The tendency to attribute consciousness to the quantum is one I find very grating. What makes the human brain any less mechanical if quantum mechanics dictate the firing of neurons rather than electrodynamics? Why does the wave nature of subatomic systems mean that an artificial tongue would suddenly be able to subjectively experience taste? It always reads to me as very wooy, and any amount of drilling leads to even more questions that seem to take the ideas further from reality.

I think the largest case for consciousness being a mechanical system is the fact that we can interface with it mechanically. We can introduce electricity, magnetic fields, chemicals, and scalpels to change the nature of peoples experience and consciousness. Why is the incredible complexity of our brains an insufficient answer and that a secret qbit microtube in each neuron is a more sound one?
