With tech bros investing in vast underground homes to shield them from future horrors, a slew of ‘bunker-buster’ dramas like Paradise and Silo are asking: do they know something we don’t?

Sam Altman’s got one – although Mark Zuckerberg’s is, apparently, bigger. Peter Thiel’s is described as “mega” and located in New Zealand. These days, a doomsday bunker (or, in Elon Musk’s case, an “apocalypse resort”) is de rigueur for any self-respecting billionaire – enough to make you wonder if they know something we don’t.

A slew of recent dramas suggests that we are fascinated by such impressive underground real estate. Most audacious is Paradise on Disney+, in which tech-billionaire Samantha Redmond (Julianne Nicholson) funds a staggeringly elaborate building project under the not-so-subtle codename “Versailles”. Unlike Clive Owen’s Andy Ronson in A Murder at the End of the World, saving a few hand-picked individuals isn’t enough for this girl-boss-cum-tech-bro. Instead, Redmond has gone a step further, building “the world’s largest underground city”, an ersatz all-American suburb, accommodating 25,000 people while a climate catastrophe plays out above their heads.
