During the 2025 Worldwide Developers Conference (WWDC), Apple unveiled updates to its iOS 26 and iPadOS 26 operating systems, along with a novel design technology dubbed "Liquid Glass." However, the much-anticipated enhancement of Siri, aiming to make the virtual assistant more personalized and AI-driven, has been rescheduled to within the following year. This announcement resulted in a 1.21% decline in Apple's share price on the day. Analysts speculate that the delay in Siri's upgrade could be attributed to technical hurdles or strategic shifts, particularly as the Android system has secured a substantial lead in the realm of generative AI.
