As a young State Department policy planner in the 2000s, she was a lonely voice in Washington raising the alarm about the rise of China. She pushed for tariffs and against trade agreements before it was cool, and was an author of a book called “War by Other Means” about how blind faith in free markets put the United States at a geopolitical disadvantage. For years, she felt like an oddball in Washington, where both parties were still in thrall to neoliberalism.

The Hewlett Foundation hired her as the head of an initiative that has given away $140 million so far to people who are devising a new economic philosophy. Then she served a stint in the White House. Today, she’s an intellectual leader of a growing, bipartisan consensus

She fell in love with economics and studied it at Wake Forest. After she joined a student delegation to a NATO summit in Prague in 2002, a faculty adviser on that trip offered her a job in Washington working at the National Intelligence Council. In those early years, she believed what everyone else in Washington believed about the economy — that governments ought not meddle with it.

if Mr. Trump correctly identified a problem — “China is eating our lunch” — he did not solve it, beyond putting tariffs on Chinese products. His tax cut for the rich hurt rather than helped matters.

It’s the Biden administration that came in with a plan to build an economy that was good for workers, not just shareholders, using some strategies Ms. Harris had been talking about for years.

The thinking behind it goes like this: Unquestioning belief in the free market created a globalism that funneled money to the 1 percent, which has used its wealth to amass political power at the expense of everyone else. It produced free trade agreements that sent too many U.S. factories to China and rescue plans after the 2008 financial crisis that bailed out Wall Street instead of Main Street.

It was her job to track China’s use of subsidies, industrial espionage and currency manipulation to fuel its rise as a manufacturing powerhouse. Ms. Harris argued that tariffs on China were a necessary defense. Nobody agreed. “I was kind of just banging my head against this wall,” she told me. “The wall was a foreign policy establishment that saw markets as sacrosanct.”

Barack Obama campaigned on a pledge to renegotiate NAFTA, but he struck up a new trade deal instead — the Trans-Pacific Partnership. Ms. Harris argued against it. “We didn’t have the foggiest idea” of what it would do to our economy, she told me. Nobody listened.

it sent Democrats back to the intellectual drawing board. Larry Kramer, then the president of the Hewlett Foundation, recruited her in 2018 to promote alternatives to ideas that had guided U.S. policy for decades. He hoped she could do for free-market skepticism what Milton Friedman and his allies had done for free-market fundamentalism, which became policy under the Reagan administration and eventually was embraced by both parties as truth.

She has since rejoined the Hewlett Foundation, where she funds people who are proposing new solutions to economic problems. One grantee, the conservative think tank American Compass, promotes the idea of a domestic development bank to fund infrastructure — an idea with bipartisan appeal.

But the work that Ms. Harris and others in the Biden administration have done is unfinished, and poorly understood. The terms “Bidenomics” and “Build Back Better” don’t seem to resonate

Ms. Harris acknowledges that these ideas haven’t yet taken hold in the broader electorate, and that high interest rates overshadow the progress that’s been made. It’s too early for voters to feel it, she told me: “The investments Biden has pushed through aren’t going to be felt in a month, a year, two years.”

she celebrates the fact that leaders across the political spectrum are embracing the idea that Americans need to “get back to building things in this country.” This election has no candidates blindly promoting the free market. The last one didn’t either. In the battle of ideas, she has already won.

“Over 80 technical papers published since January 2022,” LeCun responded. “What about you?”

To which Musk posted: “That’s nothing, you’re going soft. Try harder!

At stake are the hearts and minds of AI experts—academic and otherwise—needed to usher in the technology

“Join xAI,” LeCun wrote, “if you can stand a boss who:– claims that what you are working on will be solved next year (no pressure).– claims that what you are working on will kill everyone and must be stopped or paused (yay, vacation for 6 months!).– claims to want a ‘maximally rigorous pursuit of the truth’ but spews crazy-ass conspiracy theories on his own social platform.”

Some read Musk’s “science” dig as dismissing the role research has played for a generation of AI experts. For years, the Metas and Googles of the world have hired the top minds in AI from universities, indulging their desires to keep a foot in both worlds by allowing them to release their research publicly, while also trying to deploy products. 

