******************************
When asked what the biggest bottleneck for progress in life extension is, most thinkers and researchers say funding. Others say the biggest bottleneck is breakthroughs, while still others say it’s our way of approaching the problem (i.e., seeking healthy life extension, a.k.a. “aging gracefully”, instead of more comprehensive methods of radical life extension). But the majority seem to feel that the largest determining factor impacting how long it takes to achieve indefinite lifespans is adequate funding to plug away at developing and experimentally verifying the various alternative technologies and methodologies that have already been proposed (e.g. Robert Freitas’s Nanomedicine [1], Aubrey de Grey’s Strategies for Engineered Negligible Senescence [2, 3, 4], Michael R. Rose’s Evolutionary Longevity [5, 6]). I claim that Radical Longevity’s biggest bottleneck is not funding, but advocacy, activism and lobbying.
***

This is because the final objective of increased funding for Radical Longevity and Life Extension research can be more effectively and efficiently achieved through public advocacy for Radical Life Extension than it can by direct funding or direct research, per unit of time or effort. Research and development obviously still need to be done, but an increase in researchers needs an increase in funding, and an increase in funding needs an increase in the public perception of indefinite longevity’s feasibility and desirability.

There is no definitive timespan that it will take to achieve radically extended life. How long it takes to achieve Radical Longevity is determined by how hard we work at it and how much effort we put into it. More effort means that it will be achieved sooner. And by and large, an increase in effort can be best achieved by an increase in funding, and an increase in funding can be best achieved by an increase in public advocacy. You will likely accelerate the development of Radically Extended Life, per unit of time or effort, by advocating the desirability, ethicality, and technical feasibility of longer life than you will by doing direct research, or by working towards the objective of directly contributing funds to life-extension projects and research initiatives.

In order to get funding we need to demonstrate with explicit clarity just how much we want it, and that we can do so while minimizing potentially negative societal repercussions like overpopulation. We must do our best to vehemently invalidate the clichés that promulgate the sentiment that life extension is dangerous or unethical. It needn’t be either, and nor is it necessarily likely to be either.

Some think that spending one’s time deliberating the potential issues that could result from greatly increased lifespans and the ways in which we could mitigate or negate them won’t make a difference until greatly increased lifespans are actually achieved. I disagree. While any potentially negative repercussions of life extension (like overpopulation) aren’t going to happen until life extension is achieved, offering solution paradigms and ways in which we could negate or mitigate such negative repercussions decreases the time we have to wait for it by increasing the degree with which the wider public feels it to be desirable, and that it can very well be done safely and ethically. Those who are against radical life extension are against it either because they think it is infeasible (in which case being “against” it may be too strong a descriptor) or because they have qualms relating to its ethicality or its safety. More people openly advocating against it means a higher public perception of its undesirability. Whether indefinite longevity is eventually achieved via private industry or via government-subsidized research initiatives, we need to create the public perception that it is widely desired before either government or industry will take notice.

The sentiment that the best thing we can do is simply live healthily and wait until progress is made seems to be fairly common as well. People have the feeling that researchers are working on it, that it will happen if it can happen, and that waiting until progress is made is the best course to take. Such lethargy will not help Radical Longevity in any way. How long we have to wait for indefinite lifespans is a function of how much effort we put into it. And in this article I argue that how much funding and attention life extension receives is by and large a function of how widespread the public perception of its feasibility and desirability is.

This isn’t simply about our individual desires to live longer. It might be easier to hold the sentiment that we should just wait it out until it happens if we only consider its impact on the scale of our own individual lives. Such a sentiment may also be aided by the view that greatly longer lives would be a mere advantage, nice but unnecessary. I don’t think this is the case. I argue that the technological eradication of involuntary death is a moral imperative if there ever was one. If how long we have to wait until radical longevity is achieved depends on how vehemently we demand it and on how hard we work to create the public perception that longer life is widely longed-for, then to what extent are  100,000 lives lost potentially needlessly every day while we wait on our hands? One million people will die wasteful and involuntary deaths in the next 10 days. 36.5 million people will die this year from age-correlated causes of functional decline. This puts the charges of inethicality in a ghostly new light. If advocating the desirability, feasibility, and blatant ethicality of life extension can hasten its implementation by even a mere 10 days, then one million lives that would have otherwise been lost will have been saved by the efforts of life-extension advocates, researchers, and fiscal supporters. Seen in this way, working toward radical longevity may very well be the most ethical and selfless way you could spend your time, in terms of the number of lives saved and/or the amount of suffering prevented.

