Teaching advanced IT topics like programming or system management has become much harder in only about five years, because many 20 year olds do not know how to effectively work with the file system. I don't blame them: the Microsoft Office applications nudge you strongly towards storing everything in the Cloud (saving files locally requires extra clicks), and on Windows, the folders C:\Users and C:\ are almost hidden in he respective dialogs (open file, save file). Same on macOS. Students also keep loosing files. This used to be an excuse for not doing the work; nowadays, you're able to find the files on their systems by using appropriate tools (e.g. `find`, installed with Git Bash on Windows). And don't get me started on touch-typing... hell, those kids were fast ten years ago with a proper keyboard! Now they're fast with their smartphone, but painstakingly slow on an actual keyboard.
