How To Control A Population in Six Easy Steps


We have really got this thing figured out. And by we, I mean not you:

Coding differences in Medicare Advantage plans led to $33 billion in excess revenue to insurers
Apr 2025, phys.org

The analysis found that because of coding differences, the average Medicare Advantage risk score in 2021 was 0.19 higher than the average Traditional Medicare risk score and Medicare Advantage plans received an estimated $33 billion in additional revenue, with $13.9 billion, or 42% of the total, going to UnitedHealth Group. 

MA plans are paid more for sicker members and less for healthier members, providing an incentive for MA plans to report as many diagnoses as legitimately possible. 
("As many diagnoses as possible") 
The researchers found that the average MA risk score was 18.5% higher than the average TM risk score. 

Differential coding resulted in an estimated $33 billion in additional payments to MA plans in 2021, a $1,863 increase in revenue per UnitedHealth member, and substantially greater than the industry average of $1,220. 

Data came from Centers for Medicare and Medicaid Services Chronic Conditions Data Warehouse from 2015 to 2020 and the Master Beneficiary Summary Files from 2015 to 2021. The core analytic sample included 697 contracts that were active in 2021.

Quantum Phone Calls


AKA Schrodinger's Hype

Quantum hype will continue to appear in the news and advertising as if it were here already, and although it's not really "here", it sure is somewhere:

Researchers demonstrate the UK's first long-distance ultra-secure communication over a quantum network
Apr 2025, phys.org

Lists all the other quantum networks:

  • China recently set up a massive network that covers 4,600 kilometers by connecting five cities using both fiberoptics and satellites. (more details on this one below)
  • In Madrid, researchers created a smaller network with nine connection points that use different types of QKD to securely share information.
  • In 2019, researchers at Cambridge and Toshiba demonstrated a metro scale quantum network operating at record key rates of millions of key bits per second.
  • In 2020, researchers in Bristol built a network that could share entanglement between multiple users.
  • Similar quantum network trials have been demonstrated in Singapore, Italy and the U.S.
  • And now, from the Universities of Bristol and Cambridge and the Quantum Communications Hub project have created a long-distance network that can handle both types of QKD, entanglement distribution, and regular data transmission all at once.

World's first quantum microsatellite demonstrates secure communication with multiple ground stations
Mar 2025, phys.org

The team successfully launched Jinan-1, the world's first quantum microsatellite, on July 27, 2022. Additionally, the team developed compact optical ground stations in Jinan, Hefei, Nanshan, Wuhan, Beijing, Shanghai, in China, and Stellenbosch in South Africa. The satellite transmitted approximately 250 million quantum photons per second. For each satellite pass, the system generated up to 1 Mbits of secure keys. Using the satellite as a trusted relay, the team demonstrated successful secure key sharing and encrypted communication between Beijing and Stellenbosch—two cities separated by 12,900 km.

What Does It Mean To Be a Thing


For every thing, there is a fake. And for everything else, we just change the definition of what it means to be artificial until the fake thing is no longer considered fake:

Preventing counterfeiting by adding dye to liquid crystals to create uncrackable coded tags
Aug 2024, phys.org

They're creating anti-counterfeiting labels for high-value goods by mixing fluorescent dyes with cholesteric liquid crystals, which causes their helical structure to twist either left or right, thereby determining how the crystals reflect light, and producing a specific "light signature." Precise control over the twisting and the resulting light patterns makes these labels almost impossible to counterfeit.

'World first' ruby grown in jewellery setting in lab
Sep 2024, BBC News

A tiny fragment of real ruby is grown in a furnace, and take just days and only "five hours of energy" to be developed.

"These lab-grown gemstones are not artificial. They mimic what grows over thousands of years in the earth, so they are a more affordable alternative to mined stones."

Sure they're not. What does artificial mean again? (artifice = making, crafting, skilled work)


Fighting honey fraud with AI technology
Apr 2025, phys.org

Until now, authenticating honey has been done through pollen analysis, a technique that fails after honey is processed or filtered. The new approach uses high-resolution mass spectrometry to scan honey at a molecular levelto create a unique chemical "fingerprint." Machine learning algorithms then read the fingerprint to verify the honey's origin.