For an academic such as LeCun, published research, whether peer-reviewed or not, allowed ideas to flourish and reputations to be built, which in turn helped build stars in the system.

LeCun has been at Meta since 2013 while serving as an NYU professor since 2003. His tweets suggest he subscribes to the philosophy that one’s work needs to be published—put through the rigors of being shown to be correct and reproducible—to really be considered science. 

“If you do research and don’t publish, it’s not Science,” he posted in a lengthy tweet Tuesday rebutting Musk. “If you never published your research but somehow developed it into a product, you might die rich,” he concluded. “But you’ll still be a bit bitter and largely forgotten.” 

After pushback, he later clarified in another post: “What I *AM* saying is that science progresses through the collision of ideas, verification, analysis, reproduction, and improvements. If you don’t publish your research *in some way* your research will likely have no impact.”

The spat inspired debate throughout the scientific community. “What is science?” Nature, a scientific journal, asked in a headline about the dust-up.

Others, such as Palmer Luckey, a former Facebook executive and founder of Anduril Industries, a defense startup, took issue with LeCun’s definition of science. “The extreme arrogance and elitism is what people have a problem with,” he tweeted.

For Musk, who prides himself on his physics-based viewpoint and likes to tout how he once aspired to work at a particle accelerator in pursuit of the universe’s big questions, LeCun’s definition of science might sound too ivory-tower. 

Musk has blamed universities for helping promote what he sees as overly liberal thinking and other symptoms of what he calls the Woke Mind Virus. 

Over the years, an appeal of working for Musk has been the impression that his companies move quickly, filled with engineers attracted to tackling hard problems and seeing their ideas put into practice.

“I’ve teamed up with Elon to see if we can actually apply these new technologies to really make a dent in our understanding of the universe,” Igor Babuschkin, an AI expert who worked at OpenAI and Google’s DeepMind, said last year as part of announcing xAI’s mission. 

The creation of xAI quickly sent ripples through the AI labor market, with one rival complaining it was hard to compete for potential candidates attracted to Musk and his reputation for creating value

that was before xAI’s latest round raised billions of dollars, putting its valuation at $24 billion, kicking off a new recruiting drive. 

It was already a seller’s market for AI talent, with estimates that there might be only a couple hundred people out there qualified to deal with certain pressing challenges in the industry and that top candidates can easily earn compensation packages worth $1 million or more

Since the launch, Musk has been quick to criticize competitors for what he perceived as liberal biases in rival AI chatbots. His pitch of xAI being the anti-woke bastion seems to have worked to attract some like-minded engineers.

As for Musk’s final response to LeCun’s defense of research, he posted a meme featuring Pepé Le Pew that read: “my honest reaction.”

great gaming experiences speak to our inner desire for mastery, autonomy and purpose, Mr. Zichermann noted. The same can be said of travel. “Why do we travel?” he said. “It’s all about creating memories and discovering ourselves. Gamification is perfectly aligned with that.”

Gamification can engage people simply by making travel more playful and social, like Virgin America’s new seat-to-seat delivery feature that encourages fliers to “get lucky” by sending one another cocktails and messages through the entertainment system touchscreens on seatbacks

Even acquiring travel skills has become a game with language-learning Web sites like Duolingo and MindSnacks.

Despite gamification’s popularity, there are many poorly designed experiences. In fact, the technology research company Gartner is predicting that by next year 80 percent of gamification projects will fail to meet business objectives. When done right, however, gamification can garner brand loyalty while also helping travelers interact, learn, share opinions and explore the world.

companies that specialize in gamification say they are trying to design experiences that are emotional, that delight or surprise, unlike early loyalty programs

new research by the Harvard political scientist Robert D. Putnam and his colleagues shows that the rich-poor gaps in student participation in sports, extracurricular activities, volunteer work and church attendance have grown sharply as well.

average test scores on the National Assessment of Educational Progress, the so-called Nation’s Report Card, have been rising — substantially in math and very slowly in reading — since the 1970s.

