In the high-stakes arena of Silicon Valley, where innovation often comes at the expense of sanity, Elon Musk’s empire is showing signs of fracture. As of early October 2025, a wave of departures has swept through all five of his flagship companies—Tesla, SpaceX, X (formerly Twitter), xAI, and The Boring Company—leaving behind a trail of burnout, whispered regrets, and empty desks. The culprit? Musk’s infamous expectation of 120-hour workweeks, a grueling marathon that has long defined his leadership style but now appears to be pushing even his most loyal deputies to the breaking point. What began as isolated exits has ballooned into a mass exodus, with over a dozen senior leaders jumping ship in the past quarter alone, according to insiders. For a man who prides himself on building the future, Musk now faces the stark reality that his vision might be leaving his workforce in ruins.

The exodus isn’t confined to one corner of Musk’s sprawling domain; it’s a synchronized hemorrhage across the board. At Tesla, the electric vehicle behemoth valued at over $1 trillion, sales have dipped amid a pivot toward AI and robotics, but the real hemorrhage is in the C-suite. Omead Afshar, a longtime Musk confidant and head of North American sales, was abruptly shown the door in August after a string of quarters marked by declining deliveries—blamed in part on Musk’s polarizing political tweets alienating progressive buyers. Afshar, who once joked about sleeping under his desk during Model 3 ramps, cited “strategic misalignment” in his farewell LinkedIn post, but sources whisper it was the endless nights debugging Cybertruck production lines that finally broke him. Joining him out the door: Daniel Ho, the engineer behind Tesla’s ill-fated $25,000 EV project, who defected to Google’s Waymo with a quiet nod to “seeking balance.” Tesla’s Fremont factory, once a badge of blue-collar grit, now hums with the fatigue of assembly workers pulling 12-hour shifts six days a week, their overtime pay no match for the mounting safety violations—three times the industry average, per recent labor reports.

Over at SpaceX, the rocket maker that’s redefined orbital economics, the departures sting deepest among the mission-critical teams. Milan Kovac, who helmed the Optimus humanoid robotics program—a Musk pet project blending SpaceX engineering with Tesla AI—resigned in late September after two years of all-nighters prototyping bipedal bots for Mars habitats. Kovac, a Slovakian wunderkind who’d endured the 2018 Falcon Heavy launch crunch, told colleagues he was “running on fumes,” his family time reduced to video calls from Boca Chica’s blast pads. Ashish Kumar, the AI lead for Optimus, followed suit, landing at Boston Dynamics with a severance package that bought him his first vacation in years. SpaceX’s Hawthorne headquarters, a labyrinth of whiteboards scrawled with orbital mechanics, now echoes with the ghosts of departed propulsion experts weary from 120-hour sprints to hit Starship’s 2026 lunar cadence. One anonymous engineer summed it up in a leaked Slack thread: “Elon’s math checks out for physics, but not for human bodies.”

X, the social media platform Musk rebranded from Twitter in a $44 billion bid for “free speech absolutism,” is bleeding talent faster than advertisers fled post-acquisition. The merger with xAI in March 2025 was meant to supercharge Grok’s integration, but instead, it amplified the chaos. Robert Keele, X’s general counsel who’d navigated the platform through EU hate-speech fines, bolted after 16 months, posting on LinkedIn about missing his toddlers’ bedtime stories amid midnight compliance reviews. “I love the mission, but not at the cost of my kids,” he wrote, a sentiment echoed by a dozen mid-level moderators who’d policed election misinformation marathons. X’s San Francisco offices, once buzzing with viral meme labs, now feel like a ghost town, with engineers decamping to Meta or Bluesky, lured by hybrid schedules and actual weekends. Musk’s recent 48-hour edict—demanding one-page “impact reports” from every employee—only accelerated the flood, with 15% of the engineering team tendering notices in a single week.

Perhaps the most acute crisis brews at xAI, Musk’s 2023 AI upstart aimed at “understanding the universe.” Here, the turnover reads like a revolving door comedy: Mike Liberatore, the CFO, lasted a mere 102 days before jumping to OpenAI, chronicling his exit with brutal candor on LinkedIn. “Seven days a week in the office; 120+ hours per week,” he detailed, describing all-hands coding sessions that blurred into dawn patrols. Liberatore’s departure wasn’t isolated; the general counsel followed, then the head of data ethics, each citing the soul-crushing grind of training Grok-4 amid Musk’s daily X rants demanding “sentient” breakthroughs by yesterday. xAI’s Palo Alto war room, stacked with whiteboards plotting neural net architectures, has lost 20% of its founding team since July, many to rivals like Anthropic, where founders preach “constitutional AI” over caffeine-fueled crusades. One ex-employee, speaking anonymously, likened it to “building the Death Star with no lunch breaks—epic, until your heart gives out.”

