If you look at the history of technology over a couple hundred years, it's all about time compression and making the globe smaller. It's had positive effects, all the ones that we know. So we're much less likely to have the kind of terrible misunderstandings that led to World War I, for example.

The characteristic of great innovators and great companies is they see a space that others do not. They don't just listen to what people tell them; they actually invent something new, something that you didn't know you needed, but the moment you see it, you say, 'I must have it.'

People are good at intuition, living our lives. What are computers good at? Memory.

I've come to a view that humans will continue to do what we do well, and that computers will continue to do what they do very well, and the two will coexist, but in different spaces.

People assume that computers will do everything that humans do. Not good. People are different from each other and they are all really different from computers.

Your car should drive itself. It's amazing to me that we let humans drive cars... It's a bug that cars were invented before computers.

I've never met a person who does not want a safer world, better medical care and education for their children, and peace with their neighbours. I just don't meet those people. What I meet, over and over again, as I travel around, is that the essential human condition is optimistic - in every one of these places.

The rise of Google, the rise of Facebook, the rise of Apple, I think are proof that there is a place for computer science as something that solves problems that people face every day.

There is a science to managing high tech businesses, and it needs to be respected. One of them is that in technology businesses, leadership is temporary. It's constantly recycling. So the asset has limited lifetime.

The policy of America to deny visas to technically trained people in the U.S. and shipped to other countries, where they create companies that compete with America, has to be the stupidest policy of all the U.S. government policies.

I use Google+, and I find the quality of the comments are very sophisticated because there is more trust inside of Google+ than there is inside of Twitter and Facebook, for example.

I used to say that you'll have 10 IP address on your body... and it looks like that's going to happen through medical monitoring.
