But in short a demonstration today IBM's Jeopardy-playing supercomputer, a whiz by the name of Watson, thoroughly bested two talented human contestants. IBM has been working on this artificial intelligence project for years to prove that a computer can be programmed to understand conversational speech and wordplay. In today's demo, Watson seems to have proved the point: it started out on a roll in the category "Chicks Dig Me," about women and archaeology. The real man versus machine face-off (in which the same contestants compete for a $1 million prize) will be taped tomorrow, and aired in February.
