Arthur, Captain of the Ship of Theseus

Arthur was an award-winning freelance writer.
Studios would call him in to write scripts for shows and movies.
And he would. He’d sit down at his typewriter and bang out something and hand it in.
The executive producer would look it over, cut Arthur a check, and thank him.
A few weeks or months later, Arthur would catch whatever movie or episode he’d worked on.
It was nothing like what he’d written.
Every scene, every line of dialogue changed.
At first, he felt insulted.
But over time, he learned not to care.
Collected his wits, his checks, and his awards.
