Thanks ... I really appreciate the kind words. MIT Press has repeatedly tried to get me to do a 2nd edition and while it was tempting, I always ultimately decided that it was better to keep doing new things. Although, much to my surprise, a Japanese edition of the book just came out this year so there still seems to be some interest.

But that said, I am working on another book now that is meant to be a more accessible successor to CBofN and something of a computational "theory of everything else". I'm about halfway done, but the it's hard to write with the distraction of living in this bizarre timeline of ours.
