Structural Decoherence and Assembloid Resistance

Things to consider as we dematerialize into our furniture - Buildings as living organisms and we will all be living in crystals in the future. Otherwise, how did it take us this long to figure out we could do this with 3D printing:

'Implosion carving' shrinks 3D photonic devices 2,000-fold for visible-light computing

They figured out how to create vacancies at any site across a material and then shrink it to about 1/2,000 of its original volume, making nanostructures with feature sizes with a resolution less than 100 nanometers; because that resolution is smaller than the wavelength of light, the devices can bend light in specific ways that allow them to perform optical computations.

Novel origami pattern turns flat sheets into load-bearing 3D technology

May 2026, phys.org

https://techxplore.com/news/2026-05-origami-pattern-flat-sheets-3d.html

It's a "doubly curved lens box", also called a flat tendon-driven origami metamaterial with stiffness reprogrammability. ... Starting from a desired curved shape (such as a sphere, torus or vase-like surface), the researchers used differential geometry—mathematical theories for origami tiling and developable surfaces—followed by numerical optimization to compute the exact crease pattern needed so that, once folded and locked, the origami shell would match the target geometry. ... They next laser-cut and folded paperboard sheets into these patterns, assembled them into shells, and embedded thin cables ("tendons") through specific points. "By tightening or loosening the tendons, we measured how the stiffness changed and showed that the shells could go from saggy and flexible to rigid and resistant to twisting and bending."

A low-tech solution to the 6G problem—metacrystal panels offer cheap way to guide wireless signals around corners

Jun 2026, phys.org

https://techxplore.com/news/2026-06-tech-solution-6g-problem-metacrystal.html

Higher-frequency channels of 6G communications are more easily blocked by walls, people and other obstacles. Metacrystals are passive, 3D-printed smart panels that can shape wireless signals without electronics, a power supply or active tuning.

Unlike many existing intelligent surfaces, which often perform only one task for one signal direction, the panels can handle several incoming waves at the same time, operate over different frequency bands simultaneously, work in reflection or transmission mode, and even fully absorb unwanted signals.

Rising heat and humidity challenge energy-efficient data center cooling worldwide

Jun 2026, phys.org

https://phys.org/news/2026-06-humidity-energy-efficient-center-cooling.html

They assessed historical and projected temperatures and humidity levels around the world and compared them with the conditions required for "direct air free cooling," wherein naturally cold outside air is brought in to cool a building or equipment.

"We found that periods of time when temperature and humidity exceed recommended operating thresholds for direct air-free cooling are becoming more frequent and lasting longer in many regions"

One of their key findings is that the largest changes are not always seen in average conditions. In several regions, worst-day conditions are intensifying more rapidly than average conditions, indicating that environmental stress is becoming increasingly concentrated in rare but consequential events.

Funny way of describing the climate catastrophe: "Worst-day conditions are intensifying more rapidly than average conditions"

Duped - Truth Default Theory and the Social Science of Lying and Deception

Written by Timothy R. Levine on University of Alabama Press, 2020

Hardcore academic, but not the kind who makes words up to confuse you instead of just doing a better job of explaining things. He never believes his own results; instead he changes the variables and does another study. He's the opposite of the self-stimulating hermit who writes not to communicate to others but to hear himself talk. He's a real model of what a researcher should be. He's got healthy but persistent suspicion of everything, he's really intent on setting the record straight, on being absolutely certain before you say something, and he's not discrediting or disparaging anyone else in the process. And finally, in a way you never see in a science book like this, it does come with a climax at the end, and makes it feel like the whole thing was a story, constructed on purpose, with a beginning, middle, and end. You wish every researcher was like this. He even mentions how he gets upset that taxpayer funds go to wack theories. 

Also, the amount of time he spends and the effort in making it crystal clear who was the brains behind the "veracity effect" at the beginning of Chapter 12 is not only reaffirming to hear such respect but also another opportunity to see into the academic machine in ways that are often ignored. Sometimes I wonder if it's out of a kind of elitism where authors think "regular readers" wouldn't understand or don't care about these details. Not true, and I feel more respected as a reader. 

