My prediction is that Amazon will soon use Claude's Watermark to Auto Flag AI Books with a Badge
Recently Anthropic announced that Claude will watermark generated text. I actually predicted this a few years ago. My theory at the time was that a way for an AI company to watermark generated content was to introduce a statistical pattern. For example, if an LLM has the choice of using word 1 or word 2 for the next word to complete the sentence they will go with word 2 in every other case or so to create a statistical pattern. That's just an example. But the end user will not be able to detect the watermark.
Some of this happening due to EU laws so there is a future where most AI use would be watermarked.
If that's the case, my next prediction is that Amazon will auto flag self-published books in some public facing manner with a badge, and even those traditionally published as generated / assisted by AI or not. The same sort of thing that YouTube currently does with AI content.
