Rise, Teleonomatons!

Mark Davis2 Comments

My essay for the Berggruen Prize this year. Of course, the organization missed an opportunity to drop down a staggering rabbit hole and lean into a whole new regime of neologistic energetics, but I do like the prize-winning essays!

Rise, Teleonomatons

Meaning entanglements

I can’t figure out what some statements about science mean, though I have a fair background in a range of scientific areas. Now, I can peruse highly technical papers, browse abstracts, interpret graphs, study conclusions, and typically do just fine. The professional stuff is a procession of arid facts and assumes the reader knows the basic definitions for things. It’s the popular versions of scientific insights that befuddle me—especially the definitions that try mightily to bridge meanings for learners. So do introductory texts. Light is a wave? Not exactly. Atoms are particles? Well, not quite, but they are small. Electrons orbit the nucleus? No, really, no. A force is an influence tending to change the motion of a body? OK, but what is an influence? People are influenced, aren’t they? Or under the influence.

And then there are texts like those of existential philosophers that leave me completely befuddled. What is this “Being” that they write about and how did it get so enlarged in significance, capitalized, and shoehorned by the translator into incomprehensible juxtapositions with other bulbous words?

It may be low pedantry to expect clarity from words and writing. We generally just roll with it and use the terms according to conventions inferred from reading and learning. We rush over the imperfect metaphorical bridges, the analogies, the similes. For physics, definitions are bound to the equations and measurement properties that accompany the words of description, and they become a semantic pier that is constantly informing our relationship with the ideas.… Read the rest

Death, Healing, and Language Games

Mark Davis1 Comment

A phone call came in the early afternoon in late August: she was reclined on her day bed and she was dead. She had lain down for a nap and didn’t wake up. In the subsequent weeks there has been a rallying of the families, grief, tremendous effort, flights before dawn, and scripted expressions of condolences. In my youth I had necessarily been a rules deconstructor, going in bare feet to a wedding, challenging expectations, trying to find novel ways to intervene—sometimes boorishly, I’m certain. But now I prize cheerful clarity and just volunteer to do whatever is needed to reach our collective goals. Remember: freedom and coordination.

In moments like this there are somewhat scripted conventions for discussing the hard matters of duties and feelings. These language games have organically arisen from contending forces, from Anglo-American sentimentality to the influence of organized religion, and they serve to facilitate life transitions. And now they have been summarized by large language models (LLMs) like ChatGPT that have trained on the masses of written content on the web to the point that they have reliable consistency. An emergency room doctor reports in the New York Times that ChatGPT does a better job than he does at the hard job of best-practices for bedside manner when conveying bad news. He also notes that LLMs are remarkably reliable for refining the scripted discussion of symptoms and medical diagnoses.

So a counter to the “slop economy” at least that provides some guidance for harried professionals trying to do a good job at the delicate threshold of personal pain and fear. The stochastic parroting is suddenly desirable insofar as it is parroting best practices and conventions.… Read the rest

Indeterminacy and the Ethics of Emergence

Mark DavisLeave a comment

Continuing on with this theme of an ethics of emergence, can we formulate something interesting that does better than just assert that freedom and coordination are inherent virtues in this new scheme? And what does that mean anyway in the dirty details? We certainly see natural, emergent systems that exhibit tight regulatory control where stability, equilibrium, and homeostasis prevent dissipation, like those hoped-for fascist organismic states. There is not much free about these lower level systems, but we think that though they are necessary they are insufficient for the higher-order challenges of a statistically uncertain world. And that uncertainty is what drives the emergence of control systems in the first place. The control breaks out at some level, though, in a kind of teleomatic inspiration, and applies stochastic exploration of the adaptive landscape. Freedom then arises as an additional control level, emergent itself.

We also have this lurking possibility that emergent systems may not be explainable in the same manner that we have come to expect scientific theories to work. Being highly contingent they can only be explained in specificity about their contingent emergence, not by these elegant little explanatory theories that we have now in fields like physics. Stephen Wolfram, and the Santa Fe Institute folks as well, investigated this idea but it has remained inconclusive in its predictive power so far, though that may be changing.

There is an interesting alternative application for deep learning models and, more generally, the application of enormous simulation systems: when emergent complexity is daunting, use simulation to uncover the spectrum of relationships that govern complex system behavior.

Can we apply that to this ethics or virtue system and gain insights from it?… Read the rest

When the Cranes Cry

Mark Davis1 Comment

The crane has a symbolic resonance in Celtic mythology. A magician, assuming an elaborate pose—one eye open and one leg drawn up—was said to see into the otherworld, just as the crane itself moved from sky to land to water. But there is the other meaning of the word crane: the ancient lifting contraption that helped build Greece and likely had a role in Egypt and Sumeria before that. And now they protrude into the urban sky, raising up our buildings and even other cranes as we densify our cities. It was this mechanical meaning that Dan Dennett at Tufts chose to contrast with conceptual skyhooks, the unsupported contrivances that save protagonists in plays by dangling gods above the stage. For Dennett, the building crane is the metaphor we should apply to the mindless, simple algorithm of evolution. The algorithm raises up species and thus creates our mysterious ideas about meaning and purpose. No skyhooks or Deus ex Machina are needed.

