As is sometimes the case, I 'half-agree' with you 😇
I miss QSL cards also. It was an intrinsic part of the hobby as I was growing up and remember, I've been on the air, in some form or another since the early 1960s. But I do understand why the attraction of QSL cards, whether printed or electronic, has faded away. When was the last time I received an actual letter, other than Christmas cards? Heck, I don't think I've received a birthday card in a decade. Everything is either via email, SMS or, in my case, an online forum. Again, I miss the good ol' postal connection, but I understand it. It's not so much, in my opinion, that people are lazy or worried about the postage. I would argue that it's simply a matter of now-adopted habits.
Also, not sure I would agree that people are cheap b...rds. I know I'm not. But again, when was the last time I actually sent a letter, never mind receiving one. I honestly, truly cannot remember. It might have been to my mom before she passed in 2006, maybe. Otherwise, it might actually date back to the 90s.
I'll conclude by saying that for us old-timers, QSL cards were magical. I miss them, but I understand why they have lost their luster.
