This leads to a well-documented phenomenon known as model collapse. You know how if you blur and sharpen an image repeatedly you eventually end up with just a rectangle of creepy, wormy spaghetti lines? You lose information on each blur, and then ask it to reconstitute the image with less information on each sharpen, until there's nothing recognizable left.

Training a model is like the blur and generating from that model is like the sharpen. Repeat enough times and enough information is lost that you're just left with "wormy spaghetti lines"—in an LLM's case, meaningless gibberish that actually pretty closely resembles the glitchy stuff said by the cores that fall off GLaDOS in Portal. I dunno, you read the paper and be the judge:

Of course you may be talking about the human aspect of this. Gods willing, we'll realize that our LLMs are spewing gibberish and think twice about putting them in all the things, all the time. But the scenario I fear isn't Idiocracy—it's worse: a community of humans who treat the gibberish as sacred writ, Zardoz style.
