Watson’s human competitors made Wednesday’s final Jeopardy! match more competitive, but, in the end, the IBM supercomputer came out on top—by more than $50,000.
Ken Jennings, who, along with Brad Rutter, made up the computer’s competition on three episodes of the game show beginning Monday, had a sense of humor about the drubbing.

Watson’s human competitors made Wednesday’s final Jeopardy! match more competitive, but, in the end, the IBM supercomputer came out on top—by more than $50,000.
Ken Jennings, who, along with Brad Rutter, made up the computer’s competition on three episodes of the game show beginning Monday, had a sense of humor about the drubbing.
“I for one welcome our new computer overlords,” the former Jeopardy! champion scrawled below the answer to the competition’s final question.

The victory made one group of people very happy.
The computer-science department at the University of Texas at Austin hosted viewing parties for the first two nights of the competition.
“People were cheering for Watson,” says Ken Barker, a research scientist at Texas. “When they introduced Brad and Ken, there were a few boos in the audience.”
Texas is one of eight universities whose researchers helped develop the technology on which Watson is based. Many of the other universities hosted viewing parties for the three days of competition as well.
Mr. Barker says he was blown away by Watson’s performance on the show, particularly the computer’s ability to make sense of Jeopardy!‘s cleverly worded clues.

But the computer did make a few mistakes along the way.
Most notably, Watson incorrectly wrote “Toronto” in response to a Final Jeopardy clue in the category of U.S. Cities. Both Mr. Jennings and Mr. Rutter returned the correct response, which was Chicago.
Mr. Barker says Watson may have considered U.S. to be a synonym of America and, as such, considered Toronto, a North American city, to be a suitable response.
Raymond J. Mooney, a computer-science professor at Texas, says Final Jeopardy is the Achilles heel of the computer.
“If it didn’t have to answer that question, it wouldn’t have,” he says.

Clues in that final round are often more complicated than others in the show because they involve multiple parts.
The phrasing of the question Watson got wrong included what linguists refer to as an ellipsis, an omitted phrase whose meaning is implicit from other parts of the sentence. The clue that tripped up Watson, “Its largest airport is named for a World War II hero; its second largest, for a World War II battle,” left out “airport is named” in the second clause.
Mr. Mooney says it will be some time before the average person will be using a computer with the capabilities of Watson, but he did see one potential immediate impact from the show.
Several new students showed up at the viewing parties and expressed interest in the technology.
“If this can spark the interest of more kids out there, then that would be great,” he says.
