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

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.

To our knowledge, life exists on only one planet, Earth. If something bad happens, it's gone. I think we should establish life on another planet-Mars in particular-but we 're not making very good progress. SpaceX is intended to make that happen.

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.

You want to be extra rigorous about making the best possible thing you can. Find everything that's wrong with it and fix it.

The problem is that at a lot of big companies, process becomes a substitute for thinking. You're encouraged to behave like a little gear in a complex machine. Frankly, it allows you to keep people who aren't that smart, who aren't that creative.

I wouldn't say I have a lack of fear. In fact, I'd like my fear emotion to be less because it's very distracting and fries my nervous system.
