This just hit me as an interesting example of an analysis that can take all the available data into account and considered through all kinds of lenses, but without a key will never be interpreted correctly (this is assuming you can’t just google the phrase). It reminds me of the darmok episode of tng where the computer couldn’t interpret a foreign language because it was based on a history of shared memes
Aren’t all (or almost all) memes famous randomly though? No one expected a sort of doofy photo of a teen to be famous for years for having bad luck, for example.
