We have had successful cryonic restoration of brain tissue in rabbits? I believe, and have also had successful brain transplants of mice.<p>I easily figure in the next 100 years we will accept cloning as a replacement for death. Simply duplicate the body, and transfer the brain, maybe throw in some extra gray matter to replenish what is lost through aging. Of course &quot;throw in some extra gray matter&quot; sells the complexity a bit short, but we are definitely on track to accomplish it.<p>I anticipate never <i>having</i> a 130 year old body. I would just replace mine with a genetically enhanced one at 60, and start over from ~15 (or honestly whatever the earliest age to insert a brain is). Almost anyone should be able to raise the money in ~30 years to pay to have another clone grown.<p>And from there you can iterate a few generations on first generation tech until we can manipulate the living brain into being able to learn like you are five again, hopefully without the negative side effects present in current brains of that capacity.
