This is great science fiction. All good science fiction asks a question, which is essentially, "What would it be like for people if the world were like this?" It can be a small thing, like a decision to have everyone die at a certain age, or in this case, what if everyone else was part of a group/hive mind. This gives you a space to explore the human condition, sometimes to the point of what even is a person. One of the knock-on effects is, this strongly independent person gets to realize she is and has always been dependent on multitudes of people she never even sees, just like us. That's what civilization is, and they spend just a few minutes on that particular part in the second episode, perhaps elsewhere (I'm on episode 3). It's an uncomfortable thought for some people, particularly Americans and their fierce individuality. And it's very clear from the name on out that individuality is going to be the subject of the entire show. It's a pretty relevant topic in our increasingly connected and interdependent world.
