About this Seminar:

Egypt’s pharaonic civilization rose on the Nile, but it was rooted in the deep Saharan desert and pushed by climate change, says Stefan Kröpelin.

Described in Nature magazine as “one of the most devoted Sahara explorers of our time,” Kröpelin has survived every kind of desert hardship to discover the climate and cultural history of northern Africa. He found that the “Green Sahara” arrived with monsoon rains 10,500 years ago, and people quickly moved into the new fertile savannah. There they prospered as cattle pastoralists—their elaborate rock paintings show herds of rhinoceros and scenes of prehistoric life—until 7,300 years ago, when gradually increasing desiccation drove them to the Nile river, which they had previously considered too dangerous for occupation.

To manage the Nile, the former pastoralists helped to invent a pharaonic state 5,100 years ago. Its 3,000-year continuity has never been surpassed.

Kröpelin, a climate scientist at the University of Cologne, is a dazzling speaker with hair-raising stories, great images, and a compelling tale about climate change and civilization.

The downtown company – a summary by Stewart Brand

The business advice that Tony Hsieh most took to heart came from an ad executive: “A great brand is a story that never stops unfolding.” With his own company, Zappos, he determined that “brand equals culture,” and made quality of culture the top corporate priority, followed by customer service, and then selling shoes and clothing. The formula worked so well that Zappos outgrew its collection of buildings in suburban Las Vegas. Time to build a campus.

Other suburban corporate campuses—Google, Nike, Apple—struck him as isolated and insular. He wondered if a company could be like New York University, embedded in downtown Manhattan, with all of its buildings and no end of urban amenities within a five-minute walk. Edward Glaeser’s book The Triumph of the City described how cities unfold forever, driven by density and intense variety, while companies all eventually go stagnant and die. Maybe immersion in a downtown could help keep his company unfolding, and maybe bringing company start-up culture to a decaying urban core could restart its vitality.

Zappos bet the company on the idea. They took over the abandoned city hall in the dead-end part of Las Vegas known as Fremont East and spent $200 million buying up nearby properties, $50 million on local small businesses, $50 million on tech start-ups, and $50 million on education, arts, and culture. Hsieh’s strategy is to increase: “Collisions” (serendipitous encounters); “Co-learning” (a community teaching itself); and “Connectedness” (density, diversity, and reasons to engage).

They built a Shipping Container Park with three stories of shops, amusements, and tech start-ups wrapped around a courtyard for food, play, and hanging out. They planted Burning Man mega-art on corners throughout the neighborhood “to keep you walking one more block.” Inspired by TED, the Summit Series, and especially SXSW (the South by Southwest festival in Austin), they built a theater for frequent talks and organized an annual “Life is Beautiful” music festival attracting 60,000.

Hsieh figures that “collisionability” can be quantified and designed for. He thinks that street-level interaction can be made so rich that it compensates for the lower density of low-rise buildings, with 100 residents/acre. Thus he blocked off the skyway from Zappos’s parking lot to its headquarters in the city hall. Use the street. Make street activities really attractive. Active residents, he calculates, will experience 1,000 collisionable hours a year (3.6 hours/day, 7 days/week, 40 weeks/year). Ditto for “purposeful visitors” (12 hours/day, 7 days/week, 12 weeks/year)—you are invited to be one.

If Zappos helps foster an urban “culture of openness, collaboration, creativity, and optimism,” Hsieh says, then the city can prosper, and the company with it, and both can keep unfolding their stories indefinitely.

Nicholas Negroponte: Beyond Digital – A Seminar Flashback

Posted on Wednesday, May 7th, 02014 by Mikl Em

In April 02013 Nicholas Negroponte went Beyond Digital for Long Now’s Seminar audience. Twice a month we highlight a Seminar About Long-term Thinking (SALT) from our archives.

Video of the 12 most recent Seminars is free for all to view. Beyond Digital is a recent SALT talk, free for public viewing until late May 02014. SALT audio is free for everyone on our Seminar pages and via podcastLong Now members can see all Seminar videos in HD. 

