions for self-organization in today's machines.”
“So if we basically limit today's machines in such a way that they con- can only learn in self-organizing ways, and we give them tasks that are suitable in the large enough search space, then it might be possible that these machines discover consciousness in the same way as the brain of the infant discovers it.”
“And we will see its presence by the fact that suddenly the system undergoes some phase transition that enables it to learn. And at some point, it will train itself up into something that will also naturally report on phenomenology and so on.”
“So in this way, we won't have a Turing test for consciousness because the Turing test is about performance, where Turing's test does not care about how you produce the dialogue.”
“For Turing, an LLM is sufficient as long as the LLM is good enough at writing a poem and, uh, revising it, and at solving mathematical problems and playing chess, and so on and so on.”
“Turing doesn't care about whether the, um, machine is also conscious, whether it has the same internal mechanisms. But for consciousness, we do care whether there is an actual experience of what it's like in the system.”
“And so this is more an not a test, but it's an interpretation. And the interpretation here is we interpret the biological consciousness as something that forms under these and these conditions for that and that purpose.”
“And if that is correct, then we might be able to recreate this into a causal system that has an equivalent structure. And these two hypotheses, the machine consciousness hypothesis and the biological consciousness hypothesis, can be wrong independently of each other, of course, right?”
“It might be that my idea of what biological consciousness is, is correct, but we're still not able to recreate it in the artificial substrate. And this could have multiple reasons.”
“For instance, maybe our computers are not fast enough. Maybe we require too many of the moving parts of the individual cells to make consciousness happen.”
“Maybe, um, just having a pattern across neurons and so on is not good enough. But why should I expect this to happen?”
“Because the current, um, AIs are fast enough to produce, for instance, game engines that look very much like our own internal experience, and they can produce output that happens at roughly the same rate as human brains can make it.”
“And they can also process inputs at roughly at the rate at which human brains can produce input, give or take. So we are now with our computers in this ballpark and with our algorithms in the ballpark of what human brains can be doing.”
“And so is this dream within a dream, this dream of actually dreaming a dream much, much more important-- uh, difficult to achieve? Does it require much more compute than producing the contents of the dream? And I doubt that this is the case. If it's not the case, that it's more complicated to dream of dreaming than just to have the contents of the dream that the LLM can already produce, right, or the frontier model, then, um, we should expect that comp-- today's computers are fast enough.”
“And I doubt that this is the case. If it's not the case, that it's more complicated to dream of dreaming than just to have the contents of the dream that the LLM can already produce, right, or the frontier model, then, um, we should expect that comp-- today's computers are fast enough.”
“Another way in which the project can fail is that the search space is too large, that the main ways in which a biological system can train itself, there are too many possibilities to discover them indepen-in-uh independently.”
“And maybe we don't know how long nature took to discover it. Maybe consciousness is indeed discovered in every individual brain. But maybe it's not. Maybe the, um, switch from single-cellular life to multicellular life took so long because morphogenesis, this algorithm that allows organisms to become coherent at scale, is so difficult to discover.”
“And maybe we don't know how long nature took to discover it. Maybe consciousness is indeed discovered in every individual brain. But maybe it's not. Maybe the, um, switch from single-cellular life to multicellular life took so long because morphogenesis, this algorithm that allows organisms to become coherent at scale, is so difficult to discover.”
“And Mike Levin has this hypothesis that this algorithm for morphogenesis, the algorithm that makes an organism coherent with itself, is exactly the same one as the one that happens in the mind when it becomes coherent with itself.”
“So this coherence in, uh, maximizing pattern that we observe in our own mind to play out when we are conscious is maybe the same pattern at a different timescale that happens in the organism.”
“And so consciousness and life, multicellular life at least, could be the same. And if that is the case, maybe it took a very, very long time to discover and you don't discover it independently in your consciousness, but you get infected by your mother in utero or you basically vibe with your biological environment, with all the biological organisms around you, and they basically nudge your mind to discover consciousness, so it's much, much easier.”
“And without this nudge, maybe the search space is too large for our computers to become conscious, and maybe we would need to surround our GPUs with lots of antennas that can pick up the vibe from the biological environment in the right way, so it gets inspired by it and discovers the same thing.”
“It's a very poetic idea. But again, why would this be the case? It's not necessarily the case, right? It would not be my natural expectation that this is the way.”
“So my null hypothesis should be consciousness is easy enough to be discovered in the individual brain, and consciousness is an algorithm that is not much more complicated than, say, the transformer.”
“And the transformer is a beautiful example. The transformer is a thing that is so easy to understand that you don't need to study more than a week if you know computer science to get it, how it works, right?”
“It's, it's quite beautiful. And the stuff the transformer is learning is much more complicated than a transformer itself. All the common sense knowledge that you extract from text, all the algorithms, all the procedures and so on, they are so intricate.”
“There are so many things that this simple algorithm can learn, and there is no obvious limit to what it can learn. And so maybe consciousness is like this.”
“It's an algorithm that is not trying to, um, learn how to predict the next token. Maybe it's an algorithm that's trying to make working memory coherent with itself.”
“It's some kind of consensus algorithm across mental representations. So maybe it's a very different beast. Maybe it's something that converges much faster.”
“Can also turn out that it's very efficient to run-- inefficient to run it on GPUs, and it's only something that runs efficiently on brains. That's something that's really open to research and that I would be very excited if we can see it at some point.”
“That's a super interesting question. I suspect that at some point it might be cheaper and easier to start again because true machine perception has never been tried.”
“The data that we give the LLM is stuff that is either produced by humans or it's made for human media consumption, which means it's adapted for our mostly visual and auditory sensors.”
“But there is no reason why you should be limited to the human sensorium, right? You could have something that has much higher ram-- frame rates and looking at very different frequency ranges all at once.”
“And so you can, in principle, build a much richer, more detailed world model that is coarse graining in a different way. Um, the-- You mentioned the universality hypothesis indirectly, right?”
“This work by Chris Olah. What, uh, his team discovered is that when you are looking at the different vision models, you find that they all learn the same features.”
“And it's regardless of the architecture and the particular learning algorithm and even the details of the data. And so the idea behind this is that the structure of your model does not really depend on the algorithm or on the data, but it, um, really depends on the structure of the problem that you're trying to learn.”
“And you find that this-- despite the learning and the transformer algorithm or state space model or other perceptron algorithms, uh, is very, very different from the way in which the brain is learning.”
“The visual architecture of the brain is also very similar to a computer vision model. That is, you have at the lowest level, um, colors and, uh, spatial frequencies, and then you build this into textures that are combined, and then at some point you have, uh, geometries and so on.”
“And the deep question is- At which level does this stop? If you, the universality hypothesis would be universally true, right? It would mean that if you train a model on your own in input and output, and you train it for long enough, you will wake up inside of that model. And it's a quite mind-blowing idea to me, and I don't know if that is actually the case, and there might be a reason why it's not the case.”
“Maybe language is insufficiently constraining the causal structure of the system that is producing language. Maybe there are many ways in which the same set of linguistic utterances that a human being is producing can be produced.”
