As We May Think
A future fabulation from Vannevar Bush’s 1945 ‘As We May Think’:
Consider a future device for individual use, which is a sort of mechanized private file and library. It needs a name, and, to coin one at random, “memex” will do. A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility. It is an enlarged intimate supplement to his memory.
It consists of a desk, and while it can presumably be operated from a distance, it is primarily the piece of furniture at which he works. On the top are slanting translucent screens, on which material can be projected for convenient reading. There is a keyboard, and sets of buttons and levers. Otherwise it looks like an ordinary desk.
In one end is the stored material. The matter of bulk is well taken care of by improved microfilm. Only a small part of the interior of the memex is devoted to storage, the rest to mechanism. Yet if the user inserted 5000 pages of material a day it would take him hundreds of years to fill the repository, so he can be profligate and enter material freely.
Most of the memex contents are purchased on microfilm ready for insertion. Books of all sorts, pictures, current periodicals, newspapers, are thus obtained and dropped into place. Business correspondence takes the same path. And there is provision for direct entry. On the top of the memex is a transparent platen. On this are placed longhand notes, photographs, memoranda, all sorts of things. When one is in place, the depression of a lever causes it to be photographed onto the next blank space in a section of the memex film, dry photography being employed.
There is, of course, provision for consultation of the record by the usual scheme of indexing. If the user wishes to consult a certain book, he taps its code on the keyboard, and the title page of the book promptly appears before him, projected onto one of his viewing positions. Frequently-used codes are mnemonic, so that he seldom consults his code book; but when he does, a single tap of a key projects it for his use. Moreover, he has supplemental levers. On deflecting one of these levers to the right he runs through the book before him, each page in turn being projected at a speed which just allows a recognizing glance at each. If he deflects it further to the right, he steps through the book 10 pages at a time; still further at 100 pages at a time. Deflection to the left gives him the same control backwards.
A special button transfers him immediately to the first page of the index. Any given book of his library can thus be called up and consulted with far greater facility than if it were taken from a shelf. As he has several projection positions, he can leave one item in position while he calls up another. He can add marginal notes and comments, taking advantage of one possible type of dry photography, and it could even be arranged so that he can do this by a stylus scheme, such as is now employed in the telautograph seen in railroad waiting rooms, just as though he had the physical page before him.
…
Wholly new forms of encyclopedias will appear, ready made with a mesh of associative trails running through them, ready to be dropped into the memex and there amplified. The lawyer has at his touch the associated opinions and decisions of his whole experience, and of the experience of friends and authorities. The patent attorney has on call the millions of issued patents, with familiar trails to every point of his client’s interest. The physician, puzzled by a patient’s reactions, strikes the trail established in studying an earlier similar case, and runs rapidly through analogous case histories, with side references to the classics for the pertinent anatomy and histology. The chemist, struggling with the synthesis of an organic compound, has all the chemical literature before him in his laboratory, with trails following the analogies of compounds, and side trails to their physical and chemical behavior.
The historian, with a vast chronological account of a people, parallels it with a skip trail which stops only on the salient items, and can follow at any time contemporary trails which lead him all over civilization at a particular epoch. There is a new profession of trail blazers, those who find delight in the task of establishing useful trails through the enormous mass of the common record. The inheritance from the master becomes, not only his additions to the world’s record, but for his disciples the entire scaffolding by which they were erected.
Thus science may implement the ways in which man produces, stores, and consults the record of the race. It might be striking to outline the instrumentalities of the future more spectacularly, rather than to stick closely to methods and elements now known and undergoing rapid development, as has been done here. Technical difficulties of all sorts have been ignored, certainly, but also ignored are means as yet unknown which may come any day to accelerate technical progress as violently as did the advent of the thermionic tube. In order that the picture may not be too commonplace, by reason of sticking to present-day patterns, it may be well to mention one such possibility, not to prophesy but merely to suggest, for prophecy based on extension of the known has substance, while prophecy founded on the unknown is only a doubly involved guess.
Google’s Android Allows Soldiers to Put Drones on Buddy List
By Jeremy Hsu
Google’s Android operating system for cell phones could allow soldiers to track fellow squad members and even unmanned drones in real time on a map — as long as the humans and robots are on their buddy list.
