Apple Faces Siri AI Upgrade Bugs, Investor Concerns Ahead WWDC 2025

Apple is facing significant challenges in upgrading its Siri voice assistant with advanced artificial intelligence, particularly large language models (LLMs), ahead of its Worldwide Developer Conference (WWDC). Insiders and former executives reveal that Apple’s approach of retrofitting Siri's legacy system rather than rebuilding it from scratch has resulted in persistent bugs and delays, unlike competitors such as OpenAI and Google who developed AI assistants anew. These difficulties have dampened investor confidence, contributing to a notable decline in Apple’s stock, with expectations low for major AI announcements at this year's WWDC. Additionally, regulatory issues in China are further delaying the rollout of AI features powered by Alibaba’s models, exacerbating the challenges. The setbacks in Siri’s upgrade highlight broader concerns about Apple’s ability to innovate effectively in AI, a critical area for its future hardware and ecosystem growth. Despite the hype surrounding other software updates at WWDC, the unresolved Siri issues remain a significant obstacle for the company’s AI ambitions.
