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 important that we attempt to extend life beyond Earth now. It is the first time in the four billion-year history of Earth that it's been possible, and that window could be open for a long time - hopefully it is - or it could be open for a short time. We should err on the side of caution and do something now.

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

There are some important differences between me and Tony Stark, like I have five kids, so I spend more time going to Disneyland than parties.

I think there are too many smart people pursuing internet stuff, finance, and law. That is part of the reason why we haven't seen as much innovation.

Silicon Valley has evolved a critical mass of engineers and venture capitalists and all the support structure - the law firms, the real estate, all that - that are all actually geared toward being accepting of startups.
