What a terrific accomplishment IBM Watson is! The managers and engineers on that team must be proud to see how well the system did on Jeopardy. I think it's great for someone besides Google to demonstrate such innovation, and to do so in a way that the average person can get excited about.
We shouldn't have been surprised to find out that as impressive as Watson is, the system nevertheless is not yet perfect. For instance, Watson's designers didn't anticipate the need to receive and interpret answers from other players.
This is an exciting development and I'm curious to see which direction IBM will go from here.