One of the most common and easy-to-raise concerns I come across in response to any effort to minimize the suffering of future beings is that there are enough problems to worry about right now. “Shouldn’t we be worrying about lessening starvation in underdeveloped countries first? They’re starving right now. Shouldn’t we be focusing on the problems of today, on things that we can have a direct impact on?” Indeed. 100,000 people will die, potentially needlessly, tomorrow. The massive number of people that suffer involuntary death is a problem of today! Indeed, it may very well be the most pressing problem of today! What other source of contemporary suffering claims so many lives, and occurs on such a massive scale? What other “problem of today” is responsible for the needless and irreversible involuntary death of one hundred thousand lives per day? Certainly not starvation, or war, or cancer, all of which in themselves represent smaller sources of involuntary death. Longevity advocates do what they do for the same reason that people who try to mitigate starvation, war, and cancer do what they do, namely to lessen the amount of involuntary death that occurs.

This is a contemporary problem that we can have a direct impact on. People intuitively assume that we won’t achieve radically extended life until far in the future. This makes them conflate any lives saved by radically extended lifespans with lives yet to come into existence. This makes them see involuntary death as a problem of the future, rather than a problem of today. But more people than I’ve ever known will die tomorrow, from causes that are physically possible to obviate and ameliorate – indeed, from causes that we have potential and conceptual solutions for today.

I have attempted to show in this article that advocating life-extension should be considered as “working toward it” to as great an extent as directly funding it or performing direct research on it is considered as “working toward it”. Advocacy has greater potential to increase life extension’s widespread desirability than direct work or funding does, and increasing both its desirability and the public perception if its desirability has more potential to generate increased funding and research-attention for life-extension than direct funding or research does. Advocacy thus has the potential to contribute to the arrival of life extension and hasten its implementation just as much, if not more so (as I have attempted to argue in this article), than practical research or direct funding does. This should motivate people to help create the momentous momentum we need to really get the ball rolling. To be a longevity advocate is to be a longevity worker! Involuntary death from age-associated, physically-remediable causes is the largest source of death, destruction and suffering today.  Don’t you want to help prevent the most widespread source of death and of suffering in existence today? Don’t you want to help mitigate the most pressing moral concern not only of today, but of the entirety of human history – namely physically remediable involuntary death?

Then advocate the technological eradication of involuntary death. Advocate the technical feasibility, extreme desirability, and blatant ethicality of radically extending life. Death is a cataclysm. We need not sanctify the seemingly inevitable any longer. We need not tell ourselves that death is somehow a good thing, or something we can do nothing about, in order to live with the “fact” of it any longer. Soon it won’t be a fact of life. Soon it will be an artifact of history. Life may not be ipso facto valuable according to all philosophies of value – but life is a necessary precondition for any sort of value whatsoever. Death is dumb, dummy! An incontrovertible waste convertible into nothing! A negative-sum blight! So if you want to contribute to the solution of problems of today, if you want to help your fellow man today, then stand proud and shout loud “Doom to Arbitrary Duty and Death to  Arbitrary Death!” at every crowd cowed by the seeming necessity of death.

Transhumanism, Technology, and Science: To Say It’s Impossible Is to Mock History Itself – Article by Franco Cortese

Transhumanism, Technology, and Science: To Say It’s Impossible Is to Mock History Itself – Article by Franco Cortese

******************************
One of the most common arguments made against Transhumanism, Technoprogressivism, and the transformative potentials of emerging, converging, disruptive and transformative technologies may also be the weakest: technical infeasibility. While some thinkers attack the veracity of Transhumanist claims on moral grounds, arguing that we are committing a transgression against human dignity (in turn often based on ontological grounds of a static human nature that shan’t be tampered with) or on grounds of safety, arguing that humanity isn’t responsible enough to wield such technologies without unleashing their destructive capabilities, these categories of counter-argument (efficacy and safety, respectively) are more often than not made by people somewhat more familiar with the community and its common points of rhetoric.
***
In other words these are the real salient and significant problems needing to be addressed by Transhumanist and Technoprogressive communities. The good news is that the ones making the most progress in terms of deliberating the possible repercussions of emerging technologies are Transhumanist and Technoprogressive communities. The large majority of thinkers and theoreticians working on Existential Risk and Global Catastrophic Risk, like The Future of Humanity Institute and the Lifeboat Foundation, share Technoprogressive inclinations. Meanwhile, the largest proponents of the need to ensure wide availability of enhancement technologies, as well as the need for provision of personhood rights to non-biologically-substrated persons, are found amidst the ranks of Technoprogressive Think Tanks like the IEET.
***

