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.
