How the Internet Gets Inside Us : The New Yorker - 0 views

  • N.Y.U. professor Clay Shirky—the author of “Cognitive Surplus” and many articles and blog posts proclaiming the coming of the digital millennium—is the breeziest and seemingly most self-confident
  • Shirky believes that we are on the crest of an ever-surging wave of democratized information: the Gutenberg printing press produced the Reformation, which produced the Scientific Revolution, which produced the Enlightenment, which produced the Internet, each move more liberating than the one before.
  • The idea, for instance, that the printing press rapidly gave birth to a new order of information, democratic and bottom-up, is a cruel cartoon of the truth. If the printing press did propel the Reformation, one of the biggest ideas it propelled was Luther’s newly invented absolutist anti-Semitism. And what followed the Reformation wasn’t the Enlightenment, a new era of openness and freely disseminated knowledge. What followed the Reformation was, actually, the Counter-Reformation, which used the same means—i.e., printed books—to spread ideas about what jerks the reformers were, and unleashed a hundred years of religious warfare.

  • If ideas of democracy and freedom emerged at the end of the printing-press era, it wasn’t by some technological logic but because of parallel inventions, like the ideas of limited government and religious tolerance, very hard won from history.
  • As Andrew Pettegree shows in his fine new study, “The Book in the Renaissance,” the mainstay of the printing revolution in seventeenth-century Europe was not dissident pamphlets but royal edicts, printed by the thousand: almost all the new media of that day were working, in essence, for kinglouis.gov.
  • Even later, full-fledged totalitarian societies didn’t burn books. They burned some books, while keeping the printing presses running off such quantities that by the mid-fifties Stalin was said to have more books in print than Agatha Christie.
  • Many of the more knowing Never-Betters turn for cheer not to messy history and mixed-up politics but to psychology—to the actual expansion of our minds.
  • The argument, advanced in Andy Clark’s “Supersizing the Mind” and in Robert K. Logan’s “The Sixth Language,” begins with the claim that cognition is not a little processing program that takes place inside your head, Robby the Robot style. It is a constant flow of information, memory, plans, and physical movements, in which as much thinking goes on out there as in here. If television produced the global village, the Internet produces the global psyche: everyone keyed in like a neuron, so that to the eyes of a watching Martian we are really part of a single planetary brain. Contraptions don’t change consciousness; contraptions are part of consciousness. We may not act better than we used to, but we sure think differently than we did.
  • Cognitive entanglement, after all, is the rule of life. My memories and my wife’s intermingle. When I can’t recall a name or a date, I don’t look it up; I just ask her. Our machines, in this way, become our substitute spouses and plug-in companions.
  • But, if cognitive entanglement exists, so does cognitive exasperation. Husbands and wives deny each other’s memories as much as they depend on them. That’s fine until it really counts (say, in divorce court). In a practical, immediate way, one sees the limits of the so-called “extended mind” clearly in the mob-made Wikipedia, the perfect product of that new vast, supersized cognition: when there’s easy agreement, it’s fine, and when there’s widespread disagreement on values or facts, as with, say, the origins of capitalism, it’s fine, too; you get both sides. The trouble comes when one side is right and the other side is wrong and doesn’t know it. The Shakespeare authorship page and the Shroud of Turin page are scenes of constant conflict and are packed with unreliable information. Creationists crowd cyberspace every bit as effectively as evolutionists, and extend their minds just as fully. Our trouble is not the over-all absence of smartness but the intractable power of pure stupidity, and no machine, or mind, seems extended enough to cure that.
  • Nicholas Carr, in “The Shallows,” William Powers, in “Hamlet’s BlackBerry,” and Sherry Turkle, in “Alone Together,” all bear intimate witness to a sense that the newfound land, the ever-present BlackBerry-and-instant-message world, is one whose price, paid in frayed nerves and lost reading hours and broken attention, is hardly worth the gains it gives us. “The medium does matter,” Carr has written. “As a technology, a book focuses our attention, isolates us from the myriad distractions that fill our everyday lives. A networked computer does precisely the opposite. It is designed to scatter our attention. . . . Knowing that the depth of our thought is tied directly to the intensity of our attentiveness, it’s hard not to conclude that as we adapt to the intellectual environment of the Net our thinking becomes shallower.
  • Carr is most concerned about the way the Internet breaks down our capacity for reflective thought.
  • Powers’s reflections are more family-centered and practical. He recounts, very touchingly, stories of family life broken up by the eternal consultation of smartphones and computer monitors
  • He then surveys seven Wise Men—Plato, Thoreau, Seneca, the usual gang—who have something to tell us about solitude and the virtues of inner space, all of it sound enough, though he tends to overlook the significant point that these worthies were not entirely in favor of the kinds of liberties that we now take for granted and that made the new dispensation possible.
  • Similarly, Nicholas Carr cites Martin Heidegger for having seen, in the mid-fifties, that new technologies would break the meditational space on which Western wisdoms depend. Since Heidegger had not long before walked straight out of his own meditational space into the arms of the Nazis, it’s hard to have much nostalgia for this version of the past. One feels the same doubts when Sherry Turkle, in “Alone Together,” her touching plaint about the destruction of the old intimacy-reading culture by the new remote-connection-Internet culture, cites studies that show a dramatic decline in empathy among college students, who apparently are “far less likely to say that it is valuable to put oneself in the place of others or to try and understand their feelings.” What is to be done?
  • Among Ever-Wasers, the Harvard historian Ann Blair may be the most ambitious. In her book “Too Much to Know: Managing Scholarly Information Before the Modern Age,” she makes the case that what we’re going through is like what others went through a very long while ago. Against the cartoon history of Shirky or Tooby, Blair argues that the sense of “information overload” was not the consequence of Gutenberg but already in place before printing began. She wants us to resist “trying to reduce the complex causal nexus behind the transition from Renaissance to Enlightenment to the impact of a technology or any particular set of ideas.” Anyway, the crucial revolution was not of print but of paper: “During the later Middle Ages a staggering growth in the production of manuscripts, facilitated by the use of paper, accompanied a great expansion of readers outside the monastic and scholastic contexts.” For that matter, our minds were altered less by books than by index slips. Activities that seem quite twenty-first century, she shows, began when people cut and pasted from one manuscript to another; made aggregated news in compendiums; passed around précis. “Early modern finding devices” were forced into existence: lists of authorities, lists of headings.
  • Everyone complained about what the new information technologies were doing to our minds. Everyone said that the flood of books produced a restless, fractured attention. Everyone complained that pamphlets and poems were breaking kids’ ability to concentrate, that big good handmade books were ignored, swept aside by printed works that, as Erasmus said, “are foolish, ignorant, malignant, libelous, mad.” The reader consulting a card catalogue in a library was living a revolution as momentous, and as disorienting, as our own.
  • The book index was the search engine of its era, and needed to be explained at length to puzzled researchers
  • That uniquely evil and necessary thing the comprehensive review of many different books on a related subject, with the necessary oversimplification of their ideas that it demanded, was already around in 1500, and already being accused of missing all the points. In the period when many of the big, classic books that we no longer have time to read were being written, the general complaint was that there wasn’t enough time to read big, classic books.
  • at any given moment, our most complicated machine will be taken as a model of human intelligence, and whatever media kids favor will be identified as the cause of our stupidity. When there were automatic looms, the mind was like an automatic loom; and, since young people in the loom period liked novels, it was the cheap novel that was degrading our minds. When there were telephone exchanges, the mind was like a telephone exchange, and, in the same period, since the nickelodeon reigned, moving pictures were making us dumb. When mainframe computers arrived and television was what kids liked, the mind was like a mainframe and television was the engine of our idiocy. Some machine is always showing us Mind; some entertainment derived from the machine is always showing us Non-Mind.

Paris Review - The Grandmaster Hoax, Lincoln Michel - 0 views

  • The Turk was a hoax, although he was incorrect about the workings of the trick. Rather than a man hidden inside the wooden body, the seemingly exposed innards of the cabinet did not extend all the way back. A hidden grandmaster slid around when the cabinet doors were opened and closed. The concealed grandmaster controlled The Turk’s movements and followed the game’s action through a clever arrangement of magnets and strings.

