We’ll learn to live with AI: here’s how

AI might just help us with life’s dilemmas, if we are responsible.

Anxiety about algorithms is nothing new. Back in 2020, It was a bad summer for the public image of algorithms. ‘I am afraid your grades were almost derailed by a mutant algorithm’, the then Prime Minister told pupils at a school. No topic in higher education is more sensitive than who gets a place at which university, and the thought that unfair decisions might be based on an errant algorithm caused understandable consternation. That algorithms have been used for many decades with widespread acceptance for coping with examination issues ranging from individual ill health to study of the wrong set text by a whole school seems quietly to have slipped under the radar.

Algorithmic decision-making is not new. Go back thousands of years to Hebrew Deuteronomic law: if a man had sex with a woman who was engaged to be married to another man, then this was unconditionally a capital offence for the man. But for the woman it depended on the circumstances. If it occurred in a city, then she would be regarded as culpable, on the grounds that she should have screamed for help. But if it occurred in the open country, then she was presumed innocent, since however loudly she might have cried out there would have been no one to hear her. This is a kind of algorithmic justice: IF in city THEN woman guilty ELSE woman not guilty.

Artificial intelligence is undergoing a transition from classification to decision-making. Broad artificial intelligence, or artificial general intelligence (AGI), in which the machines set their own goals, is the subject of gripping movies and philosophical analysis. Experts disagree about whether or when AGI will be achieved. Narrow artificial intelligence (AI) is with us now, in the form of machine learning. Where previously computers were programmed to perform a task, now they are programmed to learn to perform a task.

We use machine learning in my laboratory in Oxford. We undertake research on solid state devices for quantum technologies such as quantum computing. We cool a device to 1/50 of a degree above absolute zero, which is colder than anywhere in the universe that we know of outside a laboratory, and put one electron into each region, which may be only 1/1000 the diameter of a hair on your head. We then have to tune up the very delicate quantum states. Even for an experienced researcher this can take several hours. Our ‘machine’ has learned how to tune our quantum devices in less than 10 minutes.

Students in the laboratory are now very reluctant to tune devices by hand. It is as if all your life you have been washing your shirts in the bathtub with a bar of soap. It may be tedious, but it is the only way to get your shirts clean, and you do it as cheerfully as you can … until one day you acquire a washing machine, so that all you have to do is put in the shirts and some detergent, shut the door and press the switch. You come back two hours later, and your shirts are clean. You never want to go back to washing them in the bathtub with a bar of soap. And no one wants to go back to doing experiments without the machine. In my laboratory the machine decides what the next measurement will be.

Suppose that a machine came to know my preferences better than I can articulate them myself. The best professionals can already do this in their areas of expertise, and good friends sometimes seem to know us better than we know ourselves.

Many tasks previously reserved for humans are now done by machine learning. Passport control at international airports uses machine learning for passport recognition. An experienced immigration officer who examines one passport per minute might have seen four million faces by the end of their career. The machines were trained on fifty million faces before they were put into service. No wonder they do well.

Extraordinary benefits are being seen in health care. There is now a growing number of diagnostic studies in which the machines outperform humans, for example, in screening ultrasound scans or radiographs. Which would you rather be diagnosed by? An established human radiologist, or a machine with demonstrated superior performance? To put it another way, would you want to be diagnosed by a machine that knew less than your doctor? Answer: ‘No!’ Well then, would you want to be diagnosed by a doctor who knew less than the machine? That’s more difficult. Perhaps the question needs to be changed. Would you prefer to be treated by a doctor without machine learning or by a doctor making wise use of machine learning?

If we want humans to be involved in decisions involving our health, how much more in decisions involving our liberty. But are humans completely reliable and consistent? A peer-reviewed study suggested that the probability of a favourable parole decision depended on whether the judges had had their lunch. The very fact that appeals are sometimes successful provides empirical evidence that law, like any other human endeavour, involves uncertainty and fallibility. When it became apparent that in the UK there was inconsistency in sentencing for similar offences, in what the press called a postcode lottery, the Sentencing Council for England and Wales was established to promote greater transparency and consistency in sentencing. The code sets out factors which judges must consider in passing sentence, and ranges of tariffs for different kinds of crimes. If you like, it is another step in algorithmic sentencing. Would you want a machine that is less consistent than a judge to pass sentence? See the sequence of questions above about a doctor.

