"they're not doing the traditional things anymore now that they see there's a whole world of people with different traditions and situations" I get theres people who want to keep traditions alive because they're traditions but also... What is really the point?
After skimming the beginning, it seems the argument is that there are probably lots of latent survival tools built into their (any) culture. If they take up the internet as a past time, they will stop doing this other past time that has benefits for the survival of the community in their particular location. For example, if they stop playing some game about colored rocks, the ability to differentiate colors will diminish, eventually causing them to be unable to properly distinguish berries in gathering activities, leading to the end of their society.
Well, sort of. It’s much deeper than colored rock games. It gives a good explanation of why people idolize sports stars, why it was beneficial to a culture to “read tea leaves” for some things. It basically explores all kinds of traditions/culture that seems dumb to modern people but argues that each one is specific to its area and is humanity’s super power as opposed to just our big brains.
