A Brief History of Money

1. The Invention and Purpose of Money

Money is not a material discovery in the traditional sense, but rather a mental revolution. 

It is an intersubjective reality that exists only in the collective imagination of people. 

This collective agreement makes it possible to systematically represent values, which greatly simplifies the comparison of goods and services and their exchange. 

It also serves as a practical means of storing value over long periods of time.

The introduction of money freed specialized workers from the constraints of barter. In barter, it was often difficult to find a partner who had exactly what you needed and at the same time wanted exactly what you had to offer. 

Money overcomes this "double coincidence of wants" by providing a universal medium of exchange.

Throughout history, many different items have served as money: from cowrie shells to cattle, hides, salt, grain, and pearls to promissory notes. 

Even in modern times, such as in prisons or prisoner-of-war camps, everyday items such as cigarettes have functioned as currency. 

What matters is not the intrinsic value of these objects, but the trust that people place in them.

This trust is the fundamental basis of money. It is based on a complex web of political, social, and economic relationships. People accept money because they trust that others—including government institutions that levy taxes in that currency—will also accept it and recognize its value.

The development of money began with systems that had intrinsic value, such as Sumerian barley money around 3000 BC. However, the decisive advance came with forms of money that had little or no intrinsic value but were easier to store and transport, such as the silver shekel in Mesopotamia. 

Another milestone was the coins minted in the Kingdom of Lydia around 640 BC. They offered the advantage of a standardized weight and an official minting that came from an authority and guaranteed the content and weight of the coin. This minimized fraud and made transactions much more efficient and trustworthy.

2. Money and globalization: 

A universal language of trust

The spread of monetary systems, especially those based on precious metals such as gold and silver, played a decisive role in the creation of an increasingly interconnected global economic and political world. 

Despite the enormous diversity of languages, cultures, and political systems, a shared belief in the value of gold and silver enabled the emergence and growth of global trade networks.

Money has a unique ability to be universally exchangeable: in principle, it can transform anything into anything else—be it muscle power into intellectual work, health into justice, or material goods into intangible services. 

This universal exchangeability is inextricably linked to the universal trust that money creates. It enables strangers to cooperate effectively and smoothly with one another, even if they have never met before and have no personal connection. Money's ability to convey trust across cultural and geographical boundaries is a cornerstone of global interconnectedness.

The forces of supply and demand in global trade cause the value of transportable goods to converge in all connected areas. 

This, in turn, promotes the acceptance of the same forms of money across cultural boundaries. A merchant in China could do business with a merchant in Egypt because both trusted the value of silver or gold, even though they were completely different in language and religion.

3. The duality of money: 

light and shadow

Despite its enormous advantages and its role as a driver of cooperation and trade, the power of money also has a "dark side." 

It has the ability to undermine traditional customs, intimate relationships, and deeply rooted human values. By making everything expressible in numbers and thus purchasable, the cold laws of supply and demand can triumph over aspects of life that were traditionally considered "priceless."

This can lead to problematic incentives. When everything has a price, actions can be motivated that contradict values such as honor, loyalty, or love. 

Examples of this, according to Yuval Noah Harari's book "Money," range from parents selling their children to knights auctioning their loyalty to the highest bidder. 

There is a danger that the pursuit of monetary gain will shift or even remove moral and ethical boundaries.

Capitalism, as described in the book, is characterized by the principle of not simply hoarding or consuming profits, but reinvesting them to generate even greater profits. This is the fundamental difference between "capital" (productively invested money) and mere "wealth." 

Although the free market is often portrayed as the most efficient and wise economic policy, its unregulated mechanisms can lead to problems such as monopoly formation, wage dumping, and even historical atrocities, as the Atlantic slave trade demonstrates. 

Such developments are often the result of a blind pursuit of profit and growth without sufficient consideration of ethical and human consequences.

4. The Great Decoupling and the Future

The book also looks to the future and discusses the possible "great decoupling" that could be triggered by technological advances, particularly in artificial intelligence (AI). 

In a scenario where human labor is becoming increasingly redundant, fundamental questions arise about the role of humans in society. 

How can people be kept employed and satisfied when their labor is no longer needed? One possible answer could be an increased reliance on virtual realities, which could serve as a substitute for missing real-world tasks.

These developments also raise concerns about human individuality. If algorithms increasingly make important decisions for individuals—whether in healthcare, career choices, or personal relationships—this could erode personal authority and freedom. 

The book encourages reflection on the implications of a world in which human autonomy is challenged by data-driven algorithms.

Finally, the text highlights the future of medicine, which may no longer focus primarily on curing disease, but on "upgrading the healthy." As technologies for enhancing human capabilities become accessible, this could further deepen social disparities if such advances are not equitably distributed or regulated. 

The ability to enhance physical and mental attributes could lead to a new form of inequality based on biotechnological possibilities.

I. Introduction: Navigating the Landscape of Value and Progress

This report offers a comprehensive analysis of the evolution of money, the principles and historical impacts of capitalism, and the transformative potential of artificial intelligence on the future of humanity. It draws primarily from the profound insights of Yuval Noah Harari's "Money". 

As an interdisciplinary historian and futurist, this report will synthesize these complex societal, economic, and technological trends, providing a holistic perspective on how humanity has organized value and the challenges that lie ahead. 

The analysis will extend beyond Harari's core arguments, integrating supplementary research to illuminate contemporary examples, policy discussions, and the psychological and political dimensions of these ongoing transformations.

