Psaki added that Russians appear to be following the same playbook they used when they took control of Crimea.

The comments came hours after Ukraine was hit by a massive cyberattack warning its citizens to “expect the worst.” Ukraine’s foreign ministry spokesperson told Reuters it was too early to say who could be behind the attack, but that Russia had been behind similar strikes in the past.

Russia has massed more than 100,000 troops on its neighbor’s frontier. The Russian government has denied it has plans to attack Ukraine, but aired footage of more forces deploying to the area on Friday. Russian officials met with their U.S., European and NATO counterparts over the past week as they sought defuse tensions between the two countries.

One cannot predict the future of a marketplace by trend analysis alone, because oligopolies do not compete the same way as do firms in free markets. 

industry consolidations have created gigantic bureaucracies. Hierarchical organizations have a very different logic than smaller firms. In less consolidated industries, success and failure are largely the result of the decisions you make, so intelligence about the reality of the marketplace is critical. Life is different in gigantic organizations, where success and failure are almost impossible to attribute to individual decisions.

In large, slow-moving bureaucracies, conventional thinking and risk avoidance become paramount

, the world's economy is today driven more by policy makers than at any time in recent history. At the behest of government officials, banks have been shielded from the consequences of their market decisions, and in many cases exempt from prosecution for their potential law-breaking. Nation-state policy-makers pick the winners in industries

How can you use classical competitive analysis to examine the future of markets when the relationships between firms and government agencies are so incestuous and the choices of consumers so severely limited by industrial consolidation?

Companies still need guidance, but if rational analysis is nearly impossible, is it any wonder that executives are asking for less of it? What they are asking for is something, well, less productive.

executives today do not do well when their analysts confront them with challenging, though often relatively benign, predictions. Confusion, anger, and psychological transference are common responses to unwelcome analysis.

Of course! Romney says this as if it’s completely obvious that reducing the deficit in the short term would throw the economy back into recession, even though he and his party have been arguing the opposite case with hysterical fervor.

After World War II, its constitution and institutions were designed with the underlying goal of preventing the rise of another Nazi regime

is just one of many particular aspects of German democracy—some codified in law or in the constitution, others unwritten rules of political engagement—aimed at protecting democracy and combating extremism, particularly on the right.

“The basic idea behind [the German political system] is that certain boundaries must be drawn within democracy, that should make it impossible for an antidemocratic force to take over power,”

“Whether that is realistic is another question."

More than five million people supported the AfD in the 2017 federal elections, earning it 12.6 percent of the vote nationally and more than 90 seats in the German Bundestag. And as of October, the party is represented in all 16 of Germany’s state legislatures.

Some of the party’s most visible politicians have promoted a revisionist view of the country’s dark past, most notably Björn Höcke, who leads the “Wing,

He has called Berlin’s Holocaust Memorial, a collection of thousands of gray concrete pillars down the street from the Bundestag and the Brandenburg Gate, a “monument of shame” and once downplayed and defended a Nazi activist’s Holocaust denial. The party co-leader, Alexander Gauland has also come under fire: He referred to the Nazi era as a mere “speck of bird poop” in the country’s otherwise illustrious history and said that Germany should be proud of its World War II soldiers.

"It may be that the majority of the AfD doesn't agree with everything Mr. Höcke says. The decisive thing is that Mr. Höcke isn't marginalized and isn't isolated,”

when it comes to involvement in certain topics or committee assignments—intelligence, or the culture committees that oversee museums and memorials, for example—lawmakers have rejected or delayed AfD nominees they find offensive or inappropriate.

The AfD “triggers the kind of debate that you want to have in a live democracy, where people have to define the terms on which debate has to be had, again and again,” he told me. “It is also ... a signal that democracy wants to defend itself, no matter how difficult.”

For example, Atlas misrepresented the effectiveness of masks, suggested that lockdowns kill people and discouraged testing of asymptomatic people.

He also dismissed forecasts from the Institute for Health Metrics and Evaluation at the University of Washington School of Medicine that forecasts 399,000 coronavirus deaths in the US by February 1 under current conditions.

