Honestly as an older git.
The whole idea that the younger generation is not interested. Is hardly a new one unique to gen Z.
Pretty much every generation since the 1900 has been accused of this.
The only difference is how much change in culture each generation has had to face.
Honeatly pre 1900s. One generation did not face much change from that of their grandparents world. Since then each generation has seen more change then the last. As technical groth has sped up notable even in my 50 plus yeae lifetime. The changes have been notable.
But each generation. As they age a % develop interest in things to a higher level. Little indicates gen z are any different in this.
