IBM really wants to beat humans with their computers. In the past, they created Deep Blue
which was able to defeat the human Chess champion. Now, they developed Watson, an information retrieving machine which is intended to defeat the human Jeopardy champion.
Watson has already accomplished this by defeating Ken Jennings, the current Jeopardy champion in a practice round. The machine is likely to defeat Jennings in the real match later this year.
The video below explains more about Watson and the motivation behind making such a computer (besides the obvious taking over the world).
