I wonder how you ever could "upload" a consciousness without Ship-of-Theseusing a Brain.
Cyberpunk2077 also has this "upload vs copy" issue, but doesn't actually make you think about it too hard.
That's what I've always thought more or less, to have a chance you would need a method where mental processing starts to be shared in both, then transfers more and more to the inorganic platform till it's 100% and the organic isn't working anymore.
The animated series Pantheon has a scene depicting exactly this, and it's one of the most disturbing things I've ever seen.
Edit: Here is the scene in question. It's explained he has to be awake during the procedure because the remaining parts of his brain need to continue functioning in tandem with the parts that have already been scanned.
Interesting but I would argue that's actually still a destructive copy process. "Old Man's War" did a good job of what I'm talking about, it was body to clone body but the principal was similar and at the halfway point the person was experiencing existence in both bodies at once, seeing both bodies from the perspective of each other until the transfer completed and they were in the new body and the old slumped over.
That also reminds me of this scene from Invincible where during the copying process their experiences are sort of "blended" making them see from both bodies at once, only here they both live and are separate afterwards.
Edit: is it obvious how much of a sci-fi geek I am lol
Yeah, like replacing individual braincells with more durable mechanisms. Idk, maybe they would be cellular as well. ..that makes me wonder, maybe it is possible to transfer consciousness even with traditional biological mechanism?
You would have to functionally duplicate the exact structure of the brain or its consciousness while having the duplication mechanism destroy the thing it was reading at almost exactly the same time. And even then, that's not really solving the issue.
I don't see an issue with that. A prolonged brain surgery that meticulously replaces each part with a mechanical equivalent in sequence. Could probably remain conscious the whole time.
Yeah, but it's still a Ship of Theseus problem. If you have a ship and replace every single board or plank with a different one, piece by piece, is it still the same ship or a completely different one, albeit an exact replica of the original. It's important because of philosophical ideas around the existence of the soul and authenticity of the individual and a bunch of other thought-experimenty stuff.
I think so long as you maintain consciousness that issue is fairly null in this particular circumstance. There's lots of tolerance for changes in thought while maintaining the same self, see many brain damage victims. So long as there is minimal change in personality, there are lots of other circumstances that have a stronger case for killing one person and having a new person replace them due to change of consciousness, imo, I don't think most people would consider a brain damaged person killed and replaced by a new consciousness, or a drug addiction with radically altered brain chemistry, etc.
Not necessary. Imagine you begin suffering Alzheimer. And the artificial neurons are making a copy of your brain. Once a neuron stops working the backup one replaces it. Your mind, if it worked, could see the new neuron as part of the same brain and work with it seamlessly.
