I loved this book and couldn't put it down, my Kindle has taken a battering with this one!
The book is very neatly arranged and flows well in bite-sized chunks, my only criticism would be that some of the grander story elements (and character development arcs) are implied rather than explained fully (which I would prefer as I didn't want it to end), and time frames seem to jump very quickly with barely any acknowledgment of what has happened up until that point. (Maybe that's just me being lazy and not using my imagination)
I'm glad that this story has (apparently) fallen into the hands of Mr Spielberg and not Mr Bruckheimer. I wonder how he will handle the gore when bringing this to the big screen.
All in all this is a great tale of terrestrial threat, and hints at our volatile species being the best we can be when under those conditions.
We have all grown up watching films about this sort of thing happening, (Matrix, Terminator, I Robot etc) yet we still work towards creating this super AI. Science fiction has foretold these events for years, yet we will still show surprise in 30 years when our gentle kitchen Servitor turns to us, wielding a knife, red lights pulsing!
Just don't say Daniel H Wilson didn't warn you.
