Dedication to healthy foods considered an eating disorder

It almost sounds like the headline from an Onion article.

But back in August of 2009 the Guardian published a piece about how a fixation with healthy eating can be a sign of a serious psychological disorder. Called orthorexia nervosa, this so-called 'condition' was first diagnosed by Californian Steven Bratmanin in 1997 and is described as a "fixation on righteous eating." According to Bratmanin,

Orthorexics commonly have rigid rules around eating. Refusing to touch sugar, salt, caffeine, alcohol, wheat, gluten, yeast, soya, corn and dairy foods is just the start of their diet restrictions. Any foods that have come into contact with pesticides, herbicides or contain artificial additives are also out.

This obsession about which foods are "good" and which are "bad" means orthorexics can end up malnourished, claim the researchers, but at the same time be overweight or look normal. They are solely concerned with the quality of the food they put in their bodies, refining and restricting their diets according to their personal understanding of which foods are truly 'pure'.

The most susceptible are middle-class, well-educated people who regularly read about food "scares" and have the time and money to source what they believe to be purer alternatives.

I could go on but I'm going to stop right there; you get the picture.

Wow, I'm flabbergasted by this. While I admit it possible that a very small minority of health conscious people may actually be starving themselves on account of food paranoia, I have to think it's exceptionally rare. But according to this article and the researchers cited, orthorexia nervosa is a pervasive problem. In fact, there is a quote in the article from Deanne Jade, founder of the National Centre for Eating Disorders, who said, "There is a fine line between people who think they are taking care of themselves by manipulating their diet and those who have orthorexia. I see people around me who have no idea they have this disorder. I see it in my practice and I see it among my friends and colleagues."

Okay, so there's an abundance of well-educated, informed, middle-class health nuts.

And their dedication to eating healthily is now considered an eating disorder.

Specifically, those people who have eliminated such things as sugar, salt, caffeine, alcohol, wheat, gluten, yeast, soya, corn and dairy foods from their diets—not to mention pesticides, herbicides, and artificial additives.

These people have an eating disorder?

I hardly think so. These people are my heros for goodness sake. While I can understand why some people might consider them obsessives, I think of them as focused and disciplined. Eliminating those particular foods along with those extraneous toxins should be considered a good thing.

But therein lies the problem. These researchers, some of whom should know better (particularly the dietitians), are much like society in general: completely ignorant of what constitutes a healthy diet. By consequence, any deviation from the status quo—in this case an apparent radically restrictive diet—is considered not just deviant behavior, but something that's actually pathological in nature.

Truth is, the vast majority of "food" out there is stuff we shouldn't be eating in the first place; the core of the modern grocery store is a nothing more than a crap dispenser. By consequence, the world's eating habits are insane. But some people are getting wise to it, adopting such diets as Paleo, Zone, and others. Yes, these diets can be quite restrictive in the types and quantities of foods involved, but that's the reality of healthy (and dare I say ethical) eating.

As a result, for those unaccustomed or unfamiliar with what a truly healthy diet looks like, it may look rather spartan. If not completely bonkers.

The food industry is partly to blame. Hyper-processed and fast foods laden in sugar and salt are a staple of many diets. Ad campaigns fool consumers into thinking they're eating healthily. Parents are regularly deceived into thinking that a bowl of super-sweetened cereal is an integral part of their children's well-balanced diet—and just because it has a bit of fibre in it.

The government is also partly responsible with their ridiculously inaccurate food pyramid. This is a particularly nefarious and longstanding turd of misinformation (or deliberate disinformation?) that informs the food industry and a myriad of other institutions about what and how much they're supposed to prepare and serve to the public.

Lastly, the general population is also to blame. Like the cigarette smoker, most people knowingly engage in habits that are bad for them, while many others insist on remaining ignorant.

So, here in the developed world where there are pandemics of diabetes, obesity, heart disease, metabolic syndrome and many, many other lifestyle related diseases, we are now being told that a dedication to prevention is a psychological disorder. What foolishness. This is irresponsible to the point of negligence.

