    let alone if it’s technically “real” (as in physical in any way.)

    This right here might already be a flaw in your argument. Something doesn’t need to be physical to be real. In fact, there’s scientific evidence that physical reality itself is an illusion created through observation. That implies (although it cannot prove) that consciousness may be a higher construct that exists outside of physical reality itself.

    If you’re interested in the philosophical questions this raises, there’s a great summary article that was published in Nature: https://www.nature.com/articles/436029a

      On the contrary, it’s not a flaw in my argument, it is my argument. I’m saying we can’t be sure a machine could not be conscious because we don’t know that our brain is what makes us conscious. Nor do we know where the threshold is where consciousness arises. It’s perfectly possible all we need is to upload an exact copy of our brain into a machine, and it’d be conscious by default.

        I see that’s certainly a different way of looking at it :) Of course I can’t say with any authority that it must be wrong, but I think it’s a flaw because it seems you’re presuming that consciousness arises from physical properties. If the physical act of copying a brain’s data were to give rise to consciousness, that would imply consciousness is a product of physical reality. But my position (and that of the paper I linked) is that physical reality is a product of mental consciousness.

            Do elaborate on the batshit part :) It’s a scientific fact that physical matter does not exist in its physical form when unobserved. This may not prove the existence of consciousness, but it certainly makes it plausible. It certainly invalidates physical reality as the “source of truth”, so to say. Which makes the explanation that physical reality is a product of consciousness not just plausible, but more likely than the other way around. Again, not a proof, but far from batshit.

              No, it’s not. The quantum field and the quantum wave exist whether or not you observe it, only the particle behavior changes based on interaction. Note how I specifically used the word “interaction”, not “observation”, because that’s what a quantum physicist means when they say the wave-particle duality depends on the observer. They mean that a wave function collapses once it interacts definitely, not only when a person looks at it.

              It certainly invalidates physical reality as the “source of truth”, so to say

              How so, when the interpretation you’re citing is specifically dependant on the mechanics of quantum field fluctuation? How can physical reality not exist when it is physical reality that gives you the means to (badly) justify your hypothesis?

              I think you’re a little confused about what observed means and what it does.
              When unobserved, elementary particles behave like a wave, but they do not stop existing. A wave is still a physical thing. Additionally, observation does not require consciousness. For instance, a building, such as a house, when nobody is looking at it, does not begin to behave like a wave. It’s still a physical building. Therefore, observation is a bit of a misnomer. It really means a complex interaction we don’t understand causes particles to behave like a particle and not a wave. It just happens that human observation is one of the possible ways this interaction can take place.
              An unobserved black hole will still feed, an unobserved house is still a house.
              To be clear, I’m not insulting you or your idea like the other dude, but I wanted to clear that up.

                Thanks, that seems a fair approach, although it doesn’t have me entirely convinced yet. Can you explain what the physical form of a wave function is? Because it’s not like a wave, such as waves in the sea. It’s really a wave function, an abstract representation of probabilities which in my understanding does not have any physical representation.

                You say the building does not start acting like a wave, and you’re right, that would be silly. But it does enter into a superposition where the building can be either collapsed or not. Like Schreudinger’s cat, which can be dead or alive, and will be in a superposition of both until observation happens again. And yes, the probabilities of this superposition are indeed expressed through the wave function, even though there is no physical wave.

                It’s true observation does not require consciousness. But until we know what does constitute observation, I believe consciousness provides a plausible explanation.

                  A building does not actually enter a superposition when unobserved, nor does Schrodinger’s cat. The point of that metaphor was to demonstrate, through humor, the difference between quantum objects and non-quantum objects, by pointing out how ridiculous it would be to think a cat could enter a superposition like a particle. In fact, one of the great mysteries of physics right now is why only quantum objects have that property, and in order to figure that out we have to figure out what interaction “observation” actually is.
                  Additionally, we can observe the effects of waves quite clearly. We can observe how they interact with things, how they interfere with each other, etc. It is only attempting to view the particle itself that causes it to collapse and become a particle and not a wave. We can view, for instance, the interference pattern of photons of light, behaving like a wave. This proves that the wave is in fact real, because we can see the effects of it. It’s only if we try to observe the paths of the individual photons that the pattern changes. We didn’t make the photons real, we could already see they were real by their effects on reality. We just collapsed the function, forcing them to take a single path.

                    This does not stroke with my understanding of quantum physics. As far as we know there is no clear distinction between “quantum objects” vs “non-quantum objects”. The double slit experiment has been reproduced with molecules as large as 114 atoms, and there seems no reason to believe that would be the upper limit: https://www.livescience.com/19268-quantum-double-slit-experiment-largest-molecules.html

                    This proves that the wave is in fact real, because we can see the effects of it.

                    The only part that’s proven is the interference pattern. So yes, we know it acts like a wave in that particular sense. But that’s not the same thing as saying it is a wave in the physical sense. A wave in the classic physical sense doesn’t collapse upon observation. I know it’s real in an abstract sense. I’m just questioning the physical nature of that reality.
