People worry a lot about losing knowledge — about "burned-down libraries".
Comparatively few people seem to worry about what happens if you take a billion books full of auto-generated, often-untrue junk text and *add* them all to the library.
In theory, nothing is lost. In reality, everything is lost, because nothing useful can now be found.
@tomw This has honestly been my primary concern with AI becoming increasingly sophisticated. Not just limited to libraries, any place where information is stored or communicated would be vulnerable to being completely flooded with garbage.
