I don't know where everyone is getting these in depth understandings of how and when sentience arises.
It's exactly the fact that we don't how sentience forms that makes the acting like fucking chatgpt is now on the brink of developing it so ludicrous. Neuroscientists don't even know how it works, so why are these AI hypemen so sure they got it figured out?
The only logical answer is that they don't and it's 100% marketing.
Hoping computer algorithms made in a way that's meant to superficially mimic neural connections will somehow become capable of thinking on its own if they just become powerful enough is a complete shot in the dark.
