Go world champion Lee Sedol is retiring from the game of Go, stating that AI now dominates the famously complex board game.

"With the debut of AI in Go games, I've realized that I'm not even at the top even if I become number one," Lee told Yonhap.

Lee plans to play at least one more game, scheduled for January, 2020 against an AI called HanDol, developed by NHN Entertainment Corp. in South Korea.

Lee will be given an advantage in the game. HanDol has already defeated 5 top players.

"I wanted to play comfortably against HanDol as I have already retired, though I will do my best," he said.

Lee played against DeepMind's AlphaGo AI agent in 2016 in a series of heated matches. He ultimately lost to 1-4 to AlphaGo, but remains the only human to have beaten the program.
