> AI-assistance will be particularly helpful and powerful in large codebases (think 100k+ lines of code). It’s simply impossible for any human being to fully understand that amount of code in detail… Even PROs/craftsmen who enjoy writing the code manually can’t make such claims. Our context windows are simply not large enough.

This is a false premise because LLMs do not understand code. Yes, they may be capable of ingesting your entire massive codebase and spitting back out relevant stuff, but they don't actually understand any of it. Vibe coding is just "copy/paste from StackOverflow until it works" on steroids.
