If you cut up the book into paragraphs, sentences, and phrases, and rearranged them to make and sell your own books, then you are likely to fail each of the four tests.

Ah, the “collage machine” description of how generative AI supposedly works.

It doesn’t.

But even if you manage to cut those pieces up so fine that you can’t necessarily tell where they come from in the source material, there is enough contained in the output that it is clearly drawing directly on source material.

If you can’t tell where they “came from” then you can’t prove that they’re copied. If you can’t prove they’re copied you can’t win a copyright lawsuit in a court of law.