• Most people are honest most of the time.
• Most lies are told by a few prolific liars. 
• (Taken from Turner) Honesty as complete disclosure may be inaccurate, and may be better described as fidelity to maintaining a relationship by selectively controlling information.
• (Levine) Deception may not be a moral choice, but a practical one, and need not be conscious, but does serve a purpose. 
• The younger you are, the more you lie. 
• In deception studies, your chances of guessing correctly whether someone's lying is 54%.
• Most people, when they do lie, are pretty good liars. 
• People who appear confident, friendly, composed, and engaged tend to be believed.
• Some people have honest demeanors and some don't, and that's it. 
• Liars do the same "telltale" behaviors as non-liars, leading to much misclassification. 
• Non-verbal cues for deception detection came from folk wisdom, but also the coincidence that many of the researchers came from non-verbal communication studies.
• Most people think lack of eye contact is the #1 sign of deception, but also shifting posture, response latency, fast talking, speech errors, more pauses and hesitation, less plausible content, contradict themselves, less conversationally involved, uncertainty in voice, less friendly and cooperative, and more nervous.
• High pitch and pupil dilation correlate, but it's small. 
• Theories that don't work: Ekman's leakage theory that we unconsciously "leak" the truth via gestures etc. while lying , but only for emotionally potent, high stakes lies. He sums up all the other theories of deception in a meta-theory called Cue Theory: deception is a psychological state that manifests behavioral cues which can be detected. He also references a man named Kraut 1980s who says all deception theory is biased on the assumption that observable behavior represents internal states.  
• He has concerns about deception research in the legal and criminal psychology areas - they seem cliquish and provincial; they co-author and review one another's work. 

• "Deception becomes probable when the truth makes honest communication difficult or inefficient."
• "Deception - or more precisely, the possession of problematic information ..."
• Deception becomes probable when people judge truthful information as so problematic it can't be disclosed (McCornack).
• Deception is purposive, i.e., people lie for a reason: "The basic functions of communication include being informative and sharing information and influencing the affect, cognition and behaviors of others; entertainment; and building, maintaining or ending social, personal, and professional relationships." p154

Deception Motives:

• Personal Transgression - cover up a misdeed
• Economic Advantage - money as always
• Personal Advantage - promotion at work, avoid a disliked task
• Social or Politeness - saying a stupid gift is really nice
• Altruism - to protect another; father lying to daughter about being sick
• Self-Impression Management - status? (cant this be #3?)
• Malicious - cause harm to others
• Humor - like a prank
• Pathological - delusional, disregard for consequences
• Avoidance - sorry can't make it tonight, my fish tank just exploded

Variable Affecting Truth Bias:

• Experimentally primed suspicion - when you are told to be suspicious
• Closeness of relationship - closer you are, the more you're biased to believing them
• Face-to-face interaction 
• Mere questioning aka The Probing Effect - watching a person be questioned, no matter how they answer, makes them look more honest to you (now that's an interesting one)
• Sender demeanor believability - this is the strongest variable

Truth Default Deactivation Triggers:

• Projected motive for deception - you think they have a reason to lie
• Dishonest demeanor - they "look like" they're lying
• Incoherent message content - doesn't make sense
• Lack of correspondence between content and reality - also doesn't make sense
• Warning from a third party

On Scientific Revolutions and Paradigm Shifting:

This only applies to deception research, but it's the common phenomenon you see all the time preceding a drastic shift in thinking within a field of study. For decades, you had a 56% chance of detecting deception, based on the deception research. But those experiments were just not generalizable, or in other words, they were too "artificial" to be compared to real life. It's an example of how easily we are hypnotized by our own time. 

