    Damn, I was going to ship of Theseus you about the cells in your body replacing themselves constantly, but apparently our brain neurons last a lifetime.

    Now I don’t think I would ever use a teleporter, either. Shit.

        Its kinda crazy actually if you think about it, our ability to anticipate actions is our ability to land in outcomes expected to be made by the reality generating around us if you imagine the reality outside our bodily sensory input as a big monte carlo field of potentials in the form of intertwined variables…like a big llm.

          Aren’t LLMs basically pattern matching systems.

          Humans are also pattern matching, and then predicting machines, but with way more inputs and senses than the LLMs.

            They don’t match anything but do trigger the “nearest” response to a stimulus, so kinda like pattern matching but that implies doing it on purpose. But yeah the rest I agree with.

      That is why nervous system damage usually means life long problems. Brains and all their wiring are so arcane and complicated, even our bodies don’t know how to grow more than one of them, and we often don’t get it right the first time either unfortunately.

      muscle cells too. the muscle cells you have now are the same cells you had as a kid (not entirely sure how far back it goes). they dont even divide when you gain muscle, the cells just get bigger and absorb nuclei from neighboring cells to support the extra mass. the cool thing is the nuclei stick around even if you let the muscles atrophy, so theyre forever changed by having once been big. thats probably part of why its easier to get back to muscle size youve been at before.

        So far that we know of, neural cell DNA, tooth enamel, and eye lens crystallines, never have their atoms replaced.

        Which is to say that we are a ship of theseus, and a transporter does not kill us. The only reason these atoms are not normally replaced is because there is no natural mechanism to replace them.

          Not sure I would tie my identity to my neuron DNA, tooth enamel, and eye lens crystallines. Definitely agree with you that we are living ships of Theseus. I’m pretty sure there’s no natural mechanism to replace those parts because it’s really hard, and we work “well enough” without being able to.

      Yeah but we don’t know if consciousness lives in the meat or in the chemistry.
