I suspect the mind is like the immune system, it needs hardship to develop into the best version of itself. Without external assaults that induce the formation of strengthening mitigations, you're left with a system that is dysfunctional, even self-destructive. In the case of minds, we discover meaning through battling and overcoming hardship. A life devoid of hardship is devoid of the impetus to discover personal meaning, which leads to these kinds of empty existences we're seeing much more of. The last 20 years has seen an intense effort to rid childhood of any hardship whatsoever, while providing a controlled environment where one's formative experiences are managed to a degree as to remove the possibility of any negative circumstances or emotions. But this just optimizes for the wrong thing. A development without challenges, conflicts, hardship, is a stunted development. This society-wide crisis of meaning is only going to grow as we continue down this path towards a hyper-connected world.