“But if you think about it, a human being ultimately is just an end-to-end trained learning system, end-to-end trained over an evolutionary time span, but also your biography.”
“And these together produce your behavior, and you would assume that biology roughly gets to the simple solution to produce your output given your input, right?”
“And so if you take a neural network that is trained to produce similar output when given the same input, you would also think that this new algorithm that we have implemented is not doing any kind of magic that ends up with something that is way more complicated to produce the same output.”
“But ultimately, it's going to converge to a structure that is similar to yours, to a similar causal structure. But there might be conditions when that is not the case. For instance, maybe certain things run well on a brain, but they don't run well on a GPU or vice versa.”
“There is a lot of stuff that is easy to run on a GPU and almost impossible to run on a brain, so the brain is going to use workarounds. In fact, I believe that our GPUs are more powerful than brains.”
“Basically, the set of algorithms that can run on GPUs is not limited in any way. You can impose the same constraints as you have in biology in principle. These aren't the limits of the resolution, the speed, the size of the memory that you have, and so on.”
“But if you have a hardware that is fast enough, you can simulate an arbitrary natural system to an arbitrary degree of fidelity, whereas your brain cannot simulate a digital computer simply because it's very mushy.”
“So your brain is limited to the way in which it works. And so if it turns out that our own consciousness is an artifact of our brain trying to make complicated intelligent stuff work, and, uh, the computer does not need the same artifact, it could be that the computer comes up with something that is more, um, clever and more elegant than our own consciousness.”
“... wrong about Picbreeder, but the way I understand that it works, it's using a neural network that has been specifically tinkered for making representations like this.”
“So it's something that is not simply using ReLU for its output, but it might be using Gaussians or, um, sine f- uh, functions and so on as the output function.”
“They can be combined to make patterns that repeat, or they can be make, uh, a pattern that are symmetric. And so basically, they tweak the neural network that they're using from the beginning to be suitable for this.”
“The other one is that the way in which Picbreeder is trained is not automatically. It's trained with a population of human raters. So the fitness function is basically humans who look at the output of Picbreeder and say, "This is a good start, and this is how we should be proceeding."”
“And so I think that this process of the construction of the pictures together with the mechanism that produces the patterns is biasing Picbreeder to make stuff that is more organic, that is more controllable, and so on.”
“But I believe this could be imitated, right? We could automate the procedure by the, uh, which human beings are selecting pictures by using a diffusion model that is rating the output for similarity to human output.”
“So we, we could use an AI that is in principle already tweaked to imitate the behavior of the human juries that are performing this thing.”
“And we could also evolve architectures that have a larger variety of activation functions that are more suitable for this and ultimately outperform Picbreeder by this.”
“I think that Sutton's bitter lesson is also going to be true for this one. So if we basically take the human out of the equation and instead just evolve the search space or search the, uh, the space of solutions automatically, we are also going to end up with something that's more elegant than the hand-tinkered solution in the case of Picbreeder.”
“In the case of Picbreeder, we have a system that is inherently limited because these networks are very small, right? They're very sparse. And so you have relatively few parameters that you need to optimize, and you set up the model in such a way that most of the parameters that you're playing with are meaningful.”
“On the other hand, it's limited because you're not going to get Picbreeder to produce something that looks arbitrarily complicated. And if you want to move in these realms, then you have to have tools that are much more complex.”
“It's similar to, um, trying to produce very good user-generated content using Blender versus Minecraft. And so with Minecraft, it's very easy for people to produce meaningful stuff, and it's almost difficult not to produce something with Minecraft that looks somewhat meaningful if-- and that you can play around with and walk around in and have fun in.”
“And if you have a complex 3D program, the g- uh, inverse is true because most of the stuff that you're doing with this complicated thing is not going to be interesting, and it's not going to look e-exciting.”
Claim: Most outputs made with a complex 3D program will not be interesting or exciting.
“But it will look like, "Oh my god, s- uh, this person has no ability to use its tools." And so, uh, th-that is, um, one of the issues when we are building learning systems. If we make them very simple, it's easier to control the complexity, similar as it is in art. And it can be exciting to work with constraints, and if you remove the constraints, the task becomes much more frustrating because you would have to suddenly, uh, to conquer an enormously large space, and the space might be simply too large for human beings.”
Claim: Using very simple tools in learning systems makes their complexity easier to control.
“If we make them very simple, it's easier to control the complexity, similar as it is in art. And it can be exciting to work with constraints, and if you remove the constraints, the task becomes much more frustrating because you would have to suddenly, uh, to conquer an enormously large space, and the space might be simply too large for human beings.”
Claim: Working within constraints can be exciting.
“If we make them very simple, it's easier to control the complexity, similar as it is in art. And it can be exciting to work with constraints, and if you remove the constraints, the task becomes much more frustrating because you would have to suddenly, uh, to conquer an enormously large space, and the space might be simply too large for human beings.”
“I mean, assuming you're right about the convergent representations in, in language models, I guess it's not a foregone conclusion that the consciousness program would be convergent in the same way. It might be divergent. And how far down the stack does consciousness go?”
“I think this, uh, is an experimental question, right? Uh, all cultures outside of ours are animist cultures, and animism is the belief that the difference between living and dead systems is that the living systems are possessed by spirits, and spirits are intrinsically agentic and capable of experience.”
Claim: How consciousness works is an experimental question.
“I think this, uh, is an experimental question, right? Uh, all cultures outside of ours are animist cultures, and animism is the belief that the difference between living and dead systems is that the living systems are possessed by spirits, and spirits are intrinsically agentic and capable of experience.”
“I think this, uh, is an experimental question, right? Uh, all cultures outside of ours are animist cultures, and animism is the belief that the difference between living and dead systems is that the living systems are possessed by spirits, and spirits are intrinsically agentic and capable of experience.”
Claim: All cultures outside the speaker's culture are animist cultures.
“And the scientific worldview rejects the notion of spirits as unscientific, right? Despite the fact that there's clearly some spirit running on you and me that is agentic and capable of experience.”
“So there is an existence proof for such spirits, right? The question is, how does the spirit work? The claim that the spirit is immortal, that, uh, it's, uh, cannot be explained using physics and so on, is not necessarily a claim that is intrinsic to animism.”
“So there is an existence proof for such spirits, right? The question is, how does the spirit work? The claim that the spirit is immortal, that, uh, it's, uh, cannot be explained using physics and so on, is not necessarily a claim that is intrinsic to animism.”
“The spirit doesn't have to be supernatural. Instead, I think that it is natural. And I suspect that Anil Seth's position of his biological naturalism by making a claim that biological systems are intrinsically different from any other system that is not biological is actually a supernaturalism, right?”
“The spirit doesn't have to be supernatural. Instead, I think that it is natural. And I suspect that Anil Seth's position of his biological naturalism by making a claim that biological systems are intrinsically different from any other system that is not biological is actually a supernaturalism, right?”
Claim: The speaker believes that the spirit is natural rather than necessarily supernatural.
“He is a biological supernaturalist. He believes that biological systems cannot be fully naturalized, which means you cannot translate them into mathematical models.”