II. The Emergence and Psychology of Money: 

A Shared Imagination

This section explores the historical origins and fundamental nature of money, tracing its development from rudimentary exchange systems to its modern digital forms, and emphasizing its psychological underpinnings as a collective construct of trust.

From Favors and Barter to the Need for Universal Exchange

Early human societies, such as hunter-gatherer bands and early agricultural villages, primarily operated on an "economy of favours and obligations". Within these intimate communities, goods and services were shared with an implicit understanding of reciprocity. 

For instance, a piece of meat might be reciprocated with free medical assistance. Limited barter occurred only for rare items not locally available.

The advent of cities and kingdoms, coupled with improved transport infrastructure, fostered specialization. 

This led to the emergence of full-time professions like shoemakers, doctors, carpenters, priests, and lawyers in densely populated cities. This specialization, while economically beneficial, strained the old system. 

An economy of favors proved ineffective among a large number of strangers, and direct barter became cumbersome. Harari illustrates this with the example of an apple farmer trying to barter with a shoemaker, highlighting the immense complexity of calculating relative prices (e.g., 4,950 exchange rates for 100 commodities) and the inherent problem of the "double coincidence of wants". Attempts at centralized barter systems, such as the Soviet Union's failed experiment or the more moderate Inca Empire, demonstrated the difficulties and limited successes of such approaches.

The "Mental Revolution":

Money as Intersubjective Reality

Money was invented multiple times and places, representing a "purely mental revolution" and the creation of a "new inter-subjective reality" based on shared imagination.

Defined as anything people are willing to use to systematically represent the value of other things for the purpose of exchanging goods and services, money facilitates quick value comparison, easy exchange, and convenient wealth storage. Remarkably, today over 90% of the world's money exists as electronic data on computer servers, making physical cash a rare form. 

The most basic quality of money is its universal desirability: 

"Everyone always wants money because everyone else also always wants money". 

This universal acceptance allows money to function as a universal medium of exchange, capable of converting almost anything into almost anything else—from brawn into education (soldier's benefits for college tuition), land into loyalty, or health into justice (physician's fees for a lawyer). 

It also efficiently solves the problems of storing and transporting wealth, as abstract money (like cowry shells or digital bits) is durable, compact, and easy to move compared to perishable goods like grain or immovable assets like real estate.

The emphasis on money as a "purely mental revolution" and "intersubjective reality" underscores that it is not merely a medium of exchange but a fundamental shift in human cognition and social organization. 

This development enabled humans to cooperate on an unprecedented scale, transcending the limitations of small, intimate groups. The transition from favors and barter, limited by trust and the coincidence of needs, to money with its universal convertibility, storability, and transportability, demonstrates a societal need for scalable cooperation. The power of money lies not in its material form but in collective belief. 

This collective belief is a highly evolved form of social technology that enables complex economic systems otherwise unimaginable. The statement that money is the "apogee of human tolerance" is a direct consequence: money enables cooperation despite differences by providing a common, abstract denominator for value. This is a profound social innovation, demonstrating humanity's unique capacity for shared fictions to create complex realities.

Early Forms of Money: 

Barley, Silver, Shells, and Their Evolution

The first known money was Sumerian barley money, emerging around 3000 BC. Measured in fixed amounts (e.g., sila), barley had an intrinsic biological value (it was edible), which helped build initial trust. However, it was cumbersome to store and transport.

A significant breakthrough occurred with the silver shekel in ancient Mesopotamia (mid-third millennium BC), which possessed no intrinsic value but was easier to store and transport. Its value was purely cultural and associated with high social status. 

Other forms included cowry shells, used for 4,000 years across Africa, Asia, and Oceania, valued for their durability and portability. Even in modern prisons and POW camps, cigarettes served as a functional currency.

The Introduction of Coinage: 

Standardization, Trust, and Sovereignty

The first coins were struck around 640 BC by King Alyattes of Lydia. These were standardized, imprinted metal pieces that bore an identification mark indicating the precious metal content and guaranteed by the issuing authority.

Coins offered crucial advantages over unmarked metal ingots: 

they eliminated the need for weighing at each transaction and provided a purity guarantee that combated fraud. 

The mark on a coin was essentially the "signature of some political authority" , directly linking monetary value to state power. Counterfeiting was thus not merely fraud but a "breach of sovereignty," often severely punished. Trust in the king's power and integrity directly translated into trust in his coins. 

The king's signature on a coin was not just a guarantee of weight; it was an assertion of power and legitimacy. The ability to mint currency and demand it as taxes gave the state immense control over its population and economy. 

The acceptance of the Roman denarius far beyond the Roman Empire's borders demonstrates how economic trust can extend political influence and project soft power. 

This early intertwining of financial and political power foreshadows later discussions of capitalism's role in imperialism, where financial leverage directly translates into geopolitical dominance and control over resources and populations.

The "Gospel of Gold": 

Unifying the World Through Shared Belief

The trust in Rome's coins was so strong that even outside the empire's borders, people were happy to receive payment in denarii. 

The name "denarius" became generic for coins, leading to "dinars" in Muslim caliphates. While China developed a slightly different system (bronze coins, unmarked silver/gold ingots), the shared reliance on gold and silver allowed for close monetary and commercial relations between Chinese and Lydian zones. 

Muslim and European merchants spread the "gospel of gold," gradually unifying the entire world into a single monetary zone by the late modern era, relying first on gold and silver, then on trusted currencies like the British pound and American dollar.

