You might enjoy Vernor Vinge's Zones of Thought series. The recurring protagonist-ish character, Pham Nuwen, decides to become a "programmer archaeologist" - the most lucrative job in the universe and also the job that's considered to maintain the fabric of civilization itself :)
For more in this line, check out Newton's Wake, by Ken MacLeod. In that book, there are combat archeologists: people who go places where a singularity blew through, leaving all manner of post-singularity technology lying around, and they have to make sense of it to use them or steal ideas from them, only they have to do this in the midst of armed conflict over ownership of those things.
I think there a strong case of prescience there. It is not unreasonable that we will have systems whose time tracks to the beginning of the computing epoch in 1970 long after we forget what 1970 was (assuming we don't kill ourselves first). Just think of all the layers above that today and add a few thousand years.
