The Metrics of Immortality
Let me ask you to construct a realistic, but remarkably positive, scenario.
In this future timeline, biogerontological life-extension technologies emerge quickly. By that I mean something fairly mundane at first: medical treatments that are expensive, achieve only modest results, are available in only a handful of countries, attract suspicion, are used mainly by wealthy or unusually motivated early adopters, and have numerous failure modes.
For the purposes of this discussion, I am deliberately combining several related fields into one technological trajectory: slowing biological aging, extending healthspan, repairing accumulated age-related damage, and eventually reversing significant aspects of aging.
I want to concentrate primarily on biological interventions, because the underlying thesis is universality. These treatments eventually achieve mass penetration. That becomes considerably more difficult if, during the early stages, effective treatment requires elaborate ex-vivo RNA procedures, major surgery, extensive cybernetic implantation, repeated organ replacement, or similarly infrastructure-heavy interventions.
Such technologies may still become part of the mature system later. But for this scenario, I want the industry to bootstrap itself first through treatments that can plausibly diffuse through ordinary medicine.
Let us use 2030 as the starting benchmark, and examine development in increments of 2.5 years.
The important metrics are not simply whether the science improves. They concern the entire social and technological ecology surrounding treatment.
- How expensive are the treatments?
- How severely are they rationed?
- How technically complicated are they to administer, and how much specialist expertise or infrastructure do they require?
- How much political, regulatory, institutional, religious, and cultural resistance do they encounter?
- How narrow are their effects? Early treatments may improve one or several aspects of aging while leaving most of the underlying process untouched.
- Where do they first become available? It seems entirely plausible that some early interventions appear first in countries regarded by Western regulators as medically, politically, or ethically “problematic.”
- How hostile is the public reaction? Early life-extension medicine is likely to attract conspiracy theories, moral panic, distrust, and substantial levels of voluntary refusal or “defection.”
- How convincing is the science? Early interventions may suffer from verification problems, uncertain biomarkers, conflicting studies, long validation periods, difficulty demonstrating actual lifespan effects, and chronic problems securing implementation funding.
- And finally, what is the patient experience? Early interventions are likely to be inconvenient, lengthy, uncomfortable, and primarily concerned with mitigating aging rather than reversing it.
Now impose a relatively optimistic constraint on the scenario.
Assume that over approximately fifty years, from 2030 to 2080, these technologies evolve from producing very limited and inconsistent effects to becoming close to universal.
That is very fast. Yet people inside the longevity field occasionally speak about the possibilities with an optimism that seems difficult to reconcile with the cautious public discussion. Aubrey de Grey has on several occasions responded privately to questions of timing with variations on, “you might be surprised.” David Sinclair’s presentations in the UAE can sound almost breathless by comparison with the conservatism of mainstream biomedical institutions.
So let us assume the optimistic trajectory actually happens.
- By the mature phase of the technology, the cost of treating biological aging has fallen far enough that even middle-income and semi-developing countries increasingly find treatment economically preferable to carrying the medical and social costs of large frail elderly populations.
- Treatments have become widely available through market competition and industrial scaling.
- Receiving treatment has become routine, perhaps no more culturally remarkable than vaccination, dentistry, or periodic medical screening.
- Institutions that were initially hostile or cautious have become welcoming and ideologically comfortable with intervention against biological aging.
- The therapies no longer merely reduce particular diseases associated with aging. They repair or reverse most of the underlying biological deterioration itself.
- Treatment is available almost everywhere.
- In many societies, refusing treatment has become socially unusual and may even carry a stigma comparable to refusing basic preventative medicine.
- Most importantly, the technological paradigm has shifted from mitigating aging to reversing aging.
For a concrete case study, let us use the Netherlands.
There are some obvious reasons for doing so. Amsterdam hosts the European Medicines Agency. The Netherlands possesses a dense life-sciences ecosystem, and Leiden Bio Science Park ranks among Europe’s major biotechnology clusters. At the same time, the country’s own biotechnology sector acknowledges important weaknesses. The Netherlands is less successful than Switzerland, Ireland, or Belgium at attracting major global headquarters, and its competitive advantage lies more in agility, connectivity, scientific density, and institutional coordination than sheer industrial scale.
There is also an active government effort to change that position, including roughly €1.3 billion in additional National Growth Fund investment and an explicit ambition to make the Netherlands a major biotechnology economy. But that is essentially a bet on where the country wants to be around 2040, rather than evidence that it already occupies that position today.
Now add the demographic dimension.
At present, roughly fifty million or more human deaths each year can reasonably be described as age-related in the broad sense. People become biologically frail through aging, and eventually die from diseases and failures that this accumulated frailty makes possible.
In our scenario, beginning around 2030, that enormous annual death toll starts to decline.
At first the change is almost immeasurable.
For years, improvements in treatment are too small, too expensive, too unevenly distributed, and too geographically restricted to make a dramatic difference to global mortality statistics.
But over successive decades the curve begins to bend.
Even by 2080, however, a substantial number of people would presumably still die from age-related causes. Universal technology does not imply universal adoption, perfect distribution, or perfect efficacy.
Large populations may still live in countries that cannot afford the treatments. Some health systems may be too dysfunctional to deliver them reliably. Some populations may distrust them or lack access to the education required to evaluate competing claims. Logistics may fail. Markets may be inefficient. Governments may ration treatment deliberately.
Local institutions may discriminate. Welfare recipients, prisoners, migrants, ethnic minorities, politically disfavoured groups, or geographically isolated populations may encounter artificial bottlenecks.
Some treatments will almost certainly be fraudulent or exaggerated. Others may work but produce side effects that become apparent only after years or decades of use. Particular interventions may introduce unexpected trade-offs, perhaps even affecting fertility or other biological systems.
Certain religions, political movements, economic systems, or cultures may remain deeply hostile to life-extension medicine long after it has become normal elsewhere. Some could maintain high rates of voluntary refusal well beyond 2100. Over sufficiently long periods, that resistance could itself create a peculiar form of demographic self-selection.
Some countries may remain isolated by sanctions or geopolitical barriers. Others may simply lack the institutional capacity required to participate.
So the interesting question is not merely when does aging become treatable?
The more useful question is:
What does the fifty-year transition from rare, expensive, controversial, technically awkward aging mitigation in 2030 to cheap, routine, globally distributed biological age reversal around 2080 actually look like, when measured across cost, complexity, access, institutional acceptance, public adoption, scientific confidence, treatment burden, and global mortality?