That’s just one use of an Android-based application developed by defense giant Raytheon. The Raytheon Android Tactical System (RATS) costs just a few hundred dollars per user, as opposed to thousands for other systems, and allows anyone familiar with a smart phone to immediately start using it.
For instance, warfighters can watch their little drone buddy’s flight patterns on a map, or even get streaming video from the overhead aerial view. RATS also enables soldiers to send snapshots of suspects to the Department of Defense’s private data network for immediate identification, and could even include biometric scanners to capture fingerprints in the near future.
Raytheon plans to deploy RATS within the next month or so, after two years of development, according to Forbes. We’re looking forward to the future editions where users can control their robot swarms using basic body language.
Plug and Play: Researchers Expand Clinical Study of Neural Interface Brain Implant
Scientific American | 12 June, 2009
Having proved in 2004 that plugging a sensor into the human brain’s motor cortex could turn the thoughts of paralysis victims into action, a team of Brown University scientists now has the green light from the U.S. Food and Drug Administration (FDA) and the Massachusetts General Hospital (MGH) institutional review board to expand its efforts developing technology that reconnects the brain to lifeless limbs.
Brown’s BrainGate Neural Interface System—conceived in 2000 with the help of a $4.25-million U.S. Defense Department grant—includes a baby aspirin–size brain sensor containing 100 electrodes, each thinner than a human hair, that connects to the surface of the motor cortex (the part of the brain that enables voluntary movement), registers electrical signals from nearby neurons, and transmits them through gold wires to a set of computers, processors and monitors. (ScientificAmerican.com in 2006 wrote about one patient’s experience using BrainGate during its first phase of trials.)
The researchers designed BrainGate to assist those suffering from spinal cord injuries, muscular dystrophy, brain stem stroke, amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s Disease), and other motor neuron diseases. During the initial testing five years ago, patients suffering from paralysis demonstrated their ability to use brain signals sent from their motor cortex to control external devices such as computer screen cursors and robotic arms just by thinking about them. “The signals may have been disconnected from the (participant’s) limb, but they were still there,” says Leigh Hochberg, a Brown associate professor of engineering and a vascular and critical care neurologist at MGH who is helping lead the research.
Due to the high risk of plugging a device directly into the brain, the FDA in 2004 granted the BrainGate system an investigational device exemption so that researchers could begin testing the unit in patients and collect data about its safety and effectiveness. Thanks to the success of those early tests, the researchers last week kicked off a pilot clinical trial, dubbed BrainGate2. Although the technology is similar to what was used in the original testing, the researchers are looking to enlist up to 15 patients this time and gather more information that will help them better understand brain signals as well as “the method by which we decode them,” Hochberg says. Since the initial four-person clinical trial launched five years ago, “we have a better appreciation for things that we need to learn.”
A successful BrainGate2 trial could open up a number of new possibilities, including the use of a second sensor to stimulate both sides of the motor cortex, says John Donoghue, a Brown neuroscience professor and director of the Brown Institute for Brain Science. Researchers thus far have implanted the sensor in the side of the brain that controls a patient’s dominant side—the left cortex for righties and the right cortex for lefties.
BrainGate2 is part of a larger mission to help paralysis victims regain control of their bodies. “We want to reconnect the brain back to the muscles and eventually back to the entire limb,” Donoghue says. “We are attempting to recreate parts of the nervous system that have been disconnected from the brain.”
Hochberg expects this second phase to last for several years, “depending on what we learn and how quickly we learn it.” The research project has received about $8 million in funding over the past three years from a number of organizations, including the National Institutes of Health (NIH) and the U.S. Department of Veterans Affairs.

A promising start (see above), a possible ends? (see below)
A clip from series episode ‘Brain Scratch’ from the series ‘Cowboy Bebop’ directed by Shinichiro Watanabe.
In this possible future, ‘Scratch’ is a cult that believes in achieving eternal life by digitising the soul and uploading it onto the internet. As cult members start committing suicide a bounty is put out for their leader Dr. Landes. But there is no such man. He is a fictional figure created by 15 year old paralysis victim Ronnie Spangoen. While his body is vegetated, his brain is connected to the internet where he is free to live without the burdens of physicality.
Spike Spiegel: Why do you kill off members of your own group,Whats the point of that?
