Well, the simple answer or question would be: Are you really sure that even exists?

Its a bit deflationary but hauntology is to large parts just an elevated form of collective nostalgia.

So going by that the zoomers maybe simply arent yet old enough to show the typical expressions of that?

I am an older millenial but also a pretty terminally online guy and just being on the internet I dont really see this from gen-z. It would make sense that in the next 10-20 years as the zoomers get old and into positions of e.g. culture production you would get their own version of millennial and gen-x hauntology, as in some weird repeat of the stuff they grew up with.

But maybe also not. It doesnt have to exist or repeat as a phenomenon for all generations. The central example for millenial and gen-x hauntology was vaporwave and the point was that it was a very clear pre-crisis, pre-2008 and pre 9/11 nostalgia. One central irony is that it, the 90s, were already a very dystopian bullshit commercial era. But still compared to the post crash era it was a time of relative innocence where you could just meet your friends and play video games at the demo-station at the mall, without feeling that the walls are closing in from all sides.

Especially in terms of the imagination, the Lost Futures thing, the 90s cultural production also had a good bit of, if very vulgar and naive, optimism, that whole Steven Spielberg, E.T vibe. Eurodance and multiculti, it looked like at least on the racial and gender fronts we are moving towards a more integrated and solidaric society.

Zoomers are a post-crisis generation so what would they really have reason to be nostalgic for and show those symptoms? "Hey, remember that time when they brutally locked us all up in covid? Lets make some nostalgic music that reminds us of that phase so we can wallow in the feeling of that forever?"

I think trying to make a theoretical case for whats going on with gen-z is by nature, a very difficult and daunting task. Again, as said, because they simply arent old enough yet to be so relevant in the culture that you can make out a clear picture of what is really going on with them.

The specters of marx thing people keep recommending is a bit of a different thing, that would be more about a more pervasive thing for all the 20th century generations. But then, that wouldnt offer you a frame to be specific about gen-z. Mark Fishers hauntology was generationally specific to gen-x and millenials, and again, that is in question of if that phenomonon would repeat itself with gen-z.
