Google's Deepmind AI beats Go world champion in first match
The "AlphaGo" program forced its opponent, 33-year-old 9-dan professional Lee Sedol, to resign three and a half hours into the first of their five-match battle. While Deepmind has defeated a Go champion before, it's the first time a machine has beaten a world champion.
