imagine how shitty it would be to use a computer where you can't access the file system. explorer or finder or whatever you use doesn't exist. you can't browse your documents folder, in fact, there isn't one. word documents are stored "in word", and other apps can't access them unless you press a "share" button.

welcome to iOS! the future of mobile operating systems involves the deprecation of the file system. the file system is a messy thing -- users can delete critical files, lose documents, make a mess of symlinks... why should we let them? why teach them not to when you can just prohibit them from doing it entirely?

on android, accessing the file system is a pain in the ass, and when you get there, it's an absolute mess. files are stored five directories deep in weird, unintuitive directories. the internal storage is at /sdcard, and your SD card is /storage/6437-2347. encrypted files are strewn about directories like /sdcard/Android/obb/com.company.appname. it's horrible.

on iOS, it's even worse -- you can't access the file system at all.

this is the way we're heading. the concept of the file system is being abstracted away. it's dying. sure, it'll never disappear -- of course it won't. the unix based operating systems will never do this. windows might. macOS probably will. but that's a good thing, right? you don't want to hurt yourself, do you?
