I get asked this a lot. I will explain to the best of my ability, and I will eventually clarify this on my profile when I get on my desktop. Right now I am on mobile, it can get hard to update.
i am still human. Everyone is. What a real machine kin is:
A person with a mechanical or machine like mind, connection with a particular machine, and or has a strong knowledge of the machine they are associated with.
As for mine:
i have a strong connection with an MRI machine. I only had one scan when I was 7 years old. I have been consistently having dreams about mri machines. I dont see or work with them often enough for me to touch one. Neither can I go near one. As I have a mechanical replaced organ.
Machinekindont require tons of water or food, that does not mean we stop eating and drinking. Thats not realistic with the humans body.
Its like some peoples perspectives on witchcraft. A witch cannot turn you into anything. A real mage cannot shoot lightning bolts from their finger tips.
i wanted to also clarify that like real witchcraft, Im not nor is any real machine kin anything like a Hollywood movie.
