Eric Cline: 1177 B.C.: When Civilization Collapsed
### When chaos overwhelmed civilization
Archaeologist Cline began by declaring that the time he would most like to be transported to is the Late Bronze Age in the Mediterranean—the five centuries between 1700 and 1200 B.C. In those centuries eight advanced societies were densely connected—Egyptians, Assyrians, Babylonians, Canaanites, Hittites, Cypriots, Minoans, and Mycenaeans. They grew to power over two millennia, but they collapsed simultaneously almost overnight. What happened?
The density of their connection can be learned from trade goods found in shipwrecks, from Egyptian hieroglyphs and wall paintings, and from countless well-preserved clay-tablet letters written between the states. The tin required for all that bronze (tin was the equivalent of oil today) came from Afghanistan 1,800 miles to the east. It was one of history’s most globalized times.
In the 12th Century B.C. everything fell apart. For Cline the defining moment was the battle in 1177 B.C. (8th Year of Ramses III) when Egypt barely defeated a mysterious army of “Sea Peoples.” Who were they? Do they really explain the general collapse, as historians long assumed?
Cline thinks the failure was systemic, made of a series of cascading calamities in a highly interdependent world. There were indeed invasions—they might have been soldiers, or refugees, or civil war, or all three. But the violence was probably set in motion by extensive drought and famine reported in tablet letters from the time. Voices in the letters: “There is famine in our house. We will all die of hunger.” “Our city is sacked. May you know it!” In some regions there were also devastating earthquakes.
The interlinked collapses played out over a century as central administrations failed, elites disappeared, economies collapsed, and whole populations died back or moved elsewhere.
In the dark centuries that followed the end of the Bronze Age, romantic myths grew of how wondrous the world had once been. Homer sang of Achilles, Troy, and Odysseus. Those myths inspired the Classical Age that eventually emerged.
Cline wonders, could the equivalent of the Bronze Age collapse happen in our current Age?

Philip Tetlock: Superforecasting
### All it takes to improve forecasting is KEEP SCORE
Will Syria’s President Assad still be in power at the end of next year? Will Russia and China hold joint naval exercises in the Mediterranean in the next six months? Will the Oil Volatility Index fall below 25 in 2016? Will the Arctic sea ice mass be lower next summer than it was last summer?
Five hundred such questions of geopolitical import were posed in tournament mode to thousands of amateur forecasters by IARPA—the Intelligence Advanced Research Projects Activity--between 2011 and 2015. (Tetlock mentioned that senior US intelligence officials opposed the project, but younger-generation staff were able to push it through.) Extremely careful score was kept, and before long the most adept amateur “superforecasters” were doing 30 percent better than professional intelligence officers with access to classified information. They were also better than prediction markets and drastically better than famous pundits and politicians, who Tetlock described as engaging in deliberately vague “ideological kabuki dance."
What made the amateurs so powerful was Tetlock’s insistence that they score geopolitical predictions the way meteorologists score weather predictions and then learn how to improve their scores accordingly. Meteorologists predict in percentages—“there is a 70 percent chance of rain on Thursday.” It takes time and statistics to find out how good a particular meteorologist is. If 7 out of 10 such times it in fact rained, the meteorologist gets a high score for calibration (the right percentage) and for resolution (it mostly did rain). Superforecasters, remarkably, assigned probability estimates of 72-76 percent to things that happened and 24-28 percent to things that didn’t.
How did they do that? They learned, Tetlock said, to avoid falling for the “gambler’s fallacy”—detecting nonexistent patterns. They learned objectivity—the aggressive open-mindedness it takes to set aside personal theories of public events. They learned to not overcompensate for previous mistakes—the way American intelligence professionals overcompensated for the false negative of 9/11 with the false positive of mass weapons in Saddam’s Iraq. They learned to analyze from the outside in—Assad is a dictator; most dictators stay in office a very long time; consider any current news out of Syria in that light. And they learned to balance between over-adjustment to new evidence (“This changes everything”) and under-adjustment (“This is just a blip”), and between overconfidence ("100 percent!”) and over-timidity (“Um, 50 percent”). “You only win a forecasting tournament,” Tetlock said, “by being decisive—justifiably decisive."
Much of the best forecasting came from teams that learned to collaborate adroitly. Diversity on the teams helped. One important trick was to give extra weight to the best individual forecasters. Another was to “extremize” to compensate for the conservatism of aggregate forecasts—if everyone says the chances are around 66 percent, then the real chances are probably higher.
In the Q & A following his talk Tetlock was asked if the US intelligence community would incorporate the lessons of its forecasting tournament. He said he is cautiously optimistic. Pressed for a number, he declared, “Ten years from now I would offer the probability of .7 that there will be ten times more numerical probability estimates in national intelligence estimates than there were in 2005.”
Asked about long-term forecasting, he replied, “Here’s my long-term prediction for Long Now. When the Long Now audience of 2515 looks back on the audience of 2015, their level of contempt for how we go about judging political debate will be roughly comparable to the level of contempt we have for the 1692 Salem witch trials."

