Apple is restructuring its AI leadership, moving Siri under the direction of Mike Rockwell as part of an effort to revive the underperforming voice assistant. John Giannandrea, who previously led Apple's AI division, struggled to translate investment into successful Siri enhancements. This transition is seen as part of a broader strategy to integrate AI capabilities into Siri, despite criticism regarding its persistent ineffectiveness and the challenges of voice user interfaces. Many commentators express skepticism about these changes, citing a lack of urgency in addressing Siri's failings and calling for a deeper introspection within Apple’s organizational structure to balance decision-making with execution. There is hope, however, that leveraging modern technologies and development paradigms could lead to significant improvements in Siri's functionality.
