Apple is preparing for its yearly Worldwide Developers Conference because there are growing concerns about its ability to innovate and keep up in the competition for artificial intelligence (AI). This year's event is expected to be less exciting than previous ones, focusing on a major update to its software, including a new look for iPhone's standard apps and a new system for naming its operating system updates. Despite some delays in making Siri's AI features better, Apple remains positive about how it is doing. However, as Apple tries to solve its AI problems, rivals like Google and Samsung are adding more AI to their products, which is increasing the difference between them. Additionally, new government rules and trade war uncertainties are a concern for Apple, potentially affecting its earnings and how it manufactures products. These issues have led to Apple's stock price falling by almost 20% this year, making it the third most valuable company globally, after Microsoft and AI chipmaker Nvidia.
