21 Lessons for the 21st Century Read online

  Humans vote with their feet. In my travels around the world I have met numerous people in many countries who wish to emigrate to the USA, to Germany, to Canada or to Australia. I have met a few who want to move to China or Japan. But I am yet to meet a single person who dreams of emigrating to Russia.

  As for ‘global Islam’, it attracts mainly those who were born in its lap. While it may appeal to some people in Syria and Iraq, and even to alienated Muslim youths in Germany and Britain, it is hard to see Greece or South Africa – not to mention Canada or South Korea – joining a global caliphate as the remedy to their problems. In this case, too, people vote with their feet. For every Muslim youth from Germany who travelled to the Middle East to live under a Muslim theocracy, probably a hundred Middle Eastern youths would have liked to make the opposite journey, and start a new life for themselves in liberal Germany.

  This might imply that the present crisis of faith is less severe than its predecessors. Any liberal who is driven to despair by the events of the last few years should just recollect how much worse things looked in 1918, 1938 or 1968. At the end of the day, humankind won’t abandon the liberal story, because it doesn’t have any alternative. People may give the system an angry kick in the stomach but, having nowhere else to go, they will eventually come back.

  Alternatively, people may completely give up on having a global story of any kind, and instead seek shelter with local nationalist and religious tales. In the twentieth century, nationalist movements were an extremely important political player, but they lacked a coherent vision for the future of the world other than supporting the division of the globe into independent nation states. Thus Indonesian nationalists fought against Dutch domination, and Vietnamese nationalists wanted a free Vietnam, but there was no Indonesian or Vietnamese story for humanity as a whole. When it came time to explain how Indonesia, Vietnam and all the other free nations should relate to one another, and how humans should deal with global problems such as the threat of nuclear war, nationalists invariably turned to either liberal or communist ideas.

  But if both liberalism and communism are now discredited, maybe humans should abandon the very idea of a single global story? After all, weren’t all these global stories – even communism – the product of Western imperialism? Why should Vietnamese villagers put their faith in the brainchild of a German from Trier and a Manchester industrialist? Maybe each country should adopt a different idiosyncratic path, defined by its own ancient traditions? Perhaps even Westerners should take a break from trying to run the world, and focus on their own affairs for a change?

  This is arguably what is happening all over the globe, as the vacuum left by the breakdown of liberalism is tentatively filled by nostalgic fantasies about some local golden past. Donald Trump coupled his calls for American isolationism with a promise to ‘Make America Great Again’ – as if the USA of the 1980s or 1950s was a perfect society that Americans should somehow recreate in the twenty-first century. The Brexiteers dream of making Britain an independent power, as if they were still living in the days of Queen Victoria and as if ‘splendid isolation’ were a viable policy for the era of the Internet and global warming. Chinese elites have rediscovered their native imperial and Confucian legacies, as a supplement or even substitute for the doubtful Marxist ideology they imported from the West. In Russia, Putin’s official vision is not to build a corrupt oligarchy, but rather to resurrect the old tsarist empire. A century after the Bolshevik Revolution, Putin promises a return to ancient tsarist glories with an autocratic government buoyed by Russian nationalism and Orthodox piety spreading its might from the Baltic to the Caucasus.

  Similar nostalgic dreams that mix nationalist attachment with religious traditions underpin regimes in India, Poland, Turkey and numerous other countries. Nowhere are these fantasies more extreme than in the Middle East, where Islamists want to copy the system established by the Prophet Muhammad in the city of Medina 1,400 years ago, while fundamentalist Jews in Israel outdo even the Islamists, and dream of going back 2,500 years to biblical times. Members of Israel’s ruling coalition government talk openly about their hope of expanding modern Israel’s borders to match more closely those of biblical Israel, of reinstating biblical law, and even of rebuilding the ancient Temple of Yahweh in Jerusalem in place of the Al-Aqsa mosque.10

  Liberal elites look in horror at these developments, and hope that humanity will return to the liberal path in time to avert disaster. In his final speech to the United Nations in September 2016, President Obama warned his listeners against retreating ‘into a world sharply divided, and ultimately in conflict, along age-old lines of nation and tribe and race and religion’. Instead, he said, ‘the principles of open markets and accountable governance, of democracy and human rights and international law … remain the firmest foundation for human progress in this century’.11

  Obama has rightly pointed out that despite the numerous shortcomings of the liberal package, it has a much better record than any of its alternatives. Most humans never enjoyed greater peace or prosperity than they did under the aegis of the liberal order of the early twenty-first century. For the first time in history, infectious diseases kill fewer people than old age, famine kills fewer people than obesity, and violence kills fewer people than accidents.

  But liberalism has no obvious answers to the biggest problems we face: ecological collapse and technological disruption. Liberalism traditionally relied on economic growth to magically solve difficult social and political conflicts. Liberalism reconciled the proletariat with the bourgeoisie, the faithful with the atheists, the natives with the immigrants, and the Europeans with the Asians by promising everybody a larger slice of the pie. With a constantly growing pie, that was possible. However, economic growth will not save the global ecosystem – just the opposite, it is the cause of the ecological crisis. And economic growth will not solve technological disruption – it is predicated on the invention of more and more disruptive technologies.

