Did the decline in our capacity to smell, to pay attention and to dream make our lives poorer and greyer? Maybe. But even if it did, for the economic and political system it was worth it. Mathematical skills are more important to the economy than smelling flowers or dreaming about fairies. For similar reasons, it is likely that future upgrades to the human mind will reflect political needs and market forces.
For example, the US army’s ‘attention helmet’ is meant to help people focus on well-defined tasks and speed up their decision-making process. It may, however, reduce their ability to show empathy and tolerate doubts and inner conflicts. Humanist psychologists have pointed out that people in distress often don’t want a quick fix – they want somebody to listen to them and sympathise with their fears and misgivings. Suppose you are having an ongoing crisis in your workplace, because your new boss doesn’t appreciate your views, and insists on doing everything her way. After one particularly unhappy day, you pick up the phone and call a friend. But the friend has little time and energy for you, so he cuts you short, and tries to solve your problem: ‘Okay. I get it. Well, you really have just two options here: either quit the job, or stay and do what the boss wants. And if I were you, I would quit.’ That would hardly help. A really good friend will have patience, and will not be quick to find a solution. He will listen to your distress, and will provide time and space for all your contradictory emotions and gnawing anxieties to surface.
The attention helmet works a bit like the impatient friend. Of course sometimes – on the battlefield, for instance – people need
to take firm decisions quickly. But there is more to life than that. If we start using the attention helmet in more and more situations, we may end up losing our ability to tolerate confusion, doubts and contradictions, just as we have lost our ability to smell, dream and pay attention. The system may push us in that direction, because it usually rewards us for the decisions we make rather than for our doubts. Yet a life of resolute decisions and quick fixes may be poorer and shallower than one of doubts and contradictions.
When you mix a practical ability to engineer minds with our ignorance of the mental spectrum and with the narrow interests of governments, armies and corporations, you get a recipe for trouble. We may successfully upgrade our bodies and our brains, while losing our minds in the process. Indeed, techno-humanism may end up
downgrading
humans. The system may prefer downgraded humans not because they would possess any superhuman knacks, but because they would lack some really disturbing human qualities that hamper the system and slow it down. As any farmer knows, it’s usually the brightest goat in the herd that stirs up the greatest trouble, which is why the Agricultural Revolution involved downgrading animal mental abilities. The second cognitive revolution dreamed up by techno-humanists might do the same to us.
The Nail on Which the Universe Hangs
Techno-humanism faces another dire threat. Like all humanist sects, techno-humanism too sanctifies the human will, seeing it as the nail on which the entire universe hangs. Techno-humanism expects our desires to choose which mental abilities to develop, and to thereby determine the shape of future minds. Yet what would happen once technological progress makes it possible to reshape and engineer our desires themselves?
Humanism always emphasised that it is not easy to identify our authentic will. When we try to listen to ourselves, we are often flooded by a cacophony of conflicting noises. Indeed, we sometimes don’t really want to hear our authentic voice, because it can
disclose unwelcome secrets and make uncomfortable requests. Many people take great care not to probe themselves too deeply. A successful lawyer on the fast track may stifle an inner voice telling her to take a break and have a child. A woman trapped in a dissatisfying marriage fears losing the security it provides. A guilt-ridden soldier is stalked by nightmares about atrocities he committed. A young man unsure of his sexuality follows a personal ‘don’t ask, don’t tell’ policy. Humanism doesn’t think any of these situations has an obvious one-size-fits-all solution. But humanism demands that we show some guts, listen to the inner messages even if they scare us, identify our authentic voice and then follow its instructions regardless of the difficulties.
Technological progress has a very different agenda. It doesn’t want to listen to our inner voices. It wants to control them. Once we understand the biochemical system producing all these voices, we can play with the switches, turn up the volume here, lower it there, and make life much more easy and comfortable. We’ll give Ritalin to the distracted lawyer, Prozac to the guilty soldier and Cipralex to the dissatisfied wife. And that’s just the beginning.
Humanists are often appalled by this approach, but we had better not pass judgement on it too quickly. The humanist recommendation to listen to ourselves has ruined the lives of many a person, whereas the right dosage of the right chemical has greatly improved the well-being and relationships of millions. In order to really listen to themselves, some people must first turn down the volume of the inner screams and diatribes. According to modern psychiatry, many ‘inner voices’ and ‘authentic wishes’ are nothing more than the product of biochemical imbalances and neurological diseases. People suffering from clinical depression repeatedly walk out on promising careers and healthy relationships because some biochemical glitch makes them see everything through dark-coloured lenses. Instead of listening to such destructive inner voices, it might be a good idea to shut them up. When Sally Adee used the attention helmet to silence the voices in her head, she not only became an expert markswoman, but she also felt much better about herself.
Personally, you may have many different views about these issues. Yet from a historical perspective it is clear that something momentous is happening. The number one humanist commandment – listen to yourself! – is no longer self-evident. As we learn to turn our inner volume up and down, we give up our belief in authenticity, because it is no longer clear whose hand is on the switch. Silencing annoying noises inside your head seems like a wonderful idea, provided it enables you to finally hear your deep authentic self. But if there is no authentic self, how do you decide which voices to silence and which to amplify?
Let’s assume, just for the sake of argument, that within a few decades brain scientists will give us easy and accurate control over many inner voices. Imagine a young gay man from a devout Mormon family, who after years of living in the closet has finally accumulated enough money to finance a passion operation. He goes to the clinic armed with $100,000, determined to walk out of it as straight as Joseph Smith. Standing in front of the clinic’s door, he mentally repeats what he is going to say to the doctor: ‘Doc, here’s $100,000. Please fix me so that I will never want men again.’ He then rings the bell, and the door is opened by a real-life George Clooney. ‘Doc,’ mumbles the overwhelmed lad, ‘here’s $100,000. Please fix me so that I will never want to be straight again.’
