Sorry, while you are right (approximately) at what neurons do for a living, this result in supremely smart behavior if you have 100 Billion of these predication recognition devices in your brain ... which you do. What you miss is that we have long known that we can compute pretty much everything we see human neural systems compute this way. (Including actions and verification of whole sentences and stories, or telling them. As well as inventing and doing math and learning, with difficulty, formal logic and physics. Let alone Von Neumann style computing.

This article does describe a lot of the historical antecedents of this realization. I am pretty sure Gary Marcus is up on this. Don't know about Chomsky.

Here is how the brain computes and we can account for every computation we can observe a brain performing with just a few hundred billion neural re-cognition units between your ears.