James Fallows: Civilization's Infrastructure
### Infrastructure investment tricks
All societies under-invest in their infrastructure—in the systems that allow them to thrive. There is hardware infrastructure: clean water, paved roads, sewer systems, airports, broadband; and, Fallows suggested, software infrastructure: organizational and cultural practices such as education, safe driving, good accounting, a widening circle of trust. China, for example, is having an orgy of hard infrastructure construction. It recently built a hundred airports while America built zero. But it is lagging in soft infrastructure such as safe driving and political transition.
Infrastructure always looks unattractive to investors because the benefits: 1) are uncertain; 2) are delayed; and 3) go to others—the public, in the future. And the act of building infrastructure can be highly disruptive in the present. America for the last forty years has starved its infrastructure, but in our history some highly controversial remarkable infrastructure decisions got through, each apparently by a miracle—the Louisiana Purchase, the Erie Canal, the Gadsden Purchase, the Alaska Purchase, National Parks, Land Grant colleges, the GI Bill that created our middle class after World War II, and the Interstate highway system.
In Fallows’ view, the miracle that enabled the right decision each time was either an _emergency_ (such as World War II or the Depression), _stealth_ (such as all the works that quietly go forward within the military budget or the medical-industrial complex), or a _story_ (such as Manifest Destiny and the Space Race). Lately, Fallows notes, there is a little noticed infrastructure renaissance going in some mid-sized American cities, where the political process is nonpoisonous and pragmatic compared to the current national-level dysfunction.
By neglecting the long view, Fallows concluded, we overimagine problems with infrastructure projects and underimagine the benefits. But with the long view, with the new wealth and optimism of our tech successes, and expanding on the innovations in many of our cities, there is compelling story to be told. It might build on the unfolding emergency with climate change or on the new excitement about space exploration. Responding to need or to opportunity, we can tell a tale that inspires us to reinvent and build anew the systems that make our society flourish.

Saul Griffith: Infrastructure and Climate Change
## Green infrastructure
Griffith began with an eyeroll at the first round of responses in the US to reducing greenhouse gases, a program he calls “peak Al Gore.” Some activities feel virtuous —becoming vegetarian, installing LED lights, avoiding bottled water, reading news online, using cold water detergent, and “showering less in a smaller, colder house”—but they demand constant attention and they don’t really add up to what is needed.
Griffith’s view is that we deal best with greenhouse gases by arranging our infrastructure so we don’t have to think about climate and energy issues every minute. Huge energy savings can come from designing our buildings and cars better, and some would result from replacing a lot of air travel with “video conferencing that doesn’t suck.“ Clean energy will mostly come from solar, wind, biofuels (better ones than present), and nuclear. Solar could be on every roof. The most fuel-efficient travel is on bicycles, which can be encouraged far more. Electric cars are very efficient, and when most become self-driving they can be lighter and even more efficient because “autonomous vehicles don’t run into each other.” Sixty percent of our energy goes to waste heat; with improved design that can be reduced radically to 20 percent.
Taking the infrastructure approach, in a few decades the US could reduce its total energy use by 40 percent, while eliminating all coal and most oil and natural gas burning, with no need to shower less.

Sara Seager: Other Earths. Other Life.
## To find living exoplanets
Thanks to recent exoplanet research, Seager began, we now know that nearly all of our galaxy’s 300 billion stars are accompanied by planets, and a unexpectedly high number of them are rocky like Earth, and many of those orbit in a “habitable” range—meaning that they could harbor liquid water and perhaps life. How can we detect that life?
(To learn about the 4,700-plus planets so far discovered, Seager recommended an exciting dynamic map and encyclopedia from NASA called “[Eyes on Exoplanets](http://eyes.jpl.nasa.gov/eyes-on-exoplanets.html).” Seager predicts that “If an Earth 2.0 exists, we have the capability to find and identify it by the 2020s.”)
The way to discover life from a distance is to search for spectrographic evidence of “biosignature gases” such as oxygen or methane in the planetary atmosphere. To do that we have to acquire direct imaging of the rocky planets, but we can’t because our telescopes are blinded by the brilliance of the planet’s star, a billion times brighter than the planet. “It’s like looking for a firefly next to a searchlight, from thousands of miles away,” Seager said. Even the next planet-discovery telescope, called TESS (Transiting Exoplanet Survey Satellite), which is coming in 2018, will not be able to study exoplanet atmospheres.
The solution that Seager has been working on is called [Starshade](http://planetquest.jpl.nasa.gov/video/15). To perfectly occult a star with a perfectly dark, hard-edged shadow, it will be deployed tens of thousands of kilometers from its telescope. It will be a disk 15 to 20 meters in diameter, with a perimeter of exotically shaped “petals” to defeat the effect of light diffracting around the edges of the disk. The edges have to be geometrically exact and machined to razor sharpness. The Starshade would fly in formation with a telescope located at the stable Lagrange point called L2, a million miles from Earth in the direction away from the Sun. The cost, including launch, will be about $650 million—not currently budgeted by NASA.
Now that we know planets are extremely common, one of the profoundest questions is whether life is also common in our galaxy, or is it extremely rare? Seager thinks that life abounds out there, and we will be able to point to examples in this century.

