Well clearly the brain isn't infinite, but nor is any Turing Machine we implement. When we say something like C is Turing complete, we don't mean that any correct implementation can compute what a TM can compute, because no implementation is finite. Eventually both the stack will be exhausted and malloc() will fail; there's a finite amount of state available on any concrete hardware. My point being that that seems to be such a trivially true statement - conveying no information - so that we must understand the sentence to mean something else; that it can compute what a TM can compute, up to some arbitrary limit related to available state. So, would you say that the brain isn't Turing complete either?
