I think you missed the point of my comment. BQP (i.e. "stuff that is efficiently solvable by a quantum computer") is almost certainly bigger than P (i.e. "stuff that is efficiently solvable by classical computers"). There was not even remotely anything in my argument that was claiming "only humans can be human" or "only humans can be intelligent" or anything like that (that would have been a silly claim). And nothing remotely related to claiming quantum effects have anything to do with human brains.