The Behavior Quotient aka The Demeanor Index:

Alas, this is the reason I bought the book; people appear so apt to believe me when I talk, and I find that so weird because I would be super-suspicious of myself if I heard myself talking, and I wonder what it is that makes people like this. He says this list is worth "vastly more than what you paid for this book." It started because in one of his experiments there were a few "senders" who everyone got wrong, and a few who everyone got right, so they looked at those people, and this is what they found:

Sincere (Honest) Demeanor Cues:

• Confidence and composure
• Pleasant and friendly interaction style
• Engaged and involved interaction style
• Gives plausible explanations

Insincere (Dishonest) Demeanor Cues:

• Avoids eye contact
• Appears hesitant and slow in providing answers
• Vocal uncertainty (in tone of voice)
• Excessive fidgeting 
• Appears tense, nervous, anxious
• Portrays an inconsistent demeanor over course of interaction
• Verbal uncertainty (bad vocabulary?)
• I call all these things basic public speaking skills?

Finally, and providing climax in a science book, something which never happens, or which isn't necessarily supposed to happen, they reveal that in fact it's possible to break the 56% accuracy ceiling. Expertise is possible but it's context-dependent and involves knowing how to prompt diagnostically useful information rather than passive observation of behavioral cues. The experts scored 100%, not 56%.

Note that up until now, deception researchers used scripted questions, which undercuts the experts' expertise; the whole point of them being experts is them knowing which questions to ask. 

How did they do it? Start conversationally, get to know the person. Then, ask critical information about th eissue, like facts that can be corroborated. Then ask about their integrity and views on cheating (the experiment was a simulated cheating scenario). Then they circle back and ask the same questions again ina  different way, but remembering the first answers. They also tried to convince them to confess, stressing the importance of honesty. 

Five Keys to Improving Lie Detection:

• Correspondence of communication in evidence - what you said vs known facts
• Content in context - situational familiarity, knowing whether this is a joke or has double meaning
• Assessment of deception motives
• Diagnostic questioning
• Persuading honesty

Determined - A Science of Life Without Free Will

Written by Robert Sapolsky 2023

I've read too much of his work by now, not to mention sitting through all 72 hours of his Human Behavior 101 course at Stanford. So much so that I'm not the audience for this book because I already 1. Believe him, and 2. I know why I believe it. That being said, there are entire chapters in here about physics and randomness, and I am not a happy camper when I see a scientist of one discipline write about a different discipline. It's one thing if it comes up in conversation, but to use your platform, which you've earned by being an expert in your field, to talk about stuff beyond that field, not cool. I call it the Neil DeGrasse Tyson effect, because during the pandemic, when he was really at the peak of his public persona, he talked a lot about biology and epidemiology and even air quality on the platforms he had access to (television shows, podcasts, etc.) because of his recognition as a **physicist**. And an astrophysicist at that, which is about as far as physics gets from things biological. That pissed me off. Personally, because I was an industrial hygienist at the time, and if there's one thing that's "in the lane" of the IH, it's infectious aerosols and indoor air quality. But I was moreso pissed because it's deception, or at least an exploitation. I know it's tempting, when you're smart, and trusted as an authority, to answer basically any question that comes your way; you might even feel obligated. But it's not professional. And I get that Sapolsky needed a chapter on randomness to talk about free will, but I didn't buy this book to hear him talk about physics. For that I buy a book by a renowned physicist (just not Leonard Mlodinow, because his 2008 book The Drunkard's Walk sucked and was a total disappointment). The whole thing has an air of ... mental incest? Self-stimulation I guess is what you might call it if your were trying to be professional; there's a couple other phrases that come to mind, but they sound a bit adolescent so I'll avoid it.

Next, I swear he's got as much text in the footnotes as he does in the book proper. That's annoying, and makes it look like you didn't put enough thought into the book. Also makes me wonder how his editor and publisher let him get away with it.

Alas. All that being said, the way he introduces the book and his ideas is so good and so effortless, so amicable. This is a guy who knows how not to pick fights - he spent much of his life hanging out with baboons (and never once got eaten to death!).

