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.

No one undertakes research in physics with the intention of winning a prize. It is the joy of discovering something no one knew before.

Science can explain the universe without the need for a Creator.

It [AI] would take off on its own and redesign itself at an ever increasing rate. Humans, who are limited by slow biological evolution, couldn't compete and would be superseded.

TEAMWORK...means never having to take all the blame yourself.

There are no black holes - in the sense of regimes from which light can't escape to infinity. There are however apparent horizons which persist for a period of time.

Just like a computer, we must remember things in the order in which entropy increases. This makes the second law of thermodynamics almost trivial. Disorder increases with time because we measure time in the direction in which disorder increases. You can't have a safer bet than that!
