We are on dangerous terrain when government picks winners and losers in the economy by subsidizing favored products and industries.

I don't like the idea of capitalism anyway. Because it's not capital we are talking about; it's knowledge and creating well-being. Because I mean, that gets people on the wrong track when it's capital and how we allocate capital - no. How do we create the Republic of Science in America? How do we have a system of mutual benefits where people succeed by helping others improve their lives? So I don't like that at all.

Everything I give, pretty much, is public. Not every donor wants to - or is willing to get the kind of abuse and attacks that we do, or death threats, so they're not willing to have their names out. I think the other side is pushing for that because they want to intimidate people so they won't oppose it.

The only way you improve is to try new things.

Being captive to quarterly earnings isn't consistent with long-term value creation. This pressure and the short term focus of equity markets make it difficult for a public company to invest for long-term success, and tend to force company leaders to sacrifice long-term results to protect current earnings.

I don't believe in a plumb line. I believe in the exchange of ideas.

I think this is so important - what's not done well at education at every level - is helping kids find, as I discovered for myself, what I was good at. I was very lucky to find out that at an early age, which set my direction in life.
