While the book didn't have too much new information to offer for me, people new to Artificial Life will no doubt find this book incredibly interesting. From basic ALife principles to why BT uses sex to optimize its networks...excellent stuff.
The book looks as much into robotics as it does into software, something else I appreciated. All the "greats" are covered: TIERRA and Thomas Ray, Rodney Brooks and all his robots, and a variety of others. It was a great mixture of history and information.
The book also has a very sobering last chapter that actually did change the way I look at human beings and intelligence.
Conclusion: Excellent book, not much new ALife veterans, but for beginners - you won't find better.
