Someone there mentioned never having heard of the sequel, so.. FYI, there's a sequel! It's called Freedomâ„¢[0]. It's very much one story split into two volumes, not "our heroes go on a new adventure".
And as I said in that thread, for another great fictional portrayal of AI, see Person of Interest[1]; it starts as a crime procedural with an AI-flavored twist, and ended up being considered by many critics the best sci-fi show on broadcast TV.

His recent work is great too. Also I've met Dan a few times at Defcon and he's a really great and interesting guy.
