Unless IBM's Watson can do more than play Jeopardy!, Garry Kasparov sees it as little more than a complicated toy.

That's what the Russian world chess champion said when asked for his thoughts on last week's Jeopardy! contest between two champions, Ken Jennings and Brad Rutter, and IBM's new Jeopardy!-playing supercomputer. Kasparov reviewed the three-day contest and offered his initial thoughts exclusively to The Atlantic.

What else could a supercomputer do, Gary? How about play chess?
