I think most &quot;believers&quot; in cryopreservation would agree that it&#x27;s a long shot.  Even if restoration is theoretically possible, a lot of things need to line up for it to actually happen for an individual.  But as you say, there&#x27;s a significant difference between unlikely and impossible (which I&#x27;m going to assume is what was meant by praying to Zeus).  The hard drive probably has rather better chances than the frozen brain though.
