And on top of that, we've all seen how confidently LLM's get things wrong. I've seen them get better, but even the current SOTA models fumble. Why would you want to send a bot a message "sure, reschedule my flight" and have a bot potentially fumble that in all sorts of ways? I really really do not see the appeal. My calendar and my emails and my things to do are all things I want to be on top of. Not have it half-assed or potentially messed up by a chatbot made to harvest all your data.
