Meanwhile every time this subject comes up (and cascades into side topic posts about how it is hard to self host and mutt vs thunderbird) I'm left wondering why we even need internet mail anymore when there are so many other overlapping communication channels already.
You message your normal friends on WhatsApp.
You message your nerdy friends on Signal.
You message your drug dealer on Telegram.
Nobody writes email sized messages anymore just like nobody writes letters anymore.
You message your in-laws from an incognito Facebook tab a couple times a year.
Sometimes when you want to message no one in particular you shout into the void on Twitter.
You communicate with your team by hooking up GPT-3/perl-script to your corporate slack for your first gig and Microsoft Teams for the secret second gig. Just be sure to not send the emojis after work hours.
That open source project you like is now increasingly sequestered on some discord instead of a traditional mailing list.
What is left for internet mail to do? Seems like it mirrors the real life postal service and has been reduced to mostly junk mail and newsletters you aren't going to get around to reading because you're busy slogging through your RSS feeds (what is dead may never die).
Maybe we've been so obsessed with figuring out how to operate our own postal service like in the frontier days we forgot to ask ourselves whether we should want to in the first place.
Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift delivery of plain text messages over an open protocol via the public net. For What?
