Every time someone tells that something I use and enjoy is "the gen-z version" of something, I'm getting worried: is it me trying to keep-up with the cool kids?
Having a few "gen-z" in my team, I quickly came to the conclusion that trying to profile them in a single group was silly: they all behave differently, like every human ever did.
I think there may be two things at play here. One is that some people are just bad at adapting to social shifts and assume that everyone is the same way as them. The other is that people have gotten loose with usage of generation terms. So for some older people "gen z" = "person younger than me", while for some younger people "boomer" = "person older than me"
And both of those are problems with the speaker, so now I just ignore them and happily keep on doing the "gen z" things.
Anyway, the oldest gen-z is just about pushing 30 now, so they get to join us lame people with sore backs.