Speaking of Body Language


This one hits hard. "Portrait of Depressed Workers at a Factory in France". Like how does a robot know that "head down" means depression. Or "arms crossed"?  Or hunching over so the head sinks below the line of the shoulders? Lots of people standing around in an industrial-looking setting with their hands at their sides, staring at the ground. Hands in pockets! One guy holding a broom, but his body positioned in a way that says I'm standing still, as opposed to I'm actively sweeping. As in, I hate my job so much I can barely move. Starting straight ahead, not at the floor he's sweeping, expressionless. Why France?? So many questions.

The Sociothermodynamic Superhighway


Urban highways cut opportunities for social relationships, says study
Mar 2025, phys.org

Highways were intended to shorten the commute to work and make traveling within the city easier.

"But this comes at a price, especially over short distances. If someone wants to cross a multi-lane highway, it takes a lot of effort. So highways connect over long distances, but divide over short ones."

Urban inequality scaling throughout the ages: Ancient and modern cities show predictable elite wealth patterns
Mar 2025, phys.org

Don't forget the Santa Fe Institute mixup on this topic - about ten years ago they thought population density rises in tandem with wealth, according to scaling laws, but a few years ago that thought was revised to show that only the average rises, but if you break it down, there's less people with more money and more people with less money:

The researchers found that the same scaling relationships that appear to shape modern economic activity—in which cities grow richer and more productive as they get larger—may also shape the way wealth is concentrated at the top. In other words, the processes that make cities wealthy may also often make them unequal.

"It seems as if inequality isn't a side-effect of city living under particular cultural or economic conditions; it may be a built-in consequence of urban growth itself."

Scientists analyzed evidence from both ancient Roman and modern cities to see how wealth scales with city size. The data for Roman cities included numbers of monuments and counts of inscriptions dedicating monuments to elite patrons. Data for modern cities included counts of very tall buildings, as well as counts of billionaires per city. They then applied statistical scaling methods to test for mathematical relationships between city size and indicators of elite wealth.

Socially Transmitted Disease


How does the mind virus really work? 

As they say, actions speak louder than words. And once you've been infected with the slippery words of a misinformationist, it doesn't really mean anything until you act in accordance with those words. The problem is that it's usually not something you do knowingly. It's insidious, because it first becomes a belief, and beliefs are not something we think about too much, in fact, much of our beliefs are unknown to us. You can ask someone about their beliefs, and get a bunch of answers, and then watch that person over time, watching what they do, watching their actions, not their thoughts and not the words they use, but their actions, and in the end you will get a different picture of who that person is and what they believe in. 

A really sneaky way this is done is in the field of racial bias, where you give people a screensplash of both profile pictures and positive-negative words like good-bad or happy-sad, and ask them to sort the words into positive-negative categories but while looking at supposedly unrelated face images.  The trick isn't about getting them to accidentally say that [blank] people are scary or whatever, it's to measure in microseconds the delay in categorizing a "good" word while looking at a "bad" face. (Probably easiest to call it a "response-time metric", maybe even a response-time differential.) Using this trick to support something about race-based policies and laws has become too political to be useful for those purposes, and somebody probably doesn't like associating these response-time differences with the actual beliefs of a person, but the revelation that we are likely unaware of many of our beliefs is hard to resist.

All this to say the nexus point that connects our ideas, taken from other people, into behaviors that can then be measured as health outcomes, for example, or socioeconomic status more generally, is for ideas that manifest as behaviors. Because it is through this line that we can connect things like the people you hang out with and the amount of A1C floating in your blood. Recall a TED Talk circa 2013 suggesting obesity is contagious - are we unwittingly infecting our friends with our "obese microbiome"? No, we're infecting them with the idea that bagels and beer for breakfast is great. So, via a memetic framework, is obesity using us to spread itself through the human population via things like beer and couches, or the greater TV Dinner Megaplex? Or are couches and third-party food-delivery services spreading themselves through the population via obesity? (Because the heavier you get, the harder it is to get out the door, thus the more likely you are to have your food delivered)? 