We may consider that judicial sentencing has a special case for human involvement because it involves restricting an individual’s freedom. What about democracy? How should citizens decide how to vote when given the opportunity? Voter A may prioritise public services, and she may seek to identify the party (if the choices are between well identified parties) which will best promote education, health, law and order, and other services which she values. She may also have a concern for the poor and favour redistributive taxation. Voter B may have different priorities and seek simply to vote for the party which in his judgement will leave him best off. Other factors may come into play, such as the perceived trustworthiness of an individual candidate, or their ability to evoke empathy from fellow citizens.

This kind of dilemma is something machines can help with, because they are good at multi-objective optimisation. A semiconductor industry might want chips that are as small as possible, and as fast as possible, and consume as little power as possible, and are as reliable as possible, and as cheap to manufacture as possible, but these requirements are in tension with one another. Techniques are becoming available to enable machines to make optimal decisions in such situations, and they may be better at them than humans. Suppose that a machine came to know my preferences better than I can articulate them myself. The best professionals can already do this in their areas of expertise, and good friends sometimes seem to know us better than we know ourselves. Suppose also that the machine was better than me at analysing which candidate if elected would be more likely to deliver the optimal combination of my preferences. Might there be something to be said for benefitting from that guidance?

If we get it right, the technologies of the machine learning age will provide new opportunities for Homo fidelis to promote human flourishing at its best.

By this point you may be sucking air through your intellectual teeth. You may be increasingly alarmed about machines taking decisions that should be reserved for humans. What are the sources of such unease? One may be that, at least in deep neural networks, the decisions that machines make may be only as good as the data on which they have been trained. If a machine has learned from data in which black people have an above average rate of recidivism, then black people may be disadvantaged in parole decisions taken by the machine. But this is not an area in which humans are perfect; that is why we have hidden bias training. In the era of Black Lives Matter we scarcely need reminding that humans are not immune to prejudice.

Another source of unease may be the use to which machine learning is put for commercial and political ends. If you think that machine learning is not already being applied to you, you are probably mistaken. Almost every time you do an online search or use social media, the big data companies are harvesting your data exhaust for their own ends. Even if your phone calls and emails are secure, they still generate metadata. European legislation is better than most, and the Online Safety Act 2023 will make the use of Internet services safer for individuals in the United Kingdom. But there is a limit to what regulation can protect, and 2024 is likely to see machine learning powerfully deployed to sway voters in elections in half the world. Targeted persuasion predates AI, as Othello’s Iago knew, but machine learning has brought it to an unprecedented level of industrialisation, with some of the best minds in the world paid some of the highest salaries in the world to maximise the user’s screen time and the personalisation of commercial and political influence.

Need it be so? In some ways advances in machine learning are acting as the canary in the mine, alerting us to fundamental questions about what humans are for, and what it means to be human. The old model of Homo economicus—rational, selfish, greedy, lazy man—has passed its sell-by date. It is being replaced by what I like to call Homo fidelis—ethical, caring, generous, energetic woman and man. For as long as AGI remains science fiction, it is up to humans to determine what values the machines are to implement. If we get it right, the technologies of the machine learning age will provide new opportunities for Homo fidelis to promote human flourishing at its best.

Whatever the future capabilities of machines, they cannot be morally load-bearing because humans are self-aware and mortal, whereas machines are not.

Paul Collier and John Kay

Christians have been thinking about what it means to be human for two millennia, building on what came before, and so they ought to have something to contribute to how humans flourish. In It Keeps Me Seeking, my co-authors and I ask our readers to imagine that they were writing about three thousand years ago for people who knew nothing of modern genetics or psychological science about what it means to be human. ‘You are writing for a storytelling culture, and so you would probably put it in the form of a story. Let’s say you set it in a garden. The garden is pleasant, but it is also designed for character formation, and so there is work to do, and also the possibility for a hard moral choice. You want to convey that humans need social interactions (for the same reason that solitary confinement is a severe punishment), and so you try the literary thought experiment of having one solitary man and letting him encounter animals and name them. Animals can be useful and they can be good company. But ultimately no animals, not even a dog, are fully satisfactory as partners in work and companions in life. Humans need humans. An enriching component of human relationships is sex. So, the supreme gift to the solitary man in our story is companionship with an equal who is both like and unlike; a woman. It is hardly a complete account, but it is a good start. Oh, and there is one other aspect. They should be free of the shame which lies at the root of so much psychological disorder.’

As far as it goes, would you regard such an account as complete? If not, what would you add next? You can see where this is going. To be human you need to be responsible. So, you let the humans face the moral choice. You can even include an element of disinformation to make the choice harder. And then when it goes horribly wrong you let them discover that they are responsible for their actions, and that blaming one another does not help. If you have God in your story, then (uniquely for the humans) responsibility consists of accountability to God. This is how human distinctiveness was addressed in early Jewish thought. As an early articulation that to be human means to be responsible, the story of Adam and Eve is unsurpassed.

