Steve Jobs taught Apple how to invent the future. Tim Cook taught it how to dominate the present. John Ternus now has to prove Apple can do both at once.
There are corporate successions, and then there are Apple successions. Few companies are so closely associated with the personality of the person standing at the top. That is partly because Apple has never really sold technology alone. It sells an idea of what technology should become next.
In September 2026, that responsibility changed hands for only the second time in modern Apple history. Tim Cook, chief executive for 15 years, became executive chairman. John Ternus — the mechanical engineer who joined Apple’s product design team in 2001 and eventually ran Hardware Engineering — became CEO.
His first major product event offered an almost suspiciously neat symbol for the transition: the iPhone Duo, Apple’s first folding iPhone. A familiar product, physically opening into something different.
That may also be the challenge facing Ternus. He has inherited perhaps the most successful consumer technology machine ever built. His job is not to rescue Apple. It is to make a company that has already won feel hungry again.
The Jobs era: Apple learned to say no
The mythology around Steve Jobs can obscure what was genuinely unusual about his leadership. Jobs was not simply a charismatic presenter who unveiled beautiful products. His defining skill was reduction.
Apple under Jobs became extraordinarily good at deciding what not to build, what features did not deserve to exist and what assumptions about computers could be discarded.
The iMac simplified the personal computer. The iPod simplified digital music. The iPhone collapsed a phone, an internet communicator and a music player into a device whose most radical feature was arguably what it removed: the permanent keyboard.
Jobs-era Apple repeatedly behaved as if customers could not vote on the future because the future had not been shown to them yet.
That approach produced extraordinary products, but it also created a problem no succession plan could solve cleanly. How do you replace a founder whose personality has become part of the product?
Tim Cook did not become Steve Jobs — and that was his greatest decision
When Cook became CEO in 2011, the easiest criticism was also the least useful: he was not Steve Jobs.
He never tried to be.
Cook’s Apple was less theatrical and more systematic. Where Jobs excelled at identifying the product that should exist, Cook built an organisation capable of producing, distributing and monetising Apple products on a scale that would have been difficult to imagine in 2011.
The numbers are staggering. Reuters reported that Apple grew from roughly $350 billion in market value when Cook took over to more than $4.5 trillion by the time he handed the CEO role to Ternus. Annual sales expanded from $108 billion to $416 billion, while profit rose to more than $112 billion.
But Cook’s most important achievement may have been less visible than an iPhone.
He institutionalised Apple.
Apple stopped being a company that seemed dependent on one extraordinary individual and became a machine capable of surviving generations of employees, products and economic cycles. Services turned the installed base into recurring revenue. Apple Watch and AirPods created enormous businesses around the iPhone. Apple silicon gave the Mac a new identity. The supply chain became a competitive weapon.
Cook proved something many people doubted in 2011: Apple could remain Apple without Jobs.
But success created a different Apple problem
The Cook era also produced a paradox.
The larger Apple became, the harder it became for any new product to matter financially. A fascinating device is not enough when the company already operates an iPhone ecosystem measured in billions of users.
And the misses became more conspicuous. Apple abandoned its long-running car project. Vision Pro demonstrated remarkable engineering but did not become a mass-market platform. Most importantly, the generative AI explosion moved faster than Apple’s initial response, leaving Siri looking increasingly dated beside a new generation of conversational systems.
This does not erase Cook’s record. It explains why the timing of Ternus’s arrival matters.
Apple does not need another operations revolution. It needs to decide what personal computing looks like when AI begins changing the interface itself.
John Ternus is a very Apple choice
Ternus is neither a celebrity outsider nor an obvious attempt to recreate Jobs.
He is an Apple lifer.
He joined the product design team in 2001, became a vice president of Hardware Engineering in 2013 and joined Apple’s executive team in 2021. Apple credits him with overseeing hardware work across iPhone, iPad, Mac, Apple Watch and AirPods, as well as work on reliability, materials, repairability and manufacturing.
That history matters because Ternus grew up professionally inside both previous Apple eras. He joined while Jobs was rebuilding the company. He rose through the organisation Cook scaled.
In that sense, Ternus is not a rejection of either man. He may be Apple’s attempt to combine their lessons.
The iPhone Duo is an intriguing first signal
Ternus’s first major launch as CEO could hardly have been more symbolic.
