When we think about online learning, it's such 'early days.' Bill Gates is a wildly smart insightful guy. Yet, even a guy as smart and insightful as that, 30 years ago can say things like,'Who's every going to need more than 640K of memory?'

In the U.S., HBO is a very aggressive service.

Be brutally honest about the short term and optimistic and confident about the long term.

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.

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.

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