In October, Twitter removed a tweet from Atlas that sought to undermine the importance of wearing a face mask, because Atlas' tweet was in violation of the its Covid-19 Misleading Information Policy, a spokesman for the company told CNN. The tweet said, "Masks work? NO" followed by a series of falsehoods about the science behind the effectiveness of masks in combating the pandemic.

“The one thing I've said to him directly, and I would advise my Republican friends in Congress and supporters around the country, is just make sure that, as we go forward, certain norms, certain institutional traditions, don't get eroded, because there's a reason they're in place.”

Obama is also clearly still frustrated with how Republicans handled his Supreme Court nominee. “The fact that Mitch McConnell--the leader of the Republicans--was able to just stop a nomination almost a year before the next election and really not pay a political price for it,” Obama said. “That's a sign that the incentives for politicians in this town to be so sharply partisan have gotten so out of hand that we're weakening ourselves.”

What “disturbed me the most,” Obama said, about the intelligence finding that Russia tried to undermine the U.S. election was the response by some Republicans and, implicitly, Trump.

“In some circles, you've seen people suggest that Vladimir Putin has more credibility than the U.S. government. I think that's something new,” Obama said. “And I think it's a measure of how the partisan divide has gotten so severe that people forget we're on the same team.”

“Don't underestimate the guy,” Obama said. “Because he's going to be 45th president of the United States.”

Is this all sounding rather familiar now? Does it remind you of something?

The similarities between Gamergate and the far-right online movement, the “alt-right”, are huge, startling and in no way a coincidence

fter all, the culture war that began in games now has a senior representative in The White House. As a founder member and former executive chair of Brietbart News, Steve Bannon had a hand in creating media monster Milo Yiannopoulos, who built his fame and Twitter following by supporting and cheerleading Gamergate. This hashtag was the canary in the coalmine, and we ignored it.

Gamergate was an online movement that effectively began because a man wanted to punish his ex girlfriend. Its most notable achievement was harassing a large number of progressive figures - mostly women – to the point where they felt unsafe or considered leaving the industry

The same voices moved into other geek communities, especially comics, where Marvel and DC were criticised for progressive storylines and decisions. They moved into science fiction with the controversy over the Hugo awards. They moved into cinema with the revolting kickback against the all-female Ghostbusters reboot.

no one in the movement was willing to be associated with the abuse being carried out in its name. Prominent supporters on Twitter, in subreddits and on forums like 8Chan, developed a range of pernicious rhetorical devices and defences to distance themselves from threats to women and minorities in the industry: the targets were lying or exaggerating, they were too precious; a language of dismissal and belittlement was formed against them. Safe spaces, snowflakes, unicorns, cry bullies. Even when abuse was proven, the usual response was that people on their side were being abused too. These techniques, forged in Gamergate, have become the standard toolset of far-right voices online

In 2016, new wave conservative media outlets like Breitbart have gained trust with their audience by painting traditional news sources as snooty and aloof. In 2014, video game YouTube stars, seeking to appear in touch with online gaming communities, unscrupulously proclaimed that traditional old-media sources were corrupt. Everything we’re seeing now, had its precedent two years ago.

With 2014’s Gamergate, Breitbart seized the opportunity to harness the pre-existing ignorance and anger among disaffected young white dudes. With Trump’s movement in 2016, the outlet was effectively running his campaign: Steve Bannon took leave of his role at the company in August 2016 when he was hired as chief executive of Trump’s presidential campaign

young men converted via 2014’s Gamergate, are being more widely courted now. By leveraging distrust and resentment towards women, minorities and progressives, many of Gamergate’s most prominent voices – characters like Mike Cernovich, Adam Baldwin, and Milo Yiannopoulos – drew power and influence from its chaos

These figures gave Gamergate a new sense of direction – generalising the rhetoric: this was now a wider war between “Social Justice Warriors” (SJWs) and everyday, normal, decent people. Games were simply the tip of the iceberg – progressive values, went the argument, were destroying everything

it quickly became clear that the GamerGate movement was a mess – an undefined mission to Make Video Games Great Again via undecided means.