 From Stewart Brand’s summary of this Seminar (in full here):

As the world goes digital, Negroponte noted, you see pathologies of left over “atoms thinking.” Thus newspapers imagine that paper is part of their essence, telecoms imagine that distance should cost more, and nations imagine that their physical boundaries matter. “Nationalism is the biggest disease on the planet,” Negroponte said. “Nations have the wrong granularity. They’re too small to be global and too big to be local, and all they can think about is competing.” He predicted that the world is well on the way to having one language, English.

Nicholas Negroponte founded the MIT Media Lab and the One Laptop per Child Association. He is author of Being Digital and was the first investor in Wired magazine for whom he was also a regular columnist.

The Seminars About Long-term Thinking series began in 02003 and is presented each month live in San Francisco. The series is curated and hosted by Long Now’s President Stewart Brand. Seminar audio is available to all via podcast. Everyone can watch full video of the last 12 Long Now Seminars. That includes this Seminar video until late May 02014. Long Now members can watch the full ten years of Seminars in HD. Membership levels start at $8/month and include lots of benefits. You can join Long Now here.

Sylvia Earle & Tierney Thys Seminar Primer

Posted on Tuesday, May 6th, 02014 by Charlotte Hajer

undersea4National Geographic Explorers-in-Residence Sylvia Earle & Tierney Thys are among the world’s leading champions of ocean conservation. Through research, writing, and public outreach, they raise awareness of the ocean’s myriad beauties – and its vital importance to all life on the planet.

Sylvia-Earle_cKipEvans_0263_sml-300x200Sylvia Earle is a pioneer in the field of ocean conservation and marine engineering. She is the founder of Deep Ocean Engineering and Deep Ocean Exploration and Research, companies that develop the tools required for deep ocean exploration – from robotic submersibles to specialized lighting and cameras. She holds a PhD in marine biology from Princeton, has served on the National Advisory Committee on Oceans and Atmosphere, and was appointed chief scientist at the National Oceanic and Atmospheric Administration (NOAA) in 01990 – becoming the first woman to hold that post. Her publications number more than 190, and include both academic articles and children’s books about the deep ocean.

Called “her deepness” by the New York Times and the New Yorker, Earle has led more than 100 diving expeditions and logged more than 7,000 hours under water. She set a depth record of 1,250 feet in a 01979 solo dive off the coast of Oahu, and led an all-female team of aquanauts on an extended mission at an ocean-floor habitat and laboratory as part of the Tektite Program, a collaboration between NASA, GE, and the Navy to examine the biological and psychological effects of long-term isolation in small spaces.

Earle has led a number of Sustainable Seas Expeditions with the NOAA, and has pursued the establishment of protected areas in the ocean as a National Geographic Explorer-in-Residence. She won a TED prize in 02009 for her wish that people

would use all means at [their] disposal – films, expeditions, the web, new submarines – and campaign to ignite public support for a global network of marine protected areas; Hope Spots large enough to save and restore the ocean, the blue heart of the planet. How much? Some say 10 percent, some say 30 percent. You decide: how much of your heart do you want to protect? Whatever it is, a fraction of one percent is not enough. My wish is a big wish, but if we can make it happen, it can truly change the world, and help ensure the survival of what actually — as it turns out — is my favorite species; that would be us. For the children of today, for tomorrow’s child: as never again, now is the time.

She founded Mission Blue in order to pursue that wish of establishing “hope spots” – protected areas that can serve as the “seeds of tomorrow’s healthy ocean:”

Networks of marine protected areas maintain healthy biodiversity, provide a carbon sink, generate life-giving oxygen, preserve critical habitat and allow low-impact activities like ecotourism to thrive. They are good for the ocean, which means they are good for us.

t2cameraEarle has long been a mentor to Tierney Thys, whom National Geographic describes as “the next generation’s champion of ocean exploration.” A Marine biologist, Thys has devoted her career to the Mola mola, or giant ocean sunfish. Enchanted with the ocean from a young age, she began working with Earle at Deep Ocean Engineering before obtaining a doctorate in zoology at Duke, specializing in the biomechanics of swimming muscles in fish.

