Uh, I think this should be a thing considering we have LLMs training other LLMs. so we end up with this BARF loop.
There is an actual interesting question here if BARF loops can create new synthetic knowledge, or if humans need to be the 'spark of novelty' in that loop to drive it to new knowledge.
There's another thread running at the moment about BARF degrading the machine's performance. I don't have enough information to be confident, but it sounded plausible and likely.
And the humans are trillions of tiny nanobots (after a there was a "Grey Goo" event billions of years ago) that formed a hivemind that isn't even aware of all its own parts. :P
We have achieved complete ouroboros.
