A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey the orders given to it by human beings, except where such orders would conflict with the first law. A robot must protect its own existence, as long as this does not conflict with the first two laws. Although Asimov wrote these laws as fiction in the 1940s, before robots existed, they reflect ongoing concerns that some people have about robots. Useless and unnecessary, humans are gradually pushed aside.
Fear of machines taking control is nothing new.
A Space Odyssey are a few. However, if robots do develop consciousness, they may also develop a conscience and choose to be kind to their human creators.
