SPOILERS AHEAD:
What they made: A (slightly technophobic) very human and involentary cyborg fighting for humanity and letting the equally human anti-hero die to keep on fighting for the human race against digitalization and greedy other humans. Also: strange human trafficking sob-story.
What it was: The first cyborg without any human tissue remaining fighting for justice and falling in love with the genderless anti-hero who is first machine gaining conciousness. They fall in love, unite in death, are reborn as a child and are the first thing far beyond humanity: a human soul and AI hybrid, the first life-form beeing native to the physical and the digital world. Also a loveletter to technology.
