Tanzania alone sits on an estimated 2,222 metric tons of gold and boasts the third-highest reserves of the metal in Africa. But while the failure of these reserves to translate into wealth for ordinary people has led to populist moves – Tanzania’s President John Magufuli has demanded foreign mining firms pay higher taxes if they want to continue exporting — the problem may lie, in part, elsewhere. While women account for about 40 to 50 percent of Africa’s 8 million artisanal miners, their average income is significantly lower than that of their male counterparts, according to the African Center for Economic Transformation.

That has a spillover effect on communities. An established body of economic research, including by organizations like the Organization for Economic Cooperation and Development (OECD), has shown that economic empowerment of women translates into greater benefits for their families and communities than similar levels of earnings for men. That’s a phenomenon that groups working with gold miners in East Africa are witnessing also.

Those findings apply to a single generation, yet they tug at the edges of evolutionary theory, in which species change slowly over millennia, not rapidly over the months or years of a single life. Charles Darwin’s process of natural selection holds that nature choses the best-adapted organisms to reproduce and survive in any given ecosystem. The process operates when DNA sequences mutate randomly, and organisms with the specific sequences best-adapted to the environment multiply and prevail – causing gene expression to shift. Yet as surely as the slow march of Darwinian evolution shapes life on Earth over aeons, scientists have found that epigenetic signals can work each day, and not just through methyl groups. Experience in the environment could also alter chromatin, the molecular matrix making up our chromosomes; RNA, the messenger molecules that translate genetic instructions from DNA into protein; and histones, the proteins involved in packaging and structuring the chromatin comprising the genes.

The human brain has always loved the dopamine rush of notifications, in any form; recent research indicates the unpredictable but ubiquitous updates of Gmail or Twitter carry the same neurological effect as rocking a slot machine. While Internet use is "not addictive in the same way as pharmacological substances are," as cognitive scientist Tom Stafford noted in 2013, we continually chase those unpredictable payoffs on Facebook and Instagram in ways that tend to mirror gambling or sex addictions, even if "Internet addiction" writ large currently holds an ambiguous position in the Diagnostic and Statistical Manual of Mental Disorders.

For products whose fundamental business proposition is harnessing attention, building those so-called "compulsion loops" isn't an accident of technology—it's the whole point. Indeed, observers have argued since Parker's "human psychology" flub last year that Facebook has not just meticulously measured, but fundamentally altered human behavior, and nascent technology ventures emboldened by Facebook's world-changing success have sought to translate the behavioral tricks that psychologist B.F. Skinner applied to the gambling kiosk to every mobile app under the sun. "When a gambler feels favored by luck, dopamine is released," Natasha Schüll, author of Addiction by Design: Machine Gambling in Las Vegas, told the Guardian in March. All Facebook managed to do was find a way to miniaturize the captivating logic of the slot machine—with no cost to the user but their time and attention.

While the human brain is tremendously plastic, that doesn't mean Facebook is savagely rewiring the human brain. Indeed, the Facebook users in the Cal State–Fullerton study "showed greater activation of their amygdala and striatum, brain regions that are involved in impulsive behavior," as Live Science's Tia Ghose reported at the time. Ghose continued: "But unlike in the brains of cocaine addicts, for instance, the Facebook users showed no quieting of the brain systems responsible for inhibition in the prefrontal cortex." Facebook isn't fundamentally rewiring the structure of the human brain, but its ubiquity has the same relative effect by kicking our rewards centers into overdrive.

As Foucault said of Bachelard a few years later, his characteristic approach was to avoid all defined hierarchies, any universal judgments: ‘He plays against his own culture with his own culture.’ He stood apart, separating himself from the mainstream, finding cracks, dissonances, minor phenomena that he could make his own. Poetry of every description was his raw material.

Indoors, in The Poetics of Space, the journey into intimacy is neatly evoked by drawers, cupboards, wardrobes and above all locks, although he warns, somewhat testily, against their use as gratuitous metaphors (and he is strongly averse to the idea of habit).

The wellbeing of the warm animal (or human) protected in its nest or cocoon or cottage from the bad weather raging outside is a primitive sense of refuge that we can all share, adult or child. The appeal of a safe haven translates into domestic architecture with such features as the accommodating Arts and Crafts inglenook, seats close by the fire, Frank Lloyd Wright’s enduring penchant for an immense fireplace buried at the core of a house, or even, a favourite 1960s touch, the conversation pit – with or without its trademark shagpile carpet.

Artificial intelligence may have cracked the code on certain tasks that typically require human smarts, but in order to learn, these algorithms need vast quantities of data that humans have produced. They hoover up that information, rummage around in search of commonalities and correlations, and then offer a classification or prediction (whether that lesion is cancerous, whether you’ll default on your loan) based on the patterns they detect. Yet they’re only as clever as the data they’re trained on, which means that our limitations—our biases, our blind spots, our inattention—become theirs as well.

The majority of AI systems used in commercial applications—the ones that mediate our access to services like jobs, credit, and loans— are proprietary, their algorithms and training data kept hidden from public view. That makes it exceptionally difficult for an individual to interrogate the decisions of a machine or to know when an algorithm, trained on historical examples checkered by human bias, is stacked against them. And forget about trying to prove that AI systems may be violating human rights legislation.

Data is essential to the operation of an AI system. And the more complicated the system—the more layers in the neural nets, to translate speech or identify faces or calculate the likelihood someone defaults on a loan—the more data must be collected.

The big divide in America is not between the coasts and the interior. It’s between strong communities and weak communities. You can find weak ones along the coast and thriving ones in Appalachia, and vice versa. It’s community, stupid — not geography.The communities that are making it share a key attribute: They’ve created diverse adaptive coalitions, where local businesses get deeply involved in the school system, translating in real time the skills being demanded by the global economy.

Show me a community that understands today’s world and is working together to thrive within it, and I’ll show you a community on the rise — coastal or interior, urban or rural.

What is wrong with America is that too many communities, rural and urban, have broken down. What is right with America is the many communities and regions that are coming together to help their citizens acquire the skills and opportunities to own their own futures. We need to share and scale these success stories.

According to a 2016 study by the nonprofit Greater New Orleans, this fledgling water workforce will grow by more than 20 percent over the next 10 years, creating more than 13,600 snazzy new titles like conservation technician, civil engineer and environmental scientist that pay an average of $69,277, well above the national average salary. “Louisiana is one of the first to turn the issue of climate change from an environmental one to an existential and economic one … through the cutting-edge jobs of the future,” claims Greater New Orleans’ executive vice president and chief operating officer Robin Barnes. Which is the city’s way of putting up a NOW HIRING billboard.

Meanwhile, troubled coastal cities around the world are taking note, says Bren Haase, head of planning for the Coastal Protection and Restoration Authority. With a playbook in place, Louisiana already boasts a 50-year, $50 billion plan to rebuild the state’s coasts, one that’s grounded in decades of data and science; it’s also being translated into several languages, including Vietnamese, Spanish and French, for other countries to reference. Flush with billions of dollars from the settlement in the catastrophic BP oil spill, the Coastal Master Plan could hold key clues for other places facing a similar fate in the future, says Haase, including flood-risk areas like New York, London, Singapore and Kiribati. Moreover, Louisiana’s coastal restoration sector is fueling high-tech projects like artificial oyster reef creation, advanced hydrologic modeling and geosynthetics, which will help shore up the state’s defenses against behemoth hurricanes and oil spills.