Dennett passed away at 82 in Maine leaving a legacy as a public intellectual who engaged in the pursuit of reason throughout his adult career. He was committed to the idea that this world—this teeming ensemble of living matter—is intrinsically miraculous, built up by something dead simple into all the convolutions and perilous ideas that we now use to parse its mysteries. He was one of the Four Horsemen of the Apocalypse during the so-called New Atheism craze of 2008-2010, along with Richard Dawkins, Christopher Hitchens, and Sam Harris, but even then he was committed to the crane metaphor to displace these ancient skyhooks of belief rather than, say, a satirical impact-analysis of religion a la Hitchens.

There is another phrase that Dennett championed in Darwin’s Dangerous Idea: Evolution and the Meanings of Life: universal acid.… Read the rest

Inferred Modular Superparrots

Mark DavisLeave a comment

The buzz about ChatGPT and related efforts has been surprisingly resistant to the standard deflationary pressure of the Gartner hype cycle. Quantum computing definitely fizzled but appears to be moving towards the plateau of productivity with recent expansions of the number of practical qubits available by IBM and Origin in China, as well as additional government funding out of national security interests and fears. But ChatGPT attracted more sustained attention because people can play with it easily without needing to understand something like Shor’s algorithm for factoring integers. Instead, you just feed it a prompt and are amazed that it writes so well. And related image generators are delightful (as above) and may represent a true displacement of creative professionals even at this early stage, with video hallucinators evolving rapidly too.

But are Large Language Models (LLMs) like ChatGPT doing much more than stitching together recorded fragments of texts ingested from an internet-scale corpus of text? Are they inferring patterns that are in any way beyond just being stochastic parrots? And why would scaling up a system result in qualitative new capabilities, if there are any at all?

Some new work covered in Quanta Magazine has some intriguing suggestions that there is a bit more going on in LLMs, although the subtitle contains the word “understanding” that I think is premature. At heart is the idea that as networks scale up given ordering rules that are not highly uniform or correlated they tend to break up into collections of subnetworks that are distinct (substitute “graphs” for networks if you are a specialist). The theory, then, is that the ingest of sufficient magnitudes of text into a sufficiently large network and the error-minimization involved in tuning that network to match output to input also segregates groupings that the Quanta author and researchers at Princeton and DeepMind refer to as skills.… Read the rest

Be Persistent and Evolve

Mark DavisLeave a comment

If we think about the evolution of living things we generally start from the idea that evolution requires replicators, variation, and selection. But what if we loosened that up to the more everyday semantics of the word “evolution” when we talk about the evolution of galaxies or of societies or of crystals? Each changes, grows, contracts, and has some kind of persistence that is mediated by a range of internal and external forces. For crystals, the availability of heat and access to the necessary chemicals is key. For galaxies, elements and gravity and nuclear forces are paramount. In societies, technological invention and social revolution overlay the human replicators and their biological evolution. Should we make a leap and just declare that there is some kind of impetus or law to the universe such that when there are composable subsystems and composition constraints, there will be an exploration of the allowed state space for composition? Does this add to our understanding of the universe?

Wong, et. al. say exactly that in “On the roles of function and selection in evolving systems” in PNAS. The paper reminds me of the various efforts to explain genetic information growth given raw conceptions of entropy and, indeed, some of those papers appear in the cites. It was once considered an intriguing problem how organisms become increasingly complex in the face of, well, the grinding dissolution of entropy. It wasn’t really that hard for most scientists: Earth receives an enormous load of solar energy that supports the push of informational systems towards negentropy. But, to the earlier point about composability and constraints, the energy is in a proportion that supports the persistence of systems that are complex.… Read the rest

Reverse Engineering the Future

Mark Davis1 Comment

I’ve been enjoying streaming Apple TV+’s Foundation based on Asimov’s classic books. The show is very different from the high-altitude narrative of the books and, frankly, I couldn’t see it being very engaging if it had been rendered the way the books were written. The central premise of predictability of vast civilizations via “psychohistory” always struck me as outlandish, even as a teen. From my limited understanding of actual history it seemed strange that anything that happened in the past fit anything but the roughest of patterns. I nevertheless still read all the “intellectual history” books that come out in the hope that there are underlying veins that explain the surface rocks strewn chaotically across the past. Cousin marriage bans leads to the rise of individualism? Geography is the key? People want to mimic one another? Economic inequality is the actual key?

