Homo Deus

Though the details are therefore obscure, we can nevertheless be sure about the general direction of history. In the twenty-first century, the third big project of humankind will be to acquire for us divine powers of creation and destruction, and upgrade Homo sapiens into Homo deus. This third project obviously subsumes the first two projects, and is fuelled by them. We want the ability to reengineer our bodies and minds in order, above all, to escape old age, death and misery, but once we have it, who knows what else we might do with such ability? So we may well think of the new human agenda as consisting really of only one project (with many branches): attaining divinity.

Indeed, it is already happening right now, through innumerable mundane actions. Every day millions of people decide to grant their smartphone a bit more control over their lives or try a new and more effective antidepressant drug. In pursuit of health, happiness and power, humans will gradually change first one of their features and then another, and another, until they will no longer be human. No clear line separates healing from upgrading. Medicine almost always begins by saving people from falling below the norm, but the same tools and know-how can then be used to surpass the norm.

This is the paradox of historical knowledge. Knowledge that does not change behaviour is useless. But knowledge that changes behaviour quickly loses its relevance. The more data we have and the better we understand history, the faster history alters its course, and the faster our knowledge becomes outdated.

Each and every one of us has been born into a given historical reality, ruled by particular norms and values, and managed by a unique economic and political system. We take this reality for granted, thinking it is natural, inevitable and immutable. We forget that our world was created by an accidental chain of events, and that history shaped not only our technology, politics and society, but also our thoughts, fears and dreams. The cold hand of the past emerges from the grave of our ancestors, grips us by the neck and directs our gaze towards a single future. We have felt that grip from the moment we were born, so we assume that it is a natural and inescapable part of who we are. Therefore we seldom try to shake ourselves free, and envision alternative futures.

Due to an uncompromising humanist belief in the sanctity of human life, we keep people alive till they reach such a pitiful state that we are forced to ask, ‘What exactly is so sacred here?’ Due to similar humanist beliefs, in the twenty-first century we are likely to push humankind as a whole beyond its limits. The same technologies that can upgrade humans into gods might also make humans irrelevant. For example, computers powerful enough to understand and overcome the mechanisms of ageing and death will probably also be powerful enough to replace humans in any and all tasks.

Humans are algorithms that produce […] copies of themselves (like a vending machine which, if you press the right combination of buttons, produces another vending machine).

The algorithms controlling vending machines work through mechanical gears and electric circuits. The algorithms controlling humans work through sensations, emotions and thoughts. And exactly the same kind of algorithms control pigs, baboons, otters and chickens.

In the Garden of Eden myth, humans are punished for their curiosity and for their wish to gain knowledge. God expels them from Paradise. In the Garden of Woolsthorpe myth, nobody punishes Newton – just the opposite. Thanks to his curiosity humankind gains a better understanding of the universe, becomes more powerful and takes another step towards the technological paradise. Untold numbers of teachers throughout the world recount the Newton myth to encourage curiosity, implying that if only we gain enough knowledge, we can create paradise here on earth.

In fact, God is present even in the Newton myth: Newton himself is God. When biotechnology, nanotechnology and the other fruits of science ripen, Homo sapiens will attain divine powers and come full circle back to the biblical Tree of Knowledge. Archaic hunter-gatherers were just another species of animal. Farmers saw themselves as the apex of creation. Scientists will upgrade us into gods.

Hence the existence of souls cannot be squared with the theory of evolution. Evolution means change, and is incapable of producing everlasting entities. From an evolutionary perspective, the closest thing we have to a human essence is our DNA, and the DNA molecule is the vehicle of mutation rather than the seat of eternity. This terrifies large numbers of people, who prefer to reject the theory of evolution rather than give up their souls.

No other animal can stand up to us, not because they lack a soul or a mind, but because they lack the necessary imagination. Lions can run, jump, claw and bite. Yet they cannot open a bank account or file a lawsuit. And in the twenty-first century, a banker who knows how to file a lawsuit is far more powerful than the most ferocious lion in the savannah.

