New book by biographer Walter Isaacson explores the billionaire’s leadership style and ‘demon mode’
4 min
Simply put: Elon Musk can be a real jerk.
And that has probably helped and hurt him in business, according to a new biography by Walter Isaacson.
In “Elon Musk,” out Tuesday, Isaacson puts forth the idea of “demon mode” to explain the temperamental impulses behind some of the tycoon’s successes—and setbacks. But it isn’t just demon mode that has fuelled his rise. Isaacson details other teachable ways the billionaire’s methods have helped make him the world’s richest man.
Both sides of Musk are sure to become part of B-school lore for a new generation of would-be entrepreneurs and business managers picking and choosing which traits and tactics to emulate.
Isaacson had previously made the concept of the “reality distortion field” popular with his bestselling 2011 book about Apple co-founder Steve Jobs and his ability to bend perception to motivate others.
Demon mode was on display in 2018 as Musk struggled to ramp up production of Tesla’s Model 3 sedan, which nearly destroyed the electric-car company and which the CEO dubbed production hell.
That experience through hell, the book says, also helped Musk shape five commandments for how he wants problems solved by his workers across his companies, from rocket maker SpaceX to social-media platform X, formerly Twitter.
Musk, in the book, calls the framework for problem solving “the algorithm.” In short, Musk urges his employees to:
“His executives sometimes move their lips and mouth the words, like they would chant the liturgy along with their priest,” Isaacson wrote of Musk’s mantra.
In the book, Musk acknowledges he talks about the approach often. “I became a broken record on the algorithm,” Musk is quoted as saying. “But I think it’s helpful to say it to an annoying degree.”
The approach builds off a long-held method for problem solving touted by Musk called first principles, a reasoning that breaks tasks into their very basics without simply reverting to what has been done before.
“The algorithm is a five-step process for not only making good products and designing good products, but manufacturing them,” Isaacson said in an interview Monday.
“It begins with first principles. He says, question every requirement, and, by first principles he means, look down at the physics. If somebody says, no, we can’t build it at this price, he says, tell me how much the materials cost. Tell me exactly what’s involved here and then tell me you can or can’t do it.”
There are other lessons in the book that Musk has long practiced, such as never asking an employee to do something you aren’t willing to do (hence his sleeping on factory floors), hiring employees based on their attitude, and saying “it’s OK to be wrong. Just don’t be confident and wrong.”
Telling Musk bad news, however, has been seen by some employees as dangerous to one’s career.
“One of his problems is people sometimes are afraid to tell him the bad news,” Isaacson said. “Those who succeed around Musk are those who figure out you got to give him the bad news even if it’s going to result in some unpleasant scenes.”
Their fear is often rooted in demon mode.
Claire Boucher, known as the musician Grimes and the mother of three of Musk’s children, coined the term in an interview with Isaacson.
“Demon mode is when he goes dark and retreats inside the storm in his brain,” Boucher said in the book. “Demon mode,” she added, “causes a lot of chaos but it also gets s— done.”
And Musk has gotten a lot done, helping usher in the electric-car era as Tesla chief executive and igniting the commercial space race with SpaceX, which he founded. His messy stewardship of X, however, is testing public perception of his business genius.
Isaacson, who shadowed Musk for two years in reporting the book, saw demon mode in person several times along with other personalities that he described as ranging from silly to charming. He suggests the roots of the dark clouds come from the 52-year-old’s childhood in South Africa.
“It’s almost like Dr. Jekyll and Mr. Hyde where a cloud comes over and he gets into a trance and he can just be tough in a cold way,” Isaacson said. “He never gets really angry, never gets that physical, but coldly brutal to people and he almost doesn’t remember afterwards what he’s done. Sometimes I’ll say, why did you say that to that person? And he’ll look at me blankly as if he didn’t quite remember what happened while he was in demon mode.”
In one instance, Isaacson described seeing demon mode emerge when Musk saw SpaceX’s launchpad in South Texas empty late one evening.
“He orders a hundred people to come in from different parts of SpaceX from Florida, California so they can all work for 24 hours a day getting this thing done even though there was no need to,” Isaacson said.
Such surges seem to play in tandem to Musk’s need for drama.
“He is a drama magnet,” Musk’s younger brother, Kimbal, said in the book. “That’s his compulsion, the theme of his life.”
Isaacson cautions that readers shouldn’t come away thinking they can be just like Musk and automatically succeed. Rather, he said, readers should see both how leaders such as Musk and the late Jobs were effective and also take away cautionary tales.
“You don’t have to be this mean,” he said.
Still, throughout his book, Isaacson chases the question of whether Musk could be successful any other way.
“I try to show how that’s one of the strands in a fabric and as Shakespeare said, we’re molded out of our faults,” Isaacson said. “If we pull that strand out, you might not get the whole cloth of Elon Musk.”

Multinationals like Starbucks and Marriott are taking a hard look at their Chinese operations—and tempering their outlooks.
4 min
For years, global companies showcased their Chinese operations as a source of robust growth. A burgeoning middle class, a stream of people moving to cities, and the creation of new services to cater to them—along with the promise of the further opening of the world’s second-largest economy—drew companies eager to tap into the action.
