Don't be fooled–LLMs don't reason

    My pet theory is that there are different types of intelligence that have different pros and cons. Social/cultural, intuition, and structural.

    Structural is like step by step reasoning or math or raw compute.

    Intuition is statistical from repeated trial and error.

    And social is leaning on the wisdom of the crowds. So like high latitude countries where they eat fish for breakfast and get better health outcomes.

    So I believe that LLMs have stumbled upon a partial component of our social intelligence. Word distribution, ontologies, jargon, information theory (frequently used symbols should be short). We mutate the language that we speak to be useful to us based on the problems we face. To some extent being able to talk the talk means you can also walk the walk. At least partially.

    It's kind of shocking how far they can get, but at the same time it's kind of a surprise how far they don't. The existence of agentic harnesses is sort of an admission of defeat.

    While some might be fooled into thinking that they reason, everyone I've met isn't. As a software engineer I'm drowning in work. And if that's not an admission that this isn't a real intelligence then I don't know what is.

    But ultimately it looks like we've got all the individual components sorted. The old school 70s era stuff has a lot of the structural intelligence covered. The data science era of statistical ML has the intuition. And LLMs have the intelligence from our culture.

    Maybe there are more general or energy efficient or powerful or special purpose techniques out there. And maybe combining everything together requires some additional insight. Regardless it feels like moving forward to something better than our current AI landscape is plausible, albeit with a completely unknown level of effort.
