This wretched world will find a way to commoditize everything.
VTubers on a technical level are nothing new. Software such as FaceRig has been around for years. It's funny to whip out a cam feed and surprise the audience - the guy behind the mic is actually a talking paperclip. It was generally obscure enough that poor usage was looked over.
What's not funny is some dumb bitch (or guy) using these 3D avatars and plastering them onto the screen 24/7. These niggers could have followed the trend of putting their ugly mug into the corner of the screen while they stream. But that's not good enough. They only think in terms of business. It's all market share, "making markets", revenue and viewership. There are plenty of people who think they're hot shit for tapping into this type of thought.
There's some images or articles out there that describes the process of how niches and hobbies with honest practitioners (read:nerds) get exploited for profit. VTubers are for people who like "the anime" and also "the videogames" but are complete secondaries. If VTubers die down so will their desire to watch them. They will simply latch onto another thing. They are consumers in the most degenerate sense.
Imagine being on an anime board and all of a sudden these stupid 3d avatars that have no merit start flooding in. The discussions are noise. Countless threads fill your catalog but nothing can be gleamed from the words within. It is so bad that you could replace the VTuber names with actors from Bollywood and not think twice about it. That's how shit they are.
