Stone Age. Bronze Age. Iron Age. We define entire epics of humanity by the technology they use.

When you grow up, as I have, in the shadow of Steve Jobs, Bill Gates and others, success is defined as the total global transformation of a market. To achieve that, you need low prices and an attractive offering. It's about trying to make a positive impact on a big scale.

I'm an HBO subscriber, and I watch a bunch of great shows on HBO.

Broadcast TV is like the landline of 20 years ago.

Technological revolutions are very hard to predict. My favourite example is someone in 1850 taking care of horses as a farrier. They would have said, "Look, horses have been part of human existence for 5,000 years. We are horse people. It's permanent." But all of a sudden, the internal combustion engine comes along and, with it, oil fields and automobiles, which basically replace the horse completely. So we often have these long periods of stability and then a sudden inflection point.