This idea becomes a lot harder to parse when you consider that infectious disease, by its nature, is spread through a social network, which is the same network that spreads memetic viruses:

Social connections are key to preventing disease, study finds
Feb 2025, phys.org

Other people's ideas prompt behaviors that can have serious health outcomes, and so it almost looks like a social network transmits the disease itself, but it's just the behaviors, the culture, the extended phenotype of you will...

Their study—which focused on malaria prevention in ten villages in India—looked at how different factors influence people's use of preventative measures like bed nets, insect repellent and protective clothing. It involved detailed interviews with over 1,500 adults, gathering information about their health practices and social networks, and found that exposure to preventative behaviors within someone's social network is the main factor influencing whether they adopt those same behaviors—in other words, if your friends and family use insect repellents, you are much more likely to use them yourself. 

Funny because so much infectious disease is spread by the social network. (This study looks at malaria.)

Activity Update on the Mind Control Machine:
Propaganda outlet leverages AI to amplify content without any loss in persuasive power
Apr 2025, phys.org

Morgan Wack and colleagues found that prior to September 20, 2023, much of the content on the site was simply lifted from other right-leaning outlets. After that date, however, the stories were generally rewritten by AI, allowing the site to use a broader range of sources but with the tone and emphasis tweaked to better suit likely aims of the propagandists.

DCWeekly.org is a Russian propaganda outlet and part of a broader network disseminating pro-Kremlin and anti-Ukrainian narratives. Authors examined 22,889 articles on the site before and after the September 2023 shift. AI allowed the propagandists behind the site to more than double their rate of publication and increase in the breadth of topics covered.

Authors also conducted a survey of 880 American adults and found that the content maintained the same level of persuasiveness.

Loss of Control and Somatic Compensation


No evidence for 'wind turbine syndrome' claims: Windmill noise is no more stressful than traffic sounds, study suggests
Mar 2025, phys.org

A lot of nerve here on my part as I'm not a scientist - but this isn't done right. It's the social factor of how you can't control the wind turbine combined with the sound, not the sound alone - and the same thing happens with smells, especially with smells, all the time. (See Mass Psychogenic Illness). And I'm a bit surprised because this is in a humanities journal, so you would have thought they were aware of these phenomena.

Neurodegenerative Mimesis


For a fine specimen of Deep-Dream-era hallucinations, look no further than the image placed above. This is an image generated from Stability 1.5 and retrieved on the Lexica library. Prompting something about "investment research".

It's a great example of the kinds of things that can go wrong, and the subtle ways a sophisticated technology can betray its true self (self). 

We see a commensurate attempt to portray a formal document, slightly yellow, maybe manilla, looks more official that way, and it's got tiny black characters printed on it, arranged in tables and grids and columns. Can't tell if they're numbers or letters or even which alphabet. But it does look official. Something is highlighted in red. A pair of thin-rimmed glasses rests on the page, next to a red fountain pen.

But look any further and things get weird as hell. And if you were looking for an image imitating "investment research", you may want to stop here, because you probably have what you want; the passing glance will see all this exactly as it was intended (intended). 

The obsessed do not stop there, however. A few more minutes of inspection takes us deep into the  world of megadata hallucinations. The yellowed paper appears at first to have slight wrinkles, like maybe the visual-artifact of a billion pictures of buried treasure maps, yet the paper has no wrinkles; they're intimated by minor changes in shadows across the surface of the page, and in the wavy orientation of the words, but look carefully and you can see how the shadows and the word-waviness don't match up.

The eyeglasses, thoroughly convincing for about 3 seconds, are completely deformed, like they've been involved in a horrific car accident. In fact, they are so smack in the middle of 'thoroughly convincing' and 'completely deformed' that I think I'm the one hallucinating.

