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.

Information defines your personality, your memories, your skills.

By 2009, computers will disappear. Displays will be written directly onto our retinas by devices in our eyeglasses and contact lenses.

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.

Death gives meaning to our lives. It gives importance and value to time. Time would become meaningless if there were too much of it.

Biology is a software process. Our bodies are made up of trillions of cells, each governed by this process. You and I are walking around with outdated software running in our bodies, which evolved in a very different era.

Inventing is a lot like surfing: you have to anticipate and catch the wave at just the right moment.