Digital Domain - Computers at Home - Educational Hope vs. Teenage Reality - NYTimes.com - 0 views

  • MIDDLE SCHOOL students are champion time-wasters. And the personal computer may be the ultimate time-wasting appliance.
  • there is an automatic inclination to think of the machine in its most idealized form, as the Great Equalizer. In developing countries, computers are outfitted with grand educational hopes, like those that animate the One Laptop Per Child initiative, which was examined in this space in April.
  • Economists are trying to measure a home computer’s educational impact on schoolchildren in low-income households. Taking widely varying routes, they are arriving at similar conclusions: little or no educational benefit is found. Worse, computers seem to have further separated children in low-income households, whose test scores often decline after the machine arrives, from their more privileged counterparts.

  • Professor Malamud and his collaborator, Cristian Pop-Eleches, an assistant professor of economics at Columbia University, did their field work in Romania in 2009, where the government invited low-income families to apply for vouchers worth 200 euros (then about $300) that could be used for buying a home computer. The program provided a control group: the families who applied but did not receive a voucher.
  • the professors report finding “strong evidence that children in households who won a voucher received significantly lower school grades in math, English and Romanian.” The principal positive effect on the students was improved computer skills.
  • few children whose families obtained computers said they used the machines for homework. What they were used for — daily — was playing games.
  • negative effect on test scores was not universal, but was largely confined to lower-income households, in which, the authors hypothesized, parental supervision might be spottier, giving students greater opportunity to use the computer for entertainment unrelated to homework and reducing the amount of time spent studying.
  • The North Carolina study suggests the disconcerting possibility that home computers and Internet access have such a negative effect only on some groups and end up widening achievement gaps between socioeconomic groups. The expansion of broadband service was associated with a pronounced drop in test scores for black students in both reading and math, but no effect on the math scores and little on the reading scores of other students.

Balderdash: Links - 26th March 2012 - 0 views

  •  
    "We are in the midst of a technological upheaval; and financial rewards are flowing to the elites who create and control the new machines. Almost everybody else is threatened - including sophisticated bank executives at Citi and WellPoint's healthcare analysts... Even if displaced workers do find jobs, will these jobs be dignified? A society divided between master-programmers and servants may not appeal to the servants, who will be the majority. But neo-Marxist visions of burger flippers on the barricades seem a touch too paranoid. In the 19th century, the shift from farm to factory was decried as dehumanising. But the supposedly alienated proletariat soon morphed into proud welders and machinists and today it is the decline of factories that is perceived as a problem. The lesson is that attitudes adjust and job status is elastic. There may be real unhappiness during the adjustment phase, but eventually the nannies of yesterday will be the respected childcare professionals of tomorrow. Cooks will turn into executive chefs. And so, in the last analysis, Watson's most enduring impact will be to accentuate the trade-off between equity and growth"

Drone journalism takes off - ABC News (Australian Broadcasting Corporation) - 0 views

  • Instead of acquiring military-style multi-million dollar unmanned aerial vehicles the size of small airliners, the media is beginning to go micro, exploiting rapid advances in technology by deploying small toy-like UAVs to get the story.
  • Last November, drone journalism hit the big time after a Polish activist launched a small craft with four helicopter-like rotors called a quadrocopter. He flew the drone low over riot police lines to record a violent demonstration in Warsaw. The pictures were extraordinarily different from run-of-the-mill protest coverage.Posted online, the images went viral. More significantly, this birds-eye view clip found its way onto the bulletins and web pages of mainstream media.
  • Drone Journalism Lab, a research project to determine the viability of remote airborne media.
  •  
    Drones play an increasing and controversial role in modern warfare. From Afghanistan and Pakistan to Iran and Yemen, they have become a ubiquitous symbol of Washington's war on terrorism. Critics point to the mounting drone-induced death toll as evidence that machines, no matter how sophisticated, cannot discriminate between combatants and innocent bystanders. Now drones are starting to fly into a more peaceful, yet equally controversial role in the media. Rapid technological advances in low-cost aerial platforms herald the age of drone journalism. But it will not be all smooth flying: this new media tool can expect to be buffeted by the issues of safety, ethics and legality.

The internet: is it changing the way we think? | Technology | The Observer - 0 views

  • American magazine the Atlantic lobs an intellectual grenade into our culture. In the summer of 1945, for example, it published an essay by the Massachusetts Institute of Technology (MIT) engineer Vannevar Bush entitled "As We May Think". It turned out to be the blueprint for what eventually emerged as the world wide web. Two summers ago, the Atlantic published an essay by Nicholas Carr, one of the blogosphere's most prominent (and thoughtful) contrarians, under the headline "Is Google Making Us Stupid?".
  • Carr wrote, "I've had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn't going – so far as I can tell – but it's changing. I'm not thinking the way I used to think. I can feel it most strongly when I'm reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument and I'd spend hours strolling through long stretches of prose. That's rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I'm always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle."
  • Carr's target was not really the world's leading search engine, but the impact that ubiquitous, always-on networking is having on our cognitive processes. His argument was that our deepening dependence on networking technology is indeed changing not only the way we think, but also the structure of our brains.
  • ...9 more annotations...
  • Carr's article touched a nerve and has provoked a lively, ongoing debate on the net and in print (he has now expanded it into a book, The Shallows: What the Internet Is Doing to Our Brains). This is partly because he's an engaging writer who has vividly articulated the unease that many adults feel about the way their modi operandi have changed in response to ubiquitous networking.
  • Who bothers to write down or memorise detailed information any more, for example, when they know that Google will always retrieve it if it's needed again? The web has become, in a way, a global prosthesis for our collective memory.
  • easy to dismiss Carr's concern as just the latest episode of the moral panic that always accompanies the arrival of a new communications technology. People fretted about printing, photography, the telephone and television in analogous ways. It even bothered Plato, who argued that the technology of writing would destroy the art of remembering.
  • many commentators who accept the thrust of his argument seem not only untroubled by its far-reaching implications but are positively enthusiastic about them. When the Pew Research Centre's Internet & American Life project asked its panel of more than 370 internet experts for their reaction, 81% of them agreed with the proposition that "people's use of the internet has enhanced human intelligence".
  • As a writer, thinker, researcher and teacher, what I can attest to is that the internet is changing our habits of thinking, which isn't the same thing as changing our brains. The brain is like any other muscle – if you don't stretch it, it gets both stiff and flabby. But if you exercise it regularly, and cross-train, your brain will be flexible, quick, strong and versatile.
  • he internet is analogous to a weight-training machine for the brain, as compared with the free weights provided by libraries and books. Each method has its advantage, but used properly one works you harder. Weight machines are directive and enabling: they encourage you to think you've worked hard without necessarily challenging yourself. The internet can be the same: it often tells us what we think we know, spreading misinformation and nonsense while it's at it. It can substitute surface for depth, imitation for originality, and its passion for recycling would surpass the most committed environmentalist.
  • I've seen students' thinking habits change dramatically: if information is not immediately available via a Google search, students are often stymied. But of course what a Google search provides is not the best, wisest or most accurate answer, but the most popular one.
  • But knowledge is not the same thing as information, and there is no question to my mind that the access to raw information provided by the internet is unparalleled and democratising. Admittance to elite private university libraries and archives is no longer required, as they increasingly digitise their archives. We've all read the jeremiads that the internet sounds the death knell of reading, but people read online constantly – we just call it surfing now. What they are reading is changing, often for the worse; but it is also true that the internet increasingly provides a treasure trove of rare books, documents and images, and as long as we have free access to it, then the internet can certainly be a force for education and wisdom, and not just for lies, damned lies, and false statistics.
  • In the end, the medium is not the message, and the internet is just a medium, a repository and an archive. Its greatest virtue is also its greatest weakness: it is unselective. This means that it is undiscriminating, in both senses of the word. It is indiscriminate in its principles of inclusion: anything at all can get into it. But it also – at least so far – doesn't discriminate against anyone with access to it. This is changing rapidly, of course, as corporations and governments seek to exert control over it. Knowledge may not be the same thing as power, but it is unquestionably a means to power. The question is, will we use the internet's power for good, or for evil? The jury is very much out. The internet itself is disinterested: but what we use it for is not.
  •  
    The internet: is it changing the way we think? American writer Nicholas Carr's claim that the internet is not only shaping our lives but physically altering our brains has sparked a lively and ongoing debate, says John Naughton. Below, a selection of writers and experts offer their opinion

