My greatest fear is that we have learnt nothing. Individually, we have learnt that the longer your population lives healthy, the better off your economy will be.

Democracies are not very good at long term planning in general and population ageing is the utmost long term planning.

We are all headed towards aging populations because we are living longer and measuring GDP growth is not the way to decide whether a society or an economy are flourishing. Population aging is evidence that we've been doing a lot of things right.

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.

The future is baked into the population of today, and that makes it very convenient for looking at the next couple of decades as our future soldiers are today in nursery school, and our future retirees are entering college.

Think about your water kettle. When you heat the water and you see the transition from water to gas, not all water molecules are converted at once. The same happened in the world economy. Since this transition was associated with such a fantastic increase in income per capita, those societies that took off first increased their gap from the rest of the world tremendously.

There is a certain conventional wisdom about the way that humanity evolved over time. The puzzling element is that much of the gain that we made in the technological realm were converted into more people, rather than into richer people up until very, very recently. World income per capita has increased 14-fold in the past 200 years, whereas over 300,000 years of human existence, it hardly changed.

Consider for a moment residents of the city of Jerusalem in the Roman period and whisk these individuals in a time machine nearly 2000 years forward to Ottoman Jerusalem. Those individuals from the Roman period will be able to adapt nearly instantaneously. But if you whisk these individuals an additional 200 hundred years forward to present day Jerusalem, these individuals would be entirely shocked. Past knowledge will be largely obsolete. New technologies would appear as witchcraft.

The politics of identity has gone very wrong in many cases. Politicians often forget that people are much more complex, and are a mix of many identities – and each of these identities can be of differing importance to the individual. A Muslim man from Somalia, who is a chess player, may have his chess-playing as his main source of identity, for example.

If those assets are not being productively converted into goods and services that make the world a better place, it's a missed opportunity. Over the past half-century, we've standardised on a 'way' to do things – and that's clearly flawed but continues. We need managers and leaders to up their game if we're going to hope to tackle the environmental, inequality and other crises we face.

It's fair to say that life felt more secure 40 years ago. You felt safer in your home, on the streets, in school, you just felt safer. If people suggest that humanity is becoming less 'human' – it's because we've allowed civilized conduct to deteriorate and that's what I've fought against for my entire professional career.

I've said to my children, and grandchildren, that if you do the right thing – there's no guarantee that the right thing will happen. That's the way of the world. If you do the wrong thing however, you'll face karma. If you do the wrong thing? At some point in your life, something bad is going to happen to you.

Society must demand that you comport yourself within a framework of rules. Once those rules break, society breaks down.

We need to be saying, '…fuck you! Stop pouring itching powder over me!' It's like someone is pouring itching powder over us, all day, every day. The same person pouring itching powder over us is also the person saying, 'mate… try this meditation app….'

I don't think it's a coincidence that globally, we're having the biggest crisis of democracy since the 1930s. At the same time as we're finding it hard to focus and pay attention, we also can't listen to each other and sustain our attention on collective problems.

What we think of as important today is rarely what really matters. In 10 years' time, you're not going to regret using the wrong Instagram filter, or not getting enough likes on a social media post. You will however, regret not reaching out to someone before it was too late.
