You really don't get the issue. Give real developers pull requests with 10, 100, 1000 and 10000 lines of changed code. I promise you, 100% that the quality on the latter two pull requests will be abysmal. No matter how good you are as a developer, you can be the best of the best, after a few hundred lines of code you're unfamiliar with you'll overlook obvious issues.
And let's be honest, most developers will try to quickly get it done, read over it, hit the approve button and go back to their own work. This is how it works in the real world.
A small pull request with 10 or at most 100 lines will get a lot more scrutiny where developers actually have the mental capacity to think and reason about the code and its context.
If you let AI write a full system, or even a full module at once, spitting that code out, you'll get large pull requests. Too large to do a meaningful review. It's like if I threw you a pull request right now for a software you're not familiar with and it's 2000 lines of code. How well do you think you'll do?
You can't have your cake and eat it too. The entire point of AI would be to off-load the development work. You write a specification, throw it into the magic AI box, then get a working code base out.
Why the hell would you invest ten times the amount of organization work to break every feature down into small human sized parts? The AI doesn't need bite sized tickets like humans do, you can throw a complex 100 page specification at it and get out working code an hour later. But you'll get out 100k lines of code at once in that case.
You're treating the AI like a junior developer, give it tiny tickets it can work on, then let a human review the work. The human will do badly because they have no context (they'd have to read the entire specification first, then read the pull request, then try to reason about code that a machine wrote). Reviewing code is always more difficult than writing it, the writing part is easy.
