For me it was never about money, but solving problems for the future of humanity.

I think we should be very careful about artificial intelligence. If I had to guess at what our biggest existential threat is, it's probably that. So we need to be very careful...With artificial intelligence we're summoning the demon.

I think there are more politicians in favor of electric cars than against. There are still some that are against, and I think the reasoning for that varies depending on the person, but in some cases, they just don't believe in climate change - they think oil will last forever.

It's not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it's a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.

I'd like to dial it back 5% or 10% and try to have a vacation that's not just e-mail with a view.

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 first principles] you boil things down to the most fundamental truths…and then reason up from there.
