If the survival of the human brain is the only sign of what makes a human being, then by replacing other organs of the human body and retaining the human brain, can a human be immortal? What is the difference between human and natural person after human-machine transformation? Can they be in love? What will happen to the love of the eternal and the doomed?
If the combination of human and machine is only used to treat diseases, most people can probably accept it. If it is just for the pursuit of superpowers, or to live forever with the beloved robot, do you have the right to choose to become an immortal robot as well? One more question, if you need to pay a high cost to achieve the integration of human and machine, how to deal with the possible inequality (the rich become immortal machines and keep their brains forever, and the poor, like humans today, have to face inevitable death)?
Characters like Zapan fully illustrate the stupidity and ugliness of human beings. Humans are not worthy of eternal life and any superpowers endowed by machines, which can only lead to contradictions and fights, and even killing. Alita seems to have the perfect girl brain and just loves fighting. So, do you wish there were such perfect girls all over the place? Or there are good and bad girls in mass production, and who can control the conflict and trouble caused by bad girls (perfect killing machines)?
The film does not attempt to answer or even ask such questions. The natural person Hugo and the robot Alita fell in love. Hugo had to choose to become a robot because he was hunted down (the head was cut off by Alita, and then the doctor replaced it with a mechanical body), and finally fell to his death and parted with Alita.
