It seems a little short-sighted to destroy an artifact to get the text.
Perhaps the genetic material that remains in books from the people who handled them, or the pollen from plants in the environment that the book existed in will have value in the future, but we won't know what we lost because some people foolishly destroyed it in a bizarre quest to make AGI that the creators argue could potentially destroy humanity.
The more and more I read about these kinds of people the more I'm starting to realize that they're in the "here for a good time not a long time" group of people and those are the last people you want making long-term decisions.
