80% is good enough for like the bottom 1/4th-1/3rd of software projects. That is way better than an offshore parasite company throwing stuff at the wall because they don't care about consistency or quality at all. These projects will bore your average HNer to death rather quickly (if not technically, then politically).
Maybe people here are used to good code bases, so it doesn't make sense that 80% is good enough there, but I've seen some bad code bases (that still made money) that would be much easier to work on by not reinventing the wheel and not following patterns that are decades old and no one does any more.
I think defining the places where vibe-coded software is safe to use is going to be important.
My list so far is:
* Runs locally on local data and does not connect to the internet in any way (to avoid most security issues)
* Generated by users for their own personal use (so it isn't some outside force inflicting bad, broken software on them)
* Produces output in standard, human-readable formats that can be spot-checked by users (to avoid the cases where the AI fakes the entire program & just produces random answers)
