>Will it also be conscious and experience sadness? Imagine you are programming an AI simulation. You could train a detector to associate a certain wavelength with a certain color. When shown a red light, the AI could say "that is red", because it correctly identified the wavelength. But it would never know what it feels like to see red, right? This is similar to how a blind person cannot know what it feels like to se…

I appreciate your response, but it's impossible for me to imagine programming an AI simulation capable of feeling the perception of red. The idea that I can't imagine doing these things is because of a shortcoming in my knowledge. Maybe that knowledge is out there, or maybe it isn't. So the exercise gets us no closer to answering the question at hand. But what I can do is imagine creating a physics simulation. There'…

>The idea that I can't imagine doing these things is because of a shortcoming in my knowledge.

I don't think there is a shortcoming in your knowledge. Your metaphysics intuition is correctly tuned: simulations cannot feel.

>We create a physics simulation of a human brain. Can the brain write a novel? Answer questions about what it's like to perceive the color red? This is just a yes or no question.

GPT-3 can do both of these things. Is it conscious? If you need a direct answer, it is yes. But when we reword your second question as "can a simulated brain experience the color red?" the answer becomes more clear; the simulation can identify a wavelength and know it is called "red". But the experiential part is akin to explaining color to a blind person.

A simulated brain could identify molecular patterns of cocoa and sugar, but can it know what it is like to taste chocolate? Think about what it means to taste chocolate. Is it purely quantitative, like the balance of ingredients, or is there something else going on that is qualitative? Something abstract, something with meaning, something more close to the metal? We can probably agree that it feels like there is. What we are describing is subjectivity — your private conscious inner life. I suggest it is this that is fundamental and cannot be simulated. This is the layer where experience "happens". From this layer emerges meta-consciousness.

No. Some things are Turing machines and some are not. Human interaction and interpretation are not involved. This applies to any model of computation. Cellular autonoma for instance. A mind is not required to interact with the system for computation to take place. Take a living cell.

Again, no, not anything can a computer. If you like Turing machines, there are specific requirements for what makes a Turing machine. None of these things are ingredients of a Turing machine:

    * Observation
    * Measurement
    * Interpretation
    * Intent
    * A mind
> My contention is that whether that arrangement of objects is in fact a computer is subjective

You are wrong. It is discretely defined. Read about the requirements for a Turing machine.

    * When the requirements are *not* met,
      subjectivity can not turn something
      into a computer.
    * When the requirements *are* met,
      subjectivity can not change the fact
      that it is computer.
It's obvious that subjectivity has no effect -- either in the matter of classifying computers, or allowing computation to take place.

> it depends on whether anyone conceives of it as a computer, or uses it to obtain computational results.

Again, refuted, in so many different ways. Here's an obvious one which I will restate:

    * Cells inarguably perform computation.
      They pre-date minds by billions of years.
Put a different way, if a Turing Machine computes in the woods and there's no one around to see it, computation will still have taken place. The burden of proof would be on you to say otherwise. I only see two very messy and wrong arguments:

A) Iron bars don't compute by themselves --> A mind is needed to "map" iron bars to "states of an arbitrary Turing machine"

It doesn't follow. Iron bars don't compute on their own because they are just the memory component. What is missing is MACHINERY WITH SPECIFIC PROPERTIES to complete a Turing machine. If the machinery is present, computation is possible. No mind necessary.

B) Socks are a computer if I decide they are --> arbitrary objects can in principle compose a computer --> deciding is necessary to make computers.

It doesn't follow. While computers could be made of just about anything, fully arbitrary objects cannot be computers. Only specific systems yield computation. Decision has nothing to do with it. Not even observation is required.

> there's a steady flow of people discovering that some X is a Turing-complete language, when X wasn't actually even meant to be a language at all.

You're arguing my point. "discovering" Turing machines ... meaning some things are already Turing machines before a mind became involved.

> So it seems that some configuration of stuff is a computer IFF (a) it is capable of doing computation, and (b) someone is willing to consider it as a computer.

You say "So it seems" and "IFF" but it does not follow at all. (b) is not supported. Computation can happen without "someone".

At best, you're arguing that trees falling in the forrest make no sound.

Anyway, why do I think I have time for this ...

OK, so a simulated human brain acts the same as a real human brain, is capable of the same things, tells you that yes, it can experience the color red, etc, but does not have any internal conscious experience.

Why then would evolution produce beings with internal conscious experience?

This would also mean that our internal conscious experience has no effect on what decisions we make, on whether we cry, smile, what memories we form, etc.

(Author here.) This is a false dichotomy. Saying that consciousness is not fundamentally a computational process does not mean that it then has to be magic. We could say the same thing about life. Life is not a computational phenomenon. But it is also not magic. It is, fundamentally, a particular kind of chemical process. Perhaps the same is true of consciousness, or maybe it is some other kind of physical process. I…

I would absolutely argue that life is a particular category of computation as well, and that is actually closer to my area of expertise (biochemistry) than consciousness / neuro. For clarity: when I say "computation", I refer to any physical process ("physics") which involves information.

I think the parent author may be talking about life in a phenomenological model as in how we experience something vs knowing about it epistemologically. Often that gets mixed up. Knowing doesn't equal experiencing. This is something often the technocrats misses.

>Why then would evolution produce beings with internal conscious experience?

Well, I'm arguing it's the other way around. But to address what I think is the spirit of your question: if reality is only mind, if consciousness is truly fundamental, then why can't you read my thoughts? Why do we feel like individuals? Why do we have obviously separate private conscious inner lives?

