K Pop groups (from South Korea) are manufactured by promoters and agents, and standardized in the extreme to please international audiences. So, this is the next step: make them virtual with the help of avatars and A.I. The stage after that is to have virtual audiences listening to virtual performers. Let's do away with human beings completely: they are too imperfect, messy and fractious. The Metaverse will be a happier place for all of us.
Reminds me of the clearly prophetic movie Simone (2002 film) - Wikipedia, a case of Life imitating Art!
