Gen Z is what you get when people grow up with the ubiquity of the internet and a bleak outlook.

Only Gen Z that's hyper involved in certain forms of politics(and you'd find people of any generation are pessimistic when they're involved in those same forms) like most Gen Z on here. I'm Gen Z, and of course so are most of my friends- we're pretty optimistic. But, I guess, generalizations based on generation have always been pretty meaningless.
