What the Year 2050 Has in Store for Humankind

Part one: Change is the only constant

Humankind is facing unprecedented revolutions, all our old stories are crumbling and no new story has so far emerged to replace them. How can we prepare ourselves and our children for a world of such unprecedented transformations and radical uncertainties? A baby born today will be thirty-something in 2050. If all goes well, that baby will still be around in 2100, and might even be an active citizen of the 22nd century. What should we teach that baby that will help him or her survive and flourish in the world of 2050 or of the 22nd century? What kind of skills will he or she need in order to get a job, understand what is happening around them and navigate the maze of life?

Unfortunately, since nobody knows how the world will look in 2050 – not to mention 2100 – we don’t know the answer to these questions. Of course, humans have never been able to predict the future with accuracy. But today it is more difficult than ever before, because once technology enables us to engineer bodies, brains and minds, we can no longer be certain about anything – including things that previously seemed fixed and eternal.

A thousand years ago, in 1018, there were many things people didn’t know about the future, but they were nevertheless convinced that the basic features of human society were not going to change. If you lived in China in 1018, you knew that by 1050 the Song Empire might collapse, the Khitans might invade from the north, and plagues might kill millions. However, it was clear to you that even in 1050 most people would still work as farmers and weavers, rulers would still rely on humans to staff their armies and bureaucracies, men would still dominate women, life expectancy would still be about 40, and the human body would be exactly the same. Hence in 1018, poor Chinese parents taught their children how to plant rice or weave silk, and wealthier parents taught their boys how to read the Confucian classics, write calligraphy or fight on horseback – and taught their girls to be modest and obedient housewives. It was obvious these skills would still be needed in 1050.

In contrast, today we have no idea how China or the rest of the world will look in 2050. We don’t know what people will do for a living, we don’t know how armies or bureaucracies will function, and we don’t know what gender relations will be like. Some people will probably live much longer than today, and the human body itself might undergo an unprecedented revolution thanks to bioengineering and direct brain-computer interfaces. Much of what kids learn today will likely be irrelevant by 2050.

At present, too many schools focus on cramming information. In the past this made sense, because information was scarce, and even the slow trickle of existing information was repeatedly blocked by censorship. If you lived, say, in a small provincial town in Mexico in 1800, it was difficult for you to know much about the wider world. There was no radio, television, daily newspapers or public libraries. Even if you were literate and had access to a private library, there was not much to read other than novels and religious tracts. The Spanish Empire heavily censored all texts printed locally, and allowed only a dribble of vetted publications to be imported from outside. Much the same was true if you lived in some provincial town in Russia, India, Turkey or China. When modern schools came along, teaching every child to read and write and imparting the basic facts of geography, history and biology, they represented an immense improvement.

In contrast, in the 21st century we are flooded by enormous amounts of information, and even the censors don’t try to block it. Instead, they are busy spreading misinformation or distracting us with irrelevancies. If you live in some provincial Mexican town and you have a smartphone, you can spend many lifetimes just reading Wikipedia, watching TED talks, and taking free online courses. No government can hope to conceal all the information it doesn’t like. On the other hand, it is alarmingly easy to inundate the public with conflicting reports and red herrings. People all over the world are but a click away from the latest accounts of the bombardment of Aleppo or of melting ice caps in the Arctic, but there are so many contradictory accounts that it is hard to know what to believe. Besides, countless other things are just a click away, making it difficult to focus, and when politics or science look too complicated it is tempting to switch to funny cat videos, celebrity gossip or porn.

In such a world, the last thing a teacher needs to give her pupils is more information. They already have far too much of it. Instead, people need the ability to make sense of information, to tell the difference between what is important and what is unimportant, and above all to combine many bits of information into a broad picture of the world.

In truth, this has been the ideal of western liberal education for centuries, but up till now even many western schools have been rather slack in fulfilling it. Teachers allowed themselves to focus on shoving data while encouraging pupils “to think for themselves”. Due to their fear of authoritarianism, liberal schools had a particular horror of grand narratives. They assumed that as long as we give students lots of data and a modicum of freedom, the students will create their own picture of the world, and even if this generation fails to synthesise all the data into a coherent and meaningful story of the world, there will be plenty of time to construct a good synthesis in the future. We have now run out of time. The decisions we will take in the next few decades will shape the future of life itself, and we can take these decisions based only on our present world view. If this generation lacks a comprehensive view of the cosmos, the future of life will be decided at random.

Part two: The heat is on

Besides information, most schools also focus too much on providing pupils with a set of predetermined skills such as solving differential equations, writing computer code in C++, identifying chemicals in a test tube or conversing in Chinese. Yet since we have no idea how the world and the job market will look in 2050, we don’t really know what particular skills people will need. We might invest a lot of effort teaching kids how to write in C++ or how to speak Chinese, only to discover that by 2050 AI can code software far better than humans, and a new Google Translate app enables you to conduct a conversation in almost flawless Mandarin, Cantonese or Hakka, even though you only know how to say “Ni hao”.

So what should we be teaching? Many pedagogical experts argue that schools should switch to teaching “the four Cs” – critical thinking, communication, collaboration and creativity. More broadly, schools should downplay technical skills and emphasise general-purpose life skills. Most important of all will be the ability to deal with change, to learn new things and to preserve your mental balance in unfamiliar situations. In order to keep up with the world of 2050, you will need not merely to invent new ideas and products – you will above all need to reinvent yourself again and again.

For as the pace of change increases, not just the economy, but the very meaning of “being human” is likely to mutate. In 1848, the Communist Manifesto declared that “all that is solid melts into air”. Marx and Engels, however, were thinking mainly about social and economic structures. By 2048, physical and cognitive structures will also melt into air, or into a cloud of data bits.

In 1848, millions of people were losing their jobs on village farms, and were going to the big cities to work in factories. But upon reaching the big city, they were unlikely to change their gender or to add a sixth sense. And if they found a job in some textile factory, they could expect to remain in that profession for the rest of their working lives.

By 2048, people might have to cope with migrations to cyberspace, with fluid gender identities, and with new sensory experiences generated by computer implants. If they find both work and meaning in designing up-to-the-minute fashions for a 3D virtual-reality game, within a decade not just this particular profession, but all jobs demanding this level of artistic creation might be taken over by AI. So at 25, you introduce yourself on a dating site as “a twenty-five-year-old heterosexual woman who lives in London and works in a fashion shop.” At 35, you say you are “a gender-non-specific person undergoing age- adjustment, whose neocortical activity takes place mainly in the NewCosmos virtual world, and whose life mission is to go where no fashion designer has gone before”. At 45, both dating and self-definitions are so passé. You just wait for an algorithm to find (or create) the perfect match for you. As for drawing meaning from the art of fashion design, you are so irrevocably outclassed by the algorithms, that looking at your crowning achievements from the previous decade fills you with embarrassment rather than pride. And at 45, you still have many decades of radical change ahead of you.

Please don’t take this scenario literally. Nobody can really predict the specific changes we will witness. Any particular scenario is likely to be far from the truth. If somebody describes to you the world of the mid-21st century and it sounds like science fiction, it is probably false. But then if somebody describes to you the world of the mid 21st-century and it doesn’t sound like science fiction – it is certainly false. We cannot be sure of the specifics, but change itself is the only certainty.

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 15 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 50 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 21st 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.
