Will be cold fusion to be able to power all these machines batteries.
The trade off more robots less need for people that will have lousy lives, less medical with robots better than doctors that can see through your body , cars, entertainment, housing and food and life span questionable. Other option less government and there stupid spending, wars, corporation controls wanting to replace humans, and foreign free loaders having too many kids on generational dole and organized crime and less robots to replace them.
