"A man who crosses the street must be careful not to be hit by a car, even if the car is an automatic vehicle without a driver, because the car is stronger than a man. We should be afraid of devices that function in a dangerous way for us. The robot will become such a device if we manage to equip it not so much in intelligence as in mechanisms imitating the effects of a certain human functionality. I mean equipping robots with mechanisms that function in a similar way to consciousness of existence and the instinct of self-preservation of a human being. I do not mean to say that the device will be conscious, but that its behavior will be similar to the behavior of a rational unit, such as a man aware of his existence. The machine will not receive consciousness, but it will behave as if it did."