Today Thys is a leading expert on the ocean sunfish, a very large yet mostly unknown open ocean fish. Her research team tags the creatures and collects tissue samples in efforts to learn more about their reproductive habits, their use of ocean currents to travel across the world, their jellyfish diet, and the size of their population. In a 02003 TED talk, Thys explains what the Mola mola might teach us about life in the open ocean, and shows that marine research can awaken a love for the ocean in all of us.

I don’t think I could say it any better than the immortal Bard himself: “One touch of nature makes the whole world kin.” And sure, it may be just one big old silly fish, but it’s helping. If it’s helping to unite the world, I think it’s definitely the fish of the future.

Thys is also an educator and filmmaker: she works with nonprofits and research institutes to advance public understanding of science and the environment through films. She has written, narrated, and produced documentaries about the ocean and global environmental change with the Sea Studios Foundation, where she was the Director of Research until 02008, as well as TED Ed.

Earle and Thys both work to raise public awareness of the oceans and the vital role they play in sustaining life on the planet. As Earle writes in the Huffington Post,

Human beings are sea creatures, dependent on the ocean just as much as whales, herring or coral reefs. The big blue area that dominates the view of earth from space was once our home and today represents 97 percent of the biosphere where life exists, providing the water we drink and the air we breathe. And we are destroying it.

The two will meet on stage at the SFJAZZ Center on May 20th to lead their audience on a journey into the world’s oceans. They will explore the mysteries of the life it holds, discuss the ways we are threatening its health, and review what humanity can do to protect its well-being. You can reserve tickets, get directions, and sign up for the podcast on our Seminar page.

About this Seminar:

Land animals on an ocean planet, we have a lot to learn about how the world works. The microbes of the sea are Earth’s dominant life form. Ocean currents and temperatures drive climate and weather. Come ride a current to view bad news (dead zones, rising sea levels, melting sea ice, acidification, coral bleaching, fish piracy and overfishing) and good news (marine protected areas, functional ecosystems, megafaunal migrations, mid-Atlantic ridge, community involvement, citizen scientists) and continuing mysteries. Land is mercurial. Ocean abides.

Two of the most eloquent voices of ocean science are Sylvia Earle and Tierney Thys. Both are National Geographic Explorers, both are stars of the TED stage. They have collaborated on original and adventurous research. For this talk they are collaborating to tell (and show) sea stories of deep waters, the deep past, and the deep future.

Long Short: Burning Man Timelapse

Posted on Thursday, April 24th, 02014 by Andrew Warner
link   Categories: Long Shorts, Seminars   chat 0 Comments

Before each of our SALT talks, we show what we call a “Long Short”, a short film that exemplifies long-term thinking. We pick films that are thematically related to the Seminar of the evening, yet don’t have too much overlap with the main content. For Tuesday’s Seminar, we hosted Tony Hsieh, CEO of Zappos and instigator of the Downtown Project, a $350 million dollar project to revitalize downtown Las Vegas.

For our Long Short, we showed a video by Jason Phipps, a videographer based out of Auburn, California. Here are his own words on how the film was created:

This video captures Burning Man 2013 from an elevation of 5495 feet above sea level and over 4 linear miles from the center of Black Rock City. Old Razorback, aka Trego Peak, provides a unique vista of this incredible annual event. Climbing to the peak of Old Razorback has become a challenging and rewarding tradition for our team. This is a view that most will never experience in person. It is our passion to share it with the world through the lens of a camera. Climbing 1,888 feet in less than a mile over steep, unstable mountainside is a dangerous and exhilarating mission. This year we deployed cameras during the build week, capturing the growth of the city and ending it the night of the burn. We express gratitude to the family and friends that joined us for this epic climb. We could not do it alone. Many thanks to our team this year: Mark Phipps, John Phipps, Dallon Phipps, Kevin Johnson & Meghan Johnson. We also offer heartfelt thanks to OpenOptics (Inspired Flight) and Dusty Nix for designing such an incredible sound score for this year’s rendition.

