LLMs also seem prone to making weird decisions that no human would have done. You can very quickly have a broad implementation - often with features that are great and that you didn't even know you wanted - but when you dig into the features, the weirdness reveals itself bit by bit. If you were developing by hand you would have used a sensible range for zoom from the start, but the LLM doesn't seem to work that way.

I suspect people saying "everyone will vibe code all their software" have never actually tried to vibe code a meaningfully complex application.