  The liberal story and the logic of free-market capitalism encourage people to have grand expectations. During the latter part of the twentieth century, each generation – whether in Houston, Shanghai, Istanbul or São Paulo – enjoyed better education, superior healthcare and larger incomes than the one that came before it. In coming decades, however, owing to a combination of technological disruption and ecological meltdown, the younger generation might be lucky to just stay in place.

  We are consequently left with the task of creating an updated story for the world. Just as the upheavals of the Industrial Revolution gave birth to the novel ideologies of the twentieth century, so the coming revolutions in biotechnology and information technology are likely to require fresh visions. The next decades might therefore be characterised by intense soul-searching and by formulating new social and political models. Could liberalism reinvent itself yet again, just as it did in the wake of the 1930s and 1960s crises, emerging as more attractive than ever before? Could traditional religion and nationalism provide the answers that escape the liberals, and could they use ancient wisdom to fashion an up-to-date world view? Or perhaps the time has come to make a clean break with the past, and craft a completely new story that goes beyond not just the old gods and nations, but even the core modern values of liberty and equality?

  At present, humankind is far from reaching any consensus on these questions. We are still in the nihilist moment of disillusionment and anger, after people have lost faith in the old stories but before they have embraced a new one. So what next? The first step is to tone down the prophecies of doom, and switch from panic mode to bewilderment. Panic is a form of hubris. It comes from the smug feeling that I know exactly where the world is heading – down. Bewilderment is more humble, and therefore more clear-sighted. If you feel like running down the street crying ‘The apocalypse is upon us!’, try telling yourself ‘No, it’s not that. Truth is, I just don’t understand what’s going on in the world.’

  The following chapters will try to clarify some of the bewildering new possibilities we face, and how we might proceed from here. But before exploring potential solutions to humanity’s predicaments we need a better grasp of the challenge technology poses. The revolutions in information technology and biotechnology are still in their infancy, and it is debatable to what extent they are really responsible for the current crisis of liberalism. Most people in Birmingham, Istanbul, St Petersburg and Mumbai are only dimly aware, if at all, of the rise of artificial intelligence and its potential impact on their lives. It is undoubtable, however, that the technological revolutions will gather momentum in the next few decades, and will confront humankind with the hardest trials we have ever encountered. Any story that seeks to gain humanity’s allegiance will be tested above all in its ability to deal with the twin revolutions in infotech and biotech. If liberalism, nationalism, Islam or some novel creed wishes to shape the world of the year 2050, it will need not only to make sense of artificial intelligence, Big Data algorithms and bioengineering – it will also need to incorporate them into a new meaningful narrative.

  To understand the nature of this technological challenge, perhaps it would be best to start with the job market. Since 2015 I have been travelling around the world talking with government officials, business people, social activists and schoolkids about the human predicament. Whenever they become impatient or bored by all the talk of artificial intelligence, Big Data algorithms and bioengineering, I usually need to mention just one magic word to snap them back to attention: jobs. The technological revolution might soon push billions of humans out of the job market, and create a massive new useless class, leading to social and political upheavals that no existing ideology knows how to handle. All the talk about technology and ideology might sound abstract and remote, but the v
ery real prospect of mass unemployment – or personal unemployment – leaves nobody indifferent.

  WORK

  When you grow up, you might not have a job

  We have no idea what the job market will look like in 2050. It is generally agreed that machine learning and robotics will change almost every line of work – from producing yoghurt to teaching yoga. However, there are conflicting views about the nature of the change and its imminence. Some believe that within a mere decade or two, billions of people will become economically redundant. Others maintain that even in the long run automation will keep generating new jobs and greater prosperity for all.

  So are we on a verge of a terrifying upheaval, or are such forecasts yet another example of ill-founded Luddite hysteria? It is hard to say. Fears that automation will create massive unemployment go back to the nineteenth century, and so far they have never materialised. Since the beginning of the Industrial Revolution, for every job lost to a machine at least one new job was created, and the average standard of living has increased dramatically.1 Yet there are good reasons to think that this time it is different, and that machine learning will be a real game changer.

  Humans have two types of abilities – physical and cognitive. In the past, machines competed with humans mainly in raw physical abilities, while humans retained an immense edge over machines in cognition. Hence as manual jobs in agriculture and industry were automated, new service jobs emerged that required the kind of cognitive skills only humans possessed: learning, analysing, communicating and above all understanding human emotions. However, AI is now beginning to outperform humans in more and more of these skills, including in the understanding of human emotions.2 We don’t know of any third field of activity – beyond the physical and the cognitive – where humans will always retain a secure edge.

  It is crucial to realise that the AI revolution is not just about computers getting faster and smarter. It is fuelled by breakthroughs in the life sciences and the social sciences as well. The better we understand the biochemical mechanisms that underpin human emotions, desires and choices, the better computers can become in analysing human behaviour, predicting human decisions, and replacing human drivers, bankers and lawyers.

