McLuhan got a whole lot of stuff right, but I feel like the “global village” turned out to be a Potemkin village. We don’t concern ourselves with “everybody else’s” business. We closely watch only the tiny fraction of the world that’s magnified by its popularity until it seems like everything. The selection is wider and more diverse than it used to be in the days of television and we have more channels to choose from now, but even the most carefully curated fediverse feed is still a long way from seeing the whole world or the whole picture of any big part of it.
