Without a human analyzing the transcripts it's very difficult for the chat bots to know which inputs it's receiving are "good" or "better."
Even the idea of good language is subjective. We all know there is such a thing, but nearly everyone has different ideas of what this is.
However, if language is more integral than that. If language is more a facet of intelligence than a building block. If language is the structure of sentience, rather than something sentience leverages, then no, all the chat bots in the world won't help. We need something that can integrate more than just plain text embeddings of incredibly intricate and complex structures. We can't crack this code without a key.
My guess is that this latter scenario is the likely case.
