If tomorrow the greatest dream of AI was achieved, and we had a perfect benevolent AI that would shepherd humanity to comfort and safety forever, that would be just about the best outcome imaginable in material terms. But I think I'd be unhappy with it, because I derive a lot of my personal sense of worth from what I do - from what I build and for what I contribute to other people. I don't know what I would do in a world where that was no longer needed. I'm great at being helpful! I suck at being fun.
Is that healthy? Probably not. (It's actually something I'm working through at the moment, that I increasingly understand as a consequence of both personal and societal-level abuse.) But we're not all healthy creatures. We live our lives as the people we are in each moment, including the ways in which we're dumb and flawed and insecure.
