As it is now, with just the vague handwaving many managers are doing, people are hearing "You should reach for AI immediately anytime you get an input that you technically can paste into the AI" - so we can't be mad at them if they're just doing what they think they're being told to do.
Design docs on the other hand have been fully taken over by the slop machine. They all kind of look the same now, and give off that familiar "I didn't write it so you might as well not read it" vibe.
