Lee Sedol

Korean 9-dan Go professional, 18 world championships, "the Roger Federer of Go". He faced alphago in March 2016 expecting to win 5-0 or 4-1, lost the first three games, then won game 4 with move 78, a "God move" AlphaGo rated at about 1 in 10,000 for a human that exposed its superhuman-blind-spots. That remains humanity's only win against it. The match became "playing for the human"; afterwards: "he showed me something... I see the world different... maybe it's beautiful."
