I don't think there is anything mysterious about lift. We can model it very well, we have precise equations that predict the exact results (though we can't solve them) and we know where these equations come from.

The fact that I do not understand the equations doesn't mean there is anything mysterious behind it.

There might be some artistry with regards to actually designing the aerodynamic shapes. We have no way of finding the best possible shape yet, this is largely a process of trial and error (though nowadays it can be automated with simulation without actually having to go through building physical model).
