It might surprise you, but copy-paste coders have always existed, LLMs are just making them more obvious, like "vibe coding". I don't use AI code assistants, but I can see why they could be valuable autocompleters in contexts where the user is knowledgeable.

It also makes me shudder to think of people who know just enough to compile and fix glaring mistakes, but largely trust the overall AI output. As if commercial software quality hasn't gone downhill enough these days.