  In the last few decades research in areas such as neuroscience and behavioural economics allowed scientists to hack humans, and in particular to gain a much better understanding of how humans make decisions. It turned out that our choices of everything from food to mates result not from some mysterious free will, but rather from billions of neurons calculating probabilities within a split second. Vaunted ‘human intuition’ is in reality ‘pattern recognition’.3 Good drivers, bankers and lawyers don’t have magical intuitions about traffic, investment or negotiation – rather, by recognising recurring patterns, they spot and try to avoid careless pedestrians, inept borrowers and dishonest crooks. It also turned out that the biochemical algorithms of the human brain are far from perfect. They rely on heuristics, shortcuts and outdated circuits adapted to the African savannah rather than to the urban jungle. No wonder that even good drivers, bankers and lawyers sometimes make stupid mistakes.

  This means that AI can outperform humans even in tasks that supposedly demand ‘intuition’. If you think AI needs to compete against the human soul in terms of mystical hunches – that sounds impossible. But if AI really needs to compete against neural networks in calculating probabilities and recognising patterns – that sounds far less daunting.

  In particular, AI can be better at jobs that demand intuitions about other people. Many lines of work – such as driving a vehicle in a street full of pedestrians, lending money to strangers, and negotiating a business deal – require the ability to correctly assess the emotions and desires of other people. Is that kid about to jump onto the road? Does the man in the suit intend to take my money and disappear? Will that lawyer act on his threats, or is he just bluffing? As long as it was thought that such emotions and desires were generated by an immaterial spirit, it seemed obvious that computers will never be able to replace human drivers, bankers and lawyers. For how can a computer understand the divinely created human spirit? Yet if these emotions and desires are in fact no more than biochemical algorithms, there is no reason why computers cannot decipher these algorithms – and do so far better than any Homo sapiens.

  A driver predicting the intentions of a pedestrian, a banker assessing the credibility of a potential borrower, and a lawyer gauging the mood at the negotiation table don’t rely on witchcraft. Rather, unbeknownst to them, their brains are recognising biochemical patterns by analysing facial expressions, tones of voice, hand movements, and even body odours. An AI equipped with the right sensors could do all that far more accurately and reliably than a human.

  Hence the threat of job losses does not result merely from the rise of infotech. It results from the confluence of infotech with biotech. The way from the fMRI scanner to the labour market is long and tortuous, but it can still be covered within a few decades. What brain scientists are learning today about the amygdala and the cerebellum might make it possible for computers to outperform human psychiatrists and bodyguards in 2050.

  AI not only stands poised to hack humans and outperform them in what were hitherto uniquely human skills. It also enjoys uniquely non-human abilities, which make the difference between an AI and a human worker one of kind rather than merely of degree. Two particularly important non-human abilities that AI possesses are connectivity and updateability.

  Since humans are individuals, it is difficult to connect them to one another and to make sure that they are all up to date. In contrast, computers aren’t individuals, and it is easy to integrate them into a single flexible network. Hence what we are facing is not the replacement of millions of individual human workers by millions of individual robots and computers. Rather, individual humans are likely to be replaced by an integrated network. When considering automation it is therefore wrong to compare the abilities of a single human driver to that of a single self-driving car, or of a single human doctor to that of a single AI doctor. Rather, we should compare the abilities of a collection of human individuals to the abilities of an integrated network.

  For example, many drivers are unfamiliar with all the changing traffic regulations, and they often violate them. In addition, since every vehicle is an autonomous entity, when two vehicles approach the same junction at the same time, the drivers might miscommunicate their intentions and collide. Self-driving cars, in contrast, can all be connected to one another. When two such vehicles approach the same junction, they are not really two separate entities – they are part of a single algorithm. The chances that they might miscommunicate and collide are therefore far smaller. And if the Ministry of Transport decides to change some traffic regulation, all self-driving vehicles can be easily updated at exactly the same moment, and barring some bug in the program, they will all follow the new regulation to the letter.4

  Similarly, if the World Health Organization identifies a new disease, or if a laboratory produces a new medicine, it is almost impossible to update all the human doctors in the world about these developments. In contrast, even if you have 10 billion AI doctors in the world – each monitoring the health of a single human being – you can still update all of them within a split second, and they can all communicate to each other their feedback on the new disease or medicine. These potential advantages of connectivity and updateability are so huge that at least in some lines of work it might make sense to replace all humans with computers, even if individually some humans still do a better job than the machines.

  You might object that by switching from individual humans to a computer network we will lose the advantages of individuality. For example, if one human doctor makes a wrong judgement, he does not kill all the patients in the world, and he does not block the development of all new medications. In contrast, if all doctors are really just a single system, and that system makes a mistake, the results might be catastrophic. In truth, however, an integrated computer system can maximise the advantages of connectivity without losing the benefits of individuality. You can run many alternative algorithms on the same network, so that a patient in a remote jungle village can access through her smartphone not just a single authoritative doctor, but actually a hundred different AI doctors, whose relative performance is constantly being compared. You don’t like what the IBM doctor told you? No problem. Even if you are stranded somewhere on the slopes of Kilimanjaro, you can easily contact the Baidu doctor for a second opinion.
