content: They were both formidable given the permitted prep time. Each was about the level I would expect of a good high school student who had weeks to prepare. IBM cited 5 or so papers but failed to address its opponent's arguments, so lost fairly. Both argued rationally. IBM, which was assigned to support subsidies, naturally argued for compassion more at first. This led Natarajan to do the same in his rebuttal.    I would lose a debate with either one. I think it was a fair competition. One one hand prep time was very limited, which strongly favor's a computer's methods. On the other hand the material is very emotional, which favors a human. Creepy moment to remember: when IBM mispronounced "lived", proving itself utterly soulless.