The most potent development over the past three decades is that the test scores of children from high-income families have increased very rapidly.

the rich now outperform the middle class by as much as the middle class outperform the poor. Just as the incomes of the affluent have grown much more rapidly than those of the middle class over the last few decades, so, too, have most of the gains in educational success accrued to the children of the rich.

For the past few years, alongside other scholars, I have been digging into historical data to understand

It’s not just that the rich have more money than they used to, it’s that they are using it differently. This is where things get really interesting.

The widening income disparity in academic achievement is not a result of widening racial gaps in achievement, either. The achievement gaps between blacks and whites, and Hispanic and non-Hispanic whites have been narrowing slowly over the last two decade

schools don’t seem to produce much of the disparity in test scores between high- and low-income students.

That isn’t to say that there aren’t important differences in quality between schools serving low- and high-income students — there certainly are — but they appear to do less to reinforce the trends than conventional wisdom would have us believe.

The academic gap is widening because rich students are increasingly entering kindergarten much better prepared to succeed in school than middle-class students. This difference in preparation persists through elementary and high school.

The average 9-year-old today has math skills equal to those her parents had at age 11, a two-year improvement in a single generation. The gains are not as large in reading and they are not as large for older students, but there is no evidence that average test scores have declined over the last three decades for any age or economic group.

the incomes of the rich have grown faster over the last 30 years than the incomes of the middle class and the poor. Money helps families provide cognitively stimulating experiences for their young children because it provides more stable home environments, more time for parents to read to their children, access to higher-quality child care and preschool

one part of the explanation for this is rising income inequality

High-income families are increasingly focusing their resources — their money, time and knowledge of what it takes to be successful in school — on their children’s cognitive development and educational success. They are doing this because educational success is much more important than it used to be, even for the rich.

even though middle-class and poor families are also increasing the time and money they invest in their children, they are not doing so as quickly or as deeply as the rich.

from 1972 to 2006 high-income families increased the amount they spent on enrichment activities for their children by 150 percent, while the spending of low-income families grew by 57 percent over the same time period

the amount of time parents spend with their children has grown twice as fast since 1975 among college-educated parents as it has among less-educated parents.

much of our public conversation about education is focused on the wrong culprits: we blame failing schools and the behavior of the poor for trends that are really the result of deepening income inequality and the behavior of the rich.

not only are the children of the rich doing better in school than even the children of the middle class, but the changing economy means that school success is increasingly necessary to future economic success, a worrisome mutual reinforcement of trends that is making our society more socially and economically immobile.

the rapid growth in the rich-poor educational gap provides a ray of hope: if the relationship between family income and educational success can change this rapidly, then it is not an immutable, inevitable pattern. What changed once can change again. Policy choices matter more than we have recently been taught to think.

how can we move toward a society in which educational success is not so strongly linked to family background? Maybe we should take a lesson from the rich and invest much more heavily as a society in our children’s educational opportunities from the day they are born. Investments in early-childhood education pay very high societal dividends. That means investing in developing high-quality child care and preschool that is available to poor and middle-class children. It also means recruiting and training a cadre of skilled preschool teachers and child care providers.

improving the quality of our parenting and of our children’s earliest environments may be even more important. Let’s invest in parents so they can better invest in their children.

Fundamentally, it means rethinking our still-persistent notion that educational problems should be solved by schools alone.

Accepting defeat and recognizing the results of a public poll is a cultural problem that cannot be solved overnight.

Leaders of the Islamic Action Front did not even recognize what observers had noted about the elections: that they were relatively free and fair.

Absent also are independent cultural figures who should be chiming in with their position in regards to any national event.

But what the elections have shown is that even if changes are made to the electoral process, a much more important change is required, namely of the culture of the citizenry: to believe in the system, accept its results and have the courage and sportsmanship to admit defeat.

This article was first published in the Jordan Times on Jan. 30, 2013.

If you look at exit polls of white voters only, Bump writes, Trump was clearly “earning more support from lower-income whites than wealthier ones.” Others have noted that exit polls diverged more sharply on racial lines than by income, and that Trump played on racial fears openly in his campaign. They argue that what triumphed on Tuesday was white racism.

