The emergent new order

As one of the pioneers of Web publishing, Steven Johnson, co-founder of Feed, went a long way toward proving that the Internet could be a home for intelligent, thought-provoking commentary. Feed, alas, is no more, a victim of the current media recession, but Johnson is very much with us, currently in action juggling the weighty responsibilities of both a new son and a new book: “Emergence: The Connected Lives of Ants, Brains, Cities, and Software.”

Johnson’s first book, 1997′s “Interface Culture,” proposed the ambitious argument that the human-computer interface might be “the art form of the 21st century.” “Emergence” aims at even headier game: Johnson combines elements of complexity and chaos theory to look at how decentralized, adaptive, self-organizing systems flourish in the world today.

If that sounds like a mouthful, that’s because it is — but Johnson’s elegant, crystal-clear narrative style excises jargon in favor of lucid examples drawn from such seemingly disparate worlds as anthills and urban metropolises. And if it also sounds like ground that has been covered before, notably in Kevin Kelly’s 1995 epic “Out of Control,” that’s true too. But Johnson takes Kelly one huge step further by showing how key concepts of complexity theory intersect with the world made possible by the Internet.

Johnson has been making the book-tour rounds over the past few months, a task made doubly challenging by his new baby and the question of relevance in the post Sept. 11 era. For many longtime observers of Internet and computer culture, it’s been difficult to focus on old obsessions while beset on all sides by the realities of war, terrorism and recession. But the likely staying power of “Emergence” is suggested by this: It’s all too easy to fit al-Qaida’s worldwide network of holy warriors into Johnson’s paradigm. The subtitle of “Emergence” could easily be “The Connected Lives of Ants, Brains, Cities, Software, and Jihad.”

Johnson managed to take some time off from tending the needs of his new family to speak with Salon about “Emergence.”

What is the connection between ants, cities, brains and software?



The connection is really that they are all self-organizing decentralized systems that involve a whole host of distributed elements that somehow collectively manage to solve higher-level problems.

The best example is the ant colony that the prologue of the book starts with, where you have this system of 10,000 ants, none of which are actually in charge but somehow they manage to do these very complex engineering tasks and social organization and resource management things that are mesmerizing feats. They look like they should be planned from above, but in fact they are entirely organized by local rules and local interactions. The catchphrase is that the whole is sometimes smarter than the sum of its parts. And when you look at something like an ant colony, the question that you ask is who makes this happen? Who makes this collective intelligence happen? And the answer is everybody and nobody at the same time.

You can take that and look at something like the formation of city neighborhoods. In a traditional organic evolving city, who decided that my neighborhood in downtown Manhattan in the West Village has been for about 120 years a kind of artists’, eclectic, writerly place to live? Well, everybody and nobody; it’s this kind of collective decision that happens. It’s a cluster that forms out of lots of local decisions and has a kind of persistence over time.

Do you think that people have a tough time accepting that nobody is making these decisions? One of the lessons that you might draw from “Emergence” is that you just can’t do top-down planning. You can’t plan a perfect city, and you can’t plan the kind of coordination that an anthill has.

I hope that the book isn’t taken as an argument purely against planning. There certainly are situations where top-down solutions are excellent and appropriate, but I think that there are a hundred thousand books written about top-down solutions to things and great-men theories of why things happen and “Emergence” is one of a developing, nice little library of books that are about the opposite approach.

One of the main contributions your book makes seems to be its treatment of how the Internet affects the possibilities for decentralized self-organized systems. But you also draw the distinction between the Internet/Web as a medium for such systems, and its own emergence as a decentralized system in its own right.

One of the big essential points of the book is that the basic architecture of the Web is a wonderful example of a decentralized system. But in the most elegant and most interesting systems that I look at, decentralization is only one of their characteristics. They also have to have this ability to be more adaptive and capable of learning over time, and be growing more organized over time, more useful and lifelike as they get bigger. That’s a great thing about cities; neighborhoods are a way for a city to organize its internal information. As it scales up, as it gets larger, it starts forming these clusters of useful categories of people and trades and so on; it’s almost like a giant hard drive organizing itself. The Web, left to its own devices, would be the exact opposite of that: It’s like a giant city with no neighborhoods; it needs these kind of meta-filters, these second-level kind of things, whether it is Yahoo or Google or Slashdot, to rein in that chaos and turn it to something more organized.

It needs editors?

Yeah. Editors. But what’s so interesting now are these kinds of group editors, like Slashdot, that have really flowered in the last couple of years. The idea is — OK, the Web isn’t really a truly emergent system, but we are certainly building systems on top of the architecture of the Web that are closer to emergent systems, and that is the really exciting part of it.

So the Web makes building emergent systems easier?

Absolutely.

Another point that you make is that emergent systems aren’t intrinsically “good.” On the one hand, you can show how a decentralized self-organizing structure works well for anti-globalization protesters, but at the same time it also is useful for the likes of Osama bin Laden’s network of terrorists. Is that a fair comparison?

