>>11519534Plan A seems to already be underway, with more research needing to be done. I advise fixating research there, for now. Plan C, at least for the body and not the brain will be doable once we figure out good interfaces between the nervous system and artificial limbs, and ways to inject nutrients into the nervous system without a digestive tract.
As far as the brain though, I think consciousness is an important question. The safest bet is to biologically immortalize the brain, robotize the body. However, this leaves the brain weak. The next idea would be to piecewise replace the brain with machine so that consciousness would be continued from bio to robo, making the brain more resilient to damage. This seems to be a long ways off, maybe 100-150 years given the complexity of the brain, but bio immortality can let us get there. Also useful in being radiation resilient for space travel. The next thing is cryonics. At low enough temperature, chemical processes don't occur. Consciousness would be empty or frozen in state, functional after. I don't presume qualia would be swapped to another space though, guessing based on those in low-activity comas. How are the latter different from disassembly and reassembly?
Last up is digital immortality. Going with the theme of continuity, "uploading" to a cloud does not preserve it, it just creates a copy. Do copies share qualia? Regardless, I see one way to create non-localized continuity: electromagnetic interfacing. If we have a secondary (or tertiary, etc) mechanical brain that can feed stimulus to the initial robotized brain, and the initial able to control the secondary, there should be no "preference." They perceive eachother, and perception should be able to flow from one to the other. With a large number of copied brains, we have backups to survive if the initial gets damaged, decentralizing sentience from one to the others and allowing it to move on the active one's command if destruction is near
