Go humans: Lee Sedol scores first victory against supercomputer

Go grandmaster wins fourth showdown of five-match series against Google's artificial intelligence, AlphaGo

The rise of the machines came to a halt, temporarily at least, when the champion Go player Lee Sedol beat a computer program on Sunday to prevent a whitewash after losing the first three games.

AlphaGo, developed by the Google subsidiary DeepMind, has an insurmountable lead in the series, but Sedol's win restored some human dignity. Fans of the ancient Chinese board game cheered when AlphaGo quit after five hours and Lee was greeted by applause from journalists at the post-match news conference at a Seoul hotel.
