Free Will and Airplane Wings

So I recently had a debate with one of the premier Artificial Intelligence authorities in the world regarding free will. His name is Eliezer Yudkowsky, and as you can probably imagine, he's a smart guy.

He too is an absolute determinist, but he's a full compatibilist. He employed an interesting analogy in trying to make his argument. He believes that claiming we are just atoms bumping into each other (and therefore not really making decisions) is like claiming that airplane wings don't allow airplanes to fly, but instead it's "just a bunch of atoms".

His point, obviously, is that both are true.

I have much to say about this, but I'd like to see what your thoughts are. ::
