Overall, I think a dimension perhaps lacking in PG's otherwise fantastic writeup is that this 'fragmentation' opens up a space of freedom. I mean, our society basically interpolates individuals (younger generations at least) as existential subjects - no set path on what we should do with our lives, no God, no religion, we have to make our own meaning. Painful and difficult, but a source of freedom either way. Today I can travel as a digital nomad, found a startup, work for a rocketship, work for a stable, high paying company, freelance, or switch careers altogether. I get to choose who I associate with and date and marry (and it's even acceptable to not marry), while choosing from a much larger, more open pool, and for the most part, I get to choose who I am. Not everyone has access to this freedom, but it's still the point in human history when the largest number of people have ever had access to this freedom.
