Two years ago, at Apple’s Worldwide Developers Conference 2024 (WWDC), a representative presented an astonishing demo. “Siri, when is my mom’s flight landing?” she said. In a blink, Siri found the flight details in an email from her mom, checked the flight’s progress online, and displayed the updated landing time. Never once did the rep open the Mail, Messages, or Maps apps, go online, or search for anything. This was beyond ChatGPT; it was AI as your agent.
