Kurzweil Press Release has Incorrect Date
A press release mentioning Ray Kurzweil is making the rounds on all the science sites now. It goes like this:
"BOSTON, Feb. 17 (UPI) -- A U.S. computer expert predicts computers will have the same intellectual capacity as humans by 2020.
Ray Kurzweil was one of 18 people chosen by the American Association for the Advancement of Science to speak on future technological challenges, The Independent reported. He said that in the future artificial intelligence will advance far beyond human intelligence.
"Three-dimensional, molecular computing will provide the hardware for human-level 'strong artificial intelligence' by the 2020s," he said. "The more important software insights will be gained in part from the reverse engineering of the human brain, a process well under way. Already, two dozen regions of the human brain have been modeled and simulated."
Kurzweil's predictions are based on the assumption that the "law of accelerating returns" will continue in the development of artificial intelligence. Computer chip power has doubled every two years for the past half-century as a function of the accelerating return principal."
The only problem -- this is totally incorrect! Kurzweil predicts human-level AI by 2029, not 2020. How did they let this one slip out there?
Interestingly enough, Kurzweil's predictions are stealing the spotlight of news coverage of this AAAS event. Here is a BBC article with the correct date, floating around at the same time as the press releases on the contradictory 2020 date.
The ubiquitous coverage of Kurzweil's predictions in the last few days is obvious evidence that futurists predicting artificial general intelligence within the next 20 or so years are anything but marginal.
As for me, I'm not sure when AI will come around, but it's better to assume sooner, and be prepared, than to assume later, and be caught blindsided.

Look to Inner, not Outer Space
From ScienceDaily, terrestrial planets form around most if not all nearby Sun-like stars. Not very surprising -- why would debris orbiting around other suns never form into terrestrial-sized balls? It seems as if the physics of other star systems would need to be fundamentally different to avoid that.
Contrary to some press releases on the subject, this discovery is evidence against the possibility of extraterrestrial life -- not for it. Now that this knowledge is in, the probability of life on other planets goes down, not up. Lots of Earth-like planets in this 10 billion-year old galaxy, not a peep from them.
The more terrestrial planets there are, the more likely it should be that at least one would harbor a K2 civilization, which would install solar panels in orbit around its Sun and leave a telltale infrared signature. Of the hundreds of thousands of stars we've studied using astronomical spectroscopy, none show the signs of an advanced civilization. All can be explained using modern theories of stellar evolution.
Perhaps distant planets harbor microbes or other simple life? If so, all the more reason to be uninterested in them. As we begin synthesizing life on our own, the diversity and elegance of the millions of new species we will create will far exceed anything a planet hundreds or thousands of light years away will offer.
What I want to do is dispel the mystery and wonder for the cosmos a little bit, and turn our attention towards humanity's awesome potential right here in the solar system. A civilization making full use of the solar system's resources could sustain more than a billion billion people, and be far greater than even the most fantastic depictions of galactic civilizations in fiction.
The era of discovering interesting complexity in the universe is coming to a close. Already, we have scientific names for most non-insect species larger than a few cm in diameter. Our planet is mapped to an accuracy greater than a pixel per meter, and we're doing the same for the Moon and Mars. The basic biochemistry of life is understood is exquisite detail. Although I'm sure there will be many other paradigm-changing scientific discoveries in the future, these will probably be in physics (a field involving many things very foreign to human experience) and psychology (the most complex known object in the universe is the human brain), not biology or chemistry or geography.
Instead of discovering new and interesting things, we have to invent them. This is already happening with online games like World of Warcraft and the upcoming Spore. We have to admit that the universe is in a relatively steady state on human timescales, and our ability to understand it exceeds its ability to generate new and interesting things on its own. If we want aliens, we have to custom-design genomes and use them to create new entities. If we want bizarre and wonderful exo-terrestrial landscapes, we have to build them in virtual reality. Because our voracious minds are already beginning to exhaust what the universe itself has to offer.
Evolutionary Psychology Master List
There needs to be a central resource of online papers containing evolutionary explanations for the various facets of human psychology. I began one on the SL4 wiki in 2002 or thereabouts, and thought I would call attention to it by reposting it here. If you want to make your own additions, the link is here.

