I've just now read your article, "Could Quantum Brain Effects Explain Consciousness?"
Please understand that the "quantum mind" program did not originate with Penrose. Stapp and Lockwood preceded him, and so did I.
Moreover, I do not agree with many of the tenets of the Penrose-Hameroff model. The appeal to quantum gravity is a nonstarter for me, e.g.
On the other hand, I do agree with Penrose that strong AI is fatally flawed in respect of its emphasis on functional relations.
Those who disagree might ask themselves what the brain employs for the arguments of its functions -- i.e., what are the x's in f(x)?
Finally, as Dyson tells us, "There is nothing else except these [quantum] fields: the whole of the material universe is built of them."
The brain is presumably part of the material universe, yes?
And so just is a collection of quantum fields?_________
