I understood the article and offered my own solution option, as best as I could. I may not be particularly brilliant, but this is how I see the situation.
Thank you for your patience
“…an enormous number of required therapeutic interventions across all aging trajectories.” Yet in the world of mechanical systems, aging also affects an enormous variety of components, structures, and functional parts. Cars may fail because of the engine, boats because of the hull, and aircraft because of entirely different mechanical weaknesses. Nevertheless, the underlying molecular cause connecting the aging and failure of all these systems is remarkably simple: the reaction of iron with molecular oxygen. Whether on land, at sea, or in the air, the fundamental driver of mechanical aging is rust.
A similar conceptual framework may apply to biological organisms. The immense diversity of adaptive structures — organs, tissues, and specialized cellular systems that evolved for survival — may ultimately converge on one, or perhaps only a few, fundamental molecular causes of aging.
Would you more lean towards hallmarks of aging, or some other causes?
With hallmarks it looks like that the approach has more or less failed, hasn't it?
Everything boils down to the definition of aging — a decline in the organism’s viability with age. This encompasses the lifelong changes (evolution) of the 240 types of cells in our body. It includes the adaptation of these cells through transdifferentiation. It includes the loss of irreplaceable cellular components. It includes the replacement of various structures with connective tissue, hypertrophy, and many other natural life processes. And much more besides — including the formation of vicious cycles, such as pathological cell senescence → disruption of the extracellular matrix → even more pathological cell senescence.
All of this needs to be reversed back to the ideal norm — youth. Some aspects can be simplified, and some processes will be reversed in a complex, interconnected way, but there is still a tremendous amount of work to be done.
The correctness of my view is proven by the current absence of effective geroprotectors for healthy people after age 50, the lack of a general theory of aging, and the lack of a gold standard for determining biological age.
"Full natural body has problems in donors availability, and won't be a subject for universal immortalism"
It seems to me that as soon as it becomes clear that immortality is possible — and especially once there are practical, real-world examples — a significantly larger amount of intellectual and material resources will be poured into solving the problem. This is the “first successful case” effect.
And then new technical solutions will emerge for the problems that we currently have to solve head-on, in the most direct and difficult way.
Sure, but 1 iteration on attempt to grow a body will cost around 20 years. So 4 iterations, and the scientist is dead. You can do multiple at once, but still, you can fail > 4 times. If you attempt to grow them faster and slow them down - it's also adding the complexity layer that could contain backfires.
1. There are indeed many problems. But what position are we actually in?
On the one hand, we have a head that is falling apart on a perfusion system. On the other hand, the entire body — along with every system (immune, cardiovascular, endocrine, respiratory, etc.) and every organ (liver, kidneys, heart, lungs, etc.) — is also falling apart in much the same way as the head, each with its own specific issues requiring individualized therapy. As these systems and organs deteriorate, they accelerate the destruction of all the others, including the brain.
That is why we have to cut away as much as possible. The less flesh remains, the fewer problems we face from age-related degradation.
2. Regarding the challenges of creating an artificial body: interaction with artificial surfaces is a solvable problem. There are well-known examples of a person living with an artificial heart for 555 days or being on ECMO for 100 days. In this case, the liver is a consumable organ that can be replaced. All blood components can be produced artificially, including from the patient’s own cells — although this is still very expensive. At the same time, we are developing therapeutic versions of leukocytes and other blood cells in parallel.
3. As long as a decrepit biological body remains, it will be impossible to focus properly on therapy for any individual part (including the brain), because negative signaling from pathologically altered organ systems will reduce the effectiveness of treatment and accelerate the destruction of the restored organ. In contrast, an artificial or young biological body — along with artificial blood — will send powerful therapeutic signaling to the brain, whereas the old body actively destroys it.
I suggest you to create a separate discussion of the concept of the detached head.
1. Perfusion system may destroy the head same fast, as non-natural pulse may create turbulence in already weak blood vessels, which are the hardest part to solve in the brain.
2. So far ECMO requires a lot of medical personnel to support, and we don't know the long-term consequences of 555 days on it. Replacing liver will require one more donor OR bioengineering liver which is even harder. No-one yet have grown a bioprinted liver.
3. I don't have enough data pro or against this argument.
The first real longevity therapies probably won’t be called longevity therapies.
Below is the median scenario: not a single “cure for aging,” but an infrastructure for managing age-related risk.
