Abstraction Before Expansion
Systems often become expensive because they preserve more of reality than the problem requires.
Before increasing scale, we ask whether the problem can be represented more precisely. Can raw data be replaced by the essential information it contains? Can a physical process be studied through a faithful model? Can repeated computation be avoided? Can complexity be removed without removing capability?
A strong abstraction discards what is irrelevant while preserving the behavior that matters. It makes systems easier to understand, test, reproduce, and improve.
Expansion should not be the first response to difficulty. Better representation should come first.
