To me the billionaire space race is an obvious good. The resulting decline in launch costs, for instance, is nudging dreams of a multi-trillion-dollar orbital economy and space-based solar power a bit closer to reality. Of course, people who loathe billionaires and despise capitalism have attempted to frame the investments by people such as Jeff Bezos and Elon Musk as evidence of indifference toward what happens to their home planet. Hey, why should they care if climate change ravages the Earth, they can always hop the next star shuttle to the Red Planet and start over, you know?

It’s absurd reasoning — space-based solar power and orbital manufacturing would actually be good for the Earth’s environment, by the way — but we’re likely to see a repeat as the super-rich invest in longevity technology. MIT Technology Review reports that Bezos is supposedly among the deep-pocket backers of Altos, a Silicon Valley startup “pursuing biological reprogramming technology, a way to rejuvenate cells in the lab that some scientists think could be extended to revitalize entire animal bodies, ultimately prolonging human life.”
