Diamond Age is my favorite. He paints a picture of a post-cyberpunk future where nation states have been replaced by voluntary borderless collective organizations. There is, of course, fantastic technology interweaved with an epic battle over the future of civilization.

But the best part of the book is his detailed description of a private anonymous universal mesh-net that replaces the internet as we know it. Inspiring stuff. I think we're a lot closer than you might expect. 😉