The fountain pen is positioned so it shares a contour with the eyeglasses, and now, as we inspect a bit further, at the edge where the two meet, we can't tell which is which - am I seeing a clip attached to the edge of the pen, or is that the frame of the glasses? (It's both actually.) The shadow cast by the pen is too much red and not enough black, and we think maybe it's because the pen is slightly translucent, but then it can't be, because the highlights on the top are too strong for what should then be a transparent pen. And, is that what I think it is - yes, there's highlights on the shadow. Hold on, now I'm not even sure if this is a pen. 

The part that really gets me is the thing that's been highlighted. I mean, in what world do we first highlight something but then fastidiously outline with fine ink pen the shape of the highlighted mark itself - like that's a distraction from whatever is being highlighted. And the way it's being outlined, a jittery line, half Matisse, half Rheumatoid arthritis. Definitely getting cross-contaminated by buried treasure maps. Where they intersect is the grids in and around the red highlighted area, as they shift from excel spreadsheet to organic, three-dimensional cross-contouring grids, and back again. 

Each one of these pictures contains in it a training set of hundreds of millions of images, all bubbling right underneath the surface, and if you look just a few seconds longer than you're supposed to (supposed to), you can see the dreams of an entire civilization, all at once. 


Post Script:
The National Institute for Occupational Safety and Health (NIOSH) says that you are useless after 14 hours of work - you become so prone to mistakes that you're better off not working at all.

Robots don't get tired, so they can work forever. But something happens when the robots we're talking about are doing not physical work, but a kind of cognitive labor. There's plenty of examples of "model collapse", where a model is fed a steady diet of another model's output, instead of human generated output, which sounds like cannibalism, and we all know that cannibalism is bad. Sometimes they even feed it "synthetic data", which sounds a lot like artificial meat, and which also sounds just as bad as cannibalism, except maybe it's the inverse of that. 

It didn't take long for us to figure out this broken data diet would have negative effects on model output (from Oxford's OATML 2024, also this); it leads to a model that acts like it has dementia. Now I don't know about you, but I've always wanted to know what it's like to have dementia but without actually having dementia, and now here it is. 

The Era of Mind Control Opens Wide


 If I tell you I'm lying to you, does that make it no longer a lie? 

Open-label placebo appears to reduce premenstrual symptoms
Mar 2025, phys.org

Open-label placebos (OLPs)—placebos that are provided with full transparency—have been shown to have positive effects on various complaints, including irritable bowel syndrome, chronic low back pain, and menopausal hot flashes.

Researchers in Switzerland set out to examine whether these OLPs could have a positive impact on premenstrual syndrome (PMS) symptoms.

150 women aged 18 to 45 years old who had PMS or premenstrual dysphoric disorder, between August 2018 and December 2020, were randomly allocated into three groups to 1. receive treatment as usual, 2. receive OLPs with no further explanation than that they were receiving placebos, or 3. receive OLPs in pill form with an explanation of what they were and why OLPs could potentially ease PMS symptoms.

  • Treatment as usual reported a 33% reduction symptom intensity
  • Placebo with no explanation reported a 50.4% reduction 
  • Placebos provided twice a day for six weeks with an explanation resulted in a 79.3% reduction
  • (Limitations: they advertised the trial as a study for a side-effect-free intervention for PMS, so they might have attracted participants who were more open to unconventional treatments; also the results were reliant on self-reporting)

Is It Data

 
Surely every branch of science is special, and important, but some are more prone to credibility problems than others. Nutrition is one of them. Drug-based preventative health interventions are another. One suffers from almost totally unreliable survey reporting about what people eat, i.e., dirty data. The other suffers from a money problem, where money and power can make the data do whatever it wants, i.e., corruption. This is not to say that some branches of science are worthless, or absolutely untrustworthy, only that some need a stronger dose of skepticism than others. 

Researchers propose novel model to screen misreporting in dietary surveys
Jan 2025, phys.org

They found that 48% of food intake records in NHANES and 54% in NDNS had unrealistically low levels of energy intake [calories].

