Got Lifeboat?

“The low-key launch of the new military unit reflects the Pentagon’s fear that the military might be seen as taking control over the nation’s computer networks.”

“Creation of the command, said Deputy Defense Secretary William Lynn at a recent meeting of cyber experts, ‘will not represent the militarization of cyberspace.’”

And where is our lifeboat?

It is easy to notice that the direct risks of collisions with asteroids decreases with technological development. First, they (or, exactly, our estimation of risks) decrease due to more accurate measurement of them — that is, at the expense of more accurate detection of dangerous asteroids and measurements of their orbits we could finally find that the real chance of impact is 0 in the next 100 year. (If, however, will be confirmed the assumption that we live during the episode of comet bombardment, the assessment of risk would increase 100 times to the background.) Second, it decreases due to an increase in our ability to reject asteroids.
On the other hand, the impact of falling asteroids become larger with time — not only because the population density increases, but also because the growing connectedness of the world system, resulting in that damage in one place can spread across the globe. In other words, although the probability of collisions is reducing, the indirect risks associated with the asteroid danger is increasing.
The main indirect risks are:
A) The destruction of hazardous industries in the place of the fall — for example, nuclear power plant. The entire mass of the station in such a case would evaporated and the release of radiation would be higher than in Chernobyl. In addition, there may be additional nuclear reactions because of sudden compression of the station when it is struck by asteroid. Yet the chances of a direct hit of an asteroid in the nuclear plants are small, but they grow with the growing number of stations.
B) There is a risk that even a small group of meteors, moving a specific angle in a certain place in the earth’s surface could lead to lunch of the system for the Prevention of rocket attacks and lead to an accidental nuclear war. Similar consequences could have a small air explosion of an asteroid (a few meters in size). The first option is more likely for developed superpowers system of warning (but which has flaws or unsecured areas in their ABM system, as in the Russian Federation), while the second — for the regional nuclear powers (like India and Pakistan, North Korea, etc.) which are not able to track missiles by radars, but could react to a single explosion.
C) The technology to drive asteroids in the future will create a hypothetical possibility to direct asteroids not only from Earth, but also on it. And even if there will be accidental impact of the asteroid, there will be talks about that it was sent on purpose. Yet hardly anyone will be sent to Earth asteroids, because such action can easily be detected, the accuracy is low and it need to be prepared for decades before event.
D) Deviations of hazardous asteroids will require the creation of space weapons, which could be nuclear, laser or kinetic. Such weapons could be used against the Earth or the spacecrafts of an opponent. Although the risk of applying it against the ground is small, it still creates more potential damage than the falling asteroids.
E) The destruction of the asteroid with nuclear explosion would lead to an increase in its affecting power at the expense of its fragments – to the greater number of blasts over a larger area, as well as the radioactive contamination of debris.
Modern technological means give possibility to move only relatively small asteroids, which are not global threat. The real danger is black comets in size of several kilometers which are moving on elongated elliptical orbits at high speeds. However, in the future, space can be quickly and cheaply explored through self-replicating robots based on nanoteh. This will help to create huge radio telescopes in space to detect dangerous bodies in the solar system. In addition, it is enough to plant one self-replicating microrobot on the asteroid, to multiply it and then it could break the asteroid on parts or build engines that will change its orbit. Nanotehnology will help us to create self-sustaining human settlements on the Moon and other celestial bodies. This suggests that the problem of asteroid hazard will in a few decades be outdated.
Thus, the problem of preventing collisions of the Earth with asteroids in the coming decades can only be a diversion of resources from the global risks:
First, because we are still not able to change orbits of those objects which actually can lead to the complete extinction of humanity.
Secondly, by the time (or shortly thereafter), when the nuclear missile system for destruction of asteroids will be created, it will be obsolete, because nanotech can quickly and cheaply harness the solar system by the middle of 21 century, and may, before .
And third, because such system at time when Earth is divided into warring states will be weapon in the event of war.
And fourthly, because the probability of extinction of humanity as a result of the fall of an asteroid in a narrow period of time when the system of deviation of the asteroids will be deployed, but powerful, nanotechnology is not yet established, is very small. This time period may be equal to 20 years, say from 2030 — until 2050, and the chances of falling bodies of 10 km size during this time, even if we assume that we live in a period comet bombardment, when the intensity is 100 times higher — is at 1 to 15 000 (based on an average frequency of the fall of bodies every 30 million years). Moreover, given the dynamics, we can reject the indeed dangerous objects only at the end of this period, and perhaps even later, as larger the asteroid, the more extensive and long-term project for its deviation is required. Although 1 to 15 000 is still unacceptable high risk, it is commensurate with the risk of the use of space weapons against the Earth.
In the fifth, anti-asteroid protection diverts attention from other global issues, the limited human attention and financial resources. This is due to the fact that the asteroid danger is very easy for understanding — it is easy to imagine, it is easy to calculate the probabilities and it is clear to the public. And there is no doubt of its reality, and there are clear ways for protection. (e.g. the probability of volcanic disaster comparable to the asteroid impact by various estimates, is from 5 to 20 times higher at the same level of energy – but we have no idea how it can be prevented.) So it differs from other risks that are difficult to imagine, that are impossible quantify, but which may mean the probability of complete extinction of tens of percent. These are the risks of AI, biotech, nanotech and nuclear weapons.
In the sixth, when talking about relatively small bodies like Apophis, it may be cheaper to evacuate the area of the fall than to deviate the asteroid. A likely the area of the impact will be ocean.
But I did not call to abandon antiasterod protection, because we first need to find out whether we live in the comet bombardment period. In this case, the probability of falling 1 km body in the next 100 years is equal to 6 %. (Based on data on the hypothetical fall in the last 10 000 years, like a comet Klovis http://en.wikipedia.org/wiki/Younger_Dryas_impact_event , traces of which can be 500 000 in the craters of similar entities called Carolina Bays http://en.wikipedia.org/wiki/Carolina_bays crater, and around New Zealand in 1443 http://en.wikipedia.org/wiki/Mahuika_crater and others 2 impacts in last 5 000 years , see works of http://en.wikipedia.org/wiki/Holocene_Impact_Working_Group ). We must first give power to the monitoring of dark comets and analysis of fresh craters.