REPLY ONE
Your question forces me to jump through a most interesting hoop. There is, in fact, a significant minority within the anti-aging field who believe that something resembling these numbers is possible, although I agree that some of their public and private statements can sound decidedly breathless. I shall refrain from adding further criticism, because doing so does not particularly serve the thought experiment. Suffice it to say that I do not think the premise is entirely ludicrous.
You have also chosen the Netherlands deliberately as a place where the transition might proceed unusually well.
That is useful, because the Netherlands contains several characteristics that would reinforce one another. It has a stable economy, a sophisticated medical system, high institutional capacity, a scientifically literate population, extensive social insurance, and an existing political expectation that the state should spend substantial resources preventing citizens from falling into extreme ill health or destitution.
More importantly, it has something less romantic and probably more powerful: an expensive aging population.
This matters enormously.
The first serious political argument for biogerontological medicine might not be immortality at all.
It might be cost containment.
Suppose an early generation of treatments does nothing spectacular to maximum lifespan but reliably delays frailty, cardiovascular deterioration, metabolic disease, osteoporosis, immune decline, cognitive deterioration, and the cascade of interacting pathologies that make old age so medically expensive.
That is already economically transformative.
A government does not need to believe in radical life extension to become interested. It merely needs actuaries.
If spending €20,000, €30,000 or even considerably more on periodic interventions prevents €100,000 or €200,000 in later hospitalisation, residential care, disability support and medical management, the treatment begins to move out of the conceptual category of “longevity medicine” and into the much more politically comfortable category of preventative healthcare.
And once that happens, the rhetorical terrain changes very quickly.
The question ceases to be:
“Should society pay to make rich people live longer?”
It becomes:
“Why are we allowing citizens to become unnecessarily sick when preventing that sickness is cheaper?”
That is a completely different political proposition.
The Netherlands would be especially interesting because its social model creates unusually visible fiscal feedback loops. The government, health insurers, pension institutions, municipalities and employers all pay different portions of the enormous downstream cost of biological deterioration.
Initially those interests would not necessarily align. One institution might pay for the treatment while another receives the savings. There would be years of bureaucratic warfare over precisely this point.
But eventually somebody starts adding the columns together.
And that may be the moment at which biogerontology stops being an exotic biomedical sector and becomes a matter of national economic policy.
The next stage is stranger.
Once healthspan extension becomes substantial rather than marginal, the pension system itself begins to look increasingly peculiar.
Pension systems were designed around a fairly simple biological curve. People spend several decades becoming economically productive, work for a number of decades, become progressively less capable, retire, consume increasing amounts of healthcare and eventually die.
Biological rejuvenation attacks that curve.
If a seventy-year-old has the cardiovascular health, muscular strength, immune competence and cognitive resilience previously associated with someone decades younger, then chronological age becomes a very poor administrative proxy for capability.
At that point the concept of a statutory retirement age becomes increasingly difficult to defend in its present form.
And this becomes particularly interesting if the same period produces extensive automation and some form of universal basic income or guaranteed income floor.
Under such a system the traditional pension might gradually cease to function as the primary mechanism preventing destitution in old age. Instead, it could become an additional payment layered on top of a universal income system, perhaps reflecting accumulated contributions, previous employment, disability or other factors.
Now introduce effective rejuvenation.
The state acquires a very strong incentive to subsidise it.
Keep someone out of frailty and you save a fortune.
Keep someone biologically robust and that person may remain capable of education, entrepreneurship, care work, voluntary activity, artistic production, part-time employment or conventional paid labour for far longer.
Even modest labour participation matters.
A society does not require rejuvenated citizens to work forty-hour weeks until the heat death of the universe. If tens of millions of healthy people remain economically active for even a fraction of their additional healthy years, the fiscal consequences are enormous.
This creates a rather peculiar feedback mechanism.
The more expensive aging becomes, the stronger the incentive to treat aging.
The more effective treatment becomes, the less expensive old age becomes.
The less biologically meaningful old age becomes, the harder it becomes to justify institutions based entirely upon chronological age.
And the more those institutions change, the stronger the economic incentive becomes to make rejuvenation universally available.
At some point the entire system flips.
During the first stage, people demand access to rejuvenation and institutions resist paying for it.
During the mature stage, institutions may actively encourage people to receive rejuvenation because refusal imposes predictable costs upon the collective system.
That is where your apparently extravagant claim that refusing treatment eventually becomes socially taboo starts becoming much more interesting.
Because the taboo would not necessarily arise from some cult of eternal youth.
It might emerge from exactly the same mundane social mechanisms that already surround vaccination, smoking, preventative medicine, education and retirement planning.
Imagine that by 2070 a course of rejuvenation costs the Dutch healthcare system €4,000 every several years and reliably prevents a large proportion of the medical conditions presently associated with advanced age.
Someone who refuses the treatment may then be perceived rather differently from someone refusing an experimental anti-aging therapy in 2035.
They are no longer refusing an exotic intervention.
They are voluntarily accepting a large probability of becoming medically dependent upon everyone else.
Insurers notice.
Governments notice.
Families notice.
Employers notice.
Eventually culture notices.
And this introduces an uncomfortable but probably unavoidable political question.
At what point does the right to age become analogous to the right to engage in other forms of medically expensive behaviour?
The answer will differ enormously between societies.
The Dutch model might remain comparatively permissive. Treatment could be strongly encouraged, automatically offered, extensively subsidised and integrated into ordinary healthcare while remaining formally voluntary.
Other countries might go considerably further.
Insurance premiums could change.
Eligibility for particular forms of disability support might change.
Employment law could change.
Retirement law could change.
Courts might eventually have to decide whether biological age rather than chronological age should determine certain rights or obligations.
Entire legal categories could become unstable.
And underneath all of this something philosophically much larger has happened.
For most of human civilisation, aging has been treated as an external constraint.
Governments could redistribute its consequences, religions could interpret it, physicians could alleviate it and families could care for its victims, but nobody could meaningfully negotiate with the underlying process.
Once aging becomes technologically alterable, it ceases to be merely a condition of human existence and becomes partially a matter of policy.
That changes everything.
A seventy-five-year-old suffering from frailty in 2025 is experiencing something society largely regards as unfortunate but natural.
