> Serious vibe coders will ingest an entire codebase into the model, and then use some system that automates iterating.

People who do that are <0.1% of those who use GenAI when coding. It doesn't create anything usable in production. "Ingesting an entire codebase" isn't even possible when going beyond absolute toy size, and even when it is, the context pollution generally worsens results on top of making the calls very slow and expensive.

If you're going talk about those people you should be comparing them with private jet trips (which of course are many orders of magnitude worse than even those "vibe coders")
