why is the dominant aesthetic form of so much web-art brutalist?

its always plain text, default font, white background. its checkerboard transparent stand-ins, equal-width characters, source code visibility a must. i feel it pretends to a sort of transparent modernism, a text describing its own creation apparatus, but why then does it seem to me so nostalgic? these are all signifiers of old ways of using the computer, old by the time i got my first laptop (which was a very long time ago now). it feels like a stranger letting you know something awful dot com is the originator of online culture, not 4chan like you were taught. i guess it comes off like a pose, is what it feels like. i’m not coddled byt the convenience of modern computing, it tells you. i’m an operator, eyes inside

brought on by seeing this, though really this is a reaction to almost everything, a tantrum of things i dont understand
