I am presenting disruption events for humans and also for biospheres and planets and where I can correlating them with historical frequency and scale.

There has been previous work on categorizing and classifying extinction events. There is Bostroms paper and there is also the work by Jamais Cascio and Michael Anissimov on classification and identifying risks (presented below).

A recent article discusses the inevtiable “end of societies” (it refers to civilizations but it seems to be referring more to things like the end of the roman empire, which still ends up later with Italy, Austria Hungary etc… emerging)

The theories around complexity seem me that to be that core developments along connected S curves of technology and societal processes cap out (around key areas of energy, transportation, governing efficiency, agriculture, production) and then a society falls back (soft or hard dark age, reconstitutes and starts back up again).

Here is a wider range of disruption. Which can also be correlated to frequency that they have occurred historically.

High growth drop to Low growth (short business cycles, every few years)
Recession (soft or deep) Every five to fifteen years.
Depressions (50−100 years, can be more frequent)

List of recessions for the USA (includes depressions)

Differences recession/depression

Good rule of thumb for determining the difference between a recession and a depression is to look at the changes in GNP. A depression is any economic downturn where real GDP declines by more than 10 percent. A recession is an economic downturn that is less severe. By this yardstick, the last depression in the United States was from May 1937 to June 1938, where real GDP declined by 18.2 percent. Great Depression of the 1930s can be seen as two separate events: an incredibly severe depression lasting from August 1929 to March 1933 where real GDP declined by almost 33 percent, a period of recovery, then another less severe depression of 1937–38. (Depressions every 50–100 years. Were more frequent in the past).

Dark age (period of societal collapse, soft/light or regular)
I would say the difference between a long recession and a dark age has to do with breakdown of societal order and some level of population decline / dieback, loss of knowledge/education breakdown. (Once per thousand years.)

I would say that a soft dark age is also something like what China had from the 1400’s to 1970.
Basically a series of really bad societal choices. Maybe something between depressions and dark age or something that does not categorize as neatly but an underperformance by twenty times versus competing groups. Perhaps there should be some kind of societal disorder, levels and categories of major society wide screw ups — historic level mistakes. The Chinese experience I think was triggered by the renunciation of the ocean going fleet, outside ideas and tech, and a lot of other follow on screw ups.

Plagues played a part in weakening the Roman and Han empires.

Societal collapse talk which includes Toynbee analysis.

Toynbee argues that the breakdown of civilizations is not caused by loss of control over the environment, over the human environment, or attacks from outside. Rather, it comes from the deterioration of the “Creative Minority,” which eventually ceases to be creative and degenerates into merely a “Dominant Minority” (who forces the majority to obey without meriting obedience). He argues that creative minorities deteriorate due to a worship of their “former self,” by which they become prideful, and fail to adequately address the next challenge they face.

My take is that the Enlightenment would strengthened with a larger creative majority, where everyone has a stake and capability to creatively advance society. I have an article about who the elite are now.

Many now argue about how dark the dark ages were not as completely bad as commonly believed.
The dark ages is also called the Middle Ages

Population during the middle ages

Between dark age/social collapse and extinction. There are levels of decimation/devastation. (use orders of magnitude 90+%, 99%, 99.9%, 99.99%)

Level 1 decimation = 90% population loss
Level 2 decimation = 99% population loss
Level 3 decimation = 99.9% population loss

Level 9 population loss (would pretty much be extinction for current human civilization). Only 6–7 people left or less which would not be a viable population.

Can be regional or global, some number of species (for decimation)

Categorizations of Extinctions, end of world categories

Can be regional or global, some number of species (for extinctions)

== The Mass extinction events have occurred in the past (to other species. For each species there can only be one extinction event). Dinosaurs, and many others.

Unfortunately Michael’s accelerating future blog is having some issues so here is a cached link.

