Siri’s originators still chase a 'do engine' as Apple unveils AI-powered assistant
Siri’s co-founders Dag Kittlaus and Adam Cheyer say their long-held vision of a universal 'do engine'—an AI that handles tasks across apps rather than just web search—persists as Apple rolls out a rewritten Siri AI in iOS 27 that can analyze on‑screen content, operate apps, and leverage data from calendars and messages, all while emphasizing privacy via Private Cloud Compute. Apple aims to outpace rivals like OpenAI’s ChatGPT and Google’s Gemini. While the founders note Apple’s focus on its own products and privacy could give Siri an edge, the fully realized 'do engine' remains elusive, and a shift toward AI assistants could reshape how people interact with apps and business models across the ecosystem.
