Vibe-coding as originally defined (by Karpathy?) implied not reading the code at all, just trying it and pasting back any error codes; repeat ad infinitum until it works or you give up.

Now the term has evolved into "using AI in coding" (usually with a hint of non rigor/casualness), but that's not what it originally meant.

AI assisted coding/engineering becomes "vibe coding" when you decide to abdicate any understanding of what you are building, instead focusing only on the outcome
