We, The Infected

My hero, Elon Musk, imagines bringing things to life that I used to dream about when I was a kid, voluntarily sequestered in the basement of the Midland County court house (where the youth library was located), sitting in the stairwell reading science-fiction books. And finally, at the end of the day, catching a ride home with my grandmother (the librarian), head full of starships, electric cars, and supercomputers that circled the Earth doling out the collective wisdom of mankind.
EDIT: I love his answer at the end, when he is asked why he does the things he does, and he answers: "I just want to think about the future of mankind without feeling sad."
