General Discussion

There's nothing resembling intelligence, general or not, in any autocorrect implementation so far, including LLMs.

LLMs don't make mistakes. If you think they do, you're completely misunderstanding what LLMs are, how they work, and what they do (probably because of the aforementioned misinformation by LLM peddlers trying to equate them to intelligence, artificial or not).

LLMs simply give you the most statistically likely word to follow a given text. Then they do it again, adding the word they generated in the previous cycle to the text. That's all they do, they're excellent at it, and they don't make mistakes, the word they output will be the most statistically likely, regardless of whether it makes sense or not (though attempts by their peddlers to keep them politically correct might cause them to discard the first several most likely words, leaving them able to only output a significantly unlikely — but hopefully politically correct — one, which might seem like a mistake to the user).

You seem to be assuming that LLMs are trained on knowledge. They're not. They're trained on text. They have no idea what the text means (they don't even have anything to have ideas with), and they don't care (nor have more ability to care than a desk lamp).

They have a model of what words (meaning sequences of characters, not concepts with any actual meaning) may come after certain others, they push the input sequence of meaningless characters through that model, and out comes the most statistically likely meaningless sequence of characters to follow said text. That's all.

Paraphrasing Neil Gaiman, “LLMs don't produce information. They produce information shaped sentences.”

They produce the dessicated corpses of the texts they were fed, shredded and put back together, drained of any actual information but indistinguishable enough from texts containing actual information to give the illusion of also containing it.

They're great as an alternative to lorem ipsum, or possibly as speech generators for non quest critical NPCs in games, but they're extremely dangerous for anything else, especially the uses LLM peddlers are peddling them for.