The phrase 'my body is a temple' comes to mind. For many of us, our ongoing efforts to keep our minds and bodies healthy is an integral part of our daily lives. We know that proper habits will impact on our health both in the short and long term. By making careful food choices now and having the discipline to avoid unhealthy eating, we stand a much better chance of extending our healthy life-span and quality of life. There is nothing wrong with that.

In fact, if only more people had this so-called 'orthorexia nervosa' we'd all be in a much better place.


Interviewed by The Mark

I was recently interviewed by The Mark for a show about the future of humans. You can listen to the broadcast here. Episode description:

The first axiom of the Transhumanist Declaration is that: “Humanity stands to be profoundly affected by science and technology in the future. We envision the possibility of broadening human potential by overcoming aging, cognitive shortcomings, involuntary suffering, and our confinement to planet Earth.” The declaration is a missive that attempts to lay the social, political, and philosophical groundwork for the inevitable incorporation of technology into human biology.

If you think this sounds far-fetched, just consider the exponential scientific advances we've seen in the last 50 years. Travelling to the moon? Neil Armstrong did that in 1969. Cloning? Dolly the Sheep made headlines for it in 1996. Mapping the human genome? No problem, we finished in 2003. Science fiction is now science fact. You can read about it on the smartphone in your pocket that taps into that collection of humanity's knowledge called the internet.

So what's next for humans in this brave new world? Is this the next leap in human evolution? Or will adding technology cause us to lose a piece of our humanity?

This week on the show, host Chris Mitchell talks with three experts who speculate on what's coming next, and what we can do to prepare for it.

First up, a conversation with transhumanist George Dvorsky on what developments we can expect to see in the coming decades.

Next, Ian Kerr explains how medical technology could eventually erase human limitations.

Finally, Christopher Dewdney on why Michael Jackson was a pioneer of transhumanism.


Toth-Fejel: The politics and ethics of the weather machine

A tiny portion of a Hall Weather Machine
at 90,000 ft. This density may be
able to ameliorate global warming/cooling,
but would not be able to control weather.

A number of years ago, nanotechnology theorist J. Storrs Hall concieved of what is now called the Hall Weather Machine. It's exactly what it sounds like, an advanced system for controlling the weather:

The Hall Weather Machine is a thin global cloud consisting of small transparent balloons that can be thought of as a programmable and reversible greenhouse gas because it shades or reflects the amount of sunlight that hits the upper stratosphere. These balloons are each between a millimeter and a centimeter in diameter, made of a few-nanometer thick diamondoid membrane. Each balloon is filled with hydrogen to enable it to float at an altitude of 60,000 to 100,000 feet, high above the clouds. It is bisected by an adjustable sheet, and also includes solar cells, a small computer, a GPS receiver to keep track of its location, and an actuator to occasionally (and relatively slowly) move the bisecting membrane between vertical and horizontal orientations. Just like with a regular high-altitude balloon, the heavier control and energy storage systems would be on the bottom of the balloon to automatically set the vertical axis without requiring any energy. The balloon would also have a water vapor/hydrogen generator system for altitude control, giving it the same directional navigation properties that an ordinary hot-air balloon has when it changes altitudes to take advantage of different wind directions at different altitudes.

What's particularly impressive about the weather machine is that controlling a tenth of one percent of solar radiation is enough to force global climate in any direction we want. One percent is enough to change regional climate, and ten percent is enough for serious weather control.

The implications to remedial ecology, geoengineering, and technogaianism in general are profound, to say the least.

But as research engineer, and friend to the transhumanists, Tihamer Toth-Fejel notes in his article, "The Politics and Ethics of the Hall Weather Machine," managing the social and environmental implications of such a control system could prove to be tricky, if not completely untenable.

The weather machine could prove to be a disaster, either through misuse, abuse, or just plain ignorance.

