Indeed, that is what I'm saying. Even though I'm a real person, when you read this comment, you do not gain any interiority into my real person.

You read my comment in your mind's voice, entirely with your own biases. And the fact that you choose to read & respond to my comment over any other means that the "conversation" we are having is with the disembodied voice (my voice) in your head with another disembodied voice (your voice) in your head.

I don't know you, and you don't know me; the exchange takes place on your side, within your ego, and only informed by your perspectives and biases. (Likewise, for me!)
