Don’t just follow the trend. You may have heard me say that it’s good to think in terms of the physics approach of first principles. Which is, rather than reasoning by analogy, you boil things down to the most fundamental truths you can imagine and you reason up from there.

It is despairing to consider that the cost and reliability of access to space have barely changed since the Apollo era over three decades ago. Yet in virtually every other field of technology, we have made great strides in reducing cost and increasing capability.

What most people know but don't realize they know is that the world is almost entirely solar-powered already. If the sun wasn't there, we'd be a frozen ice ball at three degrees Kelvin, and the sun powers the entire system of precipitation. The whole ecosystem is solar-powered.

I'm increasingly inclined to think there should be some regulatory oversight, maybe at the national and international level just to make sure that we don't do something very foolish.

You have to be pretty driven to make it happen. Otherwise, you will just make yourself miserable.

If we drive down the cost of transportation in space, we can do great things.

Don't be afraid of new arenas.
