“What companies are looking for,” says Mary Jo King, the president of the National Résumé Writers’ Association, “is someone who can be all, do all, and pivot on a dime to solve any problem.”

The phenomenon is sped by automation, which usurps routine tasks, leaving employees to handle the nonroutine and unanticipated—and the continued advance of which throws the skills employers value into flux

Or, for that matter, on the relevance of the question What do you want to be when you grow up?

By 2020, a 2016 World Economic Forum report predicted, “more than one-third of the desired core skill sets of most occupations” will not have been seen as crucial to the job when the report was published

I asked John Sullivan, a prominent Silicon Valley talent adviser, why should anyone take the time to master anything at all? “You shouldn’t!” he replied.

Minimal manning—and the evolution of the economy more generally—requires a different kind of worker, with not only different acquired skills but different inherent abilities

It has implications for the nature and utility of a college education, for the path of careers, for inequality and employability—even for the generational divide.

Then, in 2001, Donald Rumsfeld arrived at the Pentagon. The new secretary of defense carried with him a briefcase full of ideas from the corporate world: downsizing, reengineering, “transformational” technologies. Almost immediately, what had been an experimental concept became an article of faith

But once cadets got into actual command environments, which tend to be fluid and full of surprises, a different picture emerged. “Psychological hardiness”—a construct that includes, among other things, a willingness to explore “multiple possible response alternatives,” a tendency to “see all experience as interesting and meaningful,” and a strong sense of self-confidence—was a better predictor of leadership ability in officers after three years in the field.

Because there really is no such thing as multitasking—just a rapid switching of attention—I began to feel overstrained, put upon, and finally irked by the impossible set of concurrent demands. Shouldn’t someone be giving me a hand here? This, Hambrick explained, meant I was hitting the limits of working memory—basically, raw processing power—which is an important aspect of “fluid intelligence” and peaks in your early 20s. This is distinct from “crystallized intelligence”—the accumulated facts and know-how on your hard drive—which peaks in your 50

Others noticed the change but continued to devote equal attention to all four tasks. Their scores fell. This group, Hambrick found, was high in “conscientiousness”—a trait that’s normally an overwhelming predictor of positive job performance. We like conscientious people because they can be trusted to show up early, double-check the math, fill the gap in the presentation, and return your car gassed up even though the tank was nowhere near empty to begin with. What struck Hambrick as counterintuitive and interesting was that conscientiousness here seemed to correlate with poor performance.

he discovered another correlation in his test: The people who did best tended to score high on “openness to new experience”—a personality trait that is normally not a major job-performance predictor and that, in certain contexts, roughly translates to “distractibility.”

To borrow the management expert Peter Drucker’s formulation, people with this trait are less focused on doing things right, and more likely to wonder whether they’re doing the right things.

High in fluid intelligence, low in experience, not terribly conscientious, open to potential distraction—this is not the classic profile of a winning job candidate. But what if it is the profile of the winning job candidate of the future?

One concerns “grit”—a mind-set, much vaunted these days in educational and professional circles, that allows people to commit tenaciously to doing one thing well

These ideas are inherently appealing; they suggest that dedication can be more important than raw talent, that the dogged and conscientious will be rewarded in the end.

he studied West Point students and graduates.

Traditional measures such as SAT scores and high-school class rank “predicted leader performance in the stable, highly regulated environment of West Point” itself.

It would be supremely ironic if the advance of the knowledge economy had the effect of devaluing knowledge. But that’s what I heard, recurrentl

“Fluid, learning-intensive environments are going to require different traits than classical business environments,” I was told by Frida Polli, a co-founder of an AI-powered hiring platform called Pymetrics. “And they’re going to be things like ability to learn quickly from mistakes, use of trial and error, and comfort with ambiguity.”

“We’re starting to see a big shift,” says Guy Halfteck, a people-analytics expert. “Employers are looking less at what you know and more and more at your hidden potential” to learn new things

advice to employers? Stop hiring people based on their work experience. Because in these environments, expertise can become an obstacle.

“The Curse of Expertise.” The more we invest in building and embellishing a system of knowledge, they found, the more averse we become to unbuilding it.

All too often experts, like the mechanic in LePine’s garage, fail to inspect their knowledge structure for signs of decay. “It just didn’t occur to him,” LePine said, “that he was repeating the same mistake over and over.

The devaluation of expertise opens up ample room for different sorts of mistakes—and sometimes creates a kind of helplessness.

