I feel like he’s learnt the wrong lesson from this. There is a vast gulf between letting an LLM loose without oversight in a language you don’t know and starting from scratch yourself. There’s absolutely nothing wrong with having AI do the first draft. But it actually has to be a first draft, not something you blindly commit without review.

> “Vibe coding”, or whatever “coding with AI without knowing how to code” is called, is as of today a recipe for disaster, if you’re building anything that’s not a quick prototype.

But that’s what vibe coding is. It’s explicitly about quick throwaway prototypes. If you care about the code, you are not vibe coding.

> There's a new kind of coding I call "vibe coding", where you fully give in to the vibes, embrace exponentials, and forget that the code even exists. […] It's not too bad for throwaway weekend projects, but still quite amusing. I'm building a project or webapp, but it's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.

He’s basically saying that vibe coding is a disaster after his experience doing something that is not vibe coding.
