>Instead ebook readers came along and reinvented filesystems, because users cannot be trusted to organize their book collection themselves.

In the early days of Mac OSX, iTunes actually did a great job of just organizing your music collection for you. It would sort your music into a nested hierarchy by artist, album, and track title based on the metadata on the file, which you could edit with iTunes. When you changed stuff around it would actually modify where the files were saved in the library folder.

It worked great. It was structured logically in your iTunes library, but organizing and tagging your iTunes library also wound up structuring your file system logically automatically. So there was never this sense of a pretty veneer over a messy clusterfuck underneath. The whole thing is designed to keep things tidy and organized.
