There are dozens of published existential risks; there are undoubtedly many more that Nick Bostrom did not think of in his paper on the subject. Ideally, the Lifeboat Foundation and other organizations would identify each of these risks and take action to combat them all, but this simply isn’t realistic. We have a finite budget and a finite number of man-hours to spend on the problem, and our resources aren’t even particularly large compared with other non-profit organizations. If Lifeboat or other organizations are going to take serious action against existential risk, we need to identify the areas where we can do the most good, even at the expense of ignoring other risks. Humans like to totally eliminate risks, but this is a cognitive bias; it does not correspond to the most effective strategy. In general, when assessing existential risks, there are a number of useful heuristics:

- Any risk which has become widely known, or an issue in contemporary politics, will probably be very hard to deal with. Thus, even if it is a legitimate risk, it may be worth putting on the back burner; there’s no point in spending millions of dollars for little gain.

- Any risk which is totally natural (could happen without human intervention), must be highly improbable, as we know we have been on this planet for a hundred thousand years without getting killed off. To estimate the probability of these risks, use Laplace’s Law of Succession.

- Risks which we cannot affect the probability of can be safely ignored. It does us little good to know that there is a 1% chance of doom next Thursday, if we can’t do anything about it.

Some specific risks which can be safely ignored:

- Particle accelerator accidents. We don’t yet know enough high-energy physics to say conclusively that a particle accelerator could never create a true vacuum, stable strangelet, or another universe-destroying particle. Luckily, we don’t have to; cosmic rays have been bombarding us for the past four billion years, with energies a million times higher than anything we can create in an accelerator. If it were possible to annihilate the planet with a high-energy particle collision, it would have happened already.

- The simulation gets shut down. The idea that “the universe is a simulation” is equally good at explaining every outcome- no matter what happens in the universe, you can concoct some reason why the simulators would engineer it. Which specific actions would make the universe safer from being shut down? We have no clue, and barring a revelation from On High, we have no way to find out. If we do try and take action to stop the universe from being shut down, it could just as easily make the risk worse.

- A long list of natural scenarios. To quote Nick Bostrom: “solar flares, supernovae, black hole explosions or mergers, gamma-ray bursts, galactic center outbursts, supervolcanos, loss of biodiversity, buildup of air pollution, gradual loss of human fertility, and various religious doomsday scenarios.” We can’t prevent most of these anyway, even if they were serious risks.

Some specific risks which should be given lower priority:

- Asteroid impact. This is a serious risk, but it still has a fairly low probability, on the order of one in 105 to 107 for something that would threaten the human species within the next century or so. Mitigation is also likely to be quite expensive compared to other risks.

- Global climate change. While this is fairly probable, the impact of it isn’t likely to be severe enough to qualify as an existential risk. The IPCC Fourth Assessement Report has concluded that it is “very likely” that there will be more heat waves and heavy rainfall events, while it is “likely” that there will be more droughts, hurricanes, and extreme high tides; these do not qualify as existential risks, or even anything particularly serious. We know from past temperature data that the Earth can warm by 6–9 C on a fairly short timescale, without causing a permanent collapse or even a mass extinction. Additionally, climate change has become a political problem, making it next to impossible to implement serious measures without a massive effort.

- Nuclear war is a special case, because although we can’t do much to prevent it, we can take action to prepare for it in case it does happen. We don’t even have to think about the best ways to prepare; there are already published, reviewed books detailing what can be done to seek safety in the event of a nuclear catastrophe. I firmly believe that every transhumanist organization should have a contingency plan in the event of nuclear war, economic depression, a conventional WWIII or another political disaster. This planet is too important to let it get blown up because the people saving it were “collateral damage”.

- Terrorism. It may be the bogeyman-of-the-decade, but terrorists are not going to deliberately destroy the Earth; terrorism is a political tool with political goals that require someone to be alive. While terrorists might do something stupid which results in an existential risk, “terrorism” isn’t a special case that we need to separately plan for; a virus, nanoreplicator or UFAI is just as deadly regardless of where it comes from.

Recently, our international spokesperson, Philippe Van Nedervelde, spoke to the deputy editor of Betterhumans, Parish Mozdzierz, on the Lifeboat Foundation, its goals and activities. Here is the first question:

Betterhumans: How did the formation of the Lifeboat Foundation come about?

Philippe Van Nedervelde: Lifeboat Foundation’s founder, Eric Klien, was shaken wide awake by 9/11. The new reality of what we call (exponentially accelerating) “Asymmetric Destructive Capability” (ADC) fully hit him: ever smaller groups of people can create ever more enormous amounts of damage. And all of this thanks to advances in technology. As a bracelet-wearing cryonicist, he knew of the potentials of nanotechnology (having attended MIT Nanotechnology Group meetings in the late 1980s), and that 9/11 was just a taste of things to come. Accordingly, the Lifeboat Foundation was incorporated within months of 9/11.

