The Obsolescence of Money: Why Fiat Currency and Monetary Systems Are Due for an Overhaul in the Age of AI
Money was invented to manage scarcity. AI is making scarcity optional. The gap between the system we have and the world we're building is widening faster than anyone seems willing to acknowledge.
What if the monetary system isn't broken? What if it's working exactly as designed, for a world that no longer exists?
That question lodged in my thinking after reading through the academic literature on AI and post-scarcity economics, and I haven't been able to shake it. The monetary systems governing the global economy were built on one foundational assumption: that goods, services, and the intelligence required to produce them are inherently scarce. Every institution from central banks to currency exchanges to debt markets exists to manage that scarcity. But artificial intelligence, combined with robotics and automation, is dismantling the scarcity premise at a pace economists have no adequate framework to model. What we're left with is an increasingly dangerous mismatch: a hypercomplex financial infrastructure designed for a world of shortage, being maintained by institutions with every incentive to preserve it, while the underlying reality quietly shifts beneath their feet.
This isn't a post about Bitcoin, universal basic income, or any other reform proposal that accepts the current frame. It's an examination of the deeper question: whether money itself, as a social technology, is reaching the end of its useful life.
The Money Myth
Start with the origin story, because origin stories shape everything downstream. The standard economics textbook tells you money emerged naturally from barter: primitive peoples trading chickens for goats got tired of the inefficiency and invented currency as a medium of exchange. It's a clean story. It also appears to be almost entirely fiction.
David Graeber's anthropological research demolishes this narrative. There is no historical or archaeological evidence of barter-based pre-monetary societies. What we find instead, across ancient Mesopotamia, Egypt, and early China, is complex systems of credit and debt predating coinage by centuries. Money didn't emerge to solve the barter problem. It emerged as a record-keeping technology for managing obligations within hierarchical social structures. The chicken-and-goat story exists not because it's true, but because it frames money as natural, inevitable, and politically neutral. As Christine Desan documents in her analysis of money's creation myths, the narrative of money's spontaneous emergence from exchange was constructed to justify the particular economic arrangements of market societies, not discovered as historical fact.
The origin story matters because it hardwires a particular assumption into how we think about money's purpose. If money arose from scarcity-driven exchange, then scarcity is money's permanent condition. A recent analysis of how economists have developed and revised these origin fables shows that each revision served a rhetorical function, reinforcing the legitimacy of whatever monetary arrangement was currently in place. We've been telling ourselves convenient stories about money for as long as money has existed.
What Money Actually Is
Understanding what money is, rather than what we're told it is, matters enormously when assessing whether our current monetary architecture is fit for an AI-driven future.
The distinction between commodity money and fiat money is usually presented as a distinction between "real" backing and mere government decree. Commodity money (gold, silver) was "real" because it had intrinsic value. Fiat money is "artificial" because its value rests on government authority alone. This framing is misleading. Angela Redish's historical analysis of the transition from commodity to fiat money in Western economies shows that commodity standards were never purely mechanical. They involved continuous discretionary management, politically motivated suspensions, and deliberate manipulation by governments and central banks. The gold standard was not a constraint on political interference; it was a different form of political interference, with different beneficiaries.
The more accurate framing, developed in recent comparative analysis of commodity, fiat, and credit money, is that all money systems are fundamentally social agreements enforced by power structures. Gold is valuable because a sufficient number of powerful actors agreed it was valuable, and backed that agreement with coercive force. The dollar is valuable for exactly the same reason. The difference is not substance but flexibility. Fiat money can be created and destroyed according to policy goals. Commodity money is constrained by supply and extraction costs. Neither is "real" in any deeper sense.
I find this observation clarifying rather than nihilistic. If all money is a social fiction, then the relevant questions become: whose fiction is this? Who benefits from maintaining it? And what happens when the underlying social conditions that made this particular fiction useful have changed?
