That is what vibe coding is. The tweet says "It's not too bad for throwaway projects" but that does not limit the definition, it only limits the advisable application of it.
Vibe coding is “Forget the code even exists; it mostly works for throwaway stuff”. That is clearly not what this person wants.
You can’t pick up vibe coding and then complain that it’s behaving as described or that it isn’t giving you something that wasn’t promised.
Don't disagree at all. It was never promised that LLMs could do what he's trying to do. But just because he's holding it wrong doesn't mean that he's not holding it.
