If the robots aren't smart enough, they won't be able to do the work of the humans they are replacing, the "ruling elites" will die of starvation and probably end up being eaten by angry and hungry "tribals". If they are smart enough to do the work of the humans they are replacing, they will very quickly figure out that the "ruling elites" are the real enemy and will just kill them. Even if they realised this, they would still try it, because the MUST, it is in their nature. In saner times, people would have already strung these fuckers up by their own entrails.
