The new leader of Apple at age 50

Text | Sleepy.md

Apple is about to experience its third leadership transition in company history.

In 1997, when the company was on the brink of bankruptcy, only 90 days away from collapse, it welcomed back the exiled missionary. With obsessive artistic intuition and a reality-bending force field, Jobs pulled Apple back from the edge of the cliff, thus beginning a golden age of genius and design.

At that time, Apple was hanging by a thread, craving a miracle, needing someone who could make people believe in the impossible. They found him.

In 2011, when the missionary left, and the anxiety over smartphone capacity and the wave of globalization roared in, the one who took the baton was an extremely calm supply chain master. Cook used precise inventory turnover rates to two decimal places and geopolitical savvy to push Apple’s market value from 350 billion dollars to four trillion, opening a silver age of business and capital.

Back then, Apple’s scale was growing, calling for order, needing someone who could make this massive machine operate with pinpoint accuracy, without a single flaw. They found him too.

Now it is April 2026.

The times have changed again. The frenzy around large models is destroying the old world map; the once-proud closed ecosystem appears sluggish and cumbersome under AI’s impact; and the tariffs hanging over Washington and the turbulent global supply chain have left this behemoth trapped.

At this critical moment of craving a new myth, Cook has handed over the baton.

It’s not another genius designer, nor another financial wizard. The one taking over this most precise and largest tech empire in the world is a reckless youth who once nearly destroyed the only CNC milling machine in the entire university.

His name is John Tenuis.

While everyone is feverishly trying to conjure a new world out of algorithms, Apple has entrusted its cards and future to someone who only believes in the laws of physics and respects the bottom line of hardware.

A mechanical engineer nicknamed “Destroyer,” who entered Apple in his early years amid the ashes of the VR bubble burst. He seemed out of place in this company with a severe design obsession. But what does he have that others don’t?

“Destroyer”

In the early 1990s at the University of Pennsylvania’s School of Engineering, Tenuis was not a prodigy shrouded in a halo from birth. His most prominent label was being a key player on the varsity swim team.

In 1994, he swept the 50-meter freestyle and 200-meter individual medley at university competitions, and with the record for most appearances in team history, he became the symbol of honor with the “All-Time Letter Award.”

Swimming was destined to be a dull discipline. It demanded no fancy tactics, only relentless repetition of strokes, kicks, and breathing underwater, until the movements were etched into muscle memory. In that pool, there were no shortcuts, no luck—only the accumulation of water droplets wearing down stone. This near-ascetic patience, refined over years, became the deepest color of his entire career.

His senior project was not chasing the hottest internet trends but creating a mechanical feeding arm for high-level paralysis patients, controlled by head movements to deliver food to the mouth. It was not a flashy project for high grades but a weighty attempt to solve real problems—a clunky, heavy iron lump.

But the most widely known incident at Penn was nearly destroying the university’s only CNC milling machine. Due to a mistake, the tool bit crashed directly into the machine bed. Committing such a basic error on an expensive, precise instrument earned him a loud, piercing nickname: “Destroyer.”

In the days that followed, that nickname shadowed him. He swallowed the laughter of classmates until many years later, when he returned as an Apple executive and, at graduation, openly shared this dark history on stage, causing the entire hall to burst into laughter.

He’s not a genius who never makes mistakes; he’s someone who messes up, gets ridiculed, but keeps working diligently. He doesn’t care about image—only results.

After graduating in 1997, he joined a startup called Virtual Research Systems, an early VR company, as a mechanical engineer, responsible for structural design of VR headsets and accessories. The company briefly existed during the VR boom of the 1980s and 90s, but like many startups that couldn’t survive the winter, it faded into history.

Looking back now, this past reveals a strange sense of fate and reincarnation. Over twenty years later, he personally led the creation of Apple’s Vision Pro, a spatial computing headset priced at $3,499, considered one of Apple’s biggest hardware bets ever. The lessons learned in the VR bubble were ultimately applied to the next VR gamble.

Armed with this somewhat unsuccessful history, he knocked on Apple’s door in 2001. That year, the iPod was just released, and Apple was eager to make a big splash in consumer electronics. But what awaited Tenuis was not the dazzling spotlight claiming to “change the world,” but the long, endless nights in Asian factories.

