> The key question is /why/ air moves faster on one side, and once you get away from the misconception of same time, I've never heard an intuitive argument.

Since the air follows a curved surface instead of straight ahead, you could perhaps apply your intuition for centrifugal force. Momentum sort of pulls the air away from the surface.

I’m not even sure this explanation is wrong.

That's interesting.

Counterpoint: A wing with the opposite curvature would work too, just much less efficiently. Your explanation has an element of truth, but an element of untruth. It'd take more analysis to tease them apart.
