The purpose of thinking about the future is not to predict it but to raise people's hopes.

The technologies that raise the fewest ethical problems are those that work on a human scale, brightening the lives of individual people.

I see a bright future for the biotechnology industry when it follows the path of the computer industry, the path that von Neumann failed to foresee, becoming small and domesticated rather than big and centralized.

You ask: what is the meaning or purpose of life? I can only answer with another question: do you think we are wise enough to read God's mind?

Younger people have so many opportunities. I don't see any pessimism among them.

I have the freedom to do what I want... bright people to talk to every day.