There are a bunch of different ways in which the concepts in my book connect to current events. I’ve actually had a lot of readers write in and say, “I keep thinking about your book in the context of all this.”

There are a couple of things that happened just on the 11th that I think are connected. The first is the resilience of New York City itself, the fact that the city itself, except for a relatively small area, continued to function in its basic ways, not internally in terms of the mental lives of the people living there, but in the basic kind of functions of people moving around and garbage and all the things that a city does. It really was amazing that it all worked, despite having the worst terrorist attack in the history of the country.

It was an interesting thing to watch, and people were very inclined to chalk that up to the resilience of the New York spirit or Giuliani, to really personify it in some way, but a major factor was the kind of system the city is. There isn’t a center here; the city is a centralized system in space, but in terms of function it’s very decentralized. They hit as close to the heart of the city as you could hit, in a way, but you can’t really shut down a city, because it is so distributed in all its forces and roles and responsibilities.

Then you get to al-Qaida and the concern that people are starting to voice — I’m seeing it a little bit more and more — is that it’s comforting in a funny way, in a kind of inverted way, to make bin Laden the center of everything. You want to have the poster boy for evil, but it may be misleading in the sense that what we are dealing with here is a network of distributed cells that is powerful precisely because it doesn’t need leaders.

It’s been fascinating, I think, to watch [Secretary of Defense Donald] Rumsfeld in these press conferences. He has struck me as being very intellectually agile about some of these things in a way that perhaps I wouldn’t have expected. The other day he gave this little speech, where if you had just dropped into it you might have thought it was a chaos theory seminar. He said, he literally said, this is going to be a “nonlinear war” and it may be difficult for our linear minds to understand. He also talks about asymmetrical battles — and it’s not just large against small, it’s kind of centralized nation against decentralized network, so I think all along at various stages and scales of this, you’ve been able to see this central battle between centralized and decentralized systems play itself out again and again.

Can we put any kind of value judgement on this? If, given the influence of mediums like the Internet, that means that it is easier for decentralized self-organizing systems to flourish, what does that mean for our lives?

This is not exactly the topic of the book, but you get to the point where smaller clusters of people can have disproportionately large effects. For example, look at epidemic weapons. We could have a smallpox attack, where you just need a dense population base and suddenly a million people can be taken out by one guy with a backpack. That’s the bad news. The good news is, your odds of perishing in some kind of massively organized, state-sponsored, either internal genocide or giant war or even an influenza outbreak that happens kind of naturally, the chances of perishing in that are greatly diminished. So it’s like the good news is, your chance of being hurt or killed in some kind of mass event is greatly diminished and will continue to diminish, but if you do happen to draw the wrong straw, you are much more likely to have the blow inflicted by a small group of people rather than a nation. And you know, I’d still probably prefer those; I would love it if you didn’t have the bad news at all but that just may be the kind of bargain that we have struck.

    Ten spectacular graphic novels from 2014

    Beautiful Darkness by Fabien Vehlmann & Kerascoët
    Kerascoët's lovely, delicate pen-and-watercolor art -- all intricate botanicals, big eyes and flowing hair -- gives this fairy story a deceptively pretty finish. You find out quickly, however, that these are the heartless and heedless fairies of folk legend, not the sentimental sprites beloved by the Victorians and Disney fans. A host of tiny hominid creatures must learn to survive in the forest after fleeing their former home -- a little girl who lies dead in the woods. The main character, Aurora, tries to organize the group into a community, but most of her cohort is too capricious, lazy and selfish to participate for long. There's no real moral to this story, which is refreshing in itself, beyond the perpetual lessons that life is hard and you have to be careful whom you trust. Never has ugly truth been given a prettier face.

    Climate Changed: A Personal Journey Through the Science by Philippe Squarzoni
    Squarzoni is a French cartoonist who makes nonfiction graphic novels about contemporary issues and politics. While finishing up a book about France under Jacques Chirac, he realized that when it came to environmental policy, he didn't know what he was talking about. "Climate Changed" is the result of his efforts to understand what has been happening to the planet, a striking combination of memoir and data that ruminates on a notoriously elusive, difficult and even imponderable subject. Panels of talking heads dispensing information (or Squarzoni discussing the issues with his partner) are juxtaposed with detailed and meticulous yet lyrical scenes from the author's childhood, the countryside where he takes a holiday and a visit to New York. He uses his own unreachable past as a way to grasp the imminent transformation of the Earth. The result is both enlightening and unexpectedly moving.

    Here by Richard McGuire
    A six-page version of this innovative work by a regular contributor to the New Yorker first appeared in RAW magazine 25 years ago. Each two-page spread depicts a single place, sometimes occupied by a corner of a room, over the course of 4 billion years. The oldest image is a blur of pink and purple gases; others depict hazmat-suited explorers from 300 years in the future. Inset images show the changing decor and inhabitants of the house throughout its existence: family photos, quarrels, kids in Halloween costumes, a woman reading a book, a cat walking across the floor. The cumulative effect is serene and ravishing, an intimation of the immensity of time and the wonder embodied in the humblest things.