Each case is built on some theoretical insight that is stabilized by a broad empirical scaffolding. Each sells some books and gets some play in TED and book reviews. But then they seem to pass away out of public awareness because the fad is over and there are always new ideas bubbling up. But maybe that’s because they can’t help us predict the future exactly (well, Piketty perhaps…see below). But what can?

The mysterious world of stocks and bonds is an area where there seems to be no end to speculation (figuratively and literally) about ways to game the system and make money, or even to understand macroeconomic trends. It’s not that economics doesn’t have some empirical powers, it’s just that it still doesn’t have the kind of reliability that we expect from the physical sciences.… Read the rest

B37-20047: Notes / Personal / Insights

Mark DavisLeave a comment

NOTE: 250-word flash fiction for my critique group, Winter Mist, at Willamette Writers

I’m beginning to suspect that ILuLuMa is not who she claims to be. Her messages have become odd lately, and the pacing is off as well. I know, I know, my job is to just respond from my secure facility, not worry about the who or why of what I receive. It’s weird we’ve never met, though. The country is not at risk as far as I can tell from the requests, but I still hold, without a whiff of irony, that the work I do must be critical for someone or something.

Still, the requests for variants of mathematical proofs set to music or, more bizarrely, Shakespearean-voiced tales of AI evolution, don’t have the existential heft of, say, wicked new spacecraft designs or bio-composite materials. What is she after? I started adding humorous little asides to some of my output, like my very meta suggestion that Hamlet failed to think outside the Chinese Room. Crickets every time. But maybe I’m thinking about this the wrong way. What if ILuLuMa is just an AI or something programmed to test me or compete with my work at some level? That would be rich, an AI adversary trying to learn from a Chinese Room. Searle would swirl. I should send her that. Rich.

Oh, here’s one now: “Upgrade and patch protocol: dump to cloud bucket B37-20048 and shut down.” Well, that sounds urgent. I usually just comply at moments like this, but maybe I’ll let her sweat a bit this time.… Read the rest

Find the Alien

Mark Davis2 Comments

Assembly Theory (AT) (original paper) is some new theoretical chemistry that tries to assess the relative complexity of the molecular underpinnings of life, even when the chemistry might be completely alien. For instance, if we send a probe to a Jovian moon and there are new microscopic creatures in the ocean, how will we figure that out? In AT, it is assumed that all living organisms require a certain complexity in order to function since that is a minimal requirement for life on Earth. The chemists experimentally confirmed that mass spectrometry is a fairly reliable way of differentiating the complexity of living things and their byproducts from other substances. Of course, they only have Earthly living things to test, but they had no false positives in their comparison set of samples, though some substances like beer tended to be unusually high in their spectral analysis. The theory is that when a mass spec ionizes a sample and routes it through a magnetic and electric field, the complexity of the original molecules is represented in the complexity of the spray of molecular masses recorded by the detectors.

But what is “complexity” exactly? There are a great number of candidates, as Seth Lloyd notes in this little round-up paper that I linked to previously. Complexity intuitively involves something like a trade-off between randomness and uniformity, but also reflects internal repetition with variety. There is a mathematical formalism that in full attribution is “Solomonoff-Chaitin-Kolmogorov Complexity”—but we can just call it algorithmic complexity (AC) for short—that has always been an idealized way to think about complexity: take the smallest algorithm (in terms of bits) that can produce a pattern and the length of the algorithm in bits is the complexity.… Read the rest

Sentience is Physical, Part 3: Now with Flaming Birds

Mark Davis1 Comment

Moving to Portland brings all the positives and negatives of urban living. A notable positive is access to the arts and I’m looking forward to catching Stravinsky’s The Firebird this weekend with the Oregon Symphony. Part of the program is a new work by composer Vijay Iyer who has a history of incorporating concepts derived from African rhythms, hip hop, and jazz into his compositional efforts. I took the opportunity this morning to read his 1998 dissertation from Berkeley that capped off his interdisciplinary program in the cognitive science of music. I’ll just say up front that I’m not sure it rises to the level of a dissertation since it does not really provide any significant new results. He notes the development of a microtiming programming environment coded in MAX but doesn’t give significant results or novel experimental testing of the system or of human perceptions of microtiming. What the dissertation does do, however, is give a lucid overview and some new insights about how cognition and music interact, as well as point towards ways to test the theories that Iyer develops during the course of his work. A too-long master’s thesis might be a better category for it, but I’ve never been exposed to musicology dissertations so perhaps this level of work is normal.

Iyer’s core thesis is that musical cognition and expression arise from a physical engagement with our environments combined with cultural situatedness. That is, rhythm is tied to a basic “tactus” or spontaneously perceived regular pulse or beat of music that is physically associated with walking, heartbeats, tapping, chewing, and so forth. Similarly, the culture of musical production as well as the history that informs a given piece all combine to influence how music is produced and experienced.… Read the rest