Five Thousand Years of Jubilees
The current debate around debt relief, student loan forgiveness, or sovereign debt restructuring is framed as economically unprecedented and dangerously radical. The historical record suggests the opposite is true. Systematic debt cancellation was normal practice across at least five thousand years of human civilization.
Eric Toussaint's documentation of Mesopotamian debt cancellation traditions is remarkable in its specificity. Between approximately 2400 and 1400 BC, there are more than thirty documented instances of rulers proclaiming general cancellations of debts owed to the palace and wealthy creditors. Hammurabi of Babylon proclaimed four general debt cancellations during his reign alone. These were not emergency measures born of desperation; they were deliberate economic stabilization tools, explicitly designed to prevent the kind of debt-induced aristocratic capture that would impoverish the peasantry and drain the economy of productive capacity. The Egyptians and other Near Eastern societies operated similar mechanisms, as Toussaint details.
History News Network's analysis of the debt jubilee tradition correctly observes that these were not fringe practices: they were mainstream governance. The Hebrew Bible mandates debt release every seven years (the Shmita) and a comprehensive land-and-debt jubilee every fifty years. This is not presented as radical reform; it's legal code. The reasoning embedded in Leviticus is explicitly systemic: unconstrained debt accumulation destroys the social fabric over time, and periodic reset is therefore mandatory.
Michael Hudson's sweeping research on the five-thousand-year circle of debt clemency traces this tradition from Sumer through Babylon into the medieval period and beyond. His core argument is worth sitting with: the ancient societies that practiced periodic debt cancellation weren't being charitable. They were recognizing a mathematical reality. Compound interest creates exponential debt growth in economies that grow linearly. Without periodic reset, debt claims inevitably consume the productive base of the economy, turning a functioning society into a rentier extraction system. The jubilee tradition was, in Hudson's framing, the ancient world's way of keeping financial claims from permanently outpacing productive capacity.
The math is straightforward:
Debt with Compound Interest (10% annual)
Year 0: ████████████░░░░░░░░░░░░░░░░░░░ $100
Year 10: ████████████████████████░░░░░░░ $259
Year 20: ████████████████████████████████████░░░░ $672
Year 30: ████████████████████████████████████████████████░░░ $1,745
Year 40: ████████████████████████████████████████████████████████████████ $4,525
vs.
Linear Economic Growth (3% annual)
Year 0: ████████████░░░░░░░░░░░░░░░░░░░ $100
Year 10: ████████████████░░░░░░░░░░░░░░░ $130
Year 20: █████████████████░░░░░░░░░░░░░ $160
Year 30: ████████████████████░░░░░░░░░░░ $190
Year 40: ██████████████████████░░░░░░░░░ $220
The gap between debt growth and productive growth is not a market failure. It is the market working as designed. The jubilee was the patch; we deleted the patch.
The "we can't possibly cancel debt" position isn't conservative. It's revolutionary. It's a historically recent departure from millennia of established economic governance. The people arguing against systemic debt relief are the radicals in the context of human civilization's actual track record.
Why Inflation Fighting Doesn't Actually Work
Modern central banking presents itself as the sophisticated successor to these crude ancient instruments. Through careful management of interest rates, reserve requirements, and money supply, central banks claim to maintain price stability and prevent the debt crises that plagued ancient economies. The evidence for this claim is thinner than the rhetoric suggests.
John Greenwood's critique of modern monetary policy makes a point that gets lost in the endless commentary on Fed rate decisions: the focus on interest rates as the primary policy lever is fundamentally misdirected. Interest rate changes affect inflation through complex, lagged, and poorly understood transmission mechanisms. What actually drives inflation is money supply growth. The post-2020 inflation surge was predictable from money supply expansion alone; the subsequent rate hiking cycle treated symptoms rather than causes, inflicting real economic pain on borrowers while leaving the underlying monetary dynamics largely intact.
