There is a simple "explanation" of wing lift, though: the wing pushes air down, it applies downward force on air masses. This is a trivial consequence of Newton's third rule and the facts that a) there's gravity, b) airplanes don't fall from the sky.

If you want to know what exactly is happening to the air around the wing you need fluid dynamics of course.

I don't know if we'll get any such "conservation of X" principle from the AI world, but that would be pretty cool.
