Unfortunately there are things like bit rot
And some serious obsolescence issues that have already cropped up. Along with more routine physical deteriation of storage media. I think that our assumptions about longevity of our information are a bit optimistic. There’s already plenty that’s inaccessible or lost.
But basic knowledge won’t be going anywhere. We’re often stuck on prehistoric creatures because no-one was around to record anything. But there wasn’t a tremendous amount of confusion about how a mammoth or mastodon was put together. Even before we started finding bodies. Because people drew and painted that shit. And we know an awful lot about the dodo and other recent extinctions. I doubt anyone is going to be confused about turtles. We’ve spent a lot of time on turtles. Even if all that survives in detail is Teenage Mutant Ninja Turtles it’ll be clean they pulled into their shells rather than stepping out of them.