The board as it stands
AI is becoming the main tool of biotech: from molecule generation and in silico screening to wet labs, trial design, and patient selection. But biology remains slow. Even accelerated discovery does not instantly become therapy.
New players from the AI industry are impacting biotech: Dario Amodei, Sam Altman, Demis Hassabis, and Alex Zhavoronkov, who stands apart because of his direct experience in AI drug discovery. They have, in different ways, shown interest in extending life. But their influence is not yet showing up as finished therapies. It is showing up as a shift in tools, capital, and ambition.
The main asset of future longevity medicine is the longitudinal history of the organism: genome, blood tests, imaging, diagnoses, drugs, device data, functional status, responses to interventions, and death.
Pharma is adopting AI, but it still owns the main pipeline: development, clinical validation, manufacturing, registration, and delivery of therapies. The success of GLP-1 drugs showed that one drug can affect several systems at once. But pharma will move where there is intellectual property protection, manageable financial risk, and a clear path to reimbursement.
Regulators still have not created a direct path for “aging therapies.” There is no simple way to quickly prove an effect in humans. TAME is an early signal, important not because of metformin itself, but because it tries to test whether a therapy can delay several age-related diseases at once. For now, it is an exception, not a working regulatory route. That is why the industry still moves through proxy diseases: diabetes, fibrosis, sarcopenia, cardiovascular risk, neurodegeneration, and frailty.
Above all this hangs the silver wave of demographics. Pensions, healthcare, and long-term care already take up a huge share of public spending and will keep growing as populations age. This turns longevity from a biohacker dream into a budget problem for states.
Aging will not be called aging at first
The first life-extension therapies will almost certainly enter the market not as “anti-aging drugs,” but as drugs against specific age-related diseases: diabetes, fibrosis, sarcopenia, cardiovascular risk, neurodegeneration, frailty, chronic inflammation, or organ failure.
The reason is simple: these diseases have patients, endpoints, regulatory paths, reimbursement, and intellectual property protection. “Aging” as a direct indication does not.
The adoption pattern will resemble GLP-1s: a drug begins with one indication, then gradually turns out to be broader than the original disease. This is how the first weak “anti-aging drugs” may emerge as a side effect of ordinary pharmaceutical franchises.
The first scalable interventions will probably not be radical tissue rejuvenation, but pharmacological risk-shifting: small molecules, peptides, metabolic drugs, anti-inflammatory and antifibrotic classes. They may look biologically unimpressive: slightly lower inflammation, slightly better metabolism, slightly less fibrosis, slightly lower risk of cardiovascular events or frailty. But even a moderate risk shift across large populations will generate preserved QALYs — quality-adjusted life years. That is why these therapies will be desirable for patients, payers, and states.
The TAME trial stands apart. It is not just another side door, and it is not full recognition of aging as an indication. It is a transitional form: a known drug, familiar clinical safety logic, but a new attempt to test several age-related outcomes at once. Its importance is not metformin. Its importance is the design: it shows how the industry may move from treating individual diseases to testing the trajectory of aging.
The measurement market will arrive before the therapy market
In parallel, the measurement market is already growing. Aging is being sold not as treatment, but as a map of decline: aging clocks, multi-omic panels, wearable signals, functional tests, imaging, inflammatory markers, and indicators of muscle, vascular, brain, and organ status.
But these biomarkers are still not strong enough to prove “slowing aging” as a medical fact. They work as shadows around ordinary indications. A drug treats diabetes, obesity, fibrosis, or cardiovascular risk, and at the same time shifts signs of systemic decline.
At this stage, biomarkers do not say: “we treat aging.” They say: “the effect is broader than one diagnosis.” This is not yet a language of control. It is a language of suspicion.
But this is where closed-loop aging medicine begins. At first, biomarkers will be beautiful reports for wealthy patients and additional signals in clinical trials. Then they will start influencing patient selection, dosing, combinations, discontinuation, and reimbursement. At some point, the measurement market will stop being a wellness industry and become the sensory layer of aging medicine, mostly likely through imaging.
Longitudinal multimodal data becomes the core asset
The main asset of future longevity medicine is the longitudinal history of a human body. To see aging, you need to see the trajectory: blood tests, medical imaging, diagnoses, drugs, surgeries, infections, sleep, activity, diet, wearables, functional status, hospitalizations, responses to interventions, and death.