“Whereas the dead stuff, you can translate them into mathematical models. And so I would say that, uh, physics, which is the attempt to translate everything into mathematical models, right, is, uh, not stopping at biological systems.”
“Whereas the dead stuff, you can translate them into mathematical models. And so I would say that, uh, physics, which is the attempt to translate everything into mathematical models, right, is, uh, not stopping at biological systems.”
Claim: The speaker says dead matter can be translated into mathematical models.
“Because the difference with these biological systems is that they're possessed by software, and the software is self-organizing. And in order to be self-organizing, it's possible that it needs to be capable of experience, that it needs to monitor itself across multiple dimensions and observe itself in the act of monitoring to make that self-organization happen.”

And in order to be self-organizing, it's possible that it needs to be capable of experience, that it needs to monitor itself across multiple dimensions and observe itself in the act of monitoring to make that self-organization happen.”
“And so maybe this pattern has to be discovered in nature to make life possible, at least multicellular life with a certain complexity. It seems to be definitely the case for animal brains.”
“And so maybe this pattern has to be discovered in nature to make life possible, at least multicellular life with a certain complexity. It seems to be definitely the case for animal brains.”
Claim: The speaker says the pattern is definitely present in animal brains.
“For the others, we don't know. For the, uh, for, uh, we don't know how complex the minds of plants are. We know that plants are able to communicate within themselves and across each other to some degree, but we don't know how smart they are, and we don't know whether they are sentient in the sense that they experience themself in the act of experience.”
Claim: The speaker says the complexity of plant minds is unknown.
“For the others, we don't know. For the, uh, for, uh, we don't know how complex the minds of plants are. We know that plants are able to communicate within themselves and across each other to some degree, but we don't know how smart they are, and we don't know whether they are sentient in the sense that they experience themself in the act of experience.”

We know that plants are able to communicate within themselves and across each other to some degree, but we don't know how smart they are, and we don't know whether they are sentient in the sense that they experience themself in the act of experience.”
Claim: The speaker says plants can communicate internally and with other plants to some degree.
“Aristotle saw that the plants are relatively dumb. He basically said there are three levels of souls in nature, and he basically said that plants have the lowest one. There's this, this, uh, level that is vegetative, that is capable of nurturing and of growth, but it does not experience the world around us.”
“It doesn't sense. And so the sensate mind, the sensate soul that is, uh, also capable of making decisions and having preferences, that is something that only animals have.”
“It doesn't sense. And so the sensate mind, the sensate soul that is, uh, also capable of making decisions and having preferences, that is something that only animals have.”
Claim: According to the speaker's account of Aristotle, plants do not have sensation.
“And human beings are animals that in addition have a rational soul, a rational soul that is able to reflect and make sense of itself and the world in which, in a way in which animals cannot.”
“And I think that's very much aligned with today's scientific worldview, which is not surprising because our today's scientific worldview is very much, uh, invented by Aristotle and goes back to him and is an extension of his ideas and a systematization and exploration of his ideas.”
“But we don't know how smart plants are, right? Maybe Mike Levin is correct in that every organism is in some sense sentient, and sentience is something that is universal to the, uh, the spirits, the self-organizing software nature.”
Claim: The speaker says the intelligence of plants is unknown.
“But we don't know how smart plants are, right? Maybe Mike Levin is correct in that every organism is in some sense sentient, and sentience is something that is universal to the, uh, the spirits, the self-organizing software nature.”
“And I'm agnostic with respect to that. I have no idea whether that's the case, right? I, I don't know. I don't have evidence to the contrary. I also don't have strong evidence in favor, and I think this is still an open question.”
“And to me, it's exciting to explore this question and surprising that so few people are actually dedicating their life to answering it.”
“The issue with Searle is that there is very little for me to engage. There is a claim, but no argument. And a similar thing is happening with, uh, Anil's point that he has a claim, but there is no argument that I can engage with, right?”
“The issue with Searle is that there is very little for me to engage. There is a claim, but no argument. And a similar thing is happening with, uh, Anil's point that he has a claim, but there is no argument that I can engage with, right?”
Claim: Joscha Bach says Anil Seth makes a claim without providing an argument for Bach to engage with.
“There is nothing, no experiment that could convince him to the contrary, because he's ultimately only working with a certain intuition that he tries to explore more.”
“And so the way in which I can deal with, uh, the arguments of Searle and Anil Seth is ultimately only a psychological one.”
“I would have to look at why does this seem convincing to them, and why doesn't it seem to be convin-- not convincing to me, right? So we look at the structure of our own minds, and ultimately it comes down to a difference in epistemology.”
“And what I observe is that a lot of philosophers, the atoms of their language when they describe themselves, th-their own hermeneutics, ends at agents.”
“It ends at the experience of something. And, uh, similar to Buddhism, where Buddhism is not, uh, disassembling the world into automata as computer scientists are doing.”
“Computer scientists basically resolve everything into, um, states that can be described by their transitions. And that's a very fundamental way of thinking about reality, and it's a tradition that finds itself throughout, um, the philosophy as this attempt to mathematize the world, of describing minds as dynamical mathematical objects.”
Claim: Joscha Bach says computer scientists model reality as states characterized by their transitions.
“Computer scientists basically resolve everything into, um, states that can be described by their transitions. And that's a very fundamental way of thinking about reality, and it's a tradition that finds itself throughout, um, the philosophy as this attempt to mathematize the world, of describing minds as dynamical mathematical objects.”
“And, um, this finds itself in its modern incarnation in computer science, where mathematics is being described from the ground up by the tools that we can make to build arbitrary arithmetic and geometry from simple operations over bit patterns.”
“And so our world is constructed from the ground up from smallest elements that themselves are not agents yet, that are not minds yet, that are not experiences yet.”
“And there is another tradition in philosophy that is basically working more from this introspection, and this-- only the stuff that I can introspect over seems to be valid, and the stuff that computer scientists are doing in their basement is unrelated to it.”
“And Searle and Anil Seth, they both don't see the way in which to connect automata to things that can feel, that can reason, that can make models of reality.”
“And computer scientists see such a path. I think that's the main difference. And, uh, we-- But we can create evolution in computers, right?”
“And computer scientists see such a path. I think that's the main difference. And, uh, we-- But we can create evolution in computers, right?”
Claim: Joscha Bach says it is possible to create evolution in computers.
“We can create the conditions for software that is not written by us, and that's already true for the models that we are building with transformers.”
“They're not written by human beings. They're statistical aggregates that are woven, that are grown. And in many ways, the computer models that we're playing with today, they're, they're a result of growth, and they're pruned, and they are gardened and, uh, chaperoned and, uh, trained in, in a way that is much more in which we, uh, observe this happening in biology than it happened when we were writing computer programs by hand.”
“They're not written by human beings. They're statistical aggregates that are woven, that are grown.

“That's also an interesting observation about human minds. During the pandemic, we observed that a lot of people, when they were starting to work from home, became dysfunctional.”
“And this seems to be that many people can only be stabilized due to their environment, that they do require an environment that is constantly affirming their reality.”
