Email is still really useful when you have a lot to say but don’t want to write a letter. If I’m catching up on the last several weeks with my parents, I’m not going to write a 10-page text. I can write a nicely formatted email and attach a few photos, though. It’s far more convenient than writing a letter and stuffing a bunch of printed photos into an envelope.
I’ll start: 39/M/US, so yeah, I fit the demographic.
I have never really considered Lemmy or Reddit to be “social media.” They’re entirely anonymous, and you’re not being exposed to posts where a apecific person is talking about themselves (at least for the most part). I think a modern equivalent to a PhpBB forum or (if you’re old) a BBS is more accurate.
It’s actually surprising how much just having a person in the room can alter the temperature and humidity levels. In my master bathroom, I have my bathroom fan set to activate when the dew point reaches a certain level (I’ve found that dew point produces better results than just humidity); the idea is that the bathroom will be ventilated when someone takes a shower and for however long it takes for the humidity to dissipate after they’re done. The funny thing is that every so often, I’ll take an excessively long poop (lets me honest, I’m scrolling on my phone), and the fan will kick on. Just being in the bathroom will alter the dew point enough that it triggers the fan.
I also have a room that contains all my server/networking equipment. It’s climate-controlled, and I’m constantly monitoring temperatures. The times that in the room working, I can see a noticeable spike in the temperature graph, even though the only variable that’s changed is that there’s a person in the room.
So my point is: OP might not have been having fun that night; it’s entirely possible someone just came in and went to bed.
If these jobs become automated, that doesn’t automatically create more “high level” jobs. It just creates unemployment.