That strikes me as true. And it also strikes me as true that white workers were acting out of a deep economic grievance on Tuesday. Argument A doesn’t falsify Argument B, in this case

In the nineteen-thirties, Germans suffered terrible economic pain—and many turned openly and violently anti-Semitic. It has been suggested that people find it easier to sustain moral virtues like racial tolerance, fairness, and open-mindedness when they’re prospering. The idea is a little discomfiting to conventional understandings of moral autonomy and personal responsibility. It suggests that it is impossible to provide ethical leadership for people without also attending to their material welfare—and that it is dangerous morally as well as materially for a demagogue to promise to solve an economic problem that he cannot.

Anger over the jobs lost to free trade was a hallmark of Trump’s campaign, and as it happens, in Brennan’s “Against Democracy”—as well as in books by Bryan Caplan and Ilya Somin that Brennan drew on to support his case—voters’ mistrust of free trade is commonly cited as an example of their ignorance.

According to Brennan and his allies, economists agree almost unanimously that free trade boosts a nation’s overall welfare. In March, 2012, when the University of Chicago Booth School of Business polled a panel of economic experts, fifty-six per cent agreed and another twenty-nine per cent strongly agreed that “Freer trade improves productive efficiency and offers consumers better choices, and in the long run these gains are much larger than any effects on employment.

In June, 2012, half of the same panel of experts agreed and another thirty-three percent strongly agreed that “Some Americans who work in the production of competing goods, such as clothing and furniture, are made worse off by trade with China.”

The professional consensus among economists, in other words, isn’t that free trade helps everyone; it’s that free trade so benefits the country as a whole that the government should find it easy to compensate the subset of citizens hurt by it—those who lose their jobs because workers abroad displace them.

In practice, such citizens are rarely given adequate compensation.

The upshot is that this election year, we’re divided not only by political party and ideology, but also by identity. So the weave of our national fabric unravels. And while our eyes have mostly been on Donald Trump and Hillary Clinton, the nation’s history is being written not just in the capital and grand cities but also in small towns and etched in the lives of ordinary people.

I hope Trump and his aides will soon come to recognize that words have consequences that go far beyond politics, consequences that cannot be undone

Yet if bigotry has been amplified by his candidacy, let’s remember that there are still deep reservoirs of social capital — including in conservative neighborhoods — that have proved impervious to Trump’s insinuations.

the Church in no way disputes the fact that market capitalism is by far the least worst means of raising standards of living and ending poverty and generating wealth that can be used to cure disease, feed the hungry, and protect the vulnerable. What the Church is disputing is that, beyond our daily bread, material well-being is a proper criterion for judging human morality or happiness. On a personal level, the Church teaches, as Jesus unambiguously did, that material goods beyond a certain point are actually pernicious and destructive of human flourishing.

Could anyone have offered a more potent critique of current Republican ideology than John Paul II? Could anything better illustrate John Paul II’s critique of radical capitalist ideology than the GOP’s refusal to be concerned in any way about a fundamental question like access to basic healthcare for millions of citizens in the richest country on earth?

there is a risk that a radical capitalistic ideology could spread which refuses even to consider these problems, in the a priori belief that any attempt to solve them is doomed to failure and which blindly entrusts their solution to the free development of market forces.

the Pope is not making an empirical observation. In so far as he is, he agrees with you. What he’s saying is that this passion for material things is not what makes us good or happy. That’s all

if the mania for more and more materialist thrills distracts us from, say, the plight of a working American facing bankruptcy because of cancer, or the child of an illegal immigrant with no secure home, then it is a deeply immoral distraction.

material goods are not self-evidently the purpose of life and are usually (and in Jesus’ stern teachings always) paths away from God and our own good and our own happiness.

Christianity is one of the most powerful critiques of radical market triumphalism.

how Finland does it: rather than “trying to reverse engineer a high-performance teaching culture through dazzlingly complex performance evaluations and value-added data analysis,” as we do, they ensure high-quality teaching from the beginning, allowing only top students to enroll in teacher-training programs, which are themselves far more demanding than such programs in America. A virtuous cycle is thus initiated: better-prepared, better-trained teachers can be given more autonomy, leading to more satisfied teachers who are also more likely to stay on.