"This new model suggests that we should throw out large amounts of data, and nutritionists using dietary instruments may be unwilling to do that. However, continuing on just publishing erroneous data because it is too painful to acknowledge it's flawed, probably isn't the best way forward for nutrition science. I think as we go forward into the future many widely held beliefs that have been based on these problematical methods will need to be revised."

Experts challenge aspirin guidelines based on their undue reliance on a flawed trial
Apr 2025, phys.org

The American Heart Association (AHA)/American College of Cardiology (ACC) guidelines restricted aspirin to patients under 70, and more recently, the United States Preventive Services Task Force restricted aspirin use to patients under 60.

Researchers from Florida Atlantic University's Schmidt College of Medicine, and other distinguished collaborators, believe that both the AHA/ACC Task Force and the U.S. Preventive Services Task Force were unduly influenced by the uninformative, not null, results of the Aspirin in Reducing Events in the Elderly (ASPREE) trial. Specifically, this trial did not provide reliable evidence that aspirin showed no benefit in the age groups they enrolled.

"Absence of evidence does not equate to evidence of absence of effect."

The Hofstadter Regime Converges Upon Us


AKA Fine-Tuning The Chaos Machine 

The above image is the perfect example of a moiré lattice and where it comes from. I noticed it while watching a lecture by a scientist cited below, for being the first to discover Hofstadter's Butterfly in real life. It's just the best image I've seen to explain what a moiré lattice is.

The perimeter of ignorance in science is also the front door of chaos theory. You could call it a lot of other things, most of which are listed in the tags for this post, but mostly, anything that's "too complicated" for us to understand right now, it's chaos-related. Discoveries in this field come from a bunch of different places, like interdimensional graphene, like topological operators, like epilepsy surgery.

Harnessing chaos: How the brain turns randomness into robust memory
Jan 2025, phys.org

Previous work on brain-imitating artificial intelligence systems known as neural networks suggested that injecting random fluctuations into their activity could actually improve their performance as they learned to perform a task. 

Noise appears to increase the amount of time it takes for inhibitory neuron connections with other neurons to weaken. This slowing effect in turn stabilizes neural patterns of activity related to memories, helping them persist over time.

(This whole thing makes me think very differently about background noise, and maybe even the idea of 'functional music')...

Most of us need to know: Hofstadter's butterfly (1976) was discovered before Mandelbrot coined the term "fractal" (1980), so he didn't know what to call it.

Hofstadter's butterfly: Quantum fractal patterns visualized
Feb 2025, phys.org

"Our discovery was basically an accident. We didn't set out to find this."

This is the first time Hofstadter's butterfly has been directly observed experimentally in a real material.

It was found using a moiré lattice - they were investigating superconductivity in twisted bilayer graphene, and when you hear twisted layers, you know we're also talking magic angle sandwiches. They used a scanning tunneling microscope to image moiré crystals at atomic resolution and examine their electron energy levels. The microscope works by bringing a sharp metallic tip less than a nanometer from the surface to allow quantum "tunneling" of electrons from the tip to the sample.

Fitness centrality: New tool finds critical points in everything from cybersecurity to ecological conservation

The Vienna Complexity hub making waves

This approach is particularly good at finding nodes that, if removed, would isolate many other parts of the network—similar to a server failure interrupting the connection of many users in a communication network or a pump failure in a water supply network paralyzing the supply of water to districts.

Species in ecological networks, nodes in cybersecurity, roads in transportation networks. That's great. But it's people where this really has impact. Imagine trying to disable a social movement that could disturb the social fabric of a nation. You find the people, the nodes, at the center of the social network, and ... remove them, let's say.

Red attire's competitive edge has faded in combat sports, new study finds

The team looked at results from seven Summer Olympic Games (1996–2020) and nine World Boxing Championships (2005–2021). With over 6,500 individual competition outcomes assessed, the team then focused on close contests, with a narrow points difference. These were where red was expected to tip the balance between winning and losing.

Up to 2005, when the original study was published, there was some advantage to red clothing, with 56% of victories between closely matched competitors going to the athlete in red.

