The idea behind the author's post is that a directed acyclic graph is a basic block that is just one layer of abstraction above raw bytes. JSON, YAML, TOML, INI, .properties, environment variables are all just different ways to represent a graph and if it were possible to store the graph directly in the filesystem then one would not have to manually [0] serialize the graph to bytes and deserialize it back later.

[0] graph -> byte conversion is the job of the graph filesystem
