AlphaGo wins again. DeepMind's AI has beaten Chinese world number one Ke Jie

In March last year, Google's DeepMind artificial intelligence completed an historic victory. Its AlphaGo system beat world Go champion Lee Sedol in a five-game contest of the famously complex board game. Not content with defeating one of the world's best players four games to one, in one of the most challenging board games to exist, the firm can now add another victory to its tally. Ke, who has been the top-ranked Go player for the past two years claimed last year he would never lose to a "cold machine." The night before the event, Ke wrote on Weibo that "the advancement of AI has far exceeded our imagination" but added he would never play it again after this week and said he "cannot feel its passion and longing for the game of Go".
