From my experience AI works well as a alternative to Stack overflow or searching for the answer, or rewording the solution to be easier understood.

AI is good at rewording the documentation of code so if the documentation isn’t good or written by someone who’s lived in the sauce for too long, AI can be very very helpful.

But you need to know how to code, and not just blindly copying the output, you need to understand what it’s doing and make sure that it fits your code base.

I have touched C in ages so AI helped me get to grips with it again when working in a project. But it didn’t write my code, I did. Which made fixing bugs a lot easier when they were found or reported.