Using 4chan (and then the more sympathetic offshoot 8Chan) to plan their subversions and attacks made Gamergate a terribly sloppy operation, leaving a trail of evidence that made it quite clear the whole thing was purposefully, plainly nasty. But the video game industry didn’t have the spine to react, and allowed the movement to coagulate – forming a mass of spiteful disappointment that Breitbart was only more than happy to coddle

Historically, that seems to be Breitbart’s trick - strongly represent a single issue in order to earn trust, and then gradually indoctrinate to suit wider purposes. With Gamergate, they purposefully went fishing for anti-feminists. 2016’s batch of fresh converts – the white extremists – came from enticing conspiracy theories about the global neoliberal elite secretly controlling the world.

The greatest strength of Gamergate, though, was that it actually appeared to represent many left-leaning ideals: stamping out corruption in the press, pushing for better ethical practices, battling for openness.

There are similarities here with many who support Trump because of his promises to put an end to broken neo-liberalism, to “drain the swamp” of establishment corruption. Many left-leaning supporters of Gamergate sought to intellectualise their alignment with the hashtag, adopting familiar and acceptable labels of dissent – identifying as libertarian, egalitarian, humanist.

At best they unknowingly facilitated abuse, defending their own freedom of expression while those who actually needed support were threatened and attacked.

Genuine discussions over criticism, identity and censorship were paralysed and waylaid by Twitter voices obsessed with rhetorical fallacies and pedantic debating practices. While the core of these movements make people’s lives hell, the outer shell – knowingly or otherwise – protect abusers by insisting that the real problem is that you don’t want to talk, or won’t provide the ever-shifting evidence they politely require.

In 2017, the tactics used to discredit progressive game critics and developers will be used to discredit Trump and Bannon’s critics. There will be gaslighting, there will be attempts to make victims look as though they are losing their grip on reality, to the point that they gradually even start to believe it. The “post-truth” reality is not simply an accident – it is a concerted assault on the rational psyche.

The strangest aspect of Gamergate is that it consistently didn’t make any sense: people chose to align with it, and yet refused responsibility. It was constantly demanded that we debate the issues, but explanations and facts were treated with scorn. Attempts to find common ground saw the specifics of the demands being shifted: we want you to listen to us; we want you to change your ways; we want you to close your publication down. This movement that ostensibly wanted to protect free speech from cry bully SJWs simultaneously did what it could to endanger sites it disagreed with, encouraging advertisers to abandon support for media outlets that published stories critical of the hashtag. The petulance of that movement is disturbingly echoed in Trump’s own Twitter feed.

Looking back, Gamergate really only made sense in one way: as an exemplar of what Umberto Eco called “eternal fascism”, a form of extremism he believed could flourish at any point in, in any place – a fascism that would extol traditional values, rally against diversity and cultural critics, believe in the value of action above thought and encourage a distrust of intellectuals or experts – a fascism built on frustration and machismo. The requirement of this formless fascism would – above all else – be to remain in an endless state of conflict, a fight against a foe who must always be portrayed as impossibly strong and laughably weak

2016 has presented us with a world in which our reality is being wilfully manipulated. Fake news, divisive algorithms, misleading social media campaigns.

The majority of people who voted for Trump will never take responsibility for his racist, totalitarian policies, but they’ll provide useful cover and legitimacy for those who demand the very worst from the President Elect. Trump himself may have disavowed the “alt-right”, but his rhetoric has led to them feeling legitimised. As with Gamergate, the press risks being manipulated into a position where it has to tread a respectful middle ground that doesn’t really exist.

Perhaps the true lesson of Gamergate was that the media is culturally unequipped to deal with the forces actively driving these online movements. The situation was horrifying enough two years ago, it is many times more dangerous now.

During the Cold War, the Ford administration convened a Team B comprised of conservative foreign-policy thinkers to challenge the intelligence community’s estimates of Soviet nuclear capabilities. Then-CIA director and future President George H.W. Bush later concluded the group’s work lent “itself to manipulation for purposes other than estimative accuracy.”

In the early 1990s, after a rocky confirmation process during which he was accused of politicizing intelligence analysis, Director of the CIA Robert Gates implemented a series of reforms aimed at guarding against political or ideological thinking coloring intelligence analysis. Gates described politicization as “deliberately distorting analysis or judgments to favor a preferred line of thinking irrespective of evidence.”

during my tenure as an analyst with the CIA—President George W. Bush’s administration exerted unusual pressure to have the CIA support its plans to invade Iraq because of that country’s alleged ties to al-Qaeda and its weapons of mass destruction program. Both assumptions proved flawed.

