The definition seems to have pretty rapidly moved to 'used an AI coding assistant in some capacity'.
I wonder if maybe some people have been trying to jump on the "I have also tried vibe coding" train without being willing to hop as far as the term initiator defined it.
I definitely still stick to the "Vibe Coding is when you don't read / grok the code" definition.
Another commenter said these people only read half of Karpathy's tweet - I disagree. I don't think they read it at all, have heard the phrase, and are using it with reckless abandon.
GitHub copilot which is mostly single line completions isn't "vibe coding".
I think vibe coding also entails some "what it did was so simple, I didn't bother to check it".
