I didn't add you, I just referenced you, but you're welcome anyway.
Aethermatons are distinct from Aethermatrons in that they have more simplistic programming. Mycroft and Sir Percy are programmed to be cats, little more. Your Aethermatron brain is so complex that I'm fairly certain it cannot be duplicated, not by human science anyway. In other words, Aethermatons are more like robots; Aethermatrons are more like people.
