Most of this stems from a misunderstand of how LLM work.
The original work is not stored anywhere. No copy of it has been made. Just tons and tons of statistics used to inform models.
Since there is no copy there is no violation of copyright. Again, no copy of the book is getting made. The content of the books is not stored "verbatim". The book is not copied. I don't know how many other ways to put this.
Summarizing a book also does not require one to have "read" it, contrary to the complaint. I never read "The DaVinci Code", but I can give a summary of it.
With assertions in the complaint being clearly false it's hard to take it seriously and it'll get chucked the first time a judge has to deal with it.
Maybe Silverman would have a point if it were standard practice to pay royalties to people you get inspiration from. But she doesn't pay everyone who wrote anything she read, said anything she heard, or other comedians who influenced her. So why should someone influenced by her pay?
If I read 100,000 books how do you determine "which one" I got inspiration from? Same situation here.
