I just watched Arrival. A great Movie and quite deep on many levels too. Requires watching a few times. Anyway, we see that as Louise learns the alien language, she starts seeing the future, or rather sees time as non-linear. My question is, that it seems that she is not the only one who learns their language, the Chinese and Russians seem to have communicated with them too and thats besides Ian, who learns the language together with Louise.
So why is she the only one who now has a new perception of time? We know the others don't because she was the only one who spoke to the Chinese general, Im pretty sure the Chinese scientists were a lot closer. Also, Ian didn't see their daughter dying, only Louise did.
