I think discussions around this are ill-served by the &quot;upload&quot; metaphor, as it somewhat implies that the new brain, the original brain, and the uploading process are all largely separate things. It seems much more likely to me that the new brain will take the form of an augmentation that survives the death of the original brain. The personality would be &quot;uploaded&quot; not by deliberately sampling parameters to feed a model, but by the new brain organically (heh) becoming a component and embodiment of the existing personality. I&#x27;m sure this isn&#x27;t a new idea, but I don&#x27;t know what it&#x27;s called.
