Tech leader Elon Musk is known for sounding the alarm bells on the risks of artificial intelligence. Musk has said that he believes that AI will soon manipulate social media if it hasn't already -- a concern that pales in comparison to his previous predictions of a future humanity governed by an intelligent machine dictator. A year ago, he told Recode Decode that the relative intelligence ratio between such a dictator and the rest of humanity would resemble the ratio between a person and a cat. The great Musk doesn't stand alone in fearing the risks of AI gone wrong. Stephen Hawking and other researchers have said that intelligent machines could become very dangerous.
