I think people are reading too much into the title—it's meant to be taken literally. It should also be obvious if you know anything about history; it's basically saying that we have always been a globalized civilization and our subjective definition of it is imaginary. And this is important because people really do believe in the idea that their culture is pure and free of outside influence. It's also more about globalization than immigration, which would be obvious if you actually read it. Once again I am disappointed by the quality of the top comments on Hacker News.
