The only regrets I have are rather prosaic - like I wish I went for a swim in the Pacific.

When it comes to helping out, I don't believe in doing it for the media attention. My goal is to support the organizations that need help.

I'm a very private person that prefers a low profile.

Even before I helped to co-found Microsoft, I saw a connected future . . . I called that future The Wired World.

I think it's going to be great if people can buy a ticket to fly up and see black sky and the stars. I'd like to do it myself-but probably after it has flown a serious number of times first!

What should exist? To me, that's the most exciting question imaginable. What do we need that we don't have? How can we realize our potential?

That would be such a life-changing thing, for us all to know that there are other beings out there who we could potentially communicate with, or maybe we are listening to a signal that they transmitted hundreds of millennia ago.