Martin Rees on the Posthuman Era

On Edge.org, when asked "what have you changed your mind about?", British Astronomer Royal (and winner of the Lifeboat Foundation's 2004 Guardian Award) Martin Rees responded "We Should Take the ‘Posthuman’ Era Seriously":
"Human-induced changes are occurring with runaway speed. It’s hard to predict a mere century from now, because what will happen depends on us - this is the first century where humans can collectively transform, or even ravage, the entire biosphere. Humanity will soon itself be malleable, to an extent that’s qualitatively new in the history of our species. New drugs (and perhaps even implants into our brains) could change human character; the cyberworld has potential that is both exhilarating and frightening. We can’t confidently guess lifestyles, attitudes, social structures, or population sizes a century hence.
Indeed, it’s not even clear for how long our descendants would remain distinctively ‘human’. Darwin himself noted that “not one living species will transmit its unaltered likeness to a distant futurityâ€. Our own species will surely change and diversify faster than any predecessor—via human-induced modifications (whether intelligently-controlled or unintended), not by natural selection alone. Just how fast this could happen is disputed by experts, but the post-human era may be only centuries away.
These thoughts might seem irrelevant to practical discussions - and best left to speculative academics and cosmologists. I used to think this. But humans are now, individually and collectively, so greatly empowered by rapidly changing technology that we can, by design, or as unintended consequences - engender global changes that resonate for centuries. And, sometimes at least, policy-makers indeed think far ahead.
The global warming induced by fossil fuels burnt in the next fifty years could trigger gradual sea level rises that continue for a millennium or more. And in assessing sites for radioactive waste disposal, governments impose the requirements that they be secure for ten thousand years.
It’s real political progress that these long-term challenges are higher on the international agenda, and that planners seriously worry about what might happen more than a century hence.
But in such planning, we need to be mindful that it may not be people like us who confront the consequences of our actions today. We are custodians of a ‘posthuman’ future - here on Earth and perhaps beyond - that can’t just be left to writers of science fiction."
Astrophysicist, existential risk activist, transhumanism-aware thinker... what isn't there to like about this guy?
Six Physics “Supers” — Superconductivity and More
1. Superconductivity -- conducts electricity perfectly, magnetic fields are excluded from the interior of the object (Meissner effect). The soon-to-open Large Hadron Collider will use superconducting magnets to accelerate subatomic particles to 99% the speed of light. In the near future, superconducting materials will decrease the necessary size of large engines, such as those on aircraft carriers, by a factor of 3-4. Some scientists believe that the future discovery of a room-temperature superconductor will launch a new industrial revolution.

2. Superfluidity -- zero viscosity, zero entropy, infinite thermal conductivity, "creeps" up surfaces, shows quantum effects at the macroscopic level, such as behaving like a single "superatom". 645 gallons of superfluid helium were used to cool Gravity Probe B, an orbiter designed to test Einstein's theories about the curvature of spacetime. When rotated in a canister, a superfluid can only move at certain quantized, discrete speed levels.

3. Superlubricity -- practically zero friction observed in eggshell-shaped configurations of crystal. Might be used to create frictionless gears for nanomachines. Has been measured using the extremely sensitive Friction Force Microscope. The phenomenon of superlubricity is very new, only investigated seriously in the last few years. The image below shows regions on a crystal surface displaying superlubricity.

4. Supersonic -- faster than sound. "Hypersonic" refers to something traveling more than 5 times faster than sound, or Mach 5. The Earth's escape velocity is about Mach 24. When a plane or rocket exceeds the speed of sound, it produces the famous "sonic boom", which may exceed 200 decibels. A team of British engineers wants to build a commercial plane that travels at Mach 5, twice as fast as the Concorde. At that speed, the trip from Brussels to Australia would take less than five hours, passing over the North Pole. Scramjets have a top speed between Mach 12 and Mach 24.

5. Supercriticality -- a phase of matter that has properties of both a solid and gas. The picture below shows an aerogel, not a supercritical fluid itself but produced using one. Superfluids have zero surface tension, and are only created at high pressures. By tuning the pressure and temperature of a supercritical fluid, engineers can make it behave more like a liquid or a gas, including manipulating its ability to dissolve other materials. At the surface of Venus, temperature and pressure are sufficient to make the entire atmospheric base a supercritical fluid. Creating superfluid water requires a temperature of 704 °F and a pressure of 218 atmospheres.

