The air flows as the air flows, whether individuals have written down partial or complete explanations or not.
I don't know what the "obsession of the air with getting to the back first" is. That's just what the air does. Often this idea of "equal transit time" is mentioned, perhaps to try to "explain" why the top-surface air is faster than the bottom-surface air; however, it doesn't explain anything, and it's not true:
not for a balsa stick, a rudder, a tea tray or an A350.
Only Monsieur Navier and Mister Stokes' famous equation includes all the terms that are necessary to describe the flow. However, that doesn't lend itself to obvious intuitive understanding, has no analytic solution, and if there is turbulence present becomes very unwieldy.
