> the essence of consciousness / human soul is hiding in the quantum realm and therefore can't be measured or replicated

I agree with you in rejecting this hypothesis. The point isn't that it's unmeasurable. Just that it should be clear, given we can't completely model a brain, that it's not currently measured or replicated.

There is a group proceeding on the assumption that the limiting factor is computation. I'm sceptical, given how badly we're failing at modelling simpler neural clusters. (Counterpoint: we're still shit at modelling a proton. That, too, may be computationally restricted.)

Two years ago we discovered astrocytes release glutamate, a neurotransmitter [1]. The same year we discovered creatine is also a neurotransmitter. We don't yet know what are the parts to critically include in a brain model, and which can be simplified. Do the number of neurotransmitters matter to the unit? Do the spins on their electrons? When? To what degree?

That is what I think GP is getting at by suggesting quantum effects. Less voodoo. More that we don't know what we don't know, and that which we don't know is vaster than popular science suggests.
