On Dec. 13, 2018, Richard Branson stood in the Mojave Desert, eyes fixed skyward as he witnessed the culmination of a lifelong dream: His space tourism company, Virgin Galactic, had sent an aircraft into suborbital space. For Branson, the launch was not merely proof of concept for his latest business venture. It signaled that humanity was on the edge of a fundamental breakthrough. "Today we have shown that Virgin Galactic can open space to the world," he declared. Four days later, the prominent philosopher Todd May published a short article in the Stone, a philosophy series run through the New York Times opinion section. "Would Human Extinction Be a Tragedy?" asked readers to consider the possibility that the demise of humanity might be morally desirable.
