Many people thought a computer wasn't supposed to be able to beat a top master at the ancient Chinese game, Weiqi, for at least another 10 years. But AlphaGo, an artificially intelligent system(人工智能系统) designed by Google, made it. It easily beat Lee Sedol last year, one of the best players in the world. It challenged the world's top players to show how much progress it had made over the past few years.

In the late of May, 2017, AlphaGo appeared in China and played against 19-year-old Ke Jie in Wuzhen, China. He is No. 1 player now in the world. However, the result wasn't out of people's expectation. He lost the matches. Though Ke Jie tried his best and he once saw the victory just a step away, he lost his best chance when he became excited.

At the press conference(新闻发布会) after the match, Ke Jie was interviewed by the reporters.He said he had realized how powerful AlphaGo was, and it was getting perfect. When a Chinese reporter asked him in English, the reporter spoke so fast that the interpreter(口译员 ) couldn't catch him. Ke Jie got kind of angry and told him that it was unnecessary for two Chinese to speak English. The reporter apologized to him and offered to ask him for a coffee.

The cat and mouse game is over, but the challenge between man and robots will still go on.
