I think the fact that Aldous Huxley wrote Brave New World and talked about anthrax bombs probably helped because at least we... people had the understanding before the war began that's something we didn't want to get into.

And somehow mother nature manages to create this incredible biosphere, to create this incredibly rich environment of animals and plants with this amazingly small amount of data.

The thing that makes me most optimistic is China and India - both of them doing well.

Almost everything about the universe is astounding. I think the most amazing thing is how gifted we are - we are only monkeys who came down from the trees just recently. We have these amazing gifts of music and mathematics and painting and Olympic running.

The world is just - it's wonderful when you look at all the detail. It's just amazing. Nothing is boring if you look at it carefully.

I think that the artificial-intelligence people are making a lot of noise recently, claiming that artificial intelligence is making huge progress and we're going to be outstripped by the machines. But, in my view, this whole field is based on a misconception. I think the brain is analog, whereas the machines are digital. They really are different. So I think that what the machines can do, of course, is wonderful, but it's not the same as what the brain can do.

I am saying that all predictions concerning climate are highly uncertain.
