Apple's AI struggles intensify as key executive Robby Walker departs.
Apple is grappling with a significant leadership departure within its artificial intelligence division as Robby Walker, a senior AI executive, is set to leave the company. The move comes at a pivotal time for the tech giant, which has faced mounting pressure and internal challenges in the highly competitive field of artificial intelligence. Walker's exit highlights a period of turbulence and strategic realignment within Apple's AI teams, marked by a series of high-profile departures and struggles to keep pace with rivals in the rapidly advancing AI landscape. Walker, who has been with Apple since his startup, Cue, was acquired by the company in 2013, has been a central figure in its AI efforts.[1][2][3] His tenure saw him rise to oversee the development of Siri, Apple's ubiquitous virtual assistant.[4][5]
Walker's role became particularly scrutinized as Apple's ambitions for a more advanced, AI-powered Siri faced significant delays. The company had publicly touted new capabilities that would allow for more natural and complex interactions, but the rollout of these features was ultimately postponed.[6][7] This setback was a public acknowledgment of the difficulties Apple was facing in the AI race. Internally, Walker addressed the challenges with his team, reportedly using an analogy of attempting to swim to Hawaii and not reaching the destination despite swimming a great distance.[8] He acknowledged that the delays were "ugly and embarrassing," especially after the features had been promoted.[9][10] This period of struggle culminated in a significant organizational shift, with oversight of Siri moving from Walker and AI chief John Giannandrea to software chief Craig Federighi and Mike Rockwell, who led the Vision Pro team.[6][11][12] Though his responsibilities were reduced, Walker remained a key figure, transitioning to a new role leading a team focused on a new AI-powered web search system, internally known as the "Answers" project.[4][5][8] This initiative is seen as Apple's answer to competitors like Perplexity and ChatGPT, with a planned launch in 2026.[4][13]
The departure of Robby Walker is not an isolated incident but rather symptomatic of a broader trend within Apple's AI division, often described as an "AI brain drain." In recent months, a number of high-level AI engineers and executives have left the company, with many joining rival Meta Platforms.[14][7] This exodus includes Ruoming Pang, who was in charge of Apple's AI models team, and other key researchers.[7] The aggressive recruitment tactics of competitors, offering substantial compensation packages, have intensified the "AI talent war," putting pressure on Apple's ability to retain its top minds.[4] These departures raise significant questions about the internal culture and strategy within Apple's AI group. The company's famously secretive culture has reportedly been a point of friction for some AI researchers who are accustomed to a more open, academic-style environment of publishing and sharing their work.[15]
Apple's strategic approach to artificial intelligence has been notably more cautious than that of its competitors. The company has prioritized user privacy, focusing on on-device processing to a greater extent than rivals like Google and Microsoft, who leverage vast amounts of cloud-based data.[16][17] This privacy-centric stance, a cornerstone of Apple's brand identity, presents unique challenges in developing large-scale AI models that benefit from extensive data analysis.[17] While this approach resonates with many consumers, it has also been cited as a factor in Apple's slower pace of innovation in generative AI.[7] CEO Tim Cook has acknowledged that Apple is often a latecomer to new technologies, preferring to enter a market when it can offer a more polished and refined product.[18] However, in the fast-moving world of AI, this "wait and perfect" strategy is being tested as competitors rapidly integrate advanced AI features into their products and ecosystems.[19][17][20]
In conclusion, Robby Walker's departure serves as a significant marker in Apple's ongoing journey to define its place in the age of AI. It underscores the internal pressures and leadership shuffles the company is navigating as it attempts to overcome development hurdles and a talent exodus. The implications of this executive change will be closely watched, as the success of future projects like the "Answers" search engine and a revitalized Siri will be crucial in determining Apple's ability to compete and innovate in a technology landscape increasingly dominated by artificial intelligence. The coming months will be critical in demonstrating whether Apple's methodical and privacy-focused strategy can ultimately triumph in the face of a rapidly evolving and fiercely competitive AI industry.
