I mentioned von Neumann architecture in my original description so as to make the distinction as clear as possible between computer architectures and human architectures, but the analogy works just as well with what you call high-level languages (presumably something like Lisp or Haskell?). You really have to be precise about why you think high-level languages make a difference. I claim that the distance between high-level programming languages and human languages is quite great; humans find it natural to express and understand instructions in human languages, but to express them in high-level programming languages still requires significant training. Yea, we've attempted to create programming languages that are really close to human languages, but for whatever reason, those never became successful.
