As far as I can tell from listening to stories from friends who aren't in tech circles, sorta halfway knowing how to use a computer still makes you a wizard in most non-tech offices. And the newer generations are only barely better than the old ones, on average, so
that's not putting an end to that state of things.
I'm talking, like, you understand how external drives are represented, know how to cut & paste files & kinda know what a filesystem is and how it's laid out (not what a FAT table is or anything like that, I mean just how folders and links/shortcuts practically work and such). If you can do more than basic arithmetic in Excel, you're basically god. If you can write batch scripts (like this person, assuming it's true) or a little glue-code python, that's beyond what the others around you could even imagine.
I'm not sure whether this is a UX failure or there's just too much necessary complexity to make things better. To some degree I think the basic metaphors we use for representing computer concepts and UI to ordinary users are badly underdeveloped, or in some way misguided. Certainly I think the "iOS is dumbing things down and making people unable to compute!" folks have things exactly backwards.
