Once released, former hostages encounter a myriad of practical issues—closed bank accounts, lapsed insurance, and the need for specialised medical and dental care that isn't readily available. They might also require physical therapy among other medical treatments. It's not just the hostage who suffers, but their entire family. In some cases, families endure greater agony, living in uncertainty about their loved one's fate.

Our senses allow us to perceive, but they're incredibly limited. Science sees far beyond our human blind spots, and the reaches of this 'bubble' our senses create for us. When you're in a bubble, you inhabit a form of fictional reality, and we've seen the dangerous consequences of this in financial bubbles, stock market bubbles, real estate bubbles.

With technology, we're creating a lot more hammers – and with more hammers, we're able to find more nails. The question is whether those hammers are being made for the right purposes, and whether they will serve the right purpose.

Much of our future work may end up being about convincing them that we are conscious, and worth keeping around.

We have a much more connected marketplace. We have had, what I reckon to be an extremely overvalued stock market since 2000. When you have that situation, you are prone to very sudden negative revaluations.

So, the lesson I eventually learned was to distinguish between which teams are sincere in promoting true teamwork, and which are jingoistic self-serving pretenders. Teamwork does make the dream work, but not every team is worthy.

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!

What I like the most and essentially is never done is to start off a negotiation by talking about how you'll negotiate, what's the process going to be? And to say things like 'my goal in this negotiation is to reach an agreement with you in which we create a giant pie and split it evenly and can we agree that that's our goal?'

Increasingly heavy-handed purges of crime will simply move perpetrators into different industries, increase the severity of crime, or create extremist groups. There is very little more dangerous in the world than individuals with nothing to lose.

In order to build a truly powerful brand, you can't just sell a product. You need a brand that is authentic and resonates deeply with your fans. The reason we've been able to amass so many followers around the world in such a short period of time is that they aren't just consuming a product; they're finding meaning in it.

Consciousness is any kind of subjective experience whatsoever. The philosopher, Thomas Nagel, put it like this, 'for a conscious organism, there is something it is like to be that organism…' – there is something it is like to be me, to be you, to be a dolphin – but there's probably nothing like what it is to be a chair, table, or iPhone.

Music is something that affects your senses in a way that nothing else really can- it's like a time-travel portal! You can listen to something and it transports back to that place… that bar… that nightclub… that time with your friends….
