I didn't say it wasn't amazing nor that it couldn't be a component in a larger solution but I don't think LLMs work like our brains and I think the current trend of more tokens/parameters/training LLMs is a dead-end. They're simulating the language area of human brains, sure, but there's no reasoning or understanding in an LLM.
In most cases, the responses from well-trained models are great, but you can pretty easily see the cracks when you spend extended time with them on a topic. You'll start to get oddly inconsistent answers the longer the conversation goes and the more branches you take. The best fit line (it's a crude metaphor, but I don't think it's wrong) starts fitting less and less well until the conversation completely falls apart. That's generally called "hallucination" but I'm not a fan of that because it implies a lot about the model that isn't really true. Y
You may have already read this, but if you haven't: Steven Wolfram wrote a great overview of how GPT works that isn't too technical. There's also a great sci-fi novel from 2006 called Blindsight that explores the way facsimiles of intelligence can be had without consciousness or even understanding and I've found it to be a really interesting way to think about LLMs.
It's possible to build a really good Chinese room that can pass the Turing test, and I think LLMs are exactly that. More tokens/parameters/training aren't going to change that, they'll just make them better Chinese rooms.
Thanks, I'll check those out. The entire point of your comment was that llm is a dead end. The branching as you call it is just more parameters which approach, in lower token models a collapse. Which is why more tokens and larger context does improve accuracy and why it does make sense to increase them. LLMs have also proven to in some cases have what you call reason and what many call reason but which is not a good word for the error. Larger models provide a way to stimulate the world which in turn gives us access to the sensing mechanism of our brain, which is to stimulate and then attend to disparages between the simulation and actual. This in turn gives access to action which unfortunately is not very well understood. Simulation, or prediction, is what our brains constantly do to be able to react and adapt to the world without massive timing failure and massive energy cost, for instance consider driving where you focus on unusual sensing and let action be an extension of purpose by just allowing constant prediction to happen where your muscles have already prepared to commit even precise movements due to enough practice with your "model" of how wheel and foot apply to the vehicle.
*Simulate, not stimulate lol
