  • Hey again! First of all, thank you for continuing to engage with me in good faith and for your detailed replies. We may differ in our opinions on the topic but I’m glad that we are able to have a constructive and friendly discussion nonetheless :)

    I agree with you that LLMs are bad at providing citations. Similarly they are bad at providing urls, id numbers, titles, and many other things that require high accuracy memorization. I don’t necessarily agree that this is a definite proof of their incapability to understand.

    In my view, LLMs are always in an “exam mode”. That is to say, due to the way they are trained, they have to provide answers even if they don’t know them. This is similar to how students act when they are taking an exam - they make up facts not because they’re incapable of understanding the question, but because it’s more beneficial for them to provide a partially wrong answer than no answer at all.

    I’m also not taking a definitive position on whether or not LLMs have capability to understand (IMO that’s pure semantics). I am pushing back against the recently widespread idea that they provably don’t. I think LLMs have some tasks that they are very capable at and some that they are not. It’s disingenuous and possibly even dangerous to downplay a powerful technology under a pretense that it doesn’t fit some very narrow and subjective definition of a word.

    And this is unfortunately what I often see here, on other lemmy instances, and on reddit - people not only redefining what “understand”, “reason”, or “think” means so that generative AI falls outside of it, but then using this self-proclaimed classification to argue that they aren’t capable of something else entirely. A car doesn’t lose its ability to move if I classify it as a type of chair. A bomb doesn’t stop being dangerous if I redefine what it means to explode.

    Do you think an LLM understands the idea of truth?

    I don’t think it’s impossible. You can give ChatGPT a true statement, instruct it to lie to you about it, and it will do it. You can then ask it to point out which part of its statement was a lie, and it will do it. You can interrogate it in numerous ways that don’t require exact memorization of niche subjects and it will generally produce an output that, to me, is consistent with the idea that it understands what truth is.

    Let me also ask you a counter question: do you think a flat-earther understands the idea of truth? After all, they will blatantly hallucinate incorrect information about the Earth’s shape and related topics. They might even tell you internally inconsistent statements or change their mind upon further questioning. And yet I don’t think this proves that they have no understanding about what truth is, they just don’t recognize some facts as true.


  • In my sense of “understanding” it’s actually knowing the content and context of something, being able to actually subject it to analysis and explain it accurately and completely.

    This is something that sufficiently large LLMs like ChatGPT can do pretty much as well as non-expert people on a given topic. Sometimes better.

    This definition is also very knowledge dependent. You can find a lot of people that would not meet this criteria, especially if the subject they’d have to explain is arbitrary and not up to them.

    Can you prove otherwise?

    You can ask it to write a poem or a song on some random esoteric topic. You can ask it to play DnD with you. You can instruct it to write something more concisely, or more verbosely. You can tell it to write in specific tone. You can ask follow-up questions and receive answers. This is not something that I would expect of a system fundamentally incapable of any understanding whatsoever.

    But let me reverse this question. Can you prove that humans are capable of understanding? What test can you posit that every English-speaking human would pass and every LLM would fail, that would prove that LLMs are not capable of understanding while humans are?



  • As I understand it, most LLM are almost literally the Chinese rooms thought experiment.

    Chinese room is not what you think it is.

    Searle’s argument is that a computer program cannot ever understand anything, even if it’s a 1:1 simulation of an actual human brain with all capabilities of one. He argues that understanding and consciousness are not emergent properties of a sufficiently intelligent system, but are instead inherent properties of biological brains.

    “Brain is magic” basically.











  • I don’t think that anyone would argue that the general public can even solve a mathematical matrix, much less that they can only comprehend a stool based on going down a row in a matrix to get the mathematical similarity between a stool, a chair, a bench, a floor, and a cat.

    LLMs rely on billions of precise calculations and yet they perform poorly when tasked with calculating numbers. Just because we don’t calculate anything consciously to get a meaning of a word doesn’t mean that no calculations are actually done as part of our thinking process.

    What’s your definition of “the actual meaning of the concept represented by a word”? How would you differentiate a system that truly understands the meaning of a word vs a system that merely mimics this understanding?




  • I don’t think your assumption holds. Corporations are not, as a rule, incompetent - in fact, they tend to be really competent at squeezing profit out of anything. They are misaligned, which is much more dangerous.

