Honestly that would make a good sci fi short story. What appears to be a well of knowledge created by an advanced but missing species that turns out to be nothing but well ordered gibberish.

Maybe it spreads to other civilizations that find it and accidentally incorporate it into their technology.

Or maybe they go to war over it and destroy themselves leaving whoever is left to find out that’s its cyber trash.