An internal CIA post-mortem concluded that the CIA’s assessments of the Iraqi WMD program were a case of an effective denial-and-deception program that fed prevailing assumptions.

Intelligence analysis is more an imperfect art than it is a science: Gaps in reporting, bad sources, and circular reporting all complicate the analyst’s quest for knowledge and understanding

Politicization, however, sits on top of all of these complicating factors because it is an act of willful commission: At its most overt, it amounts to using a political position to get people to say that a clear, bright blue sky is cloudy

Speaking “truth to power” requires courage, because political partisans are all too happy to causally decry dissent as disloyalty.

What is the cost of politicization? As of 2013, it was estimated that the American invasion of Iraq in 2003 cost an estimated $1.7 trillion, and saw over 4,000 Americans killed in action and over 30,000 wounded in action. Those numbers don’t include the families of the fallen; the innocent Iraqis killed or wounded during the conflict; or the insurgency that evolved into the extremist threat that we now know as ISIS.

The irony is that President Trump is a vocal critic of his predecessors’ decisions to invade, occupy, and ultimately withdraw from Iraq. In the run-up to that war, the Department of Defense formed an Office of Special Plans, conceived by Deputy Secretary of Defense Paul Wolfowitz, which as Seymour Hersh argued in The New Yorker, “was created in order to find evidence of what Wolfowitz and his boss, Defense Secretary Donald Rumsfeld, believed to be true” about Iraq the threat it posed to the world

Intel, founded by Gordon Moore and Robert Noyce, both physicists, began by building memory chips that were twice as fast as old ones. Sun Microsystems introduced a new kind of modular computer system, built by one of its founders, Andy Bechtolsheim. Their “big ideas” were expressed in physical products and grew out of their own technical expertise. In that light, Meraki, which came from Biswas’s work at M.I.T., can be seen as having its origins in the old guard. And it followed what was for decades the highway that connected academia to industry: Grad students researched technology, powerful advisers brokered deals, students dropped out to parlay their technologies into proprietary solutions, everyone reaped the profits. That implicit guarantee of academia’s place in entrepreneurship has since disappeared. Graduate students still drop out, but to start bike-sharing apps and become data scientists. That is, if they even make it to graduate school. The success of self-educated savants like Sean Parker, who founded Napster and became Facebook’s first president with no college education to speak of, set the template. Enstitute, a two-year apprenticeship, embeds high-school graduates in plum tech positions. Thiel Fellowships, financed by the PayPal co-founder and Facebook investor Peter Thiel, give $100,000 to people under 20 to forgo college and work on projects of their choosing.

Much of this precocity — or dilettantism, depending on your point of view — has been enabled by web technologies, by easy-to-use programming frameworks like Ruby on Rails and Node.js and by the explosion of application programming interfaces (A.P.I.s) that supply off-the-shelf solutions to entrepreneurs who used to have to write all their own code for features like a login system or an embedded map. Now anyone can do it, thanks to the Facebook login A.P.I. or the Google Maps A.P.I.

One of the more enterprising examples of these kinds of interfaces is the start-up Stripe, which sells A.P.I.s that enable businesses to process online payments. When Meraki first looked into taking credit cards online, according to Biswas, it was a monthslong project fraught with decisions about security and cryptography. “Now, with Stripe, it takes five minutes,” he said. “When you combine that with the ability to get a server in five minutes, with Rails and Twitter Bootstrap, you see that it has become infinitely easier for four people to get a start-up off the ground.”

The sense that it is no longer necessary to have particularly deep domain knowledge before founding your own start-up is real; that and the willingness of venture capitalists to finance Mark Zuckerberg look-alikes are changing the landscape of tech products. There are more platforms, more websites, more pat solutions to serious problems

There’s a glass-half-full way of looking at this, of course: Tech hasn’t been pedestrianized — it’s been democratized. The doors to start-up-dom have been thrown wide open. At Harvard, enrollment in the introductory computer-science course, CS50, has soared

many of the hottest web start-ups are not novel, at least not in the sense that Apple’s Macintosh or Intel’s 4004 microprocessor were. The arc of tech parallels the arc from manufacturing to services. The Macintosh and the microprocessor were manufactured products. Some of the most celebrated innovations in technology have been manufactured products — the router, the graphics card, the floppy disk

One of Stripe’s founders rowed five seat in the boat I coxed freshman year in college; the other is his older brother. Among the employee profiles posted on its website, I count three of my former teaching fellows, a hiking leader, two crushes. Silicon Valley is an order of magnitude bigger than it was 30 years ago, but still, the start-up world is intimate and clubby, with top talent marshaled at elite universities and behemoths like Facebook and Google.

