This. The hacks, shortcuts and bugs I saw in our product code after i got hired, were stuff every LLM would tell you not to do.

Amen. On top of that, especially now, with good prompting you can get closer to that better than you think.

LLM's at best asymptotically approach a human doing the same task. They are trained on the best and the worst. Nothing they output deserves faith other than what can be proven beyond a shadow of a doubt with your own eyes and tooling. I'll say the same thing to anyone vibe coding that I'd say to programmatically illiterate. Trust this only insofar as you can prove it works, and you can stay ahead of the machine. Dabble if you want, but to use something safely enough to rely on, you need to be 10% smarter than it is.
