>>5271112Biotransferrence is not the most ideal method of immortality imo
Mostly because Biotransferrence explicitly results in the loss of the soul and other emotions. Which according to most necrons, really sucks. Talos might consider it as a last resort. This is why most of them are trying to reverse it and get (better) Organic bodies back but don't know how, or like Szera Illuminor and Orikan move forward and become beings of energy instead.
Human Technology is actually already capable of this, albeit the DAoT one. Antigonus was a techpriest murdered by the Dark Mechanicus, but he happened to be next to a DAoT server hub and uplinked his mechadendrite into it. The computer was able to copy and recreate his entire mind. After centuries of piecing himself back together, he became a Machine Spirit itself and was able to interact via machines.
I still consider both of these ideal because it leaves an uncomfortable question of whether Talos still has a soul. In the first case with necrons they explicitly do not, in the second I don't particularly see it any differently.
I think the best form of immortality is brain preservation, exactly like the Emperor or Mr House. Just keep our brain secured in the most secure place possible, with some backup brains to transfer into in case of emergency, and then work on extending our reach to interact with the outside universe in surrogate bodies and machinery. Maybe even remotely control our original host body. That is the best of all worlds.
I mean, if we're willing to move our brain from our head to our chest, what difference does it make if we just move our head a little further out of our body anyway! Think of it like getting bluetooth brain instead of wired spinal connection.
