Three Specters of Immortality

Franco Cortese
By Franco Cortese
Ethical Technology

Posted: Sep 24, 2013

I would like to address what I consider to be three common criticisms against the desirability and ethicacy of life-extension I come across all too often – three specters of immortality, if you will. These will be Overpopulation (the criticism that widely-available life-extension therapies will cause unmanageable overpopulation), Naturality (the criticism that life-extension if wrong because it is unnatural), and Selfishness (the criticism that life-extension researchers, activists and supporters are motivated by a desire to increase their own, personal lifespans than by a desire to decrease involuntary suffering in the world at large).

But first I would like to comment on why this would be important. I would consider two of the three critiques – namely the naturality critique and the selfishness critique – to be largely unfounded and vacuous; I don’t think they will be real worries when comprehensive life-extension therapies arrive. I think that the overpopulation critique does have some weight to it; we do in fact need to plan for and manage the effects of a growing population, but that it is wrong in assuming that such affects will be unmanageable.

So if at least 2 of these 3 critiques are largely unfounded, then what’s the worry? Won’t they simply disappear when life-extension is achieved, if they are really so baseless? Well, yes, but the possibility of their turning out to be right at the end of the day is not what makes them worrying.

What makes them worrying is the fact that they deter widespread support of life-extension from the general public, because they stop many people from seeing the advantage and desirability of life-extension today. A somewhat common, though thankfully not predominant, attitude I find from some longevity supporters is that work is being done, progress is being made, and that the best course-of-action for those who want to be around to benefit from the advances in medicine already on the developmental horizon is simply to live as healthily as we can today while waiting for tomorrow’s promise.

I don’t think this attitude necessarily deters progress in the life-extension field, but I certainly don’t think it helps it very much either. I think such people are under the pretense that it will take as long as it needs to, and that there is nothing the average person can really do to speed things up and hasten progress in the field. Quite to the contrary, I think every man and woman in this room can play as central a role in hastening progress in the field of life extension as researchers and scientists can.

This is largely due to the fact that just what is considered worthy of scientific study is to a very large extent out of the hands of the average scientist. The large majority of working-day scientists don’t have as much creative license and choice over what they research as we would like to think they do.

Scientists have to make their studies conform to the kinds of research that are getting funded. In order to get funding, more often than not they have to do research on what the scientific community considers important or interesting, rather than on what they personally might find the most important or interesting. And what the scientific community considers important and worthy of research is, by and large, determined by what the wider public considers important.

Thus if we want to increase the funding available to academic projects pertaining to life-extension, we should be increasing public support for it first and foremost. We should be catalyzing popular interest in and knowledge of life-extension. Strangely enough, the objective of increased funding can be more successfully and efficiently achieved, per unit of time or effort, by increasing public support and demand via activism, advocacy and lobbying than by say direct funding, period.

Thus, even if most of these criticisms, these specters of immortality, are to some extent baseless, refuting them is still important insofar as it increases public support for life-extension, thereby hastening progress in the field. We need massive amounts of people to wake up and very explicitly communicate their desire for increased funding in biomedical gerontology, a.k.a. life-extension. I think that this is what will catalyze progress in the field – very clear widespread demand for increased funding and attention for life-extension.

This is something I think each and every man and woman here today can do – that is, become a life-extension activist and advocate. It is not only one of the easiest ways in which you can contribute to the movement – it may very well be the most important and effective ways that you can contribute to the movement as well. Send an email to the International Longevity Alliance (, an organization dedicated to social advocacy of life-extension, who is compiling a list of life-extension advocates and networking them together. Arrange and organize your own local life-extension rally or demonstration, like the one held last year in Brussels. This could be as easy as holding up signs supporting scientific research into aging in the most traffic-dense location in your local area, recording it and posting it on YouTube.

And so, without further ado, I’d like to move on to the three specters of immortality.

1. The Unmanageable Overpopulation Critique

Firstly, I’d like to turn the third specter of immortality – a critique of the possible undesirable societal repercussions of life-extension. The most prominent among these is the critique of overpopulation – namely that the widespread availability of life-extension therapies will cause unmanageable overpopulation and a rapid depletion of our scarce resources.

