It's an illusion. People think that because the language model puts words into sequences like we do, there must be something there. But we know for a fact that it is just word associations. It is fundamentally just predicting the most likely next word and generating it.

If it helps, we have something akin to an LLM inside our brain, and it does the same limited task. Our brains have distinct centres that do all sorts of recognition and generative tasks, including images, sounds and languge. We've made neural networks that do these tasks too, but the difference is that we have a unifying structure that we call "consciousness" that is able to grasp context, and is able to loopback the different centres into one another to achieve all sorts of varied results.

So we get our internal LLM to sequence words, one word after another, then we loop back those words via the language recognition centre into the context engine, so it can check if the words match the message it intended to create, it checks them against its internal model of the world. If there's a mismatch, it might ask for different words till it sees the message it wanted to see. This can all be done very fast, and we're barely aware of it. Or, if it's feeling lazy today, it might just blurt out the first sentence that sprang to mind and it won't make sense, and we might call that a brain fart.

Back in the 80s "automatic writing" took off, which was essentially people tapping into this internal LLM and just letting the words flow out without editing. It was nonesense, but it had this uncanny resemblance to human language, and people thought they were contacting ghosts, because obviously there has to be something there, right? But it's not, it's just that it sounds like people.

These LLMs only produce text forwards, they have no ability to create a sentence, then examine that sentence and see if it matches some internal model of the world. They have no capacity for context. That's why any question involving A inside B trips them up, because that is fundamentally a question about context. "How many Ws in the sentence "Howard likes strawberries" is a question about context, that's why they screw it up.

I don't think you solve that without creating a real intelligence, because a context engine would necessarily be able to expand its own context arbitrarily. I think allowing an LLM to read its own words back and do some sort of check for fidelity might be one way to bootstrap a context engine into existence, because that check would require it to begin to build an internal model of the world. I suspect the processing power and insights required for that are beyond us for now.
