In March 2014 the enigmatic founder of Tesla Motors, Elon Musk, travelled to London to announce the sale of his company’s Model S electric car in the UK. After the launch, I asked Musk if he knew that Larry Page, the founder of Google, had recently said he would leave his fortune – more than $30bn – to him. What, I asked, would he do with the money?
“I’d use it to build a city on Mars,” he said. Then he shrugged, grinned, and stared at me in an odd, intense way.
