All the talk last week has been of Google DeepMind playing, and beating, the world champion of Go. I don't know the game Go well, but I have read that it is so complex that it was previously thought a computer could not beat a top human player. Until now of course, as Google Deepmind's AlphaGo has used Artificial Intelligence (AI) to finally beat a person - South Korea's Lee Se-dol - who turned pro at the age of 12 and has won 18 world championships!
