My main problem with it is that it leads to very rigid thought structures devoid of curiosity or contextualization: The belief that the map is the terrain; that the universe is static, predetermined and discretely categorized under conveniently human terms; that scientific knowledge is either divined or standardized by a class of bureaucrats; that things are sorted over a “rank” of lesser to greater according to a direction towards objective progress.
It also generally sucks out a lot of the “fun” of learning about the world (though I understand sometimes taxonomy/categorization _can_ be fun in its own right).
As an example, grammar only really “clicked” with me when I was already in college: I was finally able to see it outside of the “prescriptive memorization hell” that I was subjected to in school, and instead perceive it under descriptive terms of Computer Science.
