On Monday, Tim Cook walked on stage for the last time as Apple CEO, receiving a standing ovation from thousands of Apple employees and developers. He announced a complete overhaul of its AI assistant, Siri, acknowledging that Apple had fallen behind. Craig Federighi, Apple's senior vice president of Software Engineering, admitted Apple had been doing AI wrong, stating, "We believe that truly helpful AI must be centered around you and your needs," and leveled a critique of "AI for the sake of AI without considering the people it's supposed to be able to serve." The new Siri will have its own app, work across Apple products, draw from personal data, and do so while "keeping privacy in mind at every step."
