I think there is a sort of micro view where that is true, but also that culture can change very rapidly in many ways. It might not be entirely pleasant, but I think society could handle a permanent 1960s level of change. What worries me is e.g. the much more recent phenomenon that siblings a couple of years apart are active on totally different social media sites, and have different social norms and practically different language dialects as a result.

Yeah, makes sense to think of this level of fragmentation as a qualitative difference.
