My personal hot take: Folders are just heirarchical tags. Tags are just non-heirarchical folders. Both can be compared to programming classes, with subclassing representing folders (key negative: Can't inherit from multiple parents), and class composition representing tags (key negative: No heirarchy). Folder names (including parent folders) could automatically be applied as tags. Tags could likewise be viewed as folders (tags with multiple "parents" would be something like symlinks), but would need a heirarchy to become nested.
