From what I understand, the challenge is the following: Even though we know precisely how to calculate the lift generated by a wing, all attempts to reduce those equations and their predictions to "ELI5" arguments leads to incorrect explanations. Basically: We can explain aircraft lift to a college student, but not to a 5 year old. Or, we can explain aircraft lift using equations, but not using informal arguments.