NASA’s Marshall Space Flight Center has designed a nuclear-warhead-carrying spacecraft, that would be boosted by the US agency’s proposed Ares V cargo launch vehicle, to deflect asteroids.

The Ares V launch vehicle is scheduled to first fly in 2018. It would launch 130 tons to LEO.

I welcome this study for providing a clearer analysis of the deflection options and the analyzing costs of searching for threatening asteroids.

The 8.9m (29ft)-long “Cradle” spacecraft would carry six 1,500kg (3,300lb) missile-like interceptor vehicles that would carry one 1.2MT B83 nuclear warhead each, with a total mass of 11,035kg.

99942 Apophis is a near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a relatively large probability that it would strike the Earth in 2029. It is 350 meters across and weighs about 46 million tons.

The study team assessed a series of approaches that could be used to divert a NEO potentially on a collision course with Earth. Nuclear explosives, as well as non-nuclear options, were assessed.
• Nuclear standoff explosions are assessed to be 10–100 times more effective than the non-nuclear alternatives analyzed in this study. Other techniques involving the surface or subsurface use of nuclear explosives may be more efficient, but they run an increased risk of fracturing the target NEO. They also carry higher development and operations risks.
• Non-nuclear kinetic impactors are the most mature approach and could be used in some deflection/mitigation scenarios, especially for NEOs that consist of a single small, solid body.
• “Slow push” mitigation techniques are the most expensive, have the lowest level of technical readiness, and their ability to both travel to and divert a threatening NEO would be limited unless mission durations of many years to decades are possible.
• 30–80 percent of potentially hazardous NEOs are in orbits that are beyond the capability of current or planned launch systems. Therefore, planetary gravity assist swingby trajectories or on-orbit assembly of modular propulsion systems may be needed to augment launch vehicle performance, if these objects need to be deflected.


This diagram shows that the nuclear options work better and can handle asteroids up to 950 meters in size


This is a table that shows that a performance index of 1 means a method was good enough to perform a successful deflection. Less than 1 means more launches are needed.

Cities that quickly closed schools and discouraged public gatherings had fewer deaths from the great flu pandemic in 1918 than cities that did not, researchers reported on Monday. Experts agree that a pandemic of some virus, most likely influenza, is almost 100 percent certain. What is not certain is when it will strike and which virus it will be.

In Kansas City, no more than 20 people could attend weddings or funerals. New York mandated staggered shifts at factories. In Seattle, the mayor told people to wear face masks.

No single action worked on its own, the researchers found, it was the combination of measures that saved lives. Peak death rates can be 50% to eight times lower. St. Louis authorities introduced “a broad series of measures designed to promote social distancing” as soon as flu showed up. Philadelphia downplayed the 1918 flu.

Philadelphia ended up with a peak death rate of 257 people per 100,000 population per week. St. Louis had just 31 per 100,000 at the peak.

No good vaccine would be available for months, and drugs that treat influenza are in very short supply.

So experts are looking at what they call non-pharmacologic interventions — ways to prevent infection without drugs. They hope this can buy time while companies make and distribute vaccines and drugs.

Because the virus is spread by small droplets passed within about three feet (1 meter) from person to person, keeping people apart is considered a possible strategy.

The U.S. government flu plan calls for similar measures, including allowing employees to stay home for weeks or even months, telecommuting and closing schools and perhaps large office buildings.

Using maps of population density, the researchers charted the places likely to suffer the most casualties from asteroids. As might be expected, countries with large coastal populations turned out to be most vulnerable, with China, Indonesia, India, Japan and the US in the top five spots.

The team focused on smaller asteroids because they hit the Earth more frequently. An asteroid a few hundred metres across hits the planet about once every 10,000 years, on average, while those larger than 1 kilometre hit only every 100,000 years or so. Small asteroids are also harder to spot. They considered a range of impact energies corresponding to asteroids between 100 and 500 metres across, striking with typical solar system speeds of about 20,000 kilometres per second.


Simulations show the asteroid impact locations that would produce the most casualties in red. The Pacific coast of Asia is a particularly deadly place for an asteroid to strike because of tsunamis, while a direct strike on some densely populated inland areas could also cause a heavy toll (Illustration: Nick Bailey et al/University of Southampton)

The US faced the worst potential economic losses, since it has a lot of infrastructure on coastlines facing two different oceans. China was second, followed by Sweden, Canada, and Japan.

The Lifeboat asteroid shield project helps to address these risks and Tsunami warning and response systems would also help mitigate loss of life from ocean impacts.