Dr. Londes: I am not forcing anything on anyone. They are merely practicing a faith they decided to believe in of their own free will. Tell me, Why do you think people believe in god ? Because they want to. It’s not easy living in an ugly corrupt world. There is no certainty, nothing to hope for. People are lost, so they reach out. Don’t you get it ? God didn’t create humans… No!, Its humans who created god
In Scratch, men can become gods. Living digitally means living without pain. Without pain and thus without fear. Without fear and thus with no restraint- freedom; absolute freedom. Is this a good thing? Well…. living without consequences means we lack empathy. No empathy, no morality. This situation inevitably breeds a new kind of criminal. Where there are no direct consequences we are more likely to operate without restraint. Moral boundaries are not only blurred, they cease to exist.
And of justice.
In the example of Ronnie Spangoen, a warrant was put out for his physical arrest. But it’s useless to arrest his physical body and so his brain is disconnected. Now with no way to engage meaningfully with the outside world, he is a prisoner in his own body. But is this ethical? Is this ‘justice’? In the new world ‘justice’ will be the next issue of contention.
Spy Fears: Twitter Terrorists, Cell Phone Jihadists
Could Twitter become terrorists’ newest killer app? A draft Army intelligence report, making its way through spy circles, thinks the miniature messaging software could be used as an effective tool for coordinating militant attacks.
For years, American analysts have been concerned that militants would take advantage of commercial hardware and software to help plan and carry out their strikes. Everything from online games to remote-controlled toys to social network sites to garage door openers has been fingered as possible tools for mayhem.
This recent presentation — put together on the Army’s 304th Military Intelligence Battalion and found on the Federation of the American Scientists website — focuses on some of the newer applications for mobile phones: digital maps, GPS locators, photo swappers, and Twitter mash-ups of it all.
The report is roughly divided into two halves. The first is based mostly on chatter from Al-Qaeda-affiliated online forums. One Islamic extremist site discusses, for example, the benefits of “using a mobile phone camera to monitor the enemy and its mechanisms.” Another focuses on the benefits of the Nokia 6210 Navigator, and how its GPS utilities could be used for “marksmanship, border crossings, and in concealment of supplies.” Such software could allow jihadists to pick their way across multiple routes, identifying terrain features as they go. A third extremist forum recommends the installation of voice-modification software to conceal one’s identity when making calls. Excerpts from a fourth site show cell phone wallpapers that wannabe jihadists can use to express their affinity for radicalism:
Then the presentation launches into an even-more theoretical discussion of how militants might pair some of these mobile applications with Twitter, to magnify their impact. After all, “Twitter was recently used as a countersurveillance, command and control, and movement tool by activists at the Republican National Convention,” the report notes.”The activists would Tweet each other and their Twitter pages to add information on what was happening with Law Enforcement near real time.”
Terrorists haven’t done anything similar, the Army report concedes – although it does note that there are “multiple pro and anti Hezbollah Tweets.” Instead, the presentation lays out three possible scenarios in which Twitter could become a militant’s friend:
Scenario 1: Terrorist operative “A” uses Twitter with… a cell phone camera/video function to send back messages, and to receive messages, from the rest of his [group]… Other members of his [group] receive near real time updates (similar to the movement updates that were sent by activists at the RNC) on how, where, and the number of troops that are moving in order to conduct an ambush.
Scenario 2: Terrorist operative “A” has a mobile phone for Tweet messaging and for taking images. Operative “A” also has a separate mobile phone that is actually an explosive device and/or a suicide vest for remote detonation. Terrorist operative “B” has the detonator and a mobile to view “A’s” Tweets and images. This may allow ”B” to select the precise moment of remote detonation based on near real time movement and imagery that is being sent by “A.”
Scenario 3: Cyber Terrorist operative “A” finds U.S. [soldier] Smith’s Twitter account. Operative “A” joins Smith’s Tweets and begins to elicit information from Smith. This information is then used for… identity theft, hacking, and/or physical [attacks]. This scenario… has already been discussed for other social networking sites, such as My Space and/or Face Book.
Steven Aftergood, a veteran intelligence analyst at the Federation of the American Scientists, doesn’t dismiss the Army presentation out of hand. But nor does he think it’s tackling a terribly seriously threat. “Red-teaming exercises to anticipate adversary operations are fundamental. But they need to be informed by a sense of what’s realistic and important and what’s not,” he tells Danger Room. “If we have time to worry about ‘Twitter threats’ then we’re in good shape. I mean, it’s important to keep some sense of proportion.”
