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.”

Gold miners are emerging as a compelling way to navigate market uncertainty, with analysts pointing to strong cash flows, attractive valuations and rising profit margins. As gold prices stabilize above US$4,000 an ounce, mining stocks could offer investors both downside protection and long-term upside.

Gold is one of the market’s go-to hedges in rocky times. Don’t forget that gold miners’ stocks are too.
The stock market’s gains in 2026 belie the rocky macroeconomic picture: elevated inflation, heightened geopolitical tensions, and jitters about the artificial-intelligence trade. That backdrop, in theory, should be the time for gold to shine. Instead, the price of the yellow metal has tumbled more than 5% so far, after last year’s blistering 65% rally. In part, the U.S. dollar’s recovery has stymied gold, which benefited from the greenback’s weakness in 2025.
Even with the precious metal’s recent weakness, gold mining stocks could be the best way to profit from this year’s uncertainty.
Gold miners “are a valuable hedge against macro risks that would likely be damaging for equities,” BCA Research’s Noah Weisberger and Rishabh Shah wrote this week.
Concerns about the Federal Reserve’s next moves to tackle inflation, the increasingly crowded AI trade, and steep valuations for tech stocks are just some of the drivers that could help gold’s price get on even footing— and lead to even bigger gains for miner stocks.
These stocks’ prices tend to outpace gold’s moves, because the companies have fixed operational costs. So when gold’s price rallies, their profit margins soar, and vice versa. For instance, the VanEck Gold Miners GDX +7.39% exchange-traded fund has fallen 11% this year as the metal has slumped.
Now, gold’s price just needs to stabilize to help miners’ stocks take off, and that seems to be happening. The precious metal has recently found support above the $4,000 level, and has stuck in a narrow range since the end of June. But its price rose ever so slightly in July, ending a four-month losing streak for the metal. Technical analysis also suggests that gold is due for a comeback.
Barron’s recently wrote that the pullbacks for both gold miners and the metal itself are overdone. Senior technical analyst Doug Busch noted that the VanEck ETF is on the “verge of a breakout” and has the potential to hit $11o in early 2027, up more than 40% from its current price.
Gold miners also have more than their role as a market hedge going for them. Their fundamentals are solid, too, says Chris Mancini, portfolio co-manager of the Gabelli Gold Fund.
“Precious metals miners are generating substantial amounts of free cash flow given profit margins of over $2,000 per ounce, and are returning this cash to shareholders through buybacks and dividends,” he said in an email.
“Buying the miners is a cheap way to get exposure to the price of gold,” he added. His fund owns Newmont NEM +6.71%, a Barron’s stock pick last year, and Agnico Eagle Mines as top holdings, as well as miners Northern Star Resources, Endeavour Mining, and Kinross Gold K+8.59%.
Miners are better businesses than they used to be, the BCA team added.
“Capex is more disciplined, margins are high and rising…and they are largely independent of the AI story,” Weisberger, BCA’s head of equities, and Shah, a senior analyst, wrote.
That last part is key. AI is disrupting the software industry and many other services and information-oriented businesses, and investors have piled into AI stocks. But ChatGPT, Claude, Grok, and other large-language models aren’t going to replace the need to mine for metals.
“Equity portfolios can benefit from exposure to quality that is uncorrelated to AI risk, and gold miners fit the bill,” the BCA team said.
They recommend that investors buy the VanEck Gold Miners ETF, which owns top miners such as Agnico, Barrick Mining ABX +7.24%, and Newmont.
An important bonus for big gold miners’ stocks is that their valuations are attractive after the gold’s pullback, too. The VanEck ETF is now trading at just a little more than nine times next year’s earnings estimates. That’s a big discount to its five-year average price-to-earnings ratio of 14, according to FactSet.
What’s more, the ETF is currently valued at a more than 50% discount to the S&P 500 SPX -0.17%, which is trading for about 19 times earnings estimates for 2027. Mining stocks have typically traded at just a 25% discount to the broader market over the past five years. So there is significant upside for the group if valuations move back toward normal levels.
One factor that complicates mining stocks as a market hedge, of course, is if stocks bounce back, which has been the case so far in August.
But both the market and economic outlooks remain cloudy, and investors remain nervous about the Fed’s next moves and AI stocks. Gold miners should do just fine, even if the anxious mood on Wall Street persists.
