Apple is facing another significant blow to its artificial intelligence ambitions. The tech giant is set to lose one of its most senior AI executives next month. Robby Walker, a key figure in Apple’s AI development, will be departing the company in October 2025.
This departure comes at a critical time. Apple has been struggling to keep pace with competitors in the rapidly evolving AI landscape. The company’s cautious approach to AI development has raised concerns among industry observers and investors alike.
The Man Behind Apple’s AI Efforts
Walker’s journey with Apple began in 2013. That’s when the Cupertino-based company acquired his startup, Cue. Since then, he has been instrumental in shaping Apple’s AI strategy. His role evolved significantly over the years.
Most recently, Walker served as senior director of Apple’s “Answers, Information and Knowledge” team. This position placed him at the heart of the company’s AI initiatives. He took on this role in April 2025, marking a transition from his previous responsibilities.
Before his current position, Walker was the man behind Siri. He led Apple’s voice assistant until earlier this year. However, his oversight of Siri came to an end when management shifted the responsibility to Craig Federighi, Apple’s software chief. This change wasn’t just a routine reshuffling. It came after promised improvements to Siri were publicly postponed.
The shift represented a high-profile setback for Walker. It also highlighted the challenges Apple has faced in advancing its AI capabilities. Siri, once considered groundbreaking, has struggled to keep up with newer AI assistants from competitors.
Apple’s AI Search Ambitions
After stepping away from Siri, Walker didn’t fade into the background. Instead, he took on another crucial project. He became one of the top executives working on Apple’s new AI-powered web search system. This ambitious project aims to compete directly with services like ChatGPT and Perplexity.
The search system represents Apple’s attempt to reduce its dependence on Google. Currently, Google pays Apple billions of dollars annually to be the default search engine on iPhones and other Apple devices. However, Apple’s own search technology could change this dynamic entirely.
The project is scheduled to debut in 2026. It’s designed to offer AI-powered search capabilities that could rival existing platforms. Walker’s departure raises questions about the timeline and execution of this critical initiative.
A Pattern of Departures
Walker’s exit isn’t happening in isolation. Apple has experienced a concerning pattern of AI talent departures in recent months. Several high-profile executives and researchers have left the company, many joining competitors.
Meta Platforms has been particularly successful in poaching Apple’s AI talent. Ruoming Pang, who headed Apple’s AI models team, recently joined Meta. Mark Lee and Tom Gunter, two other Apple AI researchers who worked closely with Pang, also made the move to Meta’s Superintelligence Labs division.
Frank Chu, another senior executive focused on search infrastructure, left Apple for Meta as well. These departures represent a significant brain drain for Apple’s AI division. The company is losing experienced professionals who understand both the technology and Apple’s internal processes.
The trend suggests deeper issues within Apple’s AI organization. Talented individuals are choosing to leave for competitors, potentially indicating dissatisfaction with Apple’s AI strategy or execution.
Leadership Changes and Internal Struggles

The departures have coincided with significant leadership changes within Apple’s AI division. Reports earlier this year suggested that CEO Tim Cook had lost confidence in AI chief John Giannandrea’s ability to execute on product development. As a result, oversight of Siri was reportedly shifted to Mike Rockwell, vice president of the Vision Products Group.
These internal reshufflings point to broader challenges within Apple’s AI efforts. The company appears to be struggling with both talent retention and effective leadership in this critical area. The frequent changes in responsibility and oversight suggest a lack of clear direction or confidence in the current approach.
Apple’s Cautious AI Approach Under Scrutiny
Apple’s measured approach to AI development has become a source of concern. While competitors have raced ahead with advanced AI models and features, Apple has been notably cautious. The company’s Apple Intelligence suite, which includes ChatGPT integration, has rolled out slowly compared to rival offerings.
This cautious approach extends to Siri as well. A major AI-powered upgrade to Apple’s voice assistant has been delayed until 2026. This delay is particularly significant given that competitors like Google have already launched advanced conversational AI features.
Google’s Gemini Live naturalistic chatbot has been operational for some time, while Apple’s equivalent remains in development. This gap highlights the challenge Apple faces in catching up to competitors who moved more aggressively into AI.
