It's a bit silly that the biggest thread in this topic is about sci-fi/realism, when this is not even remotely the concern of the movie. These really aren't the tools or context in which the movie is asking the viewer to explore and think about the nature of intimacy.

It would be akin to having a technical conversation about a framework, and someone derailing it to talk about the color of the computer case. You would be vexed to see someone miss the point so completely.
