Thus, I stand to receive about $9,000 as a result of this settlement.
I think that's fair, considering that two of those books received advances under $20K and never earned out. Also, while I'm sure that Anthropic has benefited from training its models on this dataset, that doesn't necessarily mean that those models are a lasting asset.
Infringement was supposed to imply substantial similarity. Now it is supposed to mean statistical similarity?
Given that books can be imitated by humans with no compensation, this isn't as strong as an argument as you think. Moreover AFAIK the training itself has been ruled legal, so Anthropic could have theoretically bought the book for $20 (or whatever) and be in the clear, which would obviously bring less revenue than the $9k settlement.
So you're agreeing with me? The courts have been pretty clear on what's copyrightable. Copyrights only protect specific expressions of an idea. You can copyright your specific writing of a recipe, but not the concept of the dish or the abstract instructions itself.
