If I break some source code by messing with it, I know what happened. I might even learn from it. Now if npm breaks it, or Claude breaks it, a developer might not even know what was broken. He's talking about that kind of thing, not the resilience of code to take random character deletions. IT is very much non-specialized compared to older disciplines. It's so young. Every single one of us is still a jack of all trades in some degree. You're relying on the "don't roll your own crypto" popular quote to drop the mic. That's misguided. This advice comes from an argument of strength by numbers, not anything related to abstractions. It tells me you don't understand it.
