The real question is not are there other forms of life in the universe, but are there other intelligent forms of life out there right now. Because the universe is not only really big but it's also really long. It's been around for a long time; it's going to be around for a long time.

Authoritarian governments are now trying to ensure that the increasingly free flow of ideas and information through cyberspace fuels their economies without threatening their political power.

NASA is increasingly not the future of space exploration. I love the fact that we have private sector folks devoting a lot of money to stimulate innovation in space technology.

The developed world should neither shelter nor militarily destabilize authoritarian regimes unless those regimes represent an imminent threat to the national security of other states. Developed states should instead work to create the conditions most favorable for a closed regime's safe passage through the least stable segment of the J curve however and whenever the slide toward instability comes. And developed states should minimize the risk these states pose the rest of the world as their transition toward modernity begins.

Whether it is gun control lobby, health care lobby, or abortion, pro-choice lobby, whatever it is, people are always trying to say that it is about restricting rights and they are never really prepared to talk about what the honest tradeoffs are. One of the things we need to do a better job of is actually painting those tradeoffs.

We live in a fantastically wealthy country. We don't have to worry about food. We don't have to worry about clothing. We don't have to worry about our safety. It's very easy for me to be an environmentalist. It's very easy for me to care about making sure that we protect the forests and the whales, and all that stuff.

I would rather people not smoke. I certainly appreciate the fact that smoking is not legal in restaurants and bars. That used to stop me from going out at night because you'd go someplace and your clothes would reek and you wouldn't enjoy the experience and that affects your rights. It's always a question.
