IMHO - making a static full copy of my current personality is useless to me. there is no immortality of myself, just copy of mine, and we already have that in a bit different fashion - kids (I would say that&#x27;s even better approach compared to 100% copy).<p>facing my copy, there wouldn&#x27;t be a reason to feel immortal - I would die anyway, and the other guy would continue to live. so immortality for me means preserving my own instance of me, anything else is just not there. it seems to me this would be much harder to implement compared to creating a copy, so this would be available much later, and who knows with what consequences.<p>this is not possible in our timelines, and frankly, I don&#x27;t mind. kids are good enough solution, and as previous generations made space for our, I will make some space for next ones, hoping they&#x27;ll get a bit closer to stars than we did. once we settle through Milky way, our extinction on short or medium time scale should be less probable compared to single-planet situation.
