> Circuit switched analog POTS has been dead for a long time, but delays were limited to amplifier delays (almost nothing) and speed of light in wires or radio.
Two questions about this: it sounds like there are still a fair amount of landlines around if this article is accurate: https://www.cnn.com/2024/02/05/tech/landline-phone-service-p... Do you mean that people still have landlines, but they're no longer circuit switched analog? And would that only be for long distance, with local landline calls still using circuit switched analog, or would it be for both?
Also, as to your latter point about old school POTS having almost no delays other than speed of light: does that hold for long distance calls as well? I get the impression that there could be added latency for long distance POTS calls (but have had trouble finding sourced numbers on anything yet).
