> they want to talk to those business-y people in their own vernacular. I don't think it's about using their language for understanding. I think it's because they want to send a signal "Look, I'm like you. Let me be in your in-group." It's a tribal signal. > but they do't realize we could all just agree to stop doing it and we'd all be happier. The problem is that everyone wants to be in the high status in-groups, but the high status in-groups don't want to let all the rabble in. This is a perpetually unstable equilibrium. Once any given high status in-group signal becomes widely known by lower-status people, it ceases to be a useful signal for actual high status people (and, worse, eventually becomes a signal for "low status person trying to look high status") so must be discarded and replaced with a new one. Once you realize it, this phenomenon is everywhere. It's the engine that drives almost all of fashion. It's why buzzwords and jargon come and go. It's where home furnishing and interior design fads stem from. It's why so very few things in our highly social human lives are ever really timeless.
