Elon Musk wants to get to Mars before we nuke ourselves

Elon Musk is bullish on humanity’s chances getting to Mars and even building a city, but he’s not super confident about our odds here on Earth. During a wide-ranging interview with GQ, the SpaceX CEO described planetary colonization as a coldly practical endeavor. “You back up your hard drive... maybe we should back up life, too?” As for how he plans to do it, he said that SpaceX will announce more concrete plans as soon as it’s ready. “Before we announce it, I want to make sure that we’re not gonna make really big changes ... I think it’s gonna seem pretty crazy, no matter what.”
