Recovering academic now in public safety. You’ll find me kibitzing on brains (my academic expertise) to critical infrastructure and resilience (current worklife). Also hockey, games, music just because.

  • Measure differences in what? We can’t ask *c. elegans * about it’s state of mind let alone consciousness. There are several issues here; a philosophical issue here about what you are modeling (e.g. mind, consciousness or something else), a biological issue with what physical parameters and states you need to capture to produce that model, and how you would propose to test the fidelity of that model against the original organism. The scope of these issues is well outside a reply chain in Lemmy.


  • It’s an analogy. There is actually an academic joke about the point you are making.

    A mathematician and an engineer are sitting at a table drinking when a very beautiful woman walks in and sits down at the bar.

    The mathematician sighs. “I’d like to talk to her, but first I have to cover half the distance between where we are and where she is, then half of the distance that remains, then half of that distance, and so on. The series is infinite. There’ll always be some finite distance between us.”

    The engineer gets up and starts walking. “Ah, well, I figure I can get close enough for all practical purposes.”

    The point of the analogy is not that one can’t get close enough so that the ear can’t detect a difference, it’s that in theory analog carries infinite information. It’s true that vinyl recordings are not perfect analog systems because of physical limitations in the cutting process. It’s also true for magnetic tape etc. But don’t mistake the metaphor for the idea.

    Ionic movement across membranes, especially at the scale we are talking about, and the density of channels in the system is much closer to an ideal system. How much of that fidelity can you lose before it’s not your consciousness?


  • Thanks fellow traveller for punching holes in computational stupidity. Everything you said is true but I also want to point out that the brain is an analog system so the information in a neuron is infinite relative to a digital system (cf: digitizing analog recordings). As I tell my students if you are looking for a binary event to start modeling, look to individual ions moving across the membrane.


  • Sure! That’s the great thing about being a private citizen. You can live your life, go on shows, go on private vacations etc. Because it’s your life and you can choose how to live it.

    If you are taking on a role of state leadership you don’t get to do those things.

    You have a privileged role with access to roles, and wealth, and information, but the trade off is that your life is not your own. Your health and relationships and connections are a matter of national interest. So you don’t get to slip off for a weekend without telling people where you’re going. And you don’t get to hide medical diagnoses and medical treatment.

    William Roper: “So, now you give the Devil the benefit of law!”
    
    Sir Thomas More: “Yes! What would you do? Cut a great road through the law to get after the Devil?”
    
    William Roper: “Yes, I'd cut down every law in England to do that!”
    
    Sir Thomas More: “Oh? And when the last law was down, and the Devil turned 'round on you, where would you hide, Roper, the laws all being flat? This country is planted thick with laws, from coast to coast, Man's laws, not God's! And if you cut them down, and you're just the man to do it, do you really think you could stand upright in the winds that would blow then? Yes, I'd give the Devil benefit of law, for my own safety's sake!
