[T]he yeoman's work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest.

Computer chips will cost about a penny. That's the cost of scrap paper. The Internet will be basically for free and it will be inside our contact lens. When we blink, we will go online. When we see somebody that we don't recognize, our contact lens will identify who they are, print out their biography in your contact lens and translate, if they're speaking Chinese, into English with subtitles as they speak.

I'm a physicist, and we have something called Moore's Law, which says computer power doubles every 18 months. So every Christmas, we more or less assume that our toys and appliances are more or less twice as powerful as the previous Christmas.

In the future we'll be able to mentally contact anybody we want, see whatever image we want. And when we don't like it, we'll just turn it off.

Chances are, when we meet intelligent life forms in outer space they're going to be descended from predators.
