February 2023. Andrej Karpathy — original OpenAI researcher, ex-Tesla AI director — posted this: "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." He wasn't prescribing a methodology. He was describing what he was already doing. And when someone with his background says he's forgetting that the code exists — that's worth paying attention to.
