i just came across the AI researcher [specializing in critical thinking and the importance of humanity in the age of AI] who has talked about this at length (wanted to share the other day but couldn't remember her name. She's got a substack, youtube, etc but I only have accessed her instagram content.

this is an instagram post, the comments are really much more informative than the actual post because they get right into the discussion about the books.

and also
https://www.instagram.com/p/DbYBT3AshmI/, where they discuss this happening as early as 2023 (we're only hearing about it now) and some reasons why.
I agree with her general takeaway: the big overarching challenge is that DO books need to be digitized, but for everyone's use. Gutemberg and academic collections. A book that is rotting in a private collection or never gets accessed on a stack is not going to be of use to humanity. The more that get scanned and put into a publically accessible format, the better. Supporting libraries and researchers who are doing this work makes sure it stays in the public domain.