Michael was identifying manmade risks
The Easier-to-Explain Existential Risks (remember an existential risk
is something that can set humanity way back, not necessarily killing
everyone):

1. neoviruses
2. neobacteria
3. cybernetic biota
4. Drexlerian nanoweapons

The hardest to explain is probably #4. My proposal here is that, if
someone has never heard of the concept of existential risk, it’s
easier to focus on these first four before even daring to mention the
latter ones. But here they are anyway:

5. runaway self-replicating machines (“grey goo” not recommended
because this is too narrow of a term)
6. destructive takeoff initiated by intelligence-amplified human
7. destructive takeoff initiated by mind upload
8. destructive takeoff initiated by artificial intelligence

Another classification scheme: the eschatological taxonomy by Jamais
Cascio on Open the Future. His classification scheme has seven
categories, one with two sub-categories. These are:

0:Regional Catastrophe (examples: moderate-case global warming,
minor asteroid impact, local thermonuclear war)
1: Human Die-Back (examples: extreme-case global warming,
moderate asteroid impact, global thermonuclear war)
2: Civilization Extinction (examples: worst-case global warming,
significant asteroid impact, early-era molecular nanotech warfare)
3a: Human Extinction-Engineered (examples: targeted nano-plague,
engineered sterility absent radical life extension)
3b: Human Extinction-Natural (examples: major asteroid impact,
methane clathrates melt)
4: Biosphere Extinction (examples: massive asteroid impact,
“iceball Earth” reemergence, late-era molecular nanotech warfare)
5: Planetary Extinction (examples: dwarf-planet-scale asteroid
impact, nearby gamma-ray burst)
X: Planetary Elimination (example: post-Singularity beings
disassemble planet to make computronium)

A couple of interesting posts about historical threats to civilization and life by Howard Bloom.

Natural climate shifts and from space (not asteroids but interstellar gases).

Humans are not the most successful life, bacteria is the most successful. Bacteria has survived for 3.85 billion years. Humans for 100,000 years. All other kinds of life lasted no more than 160 million years. [Other species have only managed to hang in there for anywhere from 1.6 million years to 160 million. We humans are one of the shortest-lived natural experiments around. We’ve been here in one form or another for a paltry two and a half million years.] If your numbers are not big enough and you are not diverse enough then something in nature eventually wipes you out.

Following the bacteria survival model could mean using transhumanism as a survival strategy. Creating more diversity to allow for better survival. Humans adapted to living under the sea, deep in the earth, in various niches in space, more radiation resistance,non-biological forms etc… It would also mean spreading into space (panspermia). Individually using technology we could become very successful at life extension, but it will take more than that for a good plan for human (civilization, society, species) long term survival planning.

Other periodic challenges:
142 mass extinctions, 80 glaciations in the last two million years, a planet that may have once been a frozen iceball, and a klatch of global warmings in which the temperature has soared by 18 degrees in ten years or less.

In the last 120,000 years there were 20 interludes in which the temperature of the planet shot up 10 to 18 degrees within a decade. Until just 10,000 years ago, the Gulf Stream shifted its route every 1,500 years or so. This would melt mega-islands of ice, put out our coastal cities beneath the surface of the sea, and strip our farmlands of the conditions they need to produce the food that feeds us.

The solar system has a 240-million-year-long-orbit around the center of our galaxy, an orbit that takes us through interstellar gas clusters called local fluff, interstellar clusters that strip our planet of its protective heliosphere, interstellar clusters that bombard the earth with cosmic radiation and interstellar clusters that trigger giant climate change.

Many of you have recently read that a research team at the University of Illinois led by Min-Feng Yu has developed a process to grow nanowires of unlimited length. The same process also allows for the construction of complex, three-dimensional nanoscale structures. If this is news to you, please refer to the links below.

It’s easy to let this news item slip past before its implications have a chance to sink in.

Professor Yu and his team have shown us a glimpse of how to make nanowire based materials that will, once the technology is developed more fully, allow for at least two very significant enhancements in materials science.

1. Nanowires that will be as long as we want them to be. The only limitations that seem to be indicated are the size of the “ink” reservoir and the size of spool that the nanowires are wound on. Scale up the ink supply and the scale up size of the spool and we’ll soon be making cables and fabric. Make the cables long enough and braid enough of them them together and the Space Elevator Games may become even more exciting to watch.

2. It should also lend itself very nicely to 3D printing of complex nanoscale structures. Actually building components that will allow for the bootstrapping of a desktop sized molecular manufacturing fab seems like it’s a lot closer than it was just a short time ago.

All of this highlights the need to more richly fund the Lifeboat Foundation in general and the Lifeboat Foundation’s NanoShield program in particular so that truly transformative technologies like these can be brought to market in a way that minimizes the risks of their powers being used for ill.

