“Take very high resolution scans of brain structure to characterise how someone’s neurons work, recreate it in a digital format then put it in another robotic, virtual or biological body.”
This isn't preserving, it's copying. A copy of your brain/personality/you... isn't you... it's a copy. It's a cassette tape playing back the radio you recorded onto it.
It's really kind of odd that people talk about brain transplants, or living forever, and then talk about uploading your mind to the cloud or swapping someone else's healthy brain into your healthy body, or scanning your brain and recreating it, and make it sound like it is going to help you to live forever. If my brain is scanned and uploaded to the cloud, a copy of me would live on forever, but me, literally, me, will still deteriorate and die, then rot away into nothingness. My mind, my personality, my essence, me, will not live forever under any of these solutions. I'll die. A copy of me, a point in time snapshot of who I was when it was taken, will continue on, with my memories, mimicking who I was. That gives me no comfort at all. I don't care if a copy of me lives on forever if I still die. That's not immortality, not for me personally, not if I die.