For example, the global coordination of the reflective weather machine would allow for the bouncing of concentrated solar energy around the globe, making it possible to set cities on fire—the type of fire caused by dropping a nuclear bomb per second for as long as desired. As Toth-Fejel notes, "the potential for abuse is rather large." The temptation to weaponize such a device may be overwhelming. The whole project could start various arms races, including efforts to bring the entire system down.

In the article, Toth-Fejel considers a number of other scenarios and possible implications, both good and bad. Having a weather machine in place introduces a slew of fascinating implications, ranging from the environmental to the political. Toth-Fejel offers no easy answers or trite solutions, and instead uses the article the raise awareness about this important possibility.

Notaro: Why do we believe what we believe?

I love the intersection of psychology, rationality and memetics: "Why do we believe what we believe" by the IEET's Kris Notaro:

One can make the argument that people accept certain memes over others mainly because of what they are taught they will get out of believing them. If we apply instrumental conditioning (similar to classical conditioning) where we replace behavior with belief, the consequence would be, for example, that belief in god leads to eternal life in heaven. Or we can make the claim that “god experiences” lead to a warm feeling in the “heart and minds” of those who believe God is there for them. Therefore, they believe and act accordingly to what the meme’s reward is: eternal life and/or a good feeling.

In a conversation I had recently with a professor of psychology, we both agreed that a modification of the Critical Period concept is probably the primary reason why people in today’s culture believe in God. This would entail that the critical period for people to take on a belief in God would extend to adolescents and young adults. I personally started to question the existence of God in middle school where Prof. A. started to question her faith during high school. We are both agnostic/atheist primarily because of these experiences early in our brain development. We both accept modern paradigms of science over religion.

Neuroscience has shown that specific brain regions, synoptic bonds, and neurotransmitters influence people to believe one concept over another. Philosophy , sociology, and psychology demonstrate how people can take on certain beliefs because of critical periods of learning, choice (Doxastic Voluntarism), cooperation, and instrumental conditioning. Each of these pressures on the brain can lead to the propagation of concepts/memes. There are no definitive schemes which explain why be believe what we believe as a society, culture, and world. However I would argue that in the healthy brain that all these reasons are interconnected, from brain regions, to simplistic mythical stories.

Stuxnet worm allows hackers to control industrial machinery

Well, it finally happened: A worm has been developed that can break into computers which control machinery at the heart of industry. Such a security breach could allow attackers to assume control of critical systems like pumps, motors, alarms and valves in an industrial plant. Worse, safety systems could be switched off at a nuclear power plant; fresh water contaminated with effluent at a sewage treatment plant, or the valves in an oil pipeline opened, contaminating the land or sea.

The worm is called Stuxnet and it's about 600-kilobytes in size. It was professionally written, an indication that a nation-state or organized crime outfit is likely behind it.

This worm will prove particularly problematic for legacy systems, but it's also a wake-up call for new distributed systems such as smart grids. Security will have to be embedded in the architecture right from the start to avoid such vulnerabilities.

Mazlan Othman: United Nations ambassador to extraterrestrials

ADDENDUM: This story is bullshit. Dammit, I had I feeling....

Breaking news in the fast-paced world of exopolitics: The United Nations has appointed an obscure Malaysian astrophysicist, Mazlan Othman, to act as Earth's primary-point-of-contact for visiting extraterrestrials. Othman will head the UN's little-known Office for Outer Space Affairs (Unoosa).

The recent discovery of hundreds of planets around other stars has made the detection of alien life more likely than ever before; the UN feels that it must be ready to coordinate humanity’s response to any first contact. During a recent talk, Othman noted, "The continued search for extraterrestrial communication, by several entities, sustains the hope that some day humankind will receive signals from extraterrestrials. When we do, we should have in place a coordinated response that takes into account all the sensitivities related to the subject. The UN is a ready-made mechanism for such coordination."

