It's the thing with abstractions: changing angle changes the abstraction by seemingly replacement candidates, but only the good ones maps properly onto physical hardware and human cognition.

eg: "everything is a file" maps properly to both physical storage with addressable, streamable content and to the human mind as data reachable by classification (file name). Maybe a revolutionary OS design could better that with "everything is a message", but I think you can understand why one can have doubt on this translation from files.
