Elon Musk: Genius or jerk?

Elon Musk, the California-based entrepreneur behind the Tesla electric car, the SpaceX commercial rocket venture and several other wacky start-ups, made a fool of himself with his attempt to intervene in the Thai cave rescue and subsequent Twitter spat, but there’s no doubt he’s an original thinker and a remarkable businessman.

If the futuristic Tesla is a fine feat of technology, what’s more impressive is that the company is not only still in business after 15 years without turning a profit and having lost at least $3.5 billion since 2015, but that its market capitalisation, at $52 billion, is bigger than Ford’s at $42 billion. Tesla built more than 100,000 cars last year compared with 6.6 million by Ford worldwide.

My man in California with a close eye on the tech scene says the deal that really showed Musk’s mettle was his purchase for Tesla in 2010 of the huge former General Motors-Toyota factory at Fremont.
