The media always tries to make everything into a disaster, but it's mostly rubbish.

The key to having an interesting life is to always say "yes" to anything crazy.

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.

Humanity looks to me like a magnificent beginning but not the final word.

All the time worrying about pushing the children and getting them to be mathematically literate and all that stuff. It's terribly hard on the kids. It's also hard on the teachers. And I think it's totally useless.

If you're in the business world, that's what's expected: You should go bust and then start again on something else. So it's a much more relaxed kind of a culture. It's also competitive, but not in such a vicious way. I think the academic world is actually much more destructive of young people.

For any speculation which does not at first glance look crazy, there is no hope.
