Actually there is, in the (stated in the movie) supposition that what you can think about is bounded by the language you think with. Corr.: learn a different langauge, change how your brain processes your experience. So learning Heptapod changes your sensation of time, because time is a fundamental component of the language. Note how her future experiences become more detailed, less fragmented, and more focussed on "current" context, as she learns more about thinking in Heptapod. Not just revealing it to us, the audience: showing its progressive revelations to her. And then she writes the book on it, for the rest of us. And thus closes the loop.