A few weeks ago, a programmer friend and I were talking about unhappiness, in particular the kind of unhappiness that arises when you are 21 and lavishly educated with the world at your feet. In the valley, it’s generally brought on by one of two causes: coming to the realization either that your start-up is completely trivial or that there are people your own age so knowledgeable and skilled that you may never catch up.

The latter source of frustration is the phenomenon of “the 10X engineer,” an engineer who is 10 times more productive than average. It’s a term that in its cockiness captures much of what’s good, bad and impossible about the valley. At the start-ups I visit, Friday afternoons devolve into bouts of boozing and Nerf-gun wars. Signing bonuses at Facebook are rumored to reach the six digits. In a landscape where a product may morph several times over the course of a funding round, talent — and the ability to attract it — has become one of the few stable metrics.

there is a surprising amount of angst in Silicon Valley. Which is probably inevitable when you put thousands of ambitious, talented young people together and tell them they’re god’s gift to technology. It’s the angst of an early hire at a start-up that only he realizes is failing; the angst of a founder who raises $5 million for his company and then finds out an acquaintance from college raised $10 million; the angst of someone who makes $100,000 at 22 but is still afraid that he may not be able to afford a house like the one he grew up in.

San Francisco, which is steadily stealing the South Bay’s thunder. (“Sometime in the last two years, the epicenter of consumer technology in Silicon Valley has moved from University Ave. to SoMa,” Terrence Rohan, a venture capitalist at Index Ventures, told me

Both the geographic shift north and the increasingly short product cycles are things Jim attributes to the rise of Amazon Web Services (A.W.S.), a collection of servers owned and managed by Amazon that hosts data for nearly every start-up in the latest web ecosystem.Continue reading the main story

now, every start-up is A.W.S. only, so there are no servers to kick, no fabs to be near. You can work anywhere. The idea that all you need is your laptop and Wi-Fi, and you can be doing anything — that’s an A.W.S.-driven invention.”

This same freedom from a physical location or, for that matter, physical products has led to new work structures. There are no longer hectic six-week stretches that culminate in a release day followed by a lull. Every day is release day. You roll out new code continuously, and it’s this cycle that enables companies like Facebook, as its motto goes, to “move fast and break things.”

Part of the answer, I think, lies in the excitement I’ve been hinting at. Another part is prestige. Smart kids want to work for a sexting app because other smart kids want to work for the same sexting app. “Highly concentrated pools of top talent are one of the rarest things you can find,” Biswas told me, “and I think people are really attracted to those environments.

These days, a new college graduate arriving in the valley is merely stepping into his existing network. He will have friends from summer internships, friends from school, friends from the ever-increasing collection of incubators and fellowships.

As tech valuations rise to truly crazy levels, the ramifications, financial and otherwise, of a job at a pre-I.P.O. company like Dropbox or even post-I.P.O. companies like Twitter are frequently life-changing. Getting these job offers depends almost exclusively on the candidate’s performance in a series of technical interviews, where you are asked, in front of frowning hiring managers, to whip up correct and efficient code.

Moreover, a majority of questions seem to be pulled from undergraduate algorithms and data-structures textbooks, which older engineers may have not laid eyes on for years.

proportionality requires that the use of lethal force be justified by the imminence and danger of the threat, for which there is no evidence in the clips and likely only useless CIA intel to back it up.

Putative war crimes, repellant videos, porn mentality, the counterproductive creation of generations of terrorists: On grounds both moral and practical, the drone attacks must cease.

