This is a long, well thought out [theory] with graphs that ends concluding that the world is in chaos because there are more [is more communication than before, among more people, in more detail].
Note that changes in medium of communication have lead to political upheaval every time they’ve happened, whether we’re talking manuscripts to printed books (the Reformation), the rise of periodicals (nationalism), radio (fascism, socialism, the New Deal), cable tv (the first fracture in the post WWII US liberal consensus, as the ruling class had forgotten that amiable mostly non-partisan politics was an abnormal state of affairs that had been engineered) and now the internet (suddenly everyone realises there are large parts of “their” society that genuinely, non-ironically hates them and what they value).
If you go earlier every leap in communication technology makes more efficient bureaucracies possible, so you get larger states that are better at warfare.
Theory is too kind a word for this stuff. It's theory like critical theory is theory.
Sure, there have been massive changes in social organization that have accompanied changes in media. That doesn't say much though. Those changes compound and interact in unpredictable, chaotic ways. We like seeing patterns so we come up with stories about how we're either reverting to some imagined mean or how we're converging on another.
