I wonder if the codebase will be understandable at all.

You can most often “get used” to a codebase because they authors tend to stick to the same patterns in many ways, and they are somewhat coherent across time. After a bit you can kinda guess in what file is a feature implemented etc etc.

Will this still be true with ai doing most of the work?

Claude is really good about documenting what it has done. I’ve also had some good luck with “I’m interested in this part of the codebase please explain it to me” And “this part is not working let’s diagnose” I’ve been doing a lot of productionization of nontechnical vibecoding. And I provide a lot of feedback on best practices (one of which is to ask “is this best practices for security and data protection?”)

That being said there’s no replacement for a real knowledgeable human software engineer.
