One place where we might agree: a singular service or collection of similar services being able to replicate the entire population of humanity reading, digesting, and redistributing these concepts and ideas is a bit different than it has been throughout the pre-ML part of human history. You would need some sort of singular individual with an impressive photographic memory, and the ability to answer questions from millions of people simultaneously - which clearly is not going to happen. So we just haven't had to deal with it yet. I would agree that is an important distinction.
But the original premise: some agent is able to take my words, distill them into something else, and utilize that distillation to form a model of the world to be re transmitted is identical to humans communicating and thinking. I'm a big proponent of sharing information, so to me this is a net positive - in fact, it turbocharges my hopes for an "information wants to be free" society.
But if you want to keep your knowledge, wisdom, and communications behind lock and key and charge for entry, this would absolutely be the opposite of what you want. You're absolutely allowed to want what you want! But I'm also allowed to want what I want too, which is why I won't be joining team ban-computational-modeling
