Bill Gates talks polio, WinFS, and cheeseburgers in Reddit interview

To promote his latest annual letter, Bill Gates, co-chair of the Bill & Melinda Gates Foundation—and, of course, founder of Microsoft—answered questions today in a Reddit Ask Me Anything interview.

The most important topics Gates discussed were related to the Foundation's work. Gates believes that, in spite of the efforts of the anti-vax crowd, the eradication of polio is less than six years away. After polio, the focus will be measles and malaria.

Gates also stressed the importance of investment into the development of energy sources that don't produce carbon dioxide.
