These are not the people you expect to come to the rescue. Rock stars are designed to be shiny, shallow creatures, furloughed from reality for all time. Billionaires are even more removed, nestled atop fantastic wealth where they never again have to place their own calls or defrost dinner or fly commercial. So Bono spends several thousand dollars at a restaurant for a nice Pinot Noir, and Bill Gates, the great predator of the Internet age, has a trampoline room in his $100 million house. It makes you think that if these guys can decide to make it their mission to save the world, partner with people they would never otherwise meet, care about causes that are not sexy or dignified in the ways that celebrities normally require, then no one really has a good excuse anymore for just staying on the sidelines and watching.
Such is the nature of Bono's fame that just about everyone in the world wants to meet him--except for the richest man in the world, who thought it would be a waste of time. "World health is immensely complicated," says Gates, recalling that first encounter in 2002. "It doesn't really boil down to a 'Let's be nice' analysis. So I thought a meeting wouldn't be all that valuable."
It took about three minutes with Bono for Gates to change his mind. Bill and his wife Melinda, another computer nerd turned poverty warrior, love facts and data with a tenderness most people reserve for their children, and Bono was hurling metrics across the table as fast as they could keep up. "He was every bit the geek that we are," says Gates Foundation chief Patty Stonesifer, who helped broker that first summit. "He just happens to be a geek who is a fantastic musician."
And so another alliance was born: unlikely, unsentimental, hard nosed, clear eyed and dead set on driving poverty into history. The rocker's job is to be raucous, grab our attention. The engineers' job is to make things work. 2005 is the year they turned the corner, when Bono charmed and bullied and morally blackmailed the leaders of the world's richest countries into forgiving $40 billion in debt owed by the poorest; now those countries can spend the money on health and schools rather than interest payments--and have no more excuses for not doing so. The Gateses, having built the world's biggest charity, with a $29 billion endowment, spent the year giving more money away faster than anyone ever has, including nearly half a billion dollars for the Grand Challenges, in which they asked the very best brains in the world how they would solve a huge problem, like inventing a vaccine that needs no needles and no refrigeration, if they had the money to do it.