How We Know by Freeman Dyson | The New York Review of Books - 0 views

  • Another example illustrating the central dogma is the French optical telegraph.
  • The telegraph was an optical communication system with stations consisting of large movable pointers mounted on the tops of sixty-foot towers. Each station was manned by an operator who could read a message transmitted by a neighboring station and transmit the same message to the next station in the transmission line.
  • The distance between neighbors was about seven miles. Along the transmission lines, optical messages in France could travel faster than drum messages in Africa. When Napoleon took charge of the French Republic in 1799, he ordered the completion of the optical telegraph system to link all the major cities of France from Calais and Paris to Toulon and onward to Milan. The telegraph became, as Claude Chappe had intended, an important instrument of national power. Napoleon made sure that it was not available to private users.
  • ...27 more annotations...
  • Unlike the drum language, which was based on spoken language, the optical telegraph was based on written French. Chappe invented an elaborate coding system to translate written messages into optical signals. Chappe had the opposite problem from the drummers. The drummers had a fast transmission system with ambiguous messages. They needed to slow down the transmission to make the messages unambiguous. Chappe had a painfully slow transmission system with redundant messages. The French language, like most alphabetic languages, is highly redundant, using many more letters than are needed to convey the meaning of a message. Chappe’s coding system allowed messages to be transmitted faster. Many common phrases and proper names were encoded by only two optical symbols, with a substantial gain in speed of transmission. The composer and the reader of the message had code books listing the message codes for eight thousand phrases and names. For Napoleon it was an advantage to have a code that was effectively cryptographic, keeping the content of the messages secret from citizens along the route.
  • After these two historical examples of rapid communication in Africa and France, the rest of Gleick’s book is about the modern development of information technolog
  • The modern history is dominated by two Americans, Samuel Morse and Claude Shannon. Samuel Morse was the inventor of Morse Code. He was also one of the pioneers who built a telegraph system using electricity conducted through wires instead of optical pointers deployed on towers. Morse launched his electric telegraph in 1838 and perfected the code in 1844. His code used short and long pulses of electric current to represent letters of the alphabet.
  • Morse was ideologically at the opposite pole from Chappe. He was not interested in secrecy or in creating an instrument of government power. The Morse system was designed to be a profit-making enterprise, fast and cheap and available to everybody. At the beginning the price of a message was a quarter of a cent per letter. The most important users of the system were newspaper correspondents spreading news of local events to readers all over the world. Morse Code was simple enough that anyone could learn it. The system provided no secrecy to the users. If users wanted secrecy, they could invent their own secret codes and encipher their messages themselves. The price of a message in cipher was higher than the price of a message in plain text, because the telegraph operators could transcribe plain text faster. It was much easier to correct errors in plain text than in cipher.
  • Claude Shannon was the founding father of information theory. For a hundred years after the electric telegraph, other communication systems such as the telephone, radio, and television were invented and developed by engineers without any need for higher mathematics. Then Shannon supplied the theory to understand all of these systems together, defining information as an abstract quantity inherent in a telephone message or a television picture. Shannon brought higher mathematics into the game.
  • When Shannon was a boy growing up on a farm in Michigan, he built a homemade telegraph system using Morse Code. Messages were transmitted to friends on neighboring farms, using the barbed wire of their fences to conduct electric signals. When World War II began, Shannon became one of the pioneers of scientific cryptography, working on the high-level cryptographic telephone system that allowed Roosevelt and Churchill to talk to each other over a secure channel. Shannon’s friend Alan Turing was also working as a cryptographer at the same time, in the famous British Enigma project that successfully deciphered German military codes. The two pioneers met frequently when Turing visited New York in 1943, but they belonged to separate secret worlds and could not exchange ideas about cryptography.
  • In 1945 Shannon wrote a paper, “A Mathematical Theory of Cryptography,” which was stamped SECRET and never saw the light of day. He published in 1948 an expurgated version of the 1945 paper with the title “A Mathematical Theory of Communication.” The 1948 version appeared in the Bell System Technical Journal, the house journal of the Bell Telephone Laboratories, and became an instant classic. It is the founding document for the modern science of information. After Shannon, the technology of information raced ahead, with electronic computers, digital cameras, the Internet, and the World Wide Web.
  • According to Gleick, the impact of information on human affairs came in three installments: first the history, the thousands of years during which people created and exchanged information without the concept of measuring it; second the theory, first formulated by Shannon; third the flood, in which we now live
  • The event that made the flood plainly visible occurred in 1965, when Gordon Moore stated Moore’s Law. Moore was an electrical engineer, founder of the Intel Corporation, a company that manufactured components for computers and other electronic gadgets. His law said that the price of electronic components would decrease and their numbers would increase by a factor of two every eighteen months. This implied that the price would decrease and the numbers would increase by a factor of a hundred every decade. Moore’s prediction of continued growth has turned out to be astonishingly accurate during the forty-five years since he announced it. In these four and a half decades, the price has decreased and the numbers have increased by a factor of a billion, nine powers of ten. Nine powers of ten are enough to turn a trickle into a flood.
  • Gordon Moore was in the hardware business, making hardware components for electronic machines, and he stated his law as a law of growth for hardware. But the law applies also to the information that the hardware is designed to embody. The purpose of the hardware is to store and process information. The storage of information is called memory, and the processing of information is called computing. The consequence of Moore’s Law for information is that the price of memory and computing decreases and the available amount of memory and computing increases by a factor of a hundred every decade. The flood of hardware becomes a flood of information.
  • In 1949, one year after Shannon published the rules of information theory, he drew up a table of the various stores of memory that then existed. The biggest memory in his table was the US Library of Congress, which he estimated to contain one hundred trillion bits of information. That was at the time a fair guess at the sum total of recorded human knowledge. Today a memory disc drive storing that amount of information weighs a few pounds and can be bought for about a thousand dollars. Information, otherwise known as data, pours into memories of that size or larger, in government and business offices and scientific laboratories all over the world. Gleick quotes the computer scientist Jaron Lanier describing the effect of the flood: “It’s as if you kneel to plant the seed of a tree and it grows so fast that it swallows your whole town before you can even rise to your feet.”
  • On December 8, 2010, Gleick published on the The New York Review’s blog an illuminating essay, “The Information Palace.” It was written too late to be included in his book. It describes the historical changes of meaning of the word “information,” as recorded in the latest quarterly online revision of the Oxford English Dictionary. The word first appears in 1386 a parliamentary report with the meaning “denunciation.” The history ends with the modern usage, “information fatigue,” defined as “apathy, indifference or mental exhaustion arising from exposure to too much information.”
  • The consequences of the information flood are not all bad. One of the creative enterprises made possible by the flood is Wikipedia, started ten years ago by Jimmy Wales. Among my friends and acquaintances, everybody distrusts Wikipedia and everybody uses it. Distrust and productive use are not incompatible. Wikipedia is the ultimate open source repository of information. Everyone is free to read it and everyone is free to write it. It contains articles in 262 languages written by several million authors. The information that it contains is totally unreliable and surprisingly accurate. It is often unreliable because many of the authors are ignorant or careless. It is often accurate because the articles are edited and corrected by readers who are better informed than the authors
  • Jimmy Wales hoped when he started Wikipedia that the combination of enthusiastic volunteer writers with open source information technology would cause a revolution in human access to knowledge. The rate of growth of Wikipedia exceeded his wildest dreams. Within ten years it has become the biggest storehouse of information on the planet and the noisiest battleground of conflicting opinions. It illustrates Shannon’s law of reliable communication. Shannon’s law says that accurate transmission of information is possible in a communication system with a high level of noise. Even in the noisiest system, errors can be reliably corrected and accurate information transmitted, provided that the transmission is sufficiently redundant. That is, in a nutshell, how Wikipedia works.
