I still remember getting in trouble at my public school with the IT admin because my friends and I discovered how to write BAT files, and had the brilliant idea to create a bunch of fork bombs that self-replicated until they froze their host computer.
Unfortunately I think kids today don’t even get enough leeway to figure that sort of shit out. But kids are awfully good at finding cracks in systems, so maybe they’ve just figured out how to get up to similar hijinks with GUIs and cloud storage.
