I'd invert that. You can't complain, whine, or plot social solutions in response to getting assigned tasks by a robot. There's a lower mental load in response to getting a task, since you don't have to worry about how your response to task assignment gets interpreted by your boss.
And I'd invert that: unlike a robot (unless programmed to be cruel), you can see your boss getting off on commanding you to do ridiculous shit. With a robot, you can just think, "Well it's just a brainless robot." With a boss, you think, "Why doesn't that glib asshole use their brain... or better yet, let me use mine?"
(Pardon if my language seems salty; "asshole" and "shit" are actually popular technical terms when dealing with the domain of bosses.)
