Why can't that physical medium be GPUs and RAM? And temperature sensors and cameras? What's special about our meat that it's our "body" in the way a computer is not the body of an AI?
I don't think the point being argued can be true without some incredibly contrived, human centric definitions of "body".
Would you be "you" in a different body?
To claim otherwise would mean anyone who's gotten a transplant or amputation is no longer themselves.
The experience of “you” is just your specific memories and world model, continuously updated with sensory input.
If another body “runs” the same exact pattern, that is you. Theres no link and nothing was transferred; the pattern of thoughts and memories is all “you” ever was.
Same as playing the same song on two different speakers. Nobody asks what links the song across them; it’s the same song wherever it’s played. You’re just a far more complicated pattern on a far more complicated speaker.
You might ask, “but why am I this pattern?” Because this is the specific pattern modeling itself from the inside in asking that question.
And my intuition is that no, you can’t, they are two aspects of the same reality.
If "I" am in a different body, then what makes that "me" who's in a different body?
