Digital immortality is impossible without solving so called identity problem, that is the solution of the problem will my copy be me, and if my copy is me, what level of informational loss is acceptable. This problem is not solved yet, but we are working on it, and our state of art knowledge on the topic is presented in our Identity map. The map is here.
Digital immortality is only Plan C in our plan to for Immortality, where plan A is life extension and plan B is cryonics. Full immortality map is here.
We hope to provide solutions of Identity problem as service in the future. If we can prove that there is no ontological identity, we will provide this prove. If some kind of identity exist we could provide a transfer mechanism.
