I wouldn’t mind one triaging my email, voice mail can calls.

Yesterday I just tested a stream of conscious rambling paragraph of things I need to do with chat GPT, then asked it to extract tasks, infer importance and interdependencies, and then enumerate a list of them. It had even grouped related things together, but I asked it to separate them, and it did. I really want to wire this up to Apple reminders.

Gmail has had the "important" flag for ages, and that's done automatically. The issue is training the AI to work for your data (e.g. I find Gmail still hasn't picked up the differences in spam I get, and so some specific spam still going to my inbox, and some specific ham ends up in spam).

Unfortunately, just because one provider provides a good AI, doesn't mean others will (and in a work context, you may be stuck with the bad one).

GPT-3 has the API available for those who want it, and it can do fine tuning, so for OP's specific use case it feels like the only limit is the size of one's wallet.

That's may be because the social IQ of current tech is essentially zero. It'll be a lot less annoying (but also a lot more insidiously dangerous) once it's smarter.
