Apple's AI leadership changed hands twice in eighteen months, and each change originated outside the company's own AI organization. Ruoming Pang, the executive who led roughly 100 engineers building the models behind Apple Intelligence, departed for Meta Superintelligence Labs in July 2025, Bloomberg reported, at compensation figures that outpaced anything Apple was prepared to match 1. John Giannandrea, Apple's AI chief since 2018, followed him out the door less than a year later. By September 2026, Apple had replaced its AI leadership with outside hires, licensed a rival's model to rebuild Siri, and installed a hardware engineer, John Ternus, as chief executive.
The Meta Raid on Cupertino
Pang's departure initiated a pattern Apple absorbed for the rest of 2025. Meta poached two more Apple AI executives within ten days of Pang's exit, MacRumors reported July 17, 2025, part of the same hiring spree that built Meta Superintelligence Labs around nine-figure compensation packages 2. Ke Yang, who had led Apple's AI search project, followed the same route to Meta that October, according to MacRumors' reporting 3.
Three departures inside four months describe more than individual career moves; they describe a talent market where Apple's compensation structure, built for a company selling hardware at scale, competed directly against a rival willing to pay research-scientist salaries closer to professional-athlete contracts. Apple lost the negotiation each time.
The same Scale AI-fueled hiring campaign that installed Alexandr Wang as Meta's chief AI officer in June 2025 created the compensation ceiling Apple struggled to clear. Pang alone reportedly commanded tens of millions of dollars in annual pay at Meta, a figure that dwarfed anything Apple's hardware-centric compensation bands were built to offer a research scientist, let alone three of them inside a single year.
Giannandrea's Long Exit
His departure moved on a slower clock than Pang's or Yang's. Apple's own newsroom announced his retirement in December 2025, and the company let him transition through a "resting and vesting" period before his last day arrived in mid-April 2026 45. He resurfaced within two weeks at CuspAI, an AI-for-science startup, according to MacTech's reporting 6.
Apple named Amar Subramanya to lead its AI efforts in Giannandrea's place, a hire that inverted the company's usual instinct to promote from inside its own hardware-and-software culture, where executives typically spend a decade or more climbing a single organization before reaching the top tier. Subramanya arrived with a résumé built entirely outside Apple: he had led Google's Gemini Assistant work and contributed to Microsoft's Azure AI services before Cupertino recruited him 7. Giannandrea's remaining organizational responsibilities scattered, splitting toward chief operating officer Sabih Khan and services chief Eddy Cue, a redistribution that reads as an acknowledgment that absorbing Giannandrea's full portfolio exceeded what a single successor could manage.
Borrowing Gemini for Siri
Apple's response to its own depleted bench arrived in January 2026, when TechCrunch reported that Google's Gemini would power Apple's AI features, Siri chief among them 8. MacRumors confirmed the arrangement in April, describing a Gemini-powered Siri arriving later in the year at a price reportedly near $1 billion, with Apple demonstrating the integration publicly at WWDC that June 9.
Licensing a competitor's foundation model to run a flagship product represents an unusual concession for a company that has built its identity on vertical integration, from chip design through operating system through the assistant sitting atop both. The Gemini deal reads as a direct consequence of the Meta departures: Apple's internal models trailed the frontier, its leadership bench thinned further with each poaching round, and licensing bought the company time its internal research pipeline had yet to produce on its own.
The arrangement also inverts a rivalry Apple spent a decade framing the other way. Siri launched as Apple's answer to Google's search dominance and, later, to Google Assistant; a version of Siri now runs in part on Google's own model, a dependency Apple's marketing has historically avoided naming outright.
A Hardware Engineer at the Helm
Apple announced the resolution to its leadership question April 20, 2026: Tim Cook would become executive chairman, and John Ternus would become chief executive, effective Sept. 1, 2026 10. Ternus's background runs almost entirely through hardware. He joined Apple's product design team in 2001, rose to vice president of hardware engineering in 2013, and became senior vice president of hardware engineering in 2021, a role in which he oversaw the physical design of iPhone, Mac, iPad, Apple Watch and AirPods across more than a decade 10.
Board chair Arthur Levinson framed the choice around Ternus's technical depth, product focus and decades of institutional trust, distinct from any specific AI mandate, and Cook's own remarks about his successor emphasized engineering instinct and personal integrity over software strategy 10. Apple, in other words, chose a chief executive whose career centers on the physical objects Apple sells, at the exact moment competitors race to define AI as the layer that determines what those objects can do.
Reading the Transition as Strategy
Assembled in sequence, the four moves describe a company that treated its AI gap as a problem to route around, distinct from a problem its own succession planning was built to solve. Subramanya's hire imports AI leadership; Gemini's licensing deal imports AI capability; the Ternus transition confirms something different entirely — that Apple's board still weighs hardware execution, supply-chain command and product taste above any single AI credential when choosing who runs the company.
Set against Meta's raid-and-restructure pattern and OpenAI's shed-then-import approach across the same eighteen months, Apple's sequence looks the most defensive of the three: Meta bought talent to build ahead, OpenAI cut experiments to concentrate resources, and Apple patched departures with licensed capability and outside hires because its own bench, after three consecutive losses to Meta, had stopped offering an internal option.
TheStreet's framing of Ternus's first major test, published Sept. 2, 2026, centers entirely on a Sept. 9 product launch and the credibility of his own promotional language, leaving Siri, Gemini and the AI leadership Apple spent the prior year rebuilding entirely outside its frame 11. The test the market is actually watching may prove different from the one TheStreet named.
By the numbers
- July 7, 2025: date Bloomberg reported Ruoming Pang's departure from Apple for Meta Superintelligence Labs 1.
- Two: additional Apple AI executives Meta poached within ten days of Pang's exit, per MacRumors 2.
- December 2025: month Apple's own newsroom announced John Giannandrea's retirement 4.
- $1 billion: reported price of the Gemini-Siri licensing deal Apple struck with Google 9.
- April 20, 2026: date Apple announced John Ternus would become chief executive, effective Sept. 1 10.
- Sept. 2, 2026: publication date of TheStreet's assessment of Ternus's first major test 11.
What to watch
Ternus's Sept. 9 product launch will offer the first real test of whether "phenomenal" matches results, per TheStreet's framing, and whether the market extends that judgment to Apple's AI roadmap by extension. Subramanya's public debut leading Apple's AI organization will show whether an outside hire can move faster than the internal team Apple lost piece by piece through 2025. Gemini-powered Siri's actual release, once it ships broadly, will test whether licensing a rival's model closed the capability gap the departures opened or simply postponed the reckoning.
