Speaking for myself, everything I am that brought me to this group is probably based on years of overexposure to lot’s of mid seventies science fiction, mostly TV. So I grew up on shows like The Six Million Dollar Man and The Bionic Woman or films like Westworld. So in my own little feeble brain, those presentations represent the “correct” version of what a fembot should be. To that end, a removable faceplate is not just interesting, but required. It is, for me, what separates fembots from humans.
Furthermore, I think the idea of a mask implies a certain amount of deception, which was often key to the above-mentioned shows. I love the notion of something being other than what it seems and fooling everyone, but ultimately being revealed, or unmasked for what it really is. And for that, Robotman, gets my vote as the high priest of story writing around here.

However, as to engineering practicality of a facemask, I’m not sure it’s feasible or practical. Sure there are times when you want to “pop the hood” and see what’s going on inside, but how do you deal with the ever present “where’s the jaw, tongue, teeth?” question. I always felt the Bionic Woman fembots did the worst job of handling that. Don’t get me wrong, I loved the visual, but that flimsy rubber mask obviously didn’t contain anything substantial. I think for my money, I prefer the open face of the Westworld robots. It just looked more practical and, without creepy fembot eyes, even more machinelike.
So there you have it. Let the discussion begin.
