I do not know what got me interested in technology. What was very clear to me very early on was that I was not interested in religion and that naturally increased my curiosity about science and technology, and I fundamentally believe the two are conflicting.

Everybody else is afraid to fail. I do not really care because when I fail, I try something new.

Startups allow technologists and scientists to take risks and change plans in a way that would be frowned upon in a big company. Having said that, big companies will play a key role in certain areas and in partnerships with little companies. Each has its strengths.

The only way you multiply resources is with technology. To really affect poverty, energy, health, education, or anything else - there is no other way.

As for companies invested in the space - I think its important to distinguish between a good investment and a material climate change technology - you can have the first without the second, even in the "clean tech" space.

We don't need a fuel that's cleaner, we need a fuel that happens to be cleaner, but is half the price of oil.

In my view, it’s irreverence, foolish confidence and naivety combined with persistence, open mindedness and a continual ability to learn that created Facebook, Google, Yahoo, eBay, Microsoft, Apple, Juniper, AOL, Sun Microsystems and others.
