It's an interesting idea. They still debate about some archealogical finds, when were they actually constructed and why, also they find some old interesting tech that seems advanced for the times. Hindsight is often speculative.@ipman Would be fun to be a fly on the wall when they start digging in the sand and find archeological finds that are props from the Cleopatra movie and similar. Maybe they find something from the Terminator movie and go: Wow!, they were actually pretty advanced, wonder what happened...
But I think in a few hundred years all humans will have an Elon Musk style Neuralink device and have instant access to all information.
At present I think we do mix reality and fiction when we remember. So if we think about the Vietnam war for example, we remember some of the facts, maybe how it started and finished, but our minds add films like Born on the 4th July, Apocalypse Now, etc into the mix.
