On mobile so can’t really link decent links. But years ago I read a good fiction book by Stel Pavlou (Decipher) and there was a story in it about how symbols maintaining their meanings over generations was a pointless exercise but that creating a religion was the only way to do it. Belief systems etc. The example given was about radioactive waste being buried.

Pointless comment. The article just reminded me of the book.

Edit: I searched my kindle app. The book referenced the below.

https://en.wikipedia.org/wiki/Thomas_Sebeok

“In the early 1980s, Sebeok composed a report for the US Office of Nuclear Waste Management titled Communication Measures To Bridge Ten Millennia,[9] discussing solutions to the problem of nuclear semiotics, a system of signs aimed at warning future civilizations from entering geographic areas contaminated by nuclear waste.[10] The report proposed a "folkloric relay system" and the establishment of an "atomic priesthood" of physicists, anthropologists, semioticians to preserve the true nature of hazardous site.[11]”