“An inventory of deadly germs and toxins at an Army biodefense lab in Frederick found more than 9,200 vials of material that was unaccounted for in laboratory records, Fort Detrick officials said Wednesday. The 13 percent overage mainly reflects stocks left behind in freezers by researchers who retired or left Fort Detrick since the biological warfare defense program was established there in 1943, said Col. Mark Kortepeter, deputy commander of the U.S. Army Medical Research Institute of Infectious Diseases.”

Given that “The material was in tiny, 1mm vials that could easily be overlooked,” and included serum from Korean hemorrhagic fever patients, the lack of adequate inventory controls to this point creates the impression that any number of these vials could be outside their lab. Of course, they assure us they have it all under control. Which will be cold comfort if we don’t have a lifeboat.

Another friend, filmmaker Meg McLain has noticed that orbital hotels and space cruise liners are all vapor ware. Indeed, we’ve had few better depictions of realistic “how it would feel” space resorts since 1968’s Kubrick classic “2001: A Space Odyssey.” Remember the Pan Am flight to orbit, the huge hotel and mall complex, and the transfer to a lunar shuttle? To this day I know people who bought reservation certificates for whenever Pan Am would begin to fly to the Moon.

In 2004, after the X Prize victory, Richard Branson announced that Virgin Galactic would be flying tourists by 2007. So far, none.

A little later, Bigelow announced a fifty million dollar prize if only tourists could be launched to orbit by January 2010. I expect the prize money won’t be claimed in time.

Why? Could it be that the government is standing in the way? And if tourism in space can’t be “permitted” what of a lifeboat colony?

Meg has set out to make a documentary film about how the human race has arrived four decades after the Moon landing and still no tourist stuff. Two decades after Kitty Hawk, a person could fly across the country; three decades, across any ocean.

