Perhaps gold platters with a system much like LP records could contain information that could be retrieved with fairly simple efforts. The problems would include wars and thefts, the deliberate altering of facts, burglaries , and opposition by various governments. Also deciding what is fact and what is opinion in the original proposed data would cause endless strife. issues like who shot JFK or the qualities of current presidential candidates, would include all kinds of disagreements. Can you imagine such a disk that contained "elements within the US government, combined with the military, industrial complex, used resources within the Maffia to kill president John F. Kennedy." being acceptable to the US government?
