I agree, and as the article makes clear, this current liminalism really does not come from the world of "High Art":

>As an internet phenomenon, the most recent iteration of liminal aesthetics can be primarily traced to a 2019 Creepypasta collaborative short story entitled "The Backrooms"

This is ground-up, the opposite of high art. It's even kind of "outsider art".
