I go through a ridiculous number of Audible books. (I know, I know, Amazon is evil, and I'm trying to transition to libro.fm - but it's hard to resist those huge sales.)
For the first time, I believe I bought an AI-generated book. Mad at myself and mad at Audible/Amazon.
The book description is an overhyped sales pitch. The reviews - all 5 stars - are all from people who received the book for free. Yet there are zero reviews on GoodReads. The book itself is a meaningless murmur of vague phrases. No personal stories, no concrete dates or places, nothing to actually learn and apply. The author has no web presence whatsoever, despite having published 30 books on Audible. The fact that some of those books are on developing psychic powers or creating LLCs makes me doubt their credibility and motives.
Sadly, Audible doesn't care if books are AI generated.