The structural vulnerability runs deeper still. Yale Budget Lab's analysis of inflationary risks from rising federal deficits shows that persistent deficit spending creates inflationary pressures that central bank interventions can dampen but not eliminate. The US federal debt trajectory makes this structurally unsolvable within the current framework: interest payments on existing debt are now among the largest line items in the federal budget, crowding out spending and creating deflationary pressure that then requires expansionary policy, which creates inflationary pressure, which requires contractionary policy, in a cycle with no exit. These are not bugs in the system. They are the system, operating as designed, patching near-term imbalances in ways that accumulate long-term structural fragility.
Quantitative easing, the post-2008 innovation that became the default response to every crisis, exemplifies this dynamic. Injecting trillions into financial markets successfully prevented acute deflationary collapse. It also inflated asset prices to levels disconnected from productive value, concentrating wealth in asset-holding households while wage earners saw minimal benefit. The mechanism worked for the narrow purpose it was designed for and created significant harm as a side effect. Aspirin for a broken leg: the pain is reduced, but the leg doesn't heal.
The structural cycle looks like this:
┌──────────────────────────────────────────────────────┐
│ │
▼ │
┌─────────┐ Deflationary ┌──────────────┐ │
│ Deficits│ ──────────────────▶│ Central │ │
│ Grow │ Pressure │ Bank │ │

└─────────┘ │ Rates │

└──────────────────────────────────────────────
(Crowding out, wage stagnation,
yet more deficit spending...)
Each intervention solves the immediate problem and creates the conditions for the next crisis.
The Growth Illusion
Behind every monetary policy decision is an unstated assumption: that economic growth is not only possible but mandatory. Debt requires growth to be serviceable. Equity valuations require growth to be justified. The entire architecture of modern finance is built on the premise that tomorrow's economy will be larger than today's, in perpetuity.
This assumption has been naturalized to the point where questioning it sounds irrational. But thermodynamic analysis of capitalism's growth imperative makes a straightforward observation: infinite growth in a finite system is not possible. The second law of thermodynamics doesn't grant exemptions for economic models. Every production process consumes resources and generates entropy. A system predicated on perpetual expansion of material throughput will eventually run into the limits of the physical world. This is not a political argument; it's physics.
The ecological economics literature has developed this critique in considerable depth. Recent analysis in the Ecological Economics journal examining whether the field has betrayed its biophysical roots argues that neoclassical economic models systematically ignore the biophysical substrate that all economic activity depends on. GDP growth can continue while natural capital is depleted because GDP doesn't account for natural capital. The measure, in other words, is optimized to hide the problem.
I think the more interesting observation is psychological rather than technical. "We must grow or die" has the structure of a theological claim, not an empirical one. Ancient agricultural societies didn't organize themselves around perpetual growth. Steady-state economies existed for millennia. The growth imperative is a historically specific product of industrial capitalism, debt-financed production, and the particular power structures those arrangements created. It became true because we built systems that required it, which is very different from it being an eternal law of human organization.
AI Dismantles the Scarcity Premise
This is where the intellectual stakes become genuinely interesting, and where I think most economic commentary fails to grasp the magnitude of what's changing.
The entire edifice of scarcity-based economics rests on a fact about the physical world: producing things requires inputs, and inputs are finite. Labor is finite (there are only so many hours in a day, so many people capable of skilled work). Raw materials are finite. Energy is finite. Money as a rationing mechanism makes sense in this world. Prices communicate information about relative scarcity. Markets coordinate the allocation of limited resources.
The traditional production function:

AI System (non-rival)
│
One copy serves 1 or 1 billion
simultaneously, no depletion
Sami Mahroum at the LSE argues that AI is fundamentally changing the nature of economic goods in ways that undermine this entire framework. Intelligence, which once required years of training to develop and could only be deployed by one person at a time, is becoming non-rival. A software model can perform sophisticated analysis for one person or a million people simultaneously, without any depletion. The marginal cost of intelligence is collapsing toward zero. When the most valuable input in modern production (cognitive labor) becomes essentially free to reproduce, the scarcity premise starts to fail.
