I've been enjoying the Culture series by Ian M. Banks a lot and I'm currently reading the second novel. It's about a future where a part of the Universe lives in the Culture, a society governed by superintelligent AIs. It's objectively cool, but also deals with deep questions like "What do you do as a human, if you don't have have to do anything?".
