If we measure the electrochemical activity of the whole cortex, we find wave-like patterns. This shows that brain activity is not local but rather that activity constantly moves from one part of the brain to another."

Not looking very charitable to the bottom-up, neuron machine view.

The same description would apply to a computer. Information moves around and it is distributed over many transistors and magnetic domains.



Let me bounce an idea of your statement here. Is there a constraint on the software that can run on a computer related to the functions that those transistors and magnetic domains can implement? Is this not a form of interaction between hardware and software?

Sure, a program to calculate f(x) has to be compiled differently depending on the computer. Some early computers even used trinary instead of binary. But assuming it's general purpose computer then it is always possible to translate a program from one computer to another so that they calculate the same function (except for possible space limits).