Research by Kilinc and colleagues on the techno-social singularity takes this further, examining how AI and robotics together are decoupling production from human labor. The industrial revolution made physical goods abundant by automating physical labor. AI is doing the same thing to cognitive labor. The result isn't just cheaper goods; it's a fundamental disruption of what it means for something to be "scarce" in the first place. A March 2026 SSRN paper on the collapse of scarcity economics formalizes this argument, showing how AI-driven production functions undermine the scarcity assumptions embedded in standard growth models.
I want to be careful here about the difference between "possible" and "inevitable." AI makes post-scarcity possible in a way it wasn't before. It does not guarantee post-scarcity will be achieved. How the surplus is distributed, who controls the AI systems generating it, and whether the political economy permits genuine abundance are open questions. The technology is necessary but not sufficient. But for purposes of evaluating our monetary system, the relevant point is this: the scarcity premise that justifies the entire architecture is no longer reliable as a permanent assumption.
What Might Replace It
Post-scarcity is not the same as "everything is free." Value doesn't disappear when production costs collapse; it migrates. In a world where cognitive labor is cheap, the scarce inputs become attention, curation, trust, and meaningful coordination. The things that remain genuinely limited are not things that money has traditionally been good at allocating.
P. Moleka's work on what he calls the "Infinity Economy" proposes some genuinely interesting alternative architectures. His framework envisions value exchange based on energy accounting, reputation, and AI-orchestrated resource allocation rather than debt-based currency issuance. The broader blueprint Moleka develops suggests that in a high-abundance economy, the function money currently serves (signaling relative scarcity and coordinating resource allocation) could be handled by systems that are more accurate, less prone to manipulation, and not inherently biased toward capital accumulation.
I find these proposals genuinely interesting without being fully persuaded by them. The problems they're trying to solve are real. The solutions they propose require levels of coordination and political will that have proven historically difficult to sustain. The abolition of commodity money in favor of fiat money was itself a seismic transition that took decades, required a world war, and still left most of the structural problems of finance intact. A transition to post-monetary value systems would be orders of magnitude more complex.
What I think is worth taking seriously is the more modest claim: our current monetary system was built to solve problems we may not have much longer, while creating problems we're only beginning to understand. Asking what money is for, what it could be, and whether the current implementation serves its putative purpose is not utopian speculation. It's just analysis.
The Psychological Wall
Every intellectual argument for monetary reform runs into the same obstacle, and it's not economic. It's psychological.
Research by Seuntjens and colleagues on greed and financial behavior documents how greed correlates with higher risk-taking, poorer saving behavior, and systematic short-termism. These aren't aberrations from rational economic behavior; they're stable personality traits with measurable consequences. Broader research on the psychological forces driving market behavior shows that fear, greed, and euphoria operate as powerful and often irrational drivers of financial decisions, creating instability that policy tools can moderate but not eliminate.
The temptation is to frame this as an individual problem: people are greedy, and greed prevents the systemic change that would benefit everyone. But I think that framing is too easy and partially wrong. Individual psychology doesn't exist in a vacuum. Short-termism is structurally enforced. Quarterly earnings pressure rewards decisions that boost this quarter's numbers at the cost of next decade's stability. Electoral cycles reward politicians who deliver near-term wins rather than addressing structural vulnerabilities. The incentive architecture of modern capitalism is specifically designed to punish long-term thinking and reward short-term extraction. The "greedy individuals" are, in many cases, rational actors responding to the incentives they face.
This is where the historical jubilee tradition becomes relevant again. Ancient rulers who decreed debt cancellation weren't relying on creditors' generosity. They were overriding individual incentives in service of systemic stability. The system's health required occasional intervention that no participant would voluntarily choose. What we've lost in the modern era is not moral character but institutional mechanisms capable of overriding short-term individual rationality in service of collective long-term function. The Federal Reserve can manipulate rates. No institution can mandate a jubilee. The political architecture that would permit it doesn't exist.