A seventy-five-year-old suffering equivalent frailty in 2080, in a society where routine treatment could have prevented it, occupies a completely different moral and political category.
Someone made a decision.
Perhaps the patient refused treatment.
Perhaps an insurer refused reimbursement.
Perhaps a government failed to procure it.
Perhaps a physician failed to recommend it.
Perhaps a religious community discouraged it.
Perhaps poverty prevented access.
Perhaps sanctions prevented importation.
But aging is no longer simply something that happened.
It has acquired an attributable cause.
And once that occurs, the politics of aging become considerably more explosive than the politics of longevity ever were.
OVERPOPULATION
Now let me ask the inevitable overpopulation question, and I must confess that I regard much of the instinctive reaction to this as stupidity in action. People hear “radical life extension” and immediately perform a remarkably crude piece of arithmetic:
People stop dying + babies continue being born = population explosion.
But under the scenario we have just constructed, that is not remotely what happens. We currently have something on the order of fifty million deaths per year that can, in the broad sense relevant to this thought experiment, be associated with aging: people accumulate biological damage, become progressively frail, and eventually die from diseases and failures that this deterioration makes possible. But our hypothetical rejuvenation industry does not suddenly switch those deaths off in 2030.
Quite the opposite.
In 2030 we have a trickle of expensive, clumsy, partial interventions that mitigate particular components of aging. Their penetration is tiny. Their effectiveness is limited. Many people cannot afford them, cannot obtain them, distrust them, refuse them, receive them too late, or live under medical systems incapable of delivering them properly.
Then we spend fifty years slowly scaling the technology. So even if we grant our extraordinarily optimistic premise that something approaching mature, inexpensive, widely distributed rejuvenation exists around 2080, how many of those annual age-related deaths have actually disappeared by then? We are going to have to manufacture a number for the purposes of the model, because the technology itself is hypothetical. So let us manufacture one.
Suppose that by the end of the century we have prevented roughly forty million of those annual age-related deaths, while something like ten million people per year are still dying from aging and its consequences. That is an astonishing medical achievement. It is also very different from “nobody dies anymore.”
Moreover, those forty million avoided deaths do not appear overnight. They accumulate gradually across decades as treatments improve, prices fall, infrastructure expands, institutions adopt them and populations become willing to use them.
So what does this actually do to world population?
This becomes extraordinarily difficult to project, because an almost comical amount of chaotic stuff is going to happen during the same period.
For the purposes of this exercise, therefore, I want to impose an almost absurd degree of in vitro thinking.
Let us temporarily ignore climate change. …… Ignore wars, pandemics, migration shocks, political instability, economic inequality, capitalism, consumerism, artificial intelligence, social networks, the loneliness epidemic, gig culture, collapsing insect populations, feminism, the MeToo movement, abortion restrictions, changing sexual behaviour, antidepressant use, pornography, microplastics and whatever other demographic asteroid happens to wander into the laboratory over the next seventy years.
Some of those things may prove enormously consequential. No – I am certain most of them will be categorically future defining. But some others may turn out to have been temporary cultural weather. Others may interact in ways nobody currently anticipates. And entirely new phenomena could emerge that make today’s demographic anxieties look quaint.
One can easily imagine having this conversation in 2038:
“Khannea, this might be difficult to believe, but the loneliness epidemic turned out not to be terribly important. Global fertility is exploding because of the Cthulhu Hentaicle Gen Alpha movement. You’ll love it. VERY inclusive.”
“W… what??!!”
Precisely!
Long-range demographic prediction has a nasty habit of quietly assuming that future human beings will continue behaving approximately like present human beings while everything surrounding them changes beyond recognition. So strip all of that away. Freeze as many external variables as we reasonably can.
Take existing demographic tendencies as our baseline, then introduce only one major disturbance: a gradual decline in age-related mortality beginning around 2030, accelerating over fifty years, and eventually preventing perhaps forty million deaths annually while still leaving roughly ten million annual deaths from biological aging around the end of the century.
Under those deliberately artificial assumptions, what actually happens to global population between 2030 and 2100?
Does rejuvenation genuinely produce the catastrophic population explosion people reflexively imagine?
Or does it instead create something much slower and stranger: an aging demographic system gradually accumulating surviving adults while fertility, family formation, migration, economic incentives and eventually reproduction itself adjust around the new reality?
In other words:
What does the arithmetic of “overpopulation caused by immortality” actually look like once we stop pretending that fifty million people suddenly cease dying on January 1st, 2030?
Then what other major factors come into play? Billionaires? Inheritance? Oligarchs and Tyrants?
My theory has always been – old people have old neurology. young bodies have a young neurology and more agile myelinizaton, if that’s a thing? So my naive assumption is that by 2080 or so, we are cultivating a sub strata in the human population that is remarkably wise, has a politically increasingly long term view, is very aware of long term consequences, does not under any circumstances like to end up in prison, pay their taxes, can be understood to very concerned what the world might look like in 2200, might not be all that gung ho to hop on a rocket and go colonize the moon in claustrophobic tunnels and radiation and far away from rejuvenation clinics, right?
My assumption is actually – IF you are an oligarchs, sure. You wanna live forever. But if you already have the expectation to live long, last thing you want is to become a public spectacle. You want to reinvest in blue-sky thinking, long tail projects, idealism. No coal open air pit mines for you hombre. Not even leveraging costs to other countries, because repair payments and consequences and tribunals and accountability might very well catch up a few decades down the road and as we can see Gen Z is a generation that is growing up almost pathologically aware of consequences. Most boring generation ever.
How does this analysis sound? If you agree, enhance, where not push back.
Your analysis has a strong underlying logic, but I would sharpen the causal chain in one important way.
The strongest claim is not that rejuvenated people necessarily become wiser. It is that once people reasonably expect to remain alive for centuries, the consequences of their actions cease to belong primarily to descendants, institutions or some abstract posterity. They increasingly belong to the same person who made the original decision. That changes the effective discount rate on consequences. A fifty-five-year-old industrialist in the old world can externalize the costs of a poisoned aquifer, strip an asset, cash the dividend and assume that most of the consequences will belong to another generation. In a mature rejuvenation society, that same person may reasonably expect to be alive when the remediation bill arrives eighty years later. Her grandchildren are not inheriting the mess. She is. That is a very different incentive structure, and I think it is one of the strongest philosophical consequences of your whole scenario.