Ramez Naam: Enhancing Humans, Advancing Humanity
### Enhancing humans and humanity
Beginning with the accelerating pace of biotech tools for human health and enhancement, Naam noted that health issues such as disease prevention will be drastically easier to implement than enhancement. Preventing some hereditary diseases can be done with a single gene adjustment, whereas enhancement of traits like intelligence or longevity entails the fine tuning of hundreds of genes. He favors moving ahead with human germline engineering to totally eliminate some of our most horrific diseases.
Over time he expects that human gene editing will lead in the opposite direction from the enforced conformity depicted in _Brave New World_ and the film “Gattaca.” Instead people will relish exploring variety, and the plummeting costs of the technology will mean that the poor will benefit as well as the rich.
Naam’s brain discussion began with the Sergey Brin quote, “We want Google to be the third half of your brain.” Brain interface tools are proliferating. There are already 200,000 successful cochlear implants which feed sound directly into the nervous system. There is a digital eye that feeds pretty good visual data directly to the brain via a jack in the side of the user’s head. There is a hippocampus chip that can restore brain function in a rat.
Rat brains have been linked so that what one rat learns, the other rat knows. The paper on that work was titled “Meta-organism of Two Rats on the Internet.” Humans also have been linked brain to brain at a distance to share function. Zebrafish have been lit up to show all their neurons firing in real time. Coming soon is the deployment of “neural dust” that can provide ultrasonic communications with tens of thousands of neurons at a time.
How profound are the ethical issues? Naam observed that we already have many of the attributes of telepathy in our cell phones and smart phones. They came so rapidly and cheaply that they erased most of the concerns about a “digital divide.” Half of the world is now on the Internet, with the rest coming fast. And rather than a divider, the technology proved to be an equalizer and a connector, fostering economic growth and the rapid spread and sifting of ideas.
Digital connectivity, he argued, is widening everyone’s “circle of empathy.” A viral video started the Arab Spring. Viral videos are changing how everyone thinks about race in America. These technologies, he concluded, are making humans more humane.
One question from the audience inquired about the origin of so much reference in the Nexus series to group meditation as the epitome of mind sharing. Naam noted that Buddhists, including the Dalai Lama, are highly interested in brain science, and his own experiences of the ecstacy of mind sharing were at a rave at Burning Man and a ten-day Vipassana Meditation Retreat in Thailand.
I asked if he agreed with the current round of panic about superintelligent artificial intelligence posing an existential threat to humanity. He said no. The dark scenarios imagine an AI so smart it implements new and grotesquely harmful pathways to solve a poorly contextualized problem. Naam pointed out that “Software almost never does anything well by accident.” (A flock of Tweets burst from the theater with that line.) And the dark scenarios imagine an isolated rogue super-capable AI. In reality nothing really capable is developed in isolation.

