Not a vtuber but there is a streamer called hafu who by her own quote "doesn't know how to boil water", she scored a boyfriend whom she married in 2021, her husband, a hearthstone streamer called Dog, doesn't know how to cook either. They survive off UberEats.
Riddle me this "
how many male vtuber does it take to replace a light bulb"
The degeneration of skills goes both ways for the male populace too, basic plumbing, car fixing, woodworking, eletrical wiring, roof fixing, etc. things that husbands from the previous generation are expected to do, not many male from the fortnite/league of legends generation can. How many streamers do you think have ever held a screwdriver?
They are as much of a failure as the "girl failures" you guys are looking at, and thus standard for dating/marriage also degenerated.
If anything, age of bearing children goes up because more "failures" paired together and physically can't raise a child.
Sure male vtuber are an endangered species, but streaming and gaming as a whole is dominated by male, it aint hard to meet one if you e.g play the same game. With Valorant/Final Fantasy e-dating becoming the most popular platforms.
