Put me in a vat, I'm not going to make moaning or breathing sounds in my mind. And it seems like a pretty silly engineer who'd simulate such a thing. That's really my point. If it was a cartoon I couldn't care less, but I like my sci-fi to approach some level of realism. (and I'm really not the type of guy who complaints about sound in space, it's about immersion for me and a breathing and moaning robot kills it for me.)
Amputees still 'feel' the missing limb months and years later, so I find it plausible you would still 'feel' reactions in your body even if you no longer had one. I didn't take the sounds to be literal, just an artistic technique.
To be clear though, I think your opinion on this is every bit as valid as mine, I just really enjoy discussing film.
