I'm honestly baffled at this either revelation or a meme, being reposted over past few years, about modern teenagers unable to recognize or use some tech predating them. I was born around 90s and never had to use for example a typewriter or punch-cards or 8" diskettes, but I could recognize all that stuff without any training since my childhood. Same with most other gadgets from before my generation. How come kids are supposedly can't recognize a rotary phone for example? Or an analog clock?
