21 Lessons for the 21st Century(84)



Such profound change may well transform the basic structure of life, making discontinuity its most salient feature. From time immemorial life was divided into two complementary parts: a period of learning followed by a period of working. In the first part of life you accumulated information, developed skills, constructed a world view, and built a stable identity. Even if at fifteen you spent most of your day working in the family’s rice field (rather than in a formal school), the most important thing you were doing was learning: how to cultivate rice, how to conduct negotiations with the greedy rice merchants from the big city, and how to resolve conflicts over land and water with the other villagers. In the second part of life you relied on your accumulated skills to navigate the world, earn a living, and contribute to society. Of course even at fifty you continued to learn new things about rice, about merchants, and about conflicts, but these were just small tweaks to well-honed abilities.

By the middle of the twenty-first century, accelerating change plus longer lifespans will make this traditional model obsolete. Life will come apart at the seams, and there will be less and less continuity between different periods of life. ‘Who am I?’ will be a more urgent and complicated question than ever before.4

This is likely to involve immense levels of stress. For change is almost always stressful, and after a certain age most people just don’t like to change. When you are fifteen, your entire life is change. Your body is growing, your mind is developing, your relationships are deepening. Everything is in flux, and everything is new. You are busy inventing yourself. Most teenagers find it frightening, but at the same time, it is also exciting. New vistas are opening before you, and you have an entire world to conquer.

By the time you are fifty, you don’t want change, and most people have given up on conquering the world. Been there, done that, got the T-shirt. You much prefer stability. You have invested so much in your skills, your career, your identity and your world view that you don’t want to start all over again. The harder you’ve worked on building something, the more difficult it is to let go of it and make room for something new. You might still cherish new experiences and minor adjustments, but most people in their fifties aren’t ready to overhaul the deep structures of their identity and personality.

There are neurological reasons for this. Though the adult brain is more flexible and volatile than was once thought, it is still less malleable than the teenage brain. Reconnecting neurons and rewiring synapses is damned hard work.5 But in the twenty-first century, you can hardly afford stability. If you try to hold on to some stable identity, job or world view, you risk being left behind as the world flies by you with a whooooosh. Given that life expectancy is likely to increase, you might subsequently have to spend many decades as a clueless fossil. To stay relevant – not just economically, but above all socially – you will need the ability to constantly learn and to reinvent yourself, certainly at a young age like fifty.

As strangeness becomes the new normal, your past experiences, as well as the past experiences of the whole of humanity, will become less reliable guides. Humans as individuals and humankind as a whole will increasingly have to deal with things nobody ever encountered before, such as super-intelligent machines, engineered bodies, algorithms that can manipulate your emotions with uncanny precision, rapid man-made climate cataclysms, and the need to change your profession every decade. What is the right thing to do when confronting a completely unprecedented situation? How should you act when you are flooded by enormous amounts of information and there is absolutely no way you can absorb and analyse it all? How to live in a world where profound uncertainty is not a bug, but a feature?

To survive and flourish in such a world, you will need a lot of mental flexibility and great reserves of emotional balance. You will have to repeatedly let go of some of what you know best, and feel at home with the unknown. Unfortunately, teaching kids to embrace the unknown and to keep their mental balance is far more difficult than teaching them an equation in physics or the causes of the First World War. You cannot learn resilience by reading a book or listening to a lecture. The teachers themselves usually lack the mental flexibility that the twenty-first century demands, for they themselves are the product of the old educational system.

The Industrial Revolution has bequeathed us the production-line theory of education. In the middle of town there is a large concrete building divided into many identical rooms, each room equipped with rows of desks and chairs. At the sound of a bell, you go to one of these rooms together with thirty other kids who were all born the same year as you. Every hour some grown-up walks in, and starts talking. They are all paid to do so by the government. One of them tells you about the shape of the earth, another tells you about the human past, and a third tells you about the human body. It is easy to laugh at this model, and almost everybody agrees that no matter its past achievements, it is now bankrupt. But so far we haven’t created a viable alternative. Certainly not a scaleable alternative that can be implemented in rural Mexico rather than just in upmarket California suburbs.

So the best advice I could give a fifteen-year-old stuck in an outdated school somewhere in Mexico, India or Alabama is: don’t rely on the adults too much. Most of them mean well, but they just don’t understand the world. In the past, it was a relatively safe bet to follow the adults, because they knew the world quite well, and the world changed slowly. But the twenty-first century is going to be different. Due to the growing pace of change you can never be certain whether what the adults are telling you is timeless wisdom or outdated bias.
