The Quantum Thief by Hannu Rajaniemi.

It's chock full of ideas that any technologist would find fascinating. A post-singularity society in which those who "got there first" ascended to technological godhood, and the rest mostly fight for comparative scraps. Those scraps are phenomenally interesting though, and the many ways the book assumes and implies generations of growth in technology make for some truly out-there settings and cultures. If you liked the part of Anathem where you had no idea what was going on at first, but slowly learned the ways of the world as you read on... you'd love this book.