This shared belief, even among diverse cultures with conflicting languages, rulers, and gods, was driven by the forces of supply and demand. If one region valued gold, merchants profited by buying it cheaply elsewhere and selling it dearly, eventually equalizing its value globally. Harari posits that money is the "apogee of human tolerance," capable of bridging almost any cultural gap and not discriminating based on religion, gender, race, age, or sexual orientation, thereby enabling effective cooperation among strangers.

The Duality of Money: 

Enabling Cooperation Versus Corroding Values

Despite its unifying power, money possesses a "dark side." 

Its principles of "universal convertibility" and "universal trust" can "corrode local traditions, intimate relations and human values," replacing them with the "cold laws of supply and demand". 

Things traditionally considered "priceless," such as honor, loyalty, morality, and love, can be drawn into the market sphere. Historical examples include parents selling children into slavery, Christians buying forgiveness for sins, ambitious knights auctioning their allegiance, and tribal lands being sold to foreigners. 

This implies a shift in trust: instead of trusting humans or communities, trust is invested in "money itself and in the impersonal systems that back it". If money runs out, trust dwindles, potentially leading to a "heartless marketplace".

While money builds trust, this trust is impersonal and can undermine personal, community-based trust. It is a system of "mutual trust" , but it is trust in the system, not necessarily in the individual. 

Harari explicitly states: 

"We do not trust the stranger, or the next-door neighbour – we trust the coin they hold. If they run out of coins, we run out of trust". 

This creates a fundamental tension. Money facilitates large-scale cooperation by abstracting trust from personal relationships, but in doing so, it can weaken the fabric of those relationships. 

The "cold laws of supply and demand" replace "priceless" human values. This is a subtle but critical trade-off: efficiency and scalability at the expense of communal feeling and inherent human worth. 

The implication is that while money enables vast networks, it also carries the risk of dehumanizing interactions by reducing them to transactional exchanges.

III. Capitalism: 

The Engine of Perpetual Growth and Its Historical Trajectory

This section illuminates capitalism as a dynamic economic system driven by the imperative of growth and credit, examining its historical role in empire-building and its profound, often ethically problematic, impacts on societies.

The Paradigm Shift: 

From Static Economies to Exponential Growth

For most of human history, the global economy remained relatively static, with per capita production largely constant. The modern age, however, witnessed "stupendous growth" , with global production of goods and services increasing from about $250 billion in 1500 to around $60 trillion today, and annual per capita production rising from $550 to $8,800. 

This unprecedented growth is attributed to the "idea of progress," which emerged with the Scientific Revolution and fostered the belief that human production, trade, and wealth could be increased indefinitely. This led to the fundamental capitalist conviction of a "growing global pie".

The Power of Credit: 

Building the Present on Future Abundance

Credit is presented as a special kind of money representing "imaginary goods"—resources or products that do not exist in the present but are anticipated in the future. 

It enables building the present at the expense of the future. In pre-modern times, credit was severely limited because people generally believed wealth was finite or dwindling, viewing economic interactions as a "zero-sum game". This led to small, short-term loans with high interest rates, hindering new enterprises.

The modern age's belief in progress transformed credit, making large, long-term, and low-interest loans widespread. Harari illustrates how banks create money through credit, lending far more than they physically possess (e.g., $10 for every $1 in vaults), with the entire system relying on "trust in the future profitability" of investments. 

The "magic circle of imperial capitalism" is a microcosm of the broader capitalist system. Trust in the future fuels credit, enabling ventures (exploration, production) that generate profits, which in turn build trust and translate into more credit. 

This highlights a powerful positive feedback loop fundamental to capitalism's sustained growth. The concept of "credit" as "imaginary goods" is crucial to understanding this cycle. It's not about existing wealth, but anticipated wealth, requiring a leap of faith. 

The historical shift from a "zero-sum game" mentality to a "growing global pie" was a necessary cultural and psychological prerequisite for this cycle to take hold. 

The examples of the Netherlands against Spain and Britain against France clearly demonstrate how financial trust (built on reliability and rule of law) directly translated into geopolitical and imperial power, illustrating the causal link between robust financial systems and global dominance. 

This cycle, while generating immense wealth, also inherently drives expansion and resource extraction to sustain the "pie's" growth.

Adam Smith's Revolutionary Ethic: Greed as a Collective Good

Adam Smith's "The Wealth of Nations" (1776) is identified as the foundational manifesto of the capitalist creed. Smith argued that the selfish pursuit of private profits ultimately benefits everyone by increasing collective wealth, famously implying that "greed is good" and "egoism is altruism". 

This perspective defined the economy as a "win-win situation," where individual profits contribute to a growing "overall pie".

A crucial ethical component of modern capitalism is the imperative that "profits of production must be reinvested in increasing production" ad infinitum. 

This distinguishes "capital" (money, goods, and resources invested in production) from mere "wealth" (hoarded or wasted on unproductive activities). Unlike medieval nobles who spent revenues on conspicuous consumption, the new capitalist elite (CEOs, stock traders, industrialists) prioritizes reinvestment over extravagance. 

Capitalism thus evolved from an economic theory into a comprehensive "ethic," viewing economic growth as the supreme good, upon which justice, freedom, and happiness depend.

The Symbiotic Relationship: 

Capitalism, Science, and Imperial Expansion

Modern science and capitalism are deeply intertwined. Scientific research is often funded based on its potential to increase production and profits. 

