How do you refute your manager? Not only are they now biased to the answer, but without their own aesthetic (experience), it will cost you double: once to try the AI solution, and then another to try your version.

Suppose you're wrong versus the machine; they will think you are less consistent, even though every problem context carries its own nuance.

Having to, in good faith, try both avenues every time sounds exhausting.

You're assuming the manager will dictate the design/work, without feedback. Maybe I've been lucky, but I've never seen this in a technical setting, unless the manager was actually contributing to the technical work. The sorts of managers that micromanage and dictate like that don't last in technical environments, because they limit the teams technical ability to their own, and their ideas never make it past technical meetings/design reviews when others are involved.
