Don't be a gonk an idiot, they're prosthetics. I appreciate that if I lose my arms I can replace them, but who WANTS to get cybernetics if they can help it? Advertising to the public would be unethical even if it is open source, you want to advertise this to doctors, and even then only within the existing niche. Cybernetics as a commonplace thing were never meant to be more than a 1980s action sci-fi Hollywood fever dream.
I get it. To a degree, we're living in a dystopia, a real one. It's entirely sane to say "the rich did this" and want them to suffer. It's sane to be bothered they're currently getting away with it. Doesn't mean people are stupid, it just means social Darwinism is no different than running civilization as if civilization never existed. The rich right now are generally competently evil, and unfortunately that is what capitalism enforces. "Market forces" and "supply and demand" are just a pretty way to describe "survival of the status quo" because the status quo has always been "ooh, babies are weak and delicious!" because that's how things work in the wild.
This is not the wild. This is not how things should be, regardless if that's "how it's always been". But this is a world where some stories come true. Miami 2017 was written and first sung long before 9/11, MegaMan Battle Network was right on the 00 Green, and Inception was onto something about dreams, if a story has already been written it isn't somehow magically made falsehood.