Apple entered foldables years after Samsung and Chinese manufacturers, then presented the iPhone Duo as if lateness itself were part of the strategy: wait, observe the weaknesses of the category and enter when Apple believes it can redefine the experience.
That is classic Apple behaviour. But putting a hardware engineer in the CEO chair as the company unveils its biggest iPhone form-factor change in years also feels consequential.
Ternus’s Apple may become more willing to rethink the physical objects around which the ecosystem is built.
The Duo should therefore be viewed as more than another expensive iPhone. It is the first major product marker of the post-Cook CEO era.
The real Ternus test is not hardware. It is AI.
This is where the story becomes more complicated.
Apple’s traditional advantage is integration. It controls silicon, hardware, operating systems, distribution and an enormous ecosystem of devices already sitting in pockets, homes and on wrists.
Generative AI threatens to rearrange that hierarchy.
If conversational agents become the primary way people interact with computers, the operating system could matter differently. Apps could matter differently. Even the smartphone could eventually matter differently.
For Ternus, therefore, winning in AI does not necessarily mean building the largest model or the loudest chatbot. Apple’s opportunity is to make intelligence disappear into the product.
A Siri that understands what is on your screen. AirPods that translate a conversation while you are having it. A Watch that interprets health patterns rather than merely recording them. A foldable iPhone that changes its interface depending on how it is being held. Macs powerful enough to run increasingly sophisticated models locally.
That is an Apple-shaped AI strategy.
But it must work. Privacy and integration are compelling differentiators only when the intelligence underneath them is competitive.
What should we expect from the Ternus era?
The safest prediction is that Apple will remain recognisably Apple. Ternus has spent a quarter-century inside the company, and Cook remains executive chairman. This is continuity, not revolution by outsider.
But there are several areas where the pressure for change is obvious.
First, hardware may become adventurous again. The iPhone Duo breaks the slab-phone template. Vision products remain a long-term attempt to move computing beyond rectangular screens. AirPods are evolving toward an always-available interface for AI. Apple Watch is becoming an increasingly sophisticated health computer.
Second, Apple Intelligence has to graduate from feature to platform. Ternus inherits the AI question Cook could not completely settle. The next several years will determine whether Apple’s ecosystem becomes its greatest AI advantage or whether that ecosystem is forced to accommodate intelligence built elsewhere.
Third, custom silicon will become even more important. Apple silicon transformed the Mac. Apple is increasingly controlling other critical components, including its own modem technology. In an AI world where efficiency, local processing and battery life matter enormously, controlling the chips may be as strategically important as controlling the operating system.
Finally, Ternus will need his own product. Not merely a better iPhone, Watch or Mac. Every defining Apple leader eventually becomes associated with a technological transition. Jobs had the Mac, iPod and iPhone revolutions. Cook presided over Apple Watch, AirPods, services and Apple silicon while scaling the ecosystem to unprecedented size.
Ternus will eventually need an answer to a deceptively simple question: what belongs to his Apple?
Three leaders, three different jobs
It is tempting to rank Apple CEOs by asking who was the greatest innovator. That misses what succession actually required.
Jobs had to save Apple and teach it to make products people did not know they wanted.
Cook had to prove that the company could survive its founder, then transform extraordinary products into one of history’s most formidable businesses.
Ternus inherits neither crisis.
His challenge may be subtler and, in some ways, harder: preventing success from becoming inertia.
Apple enters its third modern era with enormous advantages — billions of devices, custom silicon, unmatched ecosystem integration, extraordinary brand loyalty and financial resources few competitors can approach. But technology is entering another interface transition, and dominant companies rarely get to choose when those transitions arrive.
The Tech Boom take
Steve Jobs made Apple believe that technology could be intensely personal. Tim Cook proved that philosophy could be scaled to the entire planet.
John Ternus now has to decide what “personal” means when the computer begins to understand the person using it.
That is why his appointment is more interesting than a normal CEO succession. Apple is changing leaders at almost exactly the moment the industry is changing interfaces.
The iPhone Duo may ultimately be remembered as the first visible product of the Ternus era. But it probably will not define him.
Somewhere inside Apple today, there is likely a project — perhaps an AI experience, a wearable, a new form of spatial computing, or something we have not yet named — that will.
And when it arrives, the most important question will not be whether John Ternus can become the next Steve Jobs.
It will be whether Apple, for the third time, can become the next Apple.