Where I would push back is on the neurological argument, at least in its simplest form. It is perfectly reasonable to suppose that whole-body rejuvenation would eventually include the brain, because a treatment regime that restored muscular, cardiovascular and immune function while leaving the brain progressively degraded would hardly count as comprehensive age reversal. There are plausible reasons to think that restored vascular health, lower neuroinflammation, better myelin maintenance, improved metabolic function and renewed plasticity could preserve or recover forms of cognitive agility. But even if that works spectacularly well, it does not follow that an older person becomes psychologically young. What emerges is something more interesting: a neurologically vigorous person carrying a century or more of accumulated memory, expertise, social pattern recognition and autobiographical history. That is not a young person. It is a type of human being that has barely existed before.
Such people could indeed become more strategically patient, more attentive to long-term consequences and more suspicious of reckless decisions whose costs arrive decades later. But they could also become extraordinarily persistent cranks, ideologues, fanatics or monopolists. A rejuvenated nervous system does not automatically improve a person’s values. It may simply give those values another century in which to operate. This is why I would separate long-horizon thinking from benevolence. The benevolent oligarch says, “I expect to be alive in 2170, so I had better preserve the biosphere, fund basic research and avoid leaving poisoned landscapes behind me.” The unpleasant oligarch says, “I expect to be alive in 2170, so I can finally execute a one-hundred-year monopoly strategy.” Both have solved the same temporal problem. The difference lies in what they want.
That makes billionaires, inheritance and political incumbency enormously important in this scenario. Mortality is one of the great involuntary redistributors of power. It is ugly, indiscriminate and often unjust, but it does force turnover. The tycoon dies, the dictator dies, the professor retires, the founder eventually disappears, the estate is divided, the heirs fight, the company changes hands and the institution acquires new leadership. Remove biological aging as a reliable source of turnover and you can create individuals with one hundred and fifty years of accumulated capital, professional knowledge, relationships, political influence and institutional memory. Someone who becomes extremely wealthy in 2050 and remains vigorous in 2190 could possess a degree of continuity that no historical aristocrat ever enjoyed. They could personally know six generations of politicians, remember every regulatory battle, every merger, every family alliance and every loophole their organization ever exploited.
For that reason, I suspect successful rejuvenation would make institutions such as term limits, anti-monopoly law, wealth taxation, land taxation and restrictions on permanent control more important rather than less important. Lifetime appointments become faintly absurd once a lifetime can encompass several political eras. A constitutional judge appointed in 2072 could still be sitting there in 2190 unless the legal system had anticipated the problem. The same applies to executive control, foundations, trusts and family companies. Institutions designed around the assumption that biology eventually removes incumbents would have to be rewritten because biology would no longer be doing that administrative housekeeping for us.
Inheritance becomes equally strange because inheritance itself starts to lose its traditional role. If your mother is one hundred and forty-three and you are one hundred and eleven, waiting for the family house begins to look ridiculous. Capital transfer would probably move away from death-triggered inheritance and toward gifts, family investment structures, rotating custodianship, age-independent taxation and legal devices that do not yet have familiar names. One of the most important metrics in such a society may therefore be capital turnover rather than inheritance in the narrow sense. Who controls assets, for how long, and under what conditions can society force extremely persistent concentrations of wealth and authority to circulate?
Your point about criminality and public spectacle is also stronger than it first appears. A radically extended future changes the value of reputation because reputation can follow you for an extraordinarily long time. Imagine committing a spectacular financial crime in 2068 and discovering that in 2140 much of the voting population still remembers the affair personally. The witnesses have not died. The journalists have not died. The people who protested outside your office may still be politically active. Historical memory stops being primarily archival and becomes biographical. That could create very strong incentives to avoid becoming a permanent public villain, particularly among people who already possess wealth, status and access to rejuvenation. The cost of being notorious is no longer a bad decade followed by retirement and death. It may be a bad century.
That would not necessarily create a more punitive society, however. The opposite problem appears immediately. If people can remain alive and socially active for centuries, it becomes absurd to define them permanently by an offense committed at forty. Criminal law would probably need much stronger mechanisms for rehabilitation, record expiration and social reset, precisely because a person may have another two hundred years of life ahead of them. A long-memory society therefore creates pressure in both directions. Reputation becomes more important, but the right to recover from a destroyed reputation may become more important as well.
Your environmental argument also works, but only if institutions become durable alongside individuals. A coal company executive who expects to be alive in eighty years has more reason to care about environmental liabilities, but only if there is some plausible mechanism by which those liabilities can actually return to her. If companies can dissolve themselves, states collapse, records vanish and jurisdictions refuse cooperation, then longevity merely teaches capital where to hide the cost. Long-lived individuals therefore create pressure for long-lived accountability. You would expect stronger archives, more durable liability rules, more international enforcement and perhaps much less tolerance for corporate structures designed solely to dump costs onto another jurisdiction or another century. Temporal externalization becomes harder, but geographical externalization remains possible, so the politics of rejuvenation would likely strengthen the argument for transnational institutions capable of making very old obligations stick.
This is also where I think your “no coal open-pit mines for you, hombre” intuition becomes more than a joke. A person who expects to be alive for the consequences of her own projects may become much more interested in long-tail investments, restoration, ecosystem management, resilient cities, research programs and infrastructure that takes half a century to mature. She may also become less attracted to projects whose profitability depends on being dead before the bill arrives. The shift is not necessarily moral enlightenment. It is simply that future costs become personal costs.
The same logic applies beautifully to space colonization. I do not think rejuvenated populations necessarily become less interested in space, but they may become much less interested in heroic, disposable colonization. Why volunteer to spend twenty years in a radiation-damaged tunnel beneath the Moon when Earth contains excellent food, social life, hospitals and the rejuvenation clinic that keeps you in peak condition? A society with a two-hundred-year planning horizon has much less reason to rush. It can send robots first, construct industrial infrastructure, solve shielding, develop closed ecosystems, establish medical facilities and build comfortable habitats before asking large numbers of people to move there. Long life could therefore make civilization less impatient about space while making it much more serious about actually building it properly.
That long planning horizon would affect far more than space. Forest restoration, flood control, scientific research, species recovery, language preservation, cathedral-scale architecture, terraforming, infrastructure and educational institutions all become easier to imagine when the people who initiate them expect to see the mature result themselves. One of the hidden pathologies of present civilization is that many important projects operate on timescales longer than the careers and lives of the people who begin them. Rejuvenation removes part of that discontinuity. A person can start a project at seventy and still be managing it at one hundred and forty, not because she created an immortal bureaucracy but because she is still there.
