Most likely They are not going to be allowed to rest at all. Especially western humanity is basically sanitizing the whole earth below them of human culture and history and storing it away in boxes and vaults, and ephemeral digital files of dubious quality, centralized for some Library of Alexandria or Dresden Bombing atrocity to totally erase all the centralized records of humanity.

No one seems to think of these types of things, especially in todays world where everything is digital and even in places like America there will be nothing left but rather uninteresting rubbish piles of plastic and other toxic remains left where stick and drywall houses and junky metal warehouses used to be.

There will be no silver lined sheathes of common soldiers, no coins of any kind, let alone gold ones, there will be no hidden manuscripts, not even charred scrolls that could be recovered with the use of AI. There will not even be any buildings and castles that stood the test of time for 1000 years, or any new pyramids because it rich and successful don’t build grand and permanent anythings. Humanity will effectively have not only left a huge hole in history starting in about the 1980s, but there won’t even be anything left to discover in the ground from the past the way we are going. And worst, even the digital history is clearly starting to come under attack with censorship and deletion and even the IP rules where corporations just get to delete what they dem you should no longer have.
