He seems to be arguing that you shouldn't handicap the computer by removing one of its advantages, but they've already handicapped the humans by removing lots of their advantages: at least in the parts I've seen, there have been no audio or visual clues, and it's my understanding that Watson gets the text of the question over the wire, not even having to OCR the same text that the humans get to read while waiting for Alex to finish reading the question.

I'm an IBMer and I think Watson has been extremely impressive, but as a Jeopardy fan it gets tiresome to see Watson win the race to the buzzer this often.

Finally, I'm hoping that tonight features more of the wordplay-heavy clues that I hear were present on the first night (why oh why was that on Valentine's Day???), because that is the element that excited me most when I heard about the challenge.
