#good to bear in mind
I think an important instinct you have to build up when you read/watch sci-fi is discerning which things are givens. If Arrival tells you that the alien language is atemporal, it is, that’s not a puzzle for you to pick apart, it’s a prerequisite to getting the rest of the story. When I talk sci-fi with people who don’t consume a lot of it this seems to be a thing they get hung up on.
“But why—“ because it make story go. “But I don’t understand what—“ because that’s how the society works. I told you the important parts, the parts that are relevant to the story. I’m not interested in writing a 200-page speculative history Re the entire course of galactic civilization to explain why it’s rude at dinner time to eat before the ambassador eats. “But I don’t understand how (whatever) works—“ it works because it’s science fiction and that’s how it works. The propulsion systems work because the story requires interstellar travel.
I am more interested in the people and the events and the weird ideas. The weird ideas are just weird ideas, this made up fiction story isn’t a thesis statement predicting why cockroaches will be skilled surgeons 10,000 years in the future.
I think this is really important for writers, too. I know I get hung up on worldbuilding details and it’s good to have a reminder that I don’t need to reinvent DNA just for an alien to have green skin.
In my old critique group there was a dude who DID explain every. little. thing. in his huge, sprawling sci-fi world. And trust me, it was horrid.