  • The information flood has also brought enormous benefits to science. The public has a distorted view of science, because children are taught in school that science is a collection of firmly established truths. In fact, science is not a collection of truths. It is a continuing exploration of mysteries. Wherever we go exploring in the world around us, we find mysteries. Our planet is covered by continents and oceans whose origin we cannot explain. Our atmosphere is constantly stirred by poorly understood disturbances that we call weather and climate. The visible matter in the universe is outweighed by a much larger quantity of dark invisible matter that we do not understand at all. The origin of life is a total mystery, and so is the existence of human consciousness. We have no clear idea how the electrical discharges occurring in nerve cells in our brains are connected with our feelings and desires and actions.
  • Even physics, the most exact and most firmly established branch of science, is still full of mysteries. We do not know how much of Shannon’s theory of information will remain valid when quantum devices replace classical electric circuits as the carriers of information. Quantum devices may be made of single atoms or microscopic magnetic circuits. All that we know for sure is that they can theoretically do certain jobs that are beyond the reach of classical devices. Quantum computing is still an unexplored mystery on the frontier of information theory. Science is the sum total of a great multitude of mysteries. It is an unending argument between a great multitude of voices. It resembles Wikipedia much more than it resembles the Encyclopaedia Britannica.
  • The rapid growth of the flood of information in the last ten years made Wikipedia possible, and the same flood made twenty-first-century science possible. Twenty-first-century science is dominated by huge stores of information that we call databases. The information flood has made it easy and cheap to build databases. One example of a twenty-first-century database is the collection of genome sequences of living creatures belonging to various species from microbes to humans. Each genome contains the complete genetic information that shaped the creature to which it belongs. The genome data-base is rapidly growing and is available for scientists all over the world to explore. Its origin can be traced to the year 1939, when Shannon wrote his Ph.D. thesis with the title “An Algebra for Theoretical Genetics.
  • Shannon was then a graduate student in the mathematics department at MIT. He was only dimly aware of the possible physical embodiment of genetic information. The true physical embodiment of the genome is the double helix structure of DNA molecules, discovered by Francis Crick and James Watson fourteen years later. In 1939 Shannon understood that the basis of genetics must be information, and that the information must be coded in some abstract algebra independent of its physical embodiment. Without any knowledge of the double helix, he could not hope to guess the detailed structure of the genetic code. He could only imagine that in some distant future the genetic information would be decoded and collected in a giant database that would define the total diversity of living creatures. It took only sixty years for his dream to come true.
  • In the twentieth century, genomes of humans and other species were laboriously decoded and translated into sequences of letters in computer memories. The decoding and translation became cheaper and faster as time went on, the price decreasing and the speed increasing according to Moore’s Law. The first human genome took fifteen years to decode and cost about a billion dollars. Now a human genome can be decoded in a few weeks and costs a few thousand dollars. Around the year 2000, a turning point was reached, when it became cheaper to produce genetic information than to understand it. Now we can pass a piece of human DNA through a machine and rapidly read out the genetic information, but we cannot read out the meaning of the information. We shall not fully understand the information until we understand in detail the processes of embryonic development that the DNA orchestrated to make us what we are.
  • The explosive growth of information in our human society is a part of the slower growth of ordered structures in the evolution of life as a whole. Life has for billions of years been evolving with organisms and ecosystems embodying increasing amounts of information. The evolution of life is a part of the evolution of the universe, which also evolves with increasing amounts of information embodied in ordered structures, galaxies and stars and planetary systems. In the living and in the nonliving world, we see a growth of order, starting from the featureless and uniform gas of the early universe and producing the magnificent diversity of weird objects that we see in the sky and in the rain forest. Everywhere around us, wherever we look, we see evidence of increasing order and increasing information. The technology arising from Shannon’s discoveries is only a local acceleration of the natural growth of information.
  • . Lord Kelvin, one of the leading physicists of that time, promoted the heat death dogma, predicting that the flow of heat from warmer to cooler objects will result in a decrease of temperature differences everywhere, until all temperatures ultimately become equal. Life needs temperature differences, to avoid being stifled by its waste heat. So life will disappear
  • Thanks to the discoveries of astronomers in the twentieth century, we now know that the heat death is a myth. The heat death can never happen, and there is no paradox. The best popular account of the disappearance of the paradox is a chapter, “How Order Was Born of Chaos,” in the book Creation of the Universe, by Fang Lizhi and his wife Li Shuxian.2 Fang Lizhi is doubly famous as a leading Chinese astronomer and a leading political dissident. He is now pursuing his double career at the University of Arizona.
  • The belief in a heat death was based on an idea that I call the cooking rule. The cooking rule says that a piece of steak gets warmer when we put it on a hot grill. More generally, the rule says that any object gets warmer when it gains energy, and gets cooler when it loses energy. Humans have been cooking steaks for thousands of years, and nobody ever saw a steak get colder while cooking on a fire. The cooking rule is true for objects small enough for us to handle. If the cooking rule is always true, then Lord Kelvin’s argument for the heat death is correct.
  • the cooking rule is not true for objects of astronomical size, for which gravitation is the dominant form of energy. The sun is a familiar example. As the sun loses energy by radiation, it becomes hotter and not cooler. Since the sun is made of compressible gas squeezed by its own gravitation, loss of energy causes it to become smaller and denser, and the compression causes it to become hotter. For almost all astronomical objects, gravitation dominates, and they have the same unexpected behavior. Gravitation reverses the usual relation between energy and temperature. In the domain of astronomy, when heat flows from hotter to cooler objects, the hot objects get hotter and the cool objects get cooler. As a result, temperature differences in the astronomical universe tend to increase rather than decrease as time goes on. There is no final state of uniform temperature, and there is no heat death. Gravitation gives us a universe hospitable to life. Information and order can continue to grow for billions of years in the future, as they have evidently grown in the past.
  • The vision of the future as an infinite playground, with an unending sequence of mysteries to be understood by an unending sequence of players exploring an unending supply of information, is a glorious vision for scientists. Scientists find the vision attractive, since it gives them a purpose for their existence and an unending supply of jobs. The vision is less attractive to artists and writers and ordinary people. Ordinary people are more interested in friends and family than in science. Ordinary people may not welcome a future spent swimming in an unending flood of information.
  • A darker view of the information-dominated universe was described in a famous story, “The Library of Babel,” by Jorge Luis Borges in 1941.3 Borges imagined his library, with an infinite array of books and shelves and mirrors, as a metaphor for the universe.
  • Gleick’s book has an epilogue entitled “The Return of Meaning,” expressing the concerns of people who feel alienated from the prevailing scientific culture. The enormous success of information theory came from Shannon’s decision to separate information from meaning. His central dogma, “Meaning is irrelevant,” declared that information could be handled with greater freedom if it was treated as a mathematical abstraction independent of meaning. The consequence of this freedom is the flood of information in which we are drowning. The immense size of modern databases gives us a feeling of meaninglessness. Information in such quantities reminds us of Borges’s library extending infinitely in all directions. It is our task as humans to bring meaning back into this wasteland. As finite creatures who think and feel, we can create islands of meaning in the sea of information. Gleick ends his book with Borges’s image of the human condition:We walk the corridors, searching the shelves and rearranging them, looking for lines of meaning amid leagues of cacophony and incoherence, reading the history of the past and of the future, collecting our thoughts and collecting the thoughts of others, and every so often glimpsing mirrors, in which we may recognize creatures of the information.

