Maybe I'm old too, but I don't have a problem with avatars and virtual ones, it's the extremely high pitch and cartoony voices VTubere tend to have. And why does it have to be anime or furry aesthetic every time?

Give me Optimus Prime doing kernel Rust coding. Even better, gimme the sarcastic high pitch of Skeletor. I'd also be fine with, I dunno, Lara Croft or other virtual female character.

Everybody has their own preferences, fine, but outside of that overrepresented niche of sexually ambiguous anime and furry there's just... nothing.