Neil Gaiman: How Stories Last
## How stories last
Stories are alive. The ones that last, Gaiman said, outcompete other stories by changing over time. They make it from medium to medium—from oral to written to film and beyond. They lose uninteresting elements but hold on to the most compelling bits or even add some. The most popular version of the Cinderella story (which may have originated long ago in China) has kept the gloriously unlikely _glass_ slipper introduced by a careless French telling.
“Stories,” Gaiman said, “teach us how the world is put together and the rules of living in the world, and they come in an attractive enough package that we take pleasure from them and want to help them propagate.” Northwest coast native Americans have a tale about a beautiful woman and young man whose forbidden love was punished by the earth shaking, and black ash on snow, and finally fire coming from a mountain, killing many people. It stopped only when the beautiful woman was thrown into the burning mountain.
That is important information-- solid-seeming mountains can suddenly erupt, and early warnings of that are earthquakes and ash. As pure information it won’t last beyond three generations. But add in beauty and forbidden love and tragic death, and the story will be told as long as people live in the mountains.
The first emperor of China died 2,300 years ago. He was so powerful that he was able to totally conceal the location of his tomb, and all that was left was stories about the fabulous treasures buried with him. There was said to a whole army of terracotta warriors and ships floating on lakes of mercury. A few years ago a terracotta warrior was dug up in a field in China, and then a whole army of them. Archaeologists figured out where the emperor’s mausoleum must be buried, but first they did something not normally done at archeological digs. They checked if there might be any incredibly poisonous mercury around. There is.
Gaiman said he learned something important about stories from his cousin Helen Fagin, a Holocaust survivor who taught class in a Polish ghetto during the Nazi occupation. Books were forbidden on pain of death, but Helen had a Polish translation of _Gone With the Wind_ she read at night, and she told its story to her entranced students by day. “The magic of escapist fiction,” Gaiman said, “is that it can offer you escape from an otherwise intolerable situation, and it can furnish you with armor, knowledge, weapons, and other tools you can take back into your life to make it better.”
“‘Once upon a time,’ Gaiman said, “is code for ‘I’m lying to you.’ We experience stories as lies and truth at the same time. We learn to empathize with real people via made-up people. The most important thing that fiction does is it lets us look out through other eyes, and that teaches us empathy—that behind every pair of eyes is somebody like us.“
Stories have their own form of life, Gaiman concluded. “You can view people as this peculiar byproduct that stories use for breeding and transmission. They are symbiotic with us. They are the thing that we have used since the dawn of humanity to become more than just one person.“

Beth Shapiro: How to Clone a Mammoth
## De-extinction science
When people hear about “ancient DNA” in fossils, Shapiro began, the first question always is “Can we clone a dinosaur?” Dinosaurs died out so many millions of years ago, their fossils are nothing but rock (and by the way, there’s no workaround with mosquitoes in amber because amber totally destroys DNA). With no DNA, there’s no chance of cloning a dinosaur. (Sorry.)
The fossils of woolly mammoths, though, are not rock. They died out only thousands of years ago, and their remains are pretty well preserved in frozen tundra, which means there is recoverable DNA. So, Plan A, can we clone a mammoth? It would be like Dolly-the-sheep, where you take nuclear DNA from somewhere in the preserved mammoth body, inject it into the egg of a closely related species (Asian elephant), plant the mammoth embryo in a surrogate mother, and in two years, a newborn woolly mammoth! But as soon as any animal dies, unless it is cyropreserved with great care, all the DNA is attacked by gut bacteria, by water, by temperature change, and soon you have nothing but tiny fragments. Nobody has found any intact cells or intact DNA in frozen mammoth mummies, and probably they never will. So, you can’t clone a mammoth. (Sorry.)
Okay, Plan B, can you _sequence_ a mammoth—reconstruct the entire genome through digital analysis and then rebuild it chemically and plant that in an elephant egg? Ancient DNA, even from the best specimens, is so badly fragmented and contaminated it’s hard to tell what bits are mammoth and how they go together. Using the elephant genome for comparison, though, you can do a pretty good job of approximating the original. Just last week the successful sequencing and assembly of the full woolly mammoth genome—4 billion base pairs—was announced. But all sequencing is incomplete, including the human genome, and maybe important elements got left out. A genome rebuilt from scratch won’t be functional, and you can’t create a mammoth with it. (Sorry.)
Alright, Plan C, can you _engineer_ a mammoth? Take a living elephant genome and cut and paste important mammoth genes into it so you get all the mammoth traits you want. There is an incredibly powerful new tool for genome editing called CRISPR Cas 9 that can indeed swap synthetic mammoth genes into an elephant genome, and this has been done by George Church and his team at Harvard. They swapped in 14 genes governing mammoth traits for long hair, extra fat, and special cold-adapted blood cells. _If_ you can figure out the right genes to swap, _and_ you get them all working in an elephant genome, _and_ you manage the difficult process of cross-species cloning and cross-species parenthood, _then_ you may get mammoth-like Asian elephants capable of living in the cold.
(During the Q & A, Shapiro pointed out that with birds the process is different than with mammals. Instead of cloning, you take the edited genome and inject it into primordial germ cells of the embryo of a closely related bird. If all goes well, when the embryo grows up, it has the gonads of the extinct bird and will lay some eggs carrying the traits of the extinct animal.)
Why bring back extinct animals? Certainly not to live in zoos. But in the wild they could restore missing ecological interactions. Shapiro described Sergey Zimov’s “Pleistocene Park” in northern Siberia, where he proved that a dense herd of large herbivores can turn tundra into grassland—”the animals create and maintain their own grazing environment.” The woolly mammoth was a very large herbivore. Its return to the Arctic could provide new habitat for endangered species, help temper climate change, increase the population of elephants in the world, and bring excitement and a reframed sense of what is possible to conservation.
Furthermore, Shapiro concluded, the technology of de-extinction can be applied to endangered species. Revive & Restore is working on the black-footed ferret, which has inbreeding problems and extreme vulnerability to a disease called sylvatic plague. Gene variants that are now absent in the population might be recovered from the DNA of specimens in museums, and the living ferrets could get a booster shot from their ancestors.

