There are many more secrets in the world that are waiting to be found. The question of how many secrets exist in our world is roughly equivalent to how many startups people should start.

Rivalry causes us to overemphasize old opportunities and slavishly copy what has worked in the past.

Great tech opportunities happen only once.

In the developed world, technological progress means that you can have a situation where there's growth, where there's a way in which everybody can be better off over time.

My own answer to the contrarian question is that most people think the future of the world will be defined by globalization, but the truth is that technology matters more.

I'm always very excited about trying to do something on next-generation biotechnology and life sciences because I think if we can cure cancer or dementia, we can really make the future a lot better and I think these things are eminently doable.

One of the reasons I think people are increasingly nervous about U.S. debt is because they think that we are not actually digging ourselves out of the hole, but instead are digging ourselves into a deeper and deeper hole and will not be able to pay it back because we're not actually creating the new technologies that will enable us to pay back and the money somehow is not really being invested in the future or in progress.
