I would just add that that is very consistent with what I was saying about future-proofing the Copyright Act in a sense, by not needing to come back to constantly revisit on questions like “What about text and data mining now?” or “What about fan fiction now?”
New kinds of uses will emerge as technologies evolve, and the question should be whether those uses are fair and should be permitted and are consistent with the objectives of the Copyright Act or not, rather than giving as another thing to argue about whether they can fit within this narrow purpose as defined in the act. Then we begin parsing things like private study and study in classrooms, or we start parsing things like news reporting and reporting current events and what are facts and what counts.
Whenever we have these specific enumerated purposes, we actually create more uncertainty, I think, because we are more concerned with what those mean and how they apply in new contexts than with the bigger picture.
