Twitter as a service is very oriented towards people providing short, succinct and relatively immediate 'in the moment' updates on what they're interested in and how they feel- and at a very large scale. At the moment we have around 250 million twitter users! We felt it was the ideal environment for us to test our hypotheses that we could, in fact, gauge the public's mood state from this type of data- and use that to study and even predict socioeconomic phenomenon of which the market is just one.

The only way to innovate is to follow Aristotle's prescription. To create a future that is different to the past is to imagine possibilities and choose the one for which the most compelling argument can be made, not the one for which there is the most data. If companies want to innovate, they need to realise that data analytics is killing innovation yet is lauded and used increasingly.

What makes Guantánamo so horrible is the fact that the majority of these men are innocent and have no hope of release in the future. Our government has made no concrete steps to releasing these men.

In the multi-agent model, if you feed in the real price of the market, they show that before the large dives in market prices you could see the crowding that was beginning to happen behind the scenes, even though you couldn't see it in the price.

Every acorn is already programmed to become an oak tree, every embryo is programmed to become a baby, and every bud is programmed to become a blossom. Human beings are programmed as well, but we have something an acorn does not; free will. Every moment we live- we either allow the natural intelligence of life to unfold through us- or not. That natural intelligence is love.

Arguably, the biggest challenge we face right now as humans and as a society is climate change and the issues associated with our negative impact on the environment. So, this has become a key element of my business endeavours along with all surrounding technologies that help tackle this issue.

If you have a bottle of water in your house, it belongs to you. Nobody can touch it without your permission, nobody can get into your house without your permission. This doesn't apply to the internet world. Facebook can access your room and your house without your consent. They can tear down your house, they can delete and block your digital life.

We weren't involved in politics and had nothing to do with the government. But they took everything we had, our seven companies and the company plane. And it's a miracle they didn't kill us.

You absolutely need some funding to get started. But ideally, that should come from remortgaging your house or borrowing a bit from friends, family, or parents—just enough to have a small amount of money, but not too much. That way, you can copy, pivot, test, learn, and prove out your model on a small scale.

Science without religion is lame, religion without science is blind.

Transparency is paramount. We have to make sure that we have sufficient transparency in the investments we are making, to be able to manage risk for our clients.

I think there's a big misconception—sometimes called 'toxic positivity' or 'good vibes only'—that a happy life is one where we only experience positive emotions. But that's just patently false. Evolutionarily speaking, our negative emotions serve a really important purpose: they cue us to take action.
