You could make that case for the boomers, but with the advent of the Internet it’s not really limited to specific countries anymore. Gen z just describes people who grew up with some access to the internet, but not to the extent of alpha. A large part of these recent revolts were caused or accelerated by social media. Gen Z is more specific than young people, and in this case also more culturally relevant.

Doesn’t matter anyway, even if you think Gen Z isn’t real you know what age range the article is talking about.
