>>42859No, I wouldn't say so necessarily.
Since early-imageboard culture was literally just offshoots of SA (or in 2ch's case, BBS) culture, it was basically the same. With modern imageboard culture, it's a far cry from its original days, but most of the reasons for that have nothing to do with 4chan.
For example, the death of traditional forums was because of social media, and social media culture has grown to dominate the west.
Social media culture and memes are usually just chewed up seconds from 4chan, but if there was no 4chan, there'd be some other site to take its place. It isn't as down to earth, but I would hardly say 4chan ruined the internet, it was doomed to be shit via corporate meddling, it was imageboarder memes that helped us through the shit.
Tiktok retards, facebook boomers, all of these types of people would have existed with or without 4chan. Imageboard culture hasn't significantly effected the west.