• Right off the bat, he says explicitly he's not trying to pick fights, and not arguing on a personal level with anyone. A good way for any writer to start their book of arguments. 
• And the very next section is titled "Whom I Will Be Disagreeing With". The way he pre-emptively addresses his critics is so instructive, and likely the result of having written several books already, and experiencing the resulting maelstrom of highly informed, sometimes highly combative opinions. 

• "While we are free to do as we intend, we are not free to intend what we intend." p19
• Alien hand syndrome, and anarchic hand syndrome (Dr Strangelove and the unwanted Nazi salute)
• "Chronotheology" is what critics called Libet's experiments that seem to show that some part of your brain makes decisions before you're even aware of it. 
• "Turtleism" is "turtles all the way down" (and is strongly correlated with the "Always Has Been" astronaut shooting the other astronaut meme).
• I find these too hard to believe, but I will write them down: Lying by voicemail increased request for mouthwash, and lying by email for hand sanitizer. See The MacBeth Effect: C Zhang and K Lijenquist 2006; SW Lee and N Schwarz 2010; E Kalanthroff, C Aslan and R Dar 2017; Schnall, Benton, Harvey 2008; Kaspar, Krapp, Konig 2015
• After pointing out the human frontal cortex takes 12 more years after the rest of the primates to develop, "the genetic program of the human brain evolved to free the frontal cortex from genes as much as possible" (what I'd rather call cultural evolution and the arena of artificial selection)
• Rainforest vs Desert dwellers and why "55% of humans proclaim religions invented by Middle Eastern monotheistic shepherds". (Rainforest dwellers tend to have polytheistic religions.)
• The Hungry Judge (not easy to get to the bottom of this because for example the wikipedia page as of 2025 said it was disproven, but when you consider just the biases and motives of potential actors, you might want to err on the side of it being true?) This is in a footnote, not the text proper - "The finding was challenged by some critics who suggested that it was a statistical artifact of the way parole hearings were carried out; the authors reanalyzed their data to control for these possibilities, convincingly showing that the effect was still there. An additional study showed the identical pattern: subjects read job applicant profiles from out-group minority members; the longer it had been since a meal, the less time was spent on each application." p107
• On the "Initial Conditions" of the Butterfly Effect (inside joke) - he says that when Lorenz came up with his strange attractor theory, he tried to summarize it with a metaphor about seagulls, but a friend suggested something more picturesque, and by 1972 we have the title of the talk ... p133 ("What Could Be Worse Than the Butterfly Effect?" R Bishop in Canadian Journal of Philosophy 2008)
• *** Some things were free will and now they're not, because we learned more. "In this view, "free will" is what we call the biology that we don't understand on a predictive level yet, and when we do understand it, it stops being free will." p150
• When lethal injection machines were invented, some states stipulated that there'd be two separate delivery routes, each with a syringe full of poison, two people would press each of two buttons, and a randomizer in the machine would infuse the poison from one syringe into the person and dump the contents of the other into a bucket. ... defusing the sense of responsibility. p152
• [This is where I stop reading entire chapters about physics by neurologists.]
• "On the Reception and Detection of Pseudo-Scientific Bullshit" by Gordon Pennycock and wisdomofchopra.com
• ***Dan Dennett's Nefarious Neurosurgeon - a surgeon does a procedure on a patient and then lies and says she implanted a chip in their brain that robs them of their free will, and that she now controls them. Unburdened by responsibility for their actions, they become criminal. And that, Dennet says, is how neuroscientists rob people of their free will. p390
• ***In general, it's hard to convince people there's no free will, and hence nobody's actions are their fault, because then also their accomplishments aren't their's either, and they get no credit. Nobody's going for that. Saul Smilansky's Philosophical Illusionism comes to this conclusion. 

