I don't particularly like that essay because the author seems focused on the idea that "your brain is a computer" is a metaphor rather than a theory (see [1] for a more nuanced discussion).

The author correctly points out that past eras developed metaphors to explain how the mind might work based on the technological innovations they were familiar with, but I think there's a lot more nuance in the computational theory of the mind.

Namely that the notion of computation is much more abstract, and potentially more portable across disciplines, than some of the historical examples that the author of that Aeon piece brings up.

Anyway, obviously I don't have any real answers but for whatever reason the brain-as-a-computer theory rings pretty true for me and I've enjoyed reading essays and watching talks about the topic [2] [3].

I followed your links and ended up in this rather excellent essay:

One of the final points the author makes is that the brain might be a neural network made up of as many as 89 million neural networks.

That's a staggering concept.

If true, I wonder how anyone stays sane with that level of entropy in the system!

The "neural network of neural networks" thing is a bit of lavish exaggeration TBH, because a network of networks is just a larger network. The human brain has about 100tn synapses, which I think is a less obscure statistic to marvel about.