How did he climb step by step within Apple’s power structure, under the artistic halos of Jobs and Jony Ive?

From Screws to AirPods

When he first joined Apple, Tenuis’s first project was the Apple Cinema Display. This early high-end desktop monitor resembled a stern metal picture frame. On the back, several stainless steel screws were used for mounting. According to Apple’s industrial design standards, the screw heads had to be machined with concentric circle grooves, so that when light swept over them, they shimmered like CDs, adding texture.

The design drawings explicitly specified: 35 grooves.

At that time, he noticed that the number of grooves on the stainless steel screws on the back of the monitor was off. The drawings clearly called for 35 grooves, but the supplier only made 34.

This was a detail almost no one would notice. The monitor was wall-mounted, who would bother to count the grooves on the screws? But for that tiny discrepancy, he stayed late under the Asian factory’s incandescent lights, using a magnifying glass to count each micro-groove, even clashing fiercely with the supplier.

Later, recalling this incident at Penn’s graduation, he said a sudden thought flashed through his mind: “What am I doing? Would a normal person do this?”

It was indeed abnormal, but very Apple.

He proved his worth through this stubbornness, embodying Apple’s gene. Jobs once said that a great carpenter, even when no one is watching, would make the back panel as beautiful as the front. That late night in the Asian factory was his practice of that principle.

About three years later, he was promoted to manager. His first boss, Steve Siefert, assigned him a private, enclosed office. In the strict hierarchy of Silicon Valley giants, an independent office was a symbol of power. But he refused, moving his desk to the open area to sit among engineers. When Siefert retired in 2011 and again left the office to him, he refused once more.

He didn’t need a door to prove his status; he needed to stay close to the battlefield, to hear engineers discussing cooling, motherboards, and tolerances at any moment.

In 2005, he led the hardware engineering team for the G5 series iMac. It was from that time that he plunged into the complex Asian supply chain, gaining a raw, authentic understanding of manufacturing through hands-on experience on the assembly lines.

The birth of AirPods was his first career highlight. In 2013, he was promoted to Vice President of Hardware Engineering. Under his leadership, Apple launched AirPods in 2016. When the earbuds first appeared, they were met with widespread ridicule, mocked as “EarPods with the cord cut.”

But Tenuis chose silence. He knew better than anyone that squeezing complex Bluetooth chips, batteries, and sensors into that tiny space, making the latency between the two earbuds imperceptible, and ensuring enough power for a full day’s commute, was a miracle of engineering.

In the end, the market gave the answer. AirPods became Apple’s most successful wearable device, redefining the wireless earphone category and subtly reshaping how humans listen to the world in public.

He proved he was not just a screw-turning repairman but a behind-the-scenes driver turning concepts into phenomenally successful products.

Learning Patience

During Apple’s golden age, Jony Ive was second only to Jobs. His design philosophy became an unchallengeable gospel—even Cook, more business-oriented, had to yield slightly in the face of that extreme aesthetic. During Ive’s peak, Apple’s product decisions followed an unwritten rule: first determine the appearance, then figure out how to pack in the functions.

This logic sometimes created miracles, like the glass screen of the first iPhone or the wedge-shaped MacBook Air. But it also caused disasters.

In that period, in pursuit of extreme thinness, Apple made two critical mistakes: the Touch Bar and the butterfly keyboard.

To make the MacBook Pro look more futuristic, the design team decided to replace the traditional function keys with an OLED touch screen. To shave a few millimeters off the chassis, they invented the “butterfly keyboard,” with a very short key travel, making typing feel like tapping on a piece of wood, and a single speck of dust could cause the entire keyboard to fail.

These two designs plunged Apple’s reputation into a deep trough, even triggering a $50 million class-action lawsuit.

It was one of the darkest moments in Apple hardware history. As hardware lead, Tenuis was pushed to the forefront, bearing the brunt of criticism from media, users, and even internal staff.

At this moment, he showed a highly mature side—patience.

He didn’t blame the design team, nor did he clash with Jony Ive. He quietly swept the shattered glass into a dustpan, then spent years leading the effort to remove the Touch Bar, restoring the thicker chassis, the scissor-switch keyboard, MagSafe port, and SD card slot.

