criteria of social development of civilization.  if our planet is ever visited by guests from other worlds, the criterion for the development of their society will be the presence of a non-hierarchical social model. since our society has a "hierarchical" model - we are socially underdeveloped. the human species has a limitation of natural hierarchy, which is a dead end in social development. such development leads only to the creation of the hive, regardless of the achievements of technological progress. if an alien species arriving on earth has the same type of social development - that is, "hierarchical", then earthlings will be forced to obey it. such species (as well as the human species as a whole) should be feared. if the arriving species is non-hierarchical, this will mean that it has repeatedly socially surpassed itself, most likely for such a species people will look like a bunch of insects-npc.
