The folder concept was already outdated when it was conceived. First, unlike the physical world, we don't have to have one place for things (e.g. a sock drawer). We can have separate ways to access the same thing. If you think about it, tags/labels are just folders, but so that you can place the same thing in multiple folders. But more, the future is to have a fast expanse of metadata, most of it computer generated, and access content based on queries of that.
