I don't see how building such a model of historical documents would impact authors (which most of them are dead anyways).
Then change the law. For everyone, consistently, not just massive AI companies. Until then, deal with it.

It impacts the authors of new documents, who do not get to copy those historical documents, while an AI competing with them gets to. If you want those historical documents to be freely available, make copyright stop applying to them. For everyone, not just massive AI companies.
I have a feeling that they are going to fare better odds, the world runs on money.
