In The Expanse, the first book, there’s a scene on the Canterbury where a belter who lost his arm moving ice is getting a robotic prosthetic. He scoffs at the possibility of getting the arm regrown using gel developed by the inner planets, saying that he’d rather have a belter made fake than anything from the inners. Someone then said there’s a period of neural adjustment where the arm doesn’t feel like yours, and this is great actually because they say that when you jerk off with it it’s like getting a handjob from someone else.
With all that in mind, it is good to see a robotic hand being able to undertake fast repetitive motions without harming human flesh.