Aboard littoral combat ships, the crew lacks the expertise to carry out some important tasks, and instead has to rely on civilian help

Meanwhile, the modular “plug and fight” configuration was not panning out as hoped. Converting a ship from sub-hunter to minesweeper or minesweeper to surface combatant, it turned out, was a logistical nightmare

So in 2016 the concept of interchangeability was scuttled for a “one ship, one mission” approach, in which the extra 20-plus sailors became permanent crew members

“As equipment breaks, [sailors] are required to fix it without any training,” a Defense Department Test and Evaluation employee told Congress. “Those are not my words. Those are the words of the sailors who were doing the best they could to try to accomplish the missions we gave them in testing.”

These results were, perhaps, predictable given the Navy’s initial, full-throttle approach to minimal manning—and are an object lesson on the dangers of embracing any radical concept without thinking hard enough about the downsides

a world in which mental agility and raw cognitive speed eclipse hard-won expertise is a world of greater exclusion: of older workers, slower learners, and the less socially adept.

if you keep going down this road, you end up with one really expensive ship with just a few people on it who are geniuses … That’s not a future we want to see, because you need a large enough crew to conduct multiple tasks in combat.

hat does all this mean for those of us in the workforce, and those of us planning to enter it? It would be wrong to say that the 10,000-hours-of-deliberate-practice idea doesn’t hold up at all. In some situations, it clearly does

A spinal surgery will not be performed by a brilliant dermatologist. A criminal-defense team will not be headed by a tax attorney. And in tech, the demand for specialized skills will continue to reward expertise handsomely.

But in many fields, the path to success isn’t so clear. The rules keep changing, which means that highly focused practice has a much lower return

In uncertain environments, Hambrick told me, “specialization is no longer the coin of the realm.”

It leaves us with lifelong learning,

I found myself the target of career suggestions. “You need to be a video guy, an audio guy!” the Silicon Valley talent adviser John Sullivan told me, alluding to the demise of print media

I found the prospect of starting over just plain exhausting. Building a professional identity takes a lot of resources—money, time, energy. After it’s built, we expect to reap gains from our investment, and—let’s be honest—even do a bit of coasting. Are we equipped to continually return to apprentice mode? Will this burn us out?

Everybody I met on the Giffords seemed to share that mentality. They regarded every minute on board—even during a routine transit back to port in San Diego Harbor—as a chance to learn something new.

Imbued with their own neurons, octopus arms can act semi-autonomously, gathering and exchanging information without routing it through the main brain.

It’s long been unclear, for instance, how the animals, just by probing their surroundings with their limbs, can distinguish something like a crab from a less edible object.

exposed to octopus ink, which is sometimes released as a “warning signal,” Dr. van Giesen said. “Maybe there is some kind of filtering of information that is important for the animal in specific situations,” like when danger is afoot, she said.

But they found that some of the cells in the animal’s suckers would shut down when

Humans, who tend to be very visual creatures, probably can’t fully appreciate the sensory nuances of a taste-sensitive arm

“Sometimes we assume in neuroscience or animal behavior, there’s only one way of doing it

But then again, most people could probably do without the metallic tang of keys every time they rummage in their pockets — or the funk that would inevitably dissuade every new parent from changing a diaper.

Each type of sensor responds to a distinct chemical cue, giving the animals an extraordinarily refined palate that can inform how their agile arms react, jettisoning an object as useless or dangerous, or nabbing it for a snack.

The cells of octopus suckers are decorated with a mixture of tiny detector proteins. Each type of sensor responds to a distinct chemical cue, giving the animals an extraordinarily refined palate that can inform how their agile arms react, jettisoning an object as useless or dangerous, or nabbing it for a snack.

That arm has all the cellular machinery to taste your tongue right back.

(Even after amputation, these adept appendages can still snatch hungrily at morsels of food.)

Octopuses certainly know how to put that processing power to good use.

By mixing and matching these proteins, cells could develop their own unique tasting profiles, allowing the octopus’s suckers to discern flavors in fine gradations, then shoot the sensation to other parts of the nervous system.

Underwater, some chemicals can travel far from their source, making it possible for some creatures to catch a whiff of their prey from afar. But for chemicals that don’t move through the ocean easily, a touch-taste strategy is handy, Dr. Bellono said.

courage. The obvious form of intellectual courage is the willingness to hold unpopular views. But the subtler form is knowing how much risk to take in jumping to conclusions.

Intellectual courage is self-regulation, Roberts and Wood argue, knowing when to be daring and when to be cautious. The philosopher Thomas Kuhn pointed out that scientists often simply ignore facts that don’t fit with their existing paradigms, but an intellectually courageous person is willing to look at things that are surprisingly hard to look at.

