Well, he did search Google with the Jeopardy questions and showed that very often the answer to the question was Google's first result. I think that's not only indicative of the difficulty of the problem at hand, but also shows that Watson is no different than established A. I. systems such as search engines. I had never seen Jeopardy before (not being from the States) and expected the game to be slightly more challenging; too many clues are included to the question asked and they make it too easy to determine the type of the expected answer ("this" appears almost in every single question). All three players seem to know the answer to any given question, and it's just a game of who presses the button first.
