With the tech billionaires obsessed with immortality and the very real prospect of them reanimating their disembodied heads frozen in a jar, modern revolution should leave nothing to chance and evolve from the guillotines of the French Revolution to something a little more permanent like a tree shredder.
It is not a very real prospect it is a grift, you could get enough genetic material to clone the gullible idiot but archiving memory, personality and brain structure is not even close, the frozen brain is just jam. And even if it were not there is no way to return that information. Jam, its all just jam.
