A must read on the current state of AI that is not loo long so if you can get it from a friend I might be inclined to do that. The middle chapters read like a Harlan Ellison sci fi except the future is here, now and is as dystopian as anything dreamed up in fiction. If you are adversely affected by fictional accounts of the end of mankind you may want to skip this and carry on in blissful ignorance as this lays out just one of an untold number of endgames where we create something we don't understand, can't control and perhaps considers human wants and needs as much as we worry if the ants in our foundation are well fed. If you've watched alphago and were amused at the hubris of lee sedol or shocked by the confusion of the dev team at the actions of the program they created this is that 100x.
