We would expect Elon Musk to be a champion of artificial intelligence. After all, it is the cornerstone of the autonomous driving system known as Autopilot that is featured in Tesla automobiles. But he has been warning about the potential dangers of AI since 2014, when he called it the “biggest existential threat” to humanity ever known. How can someone be a champion of new technology he finds so potentially dangerous? Easy — Musk is not constrained by conventional thinking. His ability to see not only both sides of a coin but also the edge and what's inside is legendary.
