You give too much credit to Holo. I foresee Hololive turning out like the vtuber version of Valve in the long run (overseas), not the most popular, since I think the westYamanbas and normies will end up preferring indies like Filian and Shylily in the long run, while the weebs will be divided between Holo and other agencies (whichever survives). If Holo doesn't implode then they'll settle into this "Pretty consistently good, with few controversies, but not as great as they once were" role, I don't think they will ever recapture their 2020-2021 popularity in the west. If their games and VR shit works out then they will likely shift focus onto that and have the vtubers as advertisers for their multimedia projects (what they were always meant to be).