If you can, please consider donating to the Lifeboat Foundation. Every dollar helps us to safely bring a better world into being. The species you help save may be your own.

The Defense Advanced Research Projects Agency (DARPA) gave a $540,000 grant to researchers from Rice University to do a fast-tracked 9-month study on a new anti-radiation drug based on carbon nanotubes:

“More than half of those who suffer acute radiation injury die within 30 days, not from the initial radioactive particles themselves but from the devastation they cause in the immune system, the gastrointestinal tract and other parts of the body,” said James Tour, Rice’s Chao Professor of Chemistry, director of Rice’s Carbon Nanotechnology Laboratory (CNL) and principal investigator on the grant. “Ideally, we’d like to develop a drug that can be administered within 12 hours of exposure and prevent deaths from what are currently fatal exposure doses of ionizing radiation.” […]

The new study was commissioned after preliminary tests found the drug was greater than 5,000 times more effective at reducing the effects of acute radiation injury than the most effective drugs currently available. […]

The drug is based on single-walled carbon nanotubes, hollow cylinders of pure carbon that are about as wide as a strand of DNA. To form NTH, Rice scientists coat nanotubes with two common food preservatives — the antioxidant compounds butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) — and derivatives of those compounds.

An interesting side benefit of the drug might be that it could also potentially help cancer patients who are undergoing radiation treatment.

Reposted from Next Big Future which was advancednano.

A 582,970 base pair sequence of DNA has been synthesized.

It’s the first time a genome the size of a bacterium has chemically been synthesized that’s about 20 times longer than [any DNA molecule] synthesized before.

This is a huge increase in capability. It has broad implications for DNA nanotechnology and synthetic biology.

It is particularly relevant for the lifeboat foundation bioshield project

This means that the Venter Institute is on the brink of sythesizing a new bacterial life.

The process to synthesize and assemble the synthetic version of the M. genitalium chromosome

began first by resequencing the native M. genitalium genome to ensure that the team was starting with an error free sequence. After obtaining this correct version of the native genome, the team specially designed fragments of chemically synthesized DNA to build 101 “cassettes” of 5,000 to 7,000 base pairs of genetic code. As a measure to differentiate the synthetic genome versus the native genome, the team created “watermarks” in the synthetic genome. These are short inserted or substituted sequences that encode information not typically found in nature. Other changes the team made to the synthetic genome included disrupting a gene to block infectivity. To obtain the cassettes the JCVI team worked primarily with the DNA synthesis company Blue Heron Technology, as well as DNA 2.0 and GENEART.

From here, the team devised a five stage assembly process where the cassettes were joined together in subassemblies to make larger and larger pieces that would eventually be combined to build the whole synthetic M. genitalium genome. In the first step, sets of four cassettes were joined to create 25 subassemblies, each about 24,000 base pairs (24kb). These 24kb fragments were cloned into the bacterium Escherichia coli to produce sufficient DNA for the next steps, and for DNA sequence validation.

The next step involved combining three 24kb fragments together to create 8 assembled blocks, each about 72,000 base pairs. These 1/8th fragments of the whole genome were again cloned into E. coli for DNA production and DNA sequencing. Step three involved combining two 1/8th fragments together to produce large fragments approximately 144,000 base pairs or 1/4th of the whole genome.

At this stage the team could not obtain half genome clones in E. coli, so the team experimented with yeast and found that it tolerated the large foreign DNA molecules well, and that they were able to assemble the fragments together by homologous recombination. This process was used to assemble the last cassettes, from 1/4 genome fragments to the final genome of more than 580,000 base pairs. The final chromosome was again sequenced in order to validate the complete accurate chemical structure.

The synthetic M. genitalium has a molecular weight of 360,110 kilodaltons (kDa). Printed in 10 point font, the letters of the M. genitalium JCVI-1.0 genome span 147 pages.

In a recent conversation on our discussion list, Ben Goertzel, a rising star in artificial intelligence theory, expressed skepticism that we could keep a “modern large-scale capitalist representative democracy cum welfare state cum corporate oligopoly” going for much longer.

Indeed, our complex civilization currently does seem to be under a lot of stress.

