First: The traits you were born with — intelligence, conscientiousness, height — follow a bell curve: symmetric, mean-reverting, self-correcting across generations. The wealth you were born into does not. It follows a power law. Per standard deviation, inherited wealth predicts lifetime income more strongly than cognitive ability. And unlike intelligence, wealth does not regress toward the mean when it passes to the next generation — it compounds.
Second: The historical wire connecting intelligence to income — IQ → credentials → high-paying knowledge work — is being cut by artificial intelligence. The IQ premium in the labour market is collapsing. The capital premium is not.
Third: The third is a prediction with a deadline. As assortative mating intensifies around wealth rather than credentials, the biological and legal inheritance channels fuse into the same families. Three or four generations of that produces aristocracy — not by decree, but by mathematics. But the transition is not yet complete. For the next five to ten years, domain expertise combined with AI fluency commands a premium that is not gated by inherited wealth. That window closes when the integration matures. After it closes, the legal clock runs alone. The model says the window is open now. Act accordingly.
You are running on two clocks simultaneously, and they have opposite mechanics.
The first clock is biological. It governs intelligence, personality, physical traits — everything transmitted through chromosomes. This clock regresses toward the mean. The child of two people with IQs of 135 will, on average, have an IQ closer to 115. Genes are shuffled at every conception. Extreme values are diluted. The biological clock is, over the long run, self-correcting.
The second clock is legal. It governs wealth — everything transmitted through property law, through wills and trusts and alumni networks and the step-up in basis at death. This clock compounds. A house valued at $2 million does not become worth $1 million when it is inherited — it appreciates. Capital earns returns. There is no meiosis for money.
These two clocks interact multiplicatively, not additively. And they interact across a wealth threshold. Below roughly $20,000 in net worth — where about a quarter of American households live — the compounding mechanism does not operate at all: income is consumed by subsistence, savings cannot activate, and the second clock simply stops. Above it, the clock runs independently of traits, accelerating with the size of the initial position. The floor is not merely hard to escape from. It is, mathematically, a different country.
For most of human history, the wire connecting intelligence to heritable wealth did not exist. Before the bourgeois revolutions of the late eighteenth century, a brilliant peasant had no mechanism to convert that endowment into capital. Wealth ran through blood and title. Traits recirculated within class. The two clocks ran independently.
The French Revolution and industrial capitalism built a bridge. For the first time at scale, cognitive ability could be converted into credentials, and credentials into heritable wealth. The biological and legal channels began to couple. The meritocracy was always imperfect — the bell curve and the power law were never fully joined — but the bridge existed. It changed who the locked-in class was.
Artificial intelligence is dismantling that bridge. Large language models already match median professional performance on the routine, high-volume tasks that constitute a significant fraction of professional billing hours in law, finance, medicine, and software. This is not a prediction. It is 2025. The junior lawyer billing for research a model does in seconds is not being made more productive. They are being made unnecessary. Andrej Karpathy’s AI job-exposure visualiser maps 342 occupations by how thoroughly AI reshapes them: software engineers, data analysts, and paralegals all score 8–9 out of 10. Roofers and plumbers anchor the low end. That is not a coincidence. It is the shape of Wave 1.
What this means for the income equation is specific. The current model gives wealth a larger coefficient than intelligence — per standard deviation, it predicts income more strongly. That IQ premium is a historical artefact reflecting a century of scarcity of cognitive work. That scarcity is ending. A plausible trajectory over the next fifteen years puts the IQ coefficient somewhere between 0.10 and 0.20. The wealth coefficient, meanwhile, rises — capital owns the AI, and the productivity gains from AI disproportionately accrue to the shareholders of the companies that own the models. The multiplication still holds. But now one factor dominates almost entirely.
The coming disruption does not flatten the bell curve. It severs the wire connecting the bell curve to the income distribution.
But the transition creates a window, and it is worth being specific about what that window is. AI tools now exist that can dramatically amplify the output of a domain expert — a nurse, a logistics manager, a structural engineer, a teacher, a lawyer, a radiologist — who understands both their domain deeply and what the tools can and cannot reliably do. That combination is currently scarce. It will not remain scarce: as workflows standardise and vendors commoditise the integration, the premium for being early will compress toward zero. The window is open now, probably for five to seven more years in most domains. The people who build at that intersection — who take a decade of domain knowledge and apply it to AI integration before the market has priced it — are capturing a transition premium that is not gated by inherited wealth. It is gated by speed, domain depth, and the willingness to act before the outcome is obvious. Those are things a person with cognitive ability and modest starting wealth can actually have. The simulation below shows what comes after the window closes: five generations of what regresses and what compounds. Set your own starting positions, then reduce the IQ→income β to 0.10 — the AI-economy scenario. Watch what trait advantage does to the wealth rows. The window is the gap between those two runs.
A second wave is already building in the background. Industrial robot density doubled in seven years according to the IFR; Amazon runs over a million robots in its fulfilment centres; $6 billion flowed into robotics startups in the first seven months of 2025 alone. The physical jobs that AI cannot yet replace — construction, care, logistics — are already being automated at industrial scale in spaces most people never see. When that automation crosses into visible everyday domains, the adjustment will feel sudden rather than gradual. But the deeper point is economic: physical jobs were never the low-capital path to heritable wealth. They were the survival floor — income sufficient to live on, but structurally insufficient to clear the $20k wealth threshold and enter the compounding tier. Knowledge work was the only bridge between cognitive ability and that tier. AI is pulling that bridge up. Robotics will then remove the floor. The two waves together extend the consolidation window from one decade to two or three — and make the arithmetic deadline for the first wave more, not less, urgent.
This framework makes a prediction specific enough to be falsifiable. Within the next decade: the income share captured by capital will rise to levels not seen since before the New Deal. Assortative mating will shift from sorting on credentials toward sorting on net worth directly, as the credential screen loses its signal value. Watch the Bureau of Labor Statistics wage data against S&P 500 earnings-per-share growth. Watch the labour share of GDP. These numbers are published quarterly. The model says they will diverge. The current trajectory suggests they already are. And if they diverge as predicted — if the wire severs on the timeline the model implies — then the window described above is not a metaphor. It is an arithmetic deadline.
The biological clock self-corrects. The legal clock does not. Wave 1 — AI dismantling knowledge work — severs the wire that let the biological clock feed the legal one. Wave 2 — robotics removing the physical-work floor — is building behind it. The combined effect, playing out across two to three decades, leaves capital ownership as the only durable source of income that does not erode. The window before the first wave closes is roughly the next decade. The legal mechanisms maintaining the compounding tier are specific and changeable: the step-up in cost basis at death, dynasty trust laws in sixteen US states, and an estate tax threshold of $13.6 million below which the entire mechanism operates untouched — all words in documents, rewritable by human decision. The model makes this specific. The simulations make it visible. The full essay makes it actionable.
Two waves. The first is already cresting. The second is building. The full essay builds the complete case across eight sections — with all six interactive simulations, the assortative mating dynamics, the legal architecture that keeps the compounding clock running, and a closing letter to my children about what to do with the window while it is open.