Ripley made the canny choice to enlist “field agents” who could penetrate other countries’ schools far more fully than she: three American students, each studying abroad for a year.

yet another difference between the schools in top-performing countries and those in the United States. In Tom’s hometown high school, Ripley observes, sports were “the core culture.” Four local reporters show up to each football game. In Wroclaw, “sports simply did not figure into the school day; why would they? Plenty of kids played pickup soccer or basketball games on their own after school, but there was no confusion about what school was for — or what mattered to kids’ life chances.”

“In Korea, the hamster wheel created as many problems as it solved.” Still, if she had to choose between “the hamster wheel and the moon bounce that characterized many schools in the United States,” she would reluctantly pick the hamster wheel: “It was relentless and excessive, yes, but it also felt more honest. Kids in hamster-wheel countries knew what it felt like to grapple with complex ideas and think outside their comfort zone; they understood the value of persistence. They knew what it felt like to fail, work harder and do better. They were prepared for the modern world.” Not so American students, who are eased through high school only to discover, too late, that they lack the knowledge and skill to compete in the global economy.

Poland, a country that has scaled the heights of international test-score rankings in record time by following the formula common to Finland and South Korea: well-trained teachers, a rigorous curriculum and a challenging exam required of all graduating seniors

Ripley explains why: Historically, Americans “hadn’t needed a very rigorous education, and they hadn’t gotten it. Wealth had made rigor optional.” But now, she points out, “everything had changed. In an automated, global economy, kids needed to be driven; they need to know how to adapt, since they would be doing it all their lives. They needed a culture of rigor.”

The question is whether the startling perspective provided by this masterly book can also generate the will to make changes. For all our griping about American education, Ripley notes, we’ve got the schools we want.

The organizers assessed skills in literacy and facility with basic math, or numeracy, in all 23 countries. In 19 countries, there was a third assessment, called “problem-solving in technology-rich environments,” on using digital devices to find and evaluate information, communicate, and perform common tasks.

In all three fields, Japan ranked first and Finland second in average scores, with the Netherlands, Sweden and Norway near the top. Spain, Italy and France were at or near the bottom in literacy and numeracy, and were not included in the technology assessment.

The United States ranked near the middle in literacy and near the bottom in skill with numbers and technology. In number skills, just 9 percent of Americans scored in the top two of five proficiency levels, compared with a 23-country average of 12 percent, and 19 percent in Finland, Japan and Sweden.

“Our economic advantage has been having high skill levels at the top, being big, being more flexible than the other economies, and being able to attract other countries’ most skilled labor. But that advantage is slipping.”

Compared with other countries with similar average scores, the United States, in all three assessments, usually had more people in the highest proficiency levels, and more in the lowest. The country also had an unusually wide gap in skills between the employed and the unemployed.

In the most highly educated population, people with graduate and professional degrees, Americans lagged slightly behind the international averages in skills. But the gap was widest at the bottom; among those who did not finish high school, Americans had significantly worse skills than their counterparts abroad.

Among 55- to 65-year-olds, the United States fared better, on the whole, than its counterparts. But in the 45-to-54 age group, American performance was average, and among younger people, it was behind.

she diplomatically told her father that she, not he, was the person to solve the problem — an uncommon act that defies Pakistani familial tradition. As he walked away, she offered me a smirk of confidence.

The Malala I know transformed with age from an obedient, rather shy 11-year-old into a publicly fearless teenager consumed with taking her activism to new heights. Her father’s personal crusade to restore female education seemed contagious.

She hosted foreign diplomats in Swat, held news conferences on peace and education, and as a result, won a host of peace awards. Her best work, however, was that she kept going to school.

Malala beamed as I pressed her father to treat his wife as an equal. Sometimes I felt like her de-facto uncle. I could tell her father the things she couldn’t.

