An interesting take and I would like to have the faith that the writer has at humans giving preference to human artists inherently.

My concern would be that should these writing bots become 'good enough' where the development and consistency is at least passible, then the fact that the costs of creating it are so negligable becomes a real factor.

If a book by an AI vs a real author, particularly in the fiction realm where facts don't matter, are not wildly distinguishable but one is produced for a fraction of the cost, it has to have some impact.

This only points to a possibility that people are threatened by the use of AI. I've read this article before. It doesn't explain everything I need to know about this.