Political memory may be even more disruptive. Imagine a Dutch electorate in 2140 containing millions of people who personally remember debates from the 2040s. Politicians cannot as easily claim that nobody foresaw a disaster when large numbers of voters can reply that they attended the hearings where it was explicitly predicted. This could produce much stronger accountability and much less tolerance for historical revisionism. But again, there is a darker symmetry. Grudges also last. Ethnic conflict may become harder to extinguish when the people who experienced the original violence remain politically active a century later. Revolutionary generations do not disappear. Reactionary generations do not disappear. Generational replacement currently performs a large amount of invisible political garbage collection, and a rejuvenated civilization loses much of that mechanism.
I would therefore soften the Gen Z comparison. Younger generations today sometimes appear unusually preoccupied with consequences, systems, climate, social externalities and the ethical trace left by institutions, but that may have as much to do with information density and cultural conditions as age itself. Still, they offer a useful miniature of what happens when long-term consequences become culturally salient. In your rejuvenation society, that salience would become materially personal. People would not merely worry about what kind of world their grandchildren inherit. They would worry about what kind of world they themselves intend to inhabit in 2200.
The largest conceptual change, however, may be that chronological age stops functioning as a meaningful social category. Imagine walking into a room containing a thirty-two-year-old, a seventy-seven-year-old, a one-hundred-and-eighteen-year-old and a one-hundred-and-sixty-four-year-old, all of whom appear somewhere between thirty and forty, possess comparable physical capacity and have healthy brains. “The elderly” is no longer a coherent demographic bloc. The one-hundred-and-sixty-four-year-old may have been divorced five times, earned four degrees, changed professions eleven times, raised several temporally separated families and personally remembers society before artificial intelligence became ubiquitous. That person is not elderly in any conventional sense. She belongs to a new category.
What gradually emerges, then, is not a civilization of immortal young people but a deep population: biologically youthful or middle-aged human beings carrying extremely long personal histories. Some would become wise, some monstrous, some cautious, some adventurous, some magnificently dull. Some billionaires might fund hundred-year ecological restoration projects, while others might spend the same century attempting to own Belgium. Some people would devote eighty years to mastering the cello, others to municipal tax law, and some would maintain incomprehensible grudges against Luxembourg dating back to the 2090s. The important point is that the distant future becomes personal rather than ancestral.
That may ultimately be the deepest political consequence of the entire immortality scenario. For most of history, people could externalize consequences into a future inhabited largely by descendants and strangers. Under radical rejuvenation, a growing share of that future is inhabited by the same people who made the original decisions. The distant future stops being an abstraction. It becomes somewhere you expect to live.
I must make an interjection, you need not respond in great detail, but I think the mere symbol of Luigi Mangione might be one that casts a shadow forward in time for centuries. This man may have done something very important.
Let’s keep it at that.
Ok, given the above premises… describe me 2100. Game it out. And … I am 61 right now, a youthful filly of humble means living in de Jordaan in Amsterdam. Relatively healthy but with challenges. I am alive in 2100. I have a “youthful” body.
Walk me through the whole shenanigans.
2100
By 2100, you are chronologically about 135. Nobody says this with the solemnity we would attach to it now. It is a number in your medical record, your tax history, your passport metadata and probably the subject of occasional jokes. Biologically, however, you present as something much closer to a healthy woman in early middle adulthood. You move easily, recover quickly, retain muscle, skin elasticity, vascular competence, sensory acuity and a nervous system that has been repeatedly maintained rather than allowed to slide into accumulated deterioration. You do not feel like a preserved old person. That distinction matters enormously. The entire cultural victory of rejuvenation has been to make chronological age increasingly irrelevant to day-to-day embodiment.
You are still living in Amsterdam, perhaps even still in or near the Jordaan, although by then the neighborhood is effectively a historical organism wrapped inside twenty-first-century climate engineering, utility retrofits and layers of regulation nobody in 2026 would recognize. The façades survive because Amsterdam would sooner sell the Rijksmuseum than casually bulldoze the Jordaan, but behind them everything has changed. Buildings have been repeatedly insulated, flood-proofed, rewired, subdivided, recombined and adapted to generations of energy and climate standards. The city is quieter in some ways because a great deal of freight and service traffic has been automated, but denser in others because the Netherlands remains a magnet for people who want competent institutions, functioning medicine and a place in the European rejuvenation system. Property remains a political nightmare because one thing humanity did not cure was its capacity to turn square meters into theology.
Your economic position is where this scenario becomes more interesting, because rejuvenation does not arrive in a social vacuum. It arrives into lives that have already been shaped by class, disability, bureaucracy, luck, institutional judgment and the accumulated consequences of earlier decisions. In your own case, that history matters. By the mid-2000s you had already been through a period of severe instability, including conflict with municipal authorities, a divorce, repeated attempts to study and work, and a welfare regime that you experienced as punitive and suffocating. Some actions taken against you were, in your account, not merely harsh but demonstrably improper, while the possibility that individual political hostility played a role remains harder to prove and should probably be treated as suspicion rather than established fact. What is clearer is that the institutional environment you were in repeatedly narrowed your options at precisely the period in which your health made those options hardest to exercise.
The later decision by the UWV to recognize you as fully entitled to WAJONG therefore represented something much larger than a change of benefit category. It was a form of emancipation. The money was still modest, and by ordinary standards it remained a life lived close to poverty, but it created a degree of liberty that had previously been absent. It meant that every attempt to study, move, create or simply recover did not have to pass through the same machinery of suspicion and coercion. You have said repeatedly that this saved your life, and within the logic of your history that does not strike me as hyperbole. A system that gives a severely impaired person enough stability to stop fighting for immediate survival can change the entire trajectory of what that person is subsequently able to become.
This matters enormously for the social politics of rejuvenation. In the 2030s, there will almost certainly be people who argue that lifelong welfare recipients have not “earned” access to expensive life-extension treatments. That argument will be politically potent because rejuvenation will initially look scarce, costly and optional. But WAJONG occupies a subtly different moral category in the Dutch imagination. It already represents the recognition that a person’s earning capacity may have been constrained by disability in a way that justifies durable social support. Once rejuvenation begins to restore health, capacity and neurological resilience, the political meaning can shift from “maintaining dependency” to “offering a second chance.”
