I'd say this is similar to working with assembly vs c++ vs python. Programming in python you learn less about low level architecture trivia than in assembly, but you learn way more in terms of high level understanding of issues.

When I had to deal with/patch complex c/c++ code, I rarely ever got a deep understanding of what the code did exactly - just barely enough to patch what was needed and move on. With help of LLMs it's easier to understand what the whole codebase is about.
