What is substitution for human organ?
-There are many substitution for human organ. For example, glasses substitute our eyes. and clothes substitute out skin, and cel-phone substitutes our memory, pinset substitutes our hands, and so on.
Are we free from them?
-I think we are not free from substitutions. because we are not naked in ordinary-because we wear clothes. and we use pinset, chopsticks by substitution of our hands. More deeply, weapons are substitution of our fist/kicks. In modern age, we are not free from them and we depend on them.
Ghost in the shell......
-The sub-title of animation movie 'Koukyakukidoudai'. In the movie, Kusanagi is cyborg police agent. Only her brain is nature human's, other organs are machines. So she is almost machine, but she isn't. But she is not human, either. In the story, she is in pain because she is also confused by the fact that she is neither human nor machine.
Machine artificial organs......
-Those are replacement of lost organs like a legs/arms. Many humans lose his/her own organs by accident/war like a Rugal Bernstein(in King of Fighters), Bando(in Elfen lied), Hyoma Aoi(in Combattler V)...and so on. They lost their own arm by suiciding/battle with other guy/in accident during rescuing other guys. So they gets new electronic arm.
Is human all same?
-The fact 'We are human!' is same, but others are not same-because each guys have many other thing. for instance, one guy can have dark skin, but other guy can have bright skin. and one can be male, but other can be female. and each guys have all different hobbies/feeling about an action/objects in life. So I think that all humans are not same.
Is cyborg is real human or machine?
-I can't divide human/cyborg/machine directly, and I'm confused that cyborg is human or machine. because cyborg is not human or machine. Cyborg has things of both side. Like a Kusanagi(in Koukyakukidoudai) or Maxima(in King of Fighters), They can have human brains, but they can also have machine organs/bones. So I'm confused by the question about cyborg.