Cancer resembles life 1 billion years ago, say astrobiologists - microbiology, genomics... - 0 views

  • astrobiologists, working with oncologists in the US, have suggested that cancer resembles ancient forms of life that flourished between 600 million and 1 billion years ago.
  • Read more about what this discovery means for cancer research.
  • The genes that controlled the behaviour of these early multicellular organisms still reside within our own cells, managed by more recent genes that keep them in check.It's when these newer controlling genes fail that the older mechanisms take over, and the cell reverts to its earlier behaviours and grows out of control.
  • ...11 more annotations...
  • The new theory, published in the journal Physical Biology, has been put forward by two leading figures in the world of cosmology and astrobiology: Paul Davies, director of the Beyond Center for Fundamental Concepts in Science, Arizona State University; and Charles Lineweaver, from the Australian National University.
  • According to Lineweaver, this suggests that cancer is an atavism, or an evolutionary throwback.
  • In the paper, they suggest that a close look at cancer shows similarities with early forms of multicellular life.
  • “Unlike bacteria and viruses, cancer has not developed the capacity to evolve into new forms. In fact, cancer is better understood as the reversion of cells to the way they behaved a little over one billion years ago, when humans were nothing more than loose-knit colonies of only partially differentiated cells. “We think that the tumours that develop in cancer patients today take the same form as these simple cellular structures did more than a billion years ago,” he said.
  • One piece of evidence to support this theory is that cancers appear in virtually all metazoans, with the notable exception of the bizarre naked mole rat."This quasi-ubiquity suggests that the mechanisms of cancer are deep-rooted in evolutionary history, a conjecture that receives support from both paleontology and genetics," they write.
  • the genes that controlled this early multi-cellular form of life are like a computer operating system's 'safe mode', and when there are failures or mutations in the more recent genes that manage the way cells specialise and interact to form the complex life of today, then the earlier level of programming takes over.
  • Their notion is in contrast to a prevailing theory that cancer cells are 'rogue' cells that evolve rapidly within the body, overcoming the normal slew of cellular defences.
  • However, Davies and Lineweaver point out that cancer cells are highly cooperative with each other, if competing with the host's cells. This suggests a pre-existing complexity that is reminiscent of early multicellular life.
  • cancers' manifold survival mechanisms are predictable, and unlikely to emerge spontaneously through evolution within each individual in such a consistent way.
  • The good news is that this means combating cancer is not necessarily as complex as if the cancers were rogue cells evolving new and novel defence mechanisms within the body.Instead, because cancers fall back on the same evolved mechanisms that were used by early life, we can expect them to remain predictable, thus if they're susceptible to treatment, it's unlikely they'll evolve new ways to get around it.
  • If the atavism hypothesis is correct, there are new reasons for optimism," they write.

Daily Kos: UPDATED: The HB Gary Email That Should Concern Us All - 0 views

  • HB Gary people are talking about creating "personas", what we would call sockpuppets. This is not new. PR firms have been using fake "people" to promote products and other things for a while now, both online and even in bars and coffee houses.
  • But for a defense contractor with ties to the federal government, Hunton & Williams, DOD, NSA, and the CIA -  whose enemies are labor unions, progressive organizations,  journalists, and progressive bloggers,  a persona apparently goes far beyond creating a mere sockpuppet. According to an embedded MS Word document found in one of the HB Gary emails, it involves creating an army of sockpuppets, with sophisticated "persona management" software that allows a small team of only a few people to appear to be many, while keeping the personas from accidentally cross-contaminating each other. Then, to top it off, the team can actually automate some functions so one persona can appear to be an entire Brooks Brothers riot online.
  • Persona management entails not just the deconfliction of persona artifacts such as names, email addresses, landing pages, and associated content.  It also requires providing the human actors technology that takes the decision process out of the loop when using a specific persona.  For this purpose we custom developed either virtual machines or thumb drives for each persona.  This allowed the human actor to open a virtual machine or thumb drive with an associated persona and have all the appropriate email accounts, associations, web pages, social media accounts, etc. pre-established and configured with visual cues to remind the actor which persona he/she is using so as not to accidentally cross-contaminate personas during use.

  • all of this is for the purposes of infiltration, data mining, and (here's the one that really worries me) ganging up on bloggers, commenters  and otherwise "real" people to smear enemies and distort the truth.
  • CEO of HB Gary's Federal subsidiary, to several of his colleagues to present to clients: To build this capability we will create a set of personas on twitter,‭ ‬blogs,‭ ‬forums,‭ ‬buzz,‭ ‬and myspace under created names that fit the profile‭ (‬satellitejockey,‭ ‬hack3rman,‭ ‬etc‭)‬.‭  ‬These accounts are maintained and updated automatically through RSS feeds,‭ ‬retweets,‭ ‬and linking together social media commenting between platforms.‭  ‬With a pool of these accounts to choose from,‭ ‬once you have a real name persona you create a Facebook and LinkedIn account using the given name,‭ ‬lock those accounts down and link these accounts to a selected‭ ‬#‭ ‬of previously created social media accounts,‭ ‬automatically pre-aging the real accounts.
  • one of the team spells out how automation can work so one person can be many personas: Using the assigned social media accounts we can automate the posting of content that is relevant to the persona.  In this case there are specific social media strategy website RSS feeds we can subscribe to and then repost content on twitter with the appropriate hashtags.  In fact using hashtags and gaming some location based check-in services we can make it appear as if a persona was actually at a conference and introduce himself/herself to key individuals as part of the exercise, as one example.  There are a variety of social media tricks we can use to add a level of realness to all fictitious personas
  • It goes far beyond the mere ability for a government stooge, corporation or PR firm to hire people to post on sites like this one. They are talking about creating  the illusion of consensus. And consensus is a powerful persuader. What has more effect, one guy saying BP is not at fault? Or 20 people saying it? For the weak minded, the number can make all the difference.
  • UPDATE: From another email, I found a  government solicitation for this "Persona Management Software". This confirms that in fact, the US Gov. is attempting to use this kind of technology. But it appears from the solicitation it is contracted for use in foreign theaters like Afghanistan and Iraq. I can't imagine why this is posted on an open site. And whenthis was discovered by a couple of HB Gary staffers, they weren't too happy about it either:

In Japan, a Culture That Promotes Nuclear Dependency - NYTimes.com - 0 views

The gym is just one of several big public works projects paid for with the hundreds of millions of dollars this community is receiving for acce
  • the aid has enriched rural communities that were rapidly losing jobs and people to the cities. With no substantial reserves of oil or coal, Japan relies on nuclear power for the energy needed to drive its economic machine. But critics contend that the largess has also made communities dependent on central government spending — and thus unwilling to rock the boat by pushing for robust safety measures.
  • Tsuneyoshi Adachi, a 63-year-old fisherman, joined the huge protests in the 1970s and 1980s against the plant’s No. 2 reactor. He said many fishermen were angry then because chlorine from the pumps of the plant’s No. 1 reactor, which began operating in 1974, was killing seaweed and fish in local fishing grounds. However, Mr. Adachi said, once compensation payments from the No. 2 reactor began to flow in, neighbors began to give him cold looks and then ignore him. By the time the No. 3 reactor was proposed in the early 1990s, no one, including Mr. Adachi, was willing to speak out against the plant. He said that there was the same peer pressure even after the accident at Fukushima, which scared many here because they live within a few miles of the Shimane plant. “Sure, we are all worried in our hearts about whether the same disaster could happen at the Shimane nuclear plant,” Mr. Adachi said. However, “the town knows it can no longer survive economically without the nuclear plant.”

  • Much of this flow of cash was the product of the Three Power Source Development Laws, a sophisticated system of government subsidies created in 1974 by Kakuei Tanaka, the powerful prime minister who shaped Japan’s nuclear power landscape and used big public works projects to build postwar Japan’s most formidable political machine. The law required all Japanese power consumers to pay, as part of their utility bills, a tax that was funneled to communities with nuclear plants. Officials at the Ministry of Economy, Trade and Industry, which regulates the nuclear industry, and oversees the subsidies, refused to specify how much communities have come to rely on those subsidies. “This is money to promote the locality’s acceptance of a nuclear plant,” said Tatsumi Nakano of the ministry’s Agency for Natural Resources and Energy.