When you are asleep and dreaming, your "alter" generally does not know they are dreaming. Your dream self has dissociated from your waking self, but it is only after you wake up that you realize you were dreaming (if you even remember). Another example of this phenomenon is Dissociative Identity Disorder, where one mind splits into many alters, each unaware the others exist. I'm glossing over a significant amount in order to get to my point, but here are a couple links that go into great detail:

- https://www.google.com/books/edition/_/JCdbmFCHYB0C?hl=en&gb... (chapter 5)

- https://www.mdpi.com/2409-9287/2/2/10/htm#sec4-philosophies-... (search for "Yet, we know empirically that living people have separate, private experiences (Fact 6)")

My point is, our private conscious inner lives are dissociations, alters, from a "mind-at-large" fundamental consciousness. And the boundaries of these dissociations, the "containers" of individual private conscious inner life, (again glossing over so much, like panpsychism's combination problem) are metabolizing organisms. Metabolizing organisms are what alters _look like_ from the outside. Kastrup:

"Since we only have intrinsic access to ourselves, we are the only structures known to have dissociated streams of inner experiences. We also have good empirical reasons to conclude that normal metabolism is essential for the maintenance of this dissociation, for when it slows down or stops the dissociation seems to reduce or end. These observations alone suggest strongly that metabolizing life is the structure corresponding to alters of [fundamental consciousness]

But there is more: insofar as it resembles our own, the extrinsic behavior of all metabolizing organisms is also suggestive of their having dissociated streams of inner experiences analogous to ours in some sense" (from the mdpi link)

>This would also mean that our internal conscious experience has no effect on what decisions we make, on whether we cry, smile, what memories we form, etc.

Don't your thoughts and feelings influence your behavior?

The key error in the argument is here: "[T]he only reason we call a box with a CPU in it a “computer” is because we happen to have a simple mapping between the voltage levels across different parts of the CPU to a set of bits we have defined, and when these voltages interact they do so according to the rules of a set of logical operations which we have also defined. But there is no meaning to the physical system apar…

There are documented cases of people in comas/full paralysis who later wake up and remember being conscious throughout the coma. If they never woke up to tell anyone about it (or died before they had the chance to wake up) would they not have been conscious? We can of course observe that there is brain activity to some degree but I'm not sure that we would consider that output in a meaningful way anymore than somethi…

Is a computer not computing if it's not outputting? If I'm thinking for an extended period of time without telling other "people" my thoughts am I actually thinking? If a tree falls in a forest, and there’s no one around to hear it, does it make a sound?

Looking at things like anaesthetics, psychedilic drugs, delerium, sleep, etc, there seems to be plenty of evidence that the phenomena of consciousness is related to the mechanics of the brain. There's also the interesting medical condition of "blindsight", caused by a specific type of brain damage, where the patient reports no conscious awareness of being able to see (they think they are blind), yet are able to compe…

> The point is that our ability to recognise whether or not an entity has some level of awareness or subjective experience is entirely dependent on our ability to interrogate that entity about it. We have no other way of measuring this; we don't even know what we'd need to measure.

You can't have any subjective experience of something unless that something exists in the first place, so interrogating about "how does it feel" seems rather secondary, as well as not being proof of anything. If LaMBDA says it's conscious, is that all the proof you want?

Let's also note that IF we knew, for sure, that the bag of subjective phenomena we're calling "consciousness" is nothing more than an emergent experience based on a sensory/cognitive apparatus having access to it's own internal states, then it would be pretty clear what type of animals/systems are likely have this (and which ones certainly not), since without any sensory/cognitive apparatus it could not exist. It then would seem very likely that the guy in the next cubicle is conscious since he has the same brain architecture as us, and most animals too, unless you get down to the level of insects and below in terms of complexity of nervous systems.

So, your assertion that the only way to assess whether something is conscious is to interrogate it, rests entirely on the above being incorrect and consciousness being some mystical/dualistic phenomena who's existence we can't deduce from a functional analysis of the "brain" of the thing in question.

You may still be correct in a round about sort of way since I doubt most people will accept that AIs could be conscious until such things exist, and are common enough that people can spend considerable time interacting with them, and through the unreliable measure of interrogation eventually convince themselves that "yeah, well, I suppose it might be .. is does SEEM to be ..".

It seems long due really ... first we had people denying Copernicus, then Darwin, and perhaps this will be the final step in people eventually accepting that there's really nothing much special about humans at all. Who knows, maybe we're too dumb as a species to realize it, and it'll be some more advanced future species writing textbooks about the odd beliefs of homo sapiens at this "emerging intelligence" phase of evolution.

Name one.

I showed you that subjectivity doesn’t effect whether computation occurs. Several ways.

If you disagree you should really be editing Wikipedia: https://en.m.wikipedia.org/wiki/Model_of_computation Why don’t you go add your theory there?

It’s silly because it’s obvious. If you understand cells, you understand that computation in the absence of subjectivity has been happening on Earth for billions of years.

> I showed you that subjectivity doesn’t effect whether computation occurs.

You didn't "show" it; you simply asserted it. You also made a number of appeals to (uncited) authority concerning the nature of computers.

You made an argument from cells; I presume that was to do with the way that DNA and so on works. Although not all cells have DNA...

Anyway. I concede that was an argument, and not a bald assertion. But it's a circular argument; if your definition of "computer" includes the operation of DNA, then the conclusion that a computer can exist without interpretation or intent is unavoidable. You're definition begs the question.
