South Korean “Go Master” Retires Due Invincibility of A.I. Competitors

Recently on PBS Frontline they actually featured Lee Se-dol taking on the A.I. computer and it was actually fascinating to watch. That is still the only time a human has beat an A.I. at the game Go:

South Korean Go master Lee Se-dol, who retired from professional Go competition last week after gaining worldwide fame in 2016 as the only human to defeat the artificial intelligence (AI) Go player AlphaGo, said his retirement was primarily motivated by the invincibility of AI Go programs.

“With the debut of AI in Go games, I’ve realized that I’m not at the top even if I become the number one through frantic efforts,” said Lee.

“Even if I become the number one, there is an entity that cannot be defeated,” he said in an interview with Yonhap News Agency in Seoul on Monday.

AlphaGo, built by Google’s DeepMind Technologies, won four of its five matches against Lee in March 2016, but Lee’s sole win in Game 4 remains the only time a human has beaten the AI player.

Reflecting on the historic Game 4 on March 13, 2016, Lee attributed his win to a bug in the AlphaGo program.

In the game, Lee’s unexpected move at white 78 developed a white wedge between blacks at the center. The apparently embarrassed AlphaGo responded poorly on move 79, suddenly turning the game in Lee’s favor. AlphaGo then declared its surrender by displaying a “resign” message on the computer screen.

Lee’s white 78 is still praised as a “brilliant, divine” move that offered a ray of hope to humans frustrated by AIs.
