Well in the robot form thats still a little ways off but in the daily life thats all ready here. When we have another power grid failure seeing that it really hasn't been upgrade to handle large solar flare up like the one in the 1800's. The scientist have said it is not if but when it will happen again, also when the grid goes down it would take many months if not yrs to get the grid up again. No power , no store open for supplies, no tv, no Internet, no fuel, no banks, no communication systems. All if these in a large part are control by computers in this day and age with out them we are just sent back to the 1500's. ah a good cowboy hat and horse and your good. lol