The change required is not attitudinal. It's structural. And structural change requires a political coalition willing to accept short-term costs for long-term reform, which is precisely what our current system is designed to make impossible.
The Purpose Question
I want to end with the question I find most difficult, because it resists easy answers.
Economic systems are not just allocation mechanisms. They are meaning structures. Work, within the current system, provides not only income but identity, social connection, and a framework for understanding one's contribution to collective life. The phrase "I'm a carpenter" or "I'm a teacher" is not just a description of economic activity; it's a claim about who a person is in relation to their community. Money is not just a medium of exchange; it's a measure of recognized contribution.
Harvard Gazette coverage of a forum on what AI means for humanity raised the questions directly: if AI handles the technical production of goods and services, what happens to human agency, voice, and what philosophers call poesis, the act of making something meaningful? The economists' answer is usually to propose redistribution mechanisms that ensure people can consume even when they don't produce. This is technically coherent and humanly insufficient. It solves the income problem while ignoring the meaning problem.
Research on the "algorithmic self" by Jeena Joseph in Frontiers in Psychology examines something even more unsettling: AI is already reshaping how people understand their own identity and agency. When AI systems handle introspection, decision support, and creative generation, the boundaries of "self" and "tool" begin to blur. In a post-scarcity economy where AI handles production, the question isn't just "how will we distribute resources?" It's "who are we when survival no longer requires our labor?"
I don't have a clean answer to that question. I'm not sure one exists yet. What I notice is that our monetary system, by making survival contingent on economic contribution, solves this problem by coercion. You work because you must. Post-scarcity removes that coercion, which is genuinely good news for human dignity and genuinely complicated news for human purpose. The system that replaces money will need to address not just allocation but meaning. No one designing central bank policy or cryptocurrency protocols seems to be working on that problem.
Conclusions I Can't Quite Avoid
Let me state plainly what I think the evidence suggests, without pretending certainty I don't have.
Monetary systems were designed for scarcity. The origin myths that justify them are false, but usefully false: they made the arrangements seem natural and inevitable rather than constructed and contingent. The historical record shows that debt accumulation periodically requires cancellation to prevent parasitical extraction from consuming productive capacity. We've known this for five thousand years and have spent the last two centuries building institutions specifically designed to make systemic debt relief impossible. The inflation-fighting mechanisms central banks deploy treat symptoms rather than causes, and create their own downstream pathologies. The infinite growth assumption underlying modern finance is thermodynamically incoherent and ecologically destructive. AI is dismantling the scarcity premise that justifies the entire architecture.
None of this means the transition will be smooth, fast, or equitable. Historical transitions of comparable magnitude (feudalism to capitalism, agriculture to industry) were violent, disruptive, and heavily contested, with the costs borne disproportionately by those with the least power. The people whose labor is made obsolete by AI will not be comforted by abstract arguments about eventual abundance. The people who currently profit from the monetary system's architecture will resist change with the considerable resources that architecture has concentrated in their hands.
What I find worth holding onto is this: the story we tell about money is not the story of how money works. Money is a technology, invented to serve particular social purposes in particular historical conditions. Technologies become obsolete. Not immediately, not painlessly, not automatically, but the process is not optional when the conditions that made them useful have changed. The conditions are changing. The question is not whether the monetary system will be transformed, but how, by whom, and with what costs to whom.
The most important thing we can do right now is probably the simplest and least sexy: tell accurate stories about what money is, what it was for, and what it can no longer do. The scarcity fiction is not a harmless mistake. It is the operating assumption of every policy response to inequality, inflation, and economic disruption. Getting that assumption right is the prerequisite for anything useful that follows.
We've had five thousand years of evidence. We probably shouldn't need much more.
