Apple just announced its top AI executive is stepping down after Apple Intelligence failed to wow users and Siri’s big upgrade got pushed to 2026. A former Microsoft researcher is taking over—but is this a reset or a red flag for Cupertino’s AI ambitions? Details inside.

Have you ever watched a company you admire stumble right when the spotlight was brightest? That’s exactly what the past year felt like for anyone following Apple’s adventure into generative AI.

Monday evening, just as December began, the news dropped quietly but firmly: the man hired to put Apple on the AI map is stepping away. After years of leading one of the most secretive and ambitious AI efforts in Silicon Valley, the head of artificial intelligence is transitioning out of day-to-day leadership. And honestly? The timing couldn’t feel more loaded.

A Changing of the Guard at the Worst Possible Moment

Let’s be real—Apple Intelligence was supposed to be the moment Apple leapt from “late to the party” to “redefining the party.” Instead, many early users called it underwhelming. Reviewers pointed out it felt safe to the point of being boring. And perhaps the biggest gut punch? The much-hyped smarter Siri everyone was waiting for just got delayed all the way into 2026.

So when the company confirms that its top AI executive is moving to an advisory role next spring, eyebrows raise. This isn’t some mid-level departure. This is the person who reported directly to the CEO, the one brought in years ago specifically to close the gap with Google and OpenAI.

Who Was Behind Apple’s AI Push?

Brought on board in 2018 after Apple acquired his machine-learning startup, the outgoing leader quickly became the public face of Apple’s AI ambitions. He appeared at keynotes, defended on-device processing, and repeatedly promised that privacy and power could coexist in next-generation AI.

Under his watch, Apple built massive teams working on foundation models, hired aggressively from competitors, and poured resources into custom silicon that could run complex AI locally. Some of those efforts paid off beautifully—image generation on the latest devices is genuinely impressive when it works. But the overall package simply didn’t land the way anyone hoped.

Meet the New Leader Taking the Reins

Stepping into the role is an accomplished AI researcher who spent recent years at Microsoft. He’ll carry the title of vice president of AI and report to the longtime software chief—one step lower on the org chart than his predecessor held.

In many ways, this feels like a return to form. The software head has been deeply involved in AI strategy for years already, and insiders say he’s the one who truly drives cross-team alignment. Giving him direct oversight could actually streamline decisions that sometimes got bogged down in the past.

“Craig has been instrumental in driving our AI efforts, including overseeing our work to bring a more personalized Siri to users next year.”

Why Organizational Structure Suddenly Matters

Look, most consumers don’t care about org charts. But in tech, reporting lines send messages. Moving AI leadership from a direct report to the CEO down to a direct report to the software head signals something. Maybe it’s confidence that AI is now mature enough to be “just” a software problem. Or maybe it’s an admission that the moon-shot phase didn’t deliver fast enough.

Either way, investors noticed. Shares dipped slightly in after-hours trading before recovering most of the loss. The market seems to be taking a wait-and-see approach—hardly the vote of confidence Apple usually enjoys.

The Siri Delay That Changed Everything

If we’re being honest, the real story here isn’t the personnel change itself. It’s what the change says about the state of Apple’s AI roadmap.

When the company first unveiled its next-generation assistant, the demos were jaw-dropping. Siri understanding context across apps, pulling personal data securely, writing emails in your voice—it felt like the future. Then reality set in. Deadlines slipped. Features got scaled back. And eventually the whole overhaul got pushed deep into next year.

  • Original promise: major Siri upgrade in 2025
  • Current reality: core features arriving 2026 or later
  • User perception: Apple is playing catch-up, not leading

That gap between hype and delivery created fertile ground for today’s leadership transition to feel bigger than it might otherwise.

What Actually Went Wrong?

Several factors collided, from what industry observers can piece together.

First, Apple’s uncompromising stance on privacy meant most heavy lifting had to happen on-device. That’s noble, but it also imposes brutal hardware constraints. Competitors running massive cloud models simply have more room to swing for the fences.

Second, the company may have underestimated how fast the field was moving. While Apple was perfecting its first-generation foundation models, others released second- and third-generation systems that leapfrogged in capability.

Finally—and this is pure speculation but feels plausible—there might have been internal tension between the “ship something safe” camp and the “wait until it’s magical” camp. When you’re Apple, good enough rarely feels good enough.

Reasons for Cautious Optimism Moving Forward

That said, I’m not ready to write Apple’s AI obituary. Far from it.

The new structure could actually accelerate progress. Putting AI firmly under software leadership means tighter integration with iOS, macOS, and the broader ecosystem—exactly where Apple has historically crushed it. Remember how CarPlay went from afterthought to industry benchmark once Jony Ive’s design team got religion? Similar magic could happen here.

Apple still has advantages almost no one else can match:

  • Over a billion active devices as a deployment platform
  • Custom silicon that smokes general-purpose chips on efficiency
  • A user base famously willing to upgrade hardware regularly
  • Insane amounts of cash to throw at talent and compute

In my view, the company just needed to stop treating AI as a skunkworks project and start treating it as core platform infrastructure. This reorganization might be the signal that’s finally happening.

What Investors Should Watch Next

If you hold Apple stock—or you’re thinking about it—here are the milestones that actually matter over the next 12 months:

  1. Developer feedback at the next summer conference—will third-party apps finally get rich AI tools?
  2. Any preview of the delayed Siri features—even a limited beta would calm nerves
  3. Partnership announcements (yes, the OpenAI deal was just the beginning)
  4. Hardware reveals that lean harder into on-device AI performance

Miss another beat, and the narrative gets harder to control. Nail even two of those, and today’s news becomes a footnote.

The Bigger Picture for Big Tech

Zoom out, and this feels less like an Apple-specific story and more like growing pains for the entire industry. Every major player has hit turbulence:

  • Google stumbled hard with early Gemini image generation
  • Microsoft faced backlash over Recall privacy concerns
  • OpenAI continues to burn cash at historic rates
  • Meta keeps pivoting between open-source and closed models

Maybe the lesson is that generative AI is turning out to be more marathon than sprint. The companies that win won’t necessarily be the first to ship flashy demos. They’ll be the ones who ship features people actually use every single day without thinking twice.

And historically? That’s been Apple’s superpower.


So yes, today feels like a gut check moment. A high-profile departure right after a product cycle that didn’t land perfectly is never fun. But if this transition brings clearer focus, faster iteration, and deeper integration across the platform, it could end up being exactly what Apple needed.

Only time will tell. But one thing I’m certain of—2026 is going to be fascinating.

The only real mistake is the one from which we learn nothing.
