I mean, are they materially worse than Paris Hilton and Kimberly Kardashian? Or the Jersey Shore crowd? I'm not here to judge.
But I didn't really follow them when I was age-appropriate to care about that shit, anyway. Was too busy reading blogs about the newest feature list of an up-and-coming MMORPG or tearing through the latest edition of my favorite TTRPG, because I was focused on what truly mattered.
At some point, its not an age thing, its just a taste thing. I could probably name more web comix artists and indie board games than C-list celebrities and Reality TV shows, and that's fine.
Listening to what their interests are is a good way to connect with much younger (or much older!) people. I'll happily listen to a kid explain Fortnite to me, or my to grandpa talk about his favourite TV show. I'll ask them some questions about it and get a conversation going.