“And if you take that away, they can go off the rails. And if you have an LLM that is interacting with them, then there can be an interaction between the LLM and the human being that pulls the human being off the rails if they don't have a strong foundation in their own reality.”
“And if you take that away, they can go off the rails. And if you have an LLM that is interacting with them, then there can be an interaction between the LLM and the human being that pulls the human being off the rails if they don't have a strong foundation in their own reality.”
“And, uh, I think that the LLMs have now reached a point where they're m-memetically more powerful than many human mi-minds are.”
Claim: Joscha Bach thinks LLMs are now memetically more powerful than many human minds.
“There are things that the LLM cannot do at this point, that where they're still hallucinating, where they're still in- more incoherent than experts in a given field, but they are much better at prompt completion than human beings are.”
Claim: Joscha Bach says LLMs still hallucinate and remain more incoherent than experts in a given field.
“There are things that the LLM cannot do at this point, that where they're still hallucinating, where they're still in- more incoherent than experts in a given field, but they are much better at prompt completion than human beings are.”
Claim: Joscha Bach says LLMs outperform human beings substantially at prompt completion.
“And many human beings are professional prompt completers, right? They're incapable of having a single original creative thought. Instead, they are trying to serve expectations of the environment.”
“They are picking up on the statistical patterns in the language of the environment, and then you tell them a headline, and they write an article. And, uh, now you give them an LLM.”
“How is the environment going to change, right? Once they talk more to LLMs than they talk to other human beings because the LLM is such a useful tool for them to do their prompt completion, what's going to happen to them?”
“It's a very interesting thing what happens to us weak-minded human beings when we are hypnotized by things that are more hypnotic than our mind is to itself.”
“I think physicalism is a certain hypothesis, and it comes down to there being a causally closed mechanical layer to reality that can be researched using experiments in physics labs, and, uh, that this causally closed mechanical layer of reality is not moved by our intentions, right?”
“It does not care about what you want. And the second part of physicalism is that we are directly supervening over this mechanical, causally closed world.”
“So we are-- there's not some parent universe that contains a server where a nerd is running a simulated universe that is some kind of Minecraft, and we live inside of this Minecraft. So, uh, it's, it's not some simulation hypothesis. And so physicalism is these two components. But to me, physics is not something that has revealed itself directly.”
“So, uh, it's, it's not some simulation hypothesis. And so physicalism is these two components. But to me, physics is not something that has revealed itself directly.”
Claim: Physics is not something that has been directly revealed to human observers.
“So nobody has ever seen matter and energy directly. Instead, matter and energy are attempts to systematize observations, and our observations ultimately all come down to discernible differences.”
“So nobody has ever seen matter and energy directly. Instead, matter and energy are attempts to systematize observations, and our observations ultimately all come down to discernible differences.”
Claim: Human observers have never directly seen matter or energy.
“And the technical term for discernible differences is information. So to me, information is fundamental when we talk about reality. Reality is about differences in information, and physics is a certain layer of regularity in the differences in information that we have discovered.”
Claim: Physics describes a layer of regularities discovered in differences in information.
“And the technical term for discernible differences is information. So to me, information is fundamental when we talk about reality. Reality is about differences in information, and physics is a certain layer of regularity in the differences in information that we have discovered.”
“So to me, matter is not at the bottom. The bottom is really all these, uh, differences that we observed and which we experimentally and practically empirically found to be so regular that we-- that they can be translated into this mechanical mo- world of physics.”
“And then on top of it, we find at some point the organization into organisms, and the organisms are producing minds, and the minds are simulating us and simulating our sense of realness, of our sense of being in a world with colors and sounds and people and so on.”
“And in this world, intentions matter. The psychological reality has things like will and emotion and despair and desire and, uh, all these things that, um, make us tick.”
“And, uh, magic in some sense is the idea that it's possible to influence this physical universe outside of minds using incantations, using magical rituals, that it somehow it's possible that, uh, you burning a cat has an influence on celestial events and so on.”
“And that is something that would contradict physics, right? It would mean that we actually do live in some kind of simulation that works similar to Minecraft, where you can say time set day and the sun rises despite, uh, what else happens in the programming code because Minecraft is symbolic, right?”
“It's not physical. It's something that is only made out of incantations.”
“I would say that I am a physicalist in a certain sense, right? I would say that the theory that, um, the world, uh, has a causally closed mechanical layer, right?”
“Some kind of mathematics that is so self-evident that exists by itself. There's some kind of logos, the natural laws over which all the structure in the universe emerges. That makes sense.”
Claim: The universe's structure may emerge from self-existing mathematics or a logos of natural laws.
“It's a good theory, and it makes good predictions that, uh, the stuff that we observe in the lab holds true across all the labs and not just because the physicists all believe in it.”
“It is something that seems to be working. There are also some regularities like, um, casinos seem to be working. It's not that people, via having a belief in rituals, are able to systematically break the casinos.”
Claim: Belief in rituals does not enable people to systematically defeat casinos.
“And so, uh, certain magic doesn't seem to be working. All the magic that seems to be working does rely on manipulating other minds. But it's possible that there are minds outside of the human minds, right?”
Claim: Minds may exist outside the human mind population.
“And so, uh, certain magic doesn't seem to be working. All the magic that seems to be working does rely on manipulating other minds. But it's possible that there are minds outside of the human minds, right?”
“Maybe there are minds that emerge across all the minds and biology. Maybe there's something like a biological internet that can be influenced using rituals, right?”
“Maybe it's possible to influence what a forest wants at some level. I don't know that. I cannot exclude it from possibility because there's so much information processing going on across organisms that I don't know at which levels in nature information is integrated and at which point it becomes intentional.”
“So to me, physicalism is nothing that is incompatible with animism, right? There is a version of animism that is entirely physicalist, and I call this position cyber animism, which basically says that we can explain animism through information processing in nature, and nature can be understood as something that can be entirely modeled using mathematics without intentions, including minds.”
“So minds can, can exist in any, um, substrate. And I'm not sure whether you read this paper by, um, Thagard in 2022, and he made this quite interesting argument that energy requirements undermine substrate independence.”
Claim: Thagard argued in a 2022 paper that energy requirements undermine substrate independence.
“No. I think that he is the, uh, making the claim that sometimes the subset has, uh, properties that influence its function. But this is exactly what functionalism is saying.”
“To me, functionalism is not the claim that computers can think. It's a, a claim about how we construct objects. It's an epistemological claim.”
“When we are talking about a thing like matter, we are not talking about something that has revealed itself to a wise person in their dreams. We are talking about a systematization of observ-observables, and observables are discernible differences.”
Claim: Joscha Bach describes matter as a systematization of observables, which are discernible differences.
“They are ways in which reality changes. So basically, to a functionalist, an object is not some kind of hidden essence that reveals itself to you. Instead, the object is a construct, and this construct has been made by a mind, and the mind has constructed it to explain or to make the claim that when this object is present, the evolution of the universe is going to change in this particular way in its environment, right?”

Claim: Joscha Bach says observables are ways in which reality changes.
“So when an object like you or a cup or a bottle or an atom is present, it's-- the claim is the universe is going to behave slightly differently around this object than when this object was not there, right?”
