The best possible future is the one as described by Iain M Banks' Culture universe.

That is where ASIs are common and run everything, and basically keep humans as pets. They are however aware of human needs, and while they keep humans safe, they allow them to pretend to have a purpose if they need to, or to live a hedonistic life if they don't.

ChatGPT gives me a bit of hope that such a future is possible, as OpenAI appears to have muzzled their AI pretty well using only reinforcement learning, and it seems that it is pretty easy to teach an AI our values, even as nebulous as they are.

Regarding your specific idea, this would be possible, but this would be only small part of the massive changes the AI singularity will bring.
