1. The process to revive a person after freezing does not exist. Current speculations about how it would work are so mired and poisoned by wishful thinking that it is essentially impossible to know whether it will ever exist.
2. Even if the process will some day exist, it will be too late for you if you were not frozen correctly. It’s like writing a zip/compress program and speculating that someone in the future might one day invent unzip/uncompress – if unzip or uncompress eventually does appear, it is extremely likely to show bugs in the implementation and/or specification of the original zip or compress program, making all data previously thought to be “compressed” instead utterly corrupt and worthless.
3. The incentives are all wrong for the actual truth to surface. The incentive for a company in this business is to imply that the science is (or will soon be) much farther along than it currently is, and a customer has the incentive to believe this, since the alternative is death. To paraphrase: It is difficult to get someone to understand something, when their life depends upon them not understanding it.
