The only real competitive advantage that's durable is cost and innovation – as long as innovation happens along the trajectory that takes into account stakeholders, not just shareholders. Your customers, employees, shareholders, and communities in which you operate are all stakeholders. If you innovate, you need to think about all these groups – and then, guess what, the shareholders will benefit.

This problem originated in the most sophisticated and advanced financial markets because those are the markets where leverage was the greatest and people took the most advantage of it.

Response to, and resolution of what lay behind the merciless attack, should theoretically still be for peaceful resolution in accordance with the UN Charter.

Human cooperation is the greatest force in history- it enabled us to put people on the moon, build microprocessors and advance medicine. Human cooperation with intelligent machines will define the next era of history.

It is essential to think about it systematically and to include demographics as it's the study of people – who we are, where we are- people are the foundation of every society. There is a lot of misunderstanding about demography and one of the biggest misunderstandings is that it's destiny. If it's, destiny, it is not that interesting to study, but it's not destiny.

Population aging is evidence that we've been doing a lot of things right. We're confident that if we have children, they will live long lives as well and we've never had those trends before in all human history.

Online trolling and abuse is a real problem now. A lot of people who want to express an opinion now are fearful that they'll get piled-on. And there's no real immunity from it: Zadie Smith's brilliant New Yorker story 'Now More Than Ever' is really an expression of her terror of the arbitrary possibility of being judged by a moralistic internet pile-on, of being as they say cancelled.

The physical world isn't going away. We are a physical species. While digitisation is enabling incredible things – the best companies seem to be combining the physical and digital; they seem to understand what it means when products and services are connected.

Adversity is happening all around us at the individual level, it's happening at a company level, it's happening at industry levels; and we can either face it and learn from it or we can pretend it's not happening. And I think that is the key.

I believe it's crucial, especially in social settings, to be both interesting and interested. Being well-informed and keeping up with current events make you more engaging, but showing genuine interest in others is key.

Only a handful of diplomats and governments are prepared to put the global good before the national interest. Seldom is it the case for any diplomat that they put the global good high up on the agenda; in my career I've seen it very rarely.
