• Even with millennials, I feel like there’s a big chunk who still barely have any understanding. At least I assume most know a file system exists (ie know of folders and such), but most would think it’s synonymous with the gui software they use to explore it and would have no idea how to even start navigating it by command-line or even imagine it’s possible to using an alternative interface to the one that came with the OS. Whereas younger gens that grew up on iPhones that hide the file system would have no clue. And the older generations frequently just used the desktop for everything.
