Our brains use quantum computation within each neuron [1].

> Turing completeness not necessary for creativity--not by a long shot.
This is by far a more extreme claim than the others in this thread. A system that is not even Turing complete is extremely limited. It's near impossible to construct a system with the ability to loop and branch that isn't Turing complete, for example.
>(In fact, humans are not Turing complete.)
Humans are at least trivially Turing complete - to be Turing complete, all we need to be able to do is to read and write a tape or simulation of one, and use a lookup table with 6 entries (for the proven minimal (2,3) Turing machine) to choose which steps to follow.
Maybe you mean to suggest we exceed it. There is no evidence we can.

An infinite tape. And to be Turing complete we must "simulate" that tape--the tape head is not Turing complete, the whole UTM is.
> A system that is not even Turing complete is extremely limited.
PDAs are not "extremely limited", and we are more limited than PDAs because of our very finite nature.
I know very well what it means to be Turing complete. All the evidence so far, on the other hand suggests you don't.

An IO port is logically equivalent to infinite tape.

You can trivially execute every step in a Turing machine, hence you are Turing equivalent. It is clear you do not understand the subject at even a basic level.
LOL. Such projection. Humans are provably not Turing Complete because they are guaranteed to halt.
