That's true. "Maintenance" is basically reduced pressing the fault reset button in 9/10 cases if the program is good. OTOH, "lights out automation" means there's no one required on the factory floor and your number of jobs is significantly reduced.
If you can fit your whole maintenance department into the control room then you have not increased jobs you have most definitely reduced them
