Could it be you've been interacting with the "parents" generation which supplies the internet for the kids but does not get WEIRDed. Kids soaking in YouTube, gaming - it's creating a geek monoculture. There are backlashes, sure, but I don't know how well they can keep the tide at bay.

Anyway as a parent of 11 and 13 year olds this is the vibe I get. They are much more familiar with memes and internet "things" than anything I would call 'traditional' culture in my country (Finland). Of course we are in the west, so not sure what the situation is elsewhere. But it sure looks like getting more WEIRD (I mean rural folk not speaking english creating youtube channels to present their traditions to a global audience - how can you hold it back (unless you are a large authoritarian nation state).
