They could have some “quiet quit”. Robots with mundane jobs that don’t get enough stimulation or rewards end up spending most of their time parked in a corner or closet. When they do move, they move at ~50% their design speed.
Some robots could steal food from the refrigerator; some could spray strong perfumes; some could chat up the management then go fuck up a staff person’s work to make them look bad.
The possibilities are endless.
That’s because it’s all placebo effect. That doesn’t make acupuncture effective. Anything you can make someone believe can be just as effective.
