My own theory is that we are in the middle of a dramatic and broad technological and economic shift in which software companies are poised to take over large swathes of the economy

Over the next 10 years, I expect many more industries to be disrupted by software, with new world-beating Silicon Valley companies doing the disruption in more cases than not.

There's no such thing as the middle class. It's absolutely vanishing.

The good news about building a company during times like this is that the companies that do succeed are going to be extremely strong and resilient.

No one should expect building a new high-growth, software-powered company in an established industry to be easy. It's brutally difficult.

Google is working on self-driving cars, and they seem to work. People are so bad at driving cars that computers don't have to be that good to be much better.

Rule 1: All rules can be broken. Many (ex-legal and ethical) should be. Most people won't.
