AskScientists - what is the significance of Watson's performance on Jeopardy?  Is this a man on the moon moment for AI, or a gimmick?

If it is a man on the moon moment is debatable.  The major significance of Watson's performance is the natural language understanding, and information search related to that.  To most, it will not seem like anything, but then again, we have been living in the world and learning language for years.  Computers don't have this ability.  

Watson needs to first understand the category of the question, and then in that context parse the question to get an idea of what it is asking.  It doesn't seem like much to us, its a baked in ability to the human mind.  For a computer to do this is quite a feat, and a very hard problem to solve.
