One of my favourite authors, Iain Banks, divided his time between non-genre fiction and SF (where he wrote as Iain M Banks). Much of his SF involved stories about, or involving, a highly advanced society called The Culture that features governing AI's. The books are provoking and written in an engaging style - anyone who has crawled to the end of a turgid book with a sense of relief rather than achievement will know how important this is - and include a perfect measure of wry humour.

I would strongly recommend any and all of Banks' output, non-genre and SF alike. However, since this is a post about SF, I would suggest starting with "Consider Phlebas", the first book in The Culture series.

Even the incredibly inventive names Banks gives to places and people are a delight all in themselves. For example, one of the Culture spacecraft is named "Experiencing a Significant Gravitas Shortfall"...