I was enamored by Malala’s presence ever since that sentence. But Swat was still too risky. For the first time in my career, I was in the awkward position of trying to convince a source, Ziauddin, that the story was not worth the risk.

I too wanted her to access the broader world, so during one of my final nights in Pakistan, I took a long midnight walk with her father and spoke to him frankly about options for Malala’s education. I was less concerned with her safety as the Pakistani military had, in large part, won the war against the Taliban. We talked about her potential to thrive on a global level, and I suggested a few steps toward securing scholarships for elite boarding schools in Pakistan, or even in the United States. Her father beamed with pride, but added: “In a few years. She isn’t ready yet.” I don’t think he was ready to let her go. And who can blame him for that?

Your ancestors came in chains. In your book the dream of the comfortable suburban life is a “fairy tale.” For you, slavery is the original American sin, from which there is no redemption. America is Egypt without the possibility of the Exodus. African-American men are caught in a crushing logic, determined by the past, from which there is no escape.

The innocent world of the dream is actually built on the broken bodies of those kept down below.

I think you distort American history. This country, like each person in it, is a mixture of glory and shame. There’s a Lincoln for every Jefferson Davis and a Harlem Children’s Zone for every K.K.K. — and usually vastly more than one. Violence is embedded in America, but it is not close to the totality of America.

In your anger at the tone of innocence some people adopt to describe the American dream, you reject the dream itself as flimflam. But a dream sullied is not a lie. The American dream of equal opportunity, social mobility and ever more perfect democracy cherishes the future more than the past. It abandons old wrongs and transcends old sins for the sake of a better tomorrow.

This dream is a secular faith that has unified people across every known divide. It has unleashed ennobling energies and mobilized heroic social reform movements. By dissolving the dream under the acid of an excessive realism, you trap generations in the past and destroy the guiding star that points to a better future.

Ben.Lynch Augusta, Georgia 1 day ago I've followed Mr. Coates for sometime now and tend to agree with his viewpoints. As a white southern male who works in our segregated education systems, it took years for me to actually apprehend my day to day interactions with black children in poverty. For the longest time, I simply couldn't understand the behaviors I saw, the reactions, and at first I reacted with contempt, but then I began to understand little by little. I don't think I can express it to anyone here, let alone Mr. Brooks, but it is something that one only appears to get by letting it sink into your bones day after day, hour after hour. The conditions are terrible and promise to remain so for the rest of my career. My students know, even if they lack the rhetorical chops to express it, that the game is rigged, that what we sell, meaning America at large, to make ourselves feel better, to feel just, is demonstrably a false bill of goods that does nothing to solve the actual problems of their life. These students are so used to being crushed that they can't even begin to articulate that they are being crushed because it's simply how it is. Some suppose Mr. Coates is overly dour, overly negative, but he provides a necessary contrapuntal to those who assume that the arc of the universe inevitably bends toward justice. Struggle can and often does end in defeat. The wicked often sleep as well as the just and sometimes better. The sins of the fathers remain fixed around the necks of the sons and daughters.

At their heart, both sources of hubris say that people with different views are illegitimate in one way or another. Someone who is illegitimate is not worth talking to, respecting, listening to, understanding, or even debating reasonably. Certainly not worthy of compromising with to solve the huge problems facing our nation.

Yet mastering these arduous skills is at the very essence of achievement. Most people work in groups. We do this because groups are much more efficient at solving problems than individuals (swimmers are often motivated to have their best times as part of relay teams, not in individual events). Moreover, the performance of a group does not correlate well with the average I.Q. of the group or even with the I.Q.’s of the smartest members.

Researchers at the Massachusetts Institute of Technology and Carnegie Mellon have found that groups have a high collective intelligence when members of a group are good at reading each others’ emotions

Participating in a well-functioning group is really hard. It requires the ability to trust people outside your kinship circle, read intonations and moods, understand how the psychological pieces each person brings to the room can and cannot fit together.

