And if you could build an AI smart enough to do all that, then it might logically conclude that the one thing all the problems you describe have in common is humans. I don't think there's any simple or easy solution to these problems. They're messy human problems with vested interests, and smart people are going to have to work hard, together, to implement even partial solutions. Government and politics are unpleasant and can go horribly wrong. But I've come to distrust all simplistic answers that begin, "All you need to do is X", whether "X" is "privatize everything" or "invent benevolent AI" or "allow the state to wither away in favor of an enlightened proletariat." No, I think we need to work very hard, be smart, and try to find common ground with as many other people as we can. And if merely sort of works, we should count ourselves lucky.
