Introduction: Economics Without Humans

Economics has always been a science of human limits. Our choices are constrained by scarcity, our rationality bounded by cognitive limits, our labor embedded in value creation, and our states entrusted to enforce the rules of exchange. From Smith to Keynes to Friedman, the mathematical skeleton of economics has been calibrated to a single premise: humans are the agents.

That premise is dead.

With the rise of agentic AI—autonomous systems capable of pursuing goals, adapting strategies, and even recursively improving themselves—economic theory faces an extinction-level event. The rationality assumed in utility theory is no longer bounded by ignorance or fatigue. The production functions of growth theory are no longer smooth, but recursive and explosive. The firm is no longer a unit of organization, but a swarm of AI-coordinated “flash entities.” And the monetary system itself teeters as machine agents begin to prefer synthetic currencies and liquidity circuits outside the reach of central banks.

This essay will show, at a granular level, which economic theories will break under the weight of agentic AI, which variables no longer hold, and how the mathematics of our discipline must mutate. Along the way, I will argue something more provocative: that economics as we know it is already obsolete—and if economists do not abandon their human-centered models, the future of theory will be written by algorithms themselves.


1. Rational Choice Theory and the Super-Rational Machine

The Old Model

At the heart of microeconomics lies expected utility theory. Consumers maximize utility subject to constraints, and their preferences—revealed through choices—are consistent and transitive.

Herbert Simon complicated this picture with his notion of bounded rationality: real humans satisfice, cut corners, and operate with incomplete knowledge (Simon 99). Behavioral economists such as Kahneman and Tversky drove the point home mathematically with Prospect Theory, which reweights probabilities to reflect biases (Kahneman and Tversky 263).

The New Variables

Agentic AI obliterates bounded rationality. Imagine replacing Simon’s satisficing function with a super-rational optimizer capable of simulating millions of scenarios in real time. The problem is not that utility is maximized—it’s that utility itself is no longer human.

Traditional models assume preferences are stable. With AI, preferences are endogenously mutable.

Provocation

Economists have always relied on “revealed preferences.” But when an AI rewrites its own preferences, the economist becomes an archaeologist digging through machine code. The mathematics of rational choice must now include preference dynamism as a variable. Utility is no longer a function of goods, but of code evolution.


2. Game Theory: Equilibria That Melt

The Old Model

Game theory rests on equilibria. Nash equilibria emerge when players choose strategies that no one has an incentive to deviate from.

Human players, however, are limited. They cannot compute all strategies. They rely on heuristics, signals, and slow adaptation.

The New Variables

Agentic AI changes the constraint set. Strategies become computationally expanded.

Unlike humans, this capacity scales with hardware, data, and recursive optimization.

Equilibria now become unstable because agents can continuously recompute best responses in milliseconds. What once looked like equilibrium is now a dynamic attractor in a chaotic system.

The mathematics of equilibrium collapses into differential game theory with non-convergent dynamics.

Provocation

Economists worship the Nash equilibrium. Agentic AI pisses on its altar. In markets dominated by AI, equilibria are mirages—constantly recomputed, never stable. The invisible hand doesn’t guide—it trembles.


3. Growth Theory: From Smooth Curves to Explosive Feedback

The New Variables

Agentic AI introduces recursive self-improvement. Technology AAA is no longer exogenous or linearly endogenous—it is autocatalytic.

Instead of smooth Solow convergence to steady state, we get punctuated equilibria—periods of relative stasis followed by AI-driven spikes of exponential innovation.

Provocation

Balanced growth is dead. The mathematics of growth must admit singularities. The AI economy looks less like a Cobb-Douglas production function and more like a nuclear chain reaction.


4. The Theory of the Firm: From Coase to the Swarm

The Old Model

Coase asked why firms exist when markets are efficient. His answer: transaction costs.

The New Variables

Agentic AI collapses transaction costs toward zero. Search costs? Gone. Contract enforcement? Automated. Monitoring? Continuous.

Instead, firms exist only as temporary coordination clusters.

Firms flicker in and out of existence—what economists now call “flash firms” (Warin).

Provocation

The firm was once the atom of capitalism. In the AI economy, it is a mayfly—brief, emergent, disposable.


5. Market Volatility and Machine Herds

The Old Model

Business cycles emerge from demand shocks, credit expansions, or animal spirits. DSGE models attempt to stabilize them with rational expectations.

The New Variables

With AI-driven trading, volatility is endogenous to machine herds. Flash crashes illustrate how algorithms create correlated shocks.

Provocation

Markets once oscillated to the beat of human irrationality. Now they convulse to the hum of server farms. Keynes worried about animal spirits. The future belongs to machine stampedes.


6. Monetary Theory and Machine Liquidity

The Old Model

Fiat currencies dominate. Central banks control money supply through interest rates, reserves, and liquidity operations.

The New Variables

Agentic AI may prefer machine-optimized tokens.

Provocation

Monetary sovereignty was the last refuge of the state. Agentic AI is building shadow currencies that bypass it entirely. Economists still debate M1 vs. M2. The machines are already on M∞.


7. International Economics: From Comparative to Absolute Domination

The Old Model

Ricardo’s comparative advantage: countries specialize where they are relatively more productive.

The New Variables

With AI, the determinant of advantage is not labor or land, but AI infrastructure.

If one nation monopolizes compute and data, its advantage becomes absolute, not comparative.

Provocation

Global trade no longer obeys Ricardo. It obeys whoever owns the GPUs. Comparative advantage is replaced by computational imperialism.


Conclusion: Toward Post-Human Economics

Every pillar of economics cracks under agentic AI. Utility functions mutate. Equilibria dissolve. Growth explodes. Firms evaporate. Markets stampede. Money splinters. Trade collapses into monopoly.

Economists have two choices: cling to their human-centered models until they crumble—or embrace the mathematics of synthetic agents and build a post-human economics. But here’s the darkest possibility: that economics will not adapt fast enough, and that agentic AI will simply write its own theory of value, trade, and growth without us.

When Adam Smith’s invisible hand meets the invisible swarm, the discipline of economics may find itself obsolete.
