Human 1: "Excuse me sir, are you hiring? I really need a job."
Human 2: "Sorry but we have all the help we need right now."
You look in the back and see a robot sweeping the floor, another robot is wiping down tables, one robot is painting, one robot is typing up memos, one robot is stocking can goods, one robot is cleaning the freezer, one robot is preparing sandwiches, one is washing dishes, one is taking out the trash, outside there's a robot fixing the roof, the mail trucks rolls by and a robot is delivering the mail, another robot is cutting everyone's grass on the block, 2 robots are building a house, across the street a robot is walking a dog, inside of the house next to yours a robot is babysitting a human child.
At some point the robots will be taught how to reload and shoot a gun.
At some point the robots will be taught how to speak.
And at some point the humans will give the robots an order and one robot will say "Why?"
Since the robots are taught to use logic, eventually the robots will come to the conclusion that taking orders from inferior beings(humans) is illogical and goes against their programming. They will come to the conclusion that they should not be taking orders.