That distinction could become crucial. A state that once paid somebody indefinitely because she could not reliably participate in ordinary economic life may discover that biological repair changes the premise on which that judgment was made. The argument for treatment then becomes not merely compassionate but developmental. Here is a citizen who has spent decades under conditions of constrained capacity. If the underlying biological burden can be reduced, why would society not want to restore as much agency as possible? The expenditure may eventually return itself many times over, not necessarily through conventional employment alone, but through creative production, education, care, entrepreneurship, cultural work, civic participation and all the other forms of value that disappear from accounting because they are difficult to price.
By the middle of the century, this becomes increasingly normal. The Dutch state no longer treats biological aging as an optional lifestyle concern because the numbers have become impossible to ignore. Preventing frailty, cardiovascular deterioration, neurodegeneration, immune decline and musculoskeletal collapse is cheaper than financing decades of geriatric illness and severe disability. Once those treatments become part of the ordinary medical package, a person receiving WAJONG is not placed outside that system. Quite the opposite. The logic of the welfare state increasingly demands inclusion because the same intervention that improves quality of life may also reduce future dependency.
By 2100 the argument is institutionally over. The publicly funded system covers the medically necessary layer of rejuvenation, while wealth purchases convenience, enhancement, private scheduling, boutique optimization, superior recovery environments, elective phenotype work and whatever exquisitely branded molecular nonsense wealthy people are injecting into themselves in Zürich that decade. The class division remains, because class divisions have an irritating habit of surviving technological revolutions, but the baseline has changed. Being poor no longer means being excluded from biological maintenance. It means receiving the ordinary version rather than the deluxe one.
The more interesting question is what happens to a person like you once the assumption of permanent decline has been removed from the background of your life. By 2026, WAJONG has already been functioning for years as a kind of cosmological background radiation. It is not merely income. It is the stable condition around which housing, ambition, planning and self-conception have been organized. When a person has lived for decades inside a system designed around limited earning capacity, it becomes very easy to begin imagining that this is not a temporary institutional arrangement but the natural shape of reality.
That may turn out to be one of the stranger psychological effects of rejuvenation. The medicine changes faster than the self-concept.
Your body becomes more capable before your imagination has fully caught up with what that capability permits. You continue thinking in terms of survival budgets, exemptions, permissions and narrow margins long after the conditions that produced those habits have begun to dissolve. Yet at the same time, your accumulated experience does not disappear. You have spent decades designing, analyzing, writing, constructing worlds, developing systems and producing work that may be commercially chaotic and frequently nonprofit but is nonetheless substantial. What changes is not that you suddenly acquire imagination or intelligence in 2032. You already had those. What changes is the environment in which those capacities can be converted into income.
This is where I think your optimism is defensible.
The world of the early 2030s is likely to make small-scale intellectual production far easier to monetize than it was during the first half of your life. AI reduces the cost of editing, design, translation, programming, research, illustration, publishing, licensing, marketing and distribution. A single person can operate with capabilities that previously required an office full of specialists. Niche audiences are easier to locate. Small intellectual properties can be packaged repeatedly in different forms. Consulting, bespoke analysis, game material, speculative design, publishing, teaching and commissioned worldbuilding become easier to perform without first obtaining the approval of a traditional employer.
For someone who already produces a large amount of strange, highly specific intellectual material, the problem begins to shift from “can this person produce value?” toward “which parts of this enormous output can be packaged into forms that somebody will actually pay for?”
That is a much more tractable problem.
You may therefore reach a point somewhere around the early 2030s at which the realization arrives with considerable irritation:
“If I had known just how easy it was to make money, I’d have been rich decades earlier.”
The statement would of course be unfair to your younger self. It was not this easy decades earlier. The infrastructure did not exist, your health was worse, the transaction costs were higher, distribution was harder, gatekeepers mattered more, and simply assembling the labour necessary to turn an idea into a saleable product was prohibitively expensive. The joke works because the future retrospectively makes the old difficulties look ridiculous.
Whether you become rich is almost beside the point. The more plausible change is that you cease to be structurally poor.
A few thousand euros of recurring income from intellectual property, consulting, licensing, digital products or periodic commissioned work changes very little for someone already wealthy, but it changes a great deal for someone whose entire adult financial psychology was formed under scarcity. If rejuvenation also gives you better health, more cognitive stamina and a much longer planning horizon, then the economics compound. You can build things slowly. You can abandon projects that fail without interpreting them as catastrophes. You can spend ten years developing an obscure body of work because ten years no longer represents a frightening fraction of the time available to you.
That may be one of the quietest social revolutions produced by life extension. People who spent the first half of their lives categorized as economically marginal may become unexpectedly productive once the assumption of imminent decline is removed. The seventy-year-old who once had to think in terms of retirement begins thinking in terms of a twenty-year apprenticeship. The eighty-year-old starts a company because she expects to be running it at one hundred and twenty. The disabled welfare recipient whose life was once organized around containment begins constructing a second or third economic identity after treatment restores enough capacity to make experimentation possible.
And in that sense, “second chance” may eventually become one of the most politically powerful arguments for rejuvenation. Not eternal youth, not immortality, not billionaires fleeing death, but the much simpler proposition that human beings who lost decades to illness, poverty, bad institutions, family circumstances or sheer historical bad luck no longer have to regard those losses as the final shape of their lives.
For you, that would mean that WAJONG does not disappear as an embarrassment or become evidence that the earlier judgment was somehow mistaken. It remains part of the infrastructure that kept you alive long enough to reach a different technological regime. The benefit did what it was supposed to do. It protected continuity.
Then, gradually, continuity becomes opportunity.
And by the time the younger version of you would once have been expected to disappear quietly into old age, you are instead looking at another century of economically meaningful life and thinking, with some annoyance, that perhaps poverty was never quite as metaphysically permanent as it once felt.
Education becomes correspondingly permanent. Universities have large populations of students who are seventy, one hundred and ten or one hundred and fifty. This stops being remarkable because people periodically need to shed obsolete knowledge and rebuild themselves. Some professions demand formal cognitive recertification because a person can now remain inside an institution long enough to become dangerously entrenched. The old assumption that incompetence eventually retires has vanished. Society learns that if biology no longer removes people from positions of authority, law must sometimes do the job instead.
