>> Another victory for artificial intelligence over the human brain. The grand champion of one of China's most ancient and iconic board games throw in a towel on Thursday in a man versus machine grudge match against an AI system powered by Google. I'm Reuter's Anita Lee in the town of Wuzhen in eastern China, where the AlphaGo AI system has just gone two for two in a battle against the number one goal player in the whole country.
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 game was officially over.
After the game he said, playing with AlphaGo gave him a new understanding of the game, even a new understanding of life. He's now the second champion to bow to AlphaGo's supremacy after the Korean number one was defeated in four out of five games by the program last year.
