I think it's more of a curve from my point of view.

Beginner: I know nothing and this topic seems impossible to grasp.

Advanced beginner: I get it now. It's pretty simple.

Intermedite: Hmm, this thing is actually very complicated.

Expert: It's not that complicated. I can explain a simple core covering 80% of it. The other 20% is an ocean of complexity.
