For years, chess was considered not just a game, but a spiritual exercise as well, an activity that tapped into an essential element in the human mind.
Then reigning world champion Garry Kasparov was defeated by IBM’s Deep Blue computer in 1997.
But years after computers rose far above humans in chess playing capability, its Asian counterpart, Go, held out. Go grandmasters soundly defeated computers, who couldn’t use “tree-branch” computation to map out all the possible moves on the Go board, which is much bigger, and thus contained more possible moves, than a chess board.
This is history, you saw it folks.
