It's official: The supercomputer Watson really, truly, creamed the competition. In tonight's final Jeopardy! showdown between Watson and human competitors Ken Jennings and Brad Rutter, the computer took them down. The computer walked away with $77,147 — almost three times as much as Jennings, the second-place guy. "I, for one, welcome our new computer overlords," quipped Jennings. [NYP]