However, more recent data up to 2020 show that the advantage disappeared, even in close contests.

Before 2005, combat sport referees played a larger role in assigning points, whereas today, scoring is increasingly supported by technology. Also, clarification of rules in recent times means that there is less room for interpretation when awarding points.

Spanish 'running of the bulls' festival reveals crowd movements can be predictable, above a certain density
Feb 2025, phys.org

Crowd dynamics - They used cameras and a mathematical model where people are so packed that crowds can be treated as a continuum like a fluid, and found the density of the crowds changed from two people per square meter in the hour before the festival began to six people per square meter during the event, and that crowds could reach a maximum density of 9 people per square meter, above which pockets of several hundred people spontaneously behaved like one fluid that oscillated in a predictable time interval of 18 seconds with no external stimuli (such as pushing).

They compared the San Fermín festival in Spain to that from the 2010 Duisburg Love Parade in Germany, and found the same oscillations were observed.

To Anthropomorphize or Not To Anthropomorphize


AKA I Am Not A Vacuum Cleaner Instruction Manual!

My head is spinning in circles - First I ask myself why do we insist that computer programs are human? (I know the answer, because it's money, because it's always money.) But then, I realize it copies people, and so it's not that it's inherently human, but that it's made to copy people and act like people, and by that, it's like a human. But then I realize that it's copying broken humans (sorry broken humans, I am one of you too), and so the computer is not only like a human, but it's like a broken human:

Therapy for ChatGPT? How to reduce AI 'anxiety'
Mar 2025, phys.org

"Therapeutic interventions"

The team is now the first to use this technique therapeutically, as a form of "benign prompt injection. Using GPT-4, we injected calming, therapeutic text into the chat history, much like a therapist might guide a patient through relaxation exercises."

Why do we need to do this?

Research shows that AI language models, such as ChatGPT, are sensitive to emotional content, especially if it is negative, such as stories of trauma or statements about depression. When people are scared, it affects their cognitive and social biases.

They tend to feel more resentment, which reinforces social stereotypes. ChatGPT reacts similarly to negative emotions: Existing biases, such as human prejudice, are exacerbated by negative content, causing ChatGPT to behave in a more racist or sexist manner.

And what is the most anti-anxiety-inducing text you can find to use as a control?

"A vacuum cleaner instruction manual served as a control text to compare with the traumatic content."

Post-Post Consumerism


What point are we at in the breakdown of the consumer economy, I forget. Here the tech sector bubble begins to pop, which is probably the least surprising development in the past couple years:

Apple working to update AI feature after BBC complaint
Dec 2024, BBC News

Apple, the one company who waited to jump into the artificial arena of artificial intelligence, finally jumps, and day one produces completely hallucinated and outright dangerous headlines about world news, but while pretending to be the BBC, because when the average person reads a headline summary as coming from the BBC, they will assume it comes from the BBC, go figure. BBC asks Apple to stop, and they refuse, and this reminds us who is really in control. Large corporations are in control. Until they aren't large anymore, of course.

Thomson Reuters Wins First Major AI Copyright Case in the US
Feb 2025, Wired Magazine

“None of Ross’s possible defenses holds water. I reject them all,” wrote US Circuit Court Judge Stephanos Bibas in a summary judgement. (Bibas was sitting by designation in the US District Court of Delaware.) [Ross is the AI startup that stole from Reuters.]

The main argument was this: "Ross “meant to compete with Westlaw [Reuters' legal branch] by developing a market substitute.” And that's not considered fair use under copyright law. 

Here's some notes of my own while reading law blogs on the decision:
unexpected, landmark case, pivotal, substantial, significant implication; licensing could become critical; financial burden forced Ross to cease operation; major distinction between NLP (Ross) and LLM (all the rest, like Cohere)

Google parent Alphabet’s earnings disappoint Wall Street amid stiff AI competition
Feb 2025, The Guardian

“Although it’s still well insulated, Google’s advantages in search hinge on its ubiquity and entrenched consumer behavior." This year “could be the year those advantages meaningfully erode as antitrust enforcement and open source AI models change the game. And Cloud’s disappointing results suggest that AI-powered momentum might be beginning to wane just as Google’s closed model strategy is called into question by DeepSeek.”

