It's mid-afternoon on a Friday at SpaceX headquarters in Hawthorne, California, and three of Elon Musk's children are gathered around him – one of his triplets, both of his twins.
Musk is wearing a gray T-shirt and sitting in a swivel chair at his desk, which is not in a private office behind a closed door, but in an accessible corner cubicle festooned with outer-space novelty items, photos of his rockets, and mementos from Tesla and his other companies.
Most tellingly, there's a framed poster of a shooting star with a caption underneath it that reads, "When you wish upon a falling star, your dreams can come true. Unless it's really a meteor hurtling to the Earth which will destroy all life. Then you're pretty much hosed, no matter what you wish for. Unless it's death by meteorite." To most people, this would be mere dark humor, but in this setting, it's also a reminder of Musk's master plan: to create habitats for humanity on other planets and moons. If we don't send our civilization into another Dark Ages before Musk or one of his dream's inheritors pull it off, then Musk will likely be remembered as one of the most seminal figures of this millennium.
