That's fairly counterintuitive to me. The easiest avenue for an AI to gain advantage over a human is reaction time and accuracy. E.g. an AI that reacts in microseconds will never be beaten on pure reaction by a human given that there's a floor of some 50-100msec for a human to be physically able to react to stimulus.

E.g. I remember early 3rd party Starcraft AIs would beat humans just by micromanaging certain nimble flying units.
