Apple has announced a major overhaul of Siri, and analysts say that if the revamp is successfully completed by the end of the year, Apple will have a significant chance to rival its long-time rival Google's Gemini assistant. Investors have largely forgiven Apple's "lagging" in generative AI, and a key challenge for new Apple CEO Benjamin Turner is convincing users that Apple devices are the best way to use AI. Carolina Milanesi of Creative Strategies said that if Siri remains poor, Turner's Wednesday will be "much sadder." Now they can confidently say that Siri is working and has value, but they need to continue working to make it better and keep up. Analysts say that Turner, who has kept a low profile for five years as head of hardware engineering, will likely focus on providing powerful devices to lay the foundation for the expansion of on-device AI. However, he faces significant regulatory challenges. Gene Munster of Deepwater Asset Management said that Apple's Siri will not initially launch in Europe due to regulatory disputes. A timely launch of the new Siri in the US is crucial, as it will build confidence that they can also succeed in Europe.