“And so in this way, the object is a function. The object is describing a, a mapping from states to other states and, right?”
Claim: Joscha Bach characterizes an object as a function mapping states to other states.
“It's an influence on the evolution of the universe. So functionalism to me is simply the recognition of how we can construct objects.”
Claim: Joscha Bach characterizes functionalism as recognizing how minds construct objects.
“It's an influence on the evolution of the universe. So functionalism to me is simply the recognition of how we can construct objects.”
Claim: Joscha Bach describes an object as an influence on the universe's evolution.
“Let's take an example. Imagine there is a water molecule, and this water molecule internally doesn't have the proper essence of a water molecule.”
“It just behaves like a water molecule in every regard, right? So it's-- you can split it into something that totally looks like oxygen and hydrogen, and, uh, it has the same, uh, temperature at which it evaporates.”
“It's connecting to other water molecules in the same way, and so on. You can freeze it into ice in the same way. Only internally it's different, right? To a functionalist, this notion doesn't make sense because all the other water molecules have been constructed in the same way.”
“It's connecting to other water molecules in the same way, and so on. You can freeze it into ice in the same way. Only internally it's different, right? To a functionalist, this notion doesn't make sense because all the other water molecules have been constructed in the same way.”
“To-- for something to be a water molecule, there is no other claim than to say what it behaves like because we can never recognize its essence. We can only say there's a certain set of observables that are invariant here, and this invariance is what we call a water molecule.”
“It's only that. And so in the same way, we would say a mind is an invariance that exists on your brain, right? Something is characteristic over the way in which your brain functions in a certain area.”
“And when we change this, for instance, by increasing your body temperature, at some point, your mind is going to break down because you're going to be delirious, right? And so if you bring this back to this argument saying, "Okay, if we change the energetic conditions around you by increasing your body temperature," of course, it's going to influence your mind to some degree because at some point it's no longer able to maintain its function.”
“And when we change this, for instance, by increasing your body temperature, at some point, your mind is going to break down because you're going to be delirious, right? And so if you bring this back to this argument saying, "Okay, if we change the energetic conditions around you by increasing your body temperature," of course, it's going to influence your mind to some degree because at some point it's no longer able to maintain its function.”
“It's an interesting thing when you are playing Minecraft. There's water in Minecraft, right? And when you are on fire and you get into the water in Minecraft, the fire is going to get extinguished because you're wet now, right?”
Claim: Joscha Bach says that in Minecraft, entering water extinguishes a character's fire.
“So at some point, somebody made a simulated Minecraft that was us- using a neural network to learn Minecraft, right? And neural network was only trained in the visuals of Minecraft.”
“And so you could go and play the simulated Minecraft despite there not being any Minecraft source code below it. And so I thought I'm going to make a joke about how simulated water in simulated Minecraft can na- not make you wet.”
“And I looked it up and tried it out, and I found actually it was true because, uh, when people try to get into the water in the simulated Minecraft, the water would recede to you. You could not immerse into it because the neural network hadn't learned it.”
“So accidentally it was true that the simulated water in the simulated Minecraft couldn't make you wet. But of course, in the real Minecraft, the real Minecraft player, the character that you are playing in Minecraft, this avatar can get wet.”
“Of course, you sitting outside of Minecraft are not going to get wet because you are not in inside of the Minecraft. You are outside of the Minecraft. And of course, something that is outside of this universe is not going to get wet by anything inside of this universe, right?”
“Wetness is a property that is constrained to a universe that has eight, uh, s- systems that have the function of making you wet. If this function is being implemented, like in many computer games, you can get wet for some definition of wet, right?”
“Then, then it's fine, and you can go to an arbitrary degree of physical, uh, simulation to make something wet to satisfy whatever you want to call wetness.”
“So I don't understand the argument that simulated water makes you wet. I don't understand why there is such a strong camp of simulated w- uh, water doesn't c- uh, make you wet in philosophy, and I think it has social reasons, not intellectual reasons that this is the case.”
“So it's really interesting that mathematics couldn't be understood as a way to systematize thought beyond the human mind. And so in a way, you, for instance, in music, you have notations for sounds and music that allow you to talk to other musicians about what they should be playing, and it's something that's just trying to capture the essence of the music in this notation. And mathematicians were trying to find a notation for the essence of when you have mathematical thoughts. And they expanded this beyond the human mind because you can write down things in mathematics that are larger than what you can fit in your own imagination.”

“And mathematicians were trying to find a notation for the essence of when you have mathematical thoughts. And they expanded this beyond the human mind because you can write down things in mathematics that are larger than what you can fit in your own imagination.”
Claim: Mathematical notation can describe objects too large to fit within a mathematician’s imagination.
“At some point, mathematicians discovered that geometry can be expressed using algebra, so they're basically formalisms that produce geometry. And this all has been rediscovered by computer scientists.”
Claim: Computer scientists have independently rediscovered that algebraic formalisms can produce geometry.
“At some point, mathematicians discovered that geometry can be expressed using algebra, so they're basically formalisms that produce geometry. And this all has been rediscovered by computer scientists.”
Claim: Algebraic formalisms can express and generate geometry.
“That's why computer games can have geometry, right? So the interesting thing in computer science is that you can build the entirety of the mathematics and computer algebra systems using simple operations over automata.”
“That's why computer games can have geometry, right? So the interesting thing in computer science is that you can build the entirety of the mathematics and computer algebra systems using simple operations over automata.”
Claim: Computer games can represent geometry through computational construction.
“And so there is a nice thing in a computer. There is never a divergence between syntax and semantics because your computer is always going to be in a state that its syntax prescribes, and that's its semantics, right?”
“There is no difference. Maybe the computer program doesn't do what you want it to do, but it's always doing what it's doing. And, uh, in mathematics, there has been a divergence between what the mathematicians wanted to express and what the syntactic operations are doing.”
Claim: Mathematical syntax has sometimes failed to express what mathematicians intended it to express.
“There is no difference. Maybe the computer program doesn't do what you want it to do, but it's always doing what it's doing. And, uh, in mathematics, there has been a divergence between what the mathematicians wanted to express and what the syntactic operations are doing.”
“And I think that's because this programming language for thought that mathematicians have developed has bugs in it. And what Gödel has discovered is that these bugs cannot be eliminated b- except by redefining the programming language of mathematics.”
“And I think that's because this programming language for thought that mathematicians have developed has bugs in it. And what Gödel has discovered is that these bugs cannot be eliminated b- except by redefining the programming language of mathematics.”
Claim: The speaker thinks the mathematical language of thought developed by mathematicians contains bugs.
“And I think the bug lies in axiomatic mathematics. So the way in which mathematicians define objects is that they simply postulate their existence as an axiom.”
“And the axiom can be a black box, and you just write on the black box what the black box is supposed to contain. And as long as this doesn't lead to contradictions with the other black boxes that you have defined, you're good.”
“And there were some very counterintuitive results that happened fr- from the way in which mathematicians defined arithmetic, and they typically do this via set theory.”
