- how many neurons must we rub together to get a basic Turing Machine?
I think the more neurons you put together, the less like a Turing Machine your system will look. The firing of each has a stochastic component that combines in some way (I don't exactly know how, but probably something less than purely additive) with its neighbors. The uncertainly is too high to be a Turing machine; its the reason you can't throw a dart the same way each time.
- ...if there ever was a viable avenue of pursuing the relationship between consciousness and materiality, this is it. Don't you agree?
I'll give a qualified "yes" to this question. Here's the qualification: I think it is wise to look for a connection between consciousness and materiality in some conceptual, perhaps mathematical (perhaps purely philosophical, although I find that much less appealing), framework. Whether its this particular one, I can't say, because I don't understand his logic entirely yet. But I certainly grant that I like his approach. I think the manner in which consciousness is broached in neuroscience is one of the great scientific farces of the day (and its also one of the most romanticized, unfortunately). The attempts to atomize consciousness to statements like "your occipital cortex merges image for you", or "your amygdala gives you 'fight-or-flight' instructions" make me sick to my stomach. There is not one sensible statement that grants faculties to the brain itself, yet that is the norm in neuroscience. We, as individulas, are conscious beings, whether purely material or material-metaphysical. I hope one day we can discover a conceptual framework in which this idea can be interpreted, but I know beyond doubt that it will never be discovered by a traditional neuroscientist.

The 'just so' science. I share your revulsion regarding this matter. An entirely chance phenomena? Consider the socio-political dimensions ..... (and its also one of the most romanticized, unfortunately).
