But surely you must see that this is just a choice which happens to lie favorably for the argument but is otherwise arbitrary. You could write a language which expressed manipulations of the electrical fluctuations in the same way that DNA is a programming language which expresses manipulations of ambient signaling protein levels to operate our cellular computers. Or, taken another way, GLSL is a language which shares a lot of similarity with "functional" languages (despite its C like syntax)---and it certainly doesn't run on an x86 architecture!
