"Give overly-eager chatbot control over your personal email" probably has so many failure modes, we haven't even thought of one tenth of them yet. We've got a few years of this ahead of us. Pass the popcorn.
(I see a RomCom script where the chatbot decides to get two people together, and acts as Cyrano de Bergerac for the handsome-but-lunkheaded farmboy, and bestie/confidant for the girl-about-town).
