most processes will never be set up to be eliminated for exactly the reason you state, nobody has the time or the manpower to set it up effectively. there is some stuff called human layer where it is intended to have a human person step in at certain places, increasing efficiency and getting rid of the chaff, that where it will probably be most implemented and it will only be a productivity booster not a job replacer. like using a nailgun vs using a hammer.
