Amazon had an insane number of people working on just the alarms feature in Alexa when they interviewed me for a position years ago. They had entire teams devoted to the tiniest edge case within the realm of scheduling things with Alexa. This is no doubt one of the biggest use cases in computing: getting your computer to tell you what to do at a given time.
Apple has not innovated in years and a GPT Phone where your lock screen is a FaceTime call like UI/UX with your AI Agent who does everything for you would give Apple a run for it's money! Pick up your phone & see your agent waiting to assist & it could be skinned to look like a deceased loved one (mom still guiding your through life).
To get things done it would interface with other AI Agents of businesses, companies, your doctor, friends & family to schedule things & used as a knowledgebase.
Maybe this is their step towards creating said agents?
