I don't think there's a clear distinction between vibecoding and AI assisted coding because there's black boxes EVERYWHERE no matter how knowledgeable you are. Compilers assist me to not have to think about machine code. Web libraries and frameworks assist me to not care about networking details. AI, vibe coding or not, is all just another thing to assist the user by reducing distractions.

I think it's valuable for developers to understand more of their code rather than less, but who cares to precisely label how much they understand? If they're happy with the passing tests, comfortable making it public, and others want to contribute, then that's what matters.
