Religion asks you to believe things without questioning, and technology and science always encourage you to ask hard questions and why it is important in science and technology. So I was always interested in science and technology.

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.

I don't believe - till something radical changes that we are not on track to do - that hybrids are material to climate change. They're fashionable, everybody loves them, the Prius is selling well, but so are Gucci bags. But they don't impact the way the world carries stuff. You know it's a fashion statement.

Spreadsheets are fiction. Believing in what you're doing and what you're building is what's important.
