True - but it did have the benefit of giving the majority of people who passed through it the same benefit of a baseline understanding of "things" - those with aptitude and talent (and time and privilege) could take that further and build upon those fundamentals.

Now however, if people are not even internalizing those fundamentals in order to even re-write things in their own words, using their own "mental model" (perhaps correct, sometimes not) - I fear they won't even develop "mental models" and abstractions...
