Here's a product (Gmail/Outlook add-on or so): have your own LLM trained over your public texts (articles, books, blog entries, READMEs, Hacker News comments, and so on), mark the emails you can't respond to with the "GPT" label which puts the mail in a queue and if you don't remove the label in 7 days or so, it sends a response with a polite intro "I didn't have the time to get to your email, but here's what I might think as a response".
Good thing that with the coming devastating job purges due to statistical learning such "careers" based around bullshit jobs [1] where some words in a generated email can be "career-terminating" will be forever gone.
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.