Conversely, capitalism's belief in perpetual growth relies on scientists continually making new discoveries and inventions. Harari warns that the stability of the current economic system, where governments print trillions of "make-believe money," depends on scientists creating "something really big" in fields like biotechnology and nanotechnology before a financial bubble bursts.

Capitalism also played a decisive role in the emergence of European imperialism. Unlike non-European empires that financed wars through taxes and plunder, European conquests were increasingly financed through credit and directed by capitalists seeking maximum returns on their investments. 

This created a "magic circle of imperial capitalism": credit financed new discoveries (like Columbus's voyages), leading to colonies, which provided profits, built trust, and translated into more credit. 

To mitigate the inherent risks of such ventures, Europeans developed "limited liability joint-stock companies," allowing numerous investors to risk small portions of their capital for potentially unlimited profits.

The rise of the Dutch Republic over the mighty Spanish Empire in the 16th century illustrates the power of credit. The Dutch secured the trust of the burgeoning European financial system through reliable loan repayment and an independent legal system that protected private property rights, drawing capital away from less stable states like Spain. 

Private joint-stock companies, such as the Vereenigde Oostindische Compagnie (VOC), financed vast military operations and conquered Indonesia, demonstrating how private entities built empires. Conversely, the "Mississippi Bubble" (1717-1720) in France serves as a cautionary tale. 

Manipulative stock prices, fueled by political connections and central bank money printing, led to a catastrophic financial collapse. 

This loss of public trust in the French financial system hindered its ability to raise credit and contributed to the rapid expansion of the British Empire, which, like the Dutch, was largely built by private joint-stock companies like the British East India Company.

The Perils of Unchecked Markets: 

Exploitation, Slavery, and Colonial Atrocities

Harari highlights a "dark side" of capitalism: the relentless pursuit of profit and growth that, if "unrestricted by any other ethical considerations, can easily lead to a catastrophe". 

He challenges Adam Smith's optimistic view, arguing that in a "completely free market, unsupervised by kings and priests, avaricious capitalists can establish monopolies or collude against their workforces," leading to exploitation through reduced wages, increased working hours, debt peonage, or even slavery.

The Atlantic slave trade is presented as a prime example of "unrestrained market forces". 

This was a "purely economic enterprise," organized and financed by the free market, with private slave-trading companies selling shares on European stock exchanges. 

Approximately 10 million African slaves were forcibly transported to the Americas, primarily for labor-intensive sugar plantations, where they endured "abominable" conditions and immense suffering, all driven by the pursuit of "huge profits". 

Harari unequivocally states: "Capitalism has killed millions out of cold indifference coupled with greed".

Other examples include the Great Bengal Famine, where the British East India Company prioritized profits over the lives of 10 million Bengalis , and the VOC's military campaigns in Indonesia, financed by Dutch citizens who "had no regard for the suffering" of the local population. 

King Leopold II's "humanitarian" organization in the Congo Free State quickly transformed into a ruthless business enterprise aimed at rubber extraction, leading to an estimated 6 to 10 million deaths through brutal exploitation.

Harari argues that Western governments often became a "capitalist trade union" , serving the interests of big capital. 

The First Opium War (1840-42) is cited as a "notorious example," where Britain declared war on China in the name of "free trade" to protect the lucrative opium exports of British drug merchants, leading to millions of Chinese addicts and British control over Hong Kong. Similarly, British investors' loans to Egypt led to British military intervention, and Egypt became a British protectorate. 

Even war itself became a commodity, as shown by the tradable Greek Rebellion Bonds, where the financial interests of British bondholders led to military intervention. 

This historical pattern underscores why a country's credit rating, which considers political and social factors, is more important for its economic well-being than its natural resources. 

Harari's sharp criticism of "cold indifference coupled with greed" leading to millions of deaths reveals a profound moral danger that arises when economic growth becomes the "supreme good". 

This suggests that the pursuit of profit, when unchecked by ethical or regulatory frameworks, can override fundamental human empathy and lead to systemic atrocities. 

The historical examples are not isolated cases of individual malice but systemic outcomes of market forces operating without sufficient external constraints. 

The argument that "capitalism has killed millions out of cold indifference coupled with greed" implies that the system itself, not just individual actors, can be responsible for widespread suffering. 

This points to a critical tension between capitalism's efficiency and wealth generation and its potential for immense human suffering when not balanced by robust ethical and regulatory oversight. 

The "cult of the free market" is therefore criticized as dangerously naive for ignoring this inherent moral hazard and the historical evidence of its consequences.

The Cult of the Free Market: 

Promises, Pitfalls, and the Need for Regulation

Ardent capitalists advocate for minimal government interference in markets, believing that private investors, unburdened by political considerations, will allocate their money for maximum profit, thereby ensuring optimal economic growth for all. 

This "free-market doctrine" is a dominant variant of the capitalist creed.

However, Harari contends that this belief is "as naive as belief in Santa Claus". 

Markets alone offer no protection against fraud, theft, and violence. It is the role of political systems to ensure trust through legislation, police forces, courts, and prisons. Historical events like the Mississippi Bubble and the 2007 US housing bubble serve as stark reminders of how market failures can occur when proper regulation and oversight are absent, leading to loss of trust, dwindling credit, and economic depression. 

The discussion of credit ratings and the failures of the Mississippi Bubble and the US housing bubble underscore that economic trust is intimately linked to political stability and the rule of law. The success of the Netherlands was not merely economic; it was rooted in a reliable legal system and the protection of private rights. 

