The Rifters Trilogy, also by Peter Watts is a great read as well. It focuses a bit more on the transhumanism aspects but non-conscious intelligence is a secondary theme of the last two books. Pretty much any book by Greg Egan covers these ideas since nearly all of his stories take place somewhere in a shared universe at different points of humanity approaching the singularity. Check out his short stories in Axiomatic or the full length novels Permutation City and Schild's Ladder.
