I mean, I can't stop people from emailing me. I get over a hundred non-spam, non-mailing-list emails on some days. I'm not able to respond to most of them. I'm often not expected to, I'm just being copied in as a FYI. The AI is able to assess subject and intent well enough to determine what should receive my limited time, and through the voice interface it converts "making coffee" time into "composing email" time. I do read every email that's sent to me eventually, but it can take several weeks in some cases. I don't let AI reply to anything for me, but I'm happy to have it propose a draft.