Conversely, the financial woes of the French monarchy, exacerbated by the Mississippi Bubble, directly contributed to the French Revolution. 

This demonstrates a clear cause-and-effect relationship: political instability and a lack of trust in governance directly impact economic viability, leading to financial crises that can, in turn, trigger social unrest and political upheaval. The psychological impacts of losing savings and the potential for radicalization due to economic crises further reinforce this connection, suggesting that economic disruptions are not merely financial events but have profound societal and political consequences, highlighting the necessity of political oversight over markets.

IV. The Great Decoupling: 

AI, Human Value, and the Future of Society

This crucial section delves into the profound implications of artificial intelligence, particularly the decoupling of intelligence and consciousness, and its potential to redefine human value, reshape the labor market, erode individualism, and transform decision-making processes.

Intelligence vs. Consciousness: 

Redefining Human Utility in the Algorithmic Age

Harari identifies three critical threats to liberalism in the 21st century: humans losing their economic and military usefulness, the system valuing humans collectively but not as unique individuals, and the emergence of a new elite of upgraded superhumans. 

Liberalism's historical success was intimately tied to the economic and military value of every human, particularly in industrial mass wars and production lines, where each individual's contribution mattered.

However, modern armies increasingly rely on cutting-edge technology, requiring only small numbers of highly trained soldiers and experts, with critical decisions delegated to algorithms. 

Cyber-wars, potentially lasting mere minutes, could cripple infrastructure and financial systems, rendering human reaction times irrelevant. Harari suggests that autonomous robots and drones might even adhere to ethical algorithms more consistently than human soldiers. In the economic sphere, the value of physical and even many cognitive skills is diminishing.

A central argument by Harari is the decoupling of intelligence from consciousness. 

While high intelligence historically went hand in hand with developed consciousness (e.g., for chess, driving, diagnosis), new non-conscious AIs can perform such tasks through superior pattern recognition far better than humans. 

He provocatively concludes that for armies and corporations, "intelligence is mandatory but consciousness is optional". 

The analogy of human taxi drivers going the way of horses illustrates how humans could be replaced in professions where consciousness is not a necessary component for the system's needs.

The Automation of Labor: 

From Manual Tasks to White-Collar Professions

The trend of automation is already evident, with robots and 3D printers replacing workers in manual manufacturing. 

Highly intelligent algorithms are poised to do the same for white-collar occupations. Bank clerks and travel agents, once considered secure, are becoming endangered species as smartphone apps and algorithms take over their tasks. 

The majority of financial trading today is already managed by computer algorithms that can process data in seconds and react much faster than humans, leading to phenomena like "Flash Crashes" where trillions of dollars can vanish and reappear within minutes.

Even professions requiring significant cognitive abilities are vulnerable. Lawyers, for instance, face algorithms that can find precedents, analyze contracts, and summarize documents faster and more comprehensively than humans. The potential for fMRI scanners to act as "infallible truth machines" could render many roles for lawyers, judges, police, and detectives obsolete. 

In education, companies like Mindojo are developing interactive algorithms that personalize learning, adapt to individual student personalities, and never lose patience.

Doctors, particularly general practitioners and specialists in narrow fields like cancer diagnosis, are also "fair game". IBM's Watson, an AI system, demonstrates enormous advantages over human doctors due to its ability to store vast medical databases, update daily, know patient histories and genomes accurately, and operate without fatigue or bias. Robotic pharmacists have already proven superior accuracy to human counterparts. Even customer service is being transformed, with companies like Mattersight Corporation using algorithms to route calls to representatives whose personalities best match the customer's mood, creating a "personality connection".

Even in the realm of artistic creation, often considered a uniquely human sanctuary, vulnerability is observed. David Cope's EMI (Experiments in Musical Intelligence) composed 5,000 Bach-style chorales in a single day, and his later program Annie, based on machine learning, explores music and haiku poetry, with human and machine outputs often indistinguishable to experts. Recent advancements show companies like Suno and Udio can generate fully composed music with lyrics and vocals from simple text prompts. Even management functions are not immune, as Uber manages millions of taxi drivers with a handful of humans, and Deep Knowledge Ventures appointed an algorithm named VITAL to its board to vote on investments.

The Rise of the "Useless Class": 

Economic Irrelevance and Its Societal Implications

Harari warns of the emergence 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 class will not merely be unemployed but "unemployable". A 2013 Oxford study by Carl Benedikt Frey and Michael A. Osborne estimated that 47% of US jobs are at high risk of being taken over by computer algorithms within the next twenty years. 

Examples of occupations with high automation probability include 

telemarketers (99%), 

insurance underwriters (99%), 

sports referees (98%), 

cashiers (97%), 

chefs (96%), 

waiters (94%), 

paralegal assistants (94%), 

tour guides (91%), 

bakers (89%), 

bus drivers (89%), 

construction laborers (88%), 

veterinary assistants (86%), 

security guards (84%), 

sailors (83%), 

bartenders (77%), 

archivists (76%), and carpenters (72%).

While new professions (e.g., virtual-world designers) are likely to emerge, Harari questions whether older workers displaced from traditional roles will be able to adapt to the rapid pace of technological progress. 

The core problem is not creating new jobs, but creating new jobs that humans can perform better than algorithms. This necessitates lifelong learning and continuous reinvention as the only way for humans to remain relevant in the job market, a challenge many may be unable to meet.

