Yes I did read it all, like I said the title is a quite click baity. As far sharing data with people(or other lifeforms) 10k years from now,that is an entirely different problem than "How to store data forever". I'm not saying I have the answer to your title or the other problem, both good questions that I wish I did have answers to. I believe that the voyager team created a golden record as they faced a simmilar communication/interpretation issue. Another "out there" idea that might solve the problem would be attaching a transmitter to a comet with a regular and frequent orbit, possibly Halley's comet which returns every 75 years, it is a short enough duration that the technology should still be available to receive the data. The comet idea would work well in preventing future generations from corrupting the data. Eg history is written by the victors of war. Other than those ideas, short of creating a religion I cant see too many ways to store data forever and keep it useful and uncorrupted. Which is kind of too bad and "too good to be true too!" as per my original comment! ;)
