This "Generation" thing is only a tool for market-targeting, anyway. So people can sell you shit.
I do see differences - good ones, I think - in younger generations bringing about a lot more change, e.g. refusing to accept status quo. BLM, LGBTQ, ERA, civil rights, justice reform, addressing climate change, fair pay, balanced life and work, refusal to accept rape culture, etc., it's all great stuff. I have great faith in our younger generations. They can't do it alone, though; we need to help them.
P.S. - I threw my old copy of Manson's book into the recycling bin today. It was the only Manson thing I owned. (Edit: I had to find it, first.)
