Wow, thank you everyone for your replies, especially @kurapikasuki!
I feel that I should emphasize that I put "perfect" in quotation marks for a reason. The notion of there being some imaginary impeccable version of a human being that you should conform to at any cost deeply disgusts me, and I'd never advocate making such surgery the societal standard. If someone told me I should get my dysmelic hand "fixed" because it's not "perfect" I'd punch them to the moon and back. (You might be thinking "why did she star this thread in the first place then?" now. That's because it's such a minor issue compared what many others live with on a daily basis!)
And I do apologize if I'm spouting a load of bull here, I'd just rather do it here and now than in the comic, and instead feel more confident about the story.
(Oh look I figured out the quoting system)
This hit me especially hard, I'm sorry if I poured salt into an open wound. I'm very happy you're telling me this, because this is precisely the perspective that I'm lacking!
I have no intention of writing some dystopian story where advances in tech and bio have strengthened ableist discriminatory thinking. It's not even a big focus of the story, it's a crime/mystery one, it's just something I want to get right in the same way that Hollywood should learn writing female characters in movies completely unrelated to feminism, so that as many as possible can read it comfortably without feeling irritated by it being another failed representation.
So keeping that in mind, do I understand you correctly in that - if I do decide to integrate advanced prosthesis tech into the story - I should not present it as the "ultimate solution" (that sounds so much like Nazi thinking shudder) but as one option among many, with wheelchairs, crutches, mobility chairs etc. being among them, and that they are as much a valid option and actually are useful in everyday life in terms of accessibility? And in addition, going off your FMA comment (I love that series to bits) that I show the disadvantages and struggles of prosthesises as well? Arakawa put so much thought into automail, including even frostbite (Briggs) and burns (the desert), the dangers of not letting it heal properly, maintenance... It's part of why I love the series, but for me it's just because I love a well thought through story and so I was afraid to use it as reference.
Good thing you brought this up. As you maybe can tell, I didn't think this through very far, ahah. Thanks for the wakeup slap. As it was a thought that popped into my head literally the evening before I wrote this post, I never got to the point of thinking about the distinction between a cyborg and an amputee with a prosthesis. This also kind of answers my question about how a cyborg character comes across, which seems to be as an able-bodied person with robotics. I feel that it will make a huge difference in how I should present it depending on which road I choose to go: prosthesis, cybernetics, wheelchair... or everyone always gets off scot-free or with "just a flesh wound" (which really isn't an option, since this trope annoys me to no end). Basically, do I go FMA, Cyborg 009... or Bleach?
That being said, even the cyborgs in C009 need regular maintenance and have malfunctions, and their sense of self and identity is a central part of the story. Even there it's not a magical solution, it's even something that was imposed on them.
@shazzbaa You have some great points as well! Thank you for your post!
Yeah, this is a worry I have. I think they'd be introduced in the order character -> oh look they have mech -> background story where among other things the reason for it is explained, so I hope that would at least mean avoiding the "oh wow yes they're like me now! .... oh and they're not..." kind of disappointment. But as kura pointed out, showing the disadvantages makes a difference. If I show the struggles of the prosthesis, require them to have it taken off (and show it!), maintained etc., essentially not play it off as a perfect solution and remind the audience that this person isn't magically un-disabled, would I avoid that trope then?
It wouldn't be any problem at all to include amputees choosing not to have any surgery beyond the amputation itself. As for the second question, it made me think quite a bit, for which I thank you, and here's my answer: It doesn't have to look like a limb, it just needs to work like one, much like Edward Elric in FMA kind of does need two arms and legs or he'd be a sitting duck. I should note that the emotional aspect tied to losing a limb will be one part of the character arc.
Amen.
For real though, that's why I came here. I know that the people in this forum for the most part are level-headed and sensible. Dedicated forums sounds like a great idea too.
