Okay serious talk
I get it, zun added an ai background to prove a point, because the game's plot involves ai, he's not pro ai.
HOWEVER, I have one big problem with that statement
Why did he use ai in the first place, why couldn't he just NOT use ai and have one of the characters say "reimu this stage is ai generated lol" ?

AND if he did use one singular ai background why didn't he go all in and ai generate an entire 2hu character with her stage ai generated as well? WHY JUST ONE FUCKING BACKGROUND
This doesn't look like a "stroke of genius" as some people say, it just seems lazy and half-assed to me.
