I think our perspective is that: software design has always had a subjective element to it. There's never been a "right" way to design a system, there are always trade offs that have to be made that depend on things like business context etc.
To that extent, most engineers probably still want to be part of that decision making process and not just let agents make all the high level decisions, especially if they're responsible for the code that ultimately gets merged
Most of human review I see of AI code is rubber stamping at this point, the volume is too big for human to keep up. What used to take Developers a few days to do is taking a few hours so PR volume is higher and human reviewing can't keep up.
