I read this book because it was on the reading list of an OU course on Natural and artificial intelligence (M366). As such I expected the book to cover the subject in some detail. In contrast to Geoffrey Cockayne (who has also reviewed this book) I found this book disappointing. I felt the treatment of the material was too shallow, even allowing for the fact this book is an overview of current research.
There is also a sense that the American author was somewhat inward looking towards the US when looking at researchers. The first 80% of the book mentioned American researches in abundance and, to my recollection, almost entirely ignored the rest of the world. This is not a true reflection of research projects relevant to the book. However the last 20% of the book did give brief mention to research in Japan, Switzerland and the U.K.
The author has also made some basic technical errors, reminiscent of the errors made by `technical authors' when writing `popular science' books. I would therefore put this book into that category. It is not a book that has much to offer for anyone who is studying the subject in any depth and is looking for meaningful detail.
On the positive side it does give a flavour of what is being researched.
Also note that this book was published in 2005 and the most recent source material quoted by the author was February 2003. At the time of writing this review in October 2009, this makes the material in the book six and a half years old which probably makes it out of date. The copy I received was a first edition.
