Any good sci-fi out there that isn't apocalyptic, post-apocalyptic, or some form of capitalism in the future? You know, some kind of portrayal of a better world is possible? Star Trek is an obvious one but I'm scratching my head trying to think of other examples.
Greg Egan's Diaspora is a hard sf novel set in year 3000 where most of the planet is given up to nature and the majority of humans, billions upon billions of them, live in like five 10 meter cubic supercomputers powered by geothermal energy. One of my favorite novels but you have to be a huge nerd to really enjoy it.
