The article come from a long line of reasons that no longer has anything useful to say nowaday. We don't ask priets to bless our computers to avoid security issues, and we shouldn't bother listening to these "philosphers".

What would be really interesting instead would be to admit that there's lots of knowledge and questions that are not encompassed by any particular discipline but instead lay at the interfaces between domains, that mondels like those oh philosophy no longer address well (and religion no longer provides useful psychological tools for), and re-image a new kind of philosophy build from the ground up on the idea of computation, and in this new discipline re-define +/- break apart fuzzy concepts like consciousness so that we finally have something to talk and think about!

What word would you use to describe the subjective experiences of people? What word do you describe something like the taste of an apple, or the appearance of the color red? That is what Qualia refer to. I would say that it is intuitively sensible that these subjective experience exist, at least for any reasonable definition of existence.

When I taste an apple that corresponds to some physical pattern in my brain: electrical impulses; neurotransmitters; neural connections being created or destroyed or changing in strength, etc. I see no reason that needs a special word to describe it, nor why that same pattern couldn't be represented abstractly in a formal language or translated to some other computational architecture.

What is corresponding to the physical pattern in your brain? What word would you use to describe that thing that is corresponding to the physical event?

It becomes difficult to discuss qualia because we assume their existence so often in everyday life. We talk about our emotions, or the taste of things, or the feeling of pain. All of these things are part of the same group, which is why we find a word to describe them useful.

As a potential other argument, lets say qualia do not exist, and only physical states exist. If I were then to inflict pain, would that be wrong? I would simply be causing certain chemical and electrical pathways in a humans body, which doesn't seem to have any moral quandries.

The wrongness of inflicting pain only occurs when we assume that there is some qualitative aspect to it in that I am causing another person to experience pain. This isn't an airtight proof of qualia's existence, but I think it does show that we certainly act like they exist in our day to day.

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 suspect we agree more than we disagree. But I think that your definition of a "computational process" is too broad. A bacterium does things that we can say are "performing a computation." But that is different from saying that life is, at root, a computational phenomenon. For instance, sorting a list is a computational process. It doesn't matter what kind of computer I run a sorting algorithm on, if I follow the al…

> I suspect we agree more than we disagree.

I suspect the same, but I think there is tremendous value in taking a cosmic step back and seeing everything through the lens of information. It's the most reductionist neutral approach to the universe I can conceive us at this point in my life.

> By contrast, if I construct a collection of chemicals that matches the positions of those of a real bacterium, I have created a new bacterium. However, if I simulate the activity of those chemicals on a computer, I have not created a bacterium. I have just created a simulation of a bacterium. I haven't created a living thing.

I agree, but I think the context matters: you may not have created a bacteria, but that's because you've emulated a bacteria in a totally different environment. The bacteria makes no sense as a computational engine if you separate it from its environment, which is chemical in nature: this chemical environment must also be emulated inside the computer. So if we're going to take the idea of life as a computation seriously and to the extreme, we need to conceive of it as it exists within its environment and in the context within which it evolved. Otherwise what you've created, grossly speaking, is a function that is never called, which of course is much less interesting.

Similarly for the brain, it must also be embodied, and you must also simulate its afferent inputs, and you must also give it an environment with which to interact and within which to exhibit features of agency. If you emulate the embodied brain with its environment, I contend that it doesn't matter what the substrate is: the brain you will have created will "feel" just as real to itself. It will perceive itself as being "conscious" just as well as you and I.

Note that for this to make any sense in a relatable way to a human, it's not enough to just throw large numbers of neurons together, as I understand is common practice in AI work even today: a long-learned lesson in both neuro and biochem is that function follows structure, so you must emulate the gross organizational structure of the human brain in order to observe the same sorts of features that make up human-flavoured consciousness.

If you compute consciousness, there will be zero distinction between how the computation feels real to itself, and how you and I feel to ourselves. That "magic" feeling we get where we have the impression that we're "someone", with a personal identity, that we're real, that we're alive, that we're aware, that we can make our own decisions... All of that stuff, your emulated consciousness will also experience. It won't be just bits turning on and off from its point of view: it will feel alive.

Consciousness might just be the brain's recurrent and unsuccessful attempt at predicting itself.

Similarly, "free will" may simply be an illusion caused by the failure of that perfect prediction of what to do/what will happen, thus leaving us with a pleasant stochasticity that we end up favoring as freedom :)

I find this argument completely unconvincing. The mapping in a case like the iron bar is entirely ephemeral, pertaining only for an instant. For this argument to be valid you’d have to be able to persistently map the iron bar, or waterfall, to all ongoing transformations of states in the running program, using one single consistent mapping. Otherwise all you have is a snapshot of state, not an ongoing process. To ach…

Computation does not have anything essential to it that makes it different from other "atoms jumping around" other than it produces outputs that we find interesting. There's no reason to expect an adder circuit to be aware that it's adding numbers. There's no reason to expect an implementation of AlphaGo to know that it's playing Go. This should be extendable without limitation. There's no reason to expect that a cer…

There is no reason to expect a neuron to be aware that it's propagating part of the evolution of an epiphany.

The argument seems to be that beyond a certain level of complexity you'll somehow automatically get consciousness.

Clearly it's unlikely this is a hard cut off. Adding one more byte of RAM, expanding the CPU from 64 to 128-bit words, or adding another dimension to a neural network isn't going to do it.

But if consciousness emergent, how do you measure the amount of consciousness?

Because the experience is subjective, you can't just assume that behaviours that appear conscious are proof that consciousness exists.

You could - presumably - build a Turing bot, but it would still be an automaton.

So you're left with people making very definitive statements about something which everyone experiences, but no one can measure or even define.

I disagree about where the burden of proof lies. If we start off firstly with the assumption that humans have consciousness, and secondly the decently supported claim that animals exhibit what to us appears to be consciousness on a spectrum, and thirdly that we don't exactly know how or why consciousness exists, then the conclusion that seems obvious to me is that we cannot rule out that it could emerge in a network…

> the conclusion that seems obvious to me is that we cannot rule out that it could emerge in a network Not being able to rule out consciousness through computation is a far more cautious claim than 'consciousness is computation'.

Sure. But I was responding to the statement "The burden of proof is on the claim that you can get there through computation, not otherwise."

"Consciousness is an illusion" I take the word "illusion" to mean, some type of experience which misleads one about reality. And "consciousness" to mean, the experience of having experiences. So I parse this claim as something like, "People both do not have conscious experiences, and also do continuously have a particular type of conscious experience: a misleading experience which leads them to believe they have cons…

The illusion is of conscious volition; that consciousness is an atomic unit in charge of your actions. The brain is in control. Whether the conscious ‘mind’ has any control at all is debatable.

> The brain is in control.

The brain is always in control. When you are awake, when you are sleeping, when you are under general anesthesia, when you are sleepwalking, when you are blackout drunk, and so on.

It's a trivial statement, which doesn't say anything about why some of these states aren't like the others. And there's a strange coincidence: when the brain creates that "illusion of control", your body behaves differently than when it doesn't.

That is strictly true, but if you define computation as any physical process which involves information, as I do, then defending any other position than "consciousness emerges from computation" is extremely difficult.
