But my question is about your point of scale.
I don't understand why it should be allowed for one savant to study and answer questions about one book, but wrong for a company to hire one million savants to answer questions about one million books.
And I'm asking where in the law or case law this is supported.
That's not what I said. The concern is not about "answering questions" about original works. That would probably be acceptable at any scale. It is whether the approach foreseeably results in the creation of market substitutes that compete with original works.
