What I think is interesting is how much worse the conversation experience is today vs. during the days of circuit-switched landline phones. There was no perceptible difference between a live conversation and one by phone between New York and Washington DC. Today the conversations seem so stilted because there's 50+ milliseconds of latency at a MINIMUM that makes interrupting and a back-and-forth conversational flow absolutely impossible. Also lost completely are the little "ahs" and "ums" that add color to a conversation.
