I've also heard tell of some human professors having learned their academic knowledge and skills from other human professors, and then for some reason surpassed them.
When you finish reading "The Feynam Lectures" you feel unstoppable but then you open a problem book and youre stomped because youve just picked up someone elses mental model.
A good professor holds your hand just enough for you to build your own mental model and doesnt just regurgitate his own model. [0]
