What I have learned from life is to make the most of what you have got.

With genetic engineering, we will be able to increase the complexity of our DNA, and improve the human race. But it will be a slow process, because one will have to wait about 18 years to see the effect of changes to the genetic code. By contrast, computers double their speed and memories every 18 months. There is a real danger that computers will develop intelligence and take over. We urgently need to develop direct connections to the brain so that computers can add to human intelligence rather than be in opposition.

We think we have solved the mystery of creation. Maybe we should patent the universe and charge everyone royalties for their existence.

When something is made idiot proof, they will just make better idiots.

Why are we here? Where do we come from? Traditionally, these are questions for philosophy, but philosophy is dead.

Why do we remember the past, but not the future?

It is said that there's no such thing as a free lunch. But the universe is the ultimate free lunch.
