His focus is the long-term trends and social consequences of technology. Kelly’s new book, THE INEVITABLE: Understanding the 12 Technological Forces That Will Shape Our Future, is a grand synthesis of his thinking on where technology is heading in the next few decades, and how we can embrace it to maximize its benefits, and minimize its harms. Kevin Kelly is the founding executive editor of Wired magazine a...
Jul 15, 2016•2 hr 31 min•Transcript available on Metacast It is possible to be extremely astute about how we manage difficult decisions. With just a few mental tools we get the benefit of better outcomes along with release from agonizing about the process of deciding. Many mental tools—algorithms—developed with obligatory clarity for computers turn out to have ready application for humans facing such problems as: when to stop hunting for an apartment (or lover); how much novelty to seek; how to get rid of the right stuff; how to allot scarce time; how ...

You’re told you can eat it any time, but if you wait a little while, you’ll be given two marshmallows to eat. The kids who have the self-control to pass this most famous of psychological tests turn out to have more rewarding and productive lives. Walter Mischel, who first ran the test in the 1960s, spent the rest of his career exploring how self-control works, summarized in his 2014 book...
May 03, 2016•1 hr 27 min•Transcript available on Metacast No one thinks longer, or bigger, than astrophysicists. “This is the golden age of cosmology,” says Priya Natarajan, one of the world’s leading astrophysicists, because data keeps pouring in to vet even the most radical theories. And the dominant mysteries are profound. She observes that “The vast majority of stuff in the universe—both dark matter and dark energy, which dominate the content and fate of the universe—is unknown.“ The universe’s greatest exotica are the focus of her research—dark ma...
Apr 12, 2016•2 hr 32 min•Transcript available on Metacast Three billion people—nearly half of us--depend on rice for survival. What if you could adjust rice genetically so 1) it has a 50% greater yield, 2) using half the water, 3) needing far less fertilizer, 4) along with higher resilience to climate change? It would transform world agriculture. All you need to do is switch rice from inefficient C3 photosynthesis to the kind of C4 photosynthesis employed by corn, sugarcane, and sorghum. That switch has been made in plants 60 independent times by evolu...
Mar 15, 2016•1 hr 28 min•Transcript available on Metacast Once humans took charge of fire, fire remade humans and commenced remaking the world. “We got small guts and big heads because we could cook food,” says Stephen Pyne, the world’s leading historian of fire. “We went to the top of the food chain because we could cook landscapes. And we have become a geologic force because our fire technology has so evolved that we have begun to cook the planet.“ The understanding of wildfire as an ecological benefit got its biggest boost from Pyne’s 1982 landmark ...
Feb 10, 2016•1 hr 25 min•Transcript available on Metacast Consider this, optimists. All the societies in the world can collapse simultaneously. It has happened before. In the 12th century BCE the great Bronze Age civilizations of the Mediterranean—all of them—suddenly fell apart. Their empires evaporated, their cities emptied out, their technologies disappeared, and famine ruled. Mycenae, Minos, Assyria, Hittites, Canaan, Cyprus—all gone. Even Egypt fell into a steep decline. The Bronze Age was over. The event should live in history as one of the great...
Jan 12, 2016•1 hr 28 min•Transcript available on Metacast The pundits we all listen to are no better at predictions than a “dart-throwing chimp,” and they are routinely surpassed by normal news-attentive citizens. So Philip Tetlock reported in his 02005 book, Expert Political Judgement—and in a January 02007 SALT talk. It now turns out there are some people who are spectacularly good at forecasting, and their skills can be learned. Tetlock discovered them in the course of building winning teams for a tournament of geopolitical forecasting run by IARPA—...
Nov 24, 2015•2 hr 35 min•Transcript available on Metacast Infrastructure decisions—and failures to decide—affect everything about a society for centuries. That long shadow, James Fallows points out, is what makes the decisions so difficult, because "We must choose among options whose consequences we can't fully anticipate.” What we do know is that infrastructure projects are hugely disruptive and expensive in the short term, and neglecting to deal with infrastructure is even more disruptive and expensive in the long term. What would a healthy civilizat...
Oct 07, 2015•1 hr 21 min•Transcript available on Metacast So far we are trying to deal with climate change at the wrong time scale. A really deep problem cannot be solved by shallow innovations, no matter how clever. The scale of climate change requires thinking and acting in multi-decade terms at the level of infrastructure—personal as well as societal. Get it right, and “the result can be like living in a beautifully managed garden.” Saul Griffith is an inventor and meta-inventor, currently founder of Otherlabs in San Francisco (devising such things ...