I think this critique is really the only one that’s a real worry. That is because potential negative societal repercussions of life-extension are a real possibility, and must be appropriately addressed if they are to be avoided or mitigated. And don’t get me wrong – they are manageable problems that can be handled if we make sure to plan for them sufficiently, and allocate enough attention to them before their effects are upon us.

According to some studies, such as one performed by S. Jay Olshanksy, a member of the board of directors for the American Federation of Aging Research (and the foremost advocate and promulgator of the Longevity Dividend) estimate quite surprisingly that if the mortality rate dropped to zero tomorrow – that is, if everyone in the world received life-extension therapies comprehensive enough to extend their lives indefinitely – we would experience a rise in population less than the growth in population we experienced following the Post-World-War-II baby-boom.

Global society has experienced dramatic increases in population growth before – and when that happened we extended and added to our infrastructure accordingly in order to accommodate them. When significant increases in life-extension begin to happen, I expect that we will do the same. But we must make sure to plan ahead. Overpopulation will be an insoluble problem only if we ignore it until its perceptible effects are upon us.

Luckily, there are a number of existing solution-paradigms to other, somewhat related problems and concerns that can be leveraged to help mitigate the scarcitizing effects of overpopulation on resources and living-space.

Contemporary concerns over the depletion of non-renewable resources, such as but not limited to climate change, can be leveraged to help lessen the detrimental effect overpopulation might have on non-renewable resources.

Another contemporary solution paradigm we can leverage to help mitigate the detrimental effects of overpopulation on living-space is seasteading. This is the notion of creating permanent dwellings and structures at sea, essentially floating cities, outside of the territory of governments – more often than not to get around legal complications relating to whatever the prospective seasteaders wish to do. This movement is already bringing about designs and feasibility studies relating to the safe construction of very large floating cities.

The most common solution-paradigms proposed to combat the problems of resources and living-space are space-colonization and regulating how many children people can have. I think that long before we turn to these options, we will begin to better maximize the existing living-space we have. 75% of the earth’s surface area is water. I think that we will colonize the oceans long before space-colonization becomes a more economically-optimal option. Further, we currently don’t use the living-space we have very well. We live on the surface of a sphere, after all. There is nothing in principal preventing us from building taller and building deeper. We can take from existing proposals and feasibility studies pertaining to megastructures – that is, very large man-made structures – to build much bigger than we currently do.

Another existing field that can help lessen the potential resource-depleting effects of a growing global population is agricultural labs, indoor farming systems and vertical farms. Such systems are in use today for large-scale food production. This would allow us to take all the space we currently have devoted to agriculture (roughly 40% of earth’s total land-area according to some estimates – see here and here) and move it underground or indoors.

Thus overpopulation is a real worry, but we have the potential solutions to its problematic effects today. We can leverage several existing solution-paradigms proposed to combat several contemporary problems and concerns in order to manage the scarcitizing effects of overpopulation on resources and living space.

2. The Naturality Critique

I’d like to turn to the Naturality criticism now – The criticism that life-extension is unnatural, dehumanizing and an affront to our human dignity. – This could not be farther from the truth. The stanch revulsion we have of death is right; appropriate; a perfectly natural response.

Besides which, “naturality,” insofar as it pertains to humans, is an illegitimate notion to begin with. For we human beings, naturality is unnatural; we who have cast off animality in the name of mind, we who have ripped dead matter asunder to infuse it with the works of our mind – we who have crafted clothes, codes, cities, symbols, and culture. Since the very inception of human civilization, we have very thoroughly ceased to be natural, and to such an extent that unnaturality has become our first nature.

Firstly, one thing that I think undercuts the critique of naturality rather well is the known existence of biologically-immortal organisms. There are in fact known organisms where the statistical probability of mortality does not increase with age. Meaning that if one kept these organisms healthily fed and in a good environment for them, then they simply shouldn’t die. Not only is there proof of concept for biological immortality – but it can be found in nature unmodified by man.

Hydras, small freshwater organisms, do not undergo cellular senescence and are able to maintain their telomere lengths throughout continued cell division. The Jellyfish Turritopsis Nutricula can, through a process called cellular transdifferentiation, revert back to the polyp stage (an earlier stage in its developmental cycle) a potentially indefinite number of times.

