I hope this article itself is a very subtle April Fools joke because it’s literally just the Facebook boomer “kids today don’t recognize this” meme, and it’s just as dumb. Maybe if we’re talking about literal children, but even if you’ve never used a floppy disk before, you’ll have seen them referenced in various forms of media. There’s lots of obsolete technology that I recognize despite never having used it. And even if you don’t recognize a 3.5” floppy on sight, you can infer that this is physical media and understand the joke.
