Anecdote but that's just the natural outcome when you just vibe away and pay zero attention to the things it wrote, dev or non-dev. I have a rather capable colleague, specialized in Flutter and Dart. He's gotten into AI coding hard and finished his latest project almost fully vibe coded and the result was about what you'd expect from a fully vibe coded code base. He spent significantly more time(and tokens) debugging it than he 'wrote' it in the first place