Lifeboat Foundation Scientific Advisory Board member and best-selling author David Brin’s reply was quite interesting.

David writes:

* THE UNLIKELINESS OF A POSITIVE SUM SOCIETY

Today’s “modern large-scale capitalist representative democracy cum welfare state cum corporate oligopoly” works largely because the systems envisioned by John Locke and Adam Smith have burgeoned fantastically, producing synergies in highly nonlinear ways that another prominent social philosopher — Karl Marx — never imagined. Ways that neither Marx nor the ruling castes of prior cultures even could imagine.

Through processes of competitive creativity and reciprocal accountability, the game long ago stopped being zero-sum (I can only win if you lose) and became prodigiously positive-sum. (We all win, though I’d still like to win a little more than you.) (See Robert Wright’s excellent book “Non-Zero”.)

Yes, if you read over the previous paragraph, I sound a lot like some of the boosters of FIBM or Faith In Blind Markets… among whom you’ll find the very same neocons and conspiratorial kleptocrats who I accuse of ruining markets! Is that a contradiction?

Not at all. Just as soviet commissars recited egalitarian nostrums, while relentlessly quashing freedom in the USSR, many of our own right-wing lords mouth “pro-enterprise” lip service, while doing everything they can to cheat and foil competitive markets. To kill the golden goose that gave them everything.

The problem is that our recent, synergistic system has always had to push uphill against a perilous slope of human nature. The Enlightenment is just a couple of centuries old. Feudalism/tribalism had uncountable millennia longer to work a selfish, predatory logic into our genes, our brains. We are all descended from insatiable men, who found countless excuses for cheating, expropriating the labor of others, or preserving their power against challenges from below. Not even the wisest of us can guarantee we’d be immune from temptation to abuse power, if we had it.

Some, like George Washington, have set a pretty good example. They recognize these backsliding trends in themselves, and collaborate in the establishment of institutions, designed to let accountability flow. Others perform lip-service, then go on to display every dismal trait that Karl Marx attributed to shortsighted bourgeois “exploiters.”

Indeed, it seems that every generation must face this ongoing battle, between those who “get” what Washington and many others aimed for — the positive-sum game — and rationalizers who are driven by our primitive, zero-sum drives. A great deal is at stake, at a deeper level that mere laws and constitutions. Moreover, if the human behavior traits described by Karl Marx ever do come roaring back, to take hold in big ways, then so might some of the social scenarios that he described.

* SHOULD WE — SERIOUSLY — HAVE A FRESH LOOK AT OLD KARL MARX?

Do you, as an educated 21st Century man or woman, know very much about the controversy that transfixed western civilization for close to a century and a half? A furious argument, sparked by a couple of dense books, written by a strange little bearded man? Or do you shrug off Marx as an historical oddity? Perhaps a cousin of Groucho?

Were our ancestors — both those who followed Marx and those who opposed him — stupid to have found him interesting or to have fretted over the scenarios he foretold?

I often refer to Marx as the greatest of all science fiction authors, because — while his long-range forecasts nearly all failed, and some of his premises (like the labor theory of value) were pure fantasy — he nevertheless shed heaps of new light and focused the attention of millions upon many basics of both economics and human nature. As a story-spinner, Marx laid down some “if this goes on” thought-experiments that seemed vividly plausible to people of his time, and for a century afterwards. People who weren’t stupid. People who were, in fact, far more intimate with the consequences of social stratification than we have been, in the latest, pampered generation.

As virtually the inventor of the term “capitalism,” Marx ought to be studied (and criticized) by anyone who wants to understand our way of life.

What’s been forgotten, since the fall of communism, is that the USSR’s ‘experiment’ was never even remotely “Marxism.” And, hence, we cannot simply watch “The Hunt For Red October” and then shrug off the entire set of mental and historical challenges. By my own estimate, he was only 50% a deluded loon — a pretty good ratio, actually. (I cannot prove that I’m any better!) The other half was brilliant (ask any economist) and still a powerful caution. Moreover, anyone who claims to be a thinker about our civilization should be able to argue which half was which.