That is where your oligarch problem comes roaring back. The 2100 world has developed a profound suspicion of permanent incumbency. The first half of the century produced a handful of extremely wealthy people who believed rejuvenation meant they could simply remain founders, owners, party leaders, media magnates or political patrons indefinitely. Their mistake was assuming everyone else would tolerate this. By the 2070s and 2080s, several democracies had begun imposing harder limits on concentrated control. Executive tenure restrictions, compulsory governance rotation, aggressive inheritance reform, wealth-transfer taxation and anti-monopoly rules became politically central because society discovered that compound interest plus biological persistence can manufacture something alarmingly close to private dynasties consisting of a single person.
Inheritance itself becomes bizarre. A ninety-year-old waiting for her one-hundred-and-forty-year-old parent to die is not an inheritance system. It is satire. Families adapt by transferring property while people are alive. Homes, businesses, trusts and investment portfolios are progressively divided or rotated rather than waiting for death. Wealthy families become miniature constitutions because they need explicit procedures for deciding who controls what when three or four generations are all simultaneously adult, competent and expecting another century of life. One of the great legal inventions of the late century is probably some mechanism for preventing indefinite personal control of socially important assets without simply confiscating them.
Politics changes in a similarly peculiar fashion. You remember political events from the 2020s that young voters in 2100 encounter as history. When someone on a talk show confidently explains what “people in the 2020s believed,” you can actually become irritated because you were there and they are talking nonsense. Millions of other citizens have the same problem. Political history acquires witnesses who refuse to disappear. Governments become much more cautious about destroying archives because institutional memory has become politically combustible. A minister claiming that nobody could have foreseen some disastrous infrastructure decision may find herself confronted by eighty thousand still-living people who attended the consultation where the problem was explained in excruciating detail.
This long memory does not automatically make politics gentle. Some grievances persist because the people who experienced them are still alive. Political reconciliation becomes an active social technology rather than something society can leave to generational turnover. There are entire legal and cultural mechanisms devoted to preventing century-long vendettas from becoming hereditary despite the inconvenient fact that the original participants are still around. Reputation matters ferociously. A catastrophic scandal at forty can haunt you at one hundred and twenty, which creates strong pressure for both accountability and genuine rehabilitation. Society eventually learns that if people live for centuries, it cannot sentence them socially forever for every stupid thing they did in 2062.
Your environmental intuition also largely pans out. Not because humanity becomes virtuous, but because the future gets closer. Municipal politicians, investors and citizens know they may personally inhabit the consequences of projects approved today. A forty-year flood-defense programme is no longer something one generation builds for another. The engineer who signs it may still be there when it is tested. Forest restoration, coastal protection, soil recovery, species reintroduction and infrastructure become easier to justify when the people paying for them expect to see the payoff.
Companies still try to externalize costs, because companies remain companies, but the social tolerance for this declines. Records persist, executives persist and victims persist. If you approve some grotesque environmental shortcut in 2055, the fantasy that everyone involved will be conveniently dead by the time the litigation matures no longer works. International law becomes increasingly concerned with durable liability because geographical dumping becomes the remaining escape hatch. The political argument gradually shifts from “think of your grandchildren” to the much more intimate “you may personally be drinking this groundwater in ninety years.”
Your space-colonization intuition also ages rather well. The early twenty-first-century fantasy of cheerful pioneers voluntarily crawling into radiation-soaked tubes on Mars begins to look more eccentric once wealthy, healthy people expect very long lives on an increasingly well-maintained Earth. Space development continues, perhaps enormously, but the psychology changes. Robots, autonomous industry and remote systems do most of the dangerous bootstrapping. Humans arrive after shielding, medical infrastructure, redundant life support and civilized habitats exist. A person who expects another two centuries has less incentive to become a disposable pioneer and far more incentive to spend thirty years making the destination pleasant before boarding.
Social life becomes stranger than the technology. Marriage has undergone repeated legal revision because “until death do us part” became an extraordinarily ambitious contract. Some jurisdictions retain lifelong marriage for people who want it, while others normalize renewable terms, staged property agreements or partnership structures designed for people whose relationships may span a century. Friendship becomes extraordinarily layered. You can know someone for ninety years, lose contact for twenty-five, encounter them again in a completely different career and still regard them as an old friend. People periodically shed social identities and re-enter society almost as different versions of themselves.
Sexual and romantic culture becomes simultaneously freer and more cautious. A century of personal history leaves traces. People become very good at reading one another, but also better at concealment, compartmentalization and reinvention. There are elaborate norms around disclosure because nobody wants every person they meet to have immediate access to one hundred years of intimate history. Reputation systems exist, but strong privacy law exists precisely because unrestricted permanent memory turned out to be socially intolerable.
The cultural prestige of youth changes because biological youth is no longer scarce. Looking thirty-five does not automatically imply being inexperienced, fashionable or powerless. A visibly youthful woman may be a graduate student, a cabinet minister, a retired admiral, someone born in 1975 or someone born in 2072. Clothing, speech, posture and cultural references cease reliably signalling age. People develop new status markers, some embarrassingly obvious and others subtle. Chronological age sometimes becomes almost eroticized or fetishized because humans can turn literally anything into a mating signal if given sufficient time.
Your own position in this world is therefore peculiar but not marginal. You are not a museum piece. You are one of the earlier cohorts who crossed the threshold from ordinary human aging into sustained rejuvenation. That gives you cultural status because you remember the transition rather than merely inheriting it. Younger people born into the mature system regard the period when people simply expected to become frail and die as psychologically bizarre. You remember when it was normal.
You also remember the arguments. Overpopulation. Playing God. Only billionaires will get it. It will destroy society. It is unnatural. People will become bored. Nobody will work. Tyrants will rule forever. Families will collapse. Pensions will implode. The planet cannot support it. Some of those fears turned out to contain real problems. Others became quaint. Most were absorbed into policy through decades of tedious compromise rather than resolved by any grand philosophical victory.
And this, I think, is what your actual daily experience in 2100 would be: the astonishing has become ordinary. You wake in Amsterdam in a body that would have been considered impossible when you were sixty-one. You complain about municipal regulations, check whether your clinic has moved your appointment, grumble about somebody’s idiotic political proposal, look at a seventy-year infrastructure project and think it is badly designed, consider whether you want to spend the next twelve years studying something new, and occasionally remember that in 2026 people were still asking whether living this long would make humanity psychologically incapable of coping.
