Apple to unveil AI upgrades at Cook's final WWDC before leadership transition

Siri could become as foundational as AirDrop itself
An upgraded AI assistant working across Apple's devices could reshape how users experience the company's ecosystem.

At Apple's annual developers conference in Silicon Valley, Tim Cook steps onto the stage for the last time as chief executive — a deliberate farewell before John Ternus assumes leadership in September. The occasion is less a product launch than a philosophical statement: that a company built on the seamless marriage of hardware and software is now staking its next chapter on artificial intelligence. Siri, long a symbol of Apple's unfulfilled promise in voice computing, is being reimagined as the connective tissue of an ecosystem that spans devices, contexts, and conversations — a quiet but consequential bet on what it means to be useful in an age of intelligent machines.

  • Apple enters WWDC trailing competitors in the AI race, and the pressure to demonstrate relevance — not just ambition — is acute.
  • Siri, once a novelty and now a liability in comparison to newer conversational AI systems, is being rebuilt from the ground up to hold memory, manage multi-step tasks, and move fluidly across devices.
  • The company is leaning on Google's Gemini model to power some features, a striking admission that even the world's most valuable company cannot always build what it needs alone.
  • Cook's fifteen-year tenure — which added over four trillion dollars in market value — closes with this conference, making every announcement carry the weight of both legacy and transition.
  • John Ternus, a twenty-five-year Apple veteran who has overseen iPhone, iPad, and Mac engineering, waits in the wings as the successor who must carry the AI pivot forward.
  • The trajectory is toward an Apple ecosystem where Siri becomes as invisible and indispensable as AirDrop — not a feature you think about, but one you cannot imagine working without.

Tim Cook will take the stage at Apple's developers conference Monday for the last time as chief executive — a farewell performance before John Ternus assumes leadership in September. The timing carries weight. WWDC, held at Apple's Silicon Valley headquarters and attended by engineers from roughly sixty countries, has always been about software — the invisible architecture beneath the devices. This year, that architecture is artificial intelligence.

The centerpiece is Siri. After more than a decade as part of Apple's identity, the voice assistant has grown brittle and dated, often forcing users to break complex requests into smaller pieces and start over with each exchange. Apple is expected to reimagine it as a true conversational AI — one that remembers prior exchanges, holds context across multiple steps, and works fluidly across iPhones, Macs, and iPads. If it succeeds, Siri could become as foundational to the Apple experience as AirDrop or Handoff, the features that already let users move work seamlessly between devices. That kind of deep integration is something competitors have struggled to replicate.

To get there, Apple is partnering with Google's Gemini model — a candid acknowledgment that even the world's most valuable company sometimes needs to borrow from rivals. The company has been open about playing catch-up in AI, and this conference is its most visible chance to show the gap is closing.

Cook's retirement, announced in April, marked the end of a fifteen-year tenure that grew Apple's market value by more than four trillion dollars. Ternus, who has spent twenty-five years at Apple and the last five overseeing engineering for its core hardware lines, is the natural heir — someone with the technical credibility to lead the company into its next era. What Cook frames at this WWDC will be the last narrative he sets before handing over the stage. The message, embodied in a rebuilt Siri, is that Apple is not abandoning what made it great — it is evolving it for an age when intelligence is the defining feature of every device.

Tim Cook will walk onto the stage at Apple's annual developers conference on Monday for what amounts to a farewell performance. It will be his last World Wide Developers Conference as chief executive before John Ternus takes over the company in September, ending Cook's fifteen-year tenure at the helm. The timing is deliberate, symbolic even—a final chance to set the tone for where Apple is headed before passing the keys to his successor.

The conference, held at Apple's Silicon Valley headquarters, draws thousands of software engineers from roughly sixty countries. Unlike the fall iPhone unveilings that dominate the tech calendar, WWDC has always been about the software layer, the invisible architecture that makes devices work. This year, that focus will center squarely on artificial intelligence. Apple has spent the last year watching competitors race ahead in the AI space, and the company is ready to show it has caught up.

The centerpiece of Apple's AI push will likely be Siri, the voice assistant that has been part of the company's ecosystem for more than a decade but has grown stale in recent years. Analysts expect Apple to reimagine Siri as something closer to a true conversational AI—a chatbot that remembers what you've asked before, that can hold a thread across multiple exchanges, and that can handle complex requests involving several steps in a single command. The current version of Siri is brittle by comparison, often requiring users to break tasks into smaller pieces and start fresh with each request.

What makes this version of Siri potentially powerful is the way it could weave through Apple's entire ecosystem. An upgraded Siri that works seamlessly across iPhones, Macs, and iPads—remembering context and managing tasks across all those devices—could become as foundational to the Apple experience as features like AirDrop or Handoff, which already let users move work fluidly between devices. That kind of integration is something competitors have struggled to achieve. Apple's advantage has always been control over both hardware and software; Siri could be the glue that makes that control feel less like a walled garden and more like genuine convenience.

Apple is leaning on Google's Gemini AI model to power some of these features, a partnership that underscores how even the world's most valuable company sometimes needs to borrow technology from rivals. The company has been candid about playing catch-up in the AI race, and this conference is its chance to show that the gap is closing.

Analysts are calling 2026 a transition year for WWDC itself. While hardware announcements are rare at the conference, there may be hints of Apple's plans to expand into new categories—foldables, wearables, smart home devices—through software and ecosystem updates aimed at developers. These breadcrumbs matter because they signal where the company sees opportunity beyond the iPhone, which has been the engine of Apple's growth for nearly two decades.

Cook's announcement of his retirement in April was a watershed moment. His fifteen years leading Apple saw the company's market value climb by more than four trillion dollars, a staggering figure that reflects the iPhone's dominance and Apple's ability to extract profit from hardware and services in ways few companies can match. Ternus, who has been at Apple for twenty-five years and spent the last five overseeing engineering for the iPhone, iPad, and Mac, is the natural successor—someone who understands the company's technical DNA and has the credibility with engineers to lead it forward.

What happens at this WWDC will be Cook's last chance to frame the narrative before Ternus takes the stage as the new leader. The message will be clear: Apple is not abandoning its core strengths, but it is evolving them. Siri is the symbol of that evolution—a feature that has been part of Apple's identity for years, now being rebuilt for an era when artificial intelligence is the defining technology.

The Hearth Conversation Another angle on the story
Inventor

Why does it matter that this is Cook's last WWDC? Isn't the technology the real story?

Model

The technology is the story, but the timing carries weight. Cook is essentially handing off the company at a moment when AI is reshaping everything. He gets to say one last time: here's where we're going. Then he leaves.

Inventor

And where is Apple going, according to what they're likely to show?

Model

Toward a Siri that actually understands context and remembers you. Right now Siri is almost useless for anything complex. The new version could work across your phone, your Mac, your iPad—all in conversation, all remembering what came before.

Inventor

That sounds like what other companies are already doing.

Model

They are. That's the point. Apple fell behind. They're using Google's AI model because they had to. But if they can make Siri feel native to their ecosystem in a way competitors can't, that's their edge.

Inventor

Is there risk in showing this now, before Ternus takes over?

Model

The risk is if it doesn't work as promised. But Cook's been running the company for fifteen years. He knows how to manage expectations. This is a controlled handoff, not a crisis.

Inventor

What does this say about Apple's future beyond phones?

Model

That they're thinking about it. Foldables, wearables, smart home—those categories are coming. But the real product is the ecosystem. Siri is the thread that ties it all together.
