idol system as we know if today and what’s being ported over to other Asian countries is very much kpop-ified.
I agree on this point. But where our opinions may differ is that I think that the countries that copy this system do so by copying a marketing style above all else to be able to export as well.
The west is not jumping back on the GG/BG trend
This model is indeed not taking off in the West. But it is reductive to forget that idol groups once existed in the West (Backstreet Boys, Spice Girls, One Direction, etc.). And this model of boy bands/girl bands from the 90s in particular was a source of inspiration with the Japanese idol model for the creation of kpop.
