When I was in school they had Apple II's and pretended using LOGO was learning how to use a computer. Chromebooks are closer to real world computer usage than we've typically had, barring whatever ten-to-fifteen year period where school computers were Windows PCs, which may or may not have happened at all depending on where you live.
The loss of literacy has way more to do with moving from old CLI-based OSs and to GUI OSs and eventually phone and tablet OSs. Not that I'd want to go back to MS-DOS, but the only reason anybody had any understanding of where every part of the OS went and what it did is having to navigate it from memory and it being built from two sticks and three rocks.