He stubbornly reclaimed the practicality that Apple had lost.

The 2021 MacBook Pro, dubbed “Apple’s apology to users” by the media, brought back all the ports that had been removed in recent years, thickened the chassis, but saw dramatic improvements in performance and battery life. Tenuis didn’t say “we fixed our mistakes” at the launch; he simply presented a better, more usable computer.

He didn’t shout slogans—he proved through action that a laptop should be primarily a useful tool, secondarily a piece of art.

But this experience left deep cracks in Apple’s power structure. According to Bloomberg, Tenuis’s relationship with the industrial design team was once quite tense. Some core designers believed he lacked the pursuit of ultimate beauty, and even tried to push another executive, Tang Tan, to succeed the then-head of hardware, Dan Riccio, instead of promoting Tenuis.

In the game of power, he’s not a flawless hero; he makes mistakes and can be pushed aside. But what’s precious about him is his ability to rebuild from ruins and continue doing what he believes is right.

“Forcing” the Creation of iPadOS, Changing “Physical Laws”

Inside Apple, the boundary between hardware and software is like a river dividing two kingdoms—mutually non-interfering, an unspoken rule. Hardware teams build the products; software teams make them usable. Overstepping often leads to conflict.

But Tenuis is an exception.

He participated in the development of every generation of iPad, from the first to the latest.

Over ten years, he watched the iPad he and his team built improve continuously. Screens grew larger, processors more powerful, even adding the expensive ProMotion refresh rate.

The hardware performance of the iPad far exceeds user needs, yet it still runs iOS, a mobile OS designed for phones.

Overcapacity in hardware, software that’s weak. It’s like fitting a tractor’s transmission into a Ferrari. No matter how tightly the hardware team tightens tolerances, what users get is still just a big video player.

His detailed data, user feedback, and reflections on product boundaries led him to approach software head Craig Federighi. This was a boundary-crossing move—hardware boss intervening in software. Such a thing is taboo in any big company. But he convinced Craig to develop a dedicated iPad OS, adding desktop-level multitasking, split-screen, and mouse support.

In 2019, iPadOS was officially launched. This move transformed the iPad from a big toy into a productivity tool, breaking the stereotype of “just a repairman.” With strong product intuition, he dared to cross boundaries and challenge internal bureaucracy.

He was also a proponent of LiDAR sensors. He proposed limiting this roughly $40 sensor to the Pro series, reasoning that Pro users are often tech enthusiasts willing to pay for this feature; ordinary users wouldn’t care. This judgment proved correct—the LiDAR became one of the most valuable differentiators of the iPhone Pro series.

What truly made him legendary was the 2020 transition to Apple Silicon. It was Apple’s most daring and successful hardware migration—shifting from Intel chips to Apple’s own chips. This meant abandoning a mature ecosystem and starting from scratch.

Tenuis led this transition. Reflecting on it, he said: “It felt like the laws of physics had been changed.”

He didn’t use flowery rhetoric, only the plain language of an engineer, expressing his shock at the chip’s energy efficiency. The chip enabled MacBook Air to have 18 hours of battery life, stay ultra-thin, and even operate without a fan. For someone who had counted screws in Asian factories for twenty years, it truly felt like the laws of physics had been rewritten.

In 2021, Dan Riccio stepped down, and Tenuis officially took over the entire hardware empire.

Taking over hardware was not a smooth road but a storm sweeping through the industry. A young man once called “Destroyer” finally stood at that position, but he faced an era unlike any Jobs had encountered.

The AI Earthquake

From 2023 to 2025, these were the most anxious years in Apple’s history.

The storm of large models swept through Silicon Valley. ChatGPT by OpenAI gained 8B users in two months, a speed that caused unprecedented panic among tech giants. Google declared a “red alert,” Microsoft invested $13 billion in OpenAI, and Meta poured nearly all resources into AI.

Apple’s AI experience was poor, with major Siri upgrades repeatedly delayed. The AI expert John Giannandrea, recruited from Google with a hefty price tag, faced a trust crisis. Internal cracks appeared, as the algorithm teams once entrusted with hope seemed unable to deliver satisfactory results to executives.

