It's not weird, it's just not possible right now. They can barely make functioning prosthetic hands. I'd give it 50 years to get even a fraction of what it is in fiction. I hope I live to see it in my lifetime, though. Even just to see it would be kinda cool.
I think it's potentially bad depending on what your concept of a soul is. I follow Plotinus' idea that the soul is interwoven with the body, and transhumanism creates a sort of Ship of Theseus issue where, is it still you or your body if you were to replace every one of your parts with robotic prosthetics? I know that's a very gay and overdone question, but still. I would say the spirit is likely closest to the mind, so if you retain your mind (not your brain, but your consciousness and self awareness), you are still with your own spirit. It cannot be diminished. One cannot say that a man who has lost his arm or even half of his body has less of a soul than a normal person.
However, one is close to God by participation in Being. If you no longer have to shit, are no longer susceptible to disease or even just natural processes of your own body, are you still participating in Being? Are you still able to know divinity? You could take it the complete opposite direction, too. According to Ennead 1.4 (or maybe 1.5?), Plotinus explains that it is not wrong to attend to one's own material circumstances if they detract from their ability to contemplate The One. Transhumanism, that is, relieving yourself of having to experience physical ailments and evils, could be considered the farthest extrapolation of this concept. By defying any ailment, even age, that would keep you from henosis, transhumanism could, in fact, be the most extreme act of reverence.
I think a lot of people are quick to call it demonic or evil because it is a rejection of the God-given body, but that's a very Christian idea to begin with. The greatest philosophers in history have all rejected the body insofar as they were able.
