The Global Fund is a central player in the progress being achieved on HIV, TB and malaria. It channels resources to help countries fight these diseases. I believe in its impact because I have seen it firsthand.

You can go overboard in how quickly you might expect new technologies to transform people's lives. But I very much believe the way software is used, the way information gets distributed, will be dramatically different within 10 years. There is fire to go with all this smoke.
