Which region will be less affected by the coming climate crisis: New Zealand or Alaska? Is Google really building Ray Kurzweil a home for his brain, and will his consciousness live through the transition, or will it die and be reborn as a whole new one? Finally, the CEO of a brokerage house explained that he had nearly completed building his own underground bunker system and asked: “How do I maintain authority over my security force after the Event?”

The Event. That was their euphemism for the environmental collapse, social unrest, nuclear explosion, unstoppable virus, or Mr Robot hack that takes everything down.

This single question occupied us for the rest of the hour. They knew armed guards would be required to protect their compounds from the angry mobs. But how would they pay the guards once money was worthless? What would stop the guards from choosing their own leader? The billionaires considered using special combination locks on the food supply that only they knew. Or making guards wear disciplinary collars of some kind in return for their survival. Or maybe building robots to serve as guards and workers – if that technology could be developed in time.

For them, the future of technology is really about just one thing: escape.

Thus, we get tech billionaires launching electric cars into space – as if this symbolizes something more than one billionaire’s capacity for corporate promotion. And if a few people do reach escape velocity and somehow survive in a bubble on Mars – despite our inability to maintain such a bubble even here on Earth in either of two multibillion-dollar biosphere trials – the result will be less a continuation of the human diaspora than a lifeboat for the elite.