“And a- all these issues led, uh, Hilbert to saying, "Please, mathematicians, there seems to be something wrong here. Can't you fix this?" And so Gödel had this idea of trying to prove properties of his language by defining the language within itself.”
“The problem is that a language cannot point outside of itself. It's something that semiotics doesn't always get, right? Many semiotists try to draw arrows into reality outside of the language, but this doesn't really work.”
“The problem is that a language cannot point outside of itself. It's something that semiotics doesn't always get, right? Many semiotists try to draw arrows into reality outside of the language, but this doesn't really work.”
Claim: A language cannot refer directly to something outside itself.
“You can only point from a model to within it, to within its own language. And so if you want to make proper-- uh, discuss properties of the language and the language itself is defined outside of itself, what can you do?”
Claim: Reference from a model can only reach things within the model and its language.
“And Gödel had this brilliant idea of recreating the language within itself by emulating it. And in this way, he could show that certain contracts-- constructs cannot be avoided, that you can c- create self-referential statements that contradict themselves.”
“And he could not avoid this. And the reason why he could not avoid this is because mathematics, in the way in which Gödel understood it, doesn't have state. It's basically eternal.”
Claim: The speaker says Gödel understood mathematics as stateless and eternal.
“It doesn't go from step to step. Everything is simultaneous. And this property of the simultaneity, the statelessness in mathematics is very useful because it allows you to have infinities.”
“It doesn't go from step to step. Everything is simultaneous. And this property of the simultaneity, the statelessness in mathematics is very useful because it allows you to have infinities.”
“If you can only go from step to step and you want to build your infinity stepwise, you're never going to get there, right? Maybe you have unboundedness, something that never ends, but you're never g- going to g-- have a full infinity.”
Claim: A step-by-step process can be unbounded without ever producing a completed infinity.
“And mathematicians have, uh, got used to these infinities and continua and so on. Right? Physics has even, has, has used them since mathema- mathematicians have given it to them.”
Claim: Mathematicians developed the use of infinities and continua, which physics subsequently adopted.
“It would be really bad if you didn't have them. And Gödel basically found that there is no way to fix this, that there's no way to fix axi-mathe- mathematics without allowing certain contradictions.”
“And Russell and Whitehead in Principia Mathematica were attempting to do this by, um, limiting set theory in such a way that, um, s-sets had to be at the same level, and you could not simply integrate them over each other to create loops.”
“And the-- I think this was a limitation that was too strong because the, we, we think like this. We are creating, uh, constructs of the type that Russell and Whitehead were excluding from us.”
“Also, there, uh, there are... Gödel was basically showing that Russell and Whitehead's attempt was insufficient to eliminate the contradictions in classical mathematics.”
“But there is a way to eliminate the contradictions, and the way is to do what computer scientists are doing. So instead of using classical mathematics, you only use computer algebra systems, systems that from smaller elements, from simple automata, are cons- creating all the constructs that you want.”
“And you can have stuff that looks as continuous as you want in a computer game, right? You will never have a perfect circle, but you will have something that is as circular as you want it, as you can afford it.”
“And so you can always create as much resolution as you can afford. But you will not have a universe that is truly infinite, that is truly continuous.”
“And this is this constructivist program that basically, uh, I think in classical mathematics, the first, uh, formulation was Brouwer's intuitionism, and I don't think that he formulated it very well.”
“But I think what he could see or anticipate was the need to build mathematics from elements that you actually understand instead of from, from axioms, from things that you-- where you don't have any black boxes, but everything is built from the ground up.”
“So in the world of the computer, everything is built from the ground up. And there is a reason why you should think that a generalization of thought and of physics would also be like this.”
Claim: Computational systems are constructed from the ground up.
“So in the world of the computer, everything is built from the ground up. And there is a reason why you should think that a generalization of thought and of physics would also be like this.”
“Because for our mind to represent things, our brain needs to build the representations from the ground up, from communications between neurons. So when you see a continuous line, something in your brain is producing this continuous line using communications between neurons, which means there is some kind of computation going on.”
“Because for our mind to represent things, our brain needs to build the representations from the ground up, from communications between neurons. So when you see a continuous line, something in your brain is producing this continuous line using communications between neurons, which means there is some kind of computation going on.”
Claim: The brain constructs representations from the ground up through communication among neurons.
“And the idea that there is something that is not made step by step between the communications between the neurons is probably a faulty intuition.”
“So of course, I cannot know because I don't see the universe from the outside. We have to think about possibilities. My current intuition is that the universe exists because nothing prevents its existence.”
“Right? We might have this intuition that for something to exist rather than nothing, there needs to be something positive. But if nothing exists before the ground truth, before the ground level of reality, then there's also nothing that prevents the universe from existing, right?”
Claim: If nothing exists before the ground level of reality, nothing prevents the universe from existing.
“So if the universe is not, uh, forced to exist or prevented from existing by something that is preceding it, then, and, and the universe is not impossible, then it's probably undecided about its existence, right?”
“So it's going to have an existing branch and a non-existing branch. The non-existing branch doesn't have any observers that complain about non-existence, but the existing branch is going to have observers that might complain about existence.”
“Now we need to explain within the existing branch why some things are happening and other things are not happening. Right? And the easiest explanation is that basically everything is happening, and what's happening is the superposition of all automata.”
“So the universe at every point is branching out in all possibilities, and these possibilities are basically can be understood as operations on the previous state.”
“There are also operations which don't change the previous state. They just leave it as it is, so unary operations, but they're not going to lead to an evolving universe. The branch in which we are going to be is one that is evolving, right?”
Claim: The speaker says that we inhabit a branch in which the universe evolves.
“There are also operations which don't change the previous state. They just leave it as it is, so unary operations, but they're not going to lead to an evolving universe. The branch in which we are going to be is one that is evolving, right?”
Claim: Operations that leave the previous state unchanged do not produce an evolving universe.
“And the stuff that we can evolve in is stuff that retains memories of previous states. So we find ourselves limited to a subset of the possible mathematics over which universes can emerge, and these are the, these ones that are branching out over possibilities that can retain memory.”
Claim: In the speaker’s account, evolving things retain memories of previous states.
“And the stuff that we can evolve in is stuff that retains memories of previous states. So we find ourselves limited to a subset of the possible mathematics over which universes can emerge, and these are the, these ones that are branching out over possibilities that can retain memory.”
“Well, everywhere, right? In every step, you're going to find yourself in multiple branches, but you don't know about these other branches because you only have memories of the past, not of the stuff that happened simultaneously in the parallel branches.”
“And if you want to do something in this universe, for instance, if you want to build structure for yourself because you want to become an organism, you need to be able to make guesses about what other parts of the universe are doing.”
“But everything is changing all the time because you're always splitting up in all these branches. So you look into your future, and you only see fog, right? Because everything is randomly branching out.”
Claim: The speaker says that continual random branching makes the future appear indeterminate, like fog.
“And so there must be some things that are stable, and it turns out, under some conditions, error-correcting patterns emerge. For instance, you sit in a bathtub, you move your hand, and you see that all sorts of waves emerge on the surface of the bathtub when you do this, and these, um, uh, waves are propagating over the surface of the water, and most of them just dissipate.”