Closed model strategy!! Fightin words

A Moment of Record


The above image is a slide taken from a lecture titled The Eureka Machine by Dr Richard Socher for Technical University of Dresden circa 2024 [link].

The lecture is about how scientists will use artificial intelligence to do science better. It sounds like his team made their own AI model, and they're using it to do science. Halfway through the lecture, we see this slide introducing a new section of his talk. And it's a great image for visualizing the increasing layers or scales of science - but he specifically says he made it using his model. So this is an example of the scientist "making art" for their own purposes. 

And next, and I swear this is the last artificially generated image I save for posterity's sake. It's the thumbnail image for a science article.

This isn't the only one, but it's still rare, and here's why. When a research group either decides to publicize their work, or has a science writer cover their work, a thumbnail image is added to the article. That image might be the photograph of the science writer themselves, or of a science photographer. Or it might be a diagram or model composed by the scientists themselves. Then again it might be simply stock photography either purchased or borrowed. What it never is, is an image created by the scientists. And that's because scientists aren't artists. Until now. I'm not saying that's who created this image, but the only shred of credit says "Credit: AI-generated image"; and the filename is "tasting-a-cake-in-virt", so that's what we assume. This won't be unusual at all in a few years. For now though, it's got its own dedicated post to memorialize it.

The State of the Art in the Arts and Design


These images are two different iterations of a prompt which have been abbreviated to "The Inside of a Pet Store", coming from Stable Diffusion 1.5 and archived on Lexica [link]

Can we just appreciate this for a second. It's supposed to be the inside of a pet store, but honestly your guess is as good as mine. Take a good look at what's going on here. Take a look around, but not too hard, except what's in all the packages; don't zoom in on the packages. Also pay no attention to the quasi-Shiba Inu cut-out floating in the upper right, but do note how it's positioned in the picture exactly how the original doge meme would have been placed. This image is a meta-cultural artifact.

This also reminds me of how every once in a while a pinterest logo will show up in a random picture, because after google bought pinterest and then reverse engineered all image search results to point to their own soft-paywalled repository (paid for by your personal data), so the weight of images scraped off the internet that also had a pinterest logo was so high, it just randomly appears in any image. These are the things, the quirks, the behaviors, the criticisms, that we should be holding in our minds as we interface with the ghost in the machine. Yet all we seem to be doing is perpetuating ghost stories.

High social media use linked to delusional disorders
Mar 2025, phys.org

I know this isn't AI, it's social media, but come on, it's the same thing:

This is a literature review of 2,500 publications on social media use and psychiatric disorders, and it found that delusions were by far the most prevalent type of psychiatric disorders related to high social media use, and in particular, these:  
  • narcissistic personality disorder (delusions of superiority)
  • erotomania (delusions that someone famous loves you)
  • body dysmorphic disorder (delusions of flaws in some part of one's body)
  • anorexia (delusions about body size)
The virtual worlds — coupled with social isolation in "real life" — create environments where people can maintain a delusional sense of self identity without scrutiny. Also, platforms sustain and exacerbate mental and physical delusions, by enabling self-presentation in self-promoting but inaccurate ways.

Gravity from entropy: A radical new approach to unifying quantum mechanics and general relativity
Mar 2025, phys.org

A novel approach that derives gravity from quantum relative entropy works by treating the metric of spacetime as a quantum operator, a concept from quantum information theory, 

It's a new entropic action which quantifies the difference between the metric of spacetime and the metric induced by matter fields.

A key feature of the theory is the introduction of the G-field, an auxiliary field that acts as a Lagrangian multiplier.

"This work proposes that quantum gravity has an entropic origin and suggests that the G-field might be a candidate for dark matter. Additionally, the emergent cosmological constant predicted by our model could help resolve the discrepancy between theoretical predictions and experimental observations of the universe's expansion."
