With great technological power comes great political responsibility. As the boss of Tesla, the world’s most valuable carmaker, and SpaceX, the world’s second-most valuable unicorn, Elon Musk is the stuff of business legend. Mr Musk wants to help stabilise the climate (hence his focus on electric cars) and to establish an outpost of civilisation on Mars (hence the rockets, one of which sent four astronauts to the International Space Station on October 5th). To help fund the Mars effort, SpaceX launched Starlink, a huge constellation of satellites that provide internet access to isolated users. Should be worried about Elon Musk’s superpowers?
