This REALLY reminds me of how jealously cells guard their genomic DNA from interaction with nucleic acids out in the environment.
Most genetic information on Earth is malicious information, selfish replicators in the form of viruses or transposable elements or selfish elements. Things that subvert the signals within a cell for their own propagation and provide nothing productive that the cells care about. So cells jealously guard their own genomic DNA and have all kinds of checks to make sure that nothing other than that sequence gets used, and outside sequence does not get incorporated into it. ANY DNA in your cytplasm gets rapidly destroyed, double stranded RNA sets off your immune system like crazy, even RNA with sequence statistics that are not quite like that of your species can set off an inflammatory reaction, immune system cells seeing RNA inside them that is overly compact and optimized like viral RNA treat them as sources of antigen rather than self.
I cannot help but think we are living through the transformation of our non-brain-information sphere into a state like that of the genetic information sphere. Most material out there being meaningless for our purposes and us needing to jealously guard the provenance of information we use so as to not use bull, or worse, huge amounts of malicious information made to subvert us to the purposes of the powers that be that generate it.
Evolution makes parasites more reliably than anything else. How did we train text-generation systems? Basically, to mimic the written word on the page like a stick bug on a stick. They're like those beetles that live in ant colonies, sending out social signals that make the ants see them as offspring that have to be babied rather than parasites that don't contribute. They replicate the form while not being the thing that they have subverted the signals of being.
