When robots decide to kill

CZECH WRITER KAREL CAPEK'S 1920 play R.U.R. (Rossum's Universal Robots), which famously introduced the word robot to the world, begins with synthetic humans-the robots from the title-toiling in factories to produce low-cost goods. It ends with those same robots killing off the human race. Thus was born an enduring plot line in science fiction: robots spiraling out of control and turning into unstoppable killing machines. Twentieth-century literature and film would go on to bring us many more examples of robots wreaking havoc on the world, with Hollywood notably turning the theme into blockbuster franchises like The Matrix, Transformers, and The Terminator.
