Brain2 vs the Classic File System and Notes Concept

We've been using the concept 'file system' for so long, it's time to change. In this AI-powered era, OSes should function on a new concept called Brain2 instead of File System.

Brain2 is a data system which is based on graph, graph of trees or structures, including separate nodes can be in the graph too. 

The old file system concept is about storing files in a tree, and all other data are on that tree, including files to serve the databases.

The new concept is that file system concept is replaced by a graph-based database at core and it is already a database without functioning on top of files.

Visually when using apps on such Brain2, user will see notes and graph of notes first instead of files first then notes as a type of files.
