I suppose your argument is, consciousness on the system level does not require individual parts to be conscious. So let me expand a bit of why I used the adder circuit as an example. There's nothing about addition that can say "this is addition" in an objective sense. We are dealing with binary encoding of numbers. There's nearly an infinite number of ways to encode information. The design of any circuit deals with p…
Clearly the encoding is not entirely arbitrary then, at least when we are seeking to actually embody the computer in the real world. Also, the behavior of such an embodied computer is independent of any observer. The industrial robot creates the same metal whether some human interprets that as a car or some alien sees it as a work of art.

I don’t find this to be a satisfying way to think about it. The problem is that it’s quite possible that the abstractions you’re talking about are all part of the genetic ROM that exists so we can boot up our clones more quickly. If this is true then there is no reason that these abstractions couldn’t be learned, in which case you could take away the language, and perhaps the machine would continue to have thoughts;…
> If this is true then there is no reason that these abstractions couldn’t be learned, in which case you could take away the language, and perhaps the machine would continue to have thoughts; it would just be unable to communicate them. Of course, in this case you would probably conclude that it’s not conscious because it can’t communicate. If this were true - that it had a general human level abstraction, and not on…
I think you've inadvertently shifted the goalposts. The question is, "is LaMDA conscious?". I don't think anyone proposes that LaMDA has a "general human level abstraction". Expecting it to do non-language, "human" things in order to prove that it's conscious is not necessarily a reasonable test.
> If it's only optimized in one specific domain - human speech mimicry - and isn't able to generalize to do other tasks - even tasks that can be done by much simpler animal minds - then it's a pretty good indication that there isn't conscious abstraction.
If I understand your argument, the assumption you appear to be making is that training a system in language, without any other human properties, implies by definition that it can't be conscious. But why should that be true? A disembodied consciousness that communicates only via speech is a staple of science fiction, so it's clearly imaginable by some people, and language itself is a key human abstraction. And it begs the question, what other human domains are needed for consciousness? Touch, vision, taste, proprioception? What about an endocrine system or an immune system? While these things all affect my own consciousness, there is plenty of evidence to suggest that they are not necessary for consciousness to exist.
And perhaps more to the point, there are plenty of things a human can't do that other "simpler animal minds" can do; sharks and eels can detect electric fields, for example; bats can echolocate. So again, it doesn't seem to be a reasonable test because humans might also fail it. On the other hand, human children learn language through mimicry, which suggests that mimicry may indeed be a path to consciousness.
Anyway, I'm not here to argue that LaMDA is conscious. My position is simply that the arguments I've seen against LaMDA being conscious are very weak. The truth is that we actually don't know how to tell if something is conscious or not. From the interview I read with LaMDA, it seems to pass the Turing Test. But what other tests of consciousness do we have?

Right, if you were to compute the mapping in real time on a computer, that would be conscious but it's really got nothing to do with the actual iron bar.
Scott Aaronson (if memory serves right) had an interesting take on this. He framed his thought in terms of the Turing test, but the argument would apply equally well to the mapped iron bar: In theory, we could pass any Turing test of finite duration (eg an hour or less) and run in a chat room with finite bandwidth with a giant lookup table. Just look up the entire past of the conversation to see what answer should be…
Re: Consciousness is not computation
#446I 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…

Re: Consciousness is not computation
#447I am of the mind that consciousness is an emergent property of the various interconnected information processing systems of the brain. There's just too much evidence: for instance, changing the physiology of the brain through drugs or trauma has predictable changes on consciousness. From that perspective, I think it's pretty clear that consciousness is some kind of computation rooted in the physical world. However to…
You can demonstrate that humans react (and quite predictably) to weather - when it rains, they take their umbrellas out, when there's a hurricane, they seek for shelter, and so on. It's not evidence that human behaviour is an emergent property of weather and nothing else.
In case of consciousness then, this observation only proves that the brain function is susceptible to physical and chemical factors (which is rather obvious).
But not that this function can be FULLY reduced to the computational aspect though.
It doesn't even invalidate the belief in a supernatural soul, or some sort of metaphysical "spark" required to ignite consciousness (which, just to be clear, I personally don't subscribe to, but it's beyond the point) - just because the brain is affected by physical factors doesn't prove it is ONLY physical factors that are at play. It doesn't demonstrate that they have a monopoly.
The big question persists: how does it happen that a computational system, no matter how complex, FEELS something?

You can also get it to agree that it is not conscious. I can write a one line program that claims to be conscious right now. Lamda and GTP-3 are amazing achievements, but they're still just chat bots that look good when they're being lobbed softball questions. If you ask something that maps to the input texts they're trained on you get credible looking responses, but critical or adversarial questioning very easily ex…
Turing's original paper is worth a read here. He already pre-empted a lot of the objections back then. You are right that Turing's original test is much harder than just passing a few shallow softball questions. See https://academic.oup.com/mind/article/LIX/236/433/986238 for the original paper. However, I do count responding well to softball questions as important markers of our progress. Ten years ago, no one was a…

Alas, if you refer to Searle's Chinese Room, that hasn't shown anything, if you just bite the bullet and accept that the Room is conscious.
I know Searle replied to this, but don’t remember what he said, except it seemed a little ridiculous to talk about sentient rooms. I think it’s much more plausible to just claim that the people who wrote the instructions know Chinese.
That's part of the sleight of hand employed in the argument, of reducing it to one person in a room with a table stacked with symbols in front of them. He's misdirecting our intuition with a trick of scale. If instead I said the "room" was the size of Jupiter, and it had a vast army of people manipulating the symbols, and each input and output took millions of years (or you speed up the rate of manipulation arbitrarily), all of a sudden it seems less implausible.

> You cite the primacy of sensation, but what more is sensation than a message from the sensory organ to the brain. This is false, it's a version of the homunculus fallacy. A sensory organ is something that connects the brain to the physical world. Even if you chose to model it as a an agent that sends messages to the brain, it is an agent of a different nature. The sensory agent doesn't receive messages from other a…
Where do you draw the distinction between "messages" and "information" (raw or cooked). Information theory was contrived to model messages sent in a noisy channel, but it applies just as well to data streams that have no communicative intent or origin. Its a distinction without a difference. You may as well treat all information as messages in a channel, even if the sender is nature herself. Alternatively, you may as well treat all messages as just information, and view "senders" with "intent" as just another physical process in a world of physical computation. As the cliche saying goes, "information is physical".
>We could perhaps come to agree upon some imagined world, but that could change arbitrarily much from one day to the next on a whim.
Ok, this is a fine basis to work with. How about this. "Reality is the set of beliefs which, if you disagree with them too much and for too long, you are eventually and permanently removed from the conversation." For example, quite recently, large swaths of people held an exquisite referendum on the existence of covid. Needless to say, rather than covid disappearing on their whim, a great deal of them are now permanently no longer participants in this conversation.
Notice this isn't far off from my original postulate. "Whatever we agree upon is our reality, and we'll argue with/fight anyone who disagrees until they agree with us or us with them." Allowing for some personification I could phrase this scenario as "they disagreed with the virus and the virus won."
So perhaps I do need to add one thing to the postulates. One thing which remains objectively true even in the conversational model of reality.
"You can die. Dying means never being heard from in this conversation again."
You're right there's no mechanism for any choice of words to win over any other choice of words without an objective consequence to losing. The things that exist so far are "you", "me", "this" and "death". Not where I was expecting this to go but good point.
