To my experience, AIs can generate perfectly good code relatively easy things, the kind you might as well copy&paste from stackoverflow, and they'll very confidently generate subtly wrong code for anything that's non-trivial for an experienced programmer to write. How do people deal with this? I simply don't understand the value proposition. Does Google now have 25% subtly wrong code? Or do they have 25% trivial code…
We all have probably 25% or more trivial code. AI is great for that. I have X (table structure, model, data, etc) and I want to make Y with it. A lot of code is pretty much mindless shuffling data around.
The other thing is good for is anything pretty standard. If I'm using a new technology and I just want to get started with whatever is the best practice, it's going to do that.
If I ever have to do PowerShell (I hate PowerShell), I can get AI to generate pretty much whatever I want and then I'm smart enough to fix any issues. But I really don't like starting from nothing in a tech I hate.
