The File Completeness Conjecture

Unix philosophy claims "everything is a file" until you actually try to cat a directory and get slapped with that condescending "Is a directory" error. Ten years into my career and I'm still occasionally typing cat on directories like some junior dev who hasn't been properly traumatized yet. The lie detector determined: that "everything is a file" was a lie. Directories, sockets, pipes—all just teasing us with their file-like appearances while secretly being special snowflakes.
