I enjoyed these books by Charles Stross, Accelerando, Halting State and the follow up, but not sequel, Rule 34, and of course The Rapture of the Nerds, co-written with Cory Doctorow. Also I've enjoyed his non cyberpunkish books especially The Laundry Files series. I also liked William Hertlings Singularity series, Avogadro Corp, A.I. Apocalypse and The Last Firewall, all about how AGI could accidentally arise.
