Tech billionaires are buying up large bunkers

Survival of the Richest author Douglas Rushkoff published an expose
(https://archive.ph/wZ94t) the other day at The Guardian about how
the world's money-grubbing tech gurus are actively trying to build
themselves survival bunkers to weather the coming apocalypse that
they are helping engineer.
Rushkoff says he was recently invited to attend a secret gathering
of five tech billionaires somewhere out in the desert, during which
he was asked all kinds of questions about how to build the best and
most secure underground bunkers.
These billionaires' biggest concern seemed to be about how to ensure
that the security forces they hire do not turn on them once everythin
hits the fan. Demonstrating their total lack of empathy - meaning
these tech billionaires are sociopaths - they simply could not
comprehend that treating people right now will serve them much better
than trying to forcefully ensure their own survival at the expense
of everyone else.
"How do I maintain authority over my security force after the event?"
asked the CEO of a brokerage house, recognizing that Rushkoff knows
a thing or two about survival and the logistics surrounding its success.
"The event. That was their euphemism for the environmental collapse,
social unrest, nuclear explosion, solar storm, unstoppable virus,
or malicious computer hack that takes everything down," Rushkoff
explains in his piece about the primary focus of these tech
billionaires.
It turns out that the bulk of the private meeting was centered around
the security issue and how to keep security forces paid, fed, and
happy so that they continue to protect the very tech billionaires who
destroyed the world in the first place.
While one of them suggested simply locking their food behind
combinations that only they knew, at least one of the tech
billionaires proposed forcing their security teams to wear
disciplinary shock collars to ensure their compliance.
Another brought up the idea of building non-human robots to serve as
guards and workers for their underground, dystopian "paradises" that
they expect to survive in once society collapses.
Rushkoff, who describes himself as a "Marxist media theorist," tried
to reason with the men about how a more pro-social approach centered
around partnership and solidarity is the most promising for preserving
"our collective, long-term challenges." It turns out that none of
them wanted to hear any of this.
"The way to get your guards to exhibit loyalty in the future was to
treat them like friends right now, I explained," Rushkoff writes
about what he said to the tech billionaires. "Don't just invest in
ammo and electric fences, invest in people and relationships. They
rolled their eyes at what must have sounded to them like hippy
philosophy."
In the end, Rushkoff says he came to the realization that billionaire
tech moguls "are actually the losers" in this whole scenario. They
will likely be the first to go once all bets are off because We the
People see them for who they are.
"The billionaires who called me out to the desert to evaluate their
bunker strategies are not the victors of the economic game so much
as the victims of its perversely limited rules," Rushkoff says.
"More than anything, they have succumbed to a mindset where 'winning'
means earning enough money to insulate themselves from the damage
they are creating by earning money in that way. It's as if they want to
build a car that goes fast enough to escape from its own exhaust."
"Yet this Silicon Valley escapism - let's call it The Mindset 
encourages its adherents to believe that the winners can somehow
leave the rest of us behind."
