On the other hand, your book gains value by being published in 2021, i.e. before ChatGPT. Is there already a nice term for "this was published before the slop flood gates opened"? There should be.
(I was recently looking for a cookbook, and intentionally avoided books published in the last few years because of this. I figured that the genre is a too easy target for AI slop. But that not even Springer is safe anymore is indeed very disappointing.)
Good one!
