I've been posting recently how I refactored a few different code bases with the help of AI. Faster code, higher quality code, overall smaller. AI is not a hammer, it's a Lathe: incredibly powerful but only if you understand exactly what you're doing otherwise it will happily make a big mess.
if you have to understand exactly what you're doing, why not just... do it?
but, as an engineer, i have to say if it works for you and you're getting quality output, then go for it. it's just not for me.
