They just expected us to know how to use them.
And they still do. The "kids these days and their compyooturs" fallacy. Irks me to my core.
I was fortunate to have a middle school typing and graphic design class, and in highschool I learned hardware troubleshooting and stuff (A+ equivalent IT work)...but that "career path" of flipping computers that people downloaded the wrong screensaver on kinda died out.
Still learned a lot though! If the I.T field was still hanging out with buddies in some dungeon nobody visited, I might be in that field today lol.
