Human beings have always been mythological beings. It's just that the myths that they now believe are amplifications of their own beliefs, or what they want to believe, rather than the collective beliefs of their societies, elites, thought leaders, and media masters. So yeah that's doomsday for society, in that there are no longer any shared myths holding everyone together. Those myths were never really true... they were just a tool of control, maybe even self-control of society. Without them the chaos amplifies.

Heck even without social media it seems like there was a progression in politics where things were becoming unhinged. Things were becoming more and more polarized and what is/was considered progress was more further and further from many people's ideas of progress. So there is a series of issues that are coalescing together in our time with a background in the century of self, identity politics, etc.
