(to be frank, nor do they seem to need it, as everything is so polished these days)
The problem is if you don't know basic concepts of computers you cannot transfer your knowledge from one program to the next. Folder structures are a bizarre thing for many people and if they see one in program A, then they won't understand that in program B it works the same way.
I have never had any issues learning any new software from scratch, but I see people my age not figuring out where to click next or where something they are looking for might be hidden in the options. Then an update comes that changes things and they are back to square 1 and helpless.