A more frequent Anti-Transhumanist and Anti-Technoprogressive counter-argument, by contrast, and one most often launched by people approaching Transhumanist and Technoprogressive communities from the outside, with little familiarity with their common points of rhetoric, is the claim of technical infeasibility based upon little more than sheer incredulity.

Sometimes a concept or notion simply seems too unprecedented to be possible. But it’s just too easy for us to get stuck in a spacetime rut along the continuum of culture and feel that if something were possible, it would have either already happened or would be in the final stages of completion today. “If something is possible, when why hasn’t anyone done it Shouldn’t the fact that it has yet to be accomplished indicate that it isn’t possible?” This conflates ought with is (which Hume showed us is a fallacy) and ought with can. Ought is not necessarily correlative with either. At the risk of saying the laughably-obvious, something must occur at some point in order for it to occur at all. The Moon landing happened in 1969 because it happened in 1969, and to have argued in 1968 that it simply wasn’t possible solely because it had never been done before would not have been  a valid argument for its technical infeasibility.

If history has shown us anything, it has shown us that history is a fantastically poor indicator of what will and will not become feasible in the future. Statistically speaking, it seems as though the majority of things that were said to be impossible to implement via technology have nonetheless come into being. Likewise, it seems as though the majority of feats it was said to be possible to facilitate via technology have also come into being. The ability to possiblize the seemingly impossible via technological and methodological in(ter)vention has been exemplified throughout the course of human history so prominently that we might as well consider it a statistical law.

We can feel the sheer fallibility of the infeasibility-from-incredulity argument intuitively when we consider how credible it would have seemed a mere 100 years ago to claim that we would soon be able to send sentences into the air, to be routed to a device in your pocket (and only your pocket, not the device in the pocket of the person sitting right beside you). How likely would it have seemed 200 years ago if you claimed that 200 years hence it would be possible to sit comfortably and quietly in a chair in the sky, inside a large tube of metal that fails to fall fatally to the ground?

Simply look around you. An idiosyncratic genus of great ape did this! Consider how remarkably absurd it would seem for the gorilla genus to have coordinated their efforts to build skyscrapers; to engineer devices that took them to the Moon; to be able to send a warning or mating call to the other side of the earth in less time than such a call could actually be made via physical vocal cords. We live in a world of artificial wonder, and act as though it were the most mundane thing in the world. But considered in terms of geological time, the unprecedented feat of culture and artificial artifact just happened. We are still in the fledging infancy of the future, which only began when we began making it ourselves.
***

We have no reason whatsoever to doubt the eventual technological feasibility of anything, really, when we consider all the things that were said to be impossible yet happened, all the things that were said to be possible and did happen, and all the things that were unforeseen completely yet happened nonetheless. In light of history, it seems more likely than a given thing would eventually be possible via technology than that it wouldn’t ever be possible. I fully appreciate the grandeur of this claim – but I stand by it nonetheless. To claim that a given ability will probably not be eventually possible to implement via technology is to laugh in the face of history to some extent.

The main exceptions to this claim are abilities wherein you limit or specify the route of implementation. Thus it probably would not be eventually possible to, say, infer the states of all the atoms comprising the Eifel Tower from the state of a single atom in your fingernail: categories of ability where you specify the implementation as the end-ability – as in the case above, the end ability was to infer the state of all the atoms in the Eifel Tower from the state of a single atom.

These exceptions also serve to illustrate the paramount feature allowing technology to possiblize the seemingly improbable: novel means of implementation. Very often there is a bottleneck in the current system we use to accomplish something that limits the scope of tis abilities and prevents certain objectives from being facilitated by it. In such cases a whole new paradigm of approach is what moves progress forward to realizing that objective. If the goal is the reversal and indefinite remediation of the causes and sources of aging, the paradigms of medicine available at the turn of the 20th century would have seemed to be unable to accomplish such a feat.

