A human opponent answered as follows: "Eyser was missing an arm"—and Watson then said, "What is a leg?" Watson lost for failing to note it the leg was "missing." Try a Google search on "Gymnast Eyser." Wikipedia comes up first with a long article about him. Watson depends on Google. If a Jeopardy contestant could use Google they would do better than Watson. Watson can translate "anatomical" into "body part" and Watson knows the names of the body parts. Watson did not know what an "oddity" is however. Watson would not have known that a gymnast without a leg was weird. If the question had been "what was weird about Eyser?" the people would have done fine. Watson would not have found "weird" in the Wikipedia article nor have understood what gymnasts do, nor why anyone would care. Try Googling "weird" and "Eyser" and see what you get. Keyword search is not thinking, nor anything like thinking. If we asked Watson why a disabled person would perform in the Olympics, Watson would have no idea what was even being asked. It wouldn't have understood the question, much less have been able to find the answer. Number crunching can only get you so far. Intelligence, artificial or otherwise, requires knowing why things happen, what emotions they stir up, and being able to predict possible consequences of actions. Watson can't do any of that. Thinking and searching text are not the same thing. - https://edge.org/responses/q2015
