collapse of the old society

Defining an age while it's happening is the same mistake as trying to define a generation outside of an historic context. You either use arbitrary boundaries to define the category, or you wait for a historical context to define boundaries and categories under. We're in the ages of glass, plastic, misinformation, cowardice, social networks, corporations, etc. You have no idea what the defining characteristics will be to history until you are looking back from the next category or epoch.
