...assuming that modelling the physical structure of the brain is the only way to model its functions.

Building a "NN with similar capability as the brain" is not modelling its physical structure. The assumption is not made.

Let's define the terms. What does it mean "with similar capacity"? As far as I understand xvilka was taking about the number of artificial neurons required to model a biological neuron times the number of biological neurons in the human brain. It is modelling its physical structure (on a neuronal level).

You vastly overestimate how much we know about how our brains work.

Look up the neural correlates replication crisis, and e. g. the "dead salmon" study by Bennett et al.

		That is we have unknowns that might increase or decrease estimates of computational demands of a functionally equivalent ANN. Not everything that happens in the brain contributes to information processing.