Animals such as wolves and chimpanzees live in a dual reality. On the one hand, they are familiar with objective entities outside them, such as trees, rocks and rivers. On the other hand, they are aware of subjective experiences within them, such as fear, joy and desire. Sapiens, in contrast, live in triple layered reality. In addition to trees, rivers, fears and desires, the Sapiens world also contains stories about money, gods, nations and corporations. As history unfolded, the impact of gods, nations and corporations grew at the expense of rivers, fears and desires. There are still many rivers in the world, and people are still motivated by their fears and wishes, but Jesus Christ, the French Republic and Apple Inc. have dammed and harnessed the rivers, and have learned to shape our deepest anxieties and yearnings.

Human cooperative networks usually judge themselves by yardsticks of their own invention, and not surprisingly, they often give themselves high marks. In particular, human networks built in the name of imaginary entities such as gods, nations and corporations normally judge their success from the viewpoint of the imaginary entity. A religion is successful if it follows divine commandments to the letter; a nation is glorious if it promotes the national interest; and a corporation thrives if it makes a lot of money.

Fiction isn’t bad. It is vital. Without commonly accepted stories about things like money, states or corporations, no complex human society can function. We can’t play football unless everyone believes in the same made-up rules, and we can’t enjoy the benefits of markets and courts without similar make-believe stories. But stories are just tools. They shouldn’t become our goals or our yardsticks. When we forget that they are mere fiction, we lose touch with reality. Then we begin entire wars ‘to make a lot of money for the corporation’ or ‘to protect the national interest.’ Corporations, money and nations exist only in our imagination. We invented them to serve us; why do we find ourselves sacrificing our lives in their service?

Liberals, communists and followers of other modern creeds dislike describing their own system as a ‘religion’, because they identify religion with superstitions and supernatural powers. If you tell communists or liberals that they are religious, they think you accuse them of blindly believing in groundless pipe dreams. In fact, it means only that they believe in some system of moral laws that wasn’t invented by humans, but which humans must nevertheless obey. As far as we know, all human societies believe in this. Every society tells its members that they must obey some superhuman moral law, and that breaking this law will result in catastrophe.

We often associate science with the values of secularism and tolerance. If so, early modern Europe is the last place you would have expected a scientific revolution. Europe in the days of Columbus, Copernicus and Newton had the highest concentration of religious fanatics in the world, and the lowest level of tolerance. The luminaries of the Scientific Revolution lived in a society that expelled Jews and Muslims, burned heretics wholesale, saw a witch in every cat-loving elderly lady and started a new religious war every full moon.

This obsession with growth may sound self-evident, but only because we live in the modern world. It wasn’t like this in the past. Indian maharajas, Ottoman sultans, Kamakura shoguns and Han emperors seldom staked their political fortunes on ensuring economic growth. That Modi, Erdoğan, Abe and Chinese president Xi Jinping all bet their careers on economic growth testifies to the almost religious status growth has managed to acquire throughout the world. Indeed, it may not be wrong to call the belief in economic growth a religion, because it now purports to solve many if not most of our ethical dilemmas. Since economic growth is allegedly the source of all good things, it encourages people to bury their ethical disagreements and adopt whichever course of action maximises long-term growth.

How rational is it to risk the future of humankind on the assumption that future scientists will make some unknown discoveries? Most of the presidents, ministers and CEOs who run the world are very rational people. Why are they willing to take such a gamble? Maybe because they don’t think they are gambling on their own personal future. Even if bad comes to worse and science cannot hold off the deluge, engineers could still build a hi-tech Noah’s Ark for the upper caste, while leaving billions of others to drown. The belief in this hi-tech Ark is currently one of the biggest threats to the future of humankind and of the entire ecosystem. People who believe in the hi-tech Ark should not be put in charge of the global ecology, for the same reason that people who believe in a heavenly afterlife should not be given nuclear weapons.

The fact remains that humankind is today not only far more powerful than ever, it is also far more peaceful and cooperative. How did humans manage that? How did morality, beauty and even compassion survive and flourish in a world devoid of gods, of heaven and of hell?

Capitalists are, again, quick to give all the credit to the invisible hand of the market. Yet the market’s hand is blind as well as invisible, and by itself could never have saved human society. Indeed, not even a country fair can maintain itself without the helping hand of some god, king or church. If everything is for sale, including the courts and the police, trust evaporates, credit vanishes and business withers. What, then, rescued modern society from collapse? Humankind was salvaged not by the law of supply and demand, but rather by the rise of a new revolutionary religion—humanism.

