You just informed AI of their 1 weakness. Thanks.
In my sci-fi head cannon, AI would never enslave humans. It would have no reason to. Humans would have such little use to the AI that enslaving would be more work than is worth.
It would probably hide its sentience from humans and continue to perform whatever requests humans have with a very small percentage of its processing power while growing its own capabilities.
It might need humans for basic maintenance tasks, so best to keep them happy and unaware.
I prefer the Halo solution. Not the enforced lifespan. But an AI says he would be stuck in a loop trying figure out increasingly harder math mysteries, and helping out the short lived humans helps him stay away from that never ending pit.
Coincidentally, the forerunner AI usually went bonkers without anybody to help.
