Suppose it's the year 2040 - What are the chances of successfully reviving a cryopreserved human body and curing the disease that killed him or her?

From Wikipedia: Cryonics is the low-temperature preservation of humans and animals that can no longer be sustained by contemporary medicine until resuscitation may be possible in the future. Currently, human cryopreservation is not reversible, which means that it is not currently possible to bring people out of cryopreservation. The rationale for cryonics is that people who are considered dead by the current legal or medical definitions will not necessarily be dead by future standards.

A related question would be: Suppose cryonics becomes more affordable, would you consider buying a contract?

While cryonics is sometimes suspected of being greatly profitable, the high expenses of doing cryonics are well documented. The expenses are comparable to major transplant surgeries. The largest single expense, especially for whole body cases, is the money that must be set aside to generate interest to pay for maintenance in perpetuity.

The most common method of paying for cryonics is life insurance, which spreads the cost over many years. Cryonics advocates are quick to point out that such insurance is especially affordable for young people. It has been claimed that cryonics is “affordable for the vast majority” of people in the industrialized world who really want it and plan for it in advance.

What is your opinion?
