In Google's vision of the future, your computer is a thin client. There is no My Documents folder, as everything personal lives on gdrive. The Chrome app store becomes the new operating system. Apps will have access to your files, they will be able to search them, open them, and operate on them. You will never see the "Open file" dialog box again.
In this world, the concept of a file on your local computer in some folder does not exist. Your stuff is simply available to you from the cloud from whatever computer. The abstraction or concept of a "file" or "folder" will fade. Our children will not know what these words mean. They will see their pictures in a web interface with location and time overlayed, completely oblivious to the fact that it happens to be stored as a .jpg file somewhere on google servers and an associated .txt file that contains some meta data about it.
We are finally moving beyond (arbitrary) abstractions from mid 1900's. I like this future.
