i've been thinking for a while that being really intensely into music (as in, prioritizing it over all other media) seems kind of outmoded. the Kids' energy and excitement feels like it's a lot more centered around video games and the surrounding culture. (or, yeah, even around theory in some cases.) that's my intuitive reading of the pulse. obviously on some level it's ridiculous to say, since they're both an ingrained part of people's lives, like saying food is more popular than shelter. but i honestly think it's true.
when i really became convinced was with the travis scott fortnite concert. how people were losing their shit, utterly amazed, but it had everything to do with the visuals and nothing at all to do with the songs. i don't think they even modified the original audio in any way? so the music was very perfunctory. if i were a creative, adventurous little kid experiencing that, i'd start wanting to be a video game animator and wouldn't give a thought to music.
kind of like how teens used to be really into modifying the cars. (or so i hear from my dad lol.) it's still obviously a subculture that exists, around a topic that everyone engages with in some way or another. but obsessive interest in that is no longer a cultural force. you have to assume that there are forums around that hobby, full of boomers speculating as to why they're not getting many new recruits.