That is why owners of longitudinal medical data will become the new biomedical aristocracy. For life extension, what matters is not just data, but data with feedback: intervention → result → new measurement. It is important to see millions of longitudinal patient histories over time: when frailty begins, how vascular risk accelerates, which signals predict dementia, why one patient responds to therapy and another does not.
AI here is a system for finding trajectories: hidden subtypes of aging, trial cohorts, risk patterns, therapeutic responses, and signals that actually change outcomes.
That is why the fight for longevity will be a fight for longitudinal data: clinics, insurers, pharma, states, wearable companies, and diagnostic platforms will all try to connect measurement, intervention, and outcome. The winners will be those who can prove: this signal helps choose an action that changes the result.
From biological age to tissue trajectories
Biological age as a single number is too crude. Aging is not one arrow and not a set of independent organs. It is a network of linked trajectories. Vessels, immunity, metabolism, muscles, brain, liver, kidneys, and connective tissue can age at different speeds, but they often pull each other through inflammation, hormonal signals, vascular damage, fibrosis, and senescent cells.
That is why the next step is the transition from general age to tissue and system clocks. Aging will be sliced into trajectories: metabolic, vascular, immune, muscular, cognitive, liver, kidney, fibrotic, and inflammatory.
At first, these clocks will be noisy and overvalued. They will be sold as beautiful reports: “your vessels are older than your passport,” “your muscular system is declining faster,” “your inflammatory profile is bad.” Much of this market will look like premium wellness with a scientific interface.
But the meaning will gradually change. Tissue clocks will become the basis for choosing interventions. If the muscular trajectory is accelerating — one protocol. If vascular — another. If immune — a third. If fibrotic — a fourth.
This is an important transition. As long as a person has only “biological age,” it is unclear what to do. If there is a map of tissues and systems, action becomes possible: whom to include in a trial, which therapy to choose, what to monitor, when to intensify, when to stop, when to change the protocol.
At this stage, aging becomes a segmented market for the first time: not one “anti-aging” market, but markets for managing system-specific decline.
Drifts in tissue complexes become the real target
Once aging is split into tissue trajectories, the target will not be “the whole organism” or isolated organs. It will be early drift inside tissue complexes: muscle-bone, vascular-endothelial, immune-inflammatory, liver-metabolic, kidney-vascular, brain-vascular, connective tissue-fibrotic.
This is the real shift. Medicine usually waits until drift becomes disease: sarcopenia, fibrosis, chronic kidney disease, heart failure, dementia, frailty. Longevity medicine will try to intervene earlier, when the tissue complex is still functional but already moving in the wrong direction. Before any risk occurs.
The goal is not just to treat a diagnosis, but to push a drifting tissue complex back toward a more resilient state: better muscle quality, less fibrotic drift, stronger vascular function, recalibrated immune tone, preserved organ reserve, slower neurovascular decline.
This will look closer to real rejuvenation, but it will also be riskier. Push regeneration too hard and you raise cancer risk. Suppress inflammation too much and you weaken defense. Remodel tissue too aggressively and you can destabilize it.
These therapies will still be sold under the language of preventive medicine, but underneath, the target will be aging as early drift in tissue complexes.
Closed healthcare loops instead of one-off therapies
The main turning point will not come when the first strong drug appears, but when aging is managed as a controllable process.
A one-off therapy says: “here is the drug, take it.” A loop says something else: “we measured your trajectory, selected an intervention, checked the response, changed the dose, added a second layer, removed what was unnecessary, updated the forecast.”
The formula of future aging medicine will be simple: measure → predict → intervene → check → update protocol → scale.
Here, AI will matter not as a chatbot and not as a “digital doctor,” but as a trajectory-control system based on collected multimodal data: who is aging faster, why, which therapy will work, where the side-effect risk is, when the protocol needs to change.
At first, these loops will appear in premium longevity clinics. In extreme form, premium self-tracking projects are already trying to imitate this. The loops will be expensive, noisy, and partly theatrical: many tests, beautiful panels, off-label prescriptions, personal protocols, constant monitoring. But because the biomarkers and therapies are not yet solved, much of the effect will be weak.
After biomarkers capable of detecting early drift and tissue-specific therapies appear, more serious players will take over this approach: insurers, clinical networks, and states.
At that point, the state may start to function like a population-scale longevity clinic, deploying systems for managing age-related risk: screening, stratification, intervention, outcome measurement, protocol updates, and scaling.
Countries with centralized healthcare systems, connected longitudinal medical records, and the ability to launch preventive programs from the top will have a special advantage. Fragmented private medicine can experiment faster on wealthy patients, but it is harder for it to turn this into a national feedback system.