Planarian Flatworms also appear to be biologically immortal, and can maintain their telomere length through a large population of highly-proliferative adult stem-cells. And if you can believe it, an organism as commonplace as the lobster also appears to be biologically immortal. Older lobsters are more fertile than young lobsters, and they don’t appear to weaken or slow down with age.

There is then such a thing as biological immortality. In biology it’s defined as a stable or decreasing rate or mortality from cellular senescence as a function of chronological age. Meaning that barring such accidents as being eaten by prey, such organisms should continue to live indefinitely.

I also think that this is great proof-of-concept for people who automatically associate the magnitude of the endeavor with its complexity or difficulty, and assume that achieving biological immortality is technically infeasible simply due to the sheer profundity of the objective. But in regards to naturality, I think the existence of such biologically-immortal organisms goes to show that there is nothing necessarily unnatural about biological immortality – because it has already been achieved by blind evolution in various naturally-occurring biological organisms.

Secondly, I think that the long history of seminal thinkers who have contemplated the notion of human biological immortality, the historical antecedents of the contemporary life-extension movement, help to combat the naturality criticism as well. Believe it or not, people have been speculating about the scientific abolition of involuntary death for hundreds of years at least.

As early as 1795, nearly 220 years ago, Marquis du Condorcet wrote

Would it be absurd now to suppose that the improvement of the human race should be regarded as capable of unlimited progress? That a time will come when death would result only from extraordinary accidents or the more and more gradual wearing out of vitality, and that, finally, the duration of the average interval between birth and wearing out has itself no specific limit whatsoever? No doubt man will not become immortal, but cannot the span constantly increase between the moment he begins to live and the time when naturally, without illness or accident, he finds life a burden?”

Here we see one of the fathers of the enlightenment tradition speculating on whether it is really that absurd to contemplate the notion of a continually-increasing human lifespan.

In 1773, 240 years ago, Benjamin Franklin wrote in a letter to Jacques Duborg, first praising the sagacity and humanity demonstrated by his attempt to bring animals back from the dead, and then describing what can only be a harkening of cryonics and suspended animation, where he wishes that there were a way for him to be revived a century hence, and witness the progress in science that had been made since the time of his death.

Your observations on the causes of death, and the experiments which you propose for recalling to life those who appear to be killed by lightning, demonstrate equally your sagacity and your humanity. It appears that the doctrine of life and death in general is yet but little understood...

I wish it were possible... to invent a method of embalming drowned persons, in such a manner that they might be recalled to life at any period, however distant; for having a very ardent desire to see and observe the state of America a hundred years hence, I should prefer to an ordinary death, being immersed with a few friends in a cask of Madeira, until that time, then to be recalled to life by the solar warmth of my dear country! But... in all probability, we live in a century too little advanced, and too near the infancy of science, to see such an art brought in our time to its perfection...”

Thus the notion of human biological immortality through science and medicine is not as new as most of us are probably quick to presume. Men of stature and intellect, respected and admired historical figures, have been contemplating the prospect for hundreds of years at least.

Thirdly, I think that religion itself exemplifies our desire for indefinite lifespans. This may seem counter-intuitive considering that many criticisms of life-extension come from underlying religious arguments and worldviews – for instance that we shouldn’t be playing god, or messing with the way god created us. But the fact is that most religions have a conception of the afterlife – i.e. of eternal life following the physical death of the body. The fact that belief in an afterlife is a feature shared by almost all historical religions, that belief in an afterlife was conceived in a whole host of cultures independent of one another, shows that indefinite lifespans is one of humanity’s most deep-rooted and common longings and desires – indeed, one so deep-rooted that it transcends cultural distance and deep historical time.

3. The Selfishness Critique

Now I’d like to turn to the third Specter of Immortality – the criticism of selfishness. Whereas the first specter of immortality was a critique of the ethicacy of life-extension, this second specter is more a moralistic critique of the worthiness of actually spending one’s time trying further progress in the field today.

