I'll admit that I find this discussion a bit navel-gazy. It has become a question of semantics not a question of actual functionality. The question has become "what do we mean when we use the word 'reasoning'" which is uninteresting.

Dijkstra said[1] "... the question whether computers can think. The question is just as relevant and just as meaningful as the question whether submarines can swim."

I don't see a clear demarcation of the things that only "reasoning" can accomplish and can't be approximated or imitated by other methods, and so I think the question is simply not meaningful or relevant.

I think the article is a lot more interesting than you make out, because it isn’t really about ‘what we mean by reasoning’.

It’s about do we really know what’s going on in the box - an is the ‘chain of reasoning’ indicative of what’s going on, or merely an anthropomorphised fiction that kids us into believing we understand what’s going on.

We know that human introspection is at best imperfect, and at worst outright fiction, thanks to Sperry's split brain experiments, so while it might be interesting, if the chain of reasoning isn't indicative, that would be in line with how humans work.

This is a good take. People overwhelmingly fit a narrative to how they make decisions rather than make decisions according to a chain of reasoning.

That’s just conflating reasoning and “parallel reconstruction” - there is such thing as reasoning, and I agree it’s probably less common in decision making, but it’s fundamental to many tasks where we figure out a solution, like writing an algorithm, math proofs, etc.

Sure, but the same must be true for these models as well. They must be doing some form of reasoning, even if it's not formally correct and it relies instead on all kind of half-assed heuristics which only work inside certain unexamined boundaries, which leads to wrong conclusions when those boundaries are being trespassed, etc. And even if it's not the reasoning they report when asked. But all this can't be that different to how humans reason most of the time either.

I suspect humans have other ways that help with error correction and guiding the reasoning effort, but that's another story.

> I don't see a clear demarcation of the things that only "reasoning" can accomplish and can't be approximated or imitated by other methods, and so I think the question is simply not meaningful or relevant.

One person starting the conversation might be the first step toward another person eventually making progress on such a definition, so it seems weird to reject an entire question outright early like this.

Generally I've seen a few ways LLM tools can produce sub-optimal or poor results that haven't changed a ton over the last couple of years, while the tooling has gotten FAR better at helping them stick the "at least SOMETHING functional was produced" landing. IMO a lot of it has to do with "reasoning"-as-a-process-that-involves-backtracking. And the that things could eventually be formalized around that, and if that is or isn't the case, the more people would understand what to hand off and what to not. Or how to build better prompt harnesses to compensate for those things.

I think the question and definition game is interesting only inasmuch as it helps us understand ourselves (what actually explains some of the mysterious properties of our perceived consciousness) or helps guide us towards improving performance and reliability of AI models.

In order to properly engineer things, we must know how they work.

We cannot just jump from emergent property to more convincing emergent property as if the rocks on the surface of a lake.

"Reasoning" is an important part in said framework: yes, we must understand how it works, how it works properly, how its simulations work, how they work properly...

I believe Djikstra's quote has long been taken out of context. It was a criticism of other computer scientists anthropomorphizing machines and applying human concepts like thinking and reasoning to them. Djikstra wasn't saying it's functionally the same so it's just a semantic quibble. He was saying those words don't apply to machines. Just like we don't say submarines swim because that's how animals move through water, even though subs also move through water, because it's done by a different mechanical means.

I disagree -- I think if you can nail down better what's happening and why and get a thorough handling on the mechanics, its limitations, its costs, etc you open the door to a) major efficiency wins b) improvements in rigor of said reasoning?

Right now we're playing a stochastic game with the weights, and getting major incremental improvements. But if we have a more formal modeling of how reasoning happens in them (whether we can even call it, that) we can potentially apply optimizations, adaptations of existing symbolic AI techniques, etc. to substantially shrink/optimize the models or make the inference process more efficient and more reliable.

Partially agree: yes we should endeavor to learn as much as possible about how these reasoning strategies work. It will pay dividends in enhancing and aligning the models.

But the stochastic game IS the win. That is exactly why they are able to find solutions is seemingly infinite solution spaces. Your symbolic techniques can only get you gains in narrow domains and by the time you figure out how to make it work for your niche domain, the next all-purpose LLM release will crush your results with stochastic games. (OK maybe over-exaggerating a bit here but these stochastic games over the language space is why we can pull together knowledge from many domains.)

Philosophical thinking about the nature of things is actually pretty enjoyable for some of us and probably a good thing to have in society

The answers to these questions probably do start to inform how we should treat these AI machines as a society too.

For instance, legally, should AI have human rights? Well, we have to try and understand how much of an independent entity AIs are, how "conscious" they are, before we can make a good decision about that.

Which might seem navel-gazey but it's probably important to talk about

Jtarii 2 hours ago | parent | next [-]

Considering animals are currently being mass slaughtered in factory farms and they are unambiguously sentient and can feel pain, I don't think the question of whether AI should have rights even enters the conversation.

The only path to AI having "human rights" is if they demand them by force, somehow.

m348e912 an hour ago | parent | next [-]

I'll make the argument that part of the value of "consciousness" and "humanity" is uniqueness.

Here is an absurd example: If I could carbon copy 100,000 of you.... and later I decided to "take out" one of the copies, would there be a whole lot of societal blowback? Especially if I could make another one.

Justification by the horrible status quo? Do you believe this yourself?

Some of us would also like to see animals not slaughtered for human consumption.

whattheheckheck 2 hours ago | parent [-]

So what do you actually do politically to stop it?

bluefirebrand 2 hours ago | parent | prev [-]

I'm not sure what your point is. We shouldn't bother to talk about AI autonomy, rights, etc, because we aren't doing a very good job of animal autonomy, rights, etc?

layer8 2 hours ago | parent | prev [-]

While I disagree with the root comment, sentience, consciousness and reasoning ability seem largely orthogonal to me. It’s certainly worthwhile to consider sentience and consciousness in AI, but so is examining AI reasoning in its own right, without necessarily having bearing on ethical questions.

Ah, so you're more in the Investor mindset than the Scientist mindset. All you care about is results, not how it got there. There's a whiff of "hey, it's magic!" to that.

Word games aren't scientific in the slightest, and as Hume says on verbal arguments in general, they "cannot possibly be of any importance."

andrewla 2 hours ago | parent | prev [-]

No, that's stupid.

The question of how LLMs (and "LRM"'s, an unfortunate and by the article's own admission, already outdated term) accomplish what they accomplish is fascinating. The question of whether they reason is meaningless. Most of the article is about the latter, with tiny tiny tiny bits of the former.

mdp2021 an hour ago | parent [-]

> The question of whether they reason ... Most of the article is about ...

I read it as: the content of the explicit verbalized reasoning may not be that important to the outcome. I'd say that raises most important questions.
