I had to look up Plan 9, and in doing so, I found that "Everything is a
file" has its own wikipedia page. It says, "But file descriptors are also
created for things like anonymous pipes and network sockets via different
methods. Therefore a more accurate description of this feature is
Everything is a file descriptor."

And the page for File descriptor says, "In Unix-like systems, file
descriptors can refer to any Unix file type named in a file system. As
well as regular files, this includes directories, block and character
devices (also called "special files")"