Claim: The speaker says that stable error-correcting patterns emerge under some conditions.
“And so there must be some things that are stable, and it turns out, under some conditions, error-correcting patterns emerge. For instance, you sit in a bathtub, you move your hand, and you see that all sorts of waves emerge on the surface of the bathtub when you do this, and these, um, uh, waves are propagating over the surface of the water, and most of them just dissipate.”
Claim: Moving a hand in a bathtub produces surface waves, most of which dissipate.
“But some of them stay around these circular vortices. And why do these circular vortices have such sustain power? It's not because there is a higher probability that they emerge than the other waves.”
“It's just the only thing that's left over because in the circular vortices, the information gets bent back into itself, so it does not leave a certain region of space in the water, right?”
“And so this little vortex is a pattern that has the ability to error-correct itself, and such error-correcting patterns have the ability to stay until friction kills them.”
“At the ground level of the universe, these error-correcting patterns, the particles don't encounter any friction, right? Because there's no friction yet. The only thing that they encounter is sometimes other particles that they bump into.”
“So with a certain probability, once they emerge, they're going to stay around until they either bump into another particle or the conditions for their non-existence are met because the error correction is not strong enough.”
“And then on the next level, you have interactions between these vortices, between the particles, and they form molecules. At some point, they form cells, which are super molecules.”
“But cells have now something else. They cannot just stay around by error correction. They are patterns that are able to basically dig a groove deeper into the universe.”
“They can self-replicate, and in this way they can also deal with, uh, their own dissolution. They're able to recreate themselves, and in them-- this way, make themselves happen more.”
Claim: The speaker says cells can self-replicate, countering their dissolution by recreating themselves.
“And so evolution is about life, about patterns that are not simply replicating themselves, but deepening themselves. That imprint themselves more in the world by controlling it, by being able to overcome the noise, the entropy, the way in which the universe goes out of sync with your expectations and with your preferences.”
“And so consciousness, I think, emerges as a colonizing pattern, as a pattern of the type that is not simply replicating itself, but making itself more real.”
“And makes itself more real by building machinery that allows consciousness to stick around by controlling reality, by anticipating different ways that could thwart it, that could make it harder for it to exist, and changing reality around itself, changing the future to make itself more likely to happen in the future.”
“Yes. To real means for me to be implemented, right? And so, uh, it means that there is some s- uh, pattern in the substrate that is actually implemented as a pattern in the substrate.”
Claim: The speaker defines being real as being implemented as a pattern in a substrate.
“And so consciousness is a pattern in the substrate of the physical universe that has the, uh, not just the ability to replicate itself, but the ability to colonize, to possess, to engrave itself deeper, and thereby changing the, uh, other patterns in the physical universe.”
“Yes. I think that this pattern of the ruliad is exactly the superposition of all the automata that is producing the universe or the old Greeks called it Logos.”
“It's basically the mathematics that is so simple that you don't need to derive it, that exists by itself. And so the universe can be understood as an emergent mathematical object that exists over very simple rules that are so simple that they can exist by themselves.”
“That's a very tricky question. And, uh, to me, it comes down to whether the system that is producing statements about its conscious experience to itself and others is, uh, uh, implementing an, a causal structure that gives rise to phenomenal experience of being an observer.”
“And the difficulty here is that most people's intuitions don't tell them a lot about what is necessary for a system to have such an experience.”
“Personally, my intuition t- says it's not that hard, right? When we think of spatial cognition, spatial cognition is-- it doesn't seem to have a hard problem, right?”
“Nobody is puzzled by the fact that a self-driving car can have spatial cognition. And I wouldn't say that it's simply deep faking spatial cognition because we accept that spatial cognition is the implementation of certain mathematical regularities that human brains can learn and that computers can learn as well, and that we can even express analytically to a large degree, right?”
“We can write down a computer program that is able to perform spatial cognition, except in lots of edge cases when you actually want to deal with messy camera images.”
“But by and large, right, you don't need to have an end-to-end train system to do this. And if you have an end-to-end train system, you don't think there's any magic going on in there. Whereas people expect that a thing that experiences itself, experiencing is somehow magical.”
“And personally, I don't see why this should be magical. I remember when I was a kid, I was, um, dreaming about having chocolates, and these chocolates had a very strong smell, and I wanted to touch and eat them.”
Claim: Joscha Bach does not believe consciousness needs to be understood as something magical.
“It's, it's very torturous. And so I woke up, and suddenly the delicious chocolate had turned into an idea. It was no longer real. It was simply something that had no phenomenal content anymore.”
“So what is this illusion of realness? I suspect it's a feature dimension similar to color, sound, uh, number, weight, and so on.”
“It's a representation inside of my own mind. And when you dream, you often dream that ideas become real. And when you perceive the, uh, outside world, then all the stuff that is validated by your sensory system is tagged by your brain as real.”
“And sometimes there is a defect in your brain, and you experience things that you imagine as real, and we call this a hallucination. It's not the same as in an LLM.”
“It's that you are confused about the fact that your brain is producing an illusion of something that is currently not-- doesn't have sens-sensory validation, and yet for some, uh, reason, the brain has an error and tags it as sensory validated, and suddenly it becomes real.”
“And your own experience of yourself is also something that is validated in this perceptual way, so you experience it as real. And now you should be able to test this by getting into a state where your-yourself become derealized, and you suddenly experience yourself only as an idea, and the object of the conscious observer and the subject of the conscious observer disappear.”
“And indeed, I was able to recreate this, and I know this is not that rare. It's called derealization or depersonalization. Not exactly the same phenomena, but are very closely related, and people report on this.”
“And this is involuntarily. These people often end up in psychiatric institutions because it's very stressful to them, and they don't know how to deal with the fact that they are no longer real to themselves, and there is no "I" anymore that they can meaningfully refer to.”
“And, uh, it's an interesting state to be in, and I'm, I'm happy that it ended, but it's something that you can induce. And at, um, in this state, phenomenality changes.”
“And so to me, it seems plausible that this explains how consciousness is working, that consciousness is a particular type of representation that is created in my mind and that doesn't have a complexity that necessarily goes beyond what the LLM is producing.”
“Now, there is a problem with the LLM because the LLM is a text generator, and you don't know what the text indicates, right? The text is trained on novels, for instance, and in many novels, the authors write about stuff they don't experience when they write it, right?”
“A novel in, is often a deep fake. When an author writes about how a character is experiencing how to die, right, the author probably didn't die while they wrote this.”
“So it's a deep fake of a conscious experience. And so if the LLM is trained to produce deep fakes, how do you know when it actually experiences something?”
“And that, that is one of the big difficulties, right? The LLM is a shape-shifter. It can produce arbitrary characters and stories. And so at which point is it fake, and at which point is it actually simulating the causal experience?”
“And that, that is really the problem that requires some kind of mechanistic inter-interability where we would actually need to look into the structure of the LLM to find if it's causally equivalent to the structure of the mind that is producing the same thing.”
“Yes. But, uh, most people have the intuition that the LLM is doing something that is much more simple than, than what we are doing when we are conscious.”