Then Covid hit, isolating China from much of the world. Chinese leader Xi Jinping tightened control of the economy, and U.S.-China relations hit a nadir. After decades of rapid growth, China’s economy is stuck in a rut, with increasing concerns about what will drive the next phase of its growth.
Though Chinese officials have acknowledged the sputtering economy, they have been reluctant to take more than incremental steps to reverse the trend. Making matters worse, government crackdowns on internet companies and measures to burst the country’s property bubble left households and businesses scarred.
Now, multinational companies are taking a hard look at their Chinese operations and tempering their outlooks. Marriott International narrowed its global revenue per available room growth rate to 3% to 4%, citing continued weakness in China and expectations that demand could weaken further in the third quarter. Paris-based Kering , home to brands Gucci and Saint Laurent, posted a 22% decline in sales in the Asia-Pacific region, excluding Japan, in the first half amid weaker demand in Greater China, which includes Hong Kong and Macau.
Pricing pressure and deflation were common themes in quarterly results. Starbucks , which helped build a coffee culture in China over the past 25 years, described it as one of its most notable international challenges as it posted a 14% decline in sales from that business. As Chinese consumers reconsidered whether to spend money on Starbucks lattes, competitors such as Luckin Coffee increased pressure on the Seattle company. Starbucks executives said in their quarterly earnings call that “unprecedented store expansion” by rivals and a price war hurt profits and caused “significant disruptions” to the operating environment.
Executive anxiety extends beyond consumer companies. Elevator maker Otis Worldwide saw new-equipment orders in China fall by double digits in the second quarter, forcing it to cut its outlook for growth out of Asia. CEO Judy Marks told analysts on a quarterly earnings call that prices in China were down roughly 10% year over year, and she doesn’t see the pricing pressure abating. The company is turning to productivity improvements and cost cutting to blunt the hit.
Add in the uncertainty created by deteriorating U.S.-China relations, and many investors are steering clear. The iShares MSCI China exchange-traded fund has lost half its value since March 2021. Recovery attempts have been short-lived. undefined undefined And now some of those concerns are creeping into the U.S. market. “A decade ago China exposure [for a global company] was a way to add revenue growth to our portfolio,” says Margaret Vitrano, co-manager of large-cap growth strategies at ClearBridge Investments in New York. Today, she notes, “we now want to manage the risk of the China exposure.”
Vitrano expects improvement in 2025, but cautions it will be slow. Uncertainty over who will win the U.S. presidential election and the prospect of higher tariffs pose additional risks for global companies.
For now, China is inching along at roughly 5% economic growth—down from a peak of 14% in 2007 and an average of about 8% in the 10 years before the pandemic. Chinese consumers hit by job losses and continued declines in property values are rethinking spending habits. Businesses worried about policy uncertainty are reluctant to invest and hire.
The trouble goes beyond frugal consumers. Xi is changing the economy’s growth model, relying less on the infrastructure and real estate market that fueled earlier growth. That means investing aggressively in manufacturing and exports as China looks to become more self-reliant and guard against geopolitical tensions.
The shift is hurting western multinationals, with deflationary forces amid burgeoning production capacity. “We have seen the investment community mark down expectations for these companies because they will have to change tack with lower-cost products and services,” says Joseph Quinlan, head of market strategy for the chief investment office at Merrill and Bank of America Private Bank.
Another challenge for multinationals outside of China is stiffened competition as Chinese companies innovate and expand—often with the backing of the government. Local rivals are upping the ante across sectors by building on their knowledge of local consumer preferences and the ability to produce higher-quality products.
Some global multinationals are having a hard time keeping up with homegrown innovation. Auto makers including General Motors have seen sales tumble and struggled to turn profitable as Chinese car shoppers increasingly opt for electric vehicles from BYD or NIO that are similar in price to internal-combustion-engine cars from foreign auto makers.
“China’s electric-vehicle makers have by leaps and bounds surpassed the capabilities of foreign brands who have a tie to the profit pool of internal combustible engines that they don’t want to disrupt,” says Christine Phillpotts, a fund manager for Ariel Investments’ emerging markets strategies.
Chinese companies are often faster than global rivals to market with new products or tweaks. “The cycle can be half of what it is for a global multinational with subsidiaries that need to check with headquarters, do an analysis, and then refresh,” Phillpotts says.
For many companies and investors, next year remains a question mark. Ashland CEO Guillermo Novo said in an August call with analysts that the chemical company was seeing a “big change” in China, with activity slowing and competition on pricing becoming more aggressive. The company, he said, was still trying to grasp the repercussions as it has created uncertainty in its 2025 outlook.
Few companies are giving up. Executives at big global consumer and retail companies show no signs of reducing investment, with most still describing China as a long-term growth market, says Dana Telsey, CEO of Telsey Advisory Group.
Starbucks executives described the long-term opportunity as “significant,” with higher growth and margin opportunities in the future as China’s population continues to move from rural to suburban areas. But they also noted that their approach is evolving and they are in the early stages of exploring strategic partnerships.
Walmart sold its stake in August in Chinese e-commerce giant JD.com for $3.6 billion after an eight-year noncompete agreement expired. Analysts expect it to pump the money into its own Sam’s Club and Walmart China operation, which have benefited from the trend toward trading down in China.
“The story isn’t over for the global companies,” Phillpotts says. “It just means the effort and investment will be greater to compete.”
