Fast moving field does make sense in terms of copyright because the knowledge is recorded in documents which are then copyrighted. E.g. research papers.
> If I write a really popular book, I don't want Hollywood to make it into a movie without compensating me just because they waited a few years
I genuinely don't understand this. Even at a decade copyright, pretty much anybody who was going to buy the book and read it has already done so. It costs you virtually nothing in sales, and society benefits from the resulting movie.
Your goal is to deprive everyone of having a movie, because someone who isn't you is going to make some money that was never going to you anyways? Your goals for copyright appear to be a net negative to the system that enforces copyright, which begs the question why should the system offer protection at all?