The company’s recent product launch event provided little clarity on its AI strategy. While Apple unveiled new iPhone models, including the slimmer iPhone Air, there was minimal discussion of how the company plans to compete with Google’s Gemini AI technology and other advanced AI systems.
Industry Context and Competitive Pressure
Apple’s AI struggles are occurring against a backdrop of intense industry competition. Companies like Google, Microsoft, and OpenAI have made significant strides in AI development. They’ve launched products that have captured public attention and demonstrated clear competitive advantages.
Google, in particular, has integrated its Gemini AI technology deeply into its latest devices. The company has showcased impressive capabilities that highlight the potential of AI-powered features. Microsoft’s partnership with OpenAI has also yielded significant results, with AI features integrated across its product portfolio.
Meanwhile, Apple appears to be playing catch-up. The company’s traditionally secretive approach to product development may be working against it in the fast-moving AI space. While secrecy has served Apple well in other product categories, AI development benefits from rapid iteration and public feedback.
Financial and Strategic Implications
The talent exodus and delayed AI initiatives have potential financial implications for Apple. The company’s stock performance and investor confidence could be affected if AI capabilities become a significant differentiator in consumer technology.
Apple’s relationship with Google also adds complexity to the situation. The billions of dollars Google pays to be the default search engine on Apple devices represent a significant revenue stream. However, if Apple successfully develops its own AI-powered search technology, this relationship could change dramatically.
The development of Apple’s own search capabilities could reduce its dependence on Google while potentially opening new revenue opportunities. However, the departure of key executives like Walker raises questions about the company’s ability to execute on these ambitious plans.
Looking Ahead: Challenges and Opportunities
Walker’s departure represents both a challenge and an opportunity for Apple. The company will need to find suitable replacements for the departing talent while also addressing the underlying issues that may be driving these exits.
Apple’s substantial financial resources provide it with options for addressing these challenges. The company could potentially acquire AI startups or talent to bolster its capabilities. It could also increase investment in AI research and development to accelerate its progress.
However, money alone may not solve Apple’s AI challenges. The company needs to develop a clear, compelling AI strategy that can attract and retain top talent. It also needs to demonstrate progress in delivering AI features that match or exceed competitor offerings.
The 2026 timeline for Apple’s AI-powered search system will be a critical test. Success could validate Apple’s approach and demonstrate its ability to compete in AI. Failure could further highlight the company’s struggles in this crucial technology area.
The Broader AI Talent War

Walker’s move is part of a broader talent war in the AI industry. Companies are competing aggressively for experienced AI professionals, driving up salaries and creating opportunities for career advancement. This competitive environment makes it challenging for any single company to retain all its top talent.
Meta’s success in attracting Apple’s AI talent suggests the company is offering compelling opportunities for these professionals. Whether through higher compensation, more interesting projects, or better resources, Meta appears to be winning the battle for Apple’s AI expertise.
This talent competition is likely to continue as AI becomes increasingly important across all technology sectors. Companies that can’t offer competitive packages or compelling work environments may continue to lose talent to more aggressive competitors.
Conclusion: A Critical Juncture for Apple
Robby Walker’s departure marks a critical juncture for Apple’s AI ambitions. The company faces significant challenges in retaining talent, executing on AI initiatives, and competing with more aggressive rivals. The pattern of departures suggests deeper issues that go beyond individual career decisions.
Apple’s response to these challenges will be crucial for its future competitiveness. The company needs to demonstrate that it can successfully develop and deploy AI technologies that match or exceed competitor offerings. It also needs to create an environment that attracts and retains top AI talent.
The stakes are high. AI is rapidly becoming a fundamental technology that influences everything from search and voice assistants to autonomous vehicles and healthcare. Companies that fall behind in AI development risk losing relevance in key market segments.
For Apple, the departure of executives like Walker represents both a warning and an opportunity. The company can use this moment to reassess its AI strategy, address internal challenges, and recommit to competing effectively in this crucial technology area. The question is whether Apple will rise to meet this challenge or continue to struggle with AI execution and talent retention.
