A lot of the decaying skills are things like understanding your computer's file system (i.e. how folders and files work, where they are, etc.) This kind of skill is definitely still needed if you work in an office environment. It may not be necessary if all you're doing is being spoon-fed Instagram posts on your phone, but understanding where you saved your files is pretty damn important for most office workers' day to day jobs (especially with how dogshit Windows' search functionality is).
