Thou Shalt Not Build Killer Robots

Humanity has been dreaming bad dreams about killer robots and murderous artificial people for more than 200 years now. When the recurring nightmares started, the possibility was ludicrous. On a dark and stormy night, Mary Shelley woke up screaming,  "Argghhh! Luigi Galvani made a frog's leg twitch with electricity! Frankenstein's monster is coming!" It's not so wacky anymore, is it? The tech is rapidly catching up with Mary's nightmare. And the top AI scientists who aren't perfecting sexbots are now relentlessly working along these lines. When robots and androids actually start killing us, we'll have nobody but ourselves to blame.