Professor Richard Crowther, an expert in space law and governance at the UK Space Agency and who leads British delegations to the UN on such matters, noted that Othman is now the nearest thing we have to a 'take me to your leader' person.

In my opinion, the first order of business for Othman should be a screening of Mars Attacks to learn what not to do during first contact:

Boyden: Helping brains and machines work together

Credit: Technology Review

Neuroscientist Edward Boyden, in his article, "Brain Coprocessors," says we need to develop operating systems to help brains and machines work together.

Boyden notes that over the past 20 years there has been a slew of technologies that have enabled the observation or perturbation of information in the brain.

Take functional MRI, for example, which measures blood flow changes associated with brain activity. FMRI technology is being explored for purposes as diverse as lie detection, prediction of human decision making, and assessment of language recovery after stroke.

And implanted electrical stimulators, which enable control of neural circuit activity, are borne by hundreds of thousands of people to treat conditions such as deafness, Parkinson's disease, and obsessive-compulsive disorder. In addition, new methods, such as the use of light to activate or silence specific neurons in the brain, are being widely utilized by researchers to reveal insights into how to control neural circuits to achieve therapeutically useful changes in brain dynamics. "We are entering a neurotechnology renaissance," says Boyden, "in which the toolbox for understanding the brain and engineering its functions is expanding in both scope and power at an unprecedented rate."

He continues:

This toolbox has grown to the point where the strategic utilization of multiple neurotechnologies in conjunction with one another, as a system, may yield fundamental new capabilities, both scientific and clinical, beyond what they can offer alone. For example, consider a system that reads out activity from a brain circuit, computes a strategy for controlling the circuit so it enters a desired state or performs a specific computation, and then delivers information into the brain to achieve this control strategy. Such a system would enable brain computations to be guided by predefined goals set by the patient or clinician, or adaptively steered in response to the circumstances of the patient's environment or the instantaneous state of the patient's brain.

Some examples of this kind of "brain coprocessor" technology are under active development, such as systems that perturb the epileptic brain when a seizure is electrically observed, and prosthetics for amputees that record nerves to control artificial limbs and stimulate nerves to provide sensory feedback. Looking down the line, such system architectures might be capable of very advanced functions--providing just-in-time information to the brain of a patient with dementia to augment cognition, or sculpting the risk-taking profile of an addiction patient in the presence of stimuli that prompt cravings.

Looking ahead to the future, Boyden admits that we'll need to be careful:

Of course, giving machines the authority to serve as proactive human coprocessors, and allowing them to capture our attention with their computed priorities, has to be considered carefully, as anyone who has lost hours due to interruption by a slew of social-network updates or search-engine alerts can attest. How can we give the human brain access to increasingly proactive coprocessing technologies without losing sight of our overarching goals? One idea is to develop and deploy metrics that allow us to evaluate the IQ of a human plus a coprocessor, working together--evaluating the performance of collaborating natural and artificial intelligences in a broad battery of problem-solving contexts. After all, humans with Internet-based brain coprocessors (e.g., laptops running Web browsers) may be more distractible if the goals include long, focused writing tasks, but they may be better at synthesizing data broadly from disparate sources; a given brain coprocessor configuration may be good for some problems but bad for others. Thinking of emerging computational technologies as brain coprocessors forces us to think about them in terms of the impacts they have on the brain, positive and negative, and importantly provides a framework for thoughtfully engineering their direct, as well as their emergent, effects.

Searching for Kardashev III civilizations

Fascinating article by Paul Gilster over at Centauri Dreams: Interstellar Archaeology on the Galactic Scale. In the article, Gilster, discusses the work of Richard Carrigan of Fermilab and his recent paper, "Starry Messages: Searching for Signatures of Interstellar Archaeology."

