Crime itself can increase inequality. A doubling in crime increases the Gini coefficient by 3% to 4%. When crime increases twofold the share of the rich tercile drops by 1.3%, and the share of the population in the poorest tercile increases.

At some point, if this kind of technological progress continues, it would seem that our descendants will become entirely digital: uploads or artificial intellects implemented on computers. At that point, it is possible that evolutionary selection will again become an important driver of change—but not necessarily of change for the better.

Mixed martial arts aren't like boxing. In boxing, if you lose on your way up? It's pretty much career over. In mixed martial arts, there are so many ways to win and lose... When that happens, you say, 'OK, what did I do wrong?' – you have to be honest with yourself.

Screens are weapons of mass distraction, and as audiences we have to listen and give speakers a chance.

Water is the essence of life. On Earth it's used to grow plants and within industrial processes but in space it takes on a whole new form. We can use water as a radiation shield. One cubic metre of water gives the same protection as Earth's atmosphere and magnetosphere. Water is a molecule made of hydrogen and oxygen- and that happens to be rocket fuel.

In a world where we have 168 million full-time child labourers, we have just over 200 million adults who are jobless. Studies have shown empirically that there is a parallel between child labour and adult unemployment.

The journey we're on doesn't necessarily have a fixed destination; rather, it's about moving in the right direction. The purpose of life is to decipher your own purpose in life. This isn't a contradictory statement; rather, it's a necessary paradox. We exist in order to uncover the reasons for our existence.

Every child should free to be a child. Every child should be free to cry and laugh. Every child should be free to learn and grow. Every child should be free to play and enjoy his or her childhood. Freedom is the key to childhood, and we must protect that.

The world is changing now faster than you and I change our socks! It's constantly changing, and that constantly changing world is going to induce more movie-making. If you go on YouTube, you can see the most talented young people all over the world who take a camera and start to film ideas they have and put them online.

Fear isn't just a neurophysiological phenomenon; it's also socio-cultural. We're enculturated to fear; it's something that we inherit, acquire, and learn – which implies that there is possibility of 'unlearning' our fear.

When individual countries hit a crisis, they've got 2 options, they can either look after themselves (at the cost of their neighbours) or they can create rules which they (and everyone else) will abide by, which requires institutions.

Entrepreneurship is the relentless drive to carry-on, no matter what. Entrepreneurship is tolerance, focus and dedication. Entrepreneurship is this 'true north' belief that whatever this 'thing' is that you want to bring to culture, that you will see it through… and that you are the one here to usher it into existence.