    I think the more likely scenario is also more grim:

    AI actually does continue to advance and gets better and better displacing more and more jobs. It doesn’t happen instantly so barely anything gets done. Some half-assed regulations are attempted but predictably end up either not doing anything, postponing the inevitable by a small amount of time, or causing more damage than doing nothing would. Corporations grow in power, build their own autonomous armies, and exert pressure on governments to leave them unregulated. Eventually all resources are managed by and for few rich assholes, while the rest of the world tries to survive without angering them.
    If we’re unlucky, some of those corporations end up being managed by a maximizer AGI with no human supervision and then the Earth pretty much becomes an abstract game with a scoreboard, where money (or whatever is the equivalent) is the score.

    Limitations of human body act as an important balancing factor in keeping democracies from collapsing. No human can rule a nation alone - they need armies and workers. Intellectual work is especially important (unless you have some other source of income to outsource it), but it requires good living conditions to develop and sustain. Once intellectual work is automated, infrastructure like schools, roads, hospitals, housing cease to be important for the rulers - they can give those to the army as a reward and make the rest of the population do manual work. Then if manual work and policing through force become automated, there is no need even for those slivers of decency.
    Once a single human can rule a nation, there is enough rich psychopaths for one of them to attempt it.

    There are also other AI-related pitfalls that humanity may fall into in the meantime - automated terrorism (e.g. swarms of autonomous small drones with explosive charges using face recognition to target entire ideologies by tracking social media), misaligned AGI going rogue (e.g. the famous paperclip maximizer, although probably not exactly this scenario), collapse of the internet due to propaganda bots using next-gen generative AI… I’m sure there’s more.


  • I’d honestly go one step further and say that the problem cannot be fully solved period.

    There are limited uses for voice cloning: commercial (voice acting), malicious (impersonation), accessibility (TTS readers), and entertainment (porn, non-commercial voice acting, etc.).

    Out of all of these only commercial uses can really be regulated away as corporations tend to be risk averse. Accessibility use is mostly not an issue since it usually doesn’t matter whose voice is being used as long as it’s clear and understandable. Then there’s entertainment. This one is both the most visible and arguably the least likely to disappear. Long story short, convincing enough voice cloning is easy - there are cutting-edge projects for it on github, written by a single person and trained on a single PC, capable of being run locally on average hardware. People are going to keep using it just like they were using photoshop to swap faces and manual audio editing software to mimic voices in the past. We’re probably better off just accepting that this usage is here to stay.

    And lastly, malicious usage - in courts, in scam calls, in defamation campaigns, etc. There’s strong incentive for malicious actors to develop and improve these technologies. We should absolutely try to find a way to limit its usage, but this will be eternal cat and mouse game. Our best bet is to minimize how much we trust voice recordings as a society and, for legal stuff, developing some kind of cryptographic signature that would confirm whether or not the recording was taken using a certified device - these are bound to be tampered with, especially in high profile cases, but should hopefully somewhat limit the damage.



  • GPT3 is pretty bad at it compared to alternatives (although it’s hard to compete with calculators on that field), but if it was just repeating after the training dataset it would be way worse. From the study I’ve linked in my other comment (https://arxiv.org/pdf/2005.14165.pdf):

    On addition and subtraction, GPT-3 displays strong proficiency when the number of digits is small, achieving 100% accuracy on 2 digit addition, 98.9% at 2 digit subtraction, 80.2% at 3 digit addition, and 94.2% at 3-digit subtraction. Performance decreases as the number of digits increases, but GPT-3 still achieves 25-26% accuracy on four digit operations and 9-10% accuracy on five digit operations, suggesting at least some capacity to generalize to larger numbers of digits.

    To spot-check whether the model is simply memorizing specific arithmetic problems, we took the 3-digit arithmetic problems in our test set and searched for them in our training data in both the forms “<NUM1> + <NUM2> =” and “<NUM1> plus <NUM2>”. Out of 2,000 addition problems we found only 17 matches (0.8%) and out of 2,000 subtraction problems we found only 2 matches (0.1%), suggesting that only a trivial fraction of the correct answers could have been memorized. In addition, inspection of incorrect answers reveals that the model often makes mistakes such as not carrying a “1”, suggesting it is actually attempting to perform the relevant computation rather than memorizing a table.
