To recap: [1] Random person on Hacker News personally "knows" a billionaire. [2] Billionaire renounced U.S. citizenship without having to realize any significant capitals gains. [3] Billionaire doesn't own a car. He just spends his time touring Africa, solving AIDS or malaria like Bono or Bill Gates. [4] Billionaire has a secret lair, from which he dresses up in a costume and fights crime by night. I could be making some of these up. I started to have serious doubts right at [1], and completely got off the train by [2].