This skill set is not taught formally, but it is imparted through arduous experiences. These are exactly the kinds of difficult experiences Chua shelters her children from

Chua would do better to see the classroom as a cognitive break from the truly arduous tests of childhood. Where do they learn how to manage people? Where do they learn to construct and manipulate metaphors? Where do they learn to perceive details of a scene the way a hunter reads a landscape? Where do they learn how to detect their own shortcomings? Where do they learn how to put themselves in others’ minds and anticipate others’ reactions?

These and a million other skills are imparted by the informal maturity process and are not developed if formal learning monopolizes a child’s time.

classes were videotaped. This was not a vestige of Soviet surveillance. Rather, he wanted to critique how teachers interacted with — and nurtured relations between — children. Bogin and his staff often worked late into the night, reviewing footage and discussing methodology.

Life at New Humanitarian was full of academic Olympiads, poetry-reciting contests and quiz bowls. The school stressed oral exams, even in math, where children had to solve an equation at the blackboard and explain methodology.

Children were graded and ranked, with results posted. We were not accustomed to this: in Brooklyn, the school instilled an everyone’s-a-winner ethos. At New Humanitarian, Danya says, “they send an entirely different message to the kids: ‘Learning is hard, but you have to do it. You have to get good grades.’ ”

Danya, now nearly 14, was ambivalent about leaving, drawn toward being a teenager in New York City. But Arden and Emmett would have gladly stayed. “I feel like I’m tugged in two ways, and I have no idea what to do,” Arden told me last spring. “That’s the one problem with living abroad. You end up getting those weird feelings like, Oh, I can’t leave; I can’t stay.”

“Before Uber was a thing, I would rarely go to Hollywood,” said Drew Heitzler, an artist who lives in Venice, a potentially treacherous drive away. “The prospect of going to Hollywood on a weekend night, if I was invited to a party or an art event, it just wouldn’t happen. I would just stay home.”

Taxis here were often unreliable, he added, but ride shares are always just a swipe away.

“There’s a lot of New Yorkers here, and they’re saying it’s almost like New York.”

Once, only the privileged few, the studio bosses and pampered starlets, could afford to have a chauffeur and a waiting car to transport them around sprawling Los Angeles. Now anyone with a credit card can enjoy that freedom.

“Uber and Lyft have made it much more affordable, and encouraged people to venture out of their neighborhoods, and to explore.”

That is especially true of downtown Los Angeles, which is enjoying the double whammy of a recent cultural resurgence — partly bolstered by the Ace, which opened its hotel and performance space in a historic 1920s movie palace in January — and the car services that deliver once-reluctant visitors. Along with Santa Monica and West Hollywood, it is the area with the highest ridership, according to an Uber representative, though the company refused to release specific figures.

A night out in Los Angeles used to involve negotiating parking, beating traffic and picking a designated driver. Excursions from one end to the other — say, from the oceanfront city of Santa Monica to the trendy Silver Lake neighborhood on the eastern side — had to be planned and timed with military precision, lest they spiral into a three-hour commute. More often than not, they were simply avoided.

Grand Central Market, a food hall from 1917, has lately turned Smorgasburg-y; on weekends, preppily dressed crowds wait patiently for sandwiches from Eggslut. Outside, the street is blocked off for pedestrians, with cafe tables and umbrellas, and nearby is a linger-worthy bookstore and a retro barbershop with shuffleboard. Along Broadway, between discount stores and pupusa stands, are boutiques like OAK NYC and Acne Studios, the Swedish fashion label that opened a giant store there this fall.

“I find myself going down there a lot and taking friends that are coming to visit, because there’s so much cool stuff to do,” s

Ride sharing, some analysts say, has become a viable alternative to owning a car: between the cost of gas, insurance, garages and valet tips, it’s often more economical to get a lift in a professional’s Toyota than to drive solo in your own, and that’s without factoring in the mental cost of sitting in gridlock on Interstate 405.

A short ride through downtown in UberX, the company’s lower-priced service, introduced here last spring, can cost as little as $4, while parking lots charge $5 for 15 minutes.

In a nod to the city’s continued obsession with the status ride, the company recently implemented, in Los Angeles and Orange County only, UberPlus, with a fleet of BMWs and other luxury vehicles. Even with ride shares, what you pull up in matters.
