Mars is the only place in the solar system where it's possible for life to become multi-planetarian.

The primary means of energy generation is going to solar. It will at least be a plurality, and probably be a slight majority in the long term.

What I'm trying to do is to maximise the probability of the future being better.

I think it's important to reason from first principles rather than by analogy. The normal way we conduct our lives is we reason by analogy. [With analogy] we are doing this because it's like something else that was done, or it is like what other people are doing. [With first principles] you boil things down to the most fundamental truths…and then reason up from there.

When people really understand it's do or die [and] if we work hard and pull through, it's going to be a great outcome; people will give it everything they've got.

We need to be super careful with AI. Potentially more dangerous than nukes.

People work better when they know what the goal is and why. It is important that people look forward to coming to work in the morning and enjoy working.
