This is an older story, but I installed Xubuntu on an ssd in my boomer parents Vista era computer to keep it running. They really didnt know the difference, my mom only played solitaire while Thunderbird was managable for my dad. My millenial neice and nephews had no idea either, I'd find exe files they would download, but noone ever said anything about why they didnt work anymore. They have no idea about how computers work.
I'm not very technical, but I had to move a jumper on my old 386 when I upgraded my modem.
