I don't understand why you (and others) think this is an important point, though. Let's say, for the sake of argument, not just that you're correct, but that we're not even made of flesh. That we're actual robots called "humans".

I don't see how that changes anything. I'd still prefer "human" communication over communication from a different machine pretending to be "human".

Why? Because what others of my species/model feels and thinks has a unique importance and meaning to me, and having fake versions of that communication around reduces my connection to others of my species/model and devalues the society of them that I am a part of.
