Fame is easy to acquire; impact is much more difficult.

My interest is not data, it's the world. And part of world development you can see in numbers. Others, like human rights, empowerment of women, it's very difficult to measure in numbers.

To get away from poverty, you need several things at the same time: school, health, and infrastructure - those are the public investments. And on the other side, you need market opportunities, information, employment, and human rights.

Fame is a dangerous thing. It's what the post-industrial society wants. They want fame and many followers on Twitter. But to really make the world understandable, that challenge is remaining.
