I think some of it will be preserved in ways we did not think about.

I was reading yesterday that most of Venise is built on Oak post submerged under water. It has not rotten yet… Apparently the sea water “petrified” the oak and is harder than mortar.

Maybe some of our work will be submerged with volcanic ash, ice, etc.. Who knows, in a few thousand years, maybe…
