The problem with Siri is not the lack of LLM level functionality, but rather a lack of programming Siri to do obvious things that users would expect it to do. Well, that, and worst in class speech recognition. They are one of the top valued megacorps in the world and they can't hire a product manager who understands basic UX??? My retired ass could write a fairly comprehensive set of user stories for Siri in a couple weeks.
