People talk philosophically, Oh, I don't want to live past 100.' You know, I'd like to hear them say that when they're 99.

When I was a student at MIT, we all shared one computer and it took up a whole building. The computer in your cell phone today is a million times cheaper and a thousand times more powerful. What now fits in your pocket 25 years from now will fit into a blood cell and will again be millions of times more cost effective.

By the end of this decade, computers will disappear as distinct physical objects, with displays built in our eyeglasses, and electronics woven in our clothing, providing full-immersion visual virtual reality.

So what used to fit in a building now fits in your pocket, what fits in your pocket now will fit inside a blood cell in 25 years.

It is doubling now every two years. Doubling every two years means multiplying by 1,000 in 20 years. At that rate we'll meet 100 percent of our energy needs in 20 years.

Death is a great tragedy…a profound loss…I don’t accept it…I think people are kidding themselves when they say they are comfortable with death.

Mobile phones are misnamed. They should be called gateways to human knowledge.
