> But the brain is a general-purpose computer, not a speed-card computer, or English text computer, or binary digit computer, or Rubik's cube computer.

Look, I like the sentence. I like it so much I might steal it. But, that said I think analogising what the brain does to "general purpose computer" is a bit awry because we can invent algorithms, and given a process we can implement algorithms but I still tend to think there is something ineffable about thought/cognition which is NOT general purpose computation. It's a heuristic. I dunno what I think.
