John Ternus Takes Apple's Top Job as AI Race Intensifies

John Ternus has officially begun his tenure as Apple's chief executive, taking the reins from Tim Cook and stepping into one of the most scrutinised leadership roles in the technology industry.

Ternus, who built his reputation at Apple overseeing hardware engineering — the division responsible for iPhone, Mac and iPad development — now faces the immediate challenge of steering the Cupertino giant through an increasingly competitive artificial intelligence landscape.

The transition marks the end of a defining era. Cook, who succeeded the late Steve Jobs in 2011, presided over Apple's growth into the world's most valuable company, expanding its services business and cementing its ecosystem of devices. Ternus inherits a business generating hundreds of billions in annual revenue but under growing scrutiny over whether Apple is moving fast enough on AI.

Rivals including Google, Microsoft and a wave of AI-native companies have aggressively pushed large language models and AI-powered features into their products. Apple has responded with Apple Intelligence — its suite of on-device AI tools — but analysts and investors have questioned whether the company's cautious, privacy-first approach is costing it ground in the AI race.

Ternus is widely respected internally for his engineering rigour and product instincts, qualities that those close to the company say make him well-suited to drive the next generation of Apple hardware with AI baked in at the chip level. Apple's custom silicon, developed under his watch, has given the company a significant advantage in running AI workloads locally without relying on cloud infrastructure.

His first days in the role are expected to signal how Apple plans to balance its trademark premium positioning with the need to ship AI features that can compete with what Google's Gemini and Microsoft's Copilot already offer consumers daily.

The leadership handover also comes as Apple navigates regulatory pressure in Europe and the United States, ongoing supply chain tensions, and questions about the long-term growth trajectory of the iPhone — still the engine of Apple's revenue despite the company's push into services, wearables and spatial computing.

For employees, investors and the broader technology industry, Ternus's opening moves will be watched closely. A CEO transition at Apple happens rarely, and the weight of expectation — to innovate, to maintain margins, and to win the AI era without compromising the qualities that built the brand — lands squarely on his desk from day one.
