A top computer scientist told us the games that artificial intelligence can't win

Google's DeepMind artificial intelligence team is making history. Its AlphaGo program is up 2-0 on Lee Sedol, one of the top Go players alive. This is the first time a computer has beat a human champion without a handicap. While there will be three more games between Sedol and AlphaGo, the victory suggests that Go is the latest game that computers are outwitting people in. Checkers fell in 1994, Chess in 1997, and Jeopardy in 2011. "It there's a social component with players playing together, it's not clear," Littman says.
