As someone who was both a human Jeopardy! contestant, and who has also developed AI software, I have to throw my loyalties with Watson. He crushed his human opponents. Perhaps my pleasure in his win was increased by seeing the champs shaking their heads in frustration as they obviously knew the clues but lost to Watson’s amazing buzz-in technique time and time again, much like my own feelings when I was on the show.
Overall, I am astounded at the progress that has been made in the codification of general knowledge and natural language processing. Watson was simply amazing.
