Jesus, that's so silly.
Isn't that just what 2020 needs however?
EDIT: I think this thing is basically going to explode much more next year. It's popular enough that related industries are going to want a piece of the pie. Hololive actual anime, when? But the question is whether this would even work as an anime adaptation. As Gigguk mentions in the overview video, he barely has time for anime this year as all his attention was taken by this Hololive stuff. So the whole general thing of "this thing is popular let's make an anime out of it" might not even work, if this stuff is more of a direct competitor for people's attention with anime than say mobile games.
I'm not sure it will explode in the fashion of anime, but if Hololive's mapping software is somehow leaked, or if someone releases a similar program without being proprietary, the standard facecam will mostly disappear (or become niche, as streamers that don't facecam at all are at the moment) and things will level out to a new normal with everyone just being virtual-tubers. There's got to be a lot of suits in the entertainment industry salivating over a slice of this pie.
The next big leap is going to be replicating voices, and god, will I ever hate that. I already detest the standard immature cutesey voices on female characters in anime, a trend which carries over even into dubs, but imagine if vtubers now just license and replicate all the popular anime characters instead of just using their own human voices. (The trash taste podcast covered this a little in their newest episode where they had Mori Calliope - one of the HololiveEN characters - as a guest.)
Well, I guess it won't make much of a difference to me since I don't actually watch streams all that much. The occasional clips are fine, but I don't know how people watch the same streamer 2 hours a day, 10 hours a week.
I guess there will also always be a demand for "natural" streamers, as I think the desire to avoid a manufactured personality that most entertainers have is part of the drive toward streaming. To be sure, major top-earning streamers have benefited from playing a character, or at least tweaking their on-air personality, but the bulk of streamers - the ones that only make a few thousand a year doing it - are more sincere.
