I think since the mechanisms are different we should arrive at a distinction between:

organic thinking (I.e. the process our squishy human brains do)

and mechanical thinking ( the computational and stochastic processes that computers do ).

I don't think the substrate defines the nature of the thinking, but the form of the process does.

It is entirely possible to build mechanical thinking in organic material (think Turing machines built on growing tissue), and it could also be possible to build complex self-referential processes simulated on electronic hardware, of the kind high-level brains do, with their rhythms of alfa and beta waves.
