I'd like to know what world you live in that Gura earning 40-50k subs per week is plateauing.
you see, people have been predicting Vtubing "plateauing" for almost a year now, so now any slowdown whatsoever will be claimed as "see look the plateau is happening"
Are we in schizo meteoric rise mode like we were this time last year? no of course we aren't
But Vtubing overall is still growing quickly and healthily, Hololive EN2 isn't skyrocketing as fast as EN1, but they are still outpacing anyone else in their market by a long shot overall.
Even Nijisanji where everyone so commonly gripes about their debut speed is still doing great, Niji I would say is doing even better than they were this time last year. Their latest JP wave was a hit, and EN is paying dividends for them.
I think folks just have their perceptions skewed by being holocentric at the time of Hololives greatest growth period and now anything less than that and suddenly it's "the golden days are over, the plateau is here"
Just because it's not growing at turbo speed doesn't mean it's not growing quickly, Just because you can't personally follow every single chuuba you want doesn't mean it's saturated If the market were really dying down and oversaturated Nijisanji just wouldn't be dropping waves like they are, they aren't retarded, they're doing it because it keeps working out for them, if it weren't they'd shut it down (NijiIN anyone?)
A good first step for most people would just be to stop using hololive as your baseline because it's far far far far from the norm and has been for quite some time now.