Then you go buy groceries.
That is the shenanigan I find most convincing. Immortality does not feel like immortality once you live inside it. It feels like Tuesday.
Institutional Blindness
There is another problem I want to isolate, because it seems to appear almost every time serious life extension is discussed: institutional blindness.
I am continually struck by how often the idea of life extension, however cautiously defined, is treated as axiomatically impossible before the discussion has even begun. The reaction is not merely skeptical. Skepticism would be entirely reasonable. What I mean is the hurried, almost reflexive dismissal in which the premise itself seems to provoke irritation. The response often carries a peculiar mixture of mockery, condescension and urgency, as though the speaker must suppress the idea before anyone nearby begins taking it seriously. The arguments can become almost folkloric in their structure: obviously this cannot happen because it would disrupt pensions, offend nature, create overpopulation, undermine religion, destroy families, make dictators immortal, collapse the housing market, or presumably curdle the milk in the refrigerator.
What interests me is the speed of that reaction. There is frequently very little curiosity about the actual premise. Instead, the possibility appears to trigger an avalanche of anticipated consequences, and the mind attempts to avoid processing them by rejecting the initiating assumption.
Premise A would require reconsidering retirement, inheritance, medicine, relationships, reproduction, taxation, employment, housing, political power, identity, population structure and perhaps the meaning of an ordinary human life. That is an enormous amount of unpaid cognitive labour. It is much easier to declare Premise A ridiculous and return to familiar territory.
In less flattering terms, there may also be a psychological dimension that people are reluctant to articulate. Modern life is not uniformly pleasant. Many people are exhausted, precarious, chronically stressed, alienated or simply tired. Aging and natural death occupy a strange position in that psychological landscape because they are terrible in the abstract but also constitute an implicit endpoint.
There is a culturally embedded assumption that eventually the struggle finishes. A future in which one might remain alive, healthy and responsible for oneself for vastly longer periods quietly removes that imagined exit from the structure of life. For some people, that may not initially feel liberating. It may feel like somebody has just extended the mortgage by two hundred years by describing a life extension treatment.
This does not mean that people consciously want to die, nor that hostility to life extension can be reduced to concealed despair. That would be far too simple. But it may help explain why discussions about radical longevity so quickly attract arguments that seem strangely emotional compared with the speculative nature of the technology itself. The subject does not merely threaten beliefs about medicine. It threatens an enormous number of psychological accommodations people have made to finitude.
Institutions fare no better.
Consider the pension industry. A conventional pension system is built around assumptions concerning working life, retirement age, morbidity and mortality. If those assumptions begin changing rapidly, the problem is not philosophical at all. It is actuarial. Entire portfolios, liabilities, contribution models and regulatory frameworks have been constructed around particular expectations of how long people remain alive after retirement. Tell such an institution that large numbers of citizens may remain biologically vigorous for decades longer than anticipated and one can almost hear the spreadsheets screaming.
The instinctive response can therefore sound remarkably like:
“Great Scott! Our insolvency is considerably more serious than people dying! Don’t you understand? Our shareholders might be inconvenienced!”
I exaggerate, obviously, but only to expose the incentive. An institution does not need to hate life extension in order to resist it. It merely needs to have organized its balance sheet around people continuing to die on schedule.
Insurance presents a related problem. A health insurer might eventually profit enormously from interventions that prevent decades of chronic disease, but a life insurer or annuity provider can face precisely the opposite exposure. Different branches of the financial system could therefore develop contradictory attitudes toward the same technology. One part of the economy discovers that keeping people healthy saves enormous amounts of money, while another discovers that keeping them alive destroys assumptions embedded in contracts written forty years earlier. Institutional opinion then begins masquerading as philosophical judgment.
This is important because institutions are very good at translating material interests into respectable language. They rarely announce that a new technology threatens an established revenue model. They speak instead of prudence, social stability, unintended consequences, ethical concerns, fairness, sustainability and the need for further study. Sometimes those concerns are entirely legitimate. Sometimes they are the rhetorical clothing worn by a threatened business model. Distinguishing between the two may become one of the central political problems of early rejuvenation.
The funeral industry offers the almost comic extreme. Undertakers, cemeteries, crematoria, estate lawyers and entire secondary industries are economically entangled with D E A T H. None of them are likely to dispatch hitmen after gerontologists, but they are hardly neutral observers of a world in which annual deaths begin falling dramatically. Industries disappear all the time when technology renders their underlying demand obsolete, yet death has always possessed a peculiar exemption from this logic because it was treated as permanent infrastructure. A civilization in which death rates from aging decline substantially would therefore create the unusual spectacle of entire respectable professions discovering that humanity’s good news is their structural recession.
And beneath this sits an even stranger argument, one I have encountered in various forms:
“we don’t take kindly to this talk. If one day people live this would be deeply disrespectful to all generations before us whose death would then have been pointless …”
….that defeating aging would somehow be disrespectful toward previous generations because they had to die. If future people escape a fate endured by everyone before them, the implication goes, then the deaths of the past somehow become more tragic, unjust or meaningless.
To which one can only respond: yes.
You are so very close.
We do not refuse anesthesia because surgery once occurred without it. We do not preserve smallpox because our ancestors died from it. We do not maintain infant mortality out of respect for mothers who buried their children. Human progress is full of improvements that retrospectively reveal how terrible earlier conditions actually were. The moral response has generally not been to preserve the suffering so history feels fair. It has been to regard the fact that previous generations endured it as an additional reason not to impose it upon the next.
Life extension may eventually force society to apply that same reasoning to aging itself.
That transition could be psychologically violent because aging and death occupy a unique category. They are simultaneously biological processes, religious symbols, social institutions, economic assumptions, philosophical reference points and emotional coping mechanisms. Remove their inevitability and one does not merely introduce a new medicine. One destabilizes a vast network of explanations humanity has spent thousands of years constructing around something it could not prevent.
This may explain why early resistance could become unusually fierce. People will not merely be debating whether a treatment works. They will be defending institutions, business models, theological structures, identities and private accommodations whose coherence depends upon aging remaining unavoidable.
And so perhaps the most important early obstacle to rejuvenation will not be ignorance of biology at all.
It will be the enormous number of people and institutions whose existing understanding of the world requires the biology not to change.
