I think I'd argue that the people whose emails can be sufficiently answered with an LLM are the ones whose jobs are first on the chopping block, so the product has a self-destructing user base.
Not necessarily. When I was writing the initial comment I wasn't even thinking about job-related mails, but at someone like Sean Carroll who does a regular Ask me Anything [1] where lots of questions are skipped for lack of time, or in general academics who receive plenty of emails about articles and various field-related questions.
