唯一比外星人更让我害怕的是没有外星人。我们不能是创造物中最好的。我祈祷我们不是全部。如果是这样，我们就麻烦大了。
The only thing that scares me more than space aliens is the idea that there aren't any space aliens. We can't be the best that creation has to offer. I pray we're not all there is. If so, we're in big trouble.
The real competition is not between companies, but between technologies and visions.
The most important thing in science is not so much to obtain new facts as to discover new ways of thinking about them.
In despair, we can find true hope.
