>>10140152>>10138824Fundamentally, there needs to be "bidirectional" thought for any transfer in order to preserve ego continuity. If we imagine a mind as like water or some fluid, and the brain as a vessel for it, then just "pouring" the mind into a new vessel doesn't preserve continuity; the new mind in the new vessel can't communicate back to old mind in the old vessel.
However, if we consider simply connecting the two vessels and siphoning the mind from one to the other (at whatever speed) while the new mind can talk to the old mind as the latter is transferred to the former, then continuity is maintained and death does not occur.
There are two methods to achieve this, the moravec and the Mind Outsourcing one:
Utilizing external hardware and software connected directly and indirectly to the user's brain to allow a slow transfer of consciousness out of the biological substrate and into external databases.
This technology could theoretically allow the user to "outsource" much of one's mentality and memory storage to external substrates which were separate from the sophont's own brain, until finally most of the sophont's thoughts, perceptions, memories, identity, etc. take place outside and away from the mass of grey matter the sophont initially came equipped with. The external hardware which gradually comes to hold more and more of the individual's personality is known as the exocortex, while the software which runs on this equipment is known as the Exoself. It is possible to transfer bi-directionally most of a biont's extended consciousness by this method, since many of the most competent processes of intellect now occur outside the skull in the exocortex.
The problem would be that you would have to revist every singular part of your mind in a total manner, such a task can only be accomplished if you have total self-awareness (autosentience).
