“You don’t choose your passions, your passions choose you.” So begins Jeff Bezos, then the world’s richest man. It is Thursday, 9 May 2019 and he is on stage in front of a dimly lit audience, somewhat reminiscent of Apple’s famous keynote events. He will present his long-term vision not only for the future of some of his business interests, but for all of humanity, spanning hundreds of years into the future, and defining millennia after that. It is a dream he has held on to for decades longer than the past two spent building Blue Origin, the aerospace manufacturer and suborbital spaceflight company he founded in 2000.
