John Carmack always has an interesting point to make about latency: https://twitter.com/ID_AA_Carmack/status/193480622533120001

and to relate to the other post about landlines: https://twitter.com/ID_AA_Carmack/status/992778768417722368

Is there somewhere to read about the changes in question?

I'm old enough to remember extensive use of analog landlines, and can't really think of any difference to a cellphone other than audio quality.

In my world, using regular cell service (not VoLTE), seems nearly as instantaneous as I remember analog lines. I remember how hard a satellite phone call was and I never have that much latency in a call.
Isn't this mostly because actually showing a pixel requires a macroscopic change?
