Do we know enough about how the Brain works to know it's a computer? Or, do we simply have no other model for the transformation of information? What about subjective perception ?

A computer is a system that can implement the whole of constructive mathematics, within its resource constraints. Cells and brains are in this category. Subjective perception takes place in a virtual world, generated by the computer. It's a simulated property, not a physical one.

"Cells and brains are in this category". How do we know that constructive mathematics can model the hardware it's built on ? Isn't there a recursion or incompleteness ala godel issue?

No, Gödel had shown a problem with the semantics of classical mathematics, to which constructivism is the alternative. A computer can in principle implement every other computer.

I don't know much about the distinction you mention, except in broad stroked, so I'd have to think on it. If a computer implements itself, it will always be left with a level of nesting it can't simulate without going up another level, but then it hits the same problem again.

To make sense of the Hard Problem, it helps to realize that you are not trying to reconcile experience and ground truth, but two different types of models that your brain is creating. You have to understand the nature of models.

Replying to @Plinz @AriKatz20 and
I don’t see why this helps. I buy that what we experience is our brain’s simulation. But why not a zombie simulation/model?
