Someone asked me today if our proposed technique, Aldehyde Stabilized Cryopreservation (ASC), would still allow for biological revival. This person wants their original self back rather than a perfect copy. I very strongly disagree that a functional copy of the brain would not be equivalent to the original, but I will not address that here.
Does ASC allow for biological revival? The answer is a resounding yes! The chance of biological revival is not the slightest bit reduced by the use of aldehyde. The reason is that there is other damage which is far more significant. The presence of some crosslinks is, by comparison, trivial to fix.
The only arguments that I have ever heard against this are that a much improved version of cryopreservation might be better than ASC. But that's not the question under discussion here. I also don't think I will ever need to debate that because I don't think it's possible to have a much improved version of cryopreservation without aldehyde.