MIT Planetary Scientist Sara Seager is working on the tool. She is chair of the NASA team developing a “Starshade” that would allow a relatively rudimentary space telescope to observe Earth-size planets directly, which would yield atmospheric analysis, which would determine a planet’s life-worthiness. Despite 1,000-plus exoplanet discoveries by the Kepler spacecraft and the hu...

Preternaturally eloquent, Neil Gaiman has told stories in every medium—graphic novels (The Sandman), novels (The Ocean at the End of the Lane; American Gods), short stories (Trigger Warning), children’s books (The Graveyard Book), television (Dr Who), the occasional song ("I Google You", with Amanda Palmer), an...
Jun 10, 2015•2 hr 43 min•Transcript available on Metacast Beth Shapiro is far from a giddy enthusiast about de-extinction. She knows more than nearly anyone about the subject because she is a highly regarded biologist in the middle of the two leading efforts in the new field—to resurrect extinct woolly mammoths and passenger pigeons. She knows exactly how challenging the whole process will be and how imperfect the later stages of success might appear. An evolutionary biologist who created and runs the paleogenomics lab at UC Santa Cruz, Shapiro is a ca...

Apr 15, 2015•1 hr 26 min•Transcript available on Metacast According to futurist (and Long Now board member) Paul Saffo, the "new economy” anticipated in the late 01990s is arriving late and in utterly unexpected ways. Social media, maker culture, the proliferation of sensors, and even the 02008 market crash are merely local phenomena in a much larger shift. What unfolds in the next few years will determine the shape of the global economy for the next half-century and will force a profound rethink of economic theory. Paul Saffo teaches forecasting at St...
Apr 01, 2015•1 hr 24 min•Transcript available on Metacast The main arguments against geo-engineering (direct climate intervention) to stop global warming are: 1) It would be a massive, irreversible, risky bet; 2) everyone has to agree to it, which they won’t; 3) the unexpected side effects might be horrific; 4) once committed to, it could never be stopped. What if none of those need be true? Harvard climate expert David Keith has a practical proposal for an incremental, low-cost, easily reversible program of research and eventual deployment that builds...
Feb 18, 2015•1 hr 29 min•Transcript available on Metacast In the field of environmental progress the conflict between anecdote and statistics is so flagrant that most public understanding on the subject is upside down. We worry about the wrong things, fail to worry about the right things, and fail to acknowledge and expand the things that are going well. For decades at Rockefeller University Jesse Ausubel has assembled global data and trends showing that humanity may be entering an exceptionally Green century. The most important trend is “land-sparing”...

The answer is a planetary super-organism comprised of 4 billion mobile phones, 80 quintillion transistor chips, a million miles of fiber optic cables, and 6 billion human minds all wired together. The whole thing acts like a single organism, with its own behavior and character -- but at a scale we have little experience with. This is more than just a metaphor. Kelly takes the ...

Thousands of student bioengineers from all over the world construct new life forms and race them every year at the Giant Jamboree in Boston. iGEM has been going on for ten years (2,500 competitors this year, over 32 countries, 20,000+ alumni) and gives a peerless window into the global grassroots synthetic-biology revolution, yet the phenomenon has been largely overlooked by the media, industry, and most governments...
Sep 17, 2014•2 hr 36 min•Transcript available on Metacast The NSA’s failures are public headlines. Its successes are secret. These days America’s National Security Agency lives at the intersection of two paranoias—governmental fears of attack and citizen fears about loss of privacy. Both paranoias were exacerbated by a pair of devastating attacks—9/11 and Edward Snowden. The agency now has to evolve rapidly while managing its normal heavy traffic of threats and staying ahead of the ever-accelerating frontier of cyber capabilities. In the emerging era o...
