I've noticed that millennial's (my age) Went for the 60's and 70's hipster thing, Record players, analog watches, you know the drill. I know quite a few of the generation Z kids and they seem really into the 80's and 90's stuff, Many of them are wearing reproduction Casio Digital watches circa 1985, those big round 1994 glasses, the clothing ect, When I talk about my boomboxes and cassette tape collection, they seem to really enjoy it, It's entirely possible that cassettes will make a comeback! If anything for the low tech hell of it, I actually have friends in this age bracket that have made each other mix tapes..... On tape! lol!
