Cook bows out, Ternus takes the stage: Apple is completing a daring leap from an "operational empire" to an "engineering fortress."

Writing by: Web4 Research Center

On April 20th, local time in the United States, Apple’s official website released a brief statement. The 65-year-old Tim Cook will step down as CEO, effective September 1, 2026, with Senior Vice President of Hardware Engineering John Ternus succeeding as CEO, and Cook will become Chairman of the Board. After the announcement, Apple’s stock price slightly declined after hours by less than 1%.

Less than 1% fluctuation, like a stone swallowed by the ocean. The market seems to have been prepared for this answer long ago.

This is the first CEO transition at Apple since 2011. Fifteen years ago, Cook took over just before Jobs’ passing, with no one able to predict the company’s future direction. Fifteen years later, the result is marked by a number: a $4 trillion market value. From $350 billion to $4 trillion, an increase of over 10 times.

But beyond the numbers, there are deeper questions worth asking. As a Web4 research center focused on AI and blockchain frontiers, we are more concerned not with the business story of this leadership change itself, but with: behind this transfer of power at the world’s largest tech company, how will the competitive landscape of the AI era be rewritten? And will the hidden cryptographic undercurrent in Apple’s ecosystem usher in new variables under the new leadership?

Let’s start with the person taking over.

1. The Cook Era, a Mirror of Glory

Looking at Cook’s tenure data, it’s hard not to be struck. Apple’s market value expanded from about $350 billion to $4 trillion, annual revenue from the 2011 fiscal year’s $108 billion to over $416 billion in 2025, nearly quadrupling. The number of active devices worldwide surpassed 2.5 billion, with more than 500 retail stores. The New York Times commented plainly: this marks the end of one of the most successful management tenures in American business history.

These figures form a mirror reflecting Cook’s legacy at Apple. But this mirror has two sides.

From the product line perspective, under Cook, Apple launched the Apple Watch, AirPods, and the Vision Pro virtual reality headset, leading the historic shift of the Mac series to self-developed Apple Silicon chips. Service business grew from less than $3 billion in 2011 to a hundred-billion-dollar scale, becoming a new profit engine. These achievements are solid enough.

However, the other side of the mirror is equally clear. The Wall Street Journal pointed out that after the iPhone, Apple’s most successful products are AirPods and Apple Watch, but their scale cannot compare to the iPhone. Vision Pro sales are poor, and the automotive project has been halted. Cook is known as an operational master, but the outside world has continued to criticize that Apple no longer has the disruptive innovation it had in the Jobs era. The BBC bluntly stated: Apple’s product line has basically stagnated.

Cook made Apple the most profitable company in the world, but he did not produce the next iPhone.

This statement is especially painful today, because the bell of the AI era has already sounded. Research firm Forrester’s chief analyst Dipanjan Chatterjee put it more straightforwardly: Cook has not brought the company a product like the iPhone that can allow successors to continue success for another 20 years. This is the most thorny question left by Cook for the “third generation.”

So, who will answer this question?

2. Ternus, a Hardware Engineer’s Coronation

John Ternus is 50 years old, about 15 years younger than Cook. When he joined Apple in 2001, Steve Jobs was in the midst of his comeback, and as part of the product design team, he experienced firsthand the immersion in Apple’s engineering culture. He graduated from the University of Pennsylvania with a degree in Mechanical Engineering, and over the next 25 years, he dedicated almost his entire career to Apple.

Bloomberg summarized his career style in one sentence: “Ternus’s achievements stand out because he oversaw the expansion of the iPad product line, as well as the R&D of AirPods and the company’s first 5G smartphone.” Not romantic, not legendary, but sufficiently hardcore.

Within Apple, Ternus is most praised for leading the transition of the Mac from Intel to self-developed chips. The release of the M1 chip in 2020 not only salvaged the declining reputation of the Mac series since 2016 but also proved that Apple has the ability to control its destiny at the most core hardware level. Since then, he has been responsible for hardware engineering across the entire product line, including iPad, iPhone, and Apple Watch.

Fortune magazine made a key judgment: Ternus is a true engineer, and hardware strength is crucial for Apple’s AI strategy. Apple’s hardware is ultimately what determines consumer acceptance of AI. “By promoting a chief product architect, Apple bets that the ultimate winner in the AI era will be those companies that control the final and most valuable part of user experience.”

This reveals the deepest logic behind Apple’s leadership change. Cook is a supply chain management genius, having built the most efficient global supply chain system, reducing inventory cycles from months to days, keeping Apple’s profit margins industry-leading. Ternus is a hardcore engineer, whose entire career has been answering one question: how to make all parts work together in the most elegant way.

From “operation-driven” to “engineering-driven,” this is the clear signal Apple is sending.

Business Insider’s comment hits the mark: Apple chooses not to compete with Google, Meta, or OpenAI by burning money on AI models, but instead waits for competitors to exhaust themselves, then collects rent from 3 billion iPhones. The success or failure of this strategy depends not on whether Apple can develop a better large model than GPT, but whether it can produce hardware that best fits AI experiences. Ternus’s mission is clear: leverage Apple’s unparalleled hardware layout to build the infrastructure indispensable in the AI era.

