good vibes all around

I was reading Andrej Karpathy’s original post, https://x.com/karpathy/status/1886192184808149383, on vibe coding. And yesterday, first time I tried VS Code, in order to try Codeium, as my first touch of edit assist which the early GitHub Copilot I test drove before did not have.
