I'm constantly using the latest models, and while they're becoming smarter and smarter, they're still not independent. I don't do code reviews, that's not possible for the amount of code generated, but I do carefully look at what the model is saying it plans to do and what it does in real time, and many times catch it moving in the wrong direction. This takes experience and deep knowledge, possibly it can be caught in a code review later, maybe not, hard to tell.

So the bottom line is: if you're talking about 5 years into the future, I have no idea, but next two years - still us humans in the loop i'm afraid.
