Such perspective isn't really so surrealistic, when we think about the lengths some governments and institutions go to stop people from talking to each other. Some countries censor the outside internet wholesale. Military conscripts are often chosen from more remote, poorer locations where people are less internationally-minded. Dividing people into ideological bubbles also seems to be a measure to stop people from talking to each other, in spite of sharing the same language and internet.