In Greed is Dead, Paul Collier and John Kay reference Citizenship in a Networked Age as brilliantly elucidating the issue of morally pertinent decision-taking. They write, ‘Whatever the future capabilities of machines, they cannot be morally load-bearing because humans are self-aware and mortal, whereas machines are not. Machines can be used not only to complement and enhance human decision-making, but for bad: search optimisation has already morphed into influence-optimisation. We must keep morally pertinent decision-taking firmly in the domain of humanity.’

The nature of humanity includes responsibility—for wise use of machine learning and much more besides. Accountability is part of life for people with widely differing philosophical, ethical, and religious world views. If we are willing to concede that accountability follows responsibility, then we should next ask, ‘Accountable to whom?’

The plots and plotters that hold us spellbound

What happens when Americans lose faith in their religious institutions—and politicians fill the void? In Spellbound: How Charisma Shaped American History from the Puritans to Donald Trump, Molly Worthen sweeping history helps us understand the forces that create leaders and hold their followers captive.

Everyone feels it. Cultural and political life in America has become unrecognizable and strange. Firebrands and would-be sages have taken the place of reasonable and responsible leaders. Nuanced debates have given way to the smug confidence of yard signs. Worthen asks just how did we get here?

Worthen, a historian argues that we will understand the present moment if we learn the story of charisma in America. From the Puritans and Andrew Jackson to Black nationalists and Donald Trump, the saga of American charisma stars figures who possess a dangerous and alluring power to move crowds. They invite followers into a cosmic drama that fulfils hopes and rectifies grievances—and these charismatic leaders insist that they alone plot the way.

Author and historian Tom Holland loved this book.

“The great story of charisma in American history, from the Massachusetts Bay Colony to MAGA, has never been more thrillingly told, never more learnedly explicated.”

In this extract, entitled Plotlines, Worthen introduces her four categories of charismatic leader: Prophets. Conquerors, Agitators, and Gurus.

Plotlines

Over the past several years, whenever I told friends or family that I was writing a book about charisma, they responded with a reasonable question. Which charismatic figures would I include? They peppered me with suggestions: What about Elvis Presley, or Dolly Parton? Michael Jordan or Muhammad Ali? Surely I had to say something about Taylor Swift, right?

None of these fascinating people appears in this book. As you read it, you will probably think of a dozen others whom you wish I had included, and I’m sure you’ll have a point. I have mostly stuck to individuals who worked to build a movement in organized religion or politics, rather than musicians, artists, or athletes. Even within the spheres of religion and politics, I’ve been selective in order to craft a manageable story and bring into focus the patterns and transformations of charismatic leadership over the course of American history.

Sometimes this is an inspiring story, because charismatic leaders often turn up—and people decide to follow—out of a desperate response to alienation and injustice. People in anguish seek a savior. Yet charisma has no fixed moral standing. It can carve a path to freedom or to enslavement; it can lead people to embrace the rule of law or to sneer at it. Charisma causes problems for democracy as well as for authoritarian regimes. Without a sustained analysis of charisma over the long haul of American history since European settlement began, we are doomed to bumble along, blandly observing that ordinary people declare many allegiances that seem to contradict their own material interests and sabotage democracy—but never understanding why.

Over the past four centuries, five types of charismatic leaders have surged to dominance, each offering a variation on the great paradox, a different way for followers to hand over control while feeling liberated. I use these categories both to classify leaders and their movements, and to chart historical change: each type reacts to the type that came before, and responds to the pressures and anxieties of its own era. Like all typologies, this one maps imperfectly onto real people. Almost no one is a “pure” example of these categories, and some leaders are interesting precisely because they react against their age’s dominant type. But these categories have compelled even leaders who defied easy labels—that’s most of them—to respond to the ascendant charismatic style of their age.

The Prophets take us from the end of the Middle Ages into something beginning to resemble our own world. They drew on ancient patterns of contact with the divine to challenge authorities and captivate followers with the terror and ecstasy of God’s presence. They hewed close to tradition, operating in a time when Old World strictures still constrained life in the New World rather tightly. But some used those traditions to undermine reigning institutions, whether by violent rebellion or illicit gatherings—and so provoked a backlash. If the Prophets conceived of freedom in terms of divine salvation, they often harnessed mystical power for this-worldly ends. Usually this meant dismantling any structure that stood in God’s way.

The Prophets were, essentially, destroyers. In their wake they provoked an age of builders.

The Conquerors rose to prominence in the early nineteenth century—an age of mythology, mass media, and frontier enthusiasm in the European American imagination. They swung away from the age of the Prophets, who had so much to say about how powerless humans are.

