Half duplex is a monologue
full duplex is a conversation
But still and all, voice alone is only a fraction of how and what we
communicate, or better put it is just one tool we use to express
ourselves, most times with out knowing we are using those tools at all.
Facial ticks, breathing, eye motion, finger twitches.
There is still a very long way to go until full-humanplex communications
are realized over the lines, data or voice.
