The average life of a DVD is around 5 years, but then, you also have to consider, what's the average life of a DVD player, what's the average life of a TV, what's the average life of the generator to supply the power to them? Much of their history would become like Chinese whispers, the definition changing as it passed by word of mouth from Generation to Generation.
As for what you'd teach your kids, I'd suspect the primary objectives would be things like 'How to grow and hunt food, how to build a shelter, what plants not to eat' etc.
Edit: Oh, and time capsules would mean both an pre-assumption that the race was about to be wiped out, and the fact that one would be accessible.
hi,
if a manufactured CD/DVD is prefect store (right temperature, air moisture and no sun light), they can hold theoretical their data so 100 years.
but practical its imho so about 20 years, one reason is a fungus, who destroy the data layer.
a burned CD/DVD is really difficult to say, if the burner doesnt have the right strategie to burn the medium its unreadalbe after the burning or will become unreadable after a short time.
burned CD/DVD are not really reliable mediums for save backups of datas.
to the dickussion about records.
i FS had scientists find records of the ancient and bosh had find material, too.
the next thing is the knossos gates work stable since 8000 years without maintenance and still had engery, so i think the ancient technologie is really tough, if they survive so long after thiere creatures are gone.
and i believe that the records that the GTA and Bosh had find wasnt paintings on the wall.
so i guess that the GTVA can read records.
but if surviving ancient have the full knowdelage of their old empire?
mhh doesnt so easy to say.
we doesnt know how excatly they had storage thiere knowledge.
if we say, that they storage it like us today, central in great centren and libraries, then i think its the chance that the culture and the knowledge to a great part survive not so gread.
if the structure was more decentral, then the percents are higher and maybe some parts had it survive.
but i think that if there out ancicent then they not compare to the old ancicent.
i believe in that culture are many myth and saga`s are present of an old devil enemy and a great empire, that they destroyed, but not really are compare to the 8000 year old gone empire of the ancicent.