The view that life-extension researchers, activists and supporters are arrogant for thinking that we somehow deserve to live longer than those that came before us. As though we were trying to increase public support for and interest in life-extension merely for the sake of continuing our own lives. This too is I think a rather baseless criticism. Every life-extension researcher, activist, scholar and supporter I know does it not for the sake of their own lives but for the sake of the 100,000 people that die every day due to age-correlated causes. That’s right ladies and gentlemen, 100,000 people will die from aging today, lost forever to causes that are in principle preventable and ultimately unnecessary.

There are roughly 86,000 seconds in a day. That works out to a little more than one death per second. That’s about equal to the entire population of Washington DC dying every week; 3 million preventable deaths per month, and 36.5 million deaths per year. A group larger than the entire population of Canada will die from aging this year – and the fact that it sickens so few of us is incredibly sickening to me. This is an untenable situation for a civilization as capable as ours – we who have reshaped the world over, we who have gone to the moon, we who have manipulated atoms despite out fat monkey fingers.

Humanity is an incredibly powerful and unprecedented phenomena, and to say that we simply cannot do anything about death is to laugh in the face of history to some extent. Recall that very learned and esteemed men once said that heavier-than-air flying machines – and a great many other things we take for granted today – is impossible.

We cringe and cry when we hear of acts of genocide or horrible accidents killing thousands. But this occurs every day, on the toll of 100,000 deaths per day, right under our noses.

Doing something about this daily cataclysm is what drives my own work, and the work of most every life-extension supporter I know. The life-extension movement is about decreasing the amount of involuntary suffering in the world, and only lastly about our own, personal longevity, if at all. The eradication of involuntary death via science and medicine is nothing less than the humanitarian crisis of our times!

And again, this is something that I think each and every one of you can take part in. Become a life-extension supporter, advocate and activist. It may not only be the easiest way that you can contribute to hastening progress in the field of life-extension, but the most effective way as well. Thank you.

“I would consider two of the three critiques – namely the naturality critique and the selfishness critique – to be largely unfounded and vacuous; I don’t think they will be real worries when comprehensive life-extension therapies arrive.”

Absolutely, but the author ought to take the other critique head on.  In other words, the other critique is that we currently live in a Malthusian economy, where there are limited resources, and more people will mean more poverty.

Soon, thanks to exponential technology growth, we will transition to an abundance economy, where there will be virtually unlimited resources, and the thing that we will lack is enough people and particularly builders (i.e. I suggest reading the book Abundance for a more complete argument due to the space restrictions here).

I agree with the author that many many more people can be economically accommodated on Earth if we just get smart with design and infrastructure.  BUT, soon we will be routinely escaping the Earth’s gravity well, which means unlimited real estate, exponential production potential, and a very very large demand for settlers.

Furthermore, I would argue that technology is driven my about 5% of the population who are builders.  Those minds are almost irreplaceable, and to save them would mean a gigantic return on the resources necessary to save and support everyone.  Wish I could elaborate, but this is too long already.

“Soon, thanks to exponential technology growth, we will transition to an abundance economy, where there will be virtually unlimited resources, and the thing that we will lack is enough people and particularly builders (i.e. I suggest reading the book Abundance for a more complete argument due to the space restrictions here).”

Yes, but do we actually know that? I certainly agree there is reason to believe this could happen, but should we be assuming it necessarily will?

In any case it is good to keep getting into the minds of those who are opposed to or fearful of efforts to radically extend human life, and my natural inclination is to agree that the resource issue is the one critique that cannot be dismissed fairly quickly as “unfounded and vacuous”. However, in some respects I think this is because I am a natural born utilitarian, so notwithstanding my religious upbringing (or perhaps because of it?) I find it difficult to really engage with the “natural is good” fallacy or the idea that we should prioritise the rights of people who don’t yet even exist (i.e. “future generations”) with those of people who already do. I don’t mean by this that we shouldn’t care about future generations that we have reason to believe *will* exist, but an ethic that implies that we should allow them to exist, even if we have to die so that they can exist, seems to me to be taking the “ultimate sacrifice” idea unnecessarily far.

