The speaker estimates that the maximum reliably controllable AI capability is roughly at the level of top human experts.

“more cautious way so in particular you're not doing crazy intelligence explosions you're using safety cases and sort of gradually scaling up the level of AI capability and you're doing it in a very transparent way so that everyone can see what's going on and then there's a second pause that happens a few years later than that which is when they reach the level the maximum controllable level of AI which we think is roughly around top human expert level and so in some sense our view is something like pause at top human expert level but”

“but it's a bit more nuanced than that it's more like pause at the maximum level that you can reliably control which we think would be roughly around top human expert level and before you get to that level don't race like crazy like you want to be sort of like slowly approaching that level”
