So far as I'm aware, the Gates Foundation does nothing in regard to the world's biggest problem, which is aging. Aging kills the most people, causes the greatest amount of suffering, causes the greatest loss of wealth and capital, falls most heavily on the poor without access to palliative medical technologies, etc, etc.<p><a href="http://www.fightaging.org/archives/2002/12/death-is-an-outrage-1.php" rel="nofollow">http://www.fightaging.org/archives/2002/12/death-is-an-outra...</a><p>You'll see a number of mainstream foundations in the Methuselah Foundation lists, and those also support the SENS Research Foundation, working on the basis for ways to reverse the cellular and molecular damage that causes aging. The Gates foundation isn't there:<p><a href="http://mfoundation.org/?pn=donors" rel="nofollow">http://mfoundation.org/?pn=donors</a><p>But that's not entirely surprising: from the beginning, the Gates Foundation has been a very traditional Big Philanthropy operation. Wealth does not grant vision. Where there is innovation or stepping away from the norms it is of the incremental type, with none of what Peter Thiel calls "radical philanthropy". Is this is a criticism of Gates? Sure. But it's equally a criticism of everyone else. The Gates Foundation is doing what most people think Big Philanthropy should do. The blind spot for aging is near universal.
