  • It is my opinion that repeating decimals cannot

    Your opinion is incorrect as a question of definition.

    I have never disagreed with the math

    You had in the previous paragraph.

    Is it possible to have a coversation about math without either fully agreeing or calling the other stupid?

    Yes, however the problem is that you are speaking on matters that you are clearly ignorant. This isn’t a question of different axioms where we can show clearly how two models are incompatible but resolve that both are correct in their own contexts; this is a case where you are entirely, irredeemably wrong, and are simply refusing to correct yourself. I am an algebraist understanding how two systems differ and compare is my specialty. We know that infinite decimals are capable of representing real numbers because we do so all the time. There. You’re wrong and I’ve shown it via proof by demonstration. QED.

    They are just symbols we use to represent abstract concepts; the same way I can inscribe a “1” to represent 3-2={ {} } I can inscribe “.9~” to do the same. The fact that our convention is occasionally confusing is irrelevant to the question; we could have a system whereby each number gets its own unique glyph when it’s used and it’d still be a valid way to communicate the ideas. The level of weirdness you can do and still have a valid notational convention goes so far beyond the meager oddities you’ve been hung up on here. Don’t believe me? Look up lambda calculus.







  • If I remember, I’ll give a formal proof when I have time so long as no one else has done so before me. Simply put, we’re not dealing with floats and there’s algorithms to add infinite decimals together from the ones place down using back-propagation. Disproving my statement is as simple as providing a pair of real numbers where doing this is impossible.




  • I can’t help but notice you didn’t answer the question.

    each digit-wise operation must be performed in order

    I’m sure I don’t know what you mean by digit-wise operation, because my conceptuazation of it renders this statement obviously false. For example, we could apply digit-wise modular addition base 10 to any pair of real numbers and the order we choose to perform this operation in won’t matter. I’m pretty sure you’re also not including standard multiplication and addition in your definition of “digit-wise” because we can construct algorithms that address many different orders of digits, meaning this statement would also then be false. In fact, as I lay here having just woken up, I’m having a difficult time figuring out an operation where the order that you address the digits in actually matters.

    Later, you bring up “incrementing” which has no natural definition in a densely populated set. It seems to me that you came up with a function that relies on the notation we’re using (the decimal-increment function, let’s call it) rather than the emergent properties of the objects we’re working with, noticed that the function doesn’t cover the desired domain, and have decided that means the notation is somehow improper. Or maybe you’re saying that the reason it’s improper is because the advanced techniques for interacting with the system are dissimilar from the understanding imparted by the simple techniques.




  • People generally find it odd and unintuitive that it’s possible to use decimal notation to represent 1 as .9~ and so this particular thing will never go away. When I was in HS I wowed some of my teachers by doing proofs on the subject, and every so often I see it online. This will continue to be an interesting fact for as long as decimal is used as a canonical notation.


  • don’t sipport infinite decimals properly

    Please explain this in a way that makes sense to me (I’m an algebraist). I don’t know what it would mean for infinite decimals to be supported “properly” or “improperly”. Furthermore, I’m not aware of any arguments worth taking seriously that don’t use logic, so I’m wondering why that’s a criticism of the notation.




  • Not “by my definitions” by the simple fact that we can’t test for it. Technically, no one knows if any other individual has internal experiences or not. I know for a fact that my sensorium provides me data, and if I assume that data is at all accurate, I can be reasonably confident that other entities that look and behave similarly to me exist. However, I can’t verify that any of them have internal experiences the way I do. Sure, it’s reasonable to expect that, so we can just add that to the pile of assumptions we’ve been working with so far without much issue. What about other animals, like dogs? They have the same computational substrate, and the same mechanism for making those computations. I think it’s reasonable to say animals probably have internal experiences, but I’ve met multiple people who insist they somehow know they don’t, and so animal abuse is a myth. Now if we assume animals have internal experiences, what about nematodes? Nematode brains are simple enough that you can run them on a computer. If animals have internal experiences, does that include nematodes, and if so does that mean the simulated Nematode brain has internal experiences? If a computer’s subroutine can have internal experiences, what about the computer?

    Do you now understand why and what I’m saying? Where’s the line drawn? As far as I can tell, the only honest answer is to admit ignorance.



  • You’re making the implicit assumption that an entity that lacks memory necessarily does not have any internal experience, which is not something that we can know or test for. Furthermore, there’s no law of the universe that states that something created by humans cannot have an internal experience; we have no way of knowing whether something we create has an internal experience or not.

    You can think of LLMs like a hyper advanced auto correct.

    Yes; this is functionally what LLMs are, but the scope of the discussion extends beyond LLMs, and doesn’t address my core complaint about how these arguments are being conducted. Generally though maybe not universally, if a core premise of your argument is “x works differently than humans” your argument won’t be valid. I’m not currently making a claim of substance, I’m critiquing a tactic being used and pointing out that it among other things relies on a bad foundation.

    If you want to know another way to make the argument, consider focusing on the practical implications of how current and future technologies given current and hypothetical ways of structuring society. For example: the fact that generative AI (being a novel form of automation) making images will lead to the displacement of Artists, the fact that art is being used without consent to train these models which are then being used for profit, etc.
