You are best off thinking of LLMs as highly advanced auto correct. They don't know what words mean. When they output a response to your question the only process that occurred was "which words are most likely to come next".

And we all know how often auto correct is wrong

Yep. Been having trouble with mine recently, it's managed to learn my typos and it's getting quite frustrating

That's only true on a very basic level, I understand that Turings maths is complex and unintuitive even more so than calculus but it's a very established fact that relatively simple mathematical operations can have emergent properties when they interact to have far more complexity than initially expected.

The same way the giraffe gets its spots the same way all the hardware of our brain is built, a strand of code is converted into physical structures that interact and result in more complex behaviours - the actual reality is just math, and that math is almost entirely just probability when you get down to it. We're all just next word guessing machines.

We don't guess words like a Markov chain instead use a rather complex token system in our brain which then gets converted to words, LLMs do this too - that's how they can learn about a subject in one language then explain it in another.

Calling an LLM predictive text is a fundamental misunderstanding of reality, it's somewhat true on a technical level but only when you understand that predicting the next word can be a hugely complex operation which is the fundamental math behind all human thought also.

Plus they're not really just predicting one word ahead anymore, they do structured generation much like how image generators do - first they get the higher level principles to a valid state then propagate down into structure and form before making word and grammar choices. You can manually change values in the different layers and see the output change, exploring the latent space like this makes it clear that it's not simply guessing the next word but guessing the next word which will best fit into a required structure to express a desired point - I don't know how other people are coming up with sentences but that feels a lot like what I do

LLMs don't "learn" they literally don't have the capacity to "learn". We train them on an insane amount of text and then the LLMs job is to produce output that looks like that text. That's why when you attempt to correct it nothing happens. It can't learn, it doesn't have the capacity to.

Humans aren't "word guessing machines". Humans produce language with intent and meaning. This is why you and I can communicate. We use language to represent things. When I say "Tree" you know what that is because it's the word we use to describe an object we all know about. LLMs don't know what a tree is. They can use "tree" in a sentence correctly but they don't know what it means. They can even translate it to another language but they still don't know what "tree" means. What they know is generating text that looks like what they were trained on.