GLP-1 as a rehearsal for longevity therapies
When a drug appears systemically useful, more people want access to it than the original indication expected. Some of that demand will be justified. Some will be premature. Some will simply be the desire not to be left outside the medicine of the future.
Doctors will argue over prescribing criteria. Insurers will resist coverage because the costs appear now, while the savings may appear years later and benefit another insurer. Patients will not speak the language of immortality. They will speak the language of prior authorization, price, shortages, BMI, diabetes, heart risk, and insurance coverage.
GLP-1s revealed another bottleneck: inventing a therapy is not enough. It has to be manufactured, delivered, paid for, and kept available. For life extension, this becomes a separate problem, because life-extension therapy will not be just a drug, but diagnostics, monitoring, and follow-up. The winner will not only be whoever invents the intervention, but whoever can produce and deliver it at scale.
That is why the first conflicts around life extension will look like thousands of small disputes between patients, doctors, insurers, regulators, and manufacturers over access to drugs that prevent — or claim to prevent — decline, disability, and age-related disease.
China’s advantage may be administrative, not scientific
In the West, aging will become a medical object from the bottom up: through indications, insurance conflicts, clinical guidelines, patient pressure, and reimbursement battles.
China may not discover the decisive molecule first. But it may be faster at turning a medical hypothesis into a public-health program. Aging pressures healthcare, pensions, families, labor markets, and long-term care at the same time. That makes interventions against frailty, dementia, and disability potential instruments of state strategy.
China’s national dementia plan is not longevity medicine. But it shows the template: screening, early detection, standardized diagnosis, intervention, workforce training, care infrastructure. Age-related risk becomes a route.
The Chinese path does not mean “no bioethics.” After the CRISPR babies scandal, China strengthened formal oversight of human-subject research, biomaterials, and medical data. The difference is institutional: bioethics, clinical deployment, demographic strategy, industrial policy, and state capacity sit closer together than in the Western model.
The upside is speed: city pilot → provincial program → national protocol → local production → cost reduction. The downside is also obvious: premature scaling, less individualization, uneven access, and crude protocols.
But China may be the first to build not an anti-aging pill, but an administrative-medical operating system for age-related risk.
The access problem
The main political phase will begin not when therapies are absent, but when they exist and are not available to everyone.
At first, access will be rare: premium clinics, wealthy patients, good insurance, corporate programs, specific indications, proactive states, and cities with strong medical infrastructure. Aging will be slowed earlier there.
Payers will resist coverage, especially in private insurance systems. Their problem is the short horizon: why pay today to prevent a disease in 10–15 years if the patient may switch insurers in three?
When therapies start working, biomarkers will become the language of financial dispute. Patients will argue that refusal of coverage is not savings, but payment for future dementia, disability, heart attack, or care. Insurers and states will use the same biomarkers to restrict access.
The main inequality will be between systems that have built infrastructure for managing aging and systems where aging remains the natural background of decline. The difference will be visible not only in blood tests, but in gait, memory, muscle, independence, hospitalizations, and years without disability.
Oases of slowed aging and zones of ordinary decline will appear. People of the same chronological age will start to look as if there are 30 years of biological difference between them.
Access politics and the normalization of immortalism
When therapies begin to produce noticeable effects, grassroots access politics will emerge around them.
This will not be an abstract fight for “immortality.” People will demand concrete things: cover drugs that reduce future risks; provide access to therapies that delay disability; stop denying protocols that preserve independence; allow generics; expand diagnostics; remove pointless prior authorization.
Coalitions will appear: patients, families, older people, doctors, workers, unions, and possibly employers. In the United States, they will pressure insurers and Medicare. In Europe, state healthcare systems. In poorer countries, international access, cheap versions, diagnostics, and delivery infrastructure.
This is how immortalism will begin to normalize. Not as a philosophy of eternal life, but as an extension of ordinary medicine: less dementia, less frailty, less pain, more years without dependence on care.
Biohackers and early immortalists will create noise, envy, and symbols. But they will not own the main transition. Patients, payers, clinics, pharma, states, and families will — because they will not want to pay for decline if decline can be delayed.
Immortalism will not win first as a philosophy. First, a smaller idea will win: aging can be measured, segmented, and slowed. Then another: access to that control should be normal. Only after that will death from aging begin to look less like a natural ending and more like a technical and political failure.
