Sanjay Gupta: (on innovations he has encountered that are making a difference) There are so many examples out there. I did have a chance to see first hand the One Laptop Per Child organization that Nicholas Negroponte put forward. It is bold and forward thinking, and a colleague of Negroponte's even used the analogy of comparing these computers to vaccinations. They are, after all, life-making tools. The laptop project also encourages literacy...which of course has health benefits too, since people are able to share health information.
