Watch out, Bill Gates: Jeff Bezos is gunning for your title. Bezos is now worth about $84.6 billion total, leaving him just $5 billion shy of overtaking Gates as the wealthiest person in the world. Bezos, 53, is focused on aggressively expanding Amazon, while Gates, 61, wants to give most of his money away. Gates created the Giving Pledge with investing guru Warren Buffett -- the fourth wealthiest person with $76.8 billion -- in 2010. More than 150 people have signed the pledge, but Bezos isn't one of them.