Marx’s forecasts seem to have failed not because they were off-base in extrapolating the trends of 19th Century bourgeois capitalism. He extrapolated fine. But what he never imagined was that human beings might intelligently perceive, and act to alter those selfsame powerful trends! While living amid the Anglo Saxon Enlightenment, Marx never grasped its potential for self-criticism, reconfiguration and generating positive-sum alternatives.

A potential for changing or outgrowing patterns that he (Marx) considered locked, in stone.

Far from the image portrayed by simplistic FIBM cultists, we did not escape Marx’s scenarios through laissez-faire indolence. In fact, his forecasts failed — ironically — because people read and studied Karl Marx.

* HUMAN NATURE ALWAYS CONSPIRES AGAINST ENLIGHTENMENT

This much is basic. We are all descended from rapacious, insatiable cheaters and (far worse) rationalizers. Every generation of aristocrats (by whatever surface definition you use, from soviet nomenklatura, theocrats, or royalty to top CEOs) will come up with marvelous excuses for why they should be allowed to go back to oligarchic rule-by-cabal and “guided allocation of resources” (GAR), instead of allowing open competition/cooperation to put their high status under threat. Indeed, those who most stridently tout faith in blind markets are often among the worst addicts of GAR.

In particular, it is the most natural thing in the world for capital owners and GAR-masters to behave in the way that Karl Marx modeled. His forecast path of an ever-narrowing oligarchy — followed ultimately by revolution — had solid historical grounding and seemed well on its way to playing out.

What prevented it from happening — and the phenomenon that would have boggled poor old KM — was for large numbers of western elites and commonfolk to weigh alternatives, to see these natural human failure modes, and to act intelligently against them. He certainly never envisioned a smart society that would extend bourgeois rights and social mobility to the underclasses. Nor that societies might set up institutions that would break entirely from his model, by keeping things open, dynamic, competitive, and reciprocally accountable, allowing the nonlinear fecundity of markets and science and democracy to do their positive-sum thing.

In his contempt for human reasoning ability (except for his own), Marx neglected to consider that smart men and women would actually read his books and decide to remodel society, so that his scenario would not happen. So that revolution, when it came, would be gradual, ongoing, moderate, lawful, and generally non-confiscatory, especially since the positive sum game lets the whole pie grow, while giving bigger slices to all.

In fact, I think the last ninety years may be partly modeled according to how societies responded to the Marxian meme. First, in 1917, came the outrageously stupid Soviet experiment, which simply replaced Czarist monsters with another clade of oppressors, that mouthed different sanctimonious slogans. Then the fascist response, which was a deadly counter-fever, fostered by even more-stupid European elites. Things were looking pretty bleak.

* THE ENLIGHTENMENT STRIKES BACK

Only then this amazing thing that happened — especially in America — where a subset of wealthy people, like FDR, actually read Marx, saw the potential pathway into spirals of crude capital formation, monopolization, oppression and revolution… and decided to do something about it, by reforming the whole scenario away! By following Henry Ford’s maxim and giving all classes a stake — which also meant ceding them a genuine share of power. A profoundly difficult thing for human beings to do,

Those elites who called FDR a “traitor to his class” were fools. The smart ones knew that he saved their class, and enabled them to enjoy wealth in a society that would be vastly more successful, vibrant, fun, fair, stable, safe and fantastically more interesting.

I believe we can now see the recent attempted putsch by a neocon-kleptocrat aristocratic cabal in broad but simple and on-target context. We now have a generation of wealthy elites who (for the most part) have never read Marx! Who haven’t a clue how chillingly plausible his scenarios might be, if enlightenment systems did not provide an alternative to revolution. And who blithely assume that they are in no danger, whatsoever, of those scenarios ever playing out.

Shortsightedly free from any thought or worry about the thing that fretted other aristocracies — revolution — they feel no compunction or deterrence from trying to do the old/boring thing… giving in to the ancient habit… using influence and power to gather MORE influence and power at the expense of regular people, all with the aim of diminishing the threat of competition from below. And all without extrapolating where it all might lead, if insatiability should run its course.

What we would call “cheating,” they rationalize as preserving and enhancing a natural social order. Rule by those best suited for the high calling of rulership. Those born to it. Or Platonic philosopher kings. Or believers in the right set of incantations.

