Hello, /sci/. I want to riddle you a a hypothetical question from area that's basically purely speculative sci-fi that has me thinking a lot. I suppose that's better than umptienth thread about vax and shit like that. I am not /sci/ head and I do not have any education in the field, so pardon my surface level understanding of subject matter.
This question is primarily related to consciousness and neurology. Supposing it was possible to clone human brain, do, more or less good "scan" of original brain's contents and implant it into the cloned one in order to, for instance, prolong osomeone's existence, we can still deduce that it doesn't really at face value, logically. Original person is still very much alive, and their consciousness is not the same as their clone. This dilemna was main theme of "SOMA" video game. Same thing regarding thought experiments focused on teleprotation- even if we were able to completely "deconstruct" someone and "reconstruct" at different spot in space, person that we "teleported" is very much dead, even as person being end result is continuity of them.
Now, human body is in continuous state of "shedding" old cells constituting it and replacing them with new ones. This leads to cycles between each body is basically wholly replaced, and aging is related to fact that, over time, our body loses ability to do this reliably enough, right?
If there was a way to craft artificial cells and their products (i.e. neurons) by man, and somehow , over time, do the same p[rocess, but replacing human brain's neurons with artificially made ones, slowly but surely, would end result of such process still be same continued consciousness and conversely, the same person? Would that make such eprson effectively immortal?
