Cryonics is useful for preserving your body until a method for immortality is developed. It is not, on it's own such a method.
If you die now, cryonics is the only method available to give you a chance at immortality.
Cryonics is either not an answer, or the only answer, depending on what exactly you mean by the question.
More importantly, cryonics is useful for preserving information. (Specifically, the information stored by your brain.) Not all of the information that your body contains is critical, so just storing your spinal cord + brain is quite a bit better than nothing. (And cheaper.) Storing your arms, legs, and other extremities may not be necessary.
(This is one place where the practical reasoning around cryonics hits ugh fields...)
Small tissue cryonics has been more advanced than whole-body. This may not be the case anymore, but certainly was say four years ago. S...
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.
