NieR:Automata asks the question multiple times of whether androids or machine lifeforms are more human or imitating humanity better than the other and this is portrayed with... so much delicate complexity I keep thinking about it.
On one side you have androids who are human in appearance, human in intelligence, able to speak clearly enough and express emotions as mundane and extraordinary as the audience needs to identify them as people..... and then on the other hand there's machines, who even though they are on the large part very fucking dumb and prone to iterating the same behaviors, they have communities, social roles, FAMILIES even though they have no biology that sorts them into familial units in the first place.
Neither of them can age, neither are born through sexual reproduction, and when connected to their respective networks neither can really DIE, and this throws off the whole human thing of being born into families and growing from a child into an adult and potentially becoming the parent to a new child later, of having siblings you come into the world connected to, and of having family roles that are (usually) both innate and distinct -- a sibling might be older than you but that's different to a parent being older that you, right?
So machines have parents and siblings and uncles and aunts and family dynamics, but if they're not biological, then all child machines are adopted, that's simple enough. But they don't age. A child machine does not necessarily grow into an adult. They can stay children, even infants, forever, and their minds don't progress beyond that state even though there are other machines of greater maturity and intelligence and just mental age than the children, so being an adult is clearly possible, but it does not correlate with growing or getting to adulthood through linear change. How does that work? Are they born adults? Are they born parents?
I feel like this is pretty cleanly answered with Adam and Eve who are really like... communicative characters being machines that look and talk like the android characters. Android bodies and machine psyches or something... Anyway, you see them both be born within minutes of each other. Featureless, sexless, ageless, undifferentiated, basically in the world for nearly the exact same amount of time to gain experiences and maturity.
The next time you see them, Adam is the elder, he's more mature, smarter; a caretaker even if he's doing kind of a shit job at it, while Eve is concerningly dependent and childish, doing whatever he's told and just talking about baby things like he wants to play, he hates wearing clothes and eating dinner. Adam implies they've taken on physical sex at some point since they were last seen naked as well.
And they're not just acting like brothers either, there's something extremely off about these guys. It might be hard to identify at first because it's not really overtly stated, but Adam did technically give birth to Eve and is in that sense also his mother. He feeds him and clothes him and teaches him and even gave him a name, and their dynamic is all sorts of weird because they're multitasking mother and brother in the same relationship.
It stands to reason, then, that machines have a thing about taking on human roles, gender roles and familial roles and societal roles like knights and kings, and their minds and bodies shape around that role so that they can best fulfill it, not the other way around. The brothers were not born with genitals or any kind of gender presentation but they developed those as they took on that role of brothers, male siblings. Adam leans very androgynous and I think it's because he's got a female role as well. Eve stays immature because he's the little one, he's always going to be the little one as long as that's his role, even though they're the same size and the same age chronologically.
I'm not exactly sure where I'm going with this I just think it's kind of a brilliant take how this game considers one of the core facets of humanity to be how we find purpose in relation to each other and form identities in the contexts of social groups.
When Eve loses his brothermom, he loses the thing that was connecting him to his social roles and goes, shall we say, off the shits. And the same thing happens to 9S later because the YoRHa combat roles are the same kind of thing, if more externally assigned-at-birth -- his entire purpose was to support someone else.
These two are secondary, they're the rib, the support, they were made to be dependent and when severed from their special person it results in a catastrophic collapse of identity. They get decontextualised and struggle to find that footing again without devolving into destruction or self-destruction, which is not unlike what grief can do to a person anyway.
Another thing is that throughout the game you see machines of all levels of intelligence hurt themselves and kill themselves, and for a long chunk of the game I had assumed this was because they were still robots in the end and had some kind of self-destruct programming that was acting up. The final route flips this on its head and shows self-harm and fear to be horrifically human things, something expressed even in the characters that act the most realistically like people... because they act the most realistically like people.
NieR:Automata shows you the most painful emotions of grief and loss of identity and insists that these are very basic and natural and HUMAN responses to traumatic events, even if they make you feel like the entire world is collapsing -- it's that capacity for love and hurt that we have in common with all other people. Fucking phenomenal game, the more I think about this the more it makes me feel serene and connected to the world.
