I think this article is (doing a bad job of) attempting to explain that limitations behind the current byte-stream oriented interfaces and hierarchical organizations that have been around for 20 years. These two limitations show their heads when 1) people want extreme speed (parallel I/O), and 2) file systems begin to contain billions of files. People are storing more and more structured data, and building enormous middleware layers on top of the read/write to only present richer interfaces to higher levels.