BrainGate gives paralysed the power of mind control | Science | The Observer - 0 views

  • brain-computer interface, or BCI
  • is a branch of science exploring how computers and the human brain can be meshed together. It sounds like science fiction (and can look like it too), but it is motivated by a desire to help chronically injured people. They include those who have lost limbs, people with Lou Gehrig's disease, or those who have been paralysed by severe spinal-cord injuries. But the group of people it might help the most are those whom medicine assumed were beyond all hope: sufferers of "locked-in syndrome".
  • These are often stroke victims whose perfectly healthy minds end up trapped inside bodies that can no longer move. The most famous example was French magazine editor Jean-Dominique Bauby who managed to dictate a memoir, The Diving Bell and the Butterfly, by blinking one eye. In the book, Bauby, who died in 1997 shortly after the book was published, described the prison his body had become for a mind that still worked normally.

  • Now the project is involved with a second set of human trials, pushing the technology to see how far it goes and trying to miniaturise it and make it wireless for a better fit in the brain. BrainGate's concept is simple. It posits that the problem for most patients does not lie in the parts of the brain that control movement, but with the fact that the pathways connecting the brain to the rest of the body, such as the spinal cord, have been broken. BrainGate plugs into the brain, picks up the right neural signals and beams them into a computer where they are translated into moving a cursor or controlling a computer keyboard. By this means, paralysed people can move a robot arm or drive their own wheelchair, just by thinking about it.
  • he and his team are decoding the language of the human brain. This language is made up of electronic signals fired by billions of neurons and it controls everything from our ability to move, to think, to remember and even our consciousness itself. Donoghue's genius was to develop a deceptively small device that can tap directly into the brain and pick up those signals for a computer to translate them. Gold wires are implanted into the brain's tissue at the motor cortex, which controls movement. Those wires feed back to a tiny array – an information storage device – attached to a "pedestal" in the skull. Another wire feeds from the array into a computer. A test subject with BrainGate looks like they have a large plug coming out the top of their heads. Or, as Donoghue's son once described it, they resemble the "human batteries" in The Matrix.
  • BrainGate's highly advanced computer programs are able to decode the neuron signals picked up by the wires and translate them into the subject's desired movement. In crude terms, it is a form of mind-reading based on the idea that thinking about moving a cursor to the right will generate detectably different brain signals than thinking about moving it to the left.
  • The technology has developed rapidly, and last month BrainGate passed a vital milestone when one paralysed patient went past 1,000 days with the implant still in her brain and allowing her to move a computer cursor with her thoughts. The achievement, reported in the prestigious Journal of Neural Engineering, showed that the technology can continue to work inside the human body for unprecedented amounts of time.
  • Donoghue talks enthusiastically of one day hooking up BrainGate to a system of electronic stimulators plugged into the muscles of the arm or legs. That would open up the prospect of patients moving not just a cursor or their wheelchair, but their own bodies.
  • If Nagle's motor cortex was no longer working healthily, the entire BrainGate project could have been rendered pointless. But when Nagle was plugged in and asked to imagine moving his limbs, the signals beamed out with a healthy crackle. "We asked him to imagine moving his arm to the left and to the right and we could hear the activity," Donoghue says. When Nagle first moved a cursor on a screen using only his thoughts, he exclaimed: "Holy shit!"
  • BrainGate and other BCI projects have also piqued the interest of the government and the military. BCI is melding man and machine like no other sector of medicine or science and there are concerns about some of the implications. First, beyond detecting and translating simple movement commands, BrainGate may one day pave the way for mind-reading. A device to probe the innermost thoughts of captured prisoners or dissidents would prove very attractive to some future military or intelligence service. Second, there is the idea that BrainGate or other BCI technologies could pave the way for robot warriors controlled by distant humans using only their minds. At a conference in 2002, a senior American defence official, Anthony Tether, enthused over BCI. "Imagine a warrior with the intellect of a human and the immortality of a machine." Anyone who has seen Terminator might worry about that.
  • Donoghue acknowledges the concerns but has little time for them. When it comes to mind-reading, current BrainGate technology has enough trouble with translating commands for making a fist, let alone probing anyone's mental secrets
  • As for robot warriors, Donoghue was slightly more circumspect. At the moment most BCI research, including BrainGate projects, that touch on the military is focused on working with prosthetic limbs for veterans who have lost arms and legs. But Donoghue thinks it is healthy for scientists to be aware of future issues. "As long as there is a rational dialogue and scientists think about where this is going and what is the reasonable use of the technology, then we are on a good path," he says.

    The robotic arm clutched a glass and swung it over a series of coloured dots that resembled a Twister gameboard. Behind it, a woman sat entirely immobile in a wheelchair. Slowly, the arm put the glass down, narrowly missing one of the dots. "She's doing that!" exclaims Professor John Donoghue, watching a video of the scene on his office computer - though the woman onscreen had not moved at all. "She actually has the arm under her control," he says, beaming with pride. "We told her to put the glass down on that dot." The woman, who is almost completely paralysed, was using Donoghue's groundbreaking technology to control the robot arm using only her thoughts. Called BrainGate, the device is implanted into her brain and hooked up to a computer to which she sends mental commands. The video played on, giving Donoghue, a silver-haired and neatly bearded man of 62, even more reason to feel pleased. The patient was not satisfied with her near miss and the robot arm lifted the glass again. After a brief hover, the arm positioned the glass on the dot.