Did the young man’s authentic self win over the religious brainwashing he underwent? Or perhaps a moment’s temptation caused him to betray himself? And perhaps there is simply no such thing as an authentic self that you can follow or betray? Once people could design and redesign their will, we could no longer see it as the ultimate source of all meaning and authority. For no matter what our will says, we can always make it say something else.
According to humanism, only human desires imbue the world with meaning. Yet if we could choose our desires, on what basis could we possibly make such choices? Suppose
Romeo and Juliet
opened with Romeo having to decide with whom to fall in love. And suppose even after making a decision, Romeo could always retract and make a different choice instead. What kind of play
would it have been? Well, that’s the play technological progress is trying to produce for us. When our desires make us uncomfortable, technology promises to bail us out. When the nail on which the entire universe hangs is pegged in a problematic spot, technology would pull it out and stick it somewhere else. But where exactly? If I could peg that nail anywhere in the cosmos, where should I peg it, and why there of all places?
Humanist dramas unfold when people have uncomfortable desires. For example, it is extremely uncomfortable when Romeo of the house of Montague falls in love with Juliet of the house of Capulet, because the Montagues and Capulets are bitter enemies. The technological solution to such dramas is to make sure we never have uncomfortable desires. How much pain and sorrow would have been avoided if instead of drinking poison, Romeo and Juliet could just take a pill or wear a helmet that would have redirected their star-crossed love towards other people.
Techno-humanism faces an impossible dilemma here. It considers the human will to be the most important thing in the universe, hence it pushes humankind to develop technologies that can control and redesign our will. After all, it’s tempting to gain control over the most important thing in the world. Yet once we have such control, techno-humanism would not know what to do with it, because the sacred human will would become just another designer product. We can never deal with such technologies as long as we believe that the human will and the human experience are the supreme source of authority and meaning.
Hence a bolder techno-religion seeks to sever the humanist umbilical cord altogether. It foresees a world which does not revolve around the desires and experiences of any humanlike beings. What might replace desires and experiences as the source of all meaning and authority? As of 2016, only one candidate is sitting in history’s reception room waiting for the job interview. This candidate is information. The most interesting emerging religion is Dataism, which venerates neither gods nor man – it worships data.
Dataism says that the universe consists of data flows, and the value of any phenomenon or entity is determined by its contribution to data processing.

This may strike you as some eccentric fringe notion, but in fact it has already conquered most of the scientific establishment. Dataism was born from the explosive confluence of two scientific tidal waves. In the 150 years since Charles Darwin published
On the Origin of Species
, the life sciences have come to see organisms as biochemical algorithms. Simultaneously, in the eight decades since Alan Turing formulated the idea of a Turing Machine, computer scientists have learned to engineer increasingly sophisticated electronic algorithms. Dataism puts the two together, pointing out that exactly the same mathematical laws apply to both biochemical and electronic algorithms. Dataism thereby collapses the barrier between animals and machines, and expects electronic algorithms to eventually decipher and outperform biochemical algorithms.
For politicians, business people and ordinary consumers, Dataism offers groundbreaking technologies and immense new powers. For scholars and intellectuals it also promises to provide the scientific holy grail that has eluded us for centuries: a single overarching theory that unifies all the scientific disciplines from literature and musicology to economics and biology. According
to Dataism,
King Lear
and the flu virus are just two patterns of data flow that can be analysed using the same basic concepts and tools. This idea is extremely attractive. It gives all scientists a common language, builds bridges over academic rifts and easily exports insights across disciplinary borders. Musicologists, political scientists and cell biologists can finally understand each other.
In the process, Dataism inverts the traditional pyramid of learning. Hitherto, data was seen as only the first step in a long chain of intellectual activity. Humans were supposed to distil data into information, information into knowledge, and knowledge into wisdom. However, Dataists believe that humans can no longer cope with the immense flows of data, hence they cannot distil data into information, let alone into knowledge or wisdom. The work of processing data should therefore be entrusted to electronic algorithms, whose capacity far exceeds that of the human brain. In practice, this means that Dataists are sceptical about human knowledge and wisdom, and prefer to put their trust in Big Data and computer algorithms.
Dataism is most firmly entrenched in its two mother disciplines: computer science and biology. Of the two, biology is the more important. It was the biological embracement of Dataism that turned a limited breakthrough in computer science into a world-shattering cataclysm that may completely transform the very nature of life. You may not agree with the idea that organisms are algorithms, and that giraffes, tomatoes and human beings are just different methods for processing data. But you should know that this is current scientific dogma, and that it is changing our world beyond recognition.
Not only individual organisms are seen today as data-processing systems, but also entire societies such as beehives, bacteria colonies, forests and human cities. Economists increasingly interpret the economy, too, as a data-processing system. Laypeople believe that the economy consists of peasants growing wheat, workers manufacturing clothes, and customers buying bread and underpants. Yet experts see the economy as a mechanism for
gathering data about desires and abilities, and turning this data into decisions.
According to this view, free-market capitalism and state-controlled communism aren’t competing ideologies, ethical creeds or political institutions. At bottom, they are competing data-processing systems. Capitalism uses distributed processing, whereas communism relies on centralised processing. Capitalism processes data by directly connecting all producers and consumers to one another, and allowing them to exchange information freely and make decisions independently. For example, how do you determine the price of bread in a free market? Well, every bakery may produce as much bread as it likes, and charge for it as much as it wants. The customers are equally free to buy as much bread as they can afford, or take their business to the competitor. It isn’t illegal to charge $1,000 for a baguette, but nobody is likely to buy it.
