Sadly, being open minded doesn’t automatically make someone smart. But I’ve personally had only good experiences with metal fans, so I’m anecdotally primed to believe what you describe is not a very significant problem, or at least not more widespread than in the general population.
not that you should be copy pasting any significanct amount of code, but at least when you do you’re required to understand it enough to fit it into your program. LLMs just straight up camouflage the shit code by putting something that already fits and has no squiggly red lines beneath. Many people probably don’t bother reading it at that point.
