The only reason we think of causality as moving forward in time is that we subjectively experience time as flowing in that particular direction.
There's no a prori reason to say that event A causes later event B. It's equally logically possible that B is causing A.
Really though I find it more meaningful to say that directional causality is a hoax and time is a static series of connected relationships.
@starkatt omgomgomgomg have you read "Story Of Your Life" by Ted Chiang? if you haven't I have it and I can give it to you! it is relevant to this discussion. XD
@green yesss, and seen Arrival :D
@starkatt I will definitely have to check that out at some point then. :D I'm wildly curious to see the visualization of what the aliens and their writing look like...
@green Oh it's so good.
Me, going in: "okay so how are they gonna make a language seem genuinely alien?"
Me, midway through: "ohh, that's how."
@green So it's actually an incredibly well-done adaptation imo. Emphasizes a totally different set of points to make it work better as a film, without losing the same core. Also it is absolutely beautifully shot and edited.