Where are the missing resorts?

“We have the serious opportunity in our hands right now of terminating the era of government absolutely, and so of removing from the human race the threat of ever more brutal tyranny ending only with WMD annihilation–while opening up vistas of peaceful prosperity and technological progress which even a realist like myself cannot find words to describe. ”

Avoiding those terrible events is what building our Lifeboat is all about. Got Lifeboat?

“After more than 120,000 years trapped beneath a block of ice in Greenland, a tiny microbe has awoken. … The new bacteria species was found nearly 2 miles (3 km) beneath a Greenland glacier, where temperatures can dip well below freezing, pressure soars, and food and oxygen are scarce. ‘We don’t know what state they were in,’ said study team member Jean Brenchley of Pennsylvania State University. ‘They could’ve been dormant, or they could’ve been slowly metabolizing, but we don’t know for sure.’”

It is yet another interesting possibility against which humans should prepare to protect ourselves. Where is our Lifeboat?

In the next decade or so, a new type of desktop appliance will be developed—a nanofactory that consists of very many productive nanosystems—atomically precise nanoscale machines that work together to build bulk amounts of atomically precise products.

The Foresight Technology Roadmap for Productive Nanosystems has identified a number of different approaches for building these atomically precise systems of machines that can produce other nanosystems http://www.foresight.org/roadmaps/. These approaches include Paul Rothemund’s DNA Origami, Christopher Schafmeister’s Bis-proteins, Joe Lynden’s Patterned Atomic Layer Epitaxy, and Robert Freitas and Ralph Merkle’s Diamondoid Mechanosynthesis http://www.rfreitas.com/Nano/JNNDimerTool.pdf, http://e-drexler.com/d/05/00/DC10C-mechanosynthesis.pdf, and http://www.molecularassembler.com/Papers/JCTNPengFeb06.pdf. Each of these approaches has the potential of building the numerous nanoscale electronic, mechanical, and structural components that comprise productive nanosystems.

The ultimate result will be a nanofactory that can build virtually anything—limited only by the laws of physics, the properties of the input feedstock, and the software that controls the device.

The concern is that this relatively primitive application—if successfully deployed as expected—will pose significant challenges, even if nobody accidentally makes a mistake or puts it to evil ends. Consider the simple, safe, and optimistic possibilities made possible by a nanofactory that can build a wide variety of atomically precise, large-scale products out of a few different input elements (say carbon, hydrogen, oxygen, iron, silicon, germanium, boron, phosphorus, and titanium) http://www.MolecularAssembler.com/Nanofactory. The factory itself would not be nano-sized; it would be an appliance that is approximately the same size as a desktop printer. However, its multi-material 3D output products would be atomically precise at the nanoscale.

The first and most valuable product of a nanofactory will be another nanofactory. The second most valuable product will be a system that refills the nanofactory’s “inkjet cartridge” using inexpensive feedstock, and the third will be a machine that turns sand into photovoltaic solar cells (with which to power the nanofactory). It is not clear what would one would print next. Programmable material for a holodeck? Wearable supercomputers? A few pounds of medical nanobots?

In any case, a few months to a few years after the first commercial release of a nanofactory, almost everyone will have one. It is not clear what the price might be—perhaps $1000. The price could not drop to zero, though it might approach the cost of dirt, sunshine, and the time required to print a nanofactory.

Diamond and its carbon-based relatives are an engineer’s best friend; being 50 times stronger than steel, only their atomic structure differentiates it from coal. Once people have a printer that can inexpensively make arbitrary, atomically perfect diamondoid nanostructures out of carbon, they are going to make everything out of it—from wearable supercomputers and skyscrapers that reach Low Earth Orbit to medical nanobots and flying cars—anything that doesn’t violate the laws of physics and has a CAD file description available on the web. Therefore, any cheap sources of carbon will be snatched up quickly.

Because human desire is essentially infinite, the demand for carbon will reach very high levels fairly quickly.