Using BetterWorks software, workers set goals, like “Sign 10 new customers by May,” and enter them into an internal system that can be viewed by other employees — it looks almost identical to the dashboard function used by Fitbit fitness trackers. Co-workers can give each other encouragement (“cheers”) or shaming (“nudges”). A worker’s profile shows a digital tree that grows with accomplishments and shrivels with poor productivity

One of the main ways people become more productive on the job is by using their supposed downtime to do even more work. Many drivers did things like loading, unloading and inspecting their trucks during federally required breaks, Ms. Levy said

“If you distract workers with the idea that they are playing the game, they don’t challenge the rules of the game,

Companies like BetterWorks — Workday, Workboard or SuccessFactors also make goal-setting software — are importing similar concepts to office jobs where performance has historically been more subjective.

Culture Amp’s product is essentially a set of continuous, anonymous surveys that lets companies know how their workers are feeling and rates them against other companies in the same industry.

For years, observers have wondered if Amazon’s shopping business — you know, its main business — could ever really work. Investors gave Mr. Bezos enormous leeway to spend billions building out a distribution-center infrastructure, but it remained a semi-open question if the scale and pace of investments would ever pay off. Could this company ever make a whole lot of money selling so much for so little?

Amazon’s retail operations had reached a “critical scale” or an “inflection point.” They meant that Amazon’s enormous investments in infrastructure and logistics have begun to pay off. The company keeps capturing a larger slice of American and even international purchases. It keeps attracting more users to its Prime fast-shipping subscription program, and, albeit slowly, it is beginning to scratch out higher profits from shoppers.

Now that Amazon has hit this point, it’s difficult to see how any other retailer could catch up anytime soon. I recently asked a couple of Silicon Valley venture capitalists who have previously made huge investments in e-commerce whether they were keen to spend any more in the sector. They weren’t, citing Amazon.

“The truth is they’re building a really insurmountable infrastructure that I don’t see how others can really deal with,”

Amazon also faces a wider set of competitive threats internationally. Although it has reported increasingly brisk sales in India, the company has had a difficult time breaking into the lucrative Chinese market, where Alibaba dominates the shopping scene

Walmart, which on Tuesday published earnings that came in slightly above analysts’ expectations, is also spending billions to slow Amazon’s roll. But Walmart said that in its latest quarter, e-commerce sales had grown only 10 percent from a year ago. Amazon’s retail sales rose 20 percent during the same period.

What has been key to this rise, and missing from many of his competitors’ efforts, is patience. In a very old-fashioned manner, one that is far out of step with a corporate world in which milestones are measured every three months, Amazon has been willing to build its empire methodically and at great cost over almost two decades, despite skepticism from many sectors of the business world.

Amazon has built more than 100 warehouses from which to package and ship goods, and it hasn’t really slowed its pace in establishing more. Because the warehouses speed up Amazon’s shipping, encouraging more shopping, the costs of these centers is becoming an ever-smaller fraction of Amazon’s operations.

Amazon’s investments in Prime, the $99-a-year service that offers free two-day shipping, are also paying off. Last year Mr. Bezos told me that people were increasingly signing up for Prime for the company’s media offerings

Mr. Schachter, of Macquarie Securities, estimates that there will be at least 40 million Prime subscribers by the end of this year, and perhaps as many as 60 million, up from an estimated 30 million at the beginning of 2015

he predicted that by 2020, 50 percent of American households will have joined Prime, “and that’s very conservative,” he said.

its operating margin on the North American retail business was 3.5 percent, while Amazon Web Services’s margin was 25 percent.

“retail gross profit dollars per customer” — a fancy way of measuring how much Amazon makes from each shopper — has accelerated in each of the last four quarters, in part because of Prime. Amazon keeps winning “a larger share of customers’ wallets,” the firm said, eventually “leading to a period of sustained, rising profitability.”

“The thing about retail is, the consumer has near-perfect information,” said Paul Vogel, an analyst at Barclays. “So what’s the differentiator at this point? It’s selection. It’s service. It’s convenience. It’s how easy it is to use their interface. And Amazon’s got all this stuff already. How do you compete with that? I don’t know, man. It’s really hard.

economists are reassessing their belief that technological progress lifts all boats, and are beginning to worry about the new configuration of work.

“We automate the pieces that can be automated,” said Paul Hart, a senior vice president running the radio-frequency power business at NXP’s plant in Chandler. “The work force grows but we need A.I. and automation to increase the throughput.”

