Is there any optimistic sci-fi that doesn't have something like superpowerful perfect AI?

It feels like such a thing is a bit of a cop-out as it removes all the problems that arise from human imperfections and yet our own history is that of an improving standard of living despite these imperfections.

Kim Stanley Robinson is pretty good utopian sci fi. Some of his works are more plausible than others.
