> That would be a silly argument because feelings involve qualia, which we do not currently know how to precisely define, recognize or measure.
If we can't define, recognize or measure them, how exactly do we know that AI doesn't have them?
I remain amazed that a whole branch of philosophy (aimed, theoretically, at describing exactly this moment of technological change) is showing itself up as a complete fraud. It's completely unable to describe the old world, much less provide insight into the new one.
I mean, come on. "We've got qualia!" is meaningless. Might as well respond with "Well, sure, but AI has furffle, which is isomporphic." Equally insightful, and easier to pronounce.

In the same way my digital thermometer doesn't have quaila. LLM's do not either. I really tire of this handwaving 'magic' concepts into LLM's.
Qualia being difficult to define and yet being such an immediate experience that we humans all know intimately and directly is quite literally the problem. Attempted definitions fall short and humans have tried and I mean really tried hard to solve this.

And I repeat the question: how do you know your thermometer doesn't? You don't, you're just declaring a fact you have no basis for knowing. That's fine if you want a job in a philosophy faculty, but it's worthless to people trying to understand AI. Again, c.f. furffle. Thermometers have that, you agree, right? Because you can't prove they don't.
You're just describing panpsychism, which itself is the subject of much critique due to its nonfalsifiability and lack of predictive power. Not to mention it ignores every lesson we've learned in cognition thus far.
A thermometer encoding "memory" of a temperature is completely different than a thermometer on a digital circuit, or a thermometer attached to a fully-developed mammalian brain. Only the latter of this set for sure has the required circuitry to produce qualia, at least as far as I can personally measure without invoking solipsism.
It's also very silly to proclaim that philosophy of mind is not applicable to increasingly complex thinking machines. That sounds like a failure to consider the bodies of work behind both philosophy of mind and machine cognition. Again, "AI" is ill-defined and your consistent usage of that phrase instead of something more precises suggests you still have a long journey ahead of you for "understanding AI".
God, can we fucking quit with this "philosophy is bullshit" stuff. Like there are literally Faculty in Philosophy all over the world trying to understand AI. Philosophy faculty do stuff, they try to understand things, most of the ideas we are talking about here came from philosophers.

The problem is that just like your digital thermometer, 50 human brain neurons in a petri dish "obviously" don't have qualia either.
So you end up either needing to draw a line somewhere between mechanical computation and qualia computation, or you can relegate it to supernatural (a soul) or grey areas (quantum magic).
What I'm trying to tease out is isn't an opinion alone. It's a generally understood problem in the scientific community. I'm highlighting it to illustrate the issues at hand.

Quite literally the jury is still out. It is a hotly debated topic approached from various angles. Arguments are nuanced which is why you fill find ideas such as panpsychism thrown into the mix. I hate appealing to authority but in this instance it is more than warranted. Humans have grappled with this for centuries and the problem hasn't gone away.