  • Humanity’s End. The main premise of the book is that proposals that would supposedly promise to make us smarter like never before or add thousands of years to our live seem rather far fetched and the domain of mere fantasy. However, it is these very proposals which form the basis of many of the ideas and thoughts presented by advocates of radical enhancement and which are beginning to move from the sidelines to the centre of main stream discussion. A variety of technologies and therapies are being presented to us as options to expand our capabilities and capacities in order for us to become something other than human.
  • Agar takes issue with this and argues against radical human enhancement. He structures his analysis and discussion by focusing on four key figures and their proposals which help to form the core of the case for radical enhancement debate.  First to be examined by Agar is Ray Kurzweil who argues that Man and Machine will become one as technology allows us to transcend our biology. Second, is Aubrey de Grey who is a passionate advocate and pioneer of anti-ageing therapies which allow us to achieve “longevity escape velocity”. Next is Nick Bostrom, a leading transhumanist who defends the morality and rationality of enhancement and finally James Hughes who is a keen advocate of a harmonious democracy of the enhanced and un-enhanced.
  • He avoids falling into any of the pitfalls of basing his argument solely upon the “playing God” question but instead seeks to posit a well founded argument in favour of the precautionary principle.
  • ...10 more annotations...
  • Agar directly tackles Hughes’ ideas of a “democratic transhumanism.” Here as post-humans and humans live shoulder to shoulder in wonderful harmony, all persons have access to the technologies they want in order to promote their own flourishing.  Under girding all of this is the belief that no human should feel pressurised to become enhance. Agar finds no comfort with this and instead can foresee a situation where it would be very difficult for humans to ‘choose’ to remain human.  The pressure to radically enhance would be considerable given the fact that the radically enhanced would no doubt be occupying the positions of power in society and would consider the moral obligation to utilise to the full enhancement techniques as being a moral imperative for the good of society.  For those who were able to withstand then a new underclass would no doubt emerge between the enhanced and the un-enhanced. This is precisely the kind of society which Hughes appears to be overly optimistic will not emerge but which is more akin to Lee Silver’s prediction of the future with the distinction made between the "GenRich" and the "naturals”.  This being the case, the author proposes that we have two options: radical enhancement is either enforced across the board or banned outright. It is the latter option which Agar favours but crucially does not elaborate further on so it is unclear as to how he would attempt such a ban given the complexity of the issue. This is disappointing as any general initial reflections which the author felt able to offer would have added to the discussion and added further strength to his line of argument.
  • A Transhuman Manifesto The final focus for Agar is James Hughes, who published his transhumanist manifesto Citizen Cyborg in 2004. Given the direct connection with politics and public policy this for me was a particularly interesting read. The basic premise to Hughes argument is that once humans and post humans recognise each other as citizens then this will mark the point at which they will be able to get along with each other.
  • Agar takes to task the argument Bostrom made with Toby Ord, concerning claims against enhancement. Bostrom and Ord argue that it boils down to a preference for the status quo; current human intellects and life spans are preferred and deemed best because they are what we have now and what we are familiar with (p. 134).  Agar discusses the fact that in his view, Bostrom falls into a focalism – focusing on and magnifying the positives whilst ignoring the negative implications.  Moreover, Agar goes onto develop and reiterate his earlier point that the sort of radical enhancements Bostrom et al enthusiastically support and promote take us beyond what is human so they are no longer human. It therefore cannot be said to be human enhancement given the fact that the traits or capacities that such enhancement afford us would be in many respects superior to ours, but they would not be ours.
  • With his law of accelerating returns and talk of the Singularity Ray Kurzweil proposes that we are speeding towards a time when our outdated systems of neurons and synapses will be traded for far more efficient electronic circuits, allowing us to become artificially super-intelligent and transferring our minds from brains into machines.
  • Having laid out the main ideas and thinking behind Kurzweil’s proposals, Agar makes the perceptive comment that despite the apparent appeal of greater processing power it would nevertheless be no longer human. Introducing chips to the human body and linking into the human nervous system to computers as per Ray Kurzweil’s proposals will prove interesting but it goes beyond merely creating a copy of us in order to that future replication and uploading can take place. Rather it will constitute something more akin to an upgrade. Electrochemical signals that the brain use to achieve thought travel at 100 metres per second. This is impressive but contrast this with the electrical signals in a computer which travel at 300 million metres per second then the distinction is clear. If the predictions are true how will such radically enhanced and empowered beings live not only the unenhanced but also what will there quality of life really be? In response, Agar favours something what he calls “rational biological conservatism” (pg. 57) where we set limits on how intelligent we can become in light of the fact that it will never be rational to us for human beings to completely upload their minds onto computers.
  • Agar then proceeds to argue that in the pursuit of Kurzweil enhanced capacities and capabilities we might accidentally undermine capacities of equal value. This line of argument would find much sympathy from those who consider human organisms in “ecological” terms, representing a profound interconnectedness which when interfered with presents a series of unknown and unexpected consequences. In other words, our specifies-specific form of intelligence may well be linked to species-specific form of desire. Thus, if we start building upon and enhancing our capacity to protect and promote deeply held convictions and beliefs then due to the interconnectedness, it may well affect and remove our desire to perform such activities (page 70). Agar’s subsequent discussion and reference to the work of Jerry Foder, philosopher and cognitive scientist is particularly helpful in terms of the functioning of the mind by modules and the implications of human-friendly AI verses human-unfriendly AI.
  • In terms of the author’s discussion of Aubrey de Grey, what is refreshing to read from the outset is the author’s clear grasp of Aubrey’s ideas and motivation. Some make the mistake of thinking he is the man who wants to live forever, when in actual fact this is not the case.  De Grey wants to reverse the ageing process - Strategies for Engineered Negligible Senescence (SENS) so that people are living longer and healthier lives. Establishing this clear distinction affords the author the opportunity to offer more grounded critiques of de Grey’s than some of his other critics. The author makes plain that de Grey’s immediate goal is to achieve longevity escape velocity (LEV), where anti-ageing therapies add years to life expectancy faster than age consumes them.
  • In weighing up the benefits of living significantly longer lives, Agar posits a compelling argument that I had not fully seen before. In terms of risk, those radically enhanced to live longer may actually be the most risk adverse and fearful people to live. Taking the example of driving a car, a forty year-old senescing human being who gets into their car to drive to work and is involved in a fatal accident “stands to lose, at most, a few healthy, youthful years and a slightly larger number of years with reduced quality” (p.116). In stark contrast should a negligibly senescent being who drives a car and is involved in an accident resulting in their death, stands to lose on average one thousand, healthy, youthful years (p.116).  
  • De Grey’s response to this seems a little flippant; with the end of ageing comes an increased sense of risk-aversion so the desire for risky activity such as driving will no longer be prevalent. Moreover, plus because we are living for longer we will not be in such a hurry to get to places!  Virtual reality comes into its own at this point as a means by which the negligibly senescent being ‘adrenaline junkie’ can be engaged with activities but without the associated risks. But surely the risk is part of the reason why they would want to engage in snow boarding, bungee jumping et al in the first place. De Grey’s strategy seemingly fails to appreciate the extent to which human beings want “direct” contact with the “real” world.
  • Continuing this idea further though, Agar’s subsequent discussion of the role of fire-fighters is an interesting one.  A negligibly senescent fire fighter may stand to loose more when they are trapped in a burning inferno but being negligibly senescent means that they are better fire-fighters by virtue of increase vitality. Having recently heard de Grey speak and had the privilege of discussing his ideas further with him, Agar’s discussion of De Grey were a particular highlight of the book and made for an engaging discussion. Whilst expressing concern and doubt in relation to De Grey’s ideas, Agar is nevertheless quick and gracious enough to acknowledge that if such therapies could be achieved then De Grey is probably the best person to comment on and achieve such therapies given the depth of knowledge and understanding that he has built up in this area.

  • There is something almost religious about Kurzweil’s scientism, an observation he himself makes in the film, noting the similarities between his goals and that of the world’s religions: “the idea of a profound transformation in the future, eternal life, bringing back the dead—but the fact that we’re applying technology to achieve the goals that have been talked about in all human philosophies is not accidental because it does reflect the goal of humanity.” Although the film never discloses Kurzweil’s religious beliefs (he was raised by Jewish parents as a Unitarian Universalist), in a (presumably) unintentionally humorous moment that ends the film Kurzweil reflects on the God question and answers it himself: “Does God exist? I would say, ‘Not yet.’”
  • Transcendent Man is Barry Ptolemy’s beautifully crafted and artfully edited documentary film about Kurzweil and his quest to save humanity.
  • Transcendent Man pulls viewers in through Kurzweil’s visage of a future in which we merge with our machines and vastly extend our longevity and intelligence to the point where even death will be defeated. This point is what Kurzweil calls the “singularity” (inspired by the physics term denoting the infinitely dense point at the center of a black hole), and he arrives at the 2029 date by extrapolating curves based on what he calls the “law of accelerating returns.” This is “Moore’s Law” (the doubling of computing power every year) on steroids, applied to every conceivable area of science, technology and economics.
  • ...6 more annotations...
  • Ptolemy’s portrayal of Kurzweil is unmistakably positive, but to his credit he includes several critics from both religion and science. From the former, a radio host named Chuck Missler, a born-again Christian who heads the Koinonia Institute (“dedicated to training and equipping the serious Christian to sojourn in today’s world”), proclaims: “We have a scenario laid out that the world is heading for an Armageddon and you and I are going to be the generation that’s alive that is going to see all this unfold.” He seems to be saying that Kurzweil is right about the second coming, but wrong about what it is that is coming. (Of course, Missler’s prognostication is the N+1 failed prophecy that began with Jesus himself, who told his followers (Mark 9:1): “Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.”) Another religiously-based admonition comes from the Stanford University neuroscientist William Huribut, who self-identifies as a “practicing Christian” who believes in immortality, but not in the way Kurzweil envisions it. “Death is conquered spiritually,” he pronounced.
  • On the science side of the ledger, Neil Gershenfeld, director of the Center for Bits and Atoms at the Massachusetts Institute of Technology, sagely notes: “What Ray does consistently is to take a whole bunch of steps that everybody agrees on and take principles for extrapolating that everybody agrees on and show they lead to things that nobody agrees on.” Likewise, the estimable futurist Kevin Kelly, whose 2010 book What Technology Wants paints a much more realistic portrait of what our futures may (or may not) hold
  • Kelly agrees that Kurzweil’s exponential growth curves are accurate but that the conclusions and especially the inspiration drawn from them are not. “He seems to have no doubts about it and in this sense I think he is a prophetic type figure who is completely sure and nothing can waiver his absolute certainty about this. So I would say he is a modern day prophet…that’s wrong.”
  • Transcendent Man is clearly meant to be an uplifting film celebrating all the ways science and technology have and are going to enrich our lives.
  • An especially lachrymose moment is when Kurzweil is rifling through his father’s journals and documents in a storage room dedicated to preserving his memory until the day that all this “data” (including Ray’s own fading memories) can be reconfigured into an A.I. simulacrum so that father and son can be reunited.
  • Although Kurzweil says he is optimistic and cheery about life, he can’t seem to stop talking about death: “It’s such a profoundly sad, lonely feeling that I really can’t bear it,” he admits. “So I go back to thinking about how I’m not going to die.” One wonders how much of life he is missing by over thinking death, or how burdensome it must surely be to imbibe over 200 supplement tables a day and have your blood tested and cleansed every couple of months, all in an effort to reprogram the body’s biochemistry.

