I did in my comment, just using different language. Replace "AI" or "simulator" or whatever with "God" or "god" or whatever and you get typical spiritual afterlife/resurrection claims. (Additionally, "spirit"/"spiritual" can be translated as "computation"/"computational" in some contexts.)
What looks, at the moment, as the most feasible technology that can grant us immortality (e.g., mind uploading, cryonics)?
I posed this question to a fellow transhumanist and he argued that cryonics is the answer, but I failed to grasp his explanation. Besides, I am still struggling to learn the basics of science and transhumanism, so it would be great if you could shed some light on my question.