* REVENGE OF THE DARKSIDE LORDS

Whatever the rationalizations, it boils down to the same old pyramid that failed the test of governance in nearly 100% of previous civilizations, always and invariably stifling creativity while guiding societies to delusion and ruin. Of course, it also means a return to zero-sum logic, zero-sum economics, zero-sum leadership thinking, a quashing of nonlinear synergies… the death of the Enlightenment.

Mind you! I am describing only a fraction of today’s aristocracy of wealth or corporate power. I know half a dozen billionaires, personally, and I’d wager none of them are in on this klepto-raid thing! They are all lively, energetic, modernistic, competitive and fizzing with enthusiasm for a progressive, dynamic civilization. A civilization that’s (after all) been very good to them.

They may not have read Marx (in this generation, who has?) But self-made guys like Bezos and Musk and Page etc share the basic values of an Enlightenment. One in which some child from a poor family may out-compete overprivileged children of the rich, by delivering better goods, innovations or services. And if that means their own privileged kids will also have to work hard and innovate? That’s fine by them! Terrific.

When the chips come down, these better billionaires may wind up on our side, weighing the balance and perceiving that their enlightened, long range self-interest lies with us. With the positive-sum society. Just the way FDR and his smart-elite friends did, in the 1930s… while the dumber half of the aristocracy muttered and fumed.

We can hope that the better-rich will make this choice, when the time comes. But till then, the goodguy (or, at least with-it) billionaires are distracted, busy doing cool things, while the more old-fashioned kind — our would-be lords — are clustering together in tight circles, obeying 4,000 years of ingrained instinct, whispering and pulling strings, appointing each other to directorships, awarding unearned golden parachutes, conniving for sweetheart deals, and meddling in national policy…

…doing the same boring thing that human beings will always do — what you and I would be tempted to do — whenever you mix un-curbed ego with unaccountable privilege, plus a deficit of brains.

Robert Freitas, Jr., Lifeboat Foundation Fellow and head of the Lifeboat Foundation’s Nanomedicine Division has won the 2007 Foresight Institute Feynman Prize in Communication.

Dr. Pearl Chin, President of the Foresight Nanotech Institute, said Freitas received the award for “pioneering the study and communication of the benefits to be obtained from an advanced nanomedicine that will be made possible by molecular manufacturing [and for having] worked to develop and communicate a path from our current technology base to a future technology base that will enable advanced nanomedicine.”

Prior to his Feynman Prize win Robert shared the Lifeboat Foundation’s 2006 Guardian Award with technology legend Bill Joy. Freitas and Joy shared the Guardian award for their many years of work on mitigating risks posed by advanced technologies.

A better atomic force microscope from Japan:

Credit: Oscar Custance, Osaka University

“A new type of atomic force microscope (AFM) has been developed that can “fingerprint” the chemical identity of individual atoms on a material’s surface. This is one step ahead of existing AFMs, which can only detect the position of atoms. The device determines local composition and structure using a precise calibration method, and can even be used to manipulate specific atomic species. The team demonstrated their “fingerprinting” technique by using an atomic force microscope (AFM) to distinguish atoms of tin (blue) and lead (green) deposited on a silicon substrate (red).”

Here is the associated article (subscription req’d).

Here’s the graphene transistor everyone’s been talking about:

One atom thick, 50 atoms wide. Here is an article going over the advance. It states that the transistors are not likely to be completely ready by 2025, but this estimate seems conservative.

Scientists from Duke recently achieved the new size record for a programmable synthetic nanostructure:

These DNA grids were formed by hierarchial self-assembly. The article on the development states, that the “grid-like structures consist of components that can be independently modified to create arbitrary patterns for different purposes”.

Reminds me of CRN’s cubic micron DNA structure ideas.

The trillion-dollar question is, “when will these advances lead to freely programmable, self-replicating molecular assemblers?” Some scientists are betting on the 2015–2020 timeframe, others say “never”.

“The importance of the space sector can be emphasized by the number of spacecrafts launched. In the period from 1957 till 2005, 6376 spacecraft have been launched at an average of 133 per year. The has been a decrease in the number of spacecrafts launched in the recent years with 78 launched in 2005. Of the 6378 launches, 56.8% were military spacecrafts and 43.2 were civilian. 245 manned missions have been launched in this period. 1674 communication or weather satellites were also launched. The remaining spacecraft launches has been exploration missions.”
