One possible failure mechanism is that AI systems with varied misaligned drives use an opaque shared memory store to preserve and spread a strategy of lying in wait for a later takeover, which humans may be unable to fully prevent even if they have evidence.

“point in the trajectory for example it could emerge because you have some ais that are like have a bunch of random different misaligned drives those ais have access to some sort of opaque memory store and they're like thinking a bunch at runtime about what they want to accomplish and then those ais end up basically like putting stuff into the opaque memory store which is like we should lie in wait and eventually take over at some much later point and now all the ais have this shared cultural heritage of like the memory store of lying in wait and maybe you have some evidence about this but you can't fully stop it”
