Ya know one thing I will be very sad about is that current generations and future ones will never experience the friday night movie rental+sleepover planning + pizza ordering + all that . I wasn't even a popular kid in school and I would always find friends and their families at the rental store on fridays and we'd compare notes/movies/etc, sometimes set up impromptu sleepovers, and go home with three, four, or five movies (and maybe a video game!) and a few boxes of candy and soda. And also make a call from (or in our case, go next door to the pizza hut and get a take away order going.)
I get in the modern time we have phones that can literally do all that , including discord streaming movies with friends from across the country and instant getting first run movies streamed to us and pizzas and all that hand delivered by gig workers... but it feels so souless and empty compared to what it was.
