Google's Go-playing AI AlphaGo defeats China's Ke Jie, the world's no. 1 player. Anita Li reports.
Another victory for artificial intelligence over the human brain. The grand champion of one of China's most ancient and iconic board games throwing in the towel on Thursday in a man versus machine grudge match against an AI system powered by Google. It's the second victory over champion Ke Jie this week for AlphaGo making their final meeting in the best of three competition on Saturday essentially meaningless. In their first game, AlphaGo defeated the human master by just half a point. But Thursday's victory was far more emphatic, Ke Jie quitting before the match was officially over. After the game, he said this tought me a lot about Go and a lot about life He's now the second champion to bow to AlphaGo's supremacy after the Korean number one was defeated in 4 out of 5 games by the program last year. That contest got a lot of publicity in China but with the competition on home soil this year, there's a lot less online buzz. The games have been officially streamed live on Youtube, which is owned by Google. But Youtube has been blocked in China for years, along with all other Google platforms after the company refused to censor its search results.
