Paul J. Crutzen

Although this is the scenario we all hope (and work hard) to avoid — the consequences should be of interest to all who are interested in mitigation of the risk of mass extinction:

“WHEN Nobel prize-winning atmospheric chemist Paul Crutzen coined the word Anthropocene around 10 years ago, he gave birth to a powerful idea: that human activity is now affecting the Earth so profoundly that we are entering a new geological epoch.

The Anthropocene has yet to be accepted as a geological time period, but if it is, it may turn out to be the shortest — and the last. It is not hard to imagine the epoch ending just a few hundred years after it started, in an orgy of global warming and overconsumption.

Peter Garretson from the Lifeboat Advisory Board appears in the latest edition of New Scientist:

“IT LOOKS inconsequential enough, the faint little spot moving leisurely across the sky. The mountain-top telescope that just detected it is taking it very seriously, though. It is an asteroid, one never seen before. Rapid-survey telescopes discover thousands of asteroids every year, but there’s something very particular about this one. The telescope’s software decides to wake several human astronomers with a text message they hoped they would never receive. The asteroid is on a collision course with Earth. It is the size of a skyscraper and it’s big enough to raze a city to the ground. Oh, and it will be here in three days.

Far-fetched it might seem, but this scenario is all too plausible. Certainly it is realistic enough that the US air force recently brought together scientists, military officers and emergency-response officials for the first time to assess the nation’s ability to cope, should it come to pass.

Nature News reports of a growing concern over different standards for DNA screening and biosecurity:

“A standards war is brewing in the gene-synthesis industry. At stake is the way that the industry screens orders for hazardous toxins and genes, such as pieces of deadly viruses and bacteria. Two competing groups of companies are now proposing different sets of screening standards, and the results could be crucial for global biosecurity.

“If you have a company that persists with a lower standard, you can drag the industry down to a lower level,” says lawyer Stephen Maurer of the University of California, Berkeley, who is studying how the industry is developing responsible practices. “Now we have a standards war that is a race to the bottom.”

I recently began to worry that something/someone, some field, force, disease, prion, virus, bad luck and/or natural causes could threaten and perhaps destroy the most valuable entity in the universe, an entity more valuable than life itself. Consciousness. What good is life extension without conscious awareness? What is consciousness?

We know the brain works a lot like a computer, with neuron firings and synapses acting like bit states and switches. Brain-as-computer works very well to account for sensory processing, control of behavior, learning and other cognitive functions. These functions may in some cases be non-conscious, and other times associated with conscious experience and control. Scientists seek the distinction – the essential feature, or trick for consciousness.

Some suggest there is no trick, consciousness emerges as a by-product of cognitive computation among neurons. Others say we don’t know, that consciousness may indeed require some feature related to, but not quite the same as neuron-to-neuron cognition.

In either case, humans and other creatures could in principle become devoid of consciousness while maintaining cognitive behaviors, appearing more-or-less normal to outside observers. Such hypothetical non-conscious behaving entities are referred to in literature, films and philosophical texts as ‘zombies’. Philosopher David Chalmers introduced the philosophical zombie, a test case for whether or not consciousness is distinct from cognitive neurocomputation.

50 years ago Herman Khan coined the term in his book “On thermonuclear war”. His ideas are still important. Now we can read what he really said online. His main ideas are that DM is feasable, that it will cost around 10–100 billion USD, it will be much cheaper in the future and there are good rational reasons to built it as ultimate mean of defence, but better not to built it, because it will lead to DM-race between states with more and more dangerous and effective DM as outcome. And this race will not be stable, but provoking one side to strike first. This book and especially this chapter inspired “Dr. Strangelove” movie of Kubrick.

Abstract:

President Obama disbanded the President’s Council on Bioethics after it questioned his policy on embryonic stem cell research. White House press officer Reid Cherlin said that this was because the Council favored discussion over developing a shared consensus. This column lists a number of problems with Obama’s decision, and with his position on the most controversial bioethical issue of our time.

Bioethics and the End of Discussion

In early June, President Obama disbanded the President’s Council on Bioethics. According to White House press officer Reid Cherlin, this was because the Council was designed by the Bush administration to be “a philosophically leaning advisory group” that favored discussion over developing a shared consensus. http://www.nytimes.com/2009/06/18/us/politics/18ethics.html?_r=2

The Singularity Institute will be holding the fourth annual Singularity Summit in New York in October, featuring talks by Ray Kurzweil, David Chalmers, and Peter Thiel.

New York, NY (PRWEB) July 17, 2009 — The fourth annual Singularity Summit, a conference devoted to the better understanding of increasing intelligence and accelerating change, will be held in New York on October 3–4 in Kaufmann Hall at the historic 92nd St Y. The Summit brings together a visionary community to further dialogue and action on complex, long-term issues that are transforming the world.

Participants will hear talks from cutting-edge researchers and network with strategic business leaders. The world’s most eminent experts on forecasting, venture capital, emerging technologies, consciousness and life extension will present their unique perspectives on the future and how to get there. “The Singularity Summit is the premier conference on the Singularity,” says Ray Kurzweil, inventor of the CCD flatbed scanner and author of The Singularity is Near. “As we get closer to the Singularity, each year’s conference is better than the last.”

The Singularity Summit has previously been held in the San Francisco Bay Area, where it has been featured in numerous publications including the front page of the San Francisco Chronicle. It is hosted by the Singularity Institute, a 501©(3) nonprofit devoted to studying the benefits and risks of advanced technologies.
