The revolutionary breakthrough will come with rockets that are fully and rapidly reusable. We will never conquer Mars unless we do that. It'll be too expensive. The American colonies would never have been pioneered if the ships that crossed the ocean hadn't been reusable.

Internet TV and the move to the digital approach is quite revolutionary. TV has historically has been a broadcast medium with everybody picking from a very finite number of channels.

The internet offers immense possibilities for encounter and solidarity. This is something truly good, a gift from God.

We've actually set the tech priorities driven off what we want to build for customers and what they're asking us to solve, and that's how it's going to be, and that is a cultural tension even today because we actually want some of both, we want ownership.

So, what I think, sometimes a pure tech company can underestimate is the importance of culture, the importance of a purpose.

In technology, we need revolutionary change, not incremental change.
