Insiders Say Apple’s Siri AI Demo Was Fiction: Not Even Demoware

Apple’s next-gen Siri demo at last year’s WWDC wasn’t just misleading—it may not have actually existed in any meaningful form, according to multiple engineers inside the company.

John Gruber of Daring Fireball says he’s spoken with trusted unnamed Apple software engineers off the record who were stunned by the 2024 keynote. Why? Because they’d never seen the personalized Siri feature in any internal iOS build before the demo aired. These aren’t low-level staffers—they’re people who believe they would have been involved if it were real. One told Gruber that the keynote was the first time they had heard of the feature. Let that sink in.

That alone would be damning, but Gruber also says several “little birdies” inside Apple confirmed the real reason we never saw the feature shown in a live, uncut demo: it simply didn’t work well enough to survive a single take. Latency was reportedly so bad that the keynote segment—where Siri finds a user’s mom’s flight—reportedly had to be cut together from multiple staged shots. There wasn’t a single moment that showed an actual conversation flowing from request to response (re-watch the demo at 1:22 here), as shown by Apple’s Kelsey Peterson, Director, Machine Learning and Al:

Imagine that I’m planning to pick my mom up from the airport, and I’m trying to figure out my timing. Siri is going to be able to help me do this so easily.

“Siri, when is my mom’s flight landing?”

What’s great is that Siri actually cross-references the flight details my mom shared with me by email with real-time flight tracking to give me her up-to-date arrival time.

Gruber’s sources say a version of the feature eventually reached a kind-of-working state, but was so unreliable it had to be scrapped. In Apple terms, it wasn’t just below their standards—it was flat-out unshippable.

And yet Apple executives, including Craig Federighi and Greg Joswiak, continue to insist the demo was based on real code, in a recent interview with Joanna Stern from the WSJ. Technically, that might be true. But as Gruber and others point out, “real code” doesn’t mean “working product.” You don’t get to film a commercial for a feature, promote it heavily, and then not ship it—and still claim it wasn’t vapourware with a straight face.

Even worse, Apple is now playing word games, says Gruber. Their public messaging says we’ll see the new Siri “in the coming year,” but multiple insiders confirmed to Gruber that this actually means sometime in 2026. That phrase gives the illusion of a 12-month window, when in reality Apple could delay until December of next year and still claim they delivered “on time.”

Gruber, who slammed Apple in March over broken Siri AI promises, isn’t done clearly in trying to hold the company accountable. His criticism likely resulted in Apple not providing executives to show up to his live post-WWDC keynote podcast for the first time since 2015. You can bet Apple isn’t happy with his critique of these Siri delays.

The most frustrating part? Apple hyped a smarter, AI-powered Siri overhaul as a key selling point when it launched the iPhone 16 series—convincing people to buy in on that promise. A year later, that version of Siri is nowhere to be seen. According to Bloomberg, it’s now delayed until next spring. Siri defenders are running out of excuses. Apple’s smart assistant, once first to market, is now far behind the competition—and it shows. What started as a head start has turned into a punchline. At this point, a full reboot isn’t just overdue—it’s necessary.
