Science Cult Ray Kurzweil's vision of a 'Singularity' has attracted some followers, but don't expect it anytime soon. The computer entrepreneur Ray Kurzweil says that we are on the verge of a "Singularity."

In physics, a "singularity" is an event or place, like the big bang or a black hole, where the laws of physics are stretched to the breaking point. Singularitarians (which some call themselves) have adopted the term to describe a radical transformation of consciousness that will result from breakthroughs in artificial intelligence as well as nanotechnology, biotechnology and neuroscience.

At first, Singularitarians say, we may become cyborgs, as WiFi-equipped brain chips, nanobots and genetic modifications soup up our intelligence, perception and memory. Eventually, we may abandon our flesh-and-blood selves entirely and transform our psyches into giant software programs. We will then "upload" ourselves into computers and dwell forever in cyberspace. Our transformation into immortal, God-like cyberbeings will supposedly take place not millennia or centuries from now but within the next few decades.

Kurzweil makes his case by showing graph after graph documenting the explosive progress over the past few decades in information technologies, including computers, the Internet, cell phones and so on. These advances are indeed astounding.

The problem is, some crucial scientific endeavours have made little or no progress over the past few decades.

For example, artificial-intelligence researchers, including Kurzweil himself, have invented programs that can read text, translate languages, recognize speech, interpret cardiograms and play championship-level chess. But they haven't come to close to creating the kind of artificial intelligence depicted in countless sci-fi films, from the cute R2D2 of Star Wars to the evil HAL of 2001: A Space Odyssey. Marvin Minsky, who served as an adviser for 2001, noted recently that computers still lack the common sense of a 4-year-old child; they can't even tell the difference between cats and dogs. "I wish I could tell you that we have intelligent machines," Minsky lamented, "but we don't."

Singularitarians such as Kurzweil insist that scientists will soon "reverse-engineer" the brain so that they understand exactly how it works. Many neuroscientists assume that, just as computers operate according to a machine code, so the brain's performance must depend on a "neural code"; this is the set of rules, syntax or algorithms that transforms electrical impulses emitted by brain cells into perceptions, memories, meanings, intentions. Researchers are trying to decode the brain by probing it with ever-more-powerful technologies, such as magnetic-resonance imaging, positron-emission tomography and microelectrodes.

Cracking the neural code should yield all sorts of benefits. First, the brain's programming tricks could be transferred to computers to make them smarter. Moreover, given the right interface, our brains and computers could communicate as readily as Macs and PCs. Eventually, our personal software could be extracted from our bodies for uploading into computers.

If a neural code exists, however, neuroscientists still have no idea what it is. Far from converging on a solution, scientists cannot agree whether information is represented primarily by signals from individual neurons, or brain cells, by oscillations of many neurons firing in tandem, by even higher-level waves of chaotic electrical activity sweeping through the brain or all of the above. This lack of understanding is reflected in the slow pace of research on so-called neural prostheses, which replace or supplement capacities lost because of damage to the nervous system.

The only truly successful neural prosthesis is the artificial cochlea. More than 100,000 hearing-impaired people have been equipped with those devices, which restore hearing by feeding signals from an external microphone to the auditory nerve.

Artificial retinas, light-sensitive chips that mimic the eye's signal-processing ability and stimulate the optical nerve or visual cortex, have been tested in a handful of blind subjects, but most have been able to see nothing more than phosphenes, or bright spots. A few paralyzed patients have learned to control a computer cursor "merely by thinking," as the media invariably put it, via implanted electrodes that pick up the patients' neural signals—but communicating that way remains slow and unreliable.

Kurzweil has excessive faith not only in artificial intelligence and neuroscience but also in biotechnology. In his book Fantastic Voyage: Live Long Enough to Live Forever, co-written with a physician, he claims that the Human Genome Project and related advances will soon yield cures both for specific diseases and even aging itself. The identification of specific genes underpinning inherited disease—such as Huntington's disease and immune-deficiency syndrome—has inspired researchers to devise therapies to correct the genetic malformations.

So far, scientists have carried out hundreds of clinical trials of gene therapy, and not one has been an unqualified success. The treatments have sickened some patients and even killed them. The record of cancer treatment is also dismal. Since 1971, when President Richard Nixon declared a "war on cancer," the United States has spent more than $70 billion on research, and the annual budget for the National Cancer Institute has increased by a factor of 20, from $250 million to $5 billion. Scientists have gained a much better understanding of the molecular and genetic underpinnings of cancer, but this knowledge has not yielded significant improvements in treatments. Overall cancer mortality rates in the U.S. actually rose from 1971 until the early 1990s before declining slightly over the last decade or so—largely because of a decrease in the number of male smokers.

Given the track record of treatments for inherited diseases and cancer, proclamations about the imminence of immortality are absurd.

Part of me—the part that thrilled at prospects for artificial intelligence almost 30 years ago—finds Kurzweil's prophesies highly entertaining. He raises lots of provocative questions: What would be like to be immortal? To have an IQ of 1,000? To exist not as a doomed, flesh-and-blood creature but as a piece of software that can keep redesigning itself and merging with other programs?

But another part of me—the grown-up, responsible part—worries that so many people, smart people, are taking Kurzweil's sci-fi fantasies seriously. The last thing humanity needs right now is an apocalyptic cult masquerading as science.

Michio Kaku: If You Can’t Beat the Singularity, Join It

December 15th, 2010 by Aaron Saenz

Michio Kaku joins The Singularity

Are you worried about the coming robot apocalypse? Does research into artificial general intelligence freak you out? Do you look at computers and start dreading for the safety of your children? If so, world renowned physicist and science champion Michio Kaku has a message for you: instead of fearing technology, humanity should learn how to become part of it. Kaku hosts a great TV show called Sci Fi Science wherein he explores some of the amazing technologies being developed today, and the out-of-this-world consequences they could bring tomorrow. Recently, he took a look at the Technological Singularity, which as he puts it will be “a time when computer power grows without limit, surpassing human intelligence, sweeping aside everything in its path.” Sounds scary, huh? Well, after talking to experts around the world, Kaku decides there’s only one reasonable way to deal with the Singularity: join it. By merging with computers, humanity will not only preserve itself, it will expand into realms it cannot comprehend in the present. Watch clips from Kaku’s Singularity episode in the video above. By the end Kaku is openly recruiting us to join him in embracing the machine.


Michio Kaku is one of the most famous modern day presenters in science. He’s authored several best sellers, hosts two radio programs, has the Sci Fi Science TV show (now in its second season), and writes a blog on BigThink. As we’ve shown in the past, he seems to delight in answering questions from average readers and viewers, and no subject seems too far-fetched for him to consider and explain. It’s only fitting then that Kaku take a long look at the Singularity and consider the implications of exponential growth in artificial intelligence. While Kaku doesn’t espouse as optimistic approach to the subject as many others, he does end up with a very positive outlook on what the growth of AI could mean for humanity. I tend to share his view. Accelerating technology is only scary when you view it as separate from ourselves. Once you realize that we are already increasing the ways we incorporate it into our everyday lives (how long do you go between using your phone, the internet, or computer?) continuing along that path starts to make sense. Don’t fear the machine conquering humanity. The machine will become one with humanity.
