Finding solace in defeat by artificial intelligence

Hui was the first professional Go player to face AlphaGo, Google's artificial intelligence system and the title of a new documentary by Greg Kohs that debuted last week at the Tribeca Film Festival in New York. By the time it faced Hui, AlphaGo had trained on 160,000 games recorded from top Go players, and then on 30 million more games it played against itself. "[I] do my best to protect human intelligence," Hui says with a smile, after helping to accomplish the opposite. The film crescendos to a five-game matchup between AlphaGo and Lee Sedol, one of the world's best Go players, in Seoul, South Korea, in March 2016.