Harari suggests that technological abundance might make it feasible to sustain these "useless masses" without their effort, but the crucial challenge will be keeping them occupied and content. He grimly proposes "drugs and computer games" as potential solutions, which would, in turn, deal a "mortal blow to the liberal belief in the sacredness of human life and of human experiences". 

If algorithms displace human labor, wealth and power could concentrate in the hands of a tiny elite owning these powerful algorithms, leading to unprecedented social and political inequality. Harari even postulates that algorithms themselves could become "legal persons" and owners, potentially forming an "algorithmic upper class".

The prognosis of a large, unemployable "useless class" presents existential challenges beyond economic ones, impacting meaning, mental health, and social stability. Harari's warning about the need to keep the "useless class" "occupied and content" with distractions directly references psychological research on the effects of unemployment. 

The loss of work affects not only income but also identity, purpose, and social status. If Universal Basic Income (UBI) provides only minimal handouts , it might exacerbate these psychological issues rather than solve them, by reinforcing a sense of uselessness. 

This creates fertile ground for social anger and resentment, which can be exploited by radical ideologies , especially when coupled with economic hardship and perceived injustice. 

The political consequences of financial crises further suggest that this technological disruption could lead to significant societal fragmentation and political instability, potentially pushing societies towards authoritarianism or populism if the crisis of meaning is not addressed.

The Erosion of Individualism: 

Algorithms Knowing Us Better Than Ourselves

The rise of algorithms directly challenges the liberal belief in individualism, which rests on three core assumptions: 

(1) The individual possesses a single, indivisible essence and an "authentic self"; 

(2) this authentic self is completely free; and 

(3) only the individual has access to their inner space of freedom and can truly know themselves.

Harari argues, however, that life sciences fundamentally challenge these assumptions: 

(1) Organisms (including humans) are "dividuals"—an assemblage of many different algorithms lacking a single inner voice or self; 

(2) human algorithms are not free but are shaped by genes and environmental pressures, making decisions either deterministically or randomly; and 

(3) external algorithms could theoretically "know me much better than I can ever know myself" by monitoring the biochemical systems of the body and brain.

Twenty-first-century technology, Harari states, enables external algorithms to "hack humanity" and know individuals far better than they know themselves. 

Once this occurs, the belief in individualism will collapse, and authority will shift from individual humans to networked algorithms. People will become accustomed to seeing themselves as biochemical mechanisms constantly monitored and guided by electronic algorithms. 

This shift does not require a perfect algorithm, only one that knows you better and makes fewer mistakes than you do.

The decoupling of intelligence and consciousness, and the resulting rise of algorithms that know us better than we know ourselves, directly threaten the liberal ideal of individual autonomy and free will. 

This is not a violent overthrow but a voluntary surrender in favor of convenience and supposedly optimal outcomes. 

Harari's core argument is that liberalism is built on the premise of the unique, free, self-knowing individual. If algorithms demonstrate superior decision-making in areas from health (Angelina Jolie's mastectomy) to relationships (Google advising on partners) to political choices (Google voting), the rational choice will be to follow the algorithm. 

This creates a subtle but profound shift: humans become "integral parts of a huge global network" managed by external algorithms. 

The "Quantified Self" movement is a real-world manifestation of this, where self-knowledge is outsourced to data analysis. The implication is a future where the concept of individual agency, as understood in liberalism, becomes obsolete, not through coercion but through a utilitarian acceptance of algorithmic superiority, leading to a "post-liberal world" where human self-determination is significantly curtailed.

Privacy in the Algorithmic Age: 

The Voluntary Sacrifice for Convenience and Health

A significant implication of this shift is the willingness to sacrifice privacy for perceived benefits. Harari uses the example of Angelina Jolie's decision to undergo a double mastectomy, based on a genetic test indicating an 87% probability of developing breast cancer, despite experiencing no symptoms. Her decision was influenced by algorithmic data and numbers, not her personal feelings, demonstrating a trust in algorithmic insights over intuition.

This willingness extends to everyday life, where people might "willingly dismantle the barriers protecting our private spaces" to allow state bureaucracies and multinational corporations access to their "innermost recesses" for improved health. For instance, allowing Google to read emails and monitor search queries could alert health services to brewing epidemics much faster than traditional methods. Google Flu Trends (tracking search queries) and the more ambitious Google Baseline Study (aiming to create a "perfect health profile" from biometric data) are existing examples. 

The growing market for DNA testing, exemplified by companies like 23andMe, further illustrates this trend. By providing saliva samples, individuals allow companies to analyze their DNA and provide predictions about health risks and genetic predispositions. 

This data, combined with other biometric information from wearables (e.g., smart diapers, smart armbands, contact lenses checking glucose), could create an "all-knowing medical health service" that monitors every aspect of a person's life. The "Quantified Self" movement, which believes self-knowledge comes from analyzing biometric data, embodies this ideology.

Transformation of Decision-Making: 

From Human Intuition to Algorithmic Guidance

The core implication for decision-making is that algorithms will become so good at making choices for us that it would be "madness not to follow their advice". 

This extends to personal decisions: Harari envisions a future where Google advises on movies, holidays, college studies, job offers, and even romantic partners, based on extensive personal data, biometric history, and statistical databases, providing a probability of satisfaction. 

This would lead to humans no longer being autonomous entities directed by their "narrating self," but integral parts of a huge global network.

Even political decisions could become obsolete. Liberal habits like democratic elections could become obsolete because algorithms like Google could represent political opinions better than individuals, by storing all past data, analyzing biometric reactions to news, and compensating for temporary biases like illness. 

