Actually there are people that have looked into landfills that are
in the
100-200 years old range and they have found things in
an amazing state of
preservation. Some cases there were newspapers in the middle of the stack
that were as fresh as printed in appearance. Yet in another layer old
papers were completely composted. I'd suspect that old technology would
be found the same way, some just oxidized piles and others completly
intact.
Yes, I have heard about this on Discovery Channel. And they dug up
that landfill at New York and found was just grey sludge at the
bottom. But most of stuff they found was still readable and bit
discolored. There should be a better way to compost them...
Allow enough O2 there, it will decompose and oxidize better.
