>for the people who get it
Yea I love fiction. I certainly get it.
You should think this way about a particular thing because this one movie portrayed it that way, and if you don't it's because you forgot that this movie portrayed it that way according to its creators will, thoughts, ideas, motivated reasoning, worldview, whatever...is not compelling.
It's pretty obvious to me that the creative choices and ideas of certain people do not imply any demonstrative truth about reality just because they exist because there is not a direct connection between the two; someone can write or film or render whatever they want, even completely contradictory versions of the same topic. What if for example someone did watch that or any other thing and simply disagreed? Think the creators got it wrong?
> public discourse about possibilities. to me seeing it as arbitrary
It's not arbitrary. It can certainly be self-serving, it can be propaganda, it can be a good guess or a well-meaning statement about reality, or speculative fiction but also wrong. It's just the emphatic certainty in how you presented this media creation as proof of something inherently connected to truth about a complex future debatable quality of reality, as even a fictional account about history or the present day or politics suffers from obvious fundamental disconnects from being regarded as "truth", proof or evidence of anything. Again, different people can make multiple contradictory or competing portrayals of a certain concept or topic. This is no different than someone telling you what they believe about a thing; it's not "therefore true" as such, especially in the form of a prediction about the future.
