Hobby: I'm trying to write a simulator for Brandon Sanderson's cosmere magic system using a vector database to represent the in-universe spiritual realm and all it's connections, and small AI models to represent intents.
Not all authors are against this either. Some big names are all in supporting Spotify (and other new audiobook platforms) because they are sick of Amazon/Audible monopoly.
Personally though, Spotify's audiobook user experience is paltry compared to a dedicated app.