But again, this is arguing from within an essentially utilitarian perspective,  and this brings me back to my earlier point: it is essential, especially for those of us who think that indefinite life extension is worth fighting for, and are actively fighting for it, to enter the mindsets of those who don’t, even for reasons we find “unfounded and vacuous”. First we need to show that we have listened to and are capable, at least to some extent, of empathising with their point of view, before we can have any real hope of getting their engagement in a discussion that has some prospect of actually changing their minds.

Your characterization of the “selfishness critique” jousts at a straw man. I have seen people make the objection you attribute (that it’s all about personal life extension)—and it’s very far from a “vacuous” critique—but it’s quite distinct from the question of social justice. You’re conflating two arguments to create a false inconsistency.

The real “selfishness” objection is more typically that people involved in life extension _won’t admit_ that they’re in it to extend their own lives. As such, it’s unprovable—who can know another’s secret motives?—but if you could find evidence for it, it’s a really solid problem. After all, if you’re deluded about your motives, history is filled with abundant examples to argue you’re going to get bitten on the but for it.

The social justice critique is different. It’s not about altruism; it’s about fairness. THAT’s where the ‘why are you so special?’ question comes in, and it’s far from a vacuous question, especially when so many involved in life-extension treat it as a moral crusade. Sure, let’s “beat death”—but what are you going to do about the billions of people that you are going to be absolutely unable to help? And how can you be so certain of your ethical reasoning, which is going to have to justify mandating fundamental changes in human behavior across all societies in order to support a world without death?

Simple ‘transition to an abundance economy’ is a highly dubious outcome given the present course. If we do get to an abundance economy, it’s going to be through a process that involves several billion people dying or at the very least being extremely uncomfortable for a very long time.

If you could shift the world to a zero-death abundance economy tomorrow, you’d still have to change all the world’s cultures to accommodate the new reality. Given what we know about humans, that would take several generations in a best-case scenario, and put the vast majority of the living through hell in the meantime (most likely accompanied by cultural-resource wars of meta-epic proportion).

Dismissal of the resource arguments is really rather a strange tack to take, it seems to me. Dismissing the resource arguments basically requires that you first assume that we will transition to something like an abundance economy; but more importantly, it still assumes an essentially dominionist right to consume resources to suit ourselves. As a technological society we’ve traditionally assumed that, and have traditionally assumed that we’ll be able to deal with the consequences when they arise; again, appeal to historical evidence suggests that, to say the least, we haven’t always been right about that.

“Another contemporary solution paradigm we can leverage to help mitigate the detrimental effects of overpopulation on living-space is seasteading. This is the notion of creating permanent dwellings and structures at sea, essentially floating cities, outside of the territory of governments – more often than not to get around legal complications relating to whatever the prospective seasteaders wish to do. This movement is already bringing about designs and feasibility studies relating to the safe construction of very large floating cities.”

It would have been good to expand upon this, and as to what these legal complications, (tax), and who these potential seasteaders may be, (Lifeboat people?)

Is it really “feasible” and practicable to want of seasteads in “international waters” and outside the juristiction and protections of nation states?


You raise valid points. Are those that propose an “end to death” and it’s noble pursuit really concerned with egalitarianism?

Another issue is parallel to problems associated with aging populations in western countries today and the economic burdens upon pensions, whilst dealing with global debt, austerity and “race to the bottom”, increase and persistence of “wage servitude” political mentalities?

Are these people that have overcome death, (Rich and Poor alike), expected to be productive for eternity? What will they live on, (economically)? “The fat of the land”?

At what age does it not become viable or socially acceptable to be productive and to work? 60s, 70s, 80s.. surely not 90s?

Just because death has been “halted”, does not necessarily mean that youth will be restored, nor that healthcare costs will not increase exponentially?


The ‘selfishness’ critique comes across stronger when presented as in if life extensionists really cared about building better lives in general, why aren’t they more involved in accelerating the (relatively simple) technologies listed in that article?

Very good article.  Significant and increasing resources are being applied to AGI, and we need the same to go into life extension and brain preservation.  Not just because they are Very Good Things in their own right, but also because they will enable a smooth transition to uploading minds, if and when that becomes possible.

The best way to get major resources applied to life extension and brain preservation is to encourage popular demand, which means addressing the arguments the author raises.