Steven Johnson: The Long Zoom – A Seminar Flashback

Posted on Tuesday, April 22nd, 02014 by Mikl Em
link   Categories: Seminars   chat 0 Comments

In May 02007 author Steven Johnson spoke for Long Now about The Long Zoom, which is his take on how humans integrate perspectives at different scales for both pleasure and practical reasons. He explains this “zoom” in everything from computer games to ending the cholera epidemic in 19th century London. That last topic, the subject of his book The Ghost Map, serves as a leaping off point for this Seminar.

Twice a month we highlight a Seminar About Long-term Thinking (SALT) from our archives. Long Now members can watch this video here. The audio is free for everyone on the Seminar page and via podcast. Long Now members can see all Seminar videos in HD. Video of the 12 most recent Seminars is also free for all to view.

In his introduction Stewart Brand calls Johnson a polymath, and this talk is a truly polymathic display across disciplines, history, and literature. But it’s also easy to follow because much of it takes place in the realm of current pop culture: from the TV show Lost to the games SimCity and Spore. Even Johnson’s revisiting of London’s 01800′s brings with it insights into the history of infographics.

Steven Johnson

The talk itself is a zoom and Johnson shows implicitly that integrating perspectives is useful, and pleasurable, to the way human minds work today. New research on gaming and the brain, the history of detective fiction, and the UI of World of Warcraft are all side trips on Johnson’s guided tour to how the Long Zoom, both as a practical tool and an entertainment principle, can lead to consilience.

From Stewart’s summary of this Seminar (in full here):

Johnson proposed that another word for the long zoom perspective is “consilience”— a fine old word, revived by Edward O. Wilson, that links multiple disciplines and multiple levels into a whole body of knowledge with extra benefits the separate disciplines lack. Science and culture can blend rigorously. What is discovered in consilience is not just scales of distance or time but nested systems.

Steven Johnson is the author of eight books which cover topics in science, technology, history and popular culture including EmergenceEverything Bad Is Good for You and most recently Future Perfect.

The Seminars About Long-term Thinking series began in 02003 and is presented each month live in San Francisco. The series is curated and hosted by Long Now’s President Stewart Brand. Seminar audio is available to all via podcast.

Government as radical, patient VC – a summary by Stewart Brand

The iPhone, Mazzucato pointed out, is held up as a classic example of world-changing innovation coming from business.

Yet every feature of the iPhone was created, originally, by multi-decade government-funded research. From DARPA came the microchip, the Internet, the micro hard drive, the DRAM cache, and Siri. From the Department of Defense came GPS, cellular technology, signal compression, and parts of the liquid crystal display and multi-touch screen (joining funding from the CIA, the National Science Foundation, and the Department of Energy, which, by the way, developed the lithium-ion battery.) CERN in Europe created the Web. Steve Jobs’ contribution was to integrate all of them beautifully.

Venture Capitalists (VCs) in business expect a return in 3 to 5 years, and they count on no more than one in ten companies to succeed. The time frame for government research and investment embraces a whole innovation cycle of 15 to 20 years, supporting the full chain from basic research through to viable companies. That means they can develop entire new fields such as space technology, aviation technology, nanotechnology, and, hopefully, Green technology.

But compare the reward structure. Government takes the greater risk with no prospect of great reward, while VCs and businesses take less risk and can reap enormous rewards. “We socialize the risks and privatize the rewards.” Mazzucato proposes mechanisms for the eventual rewards of deep innovation to cycle back into a government “innovation fund”—perhaps by owning equity in the advantaged companies, or retaining a controlling “golden share” of intellectual property rights, or through income-contingent loans (such as are made to students). “After Google made billions in profits, shouldn’t a small percentage have gone back to fund the public agency (National Science Foundation) that funded its algorithm?” In Brazil, China, and Germany, state development banks get direct returns from their investments.

