My point is that a human nervous system is MUCH slower than Watson's equivalent. It is probable (don't know, but it seems likely) that it is more variable, as well. As such, under the current rules, Watson has an overwhelming advantage. If all the contestants know the answer before the question is "read", then Watson will consistently beat the humans to the buzzer. The only hope for the humans is that Watson hasn't decided an answer by the time the question is finished being "read".

Without some way to account for the fact that the human nervous system CANNOT beat Watson to the buzzer on any sort of consistent basis, the game is far less compelling than it should be.