A Facebook study already showed its algorithm could judge human personalities and inclinations better than friends, parents, and spouses, based on "Likes," with implications for identifying swing voters and influencing elections. 

Harari notes that personal data, often provided for free for services, is "the most valuable resource most humans still have to offer".

Algorithms could evolve from "oracles" (providing advice) to "agents" (executing aims without supervision) and ultimately to "sovereigns" (manipulating desires and making decisions). Waze, a GPS app, serves as an example: initially an oracle, it could become an agent in a self-driving car, and then a sovereign by manipulating traffic flow for optimal system-wide results, even if it means withholding information from some drivers. Similarly, personal assistants like Microsoft's Cortana, Google Now, and Apple's Siri are moving in the same direction, gaining increasing authority, making decisions, and even interacting with each other on behalf of their "masters". 

This could lead to a future where "success in the job market or the marriage market may increasingly depend on the quality of your Cortana". Devices like Amazon's Kindle could monitor reading habits, heart rate, and blood pressure, knowing "how to turn you on and off". Ultimately, disconnection from this all-knowing network might mean death, as future humans incorporate biometric devices and nano-robots that need to be online 24/7 for updates and security. Harari attributes this profound trend not primarily to computer science but to biological insights, concluding that "organisms are algorithms," thereby dismantling the wall between organic and inorganic and shifting authority from individual humans to networked algorithms. He warns that this could lead to an Orwellian police state, but more likely, the individual will "disintegrate gently from within".

V. Navigating the Future: 

Challenges, Responses, and Ethical Imperatives

This central section examines potential societal responses to the challenges posed by AI and advanced capitalism, including policy proposals like Universal Basic Income, the psychological toll of economic disruptions, the looming threat of biological inequality, and the critical need for ethical AI governance.

Societal Responses to Automation: 

The Promise and Peril of Universal Basic Income (UBI)

As AI and automation increasingly displace human labor, Universal Basic Income (UBI) has emerged as a potential "new social contract" and safety net. UBI aims to address key challenges such as wage inequality, job insecurity, and widespread job loss by providing a guaranteed minimum income to all citizens, regardless of their employment status or other factors. 

The concept has a long history, with early versions dating back to ancient Athens and modern formulations from thinkers like Thomas Paine and Joseph Charlier.

Over the past four decades, more than 160 UBI tests or pilot projects have been conducted worldwide, with over 38 in Europe, North America, and Asia since 2015. 

These studies generally show positive effects on poverty alleviation, health, and education outcomes, although evidence regarding impacts on employment is less clear, with some recent studies suggesting positive effects on employment outcomes and individual well-being. 

However, a significant danger of UBI is that it "might only deepen this problem". Critics argue that UBI, by habituating people to minimal handouts, could increase dependency and reinforce the belief that individuals have nothing meaningful to contribute to society, exacerbating psychological issues and a crisis of meaning.

The Psychological and Social Landscape of Disruption: 

Mental Health, Meaning, and Potential Unrest

Long-term unemployment is strongly linked to depression, mental illness, and higher suicide rates. 

The displacement of labor by AI creates a profound "crisis of purpose" for individuals who feel unwanted and unneeded. Work is not merely a source of income but a key component of identity and social status; its loss can lead to feelings of inferiority, resentment, and aggression.

Financial stress resulting from job loss or economic uncertainty significantly impacts mental health, leading to anxiety, depression, substance abuse, and strained relationships. 

The subjective perception of financial distress is often more impactful than objective financial facts. Historically, periods of economic turmoil and hyperinflation (e.g., Weimar Republic) have been associated with political extremism and social unrest, although the direct causal link between hyperinflation and the rise of Nazism is debated.

Financial crises have also led to increased political polarization. Economic hardship can intensify cultural and political divides rather than solely economic ones. Radical parties often gain electoral support when citizens lose patience with mainstream political parties during prolonged crises. The increasing demands of welfare states for "other people's money" can lead to fiscal unsustainability and populism. 

Fiscal illusion (hidden taxes, public debt) encourages citizens to demand more "free" privileges, creating a moral hazard. Conflict between long-time inhabitants and immigrants in welfare states can lead to social anger and increased votes for far-right parties. State bankruptcy can lead to misgovernance and reliance on bailouts.

The Growing Chasm: 

Amplifying Inequality and the Rise of Superhumans

The third major threat to liberalism is the potential emergence of a small, privileged elite of "upgraded superhumans". These individuals would possess "unheard-of abilities and unprecedented creativity," enabling them to continue making crucial decisions in the world, while the majority of humans would become an "inferior caste" dominated by both algorithms and these new superhumans.

Liberalism, while tolerating socio-economic disparities, fundamentally presupposes that all humans have equal value and authority. 

This foundation, however, is threatened by the potential for real biological differences arising from expensive genetic tests and new medical procedures. 

Angelina Jolie's $3,000 genetic test for the BRCA1 mutation, contrasted with billions of people earning less than $1-2 per day, highlights existing economic inequality that could translate into biological stratification. The fact that the 62 richest people in 2016 held as much wealth as the poorest 3.6 billion people underscores this widening chasm.

Harari argues that the expectation that medical breakthroughs will ultimately benefit everyone (like vaccines and antibiotics in the 20th century) might be "wishful thinking" for two reasons:

Conceptual Revolution in Medicine: 

20th-century medicine aimed to "heal the sick" (an egalitarian project based on a universal health norm), while 21st-century medicine increasingly aims to "upgrade the healthy" (an elitist project designed to give some individuals an edge over others). These upgrades would become the new baseline, ensuring the elite always remains "a couple of steps ahead".

