Google will fulfill its mission only when its search engine is AI-complete. You guys know what that means? That's artificial intelligence.

I don't know about you, but I don't want Albert Einstein to be my pilot. I want great flying professionals that are allowed to, easily and quickly, take control of a plane.

Artificial intelligence would be the ultimate version of Google.

So we originally expected to make about 35 gigawatt hours at the cell level [solar] and about 50 gigawatt hours at the module or pack level. Now we are expecting to do about 150 gigawatt hours in the same volumetric space as the original design.

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

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.
