Amazon and Goodreads must take steps to combat the flood of AI-generated content that will mislead readers and damage author reputations.
It might help to imagine it as if it were a different product. Imagine if you went into a shop to buy a computer and there were thousands of different computers for sale. Some of them made by actual people and some made by AI. The shop doesn’t test these computers so you might buy one that doesn’t work, or is missing a vital component, or is just a case full of sand. Each one has reviews but they’re all rated 5 stars with AI generated review text. What do you buy?

You can stop at this point, I wouldn’t go to such a shop. Most people wouldn’t.
