This is sometimes theme in science fiction as well. While for example Snow Crash was a bit cheesy in this regard (reprogramming human brains with special words and similar stuff), the language used plays interesting role in The Culture series as well. EDIT: I would also suggest that Lisp and Java are more different than any two human languages in history. And even then, they are both Turing complete.