Some of the Conquerors wielded military power, but all of them pursued what we might call metaphysical conquest. They fought to control spiritual forces. As the predestinarian Puritanism of earlier generations lost its appeal, more people placed an almost fundamentalist faith in the power of free will. It was tempting to think of spiritual forces—perhaps even the Holy Spirit— as a kind of technology, ready for manipulation. The stakes in these campaigns were high at a time when new advances in science impinged on everyday life. Waves of immigration made the country more religiously and ethnically diverse. Americans felt both freer and yet more confined than ever before.

The Agitators gained sway at the turn of the twentieth century, protesting modernity as a raw deal and democracy as tyranny in disguise. The Conquerors had, overall, expanded government authority over Americans’ lives and advanced a golden idea of progress. Now the pendulum swung back toward calls for destruction. The Agitators found a market for attacking the state and denouncing so-called progress as a lie. They defined themselves as outsiders whether they were or not, and discovered that gaining material power does not mean that one must stop telling a story of exile and affliction. This proved to be an important lesson in an age of world war and economic disaster: global crises have a way of transfiguring an outcast dissenter into a credible threat tot he standing order. Meanwhile, Christians grew wilder in their displays of New Testament charisma—because, paradoxically, it was easier to grapple with what Max Weber called the “iron cage” of modernity by embracing ever more outlandish signs of divine power.

The Experts were, on the face of things, the Agitators’ opposite in charismatic style. They were builders. In the wake of World War II, they capitalized on a backlash against the nightmare years of fascist demagogues, embraced the zenith of traditional institutions’ authority across Western culture and politics, and nurtured Americans’ faith in the power of technology and bureaucracy to solve large-scale problems.

They claimed the mantle of reason and procedure and did their best to relegate the political or religious clout of charisma to the distant past or primitive cultures.

But in fact, the three decades after World War II witnessed an explosion of religious revival in America—led by Christians who spoke in tongues, looked for the end times, and claimed to heal through the power of the Spirit. Even in the domain of credentialed and supposedly secular healing, the line between medicine and spirituality grew fuzzier. These years were the Experts’ apogee of cultural prestige, but Americans’ long- standing ambivalence about intellectual elites persisted. The most successful leaders capitalized on those mixed feelings. They nursed the tension between the Cold War celebration of science and freedom and, on the other hand, the lurking sense that technological leaps obscured eternal truths and needed the organizing power of a good story.

By the end of the twentieth century, as Americans lost faith in established media, churches, government, and nearly every other bulwark of modern society, the destructive strain of charismatic leadership re-surfaced in the form of the Gurus: preachers of self-actualization and get-enlightened-quick schemes, promoting God’s new temp job as personal assistant. Old-fashioned Pentecostal revival persisted too, but its leaders struggled to prevent the culture wars from capturing the Holy Spirit.

The Gurus looked, at first glance, like the Prophets and the Agitators. But in the generations since those earlier eras, it had become harder to pay obeisance to tradition—which was just fine, since the erosion of institutions had weakened traditions anyway, and opened a path for Gurus to achieve more influence than their destructive predecessors. Religious and philosophical tradition, in the hands of the Gurus, was no longer a firm guide but a palette for painting illusions of independence. Sometimes they used it to depict a new reality impervious to fact-checkers.

“Guru,” which means “remover of darkness” in Sanskrit, was originally a religious term. But in the third decade of the twenty-first century, the most prominent guru in the country was a businessman named Donald Trump. Trump was not, personally, a paragon of conventional religious devotion. Yet his political career depended on a hunger among his most dedicated supporters that can only be called spiritual. Like so many relationships between charismatic leaders and their followers, it stumped and angered those on the outside. Against the backdrop of the American charismatic tradition, however, his success makes perfect sense.

How, then, did early modern mystics and Puritan heretics who heard the voice of the Holy Spirit give way to devotees at a modern presidential rally, jostling toward the candidate iPhone-first, praying for a selfie? By the early twenty-first century, most religious institutions in the West had declined into husks of their former authority—at least by the usual measures. Today commentators turn more than ever to materialist explanations for political dysfunction, polarization, and the culture’s general crisis of confidence. They cite growing social inequality, impassable disagreements on policy, persistent racism and xenophobia, evil automated forces lurking on the internet. All true—yet all insufficient accounts. If we define the religious impulse as a hunger for transcendent meaning and a reflex to worship, then it is a human instinct only slightly less basic than the need for food and shelter, and Americans are no less religious than they have ever been. They will always find a way to satisfy these desires, even if charisma carries them down strange and costly paths.
