But you're assuming that it'll always ne validated by humans. I'd imagine that most validation (and subsequent processing, especially going forward) will be done on machines.
By comparison with reality. The initial LLMs had "reality" be "a training set of text", when ChatGPT came out everyone rapidly expanded into RLFH (reinforcement learning from human feedback), and now there's vision and text models the training and feedback is grounded on a much broader aspect of reality than just text.