We welcome one of our most generous donors, Sergio M.L. Tarrero, to the Lifeboat Foundation staff as our International Director of Audiovisual Communications. Mr. Tarrero is currently working on a documentary on existential risk. His bio begins as follows:

Sergio Martínez de Lahidalga Tarrero, BSc, is a screenwriter and filmmaker deeply concerned with the institutionally mediated transmission of socially corrosive beliefs, thoughts, and behaviors. His abiding interest in the forces that drive people apart, particularly those deriving from religious doctrine, inspired him from a young age to ponder what it would take to move people to embrace the primacy of rational thinking over enculturated dogma. In Sergio’s view, an important idea to disseminate widely is that an ethical and contemplative life does not depend on theological postulates.

Read his whole bio here. In a world where the audiovisual medium is one of the most tangible and memorable forms of communication, Sergio’s filmmaking skills will contribute invaluably to the Lifeboat Foundation’s core mission.

DARPA (the defense advanced research projects agency) is the R&D arm of he US military for far-reaching future technology. What most people do not realize is how much revolutionary medical technology comes out of this agency’s military R&D programs. For those in need of background, you can read about the Army & DARPA’s future soldier Landwarrior program and its medtech offshoots as well as why DARPA does medical research and development that industry won’t. Fear of these future military technologies runs high with a push towards neural activation as a weapon, direct brain-computer interfaces, and drones. However, the new program has enormous potential for revolutionary medical progess as well.

It has been said technology is neutral, it is the application that is either good or evil. (It is worth a side-track to read a discussion on this concept)

The Areas of Focus for DARPA in 2007 and Forward Are:

  1. Chip-Scale Atomic Clock
  2. Global War on TerrorismUnmanned Air Vehicles
  3. Militarization of Space
  4. Supercomputer Systems
  5. Biological Warfare Defense
  6. Prosthetics
  7. Quantum Information Science
  8. Newton’s Laws for Biology
  9. Low-Cost Titanium
  10. Alternative Energy
  11. High Energy Liquid Laser Area Defense System

the potential for the destructive use of these technologies is obvious, for a a complete review of these projects and the beneficial medical applications of each visit docinthemachine.com

NASA estimates the cost to find at least 90 percent of the 20,000 potentially hazardous asteroids and comets by 2020 would be about $1 billion, according to a report NASA will release later this week. It would cost $300 million if a asteroid locating telescope was piggybacked on another vehicle. The report was previewed Monday at a Planetary Defense Conference in Washington.

The agency is already tracking bigger objects, at least 3,300 feet in diameter, that could wipe out most life on Earth, much like what is theorized to have happened to dinosaurs 65 million years ago. But even that search, which has spotted 769 asteroids and comets — none of which is on course to hit Earth — is behind schedule. It’s supposed to be complete by the end of next year.

A cheaper option would be to simply piggyback on other agencies’ telescopes, a cost of about $300 million, also rejected, Johnson said.

“The decision of the agency is we just can’t do anything about it right now,” he added.

Earth got a scare in 2004, when initial readings suggested an 885-foot asteroid called 99942 Apophis seemed to have a chance of hitting Earth in 2029. But more observations showed that wouldn’t happen. Scientists say there is a 1-in-45,000 chance that it could hit in 2036.

They think it would mostly likely strike the Pacific Ocean, which would cause a tsunami on the U.S. West Coast the size of the devastating 2004 Indian Ocean wave.

John Logsdon, space policy director at George Washington University, said a stepped-up search for such asteroids is needed.

“You can’t deflect them if you can’t find them,” Logsdon said. “And we can’t find things that can cause massive damage.”

Graduate student (University of Alabama Huntsville) Blake Anderton wrote his master’s thesis on “Application of Mode-locked lasers to asteroid characterization and mitigation.” Undergraduate Gordon Aiken won a prize at a recent student conference for his poster and presentation “Space positioned LIDAR system for characterization and mitigation of Near Earth Objects.” And members of the group are building a laser system “that is the grandfather of the laser that will push the asteroids,” Fork said.

Anderton’s mode locked lasers could characterize asteroids up to 1 AU away (1.5 x 10 to the 11 meters). Arecibo and other radar observatories can only detect objects up to 0.1 AU away, so in theory a laser would represent a vast improvement over radar.

A one page powerpoint describes their asteroid detection and deflection approach About 12 of the 1AU detection volumes (around the sun in the asteroid belt) would be needed to cover the main areas for near earth asteroids.

40KW femtosecond lasers could deflect an asteroid the size of Apophis (320meters, would hit with 880 megaton force) given one year of illumination and an early start in the trajectory.

Asteroid shields are a project of the Lifeboat Foundation

There are 67 kilowatt solid state lasers and modular laser systems & mirrors for reflecting lasers to achieve more laser power from smaller modules
