Great companies are built on great products.

I do think there is a lot of potential if you have a compelling product and people are willing to pay a premium for that. I think that is what Apple has shown. You can buy a much cheaper cell phone or laptop, but Apple's product is so much better than the alternative, and people are willing to pay that premium.

I'm extremely confident that solar will be at least a plurality of power, and most likely a majority... in less than 20 years.

I feel very strongly that SpaceX would not have been able to get started, nor would we have made the progress that we have, without the help of NASA.

The rumours of the demise of the U.S. manufacturing industry are greatly exaggerated.

Facebook is quite entrenched and has a network effect. It's hard to break into a network once it's formed.

I always invest my own money in the companies that I create. I don't believe in the whole thing of just using other people's money. I don't think that's right. I'm not going to ask other people to invest in something if I'm not prepared to do so myself.
