Don't be fooled–LLMs don't reason

      And a magician making a coin "disappear" doesn't mean that magic is real. I see no way we can call it thinking without a goal (other than computing the next token).

        This is the problem I have. People are built to be fooled by this stuff - to see something that's not there. Pareidolia but with language. It's such a compulsion that the people who build LLM's see that the same non thing there too.

        When I stumble around trying to explain my thinking though I invariably get hit with the response, Sure, but if it's functionally identical to a coin being magically pulled out your ear, what's the difference if it is or if it isn't? The only response I have is that when the coin doesn't appear you're going to be putting yourself way further behind the starting line then if you thought from the get go that there's no such thing as magic.

          I really like this metaphor, it hits home that just because you sense something is human-like doesn't make it so. We're wired to respond to those sorts of things.

          I had similar difficulties expressing my thoughts in an organized way. The video below from Richard Sutton (the father of Reinforcement Learning [which LLMs use extensively in training]), helped bring order and firm up some of my thoughts and theories.

          &gt;I invariably get hit with the response, Sure, but if it&#x27;s functionally identical to a coin being magically pulled out your ear, what&#x27;s the difference if it is or if it isn&#x27;t?

          Not to spoil the video, but it isn&#x27;t at all functionally equivalent. LLMs are an imperfect and somewhat randomized simulation of what the LLM thinks an average person might say in response to a question. Which is another way of saying, most people will on average get worse answers than if they worked on a problem themselves (but they will get that worse answer from the LLM comparatively quickly). Practical people respond to this positioning fairly well, and for others it still lands a bit since no one wants to think they&#x27;re below average. That said, I&#x27;m still working on my positioning a bit as well!
