[the impact of the internet on liberty and free speech has been] very positive indeed – not so much two steps forward and one step back, as ten steps forward for every step back. By breaking the oligopoly of the established press and letting everyone be a publisher, it has made information much harder for the powerful to control.

If you had to make everything up in your life, from the start, with no input whatsoever – that wouldn't be freedom – you'd be less free; you'd have to think constantly about what you should or should not do. There would be no structure for your life choices.

We have to leave behind the myth that our economies are actually fit for the present that we understand, and the vision of the future we want to create. We need to redesign economics for our times.

Politically and practically, the Euro Zone nations cannot be seen to bail-out Greece. Not only would this set a potentially dangerous precedent, but it could also affect the overall financial stability of the system itself.

The real tragedy is that we have become so accustomed to injustice that we no longer recognize it when we see it. We've normalized inequality, normalized discrimination, normalized the idea that some people matter less than others.

The consumer is far better educated today than he ever was. Consumers don't need to rely on intermediaries to tell them what is good or bad- people are social, they share information with friends and strangers, and go to a broader community for help and assistance.

I completely appreciate that people think social media is a waste of my time, but spending all day being obsessed with our customer, interacting with them in every way that I can, answering every question, trying to understand everything that I can about them, matches everything that we do and everything that we produce.

I still believe that nuclear is the greatest risk we face as a society today.

This decade, their GDP will increase by about $12 trillion, i.e. they will create another one of themselves! More importantly, the share of consumption in this decade's growth will be bigger and this is where the big opportunity lies.

We are living in a world where the top 1% of the world's population own more of our planet's wealth than the bottom 95% combined. We live in a world where billions exist in abject poverty without access to the basic food, water, shelter which the rest of us take for granted.

Without understanding the rules of the game, you might assume that your outcomes are determined mostly by luck. People who end up unhappy about what they get conclude that they were unlucky or that the system was rigged against them. After enough of these experiences, they believe that's just how the world works.

Music is woven into the fabric of the universe. As far back as Pythagoras and Kepler, scientists were writing about the fact that music was intrinsic in the planets… part of the harmonic series in sound. We also have a whole branch of knowledge called zoomusicology, which shows that an appreciation of music and sound is a part of nature, not just unique to humans.
