That’s a good example for showing how “UI” and “UX” are essentially the same thing. At least in a practical context.

We can call an excellent story teller a “writer”. A good story can be described as “good writing”. A great story, let’s say a film being adapted as a book, can become a terrible book if it is “let down by the writing”.

In the context of books and storytelling, “writing” is the all-encompassing word that experts use to describe the whole thing. Just like “UI” used to mean the whole thing.
