I don't know the full story, only that the fact air particles have to speed up over the top so they match up at the end is incorrect - one at the top, one at the bottom don't actually arrive at the end at the same time. There is something missing.
This is wrong. Lift is generated from pressure difference. This pressure difference is caused by air moving faster over the top of the wing. I have no idea what you're talking about with air particles matching up at the end.
I vaguely remember seeing a video that explained that how it's usually explained is wrong. That's what they're probably referring to. But it wasn't that we don't actually know how it works, just that the common simplification is not technically correct (which happens often with these things).
