I fear that the title and blurbs for this book will narrow its appeal to nerds and sci-fi fans (I include myself), which would be a shame because David Dufty has done an impressive job of exploring fundamental questions about what it means to be human and what role the attributes of that humanity play in how we interact with "thinking" machines.
Dufty has also managed to combine elements of a mystery, an adventure, sci-fi, and social commentary without letting the seams between those story threads become so visible to the audience that they disrupt the narrative flow. If this sounds a bit like the goals of the project which created an artificially-intelligent android of famed science fiction author Philip K. Dick, well, there you go. Dufty's role in that project gave him up-close access, but to his credit he also maintains perspective and reports on the ups and down of the team's efforts with some objectivity and distance.
The edition I read is a pre-publication proof and if I were the editor I would make one significant change prior to the announced on-sale date of June, 2012. Lose the Introduction. As writers have been taught since time immemorial, a great way to start a book or story is "in medias res" -- in the middle of things. Chapter 1 does this with a "grabber" lede worthy of a master journalist: "In December 2005, an android head went missing from an America West flight between Dallas and Las Vegas." You'd have to be -- pardon the expression -- brain dead not to want to keep reading. Compare that to the intro, which starts out, "In 2005, I was a postdoctoral researcher at the University of Memphis ..." You get the idea.The info about the author which follows would be much more appropriate to an appendix or note at the end of the book, when any doubts about the veracity of the story would either be resolved anyway or could be further addressed by Dufty's credentials.
Another small complaint is the low-quality photos, which are a slight disappointment, but may be all that are available. They do, however, manage to convey the inevitable creepy feelings we experience when looking at a lifelike android whose face is so very human, but whose head visibly reveals wires and motors. The contrast is very unsettling and like the book in its entirety, effectively raises the big issue of how humanity will want to relate to its own creations in the very near future.
