For some reason, the word "robot" does not sit right with the most of us. We have this set idea that one day, the robots will take over the planet and destroy the human race. I am trying to guess where this fear comes from. Could it be Stephen Hawking's repeated predictions? And still, we are afraid that if the robots become too smart, the chances of a bad ending for us, the humans, increase.
