Friday Video: Think you have nothing to fear from robots? This one cheats at Rock, Paper, Scissors

Thanks to Isaac Asimov, a lot of people think that robots are actually infused with his Three Laws of Robotics:


  1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
  2. A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
  3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

Bullfeathers. It’s Science Fiction, heavy on the fiction. There are no positronic brains (yet) despite what you saw on “Star Trek: The Next Generation” and there’s nothing mandatory about putting Asimov’s three laws into any given robot.

Case in point: This robot from the University of Tokyo that cheats at playing rock, paper, scissors. It waits to see which choice you’re going to make and then quickly chooses and executes a winning move faster than you can detect the cheat.

Shake in fear, puny human.
