“Google DeepMind’s Go-playing AI has done it again. After beating top player Lee Sedol at the ancient Chinese game in 2016, the AlphaGo AI has been secretly taking on more of the world’s best players – and beating them. For the last few days, an unknown player called “Master” has been thrashing players on an online Go platform called Tygem. Master beat the world number one player Ke Jie twice, and won 50 out of 51 games that it played, drawing the one it didn’t win outright due to an internet connection time out. There was a lot of speculation about who could be behind the Master account, with many people suspecting that artificial intelligence was making the moves but unsure who could have developed it.”
