From my experience, AI-assisted development is not good at complex systems. If a feature or fix requires a lot of changes in different places, or if the business logic is complex and difficult to understand, then the AI usually, in my experience at least, doesn’t do a good job with it. And because the system is large/complex, you have to have a correct understanding yourself of how the system works if you want to know if the AI changes will actually work as expected, and what edge cases it addresses and omits.