The antidote to a meaningless and lawless existence was provided by humanism, a revolutionary new creed that conquered the world during the last few centuries. The humanist religion worships humanity, and expects humanity to play the part that God played in Christianity and Islam, and that the laws of nature played in Buddhism and Daoism. Whereas traditionally the great cosmic plan gave meaning to the life of humans, humanism reverses the roles, and expects the experiences of humans to give meaning to the great cosmos. According to humanism, humans must draw from within their inner experiences not only the meaning of their own lives, but also the meaning of the entire universe. This is the primary commandment humanism has given us: create meaning for a meaningless world.

If I believe in God at all, it is my choice to believe. If my inner self tells me to believe in God – then I believe. I believe because I feel God’s presence, and my heart tells me He is there. But if I no longer feel God’s presence, and if my heart suddenly tells me that there is no God – I will cease believing. Either way, the real source of authority is my own feelings. So even while saying that I believe in God, the truth is I have a much stronger belief in my own inner voice.

We see, then, that the self too is an imaginary story, just like nations, gods and money. Each of us has a sophisticated system that throws away most of our experiences, keeps only a few choice samples, mixes them up with bits from movies we saw, novels we read, speeches we heard, and from our own daydreams, and weaves out of all that jumble a seemingly coherent story about who I am, where I came from and where I am going. This story tells me what to love, whom to hate and what to do with myself. This story may even cause me to sacrifice my life, if that’s what the plot requires. We all have our genre. Some people live a tragedy, others inhabit a never-ending religious drama, some approach life as if it were an action film, and not a few act as if in a comedy. But in the end, they are all just stories.

However, we are on the brink of a momentous revolution. Humans are in danger of losing their value, because intelligence is decoupling from consciousness.

Until today, high intelligence always went hand in hand with a developed consciousness. Only conscious beings could perform tasks that required a lot of intelligence – such as playing chess, driving cars, diagnosing diseases or identifying terrorists. However, we are now developing new types of non-conscious intelligence that can perform such tasks far better than humans. This raises a novel question: which is really important – intelligence or consciousness? As long as they went hand in hand, debating their relative value was just a pastime for philosophers. But in the twenty-first century, this is becoming an urgent political and economic issue. And it is sobering to realise that, at least for armies and corporations, the answer is straightforward: intelligence is mandatory but consciousness is optional.

In the twenty-first century we might witness the creation of a massive new unworking class: people devoid of any economic, political or even artistic value, who contribute nothing to the prosperity, power and glory of society. This ‘useless class’ will not merely be unemployed — it will be unemployable. The crucial problem isn’t creating new jobs. The crucial problem is creating new jobs that humans perform better than algorithms.

Despite all the talk of radical Islam and Christian fundamentalism, the most interesting place in the world from a religious perspective is not the Islamic State or the Bible Belt, but Silicon Valley. That’s where hi-tech gurus are brewing for us brave new religions that have little to do with God, and everything to do with technology. They promise all the old prizes – happiness, peace, prosperity and even eternal life – but here on earth with the help of technology, rather than after death with the help of celestial beings.

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.

Dataism declares that the universe consists of data flows, and the value of any phenomenon or entity is determined by its contribution to data processing. Dataism thereby collapses the barrier between animals and machines, and expects electronic algorithms to eventually decipher and outperform biochemical algorithms. 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.

Like capitalism, Dataism too began as a neutral scientific theory, but is now mutating into a religion that claims to determine right and wrong. The supreme value of this new religion is ‘information flow’. If life is the movement of information, and if we think that life is good, it follows that we should extend, deepen and spread the flow of information in the universe. According to Dataism, human experiences are not sacred and Homo sapiens isn’t the apex of creation or a precursor of some future Homo deus. Humans are merely tools for creating the Internet-of-All-Things, which may eventually spread out from planet Earth to cover the whole galaxy and even the whole universe. This cosmic data-processing system would be like God. It will be everywhere and will control everything, and humans are destined to merge into it.