The standard narrative about government in the US is that it stifles innovation, whereas the truth is that it enables innovation at a depth that business cannot reach, and the entire society, including business, gains as a result. “We have to change the way we think about the state,” Mazzucato concludes.

Tony Hsieh Seminar Primer

Posted on Tuesday, April 8th, 02014 by Charlotte Hajer
link   Categories: Seminars   chat 0 Comments

Tony Hsieh is perhaps best known as a successful Silicon Valley entrepreneur. He founded and then sold LinkExchange in the late 01990s, before going on to become CEO of online retail giant Zappos. But what Hsieh really does is build communities. Corporate tech is, for him, primarily a way to bring people together and foster a culture of togetherness. Any business, Hsieh is known to argue, should be evaluated not (just) on its return on investment, but on its ROC – its return on community.

Growing up in the Bay Area, Hsieh revealed an entrepreneurial spirit at an early age. In elementary and high school, he experimented with a variety of money-making ventures – from failed attempts to start a profitable worm farm to a successful mail-order button-making business – and as a Harvard undergrad, he managed an on-campus pizzeria. After graduating with a degree in computer science, the founding of LinkExchange was a logical next step. The company, an online advertising cooperative, became wildly successful: two years after its launch, it sold to Microsoft for several hundreds of millions of dollars. Hsieh, however, hadn’t much cared for the corporate lifestyle and profits-oriented culture at LinkExchange. So when he became involved with Zappos – first as an early investor, soon after as CEO – he set out to do things differently.

imgres-1Hsieh puts a lot of heart and effort into the creation of a positive corporate culture. Not only is “service” the number one commandment in Zappos’ oft-cited code of conduct; other items encourage “open and honest relationships,” “family spirit,” and even “fun and a little weirdness.” The company’s quarterly all-hands meetings are reported to be celebratory events full of music performances, employee skits, and bold stunts. Instead of traditional job titles, what you’ll find at Zappos are ‘ninjas’ and ‘monkeys’. In fact, the company recently announced that it is doing away with traditional corporate hierarchy altogether: it’s transitioning into a holacracy, an organizational structure based on principles of self-governance and a democratic distribution of power.

Fortune Magazine consistently ranks Zappos among the nation’s best companies to work for, and Hsieh is eager to share the positivity. In 02010, he published Delivering Happiness, an autobiography-cum-manifesto in which he shows that a focus on company culture and community wellbeing can actually lead to greater profits. The book became so popular that Hsieh and his team soon launched a company and website dedicated entirely to spreading its message.

These days, Hsieh spends much of his time pursuing his mission of community happiness in a very particular location. In downtown Las Vegas, a neighborhood of struggling casinos and weekly hotels long forgotten in the dark shadow of the glittery Strip, he’s been working on a major urban revitalization project.

The Downtown Project was born in 02011, when it became clear that Zappos was growing out of its headquarters in Henderson, Nevada, and Hsieh began to think about building a new campus for his employees. He liked the sense of community created by companies like Nike, Apple, and Facebook, but wanted to avoid the insularity that often characterized their Silicon Valley compounds. As Hsieh explains,

We started brainstorming, what’s the dream campus we can create? And we decided, rather than take this very insular approach to building a campus, let’s actually take more of an NYU-type approach, where the campus kind of blends in with the city, and so rather than focus just on Zappos, focus on the community, and then over time that’ll become this kind of self-feeding thing that will ultimately help retain and attract more employees and be good for the city as well. It’s slightly different from most development projects, in that we’re not trying to master plan from the top down, we really want it to be organic and driven by the community, and part of the goal is for us at Zappos to learn from cities how to be more innovative and scale our culture, and scale our productivity. Once you have that, then the magic just kind of happens automatically.

