My guess is that the ones that will keep it going are those who's valuation is still semi-related to actual profits (Google, Meta, etc.), so I would guess something like pytorch will be maintained? But, I fully expect massively overvalued companies like OpenAI and Palantir to engage in big cuts.
Blake Richards (@tyrellturing.bsky.social) reply parent
I think the *market* bubble will likely burst (the valuations of some of these companies are ridiculous), but like the dotcom bust, I don't think that market correction will actually see the end of the rapid growth of use of AI in many sectors of the economy.

Positive tipping points for climate, like the UK phasing out coal, show how big steps toward a low-carbon future can suddenly become unstoppable. Can we identify where the next tipping points could happen, and figure out how to help trigger them? These researchers say YES. Read more:

Indeed, I think this is the correct answer. Basically, the markets are interpreting this as mostly theatre where the probability of true loss of independence are small.

Great thread, spot on. I fully agree: We can't really know, so that's the only really correct answer. But, we can say that, unlike a chair, LLMs exhibit behaviours that often lead us to infer consciousness in other agents, so it's not quite as easy to say "it's almost assuredly not conscious".

Yes, I 100% agree! It will require a big mind shift from the 20th century paradigm of how we use computing in business.
Blake Richards (@tyrellturing.bsky.social) reply parent
I'm willing to bet that generative AI will be the same - most companies won't adopt it for a while because it won't actually make sense given how they currently work. But, that's not because it doesn't work - it's because it will only become useful after certain shifts in the economy.
Blake Richards (@tyrellturing.bsky.social) reply parent
As a result, tractors only got widely adopted when society was fully industrialized and farms shifted from being the thing that the average person did on a small plot of land to something done on huge plots of land where ploughing and seeding needed to be mechanized.
Blake Richards (@tyrellturing.bsky.social) reply parent
I like to use the analogy with the tractor: Tractors existed for decades before farmers started using them widely. Why? Was it because tractors were just pure hype? No, of course not. Rather, tractors only made sense with huge, industrial-scale farms, not small family holdings.
Blake Richards (@tyrellturing.bsky.social)
I've gotta comment on this: A lot of people on BlueSkyhere think this is evidence that generative AI isn't useful, but that's not necessarily the correct conclusion, IMO. What this may tell us is that generative AI is not something you can just add onto existing company systems as is. #MLSky
Blake Richards (@tyrellturing.bsky.social) reply parent
But note: We don´t need a definition of "alive" to make progress in biology, indeed, we've been operating without one for the entirety of the field's history! Which shows that the desire for a tighter/more generative definition is not always driven by scientific need.