The new paradigm of biotechnology and genetic engineering was needed to formulate a scientifically plausible route to the reversal of aging-correlated molecular damage – a paradigm somewhat non-inherent in the medical paradigms and practices common at the turn of the 20th Century. It is the notion of a new route to implementation, a wholly novel way of making the changes that could lead to a given desired objective, that constitutes the real ability-actualizing capacity of technology – and one that such cases of specified implementation fail to take account of.

One might think that there are other clear exceptions to this as well: devices or abilities that contradict the laws of physics as we currently understand them – e.g., perpetual-motion machines. Yet even here we see many historical antecedents exemplifying our short-sighted foresight in regard to “the laws of physics”. Our understanding of the physical “laws” of the universe undergo massive upheaval from generation to generation. Thomas Kuhn’s The Structure of Scientific Revolutions challenged the predominant view that scientific progress occurred by accumulated development and discovery when he argued that scientific progress is instead driven by the rise of new conceptual paradigms categorically dissimilar to those that preceded it (Kuhn, 1962), and which then define the new predominant directions in research, development, and discovery in almost all areas of scientific discovery and conceptualization.

Kuhn’s insight can be seen to be paralleled by the recent rise in popularity of Singularitarianism, which today seems to have lost its strict association with I.J. Good‘s posited type of intelligence explosion created via recursively self-modifying strong AI, and now seems to encompass any vision of a profound transformation of humanity or society through technological growth, and the introduction of truly disruptive emerging and converging (e.g., NBIC) technologies.

This epistemic paradigm holds that the future is less determined by the smooth progression of existing trends and more by the massive impact of specific technologies and occurrences – the revolution of innovation. Kurzweil’s own version of Singularitarianism (Kurzweil, 2005) uses the systemic progression of trends in order to predict a state of affairs created by the convergence of such trends, wherein the predictable progression of trends points to their own destruction in a sense, as the trends culminate in our inability to predict past that point. We can predict that there are factors that will significantly impede our predictive ability thereafter. Kurzweil’s and Kuhn’s thinking are also paralleled by Buckminster Fuller in his notion of ephemeralization (i.e., doing more with less), the post-industrial information economies and socioeconomic paradigms described by Alvin Toffler (Toffler, 1970), John Naisbitt (Naisbitt 1982), and Daniel Bell (Bell, 1973), among others.

It can also partly be seen to be inherent in almost all formulations of technological determinism, especially variants of what I call reciprocal technological determinism (not simply that technology determines or largely constitutes the determining factors of societal states of affairs, not simply that tech affects culture, but rather than culture affects technology which then affects culture which then affects technology) a là Marshall McLuhan (McLuhan, 1964) . This broad epistemic paradigm, wherein the state of progress is more determined by small but radically disruptive changes, innovation, and deviations rather than the continuation or convergence of smooth and slow-changing trends, can be seen to be inherent in variants of technological determinism because technology is ipso facto (or by its very defining attributes) categorically new and paradigmically disruptive, and if culture is affected significantly by technology, then it is also affected by punctuated instances of unintended radical innovation untended by trends.

That being said, as Kurzweil has noted, a given technological paradigm “grows out of” the paradigm preceding it, and so the extents and conditions of a given paradigm will to some extent determine the conditions and allowances of the next paradigm. But that is not to say that they are predictable; they may be inherent while still remaining non-apparent. After all, the increasing trend of mechanical components’ increasing miniaturization could be seen hundreds of years ago (e.g., Babbage knew that the mechanical precision available via the manufacturing paradigms of his time would impede his ability in realizing his Baggage Engine, but that its implementation would one day be possible by the trend of increasingly precise manufacturing standards), but the fact that it could continue to culminate in the ephemeralization of Bucky Fuller (Fuller, 1976) or the mechanosynthesis of K. Eric Drexler (Drexler, 1986).

Moreover, the types of occurrence allowed by a given scientific or methodological paradigm seem at least intuitively to expand, rather than contract, as we move forward through history. This can be seen lucidly in the rise of Quantum Physics in the early 20th Century, which delivered such conceptual affronts to our intuitive notions of the possible as non-locality (i.e., quantum entanglement – and with it quantum information teleportation and even quantum energy teleportation, or in other words faster-than-light causal correlation between spatially separated physical entities), Einstein’s theory of relativity (which implied such counter-intuitive notions as measurement of quantities being relative to the velocity of the observer, e.g., the passing of time as measured by clocks will be different in space than on earth), and the hidden-variable theory of David Bohm (which implied such notions as the velocity of any one particle being determined by the configuration of the entire universe). These notions belligerently contradict what we feel intuitively to be possible. Here we have claims that such strange abilities as informational and energetic teleportation, faster-than-light causality (or at least faster-than-light correlation of physical and/or informational states) and spacetime dilation are natural, non-technological properties and abilities of the physical universe.

