Immortality and Overpopulation

As I'm sure you've noticed Hollywood's latest crop of upcoming poorly thought out films includes "In Time", a film where people no longer age but to prevent overpopulation they are only allowed to live so long and use their remaining time as currency. There are so many ways that could not work.

For one thing, that system would require a lot of new births to prevent deflation as time is depleted, kind of contradictory to the intended purpose. But that's beside the point, there are far less controversial ways to regulate immortal populations.

The simplest one would be to surgically sterilize anyone who becomes immortal. Considering how radical such a procedure would be it should be trivial to add in a vasectomy or tubal ligation. That simple act would discourage many groups from becoming ageless in the first place, unfortunately those same people are the same ones largely responsible for the planet's high population growth in recent decades. Still, the lure of eternal youth is sure to snare a majority of the populace over the centuries.

And if you're concerned about a slow extinction from attrition as no one has kids, don't be. If there's room for more people the government can allow some people to reproduce using stored sperm and ova or as a last resort, cloning.

Still, those measures are most likely not enough, fortunately the technologies to construct habitats in space or the ocean seem to be more feasible than completely halting aging. Thus making more room for our growing population before we have to deal with such a crisis. Though somewhat limited life-extension is probably more doable than transporting a significant proportion of the population out of earth's gravity well.

Brain Uploading, Not Just For Immortality

If you have read my previous posts on this blog you might recall my opinion that most ways of creating a full brain emulation would not result in immortality for the original, but Roko Mijic's talk on FAI made me think about how uploading may benefit humanity in other ways. Roko mentions and even recommends using brain emulations as a stepping stone towards benevolent superintelligence, but there might be less fantastical uses for the technology if it is developed before the Singularity drives humanity into extinction.

The appeal of using brain emulations for AI is obvious, with an AI made from scratch you don't really know what to expect. Whereas an emulation theoretically gives you something with motivations you understand, or at least an easy way to teach an AI human values. Also you can easily monitor every process of an emulation, which is where I got my idea.

There are many mysteries still locked within the human mind and even if decent mind reading technology is developed it would be difficult for one to provide data on everyday activities with a brain scanner around their head. That is where uploading comes in, remember, you don't necessarily need to understand how something works to copy it. No doubt there are many psychologists who would love to pick around in someone's head to the extent that only an emulation could provide. Not to mention that an emulation of a psychopath or schizophrenic would help AI programmers recognize what not to do.

A possibility on the future

Imagine, that technology has advanced to the point where a complete copy of your personality and memories can be made through a process as simple as an MRI is today. And that two or more people with the appropriate implants can perceive through each other's senses and "hear" each other's thoughts, to the point where it can be difficult to distinguish whose thoughts and experiences are whose. Now imagine that you have those implants and that you have an AI copy of yourself made. Once your copy is activated your implants are linked to it, the copy doesn't have a chance to form an independent thought and essentially becomes an extension of your own mind. You become much better at multi-tasking as now you essentially have two brains, you can battle orcs while you're in a meeting with your boss. You can use one brain to work while your other is on vacation. Maybe you have an android that your AI self can teleoperate if you ever need to be in two places at once. But then one day you feel a sudden flash of pain and all sensory input from your biological body cuts out, frantically you check all your life signs. Pulse: zero; brain activity: flat-lined; you come to one conclusion, you are dead.

The difference between Nietzsche and Transhumanism

On a few occasions Friedrich Nietzsche's concept of the Uebermensch (over-human) has been mistakenly identified with the Transhumanist concept of the Posthuman. This mistake largely stems from the following quote from Thus Spoke Zarathustra: "All beings so far have created something beyond themselves; and do you want to be the ebb of this great flood and even go back to the beasts rather than overcome man? What is the ape to man? A laughingstock or a painful embarrassment. And man shall be just that for the overman: a laughingstock or a painful embarrassment…" While Posthumans could be described as being as far beyond humans as humans are beyond apes or even insects, most transhumanists do not hold the same values as Nietzsche did, in fact many of them seem to prefer something closer to the Last Man than the Uebermensch. The Last Man in Nietzschean philosophy was what Nietzsche believed that European society was currently headed towards instead of the Uebermensch, the Last Man is a weak-willed individual who is tired of life, takes no risks, and seeks only comfort and security, instead of developing new values he embraces nihilism. Whereas the Uebermensch would be almost the exact opposite, one who lives life to the fullest and develops new values to fill the void left by the death of god. Many transhumanists seek a post-scarcity society (no need to work) where people can live as long as they want (free of risks, may result in one getting bored with life). In addition, Singulatarianism is almost a religion, promising escape from this world through the rapture of the singularity, and relief from the suffering of mortal existence by uploading. Those who have been reading here know Nietzsche's attitude on suffering, what you probably don't know is that one of his problems with religion was its denigration of human existence and otherworldliness, which some currents of transhumanism have taken on. This is overall, why I no longer call myself a transhumanist, I have found too many of them to be hopeless idealists or deluded new agers. It probably goes without saying that I would find the Uebermensch a much more preferable future than a post-scarcity society full of Last Men or a relapse into Christo-Buddhist thinking hiding behind the guise of science.

Five Ways to Live Forever

Physical immortality is a common goal of many futurists and transhumanists, for that reason I've written a list of probable ways for one to live at least a very long time.

1. Anti-aging midication: The use of advanced medicine to stave off the effects of aging by rejuvenating mitochondria and lengthening telomeres, as well as reducing wrinkles and holding senility at bay. Would involve the least changes of any of the techniques on this list, but would not be viable over the long term as there are many different effects of aging and the human brain only has enough memory for a couple centuries of experiences at most. Also, it's likely that someone using this form of longevity would require organ transplants every few years.

2. Genetic immortality: Using genetic engineering to design a person born with the effects of anti-aging drugs, unfortunately this is unlikely to happen any time soon and would require a near complete re-design of the human body. In addition making an already fully-developed person immortal this way would require highly advanced nanotechnology, which brings us to the next option.

3. Rejuvenation: Periodically using stem cells and/or nanomachines to repair damage caused by aging and "reset" one's cellular clocks and effectively make them decades younger. May also include memory alteration, one could selectively "delete" certain memories in order to make room for new ones and only keep particularly notable ones.

4. Cyborgization: This method could range from simply hosting permanent nanomachine symbiont's to continuously repair and rejuvenate the body, to replacing almost all of one's biological body with mechanical parts. Machines are noticeably easier to repair than biological systems, and can also increase the amount of physical memory available to a person, eventually as even the brain is replaced this could cross over into Uploading.

5. Mind Uploading: In this option, as I stated in my August 17th post, the data contained in a person's brain is copied onto a different substrate. This does pose some existential problems but if you do accept that the copy is the same person as the original then uploading is the best way to achieve immortality. The other options don't make the person immune to accidents or murder, while a backup copy could be easily made as insurance against those situations. Heck, one could have an implant in their head that could transmit their consciousness to a cloning facility at the exact moment of death and be downloaded into a new body.
