My previous homeowner was also a vibe maintainer! The difference that I see in this is that the LLM is reasonably at 'expert' level for many of these things. If I sit down with Stevie Wonder and ask him to help me write a song, the resulting song is probably going to be pretty good. Stevie also knows by experience lots of things to avoid, and is intuitively going to help me avoid them unless I instruct him specifically to make a poor choice.

I think there are likely opportunities too to have models or system prompts that cater or adapt to the experience level of the person it's working with. "As you interact with the user, determine their relative level of knowledge and experience. If they seem to be relatively inexperienced with software development, be much more aggressive in helping to warn them about and avoid common pitfalls, bad architectural decisions, and security issues."

I suspect it's probably going to enable a lot of poor quality stuff, but it also may to some degree raise the floor of what's being produced at the same time.
