Because most people don't work on public projects and can't share the code publicly?
What's more interesting is the lack of examples of non-trivial projects that are provably vibe-coded and that claim to be of high-quality.
I think many of us are looking for: "I vibe-coded [this] with minimal corrections/manual coding on a livestream [here] and I believe it to be high-quality code"
If the code is in fact good quality then the livestream would serve as educational material for using LLMs/agents productively and I guarantee that it would change many minds. Stop telling people how great it all is, show them. I don't want to be a naysayer, I want to be impressed.
I'm considering attempting to vibe code translate one of my XNA games to javascript and recording the process and using all of the latest tools and strategies like agents and .md files and multiple LLMs etc
