By 2030 over 2 billion jobs will disappear.

At Silicon Valley, I'm extremely sympathetic to the revolutionary response. I not only agree with it emotionally. I agree with it practically. And the only thing I disagree with is, I don't think Donald Trump is that. Trump is blow it up for no good reason at all. You want to actually do revolution with a target, with an idea, with building a new system.

I think the randomness by Donald Trump's governing, by tweeting, sloganeering, attacking, will create great chaos in the entire market. I think people will have difficulties in predicting the future. I think capital will recede.

There are two reasons [ business people are not publicly anti-Donald Trump ], one is well-intentioned, which is the classic kind of American notion. We want to be inclusive, we want to have our shareholders, our employees, our customers, whether they are Democrat, Republican, Green or Libertarian, to feel comfortable with how we're doing business. And so that tends to be apolitical. People say, "No, no, I just simply shouldn't get involved in politics."

World-changing startups need to be premised on accurate contrarian theories.

Companies hire a lot during boom times because they're trying to adequately accelerate into the future.

We have made a huge amount of progress over the last 50 years by enabling trade, by enabling kind of collaboration and learning. And actually, in fact, when you look at your average 30-year-old today, they're much better off than a 30-year-old 20 years ago, 30 years ago, because of progress in technology and health care and all the rest of this.
