What exactly is a false minoshiro in Shinsekai Yori?
The false Minoshiro (lit. ミノシロモドキ, minoshiro-modoki, monoshiro-mimic) they encounter identifies itself as "Panasonic Automotive Archive, Autonomous Evolution, version SE-778H Lambda." About 890 petabytes of data is stored within it using holographic memory; this includes all 38,242,506 volumes published in Japan since 2129 AD and 671,630 reference books in other languages. The novel describes it to be a sort of flying transportation and search engine. 

Because it allows easy access to the large cache of information, the intellectual elite are afraid that this forbidden knowledge might get leaked to the general public through it, and have made it a taboo to touch or even speak to it.