I think there are several lines. Phase changes happen relatively suddenly, when a system or subsystem reaches a critical threshold. The experience of "qualia" certainly involves many such phase changes as a complex, dynamical system grows in complexity while maintaining stability.
A sufficiently complex organism lacking eyes but having light-sensitive organs still experiences qualia if you define it the right way. But do they experience heartbreak like I do? It isn't an all-or-nothing situation, even if we don't yet know where these lines are.
This supports the idea that subjective consciousness emerges from complexity in systems that have sensory feedback loops. The simpler the system, the smaller the qualia space.
Have you considered that you just don't fully understand the literature? It's quite arrogant to write off the entire philosophy of mind as "a complete fraud".
> It's completely unable to describe the old world, much less provide insight into the new one.
What exactly were you expecting?
Philosophy is a science, the first in fact, and it follows a scientific method for asking and answering questions. Many of these problems are extremely hard and their questions are still yet unanswered, and many questions are still badly formed or predicated on unproven axioms. This is true for philosophy of mind. Many other scientific domains are similarly incomplete, and remain active areas of research and contemplation.
What are you adding to this research? I only see you complaining and hurling negative accusations, instead of actually critically engaging with any specifics of the material. Do you have a well-formed theory to replace philosophy of mind?
> I mean, come on. "We've got qualia!" is meaningless. Might as well respond with "Well, sure, but AI has furffle, which is isomporphic." Equally insightful, and easier to pronounce.
Do you understand what qualia is? Most philosophers still don't, and many actively work on the problem. Admitting that something is incomplete is what a proper scientist does. An admission of incompleteness is in no way evidence towards "fraud".
The most effective way to actually attack qualia would be to simply present it as unfalsifiable. And I'd agree with that. We might hopefully one day entirely replace the notion of qualia with something more precise and falsifiable.
But whatever it is, I am currently experiencing a subjective, conscious experience. I'm experiencing it right now, even if I cannot prove it or even if you do not believe me. You don't even need to believe I'm real at all. This entire universe could all just be in your head. Meanwhile, I like to review previous literature/discussions on consciousness and explore the phenomenon in my own way. And I believe that subjective, conscious experience requires certain elements, including a sensory feedback loop. I never said "AI can't experience qualia", I made an educated statement about the lack of certain components in current-generation models which imply to me the lack of an ability to "experience" anything at all, much less subjective consciousness and qualia.
Even "AI" is such a broadly defined term that such a statement is just ludicrous. Instead, I made precise observations and predictions based on my own knowledge and decade of experience as a machine learning practitioner and research engineer. The idea that machines of arbitrary complexity inherently can have the capability for subjective consciousness, and that specific baselines structures are not required, is on par with panpsychism, which is even more unfalsifiable and theoretical than the rest of philosophy of mind.
Hopefully, we will continue to get answers to these deep, seemingly unanswerable questions. Humans are stubborn like that. But your negative, vague approach to discourse here doesn't add anything substantial to the conversation.
I agree with your sentiments wholeheartedly.
I would add I find it difficult to understand why so few have even a basic level of philosophical understanding. The attitude of being entirely dismissive of it is the height of ignorance I'm sure. I would presume few would be able to define then what Science actually is.
So many of these kinds of people also struggle to realize they're invoking panpsychism with their arguments. They lack a framework for describing intelligence. Such a framework allows us to separate "intelligence" from "experience".
"Intelligence" in the universe is actually quite common, more common than life. You can argue that any stable, complex process exhibits intelligence. After all, it needs to be able to sample its internal and external environments and carry out physical computations in order to regulate itself and maintain stability. And we can interpret things like the good regulator theorem to argue that such complex dynamical systems must also maintain at least a partial memory/mapping of their environment. That mapping can live abstractly within the structure of system itself.
But what a stabilized solar system doesn't have is the incredibly complex neurochemical structures present in the brain which support the insanely rich experience I am having now. It's one thing for a system to classify and label colors by wavelength. It's quite another for me to "see" and experience red in my mind's eye. To activate related emotional pathways that I associate with various colors and shapes, which are exploited in signage and architectural design. I'm not claiming my experience is separate from simpler dynamic systems, but it's got magnitudes more going on. Layers upon layers of things such as archetypes and instinct which create a possibly emergent conscious experience.

> Philosophy is a science
Not according to Zombie Feynman it isn't[1] (someone else can dig up the link). Case in point:
> Do you understand what qualia is? Most philosophers still don't
It's a meaningless word. It's a word that gives some clean construction around closely-held opinions about how life/consciousness/intelligence/furffle/whatever works. So it's a valuable word within the jargon of the subculture that invented it.
But it's not "science", which isn't about words at all except as shorthand for abstractions that are confirmed by testable results.
"Qualia", basically, is best understood as ideology. It's a word that works like "woke" or "liberal" or "fascist" or "bourgeoisie" to flag priors about which you don't want to argue. In this case, you want people to be special, so you give them a special label and declare a priori that it's not subject to debate. But that label doesn't make them so.
[1] Of course. You can recursively solve this problem by redefining "science" to mean something else. But that remains very solidly in the "not science" category of discourse.
Have you considered the possibility that you're the one who's really committed to an outcome, and are desperately trying to discredit anything that contradicts it?

I think this is backwards, no? Science is a philosophy, not the other way around.

I'm sorry, but you clearly lack the most basic understanding of scientific history, and do not understand what philosophy even is.

> Aristotle pioneered scientific method in ancient Greece alongside his empirical biology and his work on logic, rejecting a purely deductive framework in favour of generalisations made from observations of nature.
Aristotle, the famous philosopher and mathematician.
If you cannot understand the very nature of where our modern scientific frameworks came from, how it relates to rationalism, itself a philosophical concept, then you cannot see that philosophy underpins every bit of science we have today. Philosophy gives us the tools to decide when to reasonably trust or distrust observations and intuitions. It is the foundational science that allows the rest of humanity's scientific research to be taken seriously.

This is so dumb. Qualia is just the name for a specific thing which we all (appear) to phenomenologically experience. You can deny it exists or deny its utility as a concept, but fundamentally its just an idea that philosophers (and scientists, I have to add) have found useful to pose certain other questions about the human condition, minds, brains, etc.
Your XKCD actually seems to make the opposite point. I can do a non-rigorous experiment with just one subject (me) that suggests Qualia exists. Finding ways to make this rigorous is difficult, of course, but its an observation about the nature of the world that it feels like something to experience things.
My point isn't that qualia is a good concept. I tend to be somewhat deflationary about it myself, but its not an ideology.
