Yet Deep Blue’s victory left the world’s artificial intelligence community unimpressed. That was because the machine performed its feat merely by crunching numbers faster than any other computer had managed before. Its enormous processing power enabled it to predict a game’s possible course up to 30 moves ahead, while its clever programming allowed it to work out which of the millions of possible moves would strengthen its position best. On its own, all that Deep Blue could do—and do brilliantly—was the mathematics. What it could not do was devise its own strategies for playing a game of chess.
