An all-TTS audiobook offering is just about as appealing as an all-stable-diffusion picture gallery (that is, not at all).

Isn’t it more like an art gallery of prints of paintings? The primary art is the text of the book (like the painting in the gallery), TTS (and printing a copy) are just methods of making the art available.

I think it can be argued that audiobook's add to the art by adding tone and inflection by the reader.

To me, what you're saying is the same as saying the art of a movie is in the script, the video is just the method of making it available. And I don't think that's a valid take

There already are audiobooks on audible that are 100% TTS, while it's playable, it's no substitute (yet) for a real human.

It's just too flat/dead compared to a human reader.
