Sure, but understanding you need to have 5 vertices to make a pentagon isn't exactly high-brow.

Certainly not compared to making a Unix kernel from scratch.

I don't think high-brow / low-brow is a useful framework for understanding these models. They are good at certain things and bad at others and those don't correspond neatly to what a human finds easy and hard.
