Google's AlphaGo AI defeats the world's best human Go player

Google's AI star, AlphaGo, wins again. It bested Ke Jie, the world's best Go player, by just half a point -- the closest margin possible. After the match, Google's DeepMind CEO Demis Hassabis explained that this was how AlphaGo was programmed: to maximise its winning chances, rather than the winning margin. This latest iteration of the AI player, nicknamed Master, apparently uses 10 times less computational power than its predecessor that beat Lee Sedol, working from a single PC connected to Google's cloud server. We've embedded the entire match here, but for those not completely up to speed with Go, the AI player picked up a 10-15 point lead early on, which limited the possibilities for Jie to respond.
