Your brain does not process information, retrieve knowledge or store memories. In short: your brain is not a computer

the-podcast guy recently linked this essay, its old, but i don’t think its significantly wrong (despite gpt evangelists) also read weizenbaum, libs, for the other side of the coin

    Given these facts, Jasanoff argues, you could build a chemistry-centric model of the brain with electrical signals of neurons facilitating the movement of chemical signals, instead of the other way around. The electrical signals could be viewed as part of a chemical process because of the ions they depend on. Glia cells affect the uptake of neurotransmitters which in turn affects neuron firing. From an evolutionary perspective, the chemical brain is no different than the chemical liver or kidneys.

    An epigenetic understanding of dopamine, drug addiction, and depression focuses on the chemistry in the brain, not the electrical circuitry.

    Our brains function just like the rest of our biological body, not as an abstraction of hardware and software components. To Jasanoff, there is no distinction between a mental event and a physical event in the body.

    Humans rely on intuition, worldviews, thoughts, beliefs, our conscience. Machines rely on algorithms, which are inherently dumb. Here’s David Berlinski’s definition of an algorithm:

    “An algorithm is a finite procedure, written in a fixed symbolic vocabulary, governed by precise instructions, moving in discrete steps, 1, 2, 3, . . ., whose execution requires no insight, cleverness, intuition, intelligence, or perspicuity, and that sooner or later comes to an end.”

    But not every machine relies on dumb algorithms alone. Some machines are capable of learning. So, we must dive a little deeper to understand the inner workings of AI. I like this definition from John C. Lennox PhD, DPhil, Dsc – Professor of Mathematics (Emeritus) at the University of Oxford:

    “An AI system uses mathematical algorithms that sort, filter and select from a large database.

    The system can ‘learn’ to identify and interpret digital patterns, images, sound, speech, text data, etc.

    It uses computer applications to statistically analyse the available information and estimate the probability of a particular hypothesis.

    Narrow tasks formerly (normally) done by a human can now be done by an AI system. It’s simulated intelligence is uncoupled from conscience.”

    Sort, filter and select. If you put it as simply as this, which to my opinion is the case, then you realize that AI is completely different from the human brain, let alone who we are as human beings.

      You can build a computer out of anything that can flip a logic gate, up to and including red crabs. It doesn’t matter if you’re using electricity or chemistry or crabs. That’s why it’s a metaphor. This really all reads as someone arguing with a straw man who literally believes that neurons are logic gates or something. “Actually brains have chemistry” sounds like it’s supposed to be a gotcha when people are out there working on building chemical computers, chemical data storage, chemical automata right now. There’s no dichotomy there, nor does it argue against using computer terminology to discuss brain function. It just suggests a lack of creativity, flexibility, and awareness of the current state of the art in chemistry.

      It’s also apparently arguing with people who think chat-gpt and neural nets and llms are intelligent and sentient? In which case you should loudly specify that in the first line so people know you’re arguing with ignorant fools and they can skip your article.

      Humans rely on intuition, worldviews, thoughts, beliefs, our conscience. Machines rely on algorithms, which are inherently dumb. Here’s David Berlinski’s definition of an algorithm: “An algorithm is a finite procedure, written in a fixed symbolic vocabulary, governed by precise instructions, moving in discrete steps, 1, 2, 3, . . ., whose execution requires no insight, cleverness, intuition, intelligence, or perspicuity, and that sooner or later comes to an end.”

      And what the hell is this? Jumping up and down and screaming “i have a soul! Consciousness is privileged and special! I’m not a meat automata i’m a real boy!” Is not mature or productive. This isn’t an argument, it’s a tantrum.

      The deeper we get in to this it sounds like dumb guys arguing with dumb guys about reductive models of the mind that dumb guys think other dumb guys rigidly adhere to. Ranting about ai research without specifying whether you’re talking about long standing research trends or the religious fanatics in California proseletyzing about their fictive machine gods isn’t helpful.

        “an algorithm is a finite set of instructions that can be followed mechanically, with no insight required, in order to give some specific output for a specific input.” Now if we assume that the input and output states are arbitrary and not specified, then time evolution of any system becomes computing it’s time-evolution function, with the state at every time t becoming the input for the output state at time (t+1), and hence too broad a definition to be useful. If we want to narrow the usage of the word computers to systems like our laptops, desktops, etc., then we are talking about those systems in which the input and output states are arbitrary (you can make Boolean logic work with either physical voltage high or low as Boolean logic zero, as long you find suitable physical implementations) but are clearly specified (voltage low=Boolean logic zero generally in modern day electronics), as in the intuitive definition of an algorithm….with the most important part being that those physical states (and their relationship to the computational variables) are specified by us!!! All the systems that we refer to as modern day computers and want to restrict our usage of the word computers to are in fact our created by us(or our intelligence to be more specific), in which we decide what are the input and output states. Take your calculator for example. If you wanted to calculate the sum of 3 and 5 on it, it is your interpretation of the pressing of the 3,5,+ and = buttons as inputs, and the number that pops up on the LED screen as output is what allows you interpret the time evolution of the system as a computation, and imbues the computational property to the calculator. Physically, nothing about the electron flow through the calculator circuit makes the system evolution computational.

        you literally ignore the actual part of the text that adresses your problems.

        you can use the word ‘tantrum’ while you ignore the literal words used and their meanings if you want but it only makes you seem illiterate and immature.

        ‘intuition worldviews thoughts beliefs our conscience’ are specific words with specific meanings. no computer (information processing machine) has ‘consciousness’, no computer has ‘intuition’, no computer has internal subjective experience - not even an idealized one with ‘infinite processing power’ like a turing machine. humans do. therefore humans are not computers. we cannot replicate ‘intuition’ with information processing, we cannot replicate ‘internal subjective experience’ with information processing. we cannot bridge the gap between subjective internal experience and objective external physical processes, not even hypothetically, there is not even a theoretical experiment you could design for it, there is not even theoretical language to describe it without metaphor. We could learn and simulate literally every single specific feature of the brain and it would not tell us about internal subjective experiences, because it is simply not the kind of phenomena that is understood by the field of information processing. If you have a specific take on the ‘hard problem of consciousness’ thats fine, but to say that ‘anyone who disagrees with me about this is just stupid’ is immature and ignorant, especially in light of your complete failure to understand things like Turing machines.

        I usually like your posts and comments but this thread has revelaed a complete ignorance of the philosophical and theoretical concepts under discussion here and an overzealous hysteria regarding anything that is remotely critical of a mechanistic physicalist reductionist worldview. you literally ignore or glazed over any relevant parts of the text i quoted, misunderstood the basic nature of what a turing machine is, misunderstood the nature of the discourse around the brain-as-computer discourse, all with the smuggest redditor energy humanly possible. I will not be further engaging after this post and will block you on my profile, have a nice life.
