A true bubble is when something is overvalued and intensely believed. Education may be the only thing people still believe in in the United States. To question education is really dangerous. It is the absolute taboo. It's like telling the world there's no Santa Claus.

I do think Bitcoin is the first [encrypted money] that has the potential to do something like change the world.

I think somehow people should be encouraged to think about a very long time horizon and I think this is true for businesses, it's true for governments and it's true for people doing things in the non-profit sector.

In a world where wealth is growing, you can get away with printing money. Doubling the debt over the next 20 years is not a problem.

Now it’s either about technology that doesn’t work or about technology that’s used in bad ways. The anthology of the top twenty-five sci-fi stories in 1970 was, like, ‘Me and my friend the robot went for a walk on the moon,’ and in 2008 it was, like, ‘The galaxy is run by a fundamentalist Islamic confederacy, and there are people who are hunting planets and killing them for fun.’

You want to be the last company in a category. Those are the ones that are really valuable.

I do tend to think that things that have incredibly long time horizons often do involve market failures.
