If the brain is the answer, the question involves trillions of parameters. Clearly there's more to the brain than just size, but also clearly, the brain is big for a reason. In fact scale is one of the very few things we can say for certain plays a big role in the function of the brain. GOFAI notions of embedding grammars and knowledge webs are just guesses on faith—the evidence points precisely in the opposite direction—and don't really make much sense anyway.
