Most of your post is very confusing, but I will mansplain a few things.
There's exactly two human factions that would. Eridani, and the Techno Conglomerate. Only the latter is said to have anything like this, and they are far away from Tau Ceti. However, this does not mean that eventually, humans can't have full body prosthesis.
Hated by who, exactly?
The Hegemony has no influence over NT.
Skrell have not seen this, they are probably just very wary about the 'Oss' part. Which, they'd be just as wary as the Aurora having an AI lmao.
Tajara have not seen this, we don't know how they'd feel. (They might like some cold-adapted prosthetics, maybe.)
Vaurca certainly do not care about the affairs of others in such a manner, have no influence with NT.
Dominia, we have no idea.
Elyra probably doesn't care.
Eridani probably likes it, even.
NT does not care much about what Sol thinks.
You will have to explain how it's being 'reached for', as this exists in lore already.
What do any of these things have to do with this?
What does this have to do with Aut'akh?
