What Alpha Go means for the rest of us?

AlphaGo, from Google's DeepMind, made history today with its historic 4–1 defeat of Go world champion, Lee Sedol. Prior to the five-game match, many Go experts, including Mr. Lee himself predicted that the machine would be defeated 5–0 or, if it did well, 4–1. The result was quite the opposite with Mr. Lee managing just one win. This is both a shock for Go players, and represents an achievement in AI that many had not expected for at least another decade. Games, and in particular abstract strategy games like Go, chess and draughts have been a staple of AI research since its inception.
