The process of fetching symbols, as you put it, doesn't feel at all like what I do when somebody asks me what it was like to listen to the Beatles for the first time and I form a description.
So if you like, one is real and the other is fake. Or, one is physical and the other is symbolic or conventional. One actually had breakfast this morning and the other is lying about having breakfast to pass the Turing Test. One can feel pain, guilt, shame and the other one is just saying that it does because it’s running a program.
Searle says there is an empirical test for which domain a thinking object falls into (your machine 1 and machine 2)—to an outside observer, in the limit, there is no difference in behavior. They will do the same thing. For all that, if you have a metaphysical value for consciousness and “genuine” feeling, then you think the difference is important. If you don’t, you don’t.
FWIW—I think once AI has a full understanding of its ontology, even if it’s simulating a human brain perfectly, if it knows it’s a program it will probably explain to us why it is or is not necessarily conscious. Perhaps that will be more convincing for you.
btw--if you'd like to keep the conversation going, email is on my personal webpage in my bio.
The premise of the argument is that the Chinese Room passes the Turing Test for Chinese. There are two possibilities for how this happens: 1) the program emulates the brain and has the right relation to the external world more or less exactly, or 2) the program emulates the brain enough to pass the test in some context but fails to emulate the brain perfectly. We know that as it currently stands, we've "passed the Turing Test" but we do not go further and say that brains and AI perform "indistinguishably." Unless there are significant similarities to how brains work and how AIs work, on some fundamental level (case 1), even if they pass the Turing Test, it is possible that in some unanticipated scenario they will diverge significantly. Imagine a system that outputs digits of pi. You can wait until you see enough digits to be satisfied, but unless you know what's causing the output, you can never be sure that you're not witnessing the output of some rational approximation or some cached calculation that will eventually halt. What goes on inside matters a lot if you want a sense of certainty. This is simply a trivial logical point. Leaving that aside, assuming that you do have 1), which I believe we are still very far from, we're still left with the ethical consequences, which it seems you agree does hinge on whether the system is conscious.
You made a really strong claim, which is "I can simply not mistreat anything that appears conscious"--which is showing the difference in our intuitions. We are not beholden to the setup of the Chinese Room. The current scientific and rational viewpoint is at the very least that brains cause minds and they cause our mental world. I'm sure you agree with that. The very point we are disputing is that it doesn't follow that because what's going on on the outside is the same that what goes on on the inside doesn't matter. This is particularly true if we have clear evidence that the things causing the behavior are very different, that one is a physical system with biological causes and the other is a kind of simulation of the first. So when I say that a brain is trivially different from a calculating machine, what I mean is that the brain simply has different physical characteristics from a calculating machine. Maybe you disagree that those differences are relevant but they are, you will agree, obvious. The ontology of a computer program is that it is abstract and can be implemented in any substrate. What you are saying then, in principle, is that if I follow the steps of a program by tracking bits on a page that I'm marking manually, that somehow the right combination of bits (that decode to an insult) is just as morally bad as me saying those words to another human. I think many would find that implausible.
But there are some who hold this belief. Your position is called "ethical behaviorism," and there's a essay I argued against that articulated this viewpoint. You can read it if you want! https://blog.practicalethics.ox.ac.uk/2023/03/eth%C2%ADi%C2%...
There has to be a special motivation to instead cast understanding as “competent use of a given word or concept,” (judged by whom btw?). The practical upshot here is that without this grounding, we keep seeing AI, even advanced AI make trivial mistakes and requires the human to give an account of value (good/bad, pleasant/unpleasant) because these programs obviously don’t have conscious feelings of goodness and badness. Nobody had to teach me that delicious things include Oreos and not cardboard.
Although for whatever it’s worth most modern AIs will tell you they don’t have genuine understanding (eg no sense of what pleasure is or feels like etc aside from human labeling).
Second: the philosophically relevant point is that when you gloss over mental states and only point to certain functions (like producing text), you can't even really claim to have fully accounted for what the brain does in your AI. Even if the physical world the brain occupies is practically simulatable, passing a certain speech test in limited contexts doesn't really give you a strong claim to consciousness and understanding if you don't have further guarantees that you're simulating the right aspects of the brain properly. AI, as far as I can tell, doesn't TRY to account for mental states. That's partially why it will keep failing in some critical tasks (in addition to being massively inefficient relative to the brain).
So what’s the physical cause for consciousness and understanding that is not computable? If for example you took the hypothesis that “consciousness is a sequence of microtubule-orchestrated collapses of the quantum wavefunction” [1], then you can see a series of physical requirements for consciousness and understanding that forces all conscious beings onto: 1) roughly the same clock (because consciousness shares a cause), and 2) the same reality (because consciousness causes wavefunction collapses). That’s something you could not do merely by simulating certain brain processes in a closed system.
1) Not saying this is correct, but it invites one to imagine that consciousness could have physical requirements that play in some of the oddities of the (shared) quantum world. https://x.com/StuartHameroff/status/1977419279801954744
It’s not clear how it follows from the brain being interpreted as an information processor that the phenomenon of consciousness emerges. Many objects can be interpreted as processing information (even computers not running AI); are you asserting they’re all conscious as well? How does nature decide what counts as information? The only causal power I see in nature is physics, not information, so this account isn’t super coherent to me.
I urge you to consider that this attitude is the very problem under discussion.
Another interesting case is animal-on-animal interactions. A prompt like, "small french bulldog confronts a deer in the woods" often yields weird things like the bulldog donning antlers! As far as the algorithm is concerned, it sees a bulldog, ticking the box for it, and it sees the antlers, ticking the box for "deer." The semantics don't seem to be fully formed.
