"How do informational norms change when we’re all living in the same universal room?"
I different interesting question: why would we want to inhabit this universal room in the first place? The post mentions the idea of being "bigger than yourself" but to me the context collapse achieves the opposite - a sort of carboard caricature of oneself.
From what I’ve observed, people are increasingly checking out of social media (or turning their profiles private), because it’s just unappealing unless you’re actively promoting something.