Air is free, and so is the carbon dioxide in it.

If taking carbon dioxide out of the air became economically favorable (and with inexpensive solar power it probably will be), then the result will be a ‘tragedy of the commons’. This would solve CO₂-caused global warming with a vengeance, but would result in global freezing—and worse. If enough carbon dioxide in the air was removed, plant life would start to die.

Futurist Keith Henson has predicted that to counteract this outcome, the Sierra Club will frantically strip-mine all the coal under Wyoming and burn it as dirty a manner possible to save the rain forests. If Henson is correct, then Congress might pass laws that make it illegal to take CO₂ from the air. But how will the government enforce a ban against unauthorized CO₂ extraction?

Nanotechnology, of course.

Unfortunately, a government with unfettered nanotechnology-enhanced enforcement powers would likely be a dictatorship that makes the totalitarian regime of Orwell’s 1984 look like a kindergarten playground.

An alternative to a dictatorship would involve ownership of air. This sounds strange and preposterous until we remember that the American Indians thought that land ownership was strange and preposterous.

A more jarring alternative might involve the re-engineering of plants so that they can live without carbon dioxide, perhaps by using silica as a structure material (as diatoms do). Do we really trust ourselves to recreate Earth’s biosphere in such a drastic manner? Some optimists will tell us not to worry about such drastic genetic modification on the ecosystem; we will back up the whole thing on the web somewhere, and use modern software revision-tracking software to keep it safe http://tortoisesvn.net/.

Admittedly, these scenarios seem rather far-fetched. However, as Foresight Institute co-founder Christine Peterson put it, “If you look out into the long-term future and what you see looks like science fiction, it might be wrong. But if it doesn’t look like science fiction, it’s definitely wrong” http://www.washingtonpost.com/wp-dyn/content/article/2008/04…28_pf.html.

We are not yet at the level of technological maturity at which we can confidently assert that widescale nanofactory development and distribution is inevitable. Of the four main approaches to Productive Nanosystems, only the most rudimentary lab demos have proven the concepts. Therefore, the suggestion that nanofactories will alter the conditions of anthropogenic global warming may be met with skepticism — as it should. However, in light of the exponential progress in nanotechnology in the past few years, it is likely that some version of the carbon dioxide tragedy of the commons will happen in some form or another. Researchers, policy makers, and the public at large must become aware of these possibilities, and thoughtfully analyze them. Otherwise disruptive events may cause panic, as most scenarios predict a quick transition from initial invention to wide distribution of these technologies.

Ultimately, this prediction means two things. First, that wasting precious time, money, and effort on stopping global warming will increase the risk of other, more serious catastrophes. Second, we will need to set aside any conservative values regarding the preservation of the Earth’s ecosystem as it currently exists. Change will happen. The good news is that a Space Pier http://autogeny.org/tower/tower.html and other low-cost methods to orbit will be available for conservatives who are intent on preserving the status quo biosphere elsewhere in the solar system. Of course, these are the same people who are probably the most emotionally resistant to leaving, which might lead to conflicts.

Howard Bloom gently points out that “Nature is not a motherly protector”. Putting it more bluntly and extending the anthropomorphism, Mother Nature is a brutal psychopath who uncaringly tortures and slaughters her children. She does not build nice little eco-friendly Gardens of Eden. In fact, there have been 148 major die-offs, and six much bigger mass extinctions (in which over 90% of species on this planet were wiped out—each and every time). Those die-offs resulted from natural physical disturbances in a universe that is fine-tuned to allow carbon-based life to emerge. It’s a mixed message, but the message is simple: Adapt or die. Nanotechnology will not change that message. However, it will provide us with better biotech tools that will enable us to (for better or worse) manipulate our bodies and brains.

As the nanotechnology revolution begins, we will need to think hard about its secondary effects and ethical implications. The sheer magnitude of changes will cause us to consider carefully our ultimate role in the universe, our essential nature as human persons, the meaning of our lives, and what we really, really desire.
