So, I know it's an old take to laugh at people that don't know x that older people took for granted. The idea here was rather to give it a more respectful spin. Nobody's ridiculed here. It's supposed to give it this point of view of the older guy that doesn't make fun of the younger ones but just reminds them that they'll be in the same shoes eventually, with stuff that they took for granted fading into obscurity. You know, taking a more humble stance, without being condescending.
On another note, the save icon going away might have something to do with programs just writing everything to storage anytime ASAP so the whole idea of writing to disk just disappears. Don't know if I like that workflow though, I'm too used to saving my work.
