but you should hold in the back of your head a realization that your understanding of said ecosystem and the compiler is limited. Likely always will be, as there are multiple not stupid people working on it, and there's one of you.

It happened to me that I knew how to do X (and then did it) which had been boldly declared as impossible to do by the resident senior expert. I knew it not because I liked those minutiae, just was willing to dig to the bottom when solving some problem earlier. I dunno, but it's likely that both geeks who just absorb niche and arcane knowledge to feel superior and bone-minded resident experts are equally bad (and sometimes, rarely, but still, they are the same guy).