“The view that we should not worry about any of these things and follow technology to wherever it will go is insane,”

But the industry doesn’t generate that many jobs

Because it pushes workers to the less productive parts of the economy, automation also helps explain one of the economy’s thorniest paradoxes: Despite the spread of information technology, robots and artificial intelligence breakthroughs, overall productivity growth remains sluggish.

Axon, which makes the Taser as well as body cameras used by police forces, is also automating whatever it can. Today, robots make four times as many Taser cartridges as 80 workers once did less than 10 years ago

The same is true across the high-tech landscape. Aircraft manufacturing employed 4,234 people in 2017, compared to 4,028 in 2010. Computer systems design services employed 11,000 people in 2017, up from 7,000 in 2010.

To find the bulk of jobs in Phoenix, you have to look on the other side of the economy: where productivity is low. Building services, like janitors and gardeners, employed nearly 35,000 people in the area in 2017, and health care and social services accounted for 254,000 workers. Restaurants and other eateries employed 136,000 workers, 24,000 more than at the trough of the recession in 2010. They made less than $450 a week.

While Banner invests heavily in technology, the machines do not generally reduce demand for workers. “There are not huge opportunities to increase productivity, but technology has a significant impact on quality,” said Banner’s chief operating officer, Becky Kuhn

The 58 most productive industries in Phoenix — where productivity ranges from $210,000 to $30 million per worker, according to Mr. Muro’s and Mr. Whiton’s analysis — employed only 162,000 people in 2017, 14,000 more than in 2010

Employment in the 58 industries with the lowest productivity, where it tops out at $65,000 per worker, grew 10 times as much over the period, to 673,000.

The same is true across the national economy. Jobs grow in health care, social assistance, accommodation, food services, building administration and waste services

On the other end of the spectrum, the employment footprint of highly productive industries, like finance, manufacturing, information services and wholesale trade, has shrunk over the last 30 years

“In the standard economic canon, the proposition that you can increase productivity and harm labor is bunkum,” Mr. Acemoglu said

By reducing prices and improving quality, technology was expected to raise demand, which would require more jobs. What’s more, economists thought, more productive workers would have higher incomes. This would create demand for new, unheard-of things that somebody would have to make

To prove their case, economists pointed confidently to one of the greatest technological leaps of the last few hundred years, when the rural economy gave way to the industrial era.

In 1900, agriculture employed 12 million Americans. By 2014, tractors, combines and other equipment had flushed 10 million people out of the sector. But as farm labor declined, the industrial economy added jobs even faster. What happened? As the new farm machines boosted food production and made produce cheaper, demand for agricultural products grew. And farmers used their higher incomes to purchase newfangled industrial goods.

The new industries were highly productive and also subject to furious technological advancement. Weavers lost their jobs to automated looms; secretaries lost their jobs to Microsoft Windows. But each new spin of the technological wheel, from plastic toys to televisions to computers, yielded higher incomes for workers and more sophisticated products and services for them to buy.

In a new study, David Autor of the Massachusetts Institute of Technology and Anna Salomons of Utrecht University found that over the last 40 years, jobs have fallen in every single industry that introduced technologies to enhance productivity.

The only reason employment didn’t fall across the entire economy is that other industries, with less productivity growth, picked up the slack. “The challenge is not the quantity of jobs,” they wrote. “The challenge is the quality of jobs available to low- and medium-skill workers.”

the economy today resembles what would have happened if farmers had spent their extra income from the use of tractors and combines on domestic servants. Productivity in domestic work doesn’t grow quickly. As more and more workers were bumped out of agriculture into servitude, productivity growth across the economy would have stagnated.

The growing awareness of robots’ impact on the working class raises anew a very old question: Could automation go too far? Mr. Acemoglu and Pascual Restrepo of Boston University argue that businesses are not even reaping large rewards for the money they are spending to replace their workers with machines.

the cost of automation to workers and society could be substantial. “It may well be that,” Mr. Summers said, “some categories of labor will not be able to earn a subsistence income.” And this could exacerbate social ills, from workers dropping out of jobs and getting hooked on painkillers, to mass incarceration and families falling apart.

Silicon Valley’s dream of an economy without workers may be implausible. But an economy where most people toil exclusively in the lowliest of jobs might be little better.