    Kill My Mother by Jules Feiffer
    The legendary Pulitzer Prize-winning cartoonist delivers his debut graphic novel at 85, a deliriously over-the-top blend of classic movie noir and melodrama that roams from chiaroscuro Bay City to Hollywood to a USO gig in the Pacific theater of World War II. There's a burnt-out drunk of a private eye, but the story is soon commandeered by a multigenerational collection of ferocious women, including a mysterious chanteuse who never speaks, a radio comedy writer who makes a childhood friend the butt of a hit series and a ruthless dame intent on making her whiny coward of a husband into a star. There are disguises, musical numbers and plenty of gunfights, but the drawing is the main attraction. Nobody convey's bodies in motion more thrillingly than Feiffer, whether they're dancing, running or duking it out. The kid has promise.

    The Motherless Oven by Rob Davis
    This is a weird one, but in the nervy surreal way that word-playful novels like "A Clockwork Orange" or "Ulysses" are weird. The main character, a teenage schoolboy named Scarper Lee, lives in a world where it rains knives and people make their own parents, contraptions that can be anything from a tiny figurine stashable in a pocket to biomorphic boiler-like entities that seem to have escaped from Dr. Seuss' nightmares. Their homes are crammed with gadgets they call gods and instead of TV they watch a hulu-hoop-size wheel of repeating images that changes with the day of the week. They also know their own "death day," and Scarper's is coming up fast. Maybe that's why he runs off with the new girl at school, a real troublemaker, and the obscurely dysfunctional Castro, whose mother is a cageful of talking parakeets. A solid towline of teenage angst holds this manically inventive vision together, and proves that some graphic novels can rival the text-only kind at their own game.

    NOBROW 9: It's Oh So Quiet
    For each issue, the anthology magazine put out by this adventurous U.K.-based publisher of independent graphic design, illustration and comics gives 45 artists a four-color palette and a theme. In the ninth issue, the theme is silence, and the results are magnificent and full of surprises. The comics, each told in images only, range from atmospheric to trippy to jokey to melancholy to epic to creepy. But the two-page illustrations are even more powerful, even if it's not always easy to see how they pertain to the overall concept of silence. Well, except perhaps for the fact that so many of them left me utterly dumbstruck with visual delight.

    Over Easy by Mimi Pond
    When Pond was a broke art student in the 1970s, she took a job at a neighborhood breakfast spot in Oakland, a place with good food, splendid coffee and an endlessly entertaining crew of short-order cooks, waitresses, dishwashers and regular customers. This graphic memoir, influenced by the work of Pond's friend, Alison Bechdel, captures the funky ethos of the time, when hippies, punks and disco aficionados mingled in a Bay Area at the height of its eccentricity. The staff of the Imperial Cafe were forever swapping wisecracks and hopping in and out of each other's beds, which makes them more or less like every restaurant team in history. There's an intoxicating esprit de corps to a well-run everyday joint like the Imperial Cafe, and never has the delight in being part of it been more winningly portrayed.

    The Shadow Hero by Gene Luen Yang and Sonny Liew
    You don't have to be a superhero fan to be utterly charmed by Yang and Liew's revival of a little-known character created in the 1940s by the cartoonist Chu Hing. This version of the Green Turtle, however, is rich in characterization, comedy and luscious period detail from the Chinatown of "San Incendio" (a ringer for San Francisco). Hank, son of a mild-mannered grocer, would like to follow in his father's footsteps, but his restless mother (the book's best character and drawn with masterful nuance by Liew) has other ideas after her thrilling encounter with a superhero. Yang's story effortlessly folds pathos into humor without stooping to either slapstick or cheap "darkness." This is that rare tribute that far surpasses the thing it celebrates.

    Shoplifter by Michael Cho
    Corinna Park, former English major, works, unhappily, in a Toronto advertising agency. When the dissatisfaction of the past five years begins to oppress her, she lets off steam by pilfering magazines from a local convenience store. Cho's moody character study is as much about city life as it is about Corinna. He depicts her falling asleep in front of the TV in her condo, brooding on the subway, roaming the crowded streets after a budding romance goes awry. Like a great short story, this is a simple tale of a young woman figuring out how to get her life back, but if feels as if it contains so much of contemporary existence -- its comforts, its loneliness, its self-deceptions -- suspended in wintery amber.

    Through the Woods by Emily Carroll
    This collection of archetypal horror, fairy and ghost stories, all about young girls, comes lushly decked in Carroll's inky black, snowy white and blood-scarlet art. A young bride hears her predecessor's bones singing from under the floorboards, two friends make the mistake of pretending to summon the spirits of the dead, a family of orphaned siblings disappears one by one into the winter nights. Carroll's color-saturated images can be jagged, ornate and gruesome, but she also knows how to chill with absence, shadows and a single staring eye. Literary readers who cherish the work of Kelly Link or the late Angela Carter's collection, "The Bloody Chamber," will adore the violent beauty on these pages.
