So this book was a bit confusing at times, sometimes it jumped around and there were a few things left unexplained. However, for all its minor annoyances, I still loved it! AI + the future+ talks of the nature of consciousness + ALIENS= a great thought experiment that makes your brain hurt (in a good way). I enjoyed every minute of it, and it was pretty long. I even read the afore- and afterword. Superb, another great one from this author.
