Its not. Mostly it is an argument that turing-completeness is too mathematical to be practical.

If there is any quantum effect either used directly or measured within our brains, it might provide a speed advantage.
That's what I was getting at with the temp. comment, as I suppose an oracle machine could theoretically be classical.
Roger Penrose is one of the more authoritative, for lack of other arguments, voices for humans being more capable than AIs. Still not sure if it implies an existence of God, a class of ability higher than Turing machine or something else.
Yes it does, it would mean that your brain can somehow exploit quantum gravity to turn itself into an oracle machine. How a wet blob significantly hotter than room temperature (in the superconductor definition) is supposed to do that I don't know.
