Forgive me if i'm wrong but i think that the essence of this article goes back to (let's wear our sicp hats) the difference of functions and procedures. Procedures are performed intrinsically a lot of times unaware of their functional view. Both can produce the same results. As for the article itself i find it quite annoying cause it just tries to shove so many things to the reader that it obscures the essence. Is it really needed to go from sea slugs to neurons to hyperbolic geometry to atomic theory and the solution of the Schroedinger equations to holograms and Fourier transforms to make your point?
