Gen X here. What made us uniquely who we were is that we were the first generation to know that the boomers were full of shit. It was a loss of innocence.
And MTV. It's interesting to observe how little is relevant anymore what we grew up with. And it's getting faster and faster. Social media in it's current form will die too in the next 10 years or so. Memes will prevail, though. They have to.