Carrigan argues that we should broaden SETI's scope to include the archeological remnants of Kardashev III civilizations, namely those civilizations who successfully tapped into their Galaxy's entire energy output. At first blush, one would assume that a K3 galaxy would be immediately obvious, with every one if its stars enclosed in a Dysonian structure of some sort. But Carrigan makes the case that this might not be the case:

…what would happen for a civilization on its way to becoming a type III civilization, a type II.5 civilization so to say? If it was busily turning stars into Dyson spheres the civilization could create a “Fermi bubble” or void in the visible light from a patch of the galaxy with a corresponding upturn in the emission of infrared light. This bubble would grow following the lines of a suggestion attributed to Fermi… that patient space travelers moving at 1/1000 to 1/100 of the speed of light could span a galaxy in one to ten million years. Here “Fermi bubble” is used rather than “Fermi void”, in part because the latter is also a term in solid state physics and also because such a region would only be a visible light void, not a matter void.

As Gilster notes, this is long-term thinking in the richest sense; a patient, long-lived civilization could envelop a galaxy on a time-scale comparable to or shorter than the rotation period of the galaxy (considerably >~250 million years).

Civs who are busy turning stars into Dyson spheres should leave vast Fermi 'bubbles' whose infrared signature would flag their existence. But as Carrigon notes, detection might still elude us.

For example, we see M51, the Whirlpool galaxy, face-on at a distance of 30 million light years. We can say with some confidence that we see no unexplained voids larger than about five percent of M51's area, but any void features below this level would be hard to identify because of spiral galaxy structure. Elliptical galaxies might be better places to look for Fermi bubbles, because they display little structure, and potential voids should be far more pronounced.

And then there's the difficulty in separating artificial structure from natural phenomena where the tendency is to defer to the latter.

Gilster concludes:

I come back around to the premise behind interstellar archaeology, that unlike conventional SETI it does not require a civilization to have any intention of contacting us. There are numerous ways to proceed, involving the kind of Dyson sphere search Carrigan has himself conducted within our own galaxy, or looking at planetary atmospheres in hopes of finding not only biosignatures but the markers of an advanced industrial or post-industrial culture. As we continue the SETI hunt, keeping in mind how planetary change or deliberate decisions to expand into the galaxy could leave visible traces allows us to hunt for things advanced intelligence might do.

How many civilizations in our galaxy, for example, have already faced the end of their main sequence star’s lifetime? If the number is high, it may be that we can find evidence of their response in the form of planetary or stellar engineering, making stars of this description interesting targets for future searches. In any case, our model of SETI is changing as not only our technologies but our assumptions become more sophisticated, leaving us to ponder a universe in which the need for expansion or simple survival may have left its own detectable history.

Creatine improves working memory and general intelligence

This study goes back to 2003, but it's good to know, particularly if you're vegetarian or vegan:

Research undertaken by scientists at the University of Sydney and Macquarie University in Australia has shown that taking creatine, a compound found in muscle tissue, as a dietary supplement can give a significant boost to both working memory and general intelligence. The work, to be published in a forthcoming Proceedings B, a learned journal published by the Royal Society, monitored the effect of creatine supplementation on 45 young adult vegetarian subjects in a double-blind, placebo-controlled experiment.


Blackmore: I no longer believe religion is a virus of the mind

Susan Blackmore, after attending an "Explaining Religion" conference, now believes that the idea of religious belief as a virus has had its day:

...[R]eligious memes are adaptive rather than viral from the point of view of human genes, but could they still be viral from our individual or societal point of view? Apparently not, given data suggesting that religious people are happier and possibly even healthier than secularists. And at the conference, Ryan McKay presented experimental data showing that religious people can be more generous, cheat less and co-operate more in games such as the prisoner's dilemma, and that priming with religious concepts and belief in a "supernatural watcher" increase the effects.

So it seems I was wrong and the idea of religions as "viruses of the mind" may have had its day. Religions still provide a superb example of memeplexes at work, with different religions using their horrible threats, promises and tricks to out-compete other religions, and popular versions of religions outperforming the more subtle teachings of the mystical traditions. But unless we twist the concept of a "virus" to include something helpful and adaptive to its host as well as something harmful, it simply does not apply. Bacteria can be helpful as well as harmful; they can be symbiotic as well as parasitic, but somehow the phrase "bacterium of the mind" or "symbiont of the mind" doesn't have quite the same ring.