Technology is Man’s foremost mediator of change; it is by and large through the use of technology that we expand the parameters of the possible. This is why the fact that these seemingly fantastic feats were claimed to be possible “naturally”, without technological implementation or mediation, is so significant. The notion that they are possible without technology makes them all the more fantastical and intuitively improbable.

We also sometimes forget the even more fantastic claims of what can be done through the use of technology, such as stellar engineering and mega-scale engineering, made by some of big names in science. There is the Dyson Sphere of Freeman Dyson, which details a technological method of harnessing potentially the entire energetic output of a star (Dyson,  1960). One can also find speculation made by Dyson concerning the ability for “life and communication [to] continue for ever, using a finite store of energy” in an open universe by utilizing smaller and smaller amounts of energy to power slower and slower computationally emulated instances of thought (Dyson, 1979).

There is the Tipler Cylinder (also called the Tipler Time Machine) of Frank J. Tipler, which described a dense cylinder of infinite length rotating about its longitudinal axis to create closed timelike curves (Tipler, 1974). While Tipler speculated that a cylinder of finite length could produce the same effect if rotated fast enough, he didn’t provide a mathematical solution for this second claim. There is also speculation by Tipler on the ability to utilize energy harnessed from gravitational shear created by the forced collapse of the universe at different rates and different directions, which he argues would allow the universe’s computational capacity to diverge to infinity, essentially providing computationally emulated humans and civilizations the ability to run for an infinite duration of subjective time (Tipler, 1986, 1997).

We see such feats of technological grandeur paralleled by Kurt Gödel, who produced an exact solution to the Einstein field equations that describes a cosmological model of a rotating universe (Gödel, 1949). While cosmological evidence (e.g., suggesting that our universe is not a rotating one) indicates that his solution doesn’t describe the universe we live in, it nonetheless constitutes a hypothetically possible cosmology in which time-travel (again, via a closed timelike curve) is possible. And because closed timelike curves seem to require large amounts of acceleration – i.e. amounts not attainable without the use of technology – Gödel’s case constitutes a hypothetical cosmological model allowing for technological time-travel (which might be non-obvious, since Gödel’s case doesn’t involve such technological feats as a rotating cylinder of infinite length, rather being a result derived from specific physical and cosmological – i.e., non-technological – constants and properties).

These are large claims made by large names in science (i.e., people who do not make claims frivolously, and in most cases require quantitative indications of their possibility, often in the form of mathematical solutions, as in the cases mentioned above) and all of which are made possible solely through the use of technology. Such technological feats as the computational emulation of the human nervous system and the technological eradication of involuntary death pale in comparison to the sheer grandeur of the claims and conceptualizations outlined above.

We live in a very strange universe, which is easy to forget midst our feigned mundanity. We have no excuse to express incredulity at Transhumanist and Technoprogressive conceptualizations considering how stoically we accept such notions as the existence of sentient matter (i.e., biological intelligence) or the ability of a genus of great ape to stand on extraterrestrial land.

Thus, one of the most common counter-arguments launched at many Transhumanist and Technoprogressive claims and conceptualizations – namely, technical infeasibility based upon nothing more than incredulity and/or the lack of a definitive historical precedent – is one of the most baseless counter-arguments as well. It would be far more credible to argue for the technical infeasibility of a given endeavor within a certain time-frame. Not only do we have little, if any, indication that a given ability or endeavor will fail to eventually become realizable via technology given enough development-time, but we even have historical indication of the very antithesis of this claim, in the form of the many, many instances in which a given endeavor or feat was said to be impossible, only to be realized via technological mediation thereafter.

It is high time we accepted the fallibility of base incredulity and the infeasibility of the technical-infeasibility argument. I remain stoically incredulous at the audacity of fundamental incredulity, for nothing should be incredulous to man, who makes his own credibility in any case, and who is most at home in the necessary superfluous.
