When you already have $150 billion a year in revenues from the iPhone, it's very hard to come up with any new vertical that will sort of move the dial. And there's this sort of weird effect where the larger a company gets, the harder it is to come up with any new product that really moves the dial.

There's been a lot companies that have shown "zero to one" kind of growth in the computer, internet software age. Facebook and Google are zero to one companies. Apple's iPhone was the first smartphone that really works, and of course, then you scale it horizontally, but the vertical component was really critical. Space X would also be one.

The value of failure is greatly over-rated. It's a preposterous myth.

Technology is probably the single biggest driver of productivity gains for the developed countries. For example, I think it's much more important than free trade.

Value investors look at cash flows. If a company can maintain present cash flows for 5 or 6 years, it’s a good investment. Investors then just hope that those cash flows - and thus the company’s value - don’t decrease faster than they anticipate.

Since 1920, the vast increase in welfare beneficiaries and the extension of the franchise to women - two constituencies that are notoriously tough for libertarians - have rendered the notion of "capitalist democracy" into an oxymoron.

Moving first is a tactic, not a goal.
