No, I don't think its too pessimistic. In fact the illusion of a global digital village lasts longer than what one might expect, probably because of tech illiteracy and the capture of various local elites. But I also dont think that the hippy technofiles were all wrong. Ironically, when you combine the finite Earth with extreme levels of digital information gathering and the zero cost of replication and transmission it is very hard to keep silos. E.g., pretty soon automated translation is a thing (and I am not an AI bro :-). Also you cant do much about joint dependencies on environmental deterioration without global coordination. How its going to play out is unclear but the scenario of the same old clans fighting it out in the same old ways is not a given in the longer term. There are centripetal and centrifugal forces. For now the pattern seems to be tearing apart.
