I think he's saying that the brain is not just the genome. What you see as an adult brain also represents a host of environmental factors. Since these environmental factors are complex, so then is the brain.

Yes you could probably use some machine learning algorithm to build a brain with the input of a video feed. But this says relatively little about how the brain actually develops in nature.

That's just the thing. It makes a big difference whether we're talking about a (not necessarily human) brain in general, or a specific, particular brain. Artificial intelligence research is concerned about being able to find any brain design it can understand and work with, while neuroscience is concerned with the particulars of human brain anatomy and often the specific brains of specific people.

Also, I'd be kinda hesitant to dismiss anything that involves being able to build a brain as "saying relatively little" about anything brain-related.

Thanks for the clarification. You're right that artificial intelligence and neuroscience are two different fields.