Even The Boring Company, Musk’s oft-mocked tunneling venture, isn’t spared. Steve Davis, the pragmatic president who’s overseen Vegas Loop expansions, has fielded quiet resignations from drill engineers exhausted by 24/7 shifts boring under LA traffic. A recent project to link Hughes Center stations hit delays not from geology, but from crew fatigue—workers nodding off mid-tunnel, their 120-hour logs a testament to the company’s “dig or die” ethos. Davis, one of Musk’s few enduring allies, has reportedly begged for “human limits” in internal memos, but to no avail.

At the epicenter of this storm sits Musk himself, a 54-year-old force of nature who’s long glorified the grind. In a 2024 BBC interview, he boasted of his own 120-hour weeks—”sleep, work, repeat, seven days a week, no choice”—framing it as the price of multi-planetary life. His companies’ cultures, forged in that furnace, reward the “hardcore”: lavish stock grants for those who sleep on factory floors, all-hands emails hailing “slave drivers” who self-flagellate for deadlines. Yet, as one former Tesla VP confided to the Financial Times, “Elon’s genius is matched only by his blindness to burnout. We’re not rockets; we don’t refuel on ambition alone.” The math is merciless: studies from Yale’s Center for Emotional Intelligence show that high-engagement teams under chronic stress—precisely Musk’s MO—see 20% spikes in attrition, with productivity cratering after 50 hours weekly. Slack’s global survey of 10,000 workers echoes this: forced overtime breeds resentment, not results, with 37% already logging after-hours weekly out of sheer survival.

Musk’s political forays have poured accelerant on the fire. His vocal support for far-right figures—from amplifying election denialism on X to endorsing European nationalists—has alienated the diverse talent pools his firms once drew. At Tesla, where a third of engineers hail from abroad, visa holders whisper about “optics risks” in group chats, accelerating exits to Rivian or Lucid. SpaceX, dependent on NASA contracts, frets over Musk’s DOGE role in the Trump administration, where he pushes similar 120-hour edicts for federal efficiency squads. “It’s not just the hours,” an xAI alum told MSNBC. “It’s defending the indefensible at dinner parties.” The Financial Times, after interviewing over a dozen insiders, dubbed it “the Musk paradox”: a leader whose deputies burn brightest—and fastest—under his glare.

The fallout is already rippling. Tesla’s Q3 2025 deliveries missed estimates by 5%, partly from supply chain snarls tied to absent robotics leads. SpaceX’s Starship Flight 10, slated for November, faces scrutiny from FAA auditors over “personnel stability” in safety protocols. X’s algorithm tweaks, meant to boost Grok engagement, have instead amplified toxicity, chasing off premium subscribers. xAI’s Grok-5 rollout, hyped for December, risks delays without its data wizards. The Boring Company’s Houston flood-tunnel pitch—touted as a 10% cheaper alternative—stumbles on crew retention for test bores.

Yet, amid the chaos, glimmers of defiance persist. Tesla Chair Robyn Denholm insists the company’s “bench strength is outstanding,” pointing to fresh hires from Big Tech lured by equity windfalls. SpaceX poaches relentlessly from Blue Origin, betting young Turks will stomach the pace. Musk himself, undeterred, fired off an X post last week: “The weak leave. The strong build the future. Who’s with me?” It garnered 50,000 likes, but replies brim with #MuskBurnout memes—cartoons of executives fleeing Hawthorne on unicycles.

For Musk, whose net worth hovers at $500 billion, this isn’t financial ruin; it’s existential. His companies aren’t just businesses; they’re extensions of his psyche—audacious bets on humanity’s leapfrog evolution. But as deputies like Liberatore and Kovac vanish into competitors’ arms, questions mount: Can the empire endure without the humans fueling it? Insiders predict a reckoning: mandatory wellness sabbaticals, AI-driven workload balancers, or even Musk’s unthinkable concession to 80-hour caps. One anonymous advisor nailed it: “The one constant in Elon’s world is how quickly he burns through deputies. But even furnaces run out of fuel.”

In Austin’s gigafactories and Boca Chica’s pads, the grind continues. Workers clock in at dawn, eyes hollow but hopeful, chasing the next breakthrough. Musk, ever the optimizer, might yet recalibrate—swapping sleep-deprived sprints for sustainable orbits. Until then, his five companies teeter on a razor’s edge: a testament to what’s possible when limits shatter, and a cautionary tale of what breaks when they do. As one departing X engineer posted en route to LinkedIn’s greener pastures: “Elon, the stars are worth it. But so are sunsets with my family.” In the race to Mars, perhaps the real frontier is balance.
