I'm really buffled what makes it for Apple so difficult to cut off Siri and replace it with state-of-art technology (LLMs). Siri is still akin to a "dumbphone" 4 years into the age of "smartphones" which is a good indicator for a lost case and when it's better to start a product from scratch without the tech debt.
Me: Hey Sir, set a timer for my management meeting in 10 minutes.
Siri: I've deleted your minutes from the last 10 management meetings.