What does this mean? It means Apple’s AI path is not a cloud-based parameter race, but a reshaping of experience at the terminal. As AI models become increasingly similar, what truly influences user choice is whether the device in hand can make AI “seamless and unobtrusive.” This is the core capability accumulated over Ternus’s 25 years of hardware engineering.

At this point, the main thread of AI is already clear. But beneath the surface, there is a more hidden line.

3. Apple’s Gravity in the Crypto World

In November 2021, Cook publicly admitted for the first time that he personally owns cryptocurrencies. In September 2025, he reaffirmed that he owns Bitcoin and Ethereum, citing diversification and in-depth research as reasons.

But he also drew a clear line: Apple will not hold crypto assets, nor accept cryptocurrency as a means of payment. Personal is personal, company is company—clear boundaries.

However, beyond these boundaries, Apple’s ecosystem’s relationship with the crypto world is far more complex than it appears. According to Counterpoint Research, up to 41% of first-time crypto users worldwide completed their first fund recharge via Apple Pay. In 2025, Mesh released a case of integrating stablecoin payments through Apple Pay, allowing merchants to accept Bitcoin payments and settle in USDC. In April 2026, Exodus launched similar features in five US states.

Apple has not actively entered the crypto field, but its payment network has become an indispensable infrastructure in the crypto world. It’s somewhat like Sisyphus in Camus’s writing: the crypto industry pushes a boulder uphill day after day, and Apple’s slope happens to be the smoothest.

After Cook became Chairman, he still maintains significant influence over crypto-related policies and global regulatory relations. His personal stance on crypto assets, combined with Apple Pay’s de facto infrastructure status in crypto payments, forms a covert undercurrent. No one knows when this undercurrent might surface, or whether Ternus, a purely hardware engineer, might one day reconsider Apple’s relationship with crypto assets.

But one thing is certain: Apple’s App Store’s mechanism of charging a 30% service fee on digital goods (including NFTs and crypto-related in-app purchases) continues. Regardless of whether management cares about digital assets, this vast ecosystem has already established an irreversible gravitational connection with the crypto world.

Apple is quietly building the most conservative yet most indispensable infrastructure.

4. AI and Crypto, Apple’s Dual Hidden Ploys

Now, let’s look at AI and crypto together.

Cook’s departure appears to be a smooth leadership transition for Apple on the surface. But from a Web4 perspective, this transition at least plants two hidden foreshadowings.

First, the path choice of AI strategy. Ternus inherits an empire worth $4 trillion, but this empire has not taken the lead in the AI race. Criticisms that Apple lacks cutting-edge AI technology are endless. Apple’s response is not to join the arms race of large models but to bet on deep integration of hardware and AI. In the AI era, software defines experience, but hardware determines boundaries. This is the core competitive advantage of Ternus’s 25-year engineering career.

Second, the silent infiltration of the crypto ecosystem. Apple has never explicitly included cryptocurrencies in its financial reports, but it has already become one of the largest global channels for crypto payments. As US stablecoin legislation continues to advance and the EU’s MiCA framework lays out compliance paths across 27 countries, Apple’s traditional reason for rejecting crypto assets—“regulatory uncertainty”—is gradually losing its validity. Cook’s personal holdings and the de facto infrastructure status of Apple Pay form two anchors of Apple’s crypto story. Although there is no official version yet, the material is already abundant.

These two lines, seemingly parallel, converge on a common theme: Apple is evolving from a product-centric company to a super-platform with an ecosystem as its moat. AI is the soul of the ecosystem, crypto is its blood. The soul needs hardware to carry it, the blood needs a network to flow. Ternus is responsible for the former, while Cook’s successors will continue to address the latter.

5. The Intersection of Rationality and Poetics

In the Chinese tech circle, some compare Cook to Sisyphus pushing the boulder uphill in Camus’s writing. After Jobs left, the huge stone Cook inherited was too heavy: the outside world always measures him by Jobs’s standards, but he never tried to be another Jobs. He simply pushed the supply chain, optimized profit margins, and increased market value day after day, until he pushed the boulder to the top of $4 trillion. He didn’t create a brand-new world, but he built the strongest fortress on the ruins of the old one.

Now, the boulder has been handed to Ternus. He doesn’t need to keep pushing the same stone, but to decide what the next mountain on the summit will look like.

OpenAI CEO Altman posted a tribute on X: “Tim Cook is a legend! Thank you for everything you’ve done.” Oculus founder Palmer Luckey also posted a tribute, deliberately writing his name as “Tim Apple”—a meme from 2019 when Trump mispronounced Cook’s name. Cook then calmly changed his Twitter surname to the Apple logo.

An ordinary person from a remote town in Alabama, majoring in industrial engineering, leading the world’s greatest company. This is not a legend of genius, but an epic of diligence.

But this epic has turned the last page.

Cook has stepped down, and the $4 trillion mark remains etched there.

Will Apple’s next $4 trillion be written in the same way?
