Innovation is moving at a scarily fast pace.

I really do think cancer will largely be a solved problem. I think most of the infectious diseases like malaria - our foundation is very involved - once we're finishing polio eradication, then starting up this malaria eradication, and getting that done as fast as we can.

Certainly I'll never be able to put myself in the situation that people growing up in the less developed countries are in. I've gotten a bit of a sense of it by being out there and meeting people and talking with them.

We're responsible for the creation of the PC industry. The whole idea of compatible machines and lots of software - that's something we brought to computing. And so it's a responsibility for us to make sure that things like security don't get in the way of that dream.

Windows 8 is key to the future, the Surface computer.

I feel certain that the personal computer is as revolutionary in terms of the way it will change the way we work, learn, and entertain ourselves as any of these previous advances.

I believe in innovation and that the way you get innovation is you fund research and you learn the basic facts.
