With participatory culture, economics dictates that we pour more resources into building an infrastructure platform that anyone can use, so most resources go into empowering 'the long tail'. Small groups of people can come together and make use of a powerful infrastructure to enable them to pursue their own passions and interests, without regard for popularity.

We have reason to be optimistic, but until the public get angry enough about homelessness with politicians rather than the homeless, nothing will change. Politicians respond to public opinions that they believe are electorally significant.

Contemporary photography is quite exploitative – and looks at people as objects in a display-case rather than as individuals with whom we have a shared common humanity, connection, and solidarity. Photography has gone from I am part of this, to look at this.

Unless you learn and grow continuously, you're probably going to end up as one of the 90% who don't make it.

The essence of the evolving global economic system is that all countries are dependent on one another in some way, and this includes finance. Emerging and developing countries are dependent on capital inflows from developed regions. But developed regions are also dependent on funds from the developing world!

It has become appallingly obvious that our technology has exceeded our humanity.

The most successful teams are the ones who present with authenticity and passion. You could have the next cancer cure, but unless your audience believes in you, they won't invest in you.

The theory describes only the way objects interact with one another, without indicating what happens between one interaction and the next one.

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.

To be a billionaire in America today is less a matter of merit than it is a matter of being at the right place at the right time, and being a beneficiary of a set of rules designed to benefit billionaires.

If your judgement is hijacked by emotions such as rage, fear, neediness, loneliness, or anger, you will act out of impulse – not out of value. This can be incredibly harmful – when the dust settles, you may realise you've messed-up.

We need to challenge the notion that if you don't feel like a superhero, then you must not be the right person for the job. Today's most important challenges are met by teams of people, as opposed to a single superhero.