Indeed, you do! But as you will see in our commentary, I think your framing of computationalism is overly restrictive, Anil, i.e., I think many things you frame as being non-computational are readily cast in a computational light.
Blake Richards (@tyrellturing.bsky.social) reply parent
Right, but then the answer obviously just hinges on: Do you believe that the category "living thing" can only be applied to entities who have a physical existence like ours?
Blake Richards (@tyrellturing.bsky.social) reply parent
Blake Richards (@tyrellturing.bsky.social) reply parent
I don't think "alive" is a property that exists as some sort of universal truth, its a concept we use to describe some systems. It would be up to use to decide whether this simulation meets the conditions for what we wish to call "alive", and we either could or couldn't.
Blake Richards (@tyrellturing.bsky.social) reply parent
The mind, life, physics, and so on are computational systems if we want to frame them that way. I think anyone who paints "computational" as an ontological label that is true independent of us is not fully understanding the realities of how we use this concept in science (and math).
Blake Richards (@tyrellturing.bsky.social) reply parent
Sorry, but I don't see the analogy... The luminiferous aether was a specific theory about the structure of the world. In contrast, computationalism is a methodological approach, a way of analyzing a system - it is not a theory about what exists in the world. (That's the core of my point.)
Blake Richards (@tyrellturing.bsky.social) reply parent
Yeah, you've told me this, but I remain skeptical, as I've never found the arugments against computational functionalism to hold merit... I'll have to get you to explain to me where you see validity to these arguments over a beer sometime - it's surely too involved a discussion for social media. 🙂
Blake Richards (@tyrellturing.bsky.social) reply parent
Looking forward to seeing your commentary!
Blake Richards (@tyrellturing.bsky.social) reply parent
Ah, well, quite. I think some of these authors are either misguided (Searle), or misconstruing computationalism (Seth). I've actually just submitted a BBS response to Seth's latest piece that makes precisely this argument. 🙂
Blake Richards (@tyrellturing.bsky.social) reply parent
Hmmm... interesting. I would say that natural selection theory is rife with teleological ideas, no?
Blake Richards (@tyrellturing.bsky.social) reply parent
My point was not that other scientific disciplines also frame things in terms of computation. My point was that other disciplines are comfortable with the idea that we use a given approach/idea for its methodological, rather than philosophical, merit (e.g. natural selection isn't for metaphysics).
Blake Richards (@tyrellturing.bsky.social) reply parent
💯
Blake Richards (@tyrellturing.bsky.social) reply parent
But, I would argue almost all science is like that anyway, uncontroversially so. It's only in neuroscience, and maybe quantum mechanics, that people seem to think science should somehow be doing philosophers' jobs. 😜
Blake Richards (@tyrellturing.bsky.social) reply parent
Very funny... 😂 But, I think it misses the mark. The computational explanations provide many useful things, including the ability to simulate the system in question! What they don't provide is an answer to is any of the philosophy of mind questions that people are interested in.
Blake Richards (@tyrellturing.bsky.social) reply parent
Yeah, agreed! I personally am more comfortable with a framing along the lines of "computationally modelling" or "computational analyses" of the brain.
Blake Richards (@tyrellturing.bsky.social) reply parent
What if I don't want to touch metaphysics? What if my goal when using the term "compute" is not philosophical, but practical and methodological? Then Piccinini's objections are not relevant, I would say...
Blake Richards (@tyrellturing.bsky.social) reply parent
Indeed, in the article you linked, @wiringthebrain.bsky.social, I note that the following line in the abstract: "If we want to improve our understanding of both the metaphysics of mental states and the functional relations between them, we should reject these assumptions."
Blake Richards (@tyrellturing.bsky.social) reply parent
So, when we talk about the brain "computing", we're highlighting the methodological and epistemic strategies we're employing to explain the system. But, we're not making some claim about the ontology or metaphysics of the brain.
Blake Richards (@tyrellturing.bsky.social) reply parent
Yeah, I know many people who agree with this statement, but I don't think it's quite true. The utility of the term lies not in demarcating that which computes from that which doesn't. The utility lies in identifying the approach we take to studying the phenomenon we are labelling as "computation".
Blake Richards (@tyrellturing.bsky.social) reply parent
Yeah, TBH, I don't even really know what "non-computational functionalism" means, @wiringthebrain.bsky.social... 😅 tl;dr: Dynamical systems are a form of computation!!!

I think this relates to the underlying philosophy implicitly expressed by the methodologies. When you're used to studying equations of interacting units, emergence is a key, obvious idea. When you're used to trying to break everything down to the molecular mechanisms, it seems radical.
Blake Richards (@tyrellturing.bsky.social)
Interesting thread here. When "emergence" is discussed in neuroscience, I find the most salient predictor of people's perspectives is their training. Computational people are often like, "Emergence? Of course, no shit." Biologists in contrast seem to often view this as a novel stance. 🧠📈 🧪
Blake Richards (@tyrellturing.bsky.social) reply parent
Yeah, I see where you're going, but I would argue a good LLM is more like a sous-chef: it does a lot more than help you with one function (heating things up), its more like an extra pair of hands. If you're using an LLM like a microwave you're doing it wrong. 😜
Blake Richards (@tyrellturing.bsky.social) reply parent
+1 Emergence in the sense of a system not being predictable/knowable simply from the constituent parts is a solid idea that helps explain a lot of complex natural phenomena. Emergence as an extra layer of ontology separate from the lower layer is essentially religion dressed in scientific disguise.

Me too. I see a lot of hidden magical thinking in many of the discussions in these areas, both on emergence and consciousness.

Blaise Aguera y Arcas and I have submitted a commentary on that BBS piece. tl;dr: I think Anil's theory is actually computational, he just doesn't want to admit it. Alternatively, he is appealing to bio-magic (which I will give him the benefit of the doubt that he's not).

Wouldn't that depend on the specifics of the cost/difficulty of the intervention? Like, hypothetically, suppose that PSA screening cost pennies and could be done by yourself at home. Wouldn't it be good to have everyone with a potential genetic risk do it, even though it was useless for many?

Yeah, that wasn't my quesiton. I understand the point that for a specific sample the differences may be due almost entirely to the environment. My point was that we can make inferences about what it will be for individual samples *on average*.

No, I think it's correct... Your example of malnourishment is also correct, but that doesn't counter what I said. For every sample where it was pure environment, there would be a sample where it was pure genetics, so on average the statement would hold.

This may actually be a frequentist versus Bayesian thing here. From a Bayesian perspective, I can say something about my confidence that something will hold for the individual samples. But, for a frequentist, I can only ever say something about how often I will get those results from the samples.

Hmmm... I feel like there's a philosophical point of divergence here. Sure, for a given draw I can't use this to make a concrete statement, but before I make the draw, I can use the population level stats to make predictions about what I will observe for the individuals. Is that not meaningful?
