Ian M Banks. The Culture series is the most splendid collection of books I’ve ever read. Some are better than others but collectively they build an insight into a galaxy spanning civilization.
It just comes down to my preferences for what kind of itch I liked scratched the most. Egan stretches my brain and makes me wonder at the complexity of complexity. But Banks makes me yearn for the future. Demonstrates what wonders could be possible if we fast forward technological development forward 10k years.
The magnificent intellects of the artificial minds that govern the society hits me in my soul. What a wonderful idea.
