I didn’t think I would see this take on HN of all places. You can’t appreciate Higher Topos Theory before spending a decade’s worth of effort in pure math - does that make much of Modern Algebraic Geometry “garbage”?

Math doesn't exist to be appreciated. Literature has literally no other application.

EUV litography machine is incredibly complex and I would have to learn for decades to meaningfully understand it, yet I can appreciate it knowing very little (of it and in general).