The Good Short Life With A.L.S. - NYTimes.com - 0 views

  • Lingering would be a colossal waste of love and money.
  • I’d rather die. I respect the wishes of people who want to live as long as they can. But I would like the same respect for those of us who decide — rationally — not to. I’ve done my homework. I have a plan. If I get pneumonia, I’ll let it snuff me out. If not, there are those other ways. I just have to act while my hands still work: the gun, narcotics, sharp blades, a plastic bag, a fast car, over-the-counter drugs, oleander tea (the polite Southern way), carbon monoxide, even helium. That would give me a really funny voice at the end. I have found the way. Not a gun. A way that’s quiet and calm. Knowing that comforts me. I don’t worry about fatty foods anymore. I don’t worry about having enough money to grow old. I’m not going to grow old. I’m having a wonderful time.
  •  
    We obsess in this country about how to eat and dress and drink, about finding a job and a mate. About having sex and children. About how to live. But we don't talk about how to die. We act as if facing death weren't one of life's greatest, most absorbing thrills and challenges. Believe me, it is. This is not dull. But we have to be able to see doctors and machines, medical and insurance systems, family and friends and religions as informative - not governing - in order to be free.

  • Google could still put ads in front of more people than Facebook, but Facebook knows so much more about those people. Advertisers and publishers cherish this kind of personal information, so much so that they are willing to put the Facebook brand before their own. Exhibit A: www.facebook.com/nike, a company with the power and clout of Nike putting their own brand after Facebook’s?
  • As it turned out, sharing was not broken. Sharing was working fine and dandy, Google just wasn’t part of it. People were sharing all around us and seemed quite happy. A user exodus from Facebook never materialized. I couldn’t even get my own teenage daughter to look at Google+ twice, “social isn’t a product,” she told me after I gave her a demo, “social is people and the people are on Facebook.” Google was the rich kid who, after having discovered he wasn’t invited to the party, built his own party in retaliation. The fact that no one came to Google’s party became the elephant in the room.

Stumbling and Mumbling: The pretence of knowledge - 0 views

  • One of the more unpleasant aspects of the New Labour government was its anti-Hayekian pretence that central government could acquire knowledge which, in fact, is unobtainable.
  • it is impossible to predict what research will be commercially useful. History is full of examples of businessmen and scientists - let alone politicians - utterly failing to anticipate commercial uses, for example:“There is not the slightest indication that nuclear energy will ever be obtainable”"The wireless music box has no imaginable commercial value.” "Radio has no future. Heavier-than-air flying machines are impossible. X-rays will prove to be a hoax.""While theoretically and technically television may be feasible, commercially and financially it is an impossibility." “There is no reason anyone would want a computer in their home."“This 'telephone' has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us."
  • The notion that government can cut only “useless” science funding is an egregious pretence to know things that cannot be known. Instead, such cuts operate much as financial constraints for business operate: they diminish the ecology upon which natural selection operates.

  • Statistical Literacy Why take this course? We are misled by numbers and by our misunderstanding of probability.
  • Our world is shaped by widespread statistical illiteracy. We fear things that probably won’t kill us (terrorist attacks) and ignore things that probably will (texting while driving). We buy lottery tickets. We fall prey to misleading gut instincts, which lead to biases like loss aversion—an inability to gauge risk against potential gain. The effects play out in the grocery store, the office, and the voting booth (not to mention the bedroom: People who are more risk-averse are less successful in love).
  • We are now 53 percent more likely than our parents to trust polls of dubious merit. (That figure is totally made up. See?) Where do all these numbers that we remember so easily and cite so readily come from? How are they calculated, and by whom? How do we misuse them to make them say what we want them to? We’ll explore all of these questions in a sequence on sourcing statistics.
  • ...9 more annotations...
  • probabilistic intuition. We’ll learn to judge what’s likely and unlikely—and what’s impossible to know. We’ll learn about distorting habits of mind like selection bias—and how to guard against them. We’ll gamble. We’ll read The Art of Probability for Scientists and Engineers by Richard Hamming, Expert Political Judgment by Philip Tetlock, and How to Cheat Your Friends at Poker by Penn Jillette and Mickey Lynn.
  • Post-State Diplomacy Why take this course? As the world becomes evermore atomized, understanding the new leaders and constituencies becomes increasingly important.
  • tribal insurgents to multinational corporations, private charities to pirate gangs, religious movements to armies for hire, a range of organizations now compete with (and sometimes eclipse) the nation-states in which they reside. Without capitals or traditional constituencies, they can’t be persuaded or deterred by traditional tactics.
  • that doesn’t mean diplomacy is dead; quite the opposite. Negotiating with these parties requires the same skills as dealing with belligerent nations—understanding the shareholders and alliances they must answer to, the cultures that inform how they behave, and the religious, economic, and political interests they must address.
  • Power has always depended on who can provide justice, commerce, and stability.
  • Remix Culture Why take this course? Modern artists don’t start with a blank page or empty canvas. They start with preexisting works. What you’ll learn: How to analyze—and create—artworks made out of other artworks
  • philosophical roots of remix culture and study seminal works like Robert Rauschenberg’s Monogram and Jorge Luis Borges’ Pierre Menard, Author of Don Quixote. And we’ll examine modern-day exemplars from DJ Shadow’s Endtroducing to Auto-Tune the News.
  • Applied Cognition Why take this course? You have to know the brain to train the brain. What you’ll learn: How the mind works and how you can make it work for you.
  • Writing for New Forms Why take this course? You can write a cogent essay, but can you write it in 140 characters or less? What you’ll learn: How to adapt your message to multiple formats and audiences—human and machine.

Short Sharp Science: Computer beats human at Japanese chess for first time - 0 views

  • A computer has beaten a human at shogi, otherwise known as Japanese chess, for the first time.
  • computers have been beating humans at western chess for years, and when IBM's Deep Blue beat Gary Kasparov in 1997, it was greeted in some quarters as if computers were about to overthrow humanity. That hasn't happened yet, but after all, western chess is a relatively simple game, with only about 10123 possible games existing that can be played out. Shogi is a bit more complex, though, offering about 10224 possible games.
  • Japan's national broadcaster, NHK, reported that Akara "aggressively pursued Shimizu from the beginning". It's the first time a computer has beaten a professional human player.

  • The Japan Shogi Association, incidentally, seems to have a deep fear of computers beating humans. In 2005, it introduced a ban on professional members playing computers without permission, and Shimizu's defeat was the first since a simpler computer system was beaten by a (male) champion, Akira Watanabe, in 2007.
  • Perhaps the association doesn't mind so much if a woman is beaten: NHK reports that the JSA will conduct an in-depth analysis of the match before it decides whether to allow the software to challenge a higher-ranking male professional player.
