I just read Saturn's Children by Stross. Its set in a future where humanity proper has gone extinct and been replaced by robots that have fundamentally neuromorphic brains with approximations of Asimov's laws and some other safeguards hacked in. The main character and several aspects of the plot are heavily inspired by Heinlein's Friday. I strongly recommend it if and only if you like Heinlein and/or Stross'es other books.
