From an interview by Brad Stone for Bloomberg Businessweek:

One of Google’s convictions is that bringing Internet connectivity to less-developed countries can lead to all sorts of secondary benefits. It has a project to float broadband transmitters on balloons. Can bringing Internet access to parts of the world that don’t have it help solve problems?

Gates:

When you’re dying of malaria, I suppose you’ll look up and see that balloon, and I’m not sure how it’ll help you. When a kid gets diarrhea, no, there’s no website that relieves that. Certainly I’m a huge believer in the digital revolution. And connecting up primary-health-care centers, connecting up schools, those are good things. But no, those are not, for the really low-income countries, unless you directly say we’re going to do something about malaria.