Loss of Elite Interest in Mass Healthcare: 

As human soldiers and workers become obsolete due to algorithms, elites might conclude there is "no point in providing improved or even standard levels of health for masses of useless poor people". Instead, it might be deemed more sensible to concentrate resources on "upgrading a handful of superhumans beyond the norm". 

Harari uses the analogy of a "long train," where elites in first-class carriages might "let go of the useless third-class carriages" to remain globally competitive. This biological divergence could lead to superhumans having fundamentally different experiences from normal Sapiens, potentially treating them no better than 19th-century Europeans treated Africans.

The shift from the egalitarian "healing the sick" to the elitist "upgrading the healthy" could create irreversible biological stratification, fundamentally challenging the liberal belief in the equal worth of all humans. The historical examples of capitalism's "dark side" demonstrate that unchecked economic drives can lead to immense human suffering. Current discussions on AI ethics are a direct response to the potential for similar or even greater harm in the algorithmic age. The risks of bias, data breaches, and accountability gaps in AI indicate that simply leaving AI development to "free markets" is insufficient. 

The emphasis on "human-centered development" and "mitigating bias" in AI ethics principles reflects the recognition that technology must be guided by human values, not solely by efficiency or profit. 

This implies a critical, urgent role for governments, international organizations, and civil society in shaping AI's future to prevent a repeat of a "capitalist hell" scenario on a new, technological scale, requiring global ethical consensus.

Ethical Governance of AI: 

Principles for Responsible Development and Deployment

The rapid advancement of AI necessitates robust ethical guidelines to mitigate risks and ensure responsible development. Principles from organizations like the US Intelligence Community emphasize: 

respecting human dignity, rights, and freedoms; 

transparency and accountability in methods and outcomes; 

objectivity and equity through bias mitigation; 

human-centered development that augments human judgment; 

and secure and resilient design.

The United Nations' principles for the ethical use of AI, grounded in ethics and human rights, include: 

doing no harm; 

defined purpose, necessity, and proportionality; safety and security; 

fairness and non-discrimination; 

sustainability; 

the right to privacy, data protection, and data governance; 

and human autonomy. 

Specific risks in legal AI, for instance, include inherent biases from training data (e.g., gender bias in hiring algorithms), threats to client confidentiality when using AI tools, and complex questions regarding ownership and copyright of AI-generated content. 

Legal professionals, for example, have an ethical duty of competence that now explicitly includes understanding AI's capabilities and limitations, requiring significant human oversight for AI-assisted decisions.

The Imperative of Adaptation: 

Lifelong Learning and Reinvention in a Dynamic World

The traditional life model, divided into a learning phase and a working phase, will become "utterly obsolete". 

To remain relevant in an increasingly automated world, humans must continuously engage in lifelong learning and "reinvent themselves repeatedly". Harari warns, however, that many, if not most, people may be unable to adapt to this relentless pace of change. Human specialization, which enabled complex societies, paradoxically also makes humans more vulnerable to algorithmic displacement. 

Hunter-gatherers were generalists, harder to automate; modern professionals are specialists, easier to replace. The efficiency gains from specialization that fueled capitalism now create a vulnerability to AI. 

AI excels at mastering narrow, specialized tasks (like chess, legal research, medical diagnosis) by processing vast datasets and recognizing patterns. 

Human generalist skills (like empathy, complex problem-solving in unstructured environments, creativity beyond mere pattern recognition) are harder for current AI to replicate. However, Harari also challenges the idea of art as a sanctuary , suggesting even this is vulnerable. The implication is a continuous, accelerating race for humans to find and define new "uniquely human" niches, which themselves may be temporary, leading to constant societal upheaval and a potential inability of large segments of the population to adapt.

VI. Conclusion: 

Navigating the Post-Liberal World

The history of money is a narrative of trust and human imagination, evolving from simple barter systems to complex digital networks. While money enabled unprecedented cooperation and propelled capitalism as a driver of immense growth, it reveals a profound duality. Capitalism, fueled by an ethic of greed and reinvestment, has generated immense wealth and fostered global connectivity but has also exhibited a dark side, marked by exploitation, slavery, and colonial atrocities, where the pursuit of profit overrode ethical considerations.

The advancing era of Artificial Intelligence presents humanity with an even more profound transformation. 

The decoupling of intelligence from consciousness threatens to redefine human value, creating a "useless class" of laborers displaced by algorithms. 

This constitutes not merely an economic but an existential crisis, raising questions of meaning, mental health, and social cohesion. 

Concurrently, the ability of algorithms to know humans better than they know themselves undermines the liberal notion of the autonomous individual, shifting decision-making authority increasingly to networked systems.

Furthermore, the potential to "upgrade the healthy" carries the risk of unprecedented biological inequality, fundamentally challenging liberal ideals of equal human worth and potentially fostering the emergence of a new superhuman caste. In the face of these challenges, proactive and ethical governance of AI is crucial to prevent the repetition of past patterns of exploitation and to ensure that technological advancements serve human well-being rather than undermining it. 

The future demands continuous human reinvention and a redefinition of the social contract to navigate the psychological and social consequences of this great decoupling, and to shape a future that transcends mere efficiency, preserving the intrinsic value of human life.
