However, IMO comparing SharePoint to Google Drive is apples and oranges (and really OneDrive consumer is the appropriate comparison) SharePoint uses metadata and a content type model to organize everything, which is indexed so it can be searched on and have custom filters, views, and forms built off of it. It's a double edged sword though in that as much as it helps organize lots of documents, it also has a lot of maintenance overhead (and a lot of special nuances that people need to learn). It also supports a lot of features that are aimed at implementing simple business processes like workflows, versioning, and document templates.
More recent updates have been trying to gloss over a lot of the complexity and simplify the UI, to make it look more like a consumer level product I guess.
