> Brain is essentially a biological Turing-complete processing unit
How do you know that?
Some would answer, "well, everything in the physical universe can be simulated by a Turing machine, so also the brain" but that would be begging the question.

Currently it is just a highly plausible conjecture, not a formal proof. However, I think I can prove it. But should I?
And even if the connectome can be modeled as a graph, the dynamics on the graph could be totally alien to us. It might be computable by a Turing machine. But it also might involve some not computable process we can't imagine. Perhaps it involves fundamentally unknown physics. (I consider the last option to be quite likely. I think rather few actually entertain the idea that physics as we understand it today could give rise to consciousness. But here we are.)
