The world's richest man pulled Microsoft out of his butt. All Bill Gates exploited was a line of 0s and 1s as long as a piece of string. Now Microsoft employs 118,000 people. Number six on the rich list, Mark Zuckerberg, created Facebook out of less than that. All Mark had was a dumb idea that all the stupid people want to tell every stupid thing about their lives to all the other stupid people. Current net worth of the person with that dumb idea, $11.2 billion.