Hmmm, not sure how I feel about this. I don't understand Blackmore's insistence on having to associate viruses with exclusively negative impacts on the host. Viruses don't care what impact it has on the host so long as it has created the conditions for successful transmission and replication. Sure, viruses are nasty most of the time, but sometimes they can be neutral and even helpful; viruses have become quite useful in gene therepy, for example, allowing researchers to insert and remove genetic material from eukaryotic cells much easier (and with a higher degree of success) than ever before.

Now, all this said, I'm completely open to new ways of describing and analogizing the replicative strategies of memes. I would have no problem talking about the "bacterial" spread of memes; if the analogy accurately describes what's happening, then we should feel free to use it. I don't find this awkward, I find it exciting!

Oh, and full props to Blackmore for having the courage to claim she was wrong about something. While I don't necessarily believe she was wrong, I have great respect for her decision to come out and publicly challenge her own views.


Human Connectome Project to start mapping brain’s connections

The National Institutes of Health recently awarded grants totaling $40 million to map the human brain's connections in high resolution. It's hoped that better understanding of such connectivity will result in improved diagnosis and treatment of brain disorders.

To do so, state-of-the-art scanners will be employed to reveal the brain's intricate circuitry in high resolution.

The grants are the first awarded under the Human Connectome Project and they will support two collaborating research consortia. The first will be led by researchers at Washington University, St. Louis, and the University of Minnesota, Twin Cities, while the other will be led by investigators at Massachusetts General Hospital (MGH)/Harvard University, Boston, and the University of California Los Angeles (UCLA).

"We're planning a concerted attack on one of the great scientific challenges of the 21st Century," said Washington University's Dr. David Van Essen, Ph.D., who co-leads one of the groups with Minnesota's Kamil Ugurbil, Ph.D. "The Human Connectome Project will have transformative impact, paving the way toward a detailed understanding of how our brain circuitry changes as we age and how it differs in psychiatric and neurologic illness."

The Connectome projects are being funded by 16 components of NIH under its Blueprint for Neuroscience Research.


This highly coordinated effort will use state-of-the-art imaging instruments, analysis tools and informatics technologies — and all of the resulting data will be freely shared with the research community. Individual variability in brain connections underlies the diversity of human cognition, perception and motor skills, so understanding these networks promises advances in brain health.

One of the teams will map the connectomes in each of 1,200 healthy adults — twin pairs and their siblings from 300 families. The maps will show the anatomical and functional connections between parts of the brain for each individual, and will be related to behavioral test data. Comparing the connectomes and genetic data of genetically identical twins with fraternal twins will reveal the relative contributions of genes and environment in shaping brain circuitry and pinpoint relevant genetic variation. The maps will also shed light on how brain networks are organized.

In tooling up for the screening, the researchers will optimize magnetic resonance imaging (MRI) scanners to capture the brain’s anatomical wiring and its activity, both when participants are at rest and when challenged by tasks. All participants will undergo such structural and functional scans at Washington University. For these, researchers will use a customized MRI scanner with a magnetic field of 3 Tesla. This Connectome Scanner will incorporate new imaging approaches developed by consortium scientists at Minnesota and Advanced MRI Technologies and will provide ten-fold faster imaging times and better spatial resolution.

Creating these maps requires sophisticated statistical and visual informatics approaches; understanding the similarities and differences in these maps among sub-populations will improve our understanding of human brain in health and disease.

One step closer to technologically assisted telepathy

University of Utah scientists have successfully decoded words from brain signals, bringing us one step closer to realizing technologically assisted telepathy, or techlepathy.

