Silicon Valley billionaires buy underground bunkers preparing for the apocalypse

Billionaires in the world's tech capital Silicon Valley are reportedly preparing for the apocalypse by buying underground bunkers, guns, ammo and motorcycles. Fearful that artificial intelligence will displace so many jobs that there will be a revolt against those responsible for the technology, the are entrepreneurs readying themselves for doomsday like scenarios. Reid Hoffman, the co-founder of the professional social network, LinkedIn, told The New Yorker that he believes more than 50 per cent of billionaires in the Californian tech hub are preparing for the worst. "I own a couple of motorcycles. I have a bunch of guns and ammo. I figure that, with that, I can hole up in my house for some amount of time," he said.
