What would the minimal digital representation of a human brain & by extension memories/personality look like?
I am not a subject matter expert. This is armchair speculation and conjecture, the actual reality of which I expect to be orders of magnitude more complicated than my ignorant model.
The minimal physical representation is obviously the brain itself, but to losslessly store every last bit of information —IE exact particle configurations— as accurately as it is possible to measure is both nigh-unto-impossible and likely unnecessary considering the moment-to-moment changes living causes to the particles, while “self” appears constant. So would the detailed information of cell positions and compositions be sufficient granularity? How practical would it be? I don’t know of any existing technology that is able to achieve the level of detail that would likely be required. MRI is very impressive, but while structure can be viewed (at least down to a 0.2mm resolution as of 2024-04-02), chemical composition cannot (as far as I know).
Do we know what the important variables are, and do we know what tolerances within which the hypothetical “Mind of Theseus” is still the same mind? (I suspect this is a philosophical question and the answer is fully subjective and we have no way of knowing.)

You might find my notes of interest.
Yes, thanks!