Michael Shermer: The Long Arc of Moral Progress
## Moral Progress
Shermer began with Martin Luther King’s statement in Selma, March 1965: “The arc of the moral universe is long, but it bends toward justice.” What if we look at that arc in terms of trendlines instead of headlines?
In the mid-19th century there were almost no democracies. Now there are 118, out of a total of 196 nations. Women’s suffrage only began to take off in the early 20th century (led in the US by Inez Milholland on her white stallion) and by the end of the century nearly all nations had adopted it (even Saudi Arabia may catch up this year). Gay rights are gaining legal and popular support in this very decade, with the transition in popular opinion about same-sex marriage arriving in 2011. Shermer noted that research shows that support is greatest in younger generations and in people associated with no religion, and that pattern is standard with most forms of moral progress.
Animal rights, Shermer said, is just now taking off in earnest, inspired by the 18th-century Enlightenment social reformer, Jeremy Bentham, who wrote, “The question is not Can they reason? nor Can they talk? but Can they _suffer_?” The Enlightenment brought the power of abstract reasoning and science to social and moral problems and provided the tools to defy the unreasoning demands of strict ideologies and religions. Voltaire declared, “Those who can make you believe absurdities can make you commit atrocities.”
Shermer ended with Martin Luther King’s observation that “we were made for the stars, created for the everlasting, born for eternity,” and that stardust—us--can come to embody morality is the long arc of moral progress.

Paul Saffo: The Creator Economy
### The Creator Economy
Media innovations drive economic shifts, Saffo began. “We invent new technology and then use it to reinvent ourselves.”
1\. The Industrial/producer Economy. At the beginning of the 20th century the leading scarcity was _stuff_ , and so manufacture was systematized. By 1914 one of Ford’s workers could buy a Model T car with four month’s salary. Production efficiency won the Second World War for the allies. In 1944 the US was producing 8 aircraft carriers a month, a plane every five minutes, and 50 merchant ships a day. The process became so efficient that its success ended the dominance of that economy. That always happens. “Every new abundance creates an adjacent scarcity.“
2\. The Consumer Economy. The new scarcity was _desire_. 1958 brought the first credit card. The CEOs of leading companies shifted from heads of production to heads of marketing. Container ships doubled global trade.
3\. The Creator Economy. In 1971 Herbert Simon predicted, “A wealth of information creates a poverty of _attention_ and a need to allocate that attention efficiently.” The new scarcity turned out to be _engagement_. The mass media television channels that had dominated the Consumer Economy were overwhelmed by personal media--YouTube, eBay, Facebook, Wikipedia, Twitter, Google, Etsy. Hollywood was overwhelmed by video games. (The blockbuster movie “Avatar“ opened in 2009 with a $73 million weekend. The previous month, the game “Call of Duty: Modern Warfare 2” sold $310 million in 24 hours.)
Mass participation became the new normal. Stuff is cheap; status comes from creation. Value is created by engagement---from Wikipedia entries to Google queries to Mechanical Turk services to Airbnb to Uber to Kaggle analyses. Burning Man sets the standard of “no spectators.” Makers insist that “If you can’t open it, you don’t own it.”
Saffo advised recalling four warnings for revolutionaries. 1) There are winners and losers. 2) Don’t confuse early results with long-term outcomes. 3) Successful insurgents become over-powerful incumbents. 4) Technologies of freedom become technologies of control.
If we want privacy now, we have to pay extra for it. As with our smart phones, we will subscribe to self-driving cars, not own them. With our every move tracked, we are like radio-collared bears. Our jobs are being atomized, with ever more parts taken over by robots. We trade freedom for convenience.
Over the 30 or so years remaining in the Creator Economy, Saffo figures that we will redefine freedom in terms of interdependence, and he closed with Richard Brautigan’s poem about a “cybernetic ecology” where we “are all watched over by machines of loving grace.”
