Google super-computer can be beaten, claims human champion
Google's Go-playing program AlphaGo is not yet superior to people despite its 4-1 victory, human champion Lee Sedol said.
The week-long showdown between the South Korean Go grandmaster and Google DeepMind's artificial intelligence programme showed the computer software has mastered a major challenge for artificial intelligence.
"I don't necessarily think AlphaGo is superior to me. I believe that there is still more a human being could do to play against artificial intelligence," Mr Lee said after the nearly-five-hour-long final game.
AlphaGo had the upper hand in terms of its lack of vulnerability to emotion and fatigue, two crucial aspects in the intense brain game.
"When it comes to psychological factors and strong concentration power, humans cannot be a match," Mr Lee said.
But he added: "I don't think my defeat this time is a loss for humanity. It clearly shows my weaknesses, but not the weakness of all humanity."
He expressed deep regret for the loss and thanked his fans for their support, saying he enjoyed all five matches.
Mr Lee (33), has made his living playing Go since he was 12 and is famous in South Korea even among people who do not play the game. The entire country was rooting for him to win.
The final game was too close to call until the very end, when Lee resigned after five hours.
