I'm Gen-Z, my parents are older Millennials
Millennials use the Internet but they don't get it like Gen-Z does. Most of my peers seem to have a much better understanding of online culture than most millennials do. They use much more irony in both online and irl conversations.
One thing I noticed was that millennials have weebs, but Gen-Z doesn't. It's not something special for Zoomers to watch anime or be interested in Japanese media/culture. Almost all of my peers watch anime or consume some other Japanese media frequently. My parents didn't watch anime until my sister got them to.
Gen-Z is more individualist in less of a "the only person that matters is me" sort of way and more of a "you can't count on anyone, especially the government to help you" sort of way. You can see this through Gen-Zs political engagement. Most of my peers are differently engaged that millennials. Most people my age don't affiliate with a specific party, but rather by an ideology.
Also, Gen-Z is much more depressed
