The actual central point is that the brain requires conditioning via experience. That shouldn't be controversial, and I can't decide if the general replies here are an extended and ironic elaboration of his point or not.

If you never memorize anything, but are highly adept at searching for that information, your brain has only learned how to search for things. Any work it needs to do in the absence of searching will be compromised due to the lack of conditioning/experience. Maybe that works for you, or maybe that works in the world that's being built currently, but it doesn't change the basic premise at all.