In an early step toward letting severely paralyzed people speak with their thoughts, researchers translated brain signals into words using two grids of 16 microelectrodes implanted beneath the skull but atop the brain:

Using the experimental microelectrodes, the scientists recorded brain signals as the patient repeatedly read each of 10 words that might be useful to a paralyzed person: yes, no, hot, cold, hungry, thirsty, hello, goodbye, more and less.

Later, they tried figuring out which brain signals represented each of the 10 words. When they compared any two brain signals - such as those generated when the man said the words "yes" and "no" - they were able to distinguish brain signals for each word 76 percent to 90 percent of the time.

When they examined all 10 brain signal patterns at once, they were able to pick out the correct word any one signal represented only 28 percent to 48 percent of the time - better than chance (which would have been 10 percent) but not good enough for a device to translate a paralyzed person's thoughts into words spoken by a computer.

The researchers discovered that each spoken word produced varying brain signals, and thus the pattern of electrodes that most accurately identified each word varied from word to word. This finding supports the theory that closely spaced microelectrodes can capture signals from single, column-shaped processing units of neurons in the brain.

All this said, the process is far from perfect. The researchers were 85% accurate when distinguishing brain signals for one word from those for another when they used signals recorded from the facial motor cortex. They were 76% accurate when using signals from Wernicke's area (and combining data didn't help). The scientists were able to record 90% accuracy when they selected the five microelectrodes on each 16-electrode grid that were most accurate in decoding brain signals from the facial motor cortex. But in the more difficult test of distinguishing brain signals for one word from signals for the other nine words, the researchers initially were accurate only 28% of the time. However, when they focused on signals from the five most accurate electrodes, they identified the correct word 48% of the time.

So, there's lots of work to be done, but the proof of concept appears to be (mostly) there.

This research is being done to help those with locked-in syndrome, but once it gets developed there will be broader implications and applications. A more sophisticated and refined version of this technology, and in conjunction with other neural interfacing technologies, could result in the development of technologically assisted telepathy.


Turchin: SETI at risk of downloading a trojan horse

Russian physicist Alexey Turchin contends that passive SETI may be just as dangerous—if not more so—than active SETI:

I was fortune enough to be able to talk to Turchin at the Humanity+ Summit at Harvard earlier this year where he clarified his argument to me.

Turchin worries that humanity may be tricked by an out-of-control script that is propagating throughout the Galaxy. This script, which uses a pre-Singularity civilization as its vector, fools its hosts with a lure of some kind (e.g. immortality, access to the Galactic Internet, etc.) who in turn unwittingly build a device that produces a malign extraterrestrial artificial intelligence (ETAI). This ETAI then takes over all the resources of the planet so that it can re-broadcast itself into the cosmos in search of the next victim.

This concept is similar to Carl Sagan's interstellar transportation machine in Contact, except that it would work to destroy our civilization rather than see it move forward.

It's worth noting that this ETAI and its script may be a mutation of some sort, where no civilization was actually responsible for designing the damn thing. It's just a successful replicative schema that's following Darwinian principles.

It's also worth noting that I warned of this back in 2004.

Moving forward, Turchin suggests we raise awareness of the potential problem, change the guidelines for SETI research and consider the prohibition of SETI before we get our own AI.

Turchin's idea sounds ludicrous, but it's one of those crazy things that causes a nervous laugh. I think Turchin's idea needs to be discussed as there may be some merit to it. We need to be careful.


Andrew Revkin: Extreme weather in a warming world

"The need for developing resilience in the face of worst-case weather is glaring and urgent. With or without shifts propelled by the buildup of human-generated greenhouse gases, as populations continue rising in some of the world’s worst climatic “hot zones” — sub-Saharan Africa being the prime example — the exposure to risks from drought and heat will continue to climb, as well. In poor places, the risk is exacerbated by persistent poverty, dysfunctional government and a glaring lack of capacity to track climate conditions and design agricultural systems and water supplies around them." -- Andrew Revkin, "Extreme weather in a warming world"
