      Some people, like Christof Koch, think that a simulation cannot become conscious. The irony is that only simulations can be conscious. Consciousness is a simulated property of a simulated system.

      what is your criterion to tell apart a simulated system from a... also, what's the opposite of a simulated system?

      The ground truth has an actually implemented transition function. A simulacrum can only be described as if it did. I think that is what the difference comes down to. Most models are simulacra.

      Is this about levels of description? Every system ultimately runs on the ground truth transition function, so nothing is a simulation, but if we don't impose functional subsystem-boundaries we're lost -- and yours is: consciousness is computational, substrate is a distraction?

      The question of a simulation is one of observability. A simulation is observable from the outside, but cannot observe the outside. This means the effective transition function of a simulation is the one needed to explain its observable transitions, not the ground truth one.

      Because consciousness cannot be real. One cannot "have" consciousness unless one is a subject, and no physical system qualifies as subjective. However, it is not impossible for a physical system to create the narrative of a subjective being, and we are such a narrated fiction.

          Hmm, I don't think I get your . Having consciousness relies on a form self-observation, which is not natively possible for a physical system. The processes of the system itself as a first-class part of the input to them must be provided from the outside -> only in ¿simulations?.