6. Superluminal -- faster than light. In special relativity, while you cannot accelerate an object to the speed of light -- that requires infinite energy input -- nothing forbids the existence of something that always moves faster than light. Such a hypothetical particle is called a tachyon, and experiments are underway to find them. According to the theory of cosmic inflation, during the first fraction of a second of the universe's existence, space itself expanded many times faster than light. This is possible because nothing within space would actually move superluminally, just the spacetime fabric itself. In astronomy, certain phenomena such as relativistic jets appear to move superluminally due to an optical illusion.
Other supers in physics: supergravity, superstrings, supersolids.
21st Century Environmentalism
Eventually, a clear line will have to be drawn between the structures we value and those we don't. As our ability to convert disordered structures into ordered structures increases, we will eventually rearrange literally every atom on the planet into ordered structures.
This doesn't mean we turn the Earth into Coruscant. Just that natural structures will need express approval from conscious beings to keep on existing, and eventually nature will reflect all of what we want, and none of what we don't. For a moment, ignore differences among humans, and note that as matter-reshapers, our agendas are far more precisely aligned than any other optimization processes of which we are currently aware.
This conclusion is not the result of some techno-fantasy; it follows naturally from the fact that world population is increasing exponentially and our ability to manipulate matter is increasing as well. Already, the vast majority of the terrestrial vertebrate biomass consists of ourselves, our pets, and our meat animals. I'm not saying whether this is a good or bad thing, it's just a fact.
Humans have dug up gigatons of metals, sliced pathways through continents with canals, and replaced vast tracts of wildland with crop fields. These acts have been pursued because they represent greater value to humanity than the default condition.
Some environmentalists, the "deep greens", have the naive view that it's still possible to turn back the clock, go back to living as pastoralists, give up electricity and computers and factories. Some anti-environmentalists have a callous disregard for nature, viewing the world as nothing but a fruit waiting for us to disembowel it.
Most of the people that read my articles are probably somewhere in the middle, those who see the inevitability of population increase and technological transformation but do not consider it antithetical to preservation of the environment. This has been called the "bright green" wing of environmentalism, exemplified by websites such as WorldChanging and TreeHugger. The link between bright green environmentalism and transhumanism is intriguing, with visionaries such as Michael Graham Richard and Jamais Cascio straddling both worlds.
I believe typical bright green environmentalism is not radical enough. Given the technology, humans will choose to melt the ice at the poles for the vast tracts of land and sea it will make available, and simply deal with the consequences of sea level rise. I know it's blasphemy to say so, but the average global temperature really is way too cold, and most of Canada and Russia are just plain uninhabitable as a result. The world population is so small right now that we barely even notice. As I've argued before, the world can contain at least a hundred billion people, probably many more. To green the planet, we have to melt the ice and cultivate the deserts.
A single arcology with a footprint of only ten square miles could hold as many as a million people. All the obvious objections have been considered, and living in such an arcology would actually be quite pleasant, due to designs which would let in ample sunlight, and feature gardens intertwined with residential and commercial areas. Some arcologies might even be large enough to accommodate a small central rainforest. As an environmentalist, I believe we have a much better chance of preserving and expanding existing biodiversity if we take it along with us as we build upwards into the sky, creating a three-dimensional rather than just two-dimensional planetary ecology. With self-replicating robotics and synthetic biology workhorses at our command, we will turn the dead sands of the world's deserts into magnificent pyramids of silicon and glass, filled with every imaginable species of plant and animal, including ourselves.
I want to see the bright green movement get even brighter. Don't be afraid of complete human transformation of the biosphere. In the long term (or short term with the right technologies), it's inevitable -- the only question is whether we can do it in a way that takes the rest of the planet's biodiversity along with us. Technological development and environmentalism are not incompatible. In fact, environmentalists must embrace radical technological development or become obsolete.
List of Prominent Transhumanist-Receptive Thinkers, 2008
Here is a list of prominent people who take transhumanist ideas seriously enough to either discuss them or (more rarely) fear them. For those new to this blog, "transhumanism" is briefly defined in this post. By extension, people on this list have also been exposed to the idea of abrupt or accelerating technological change, though not necessarily technological change that "transcends stakeholder politics". The object of this list is to show that transhumanist topics have become acceptable for mainstream discussion in recent years.
1. Bill Clinton, former US President, who recommended The Age of Spiritual Machines to the audience at a talk at the Brainstorm 2001 conference. He called the book a "compelling view of the future" and lamented political leaders "out of touch" with the acceleration of technology.
2. Bill Gates, founder of Microsoft, who called Ray Kurzweil "the best person I know at predicting the future of artificial intelligence". Gates' writings on robotics indicate he expects massive technological change in the near future.
3. Richard A. Clarke, top US counter-terrorism adviser turned science fiction author. His 2007 novel Breakpoint takes a pro-transhumanist stance and mentions the movement by name.
4. Bill Joy, co-founder of Sun Microsystems, who expresses apprehension of transhumanist technologies in his landmark WIRED article, Why the future doesn't need us.
5. Marvin Minsky, co-founder of MIT's AI laboratory, who Isaac Asimov called one of the smart people he ever met. Minsky frequently discusses cryonics and human-level artificial intelligence.
6. Leon Kass, former chair of the President's Council on Bioethics from 2002–2005, whose seriousness and opposition towards transhumanism is outlined in the report Beyond Therapy, among other writings.
7. Stephen Hawking, theoretical physicist, who advocates genetic engineering of humans to prevent AIs from "taking over the world". In Scientific American, Hawking wrote an article promoting a transhumanist vision of the future.
8. David D. Friedman, anarcho-capitalist and law professor at Santa Clara University. His recent book Future Perfect deals with transhumanist themes, and he has been writing on the topics for over two decades.
9. Peter Thiel, co-founder of Paypal and early investor in Facebook. Thiel financed SIAI's Singularity Summit and has offered $3.5 million in matching funds to the Methuselah Foundation.
10. Steve Jurvetson, a leading Silicon Valley venture capitalist as Managing Director of Draper Fischer Jurvetson. Jurvetson's blog, the J-Curve, discusses accelerating change, superintelligence, synthetic life, biotechnology, nanotechnology, and other transhumanist themes.
There are many others, but ten should be enough for now. The point is: don't be afraid to bring up transhumanist topics with fellow intellectuals, at work or at home. The folks above probably all have a lot to lose, but they mention the issues with candor. By the same token, their high esteem may make others tolerant of quirky inclinations they may have, but the general response to these discussions has been positive, not dismissive.
