C'mon folks. So many "expert opinions" and erudite references in these comments. The sciences of cognition, neurology, evolutionary psychology etc are all still muddling around trying to figure out how the human mind works. We're learning a lot about possible ways the mind might work from our observations of processes and outcomes of machine learning. It's a cool new paradigm to add to the mix. I really like the framing offered by the author. They're quite upfront about the fact that there's a lot of genetics involved. That all models are wrong but some are useful.
Why all the defensiveness? Whatever genetic aspects of our personalities and behaviours there are - there's still a pretty big component of just learning patterns. Language acquisition is like that. It's an innate thing but the languages we're exposed to as kids shape what patterns of language use we fall into.
