4chan is almost 20 years old, it may have been a countercultural element but I assure you kids these days are not on the chans like they once were. If it is still a cultural touchpoint for males 18-24 it is unlikely to remain so for much longer. Your yardstick for cultural relevance centered around creative AI usage is myopic when compared to the interests of actual younger humans who presumably would make up the counterculture.

What is hilarious is that by your definition it is concevable that the increasingly old men who continue to use 4chan could infact be the counterculture you seek... so in 60 years they will all be dead anyway (vax or no vax)