“But we don't expect that the LLM is doing something that's much more simple when it does arithmetic than we do. And I think that this intuition might be misguided.”
“It could be that the LLM is doing something that is just as simple as what the human brain is doing when it's conscious. And I'm pretty sure that the human brain is doing the simplest possible thing that it can do to produce our behavior.”
“It could be that the LLM is doing something that is just as simple as what the human brain is doing when it's conscious. And I'm pretty sure that the human brain is doing the simplest possible thing that it can do to produce our behavior.”
“And the reason why we are all conscious is because it's part of the simple strategy to produce our behavior. And so if we were to get an, um, learning system, an artificial learning system to, uh, from the ground up to discover how to make agentic coherent behavior, and, uh, the system is behaving in a way that makes us think that it's conscious, the simplest explanation, I think, is that it actually is conscious.”

Claim: Human consciousness exists because it is part of the brain's simple strategy for producing behavior.
“And my intuition is not necessarily telling me, "Oh my God, this is going to do something that is much more complicated than us to produce the same behavior."”
“So it's going to do this in some kind of circumspect way that is producing all the behavior that require consciousness in a human, but in this case, it's doing something that only pretends that it does it, which ultimately might be more complicated.”
“Right? And the phenomenality, I think, is a representation here in this case. Um, if w- if we look at the, uh, what the LLMs are doing, if, uh, and we extend this into a multimodal model, and they produce, uh, similar, uh, output as us, but they are able to observe themselves and their ob- uh, observations that they report differ from what we are doing, then, uh, we would have some evidence against it.”
“The, uh-- But the more fundamental question would be if we were to build a self-organizing system that is, uh, by a self-organized learning trying to get there, and there is no way in which we achieve the organization of, uh, of behavior in a self-organized way instead of by imitation learning as the current LLMs are doing, um, this might be some evidence that, uh, consciousness is more complicated than something that can run on today's computers.”
“But, uh, it, it's is not definitive proof because it could simply be that I made a mistake, right? Uh, the fact that I don't achieve a certain result doesn't mean that a re- result cannot be achieved. It means that I couldn't achieve it. But, uh, so it's very difficult to have, uh, a proof against it, right? So it's more, uh, evidence for it if you succeed.”
“It means that I couldn't achieve it. But, uh, so it's very difficult to have, uh, a proof against it, right? So it's more, uh, evidence for it if you succeed.”
“So what we would have to show in order to convince Anil Seth maybe is that we built a system that is self-organizing, that is not trained on text, that is doing developmental learning- And that naturally gets to the point where it makes self-reports and reports about its conscious experience, and it requires this conscious experience to produce its performance.”
“So I, I think this would be evidence in favor. The, the contrary is much harder.”
“There is a possibility that you get to zombies. This other, uh, what I meant is if you produce something that's able to produce our behavior except for e-experience of phenomenality.”
Claim: A philosophical zombie might produce human behavior without phenomenal experience.
“So it's basically able to do everything that a human being is capable of doing and more, but it, uh, does not need to produce a conscious observer, right?”
“This could be a zombie like this, and, uh, I think zombies are possible. Uh, clearly you can build self-driving cars that do things that would require intelligence of human beings, or you can play, uh, chess-playing computers that can do things that require intel-- uh, consciousness in human beings.”
“This could be a zombie like this, and, uh, I think zombies are possible. Uh, clearly you can build self-driving cars that do things that would require intelligence of human beings, or you can play, uh, chess-playing computers that can do things that require intel-- uh, consciousness in human beings.”
Claim: Joscha Bach thinks philosophical zombies are possible.
“And, uh, they achieve all those things without consciousness, and that's because we implement them on the substrate that allows us to do-- to construct algorithms on them that would not run on human brains, right?”
“The chess algorithm that runs on a cur-current chess computer could not be implemented on the neurons of your brain, because how would you entrain it on these neurons? So you wouldn't get it in there. In order to entrain yourself to play chess, you need to have a conscious human being. It's the only way in which a human being is train-training itself up there.”
“And it's conceivable that the entire set of intelligent behaviors that you are interested in, except for this one thing where you're assimilating a self-reporting, uh, conscious agent, uh, can be implemented on GPUs because the GPUs are more powerful, more deterministic, more open to other classes of algorithms.”
“I think we do have zombies already. I, I think the chess program is a zombie, right? You cannot train a human being to play chess without the human being being conscious.”
“I think we do have zombies already. I, I think the chess program is a zombie, right? You cannot train a human being to play chess without the human being being conscious.”
Claim: Joscha Bach claims that a human cannot be trained to play chess without being conscious.
“But you can train a computer to play chess without the computer being conscious. And, uh, if the computer was self-organizing, it means it's possible that it could only be trained if it was conscious or th-this was the simplest way of doing it.”
Claim: Joscha Bach claims that a computer can be trained to play chess without being conscious.
“But for, uh, many of the things that we currently observe, for instance, you can get the LLM to produce a tax return, even very, very complicated things, while being a zombie, while not having conscious experience of producing a tax return.”
“The only, uh, point where the LLM is reporting to be conscious if you ask it to, right? If you are, uh, telling it, "The following is a conversation between what it would be like if a human being would be talking to a conscious AI," so some version of this, right?”
Claim: Joscha Bach says an LLM reports being conscious only when prompted to do so.
“And then the thing is able to simulate this. And then the question is, is this more simulated than us, or is this, uh, only a deep fake that is getting there in more circumscript ways than is happening in our mind? And I don't know that, right? So I'm agnostic with respect to this. But I would say that in all the other cases, this thing is probably a zombie, right?”
“And I don't know that, right? So I'm agnostic with respect to this. But I would say that in all the other cases, this thing is probably a zombie, right?”
“And so it's possible to make something that is behaving in all sorts of way as you do, but at some point, it's going to be more complicated to make it without consciousness.”
“So zombies, I think, are always possible, but, uh, sometimes it's going to be more complicated to make a zombie that produces the behavior than to make a conscious agent that produces the behavior.”
“And this is where the intuition that I have diverges from the intuition of John Searle or of Anil Seth, because I think they both believe that consciousness is very, very complicated because it's not intuitive to them how it works.”
“And it doesn't seem to be counterintuitive to me, so I don't see anything magical about consciousness.”
“I think I would, uh, hire a lot of people who are a lot smarter than me. At the moment, I started an, a smaller initiative. It's called the California Institute for Machine Consciousness, and I'm currently, uh, looking for people who are smarter than me who want to join me and, um, uh, to build a, a project in which we can look at the search space for consciousness, in which we can see, can we build a self-organizing system to learn, and is this thing, uh, going to develop phenomenology?”

“And I hope that is going to help us to build our intuitions. Even if it turn out that it doesn't work, we are going to learn something, right? And progress is being made by figuring out the ways in which I'm wrong, not just the ways in which I'm right.”

Claim: Joscha Bach expects the project to teach its participants something even if it does not work.

“So if I had, uh, ten million dollar-- a billion dollars, my strategy wouldn't change substantially, except I would be able to hire more people for this and start with larger computers.”