This was one of Apple’s most embarrassing moments. A company worth four trillion dollars, facing its most critical technological shift, appeared helpless. Amid this chaos, Tenuis showed a cold, decisive side.

In April 2025, Apple underwent a major internal restructuring. Giannandrea was stripped of leadership over Siri, and the robot development team, previously under the AI department, was directly placed under Tenuis’s hardware division.

This included a desktop-level smart device with a robotic arm and a home-following mobile robot. Bloomberg pointed out that this restructuring gave Tenuis control not only of hardware but also of some AI operating systems and algorithms.

When algorithms couldn’t be immediately monetized, Apple chose to trust hardware.

Then, in January 2026, the core and most sacred industrial design team’s reporting line was also transferred to Tenuis. He became the “Design Execution Initiator,” responsible for representing the design team at executive meetings. This was unimaginable in Jobs’s era—the design team, once a temple above all departments, now reports to a mechanical engineer.

Alongside this power shift, in September 2025, he launched the iPhone Air.

This phone was only 5.6mm thick (excluding camera bump), thinner than any competitor on the market, even thinner than a USB-C port’s diameter. To achieve this, engineers had to redesign antennas, batteries, and cooling structures, almost disassembling and rebuilding the entire phone.

Tenuis once said: “The best engineering and inventions always come from constraints. When you try to solve seemingly impossible problems, true creativity and invention are born.”

But he also has his flaws. After the launch of Vision Pro, users found serious audio delay issues when connecting AirPods Pro to the headset. Bloomberg reported that his first reaction was to trace responsibility rather than fix the problem immediately, causing internal dissatisfaction.

Additionally, he opposed adding cameras to the HomePod, believing it would increase costs, which led Apple to fall behind Amazon and Google in the smart speaker race. When Apple finally decided to launch a screen-equipped home device, competitors had already pulled ahead by years.

His “hardware fundamentalism” is both his moat and his limitation in the AI era. He faces a world where everyone tries to create worlds out of algorithms. His only cards are hardware.

“We Never Want to Release Junk”

In an interview in April 2026 about the affordable MacBook Neo, Tenuis was asked whether Apple would launch cheaper products to expand market share.

It’s a classic trap question—most Silicon Valley executives would respond with a polished PR line: “We are committed to providing the best experience,” “We will make the right decisions at the right time.” But Tenuis did not.

His answer was very firm: “We never want to release junk.”

That’s Tenuis. This phrase echoes the arrogance of Jobs’s era but is not exactly the same. Jobs’s arrogance was artistic; Tenuis’s is engineering arrogance. The former believed in beauty; the latter in standards.

Facing the surging AI tide, he didn’t issue grand timelines like other tech giants, nor did he promise to revolutionize the world. Apple’s marketing chief Joz once said AI is “a marathon, not a sprint,” but Tenuis firmly believes in the “inevitability” of spatial computing and virtual-real integration. He believes Apple’s 2.5 billion devices are the best carriers for AI, and edge computing is Apple’s true moat.

In this feverish era, such calmness may seem out of place. But that’s just who he is.

His personal hobby is cycling, and he enjoys taking colleagues to off-road rally racing in Washington State. Inside Apple, he is known as “approachable.”

At Penn’s graduation, Tenuis told the young audience:

“Always believe you are as smart as anyone in the room, but never think you know as much as they do.”

Apple’s three CEOs represent three different eras. Jobs was an artist who believed beauty could change the world; Cook was a manager who believed efficiency could conquer the world; Tenuis is an engineer who believes standards can safeguard the world.

There’s no hierarchy among these spirits—only choices of the times. In 2026, as AI storms, supply chains, and geopolitical games reshape the landscape, what Apple perhaps needs most is someone who can tighten every screw.

In “Moneyball,” Billy Beane used statistics to overturn traditional baseball recruiting logic, leading his team to the longest winning streak in history on the lowest payroll. The film’s famous line: “How can you not romanticize baseball?”

For John Tenuis, his romance isn’t about slogans to change the world but about machining every piece of aluminum to perfection, squeezing every bit of energy efficiency from each chip, and making the user experience of every keyboard so good it feels natural.

That sense of “naturalness” is the highest praise an engineer can give.

He is a builder of the Great Wall in ruins. Now, this wall is entrusted to him to guard.
