There 100% are…

If you choose to believe so, like I said I don’t really care. Is a quantum computer conscious? I think it’s a bit irrelevant whether or not they exist. I will concede they do for the sake of discussion.

Penrose thinks they’re responsible for consciousness.

Yeah, and as I said, Penrose was wrong, not because the measurement problem isn’t the cause for consciousness, but that there is no measurement problem nor a “hard problem.” Penrose plays on the same logical fallacies I pointed out to come to believe there are two problems where none actually exist and then, because both problems originate from the same logical fallacies. He then notices they are similar and thinks “solving” one is necessary for “solving” the other, when neither problems actually existed in the first place.

Because we also don’t know what makes anesthesia stop consciousness. And anesthesia stops consciousness and stops the quantum process.

You’d need to define what you mean more specifically about “consciousness” and “quantum process.” We don’t remember things that occur when we’re under anesthesia, so are we saying memory is consciousness?

Now, the math isn’t clean. I forget which way it leans, but I think it’s that consciousness kicks out a little before the quantum action is fully inhibited? It’s been a minute, and this shit isn’t simple.

Sure, it’s not simple, because the notion of “consciousness” as used in philosophy is a very vague and slippery word with hundreds of different meanings depending on the context, and this makes it seem “mysterious” as its meaning is slippery and can change from context to context, making it difficult to pin down what is even being talked about.

Yet, if you pin it down, if you are actually specific about what you mean, then you don’t run into any confusion. The “hard problem of consciousness” is not even a “problem” as a “problem” implies you want to solve it, and most philosophers who advocate for it like David Chalmers, well, advocate for it. They spend their whole career arguing in favor of its existence and then using it as a basis for their own dualistic philosophy. It is thus a hard axiom of consciousness and not a hard problem. I simply disagree with the axioms.

Penrose is an odd case because he accepts the axioms and then carries that same thinking into QM where the same contradiction re-emerges but actually thinks it is somehow solvable. What is a “measurement” if not an “observation,” and what is an “observation” if not an “experience”? The same “measurement problem” is just a reflection of the very same “hard problem” about the supposed “phenomenality” of experience and the explanatory gap between what we actually experience and what supposedly exists beyond it.

It’s the quantum wave function collapse that’s important.

Why should I believe there is a physical collapse? This requires you to, again, posit that there physically exists something that lies beyond all possibilities of us ever observing it (paralleling Kant’s “noumenon”) which suddenly transforms itself into something we can actually observe the moment we try to look at it (paralleling Kant’s “phenomenon”). This clearly introduces an explanatory gap as to how this process occurs, which is the basis of the measurement problem in the first place.

There is no reason to posit a physical “collapse” or even that there exists at all a realm of waves floating about in Hilbert space. These are unnecessary metaphysical assumptions that are purely philosophical and contribute nothing but confusion to an understanding of the mathematics of the theory. Again, just like Chalmers’ so-called “hard problem,” Penrose is inventing a problem to solve which we have no reason to believe is even a problem in the first place: nothing about quantum theory demands that you believe particles really turn into invisible waves in Hilbert space when you aren’t looking at them and suddenly turn back into visible particles in spacetime when you do look at them.

That’s entirely metaphysical and arbitrary to believe in.

There’s no spinning out where multiple things happen, there is only one thing. After wave collapse, is when you look in the box and see if the cats dead. In a sense it’s the literal “observer effect” happening our head. And that is probably what consciousness is.

There is only an “observer effect” if you believe the cat literally did turn into a wave and you perturbed that wave by looking at it and caused it to “collapse” like a house of cards. What did the cat see in its perspective? How did it feel for the cat to turn into a wave? The whole point of Schrodinger’s cat thought experiment was that Schrodinger was trying to argue against believing particles really turn into waves because then you’d have to believe unreasonable things like cats turning into waves.

All of this is entirely metaphysical, there is no observations that can confirm this interpretation. You can only justify the claim that cats literally turn into waves when you don’t look at them and there is a physical collapse of that wave when you do look at them on purely philosophical grounds. It is not demanded by the theory at all. You choose to believe it purely on philosophical grounds which then leads you to think there is some “problem” with the theory that needs to be “solved,” but it is purely metaphysical.

There is no actual contradiction between theory and evidence/observation, only contradiction between people’s metaphysical assumptions that they refuse to question for some reason and what they a priori think the theory should be, rather than just rethinking their assumptions.

That’s how science works. Most won’t know who Penrose is till he’s dead.

I’d hardly consider what Penrose is doing to be “science” at all. All these physical “theories of consciousness” that purport not to just be explaining intelligence or self-awareness or things like that, but more specifically claim to be solving Chalmers’ hard axiom of consciousness (that humans possess some immaterial invisible substance that is somehow attached to the brain but is not the brain itself), are all pseudoscience, because they are beginning with an unreasonable axiom which we have no scientific reason at all to take seriously and then trying to use science to “solve” it.

It is no different then claiming to use science to try and answer the question as to why humans have souls. Any “scientific” approach you use to try and answer that question is inherently pseudoscience because the axiomatic premise itself is flawed: it would be trying to solve a problem it never established is even a problem to be solved in the first place.
