I think it’s possible that there are some forms of digital immortality within 20-30 years but that for people living now it won’t be a one size fits all thing. There may always be some distinction between born bodies de-aging and getting upgrades and the idea of immortal digital consciousness’s being uploaded. It might be more like the transporter paradox, or just some transition some people take when they reach extreme old age. I think we’ll likely see plural consciousnesses emerge at a point too. The trend we see in the universe so far has been toward more complexity.