800px-Fremont_East_view_from_ElCortezKey in Hsieh’s vision is the notion of collisions: the idea that innovation and creativity sprout from random, unplanned, and informal encounters between people. Hsieh ultimately tries to  build companies – and now, whole communities – that are designed to maximize those collisions.

“It’s the Downtown Project’s big bet,” Hsieh says [in Wired Magazine], “that a focus on collisions, com­munity, and colearning will lead to happiness, luckiness, innovation, and pro­ductivity. It’s not even so big a bet,” he adds. “Research has been done about this on the office level. It’s just never really been applied in a consolidated way to a city revitalization project.”

Big or not, it’s a bet with $350 million riding on it. Hsieh has invested $200 million in local real estate, and $50 million each in education, small businesses, and a tech start-up fund. He’s building schools, developing parks, establishing community work spaces, and organizing arts and music festivals. Inspired by Edward Glaeser’s theories of urban vitality, Hsieh envisions the city as a kind of incubator: by bringing in promising new business and creating spaces for its entrepreneurs to ‘collide’ with one another, he hopes to spur new life and creativity. For Hsieh, innovation and community go hand in hand.

In the end, Hsieh hopes his efforts will pay off in many ways. Beyond setting up shop in Las Vegas, which offered Zappos a more favorable tax treatment, he expects that by making the city more livable it will be good for business and help him attract and retain top-tier talent.

Tony Hsieh will talk about his Downtown Project and the importance of community vitality at the SF JAZZ Center on April 22. You can reserve tickets, get directions, and sign up for the podcast on our Seminars page.

George Dyson: No Time Is There – A Seminar Flashback

Posted on Friday, April 4th, 02014 by Mikl Em
link   Categories: Seminars, Technology   chat 0 Comments

In March 02013 George Dyson spoke for Long Now about the origins of the digital universe. Dyson, an author and science historian, gave a detailed explication of the dawn of the modern computer in the 1950s at Princeton’s Institute for Advanced Study (IAS). Twice a month we highlight a Seminar About Long-term Thinking (SALT) from our archives.

SALT audio is free for everyone on our Seminar pages and via podcast. Long Now members can see all Seminar videos in HD. Video of the 12 most recent Seminars is also free for all to view.

No Time Is There: The Digital Universe and Why Things Appear To Be Speeding Up is a recent SALT talk (for a little longer). It will be free for public viewing until late April 02014.

Legends of science and mathematics like Alan Turing, Kurt Gödel, and John von Neumann feature prominently in these stories. Dyson’s remarkable historical reporting also includes first-hand observances of von Neumann’s workspace and insights gleaned from his interviews with participants at these events. His father, the theoretical physicist Freeman Dyson, went to work at IAS in 1953–the same year George was born.

Much of the early digital work was closely intertwined with the post-WWII effort to engineer better bombs.

From Stewart Brand’s summary of this Seminar (in full here):

In the few years they ran that machine, from 1951 to 1957, they worked on the most difficult problems of their time, five main problems that are on very different time scales—26 orders of magnitude in time—from the lifetime of a neutron in a bomb’s chain reaction measured in billionths of a second, to the behavior of shock waves on the scale of seconds, to weather prediction on a scale of days, to biological evolution on the scale of centuries, to the evolution of stars and galaxies over billions of years. And our lives, measured in days and years, is right in the middle of the scale of time. I still haven’t figured that out.

George Dyson, 02013 March Seminar: No Time is There

George Dyson is an author and science historian whose books include Baidarka the Kayak, Darwin Among the Machinesand Turing’s Cathedral: The Origins of the Digital Universe. This was the third time he spoke on the Long Now Seminar stage, including the 02005 SALT Talk presented with his sister Esther and their father Freeman Dyson.

Here’s a short video excerpt of this talk:

The Seminars About Long-term Thinking series began in 02003 and is presented each month live in San Francisco. The series is curated and hosted by Long Now’s President Stewart Brand. Seminar audio is available to all via podcast.
