If you are a living organism with the capacity to tell misery or pain just hope that humans don’t find out you can make a product that nothing else an can. If you do end up I’m that situation, you will be turned into a biological machine that receives the minimum amount of necessities met as to not impact production.
I am unsure from what this is from, but I once read a story in which a form of healing magic exists. One requirement for it to work was that the person being healed needs to be OK with it. If someone tried to cure your paralyzed legs and you don’t want them to be “fixed” as you don’t view as an issue or being paralyzed is just part of how you are, then the magic can’t work on you.