The median point between flaccidity and rigidity is the virtue of firmness. The firm believer can build a steady worldview on solid timbers but still delight in new information. She can gracefully adjust the strength of her conviction to the strength of the evidence. Firmness is a quality of mental agility.

humility, which is not letting your own desire for status get in the way of accuracy. The humble person fights against vanity and self-importance.

wisdom isn’t a body of information. It’s the moral quality of knowing how to handle your own limitations.

autonomy

Autonomy is the median of knowing when to bow to authority and when not to, when to follow a role model and when not to, when to adhere to tradition and when not to.

generosity. This virtue starts with the willingness to share knowledge and give others credit. But it also means hearing others as they would like to be heard, looking for what each person has to teach and not looking to triumphantly pounce upon their errors.

thinking well means pushing against the grain of our nature — against vanity, against laziness, against the desire for certainty, against the desire to avoid painful truths. Good thinking isn’t just adopting the right technique. It’s a moral enterprise and requires good character, the ability to go against our lesser impulses for the sake of our higher ones.

The humble researcher doesn’t become arrogant toward his subject, assuming he has mastered it. Such a person is open to learning from anyone at any stage in life.

Warren Buffett made a similar point in his own sphere, “Investing is not a game where the guy with the 160 I.Q. beats the guy with the 130 I.Q. Once you have ordinary intelligence, what you need is the temperament to control the urges that get other people into trouble.”

Good piece. I only wish David had written more about all the forces that work _against_ the virtues he describes. The innumerable examples of corporate suppression/spin of "inconvenient" truths (i.e, GM, Toyota, et al); the virtual acceptance that lying is a legitimate tactic in political campaigns; our preoccupation with celebrity, appearances, and "looking good" in every imaginable transaction; make the quiet virtues that DB describes even more heroic than he suggests.

With digital tools and data science, demand for energy can now be sculpted locally to match available resources, reducing the number of power plants that utilities need to keep in reserve.

The key is giving consumers the ability to separate flexible energy uses—say, operating a Jacuzzi—from essential needs, which can now be done with phone apps for smart appliances and service panels.

Meanwhile, connections between groups of customers can be opened and closed as needed with modern, communicating circuit switchgear.

The good news is that record amounts of batteries are being installed in U.S. homes and on the electric grid, despite supply-chain bottlenecks.

The bad news is that current battery technology only offers a few hours of storage. What’s needed are more-powerful battery systems that can extend the length or scale of storing, which could be even more enabling to sun and wind power.

Two such solutions are on the horizon. Stationary metal-air batteries, such as iron-air batteries, don’t hold as much energy per kilogram as lithium-ion batteries so it takes a larger, heavier battery to do the job. But they are cheaper, iron is a plentiful metal, and the batteries, whose chemistry works via interaction of the metal with air, can be sized and installed to store and discharge a large level of electricity over days or weeks.

improved large iron-air batteries are poised to become a great new backup for renewable energy within the next couple of years to address those times of year when drops in renewable energy production can last for days and not hours.

For households, a battery configuration called a virtual power plant also holds huge potential to extend the use of renewables. These systems allow a local utility or electricity distributor to collect excess energy stored in multiple households’ battery systems and feed it back to the grid when there is a surge in demand or generation shortfall.

Electrification is a good choice for smaller vessels on short voyages, like the world’s largest all-electric ferry launched in Norway in 2021. It isn’t yet a viable option for ships on transoceanic voyages because batteries are still too large and heavy, though innovative approaches for battery swapping are being explored.

Greener Shipping

For longer voyages, e-ammonia, a hydrogen-derived fuel made with renewable energy, has been identified as a prime candidate, although work is needed to ensure safety. Ammonia has a higher energy density than some other options, making it a more economical option for powering large ships across oceans.

Among ammonia projects in the works, MAN Energy Solutions is developing engines that can run on conventional fossil fuel or ammonia, a coalition of Nordic partners is designing the world’s first ammonia-powered vessel, and Singapore is evaluating how to bunker the fuel.

Some EV makers such as Tesla are now embracing an older, less-expensive battery technology known as lithium-iron-phosphate, or LFP, used originally in scooters and small EVs in China

. It draws entirely on cheap and abundant minerals and is less flammable. The power density of LFP is less than NMC, but that disadvantage can be overcome by advances in vehicle design.

One approach being tested eliminates the outer packaging of the batteries altogether and directly installs cells, packed in layers, into a cavity in the EV’s body chassis.

Eventually, solid-state batteries—with a solid electrolyte made from common minerals like glass or ceramics—could become a key EV battery technology.

The solid electrolyte is more chemically stable, lighter, recharges faster and has many more lifetime recharging cycles than lithium-ion batteries, which depend on heavy liquid electrolytes.

these innovations are good news for those hoping to speed up EV adoption. They also suggest that batteries, far from becoming a standardized commodity, are going to be customized as auto makers create their own vehicle designs and battery makers develop proprietary platforms.
