I'm convinced that before the year 2000 is over, the first child will have been born on the moon.

For my confirmation, I didn't get a watch and my first pair of long pants, like most Lutheran boys. I got a telescope. My mother thought it would make the best gift.

Our sun is one of 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living things in that enormous immensity.

[Stated in 1965:] Machines will be capable, within 20 years, of doing any work a man can do.

My prediction? 3-0.

I was not predicting the future, I was trying to prevent it.
