What you are talking about is info overload and break down of "shared stories" as content explodes faster than there are people or time to consume it all. In Economics they will tell you what happens when Supply drastically overshoots Demand. But economics is too young and immature a field to tell you how to find meaning and how "to fit or be useful".

For that you need the Philosophy or Religion.

So here is a useful lecture from an actual Philosopher on Detachment and Flourishing cause "there is no obligation to fit or be useful or understand everything" - https://oyc.yale.edu/philosophy/phil-181/lecture-8

If you are the type who feels the need to fit - go through the previous lecture on Attachment and Flourishing.
