>>11453157I doubt there will be any giant crash and burn doomsday phenomenon that kills all of vtubing from one day or the other. in fact, I don't think vtubing will even die. Hololive, Nijisanji and the like will all eventually fall apart and disband, overshadowed by other things, but just like pirate radio stations, videogame streamers, public television and podcasts, now that the technology is here, people will continue to do it until the end of time.
This chapter of our lives will close in time, in particular I predict Hololive will fold once their talents graduate en masse (which may not even be caused by drama but just by them naturally outgrowing the career, at worst it may be precipitated by a holo dying of an illness or something) and they decide to simply say goodbye rather than run a replacement scheme.
The industry is likely to be absorbed by corporate propaganda, but despite what you doomposters may think, this will ultimately change very, very little. Corporate mascots are a thing. Corporate spokesmen are a thing. Combining the two into one will not cause the end of the world.
