I sort of agree with you, but the term has gotten fuzzy. It has become a
synonym for "delay". Real-time systems always accept input and usually
provide output at the input rate. Since zero delay is rarely achieved in
systems that actually accomplish something, it follows that the delay
between input and output must be fixed in one-in-one-out out systems. I
don't choose to argue with those who call that delay "latency" as long
as the meaning is clear.
