Alright, lots of interesting answers, I wish to add my two cents with this comment:
If you ever ask a robot if it wants a human body, it'd tell you to go fuck yourself.
Has anyone here ever read/watched The Bicentennial Man?
Great book writen by my favorite author, Isaac Asimov, and amazing adaptation by Robin Williams.
It tells the story of a robot that wishes to become man, and throught his entire existence he slowly becomes more man over time, but humanity never reconizes him as a man because deep down, he's still a machine, he can't age so he can't die, all of his organs still work perfectly over 200 years of age.
This is where things split since the book and the movie have different answers to this dillema, I'll start with the book. On the book, Andrew, our protagonist, is owned (before he buys his freedom) by a family of lawyers, so it is through them that he achives his rights as a thinking machine, but after completing 150 years of age he's still referenced as "The century and a half machine" which makes him upset, so for the next 50 years of his life he fights in the court system to oficialy be reconized as a man, but everything that he does only bounces back, so in a moment of bewilderment he asks his lawyer "Why haven't I been reconized as a man yet? I have all the characteristics that make me one!" and his lawyer just smiles at him, sadden at his questioning and responds "Oh Andrew... You are trying to rationalize humans, but we do things that even ourselfs don't have an aswer for" and in that moment, some switch flipped on his brain, he knew what he had to do. He disapears for a few weeks before returning to the lawyer's office looking pale and twitchy, she asks him what happened, Andrew responds "I went to a doctor's office and asked them to perform a surgery on my brain, I wished to kill some of the protonic connections to my brain, essentially poisoning it and slowlly killing me in the process..." He realized that the difference between him and man was his imortality, so he took away the thing that made him imortal, his unaging brain. A month passes and he's on his death bed and he receives a call from the supreme court (I don't know the goverment organ so I might be wrong) and they wish to congratulate him on his 200th birthday, as "The Bicentennial Man", he did it, he finally got legaly reconized as a human, and a day later, he passes away from the poisoning of his own brain.
This book is a lot to take in, especially since I skiped a lot of context to use the ending as an example, but I used it as to make a point: why would a machine tell us to fuck off for asking if it wants to be human? If that statement is true, then the inverse is also true, if a machine asks the question "If you could, would you transfer your mind into a flesh body?" I'm sure there will be a machine that'll answer "If you ask a human if it wants a robot body, it'd tell you to go fuck yourself." Why? Well it all comes down to a deep psychological matter, we always want the ideal since we reconize the limitations of our bodies, so a machine body would be perfect, no? We can't say for sure (yet), since there isn't a single human in a machine body, so our points on it are pure speculation, but I'll say that it most likely would not be that cool, for starters: Our bodies regenerate small wounds and such, a machine can't do that "Oh but nano machines" they are not miracle workers, our cells regenerate tissue by exchanging nutrients to make fleshy substitutes, what will you exchange to create a steel like substance to the wound on your robot body? "Oh my body won't be made out of metal, maybe some carbon ligament"... So like a human's? I don't know man, your version of immortality sounds like being human with extra steps.
This is a really hard concept to translate into words, hell I had to rewrite this post 4 times before reaching this point, but I can say that the answer in my head is a lot more cathartic than what I'm trying to write here, but I want to wrap this up with a final message: Don't devalue your bodies, let alone yourself. I saw many comments about people having disabilities and such, and for them I'm sorry, while I don't understand the desier to switch bodies, I can respect the decision to move on to a healthier alternative, and for the ones wanting to "be a anime girl"... You might have gender dysphoria, and if so, start doing therapy to figure somethings out, have a psychiatrist that you trust, and if everything points to being a trans woman, I hope your transition goes well. If you don't have gender dysphoria and still wishes to be a anime girl for the funsies, why? All these comments made me upset, not because of the varying levels of doomerisims, but because people are so fast to throw their well being away for a "quick fix" so let me tell you something, and you WILL listen to me! Love your body, love yourself, and love this world, it's far from perfect but you are here, WE are here, and we enjoy bits and pixels on a screen for fun, and sometimes like to talk about our own mortality, but ultimately we are here to live, the highs and the lows. My dad always said this "The same way all happiness is fleeting, no suffering is eternal."
Please take care of yourselfs, I love you ? (and sorry for the long ass text)