• To live through "free will colored glasses"
• In the epilogue he refutes meritocracy arguments - The issue isn't that so-called meritocracies reward un-qualified people, it's how qualified people come to be that way. The opportunities, not the standards, are unequal. p407

The Pencil - A History of Design and Circumstance

Written by Henry Petroski, 1989

It's hard to believe that this is pretty much the only book written on the pencil.

I have a lot of notes; it's all over the place, but that's never stopped me before from posting it all up here.

• The original pencils were made with lead, but they were literally a lump held in the hand; later the lump was put in holders, and later still graphite was discovered (1560's England), although it was called black lead, plumbago, or English antimony at the time, though Germans called it white lead or bismuth, and others still called it Flemish stone, and it didn't get it's name graphite until two hundred years later (1779) when they had good microscopes to see the chemical structure and realize it wasn't lead at all; the word graphite means graph - to write - in Latin, with -ite at the end to denote it's a mineral.
• Thoreau doesn't include pencils on his list of items for going into the Muir Woods.
• The origin of the word pencil is penis, which means tail in Latin; the original use of the word pencil was more like a paint brush. Also, codex is Latin for tree trunk, on which a codex would have been written.
• Early writing used a stylus on wax tablets backed with ivory.
• Much later, guidelines or blind lines as they were called were put on paper in lead, but the words were written in ink 
• Homemade quill pencils circa 1800s America 
• The pencil as we know it today is called the "cedar and graphite" pencil.

• 1560s Borrowdale England - graphite mine is discovered (but called black lead, plumbago, etc.)
• 1675 Nuremburg - Staedtler was making pencils exclusively, and as a joiner (wood cabinet maker), so he was making his own leads
• 1760 Germany? - Faber
• 1790 France? - Conte instigates the revolution in pencil making when a restriction in supply from a war in 1790 made him turn the graphite into powder and add it to "potter's clay and water", which was shaped and fired like clay; Conte had experience making ceramic graphite crucibles for lead cannon balls; today it's called the Conte crayon, but then it was called ceramic lead. Germany never took up this method, and fell behind.
• 1800s American - they're using quill pencils made with a goose quill, a lead bullet, a melting ladle, and a turnip - the quill was cut to length of a couple inches, the end thrust into a turnip and held upright, the bullet melted and poured into the quill ready for use (and the quill was whittled away at increments to reveal the lead?)
• 1810 America - William Munroe a cabinetmaker who makes pencils uses a slurry but not exactly Conte style because it wasn't baked. 
• 1821 Briton New Hampshire - a graphite mine is discovered
• 1830s Concord Mass - Henry David Thoreau's dad John ran one of America's first pencil companies making graphite and clay pencils, but by 1853 they were making more money selling their ground graphite for electrotyping and gave up on pencils.
• 1843 - a Thomas Telford grounds graphite, mixes with water, and pressurized to reform as natural graphite, but it was too expensive.
• 1857 Jersey City Dixon Crucible Co. - Dixon was at it since 1820, but the crucibles made to melt and mold cannonballs for the Mexican America War were of graphite, and Dixon had so much because his dad owned a shipping company that called in Ceylon, where a graphite mine was, and where they straight used the graphite as ballast in the ship, so he set up shop for the War; at this time, some Dixon advertising materials compare their product against fraudulent Germans pretending to make their pencils in America said Dixon used "purely American principles" where "every manipulation is by machinery instead of by hand labor; producing perfection and absolute conformity." (Makes me think of the American food system though.)
• 1851 World's Fair Great Exhibition at the Crystal Palace in London - this changed a lot of things
• 1856 Siberia - AW Faber, who was failing by 1850s due to lack of good graphite, finds a graphite mine in Siberia, and by 1896 a Faber granddaughter marries a Castell and the company becomes Faber-Castell; note that by 1849 Faber was represented in the US, w a factory by 1861, which caught fire, moved to Brooklyn 1872, then to Wilkes-Barre PA 1956.
• 1870 Germany - JS Staedtler's red conte crayon pencil made since 1851 gets popular, but by 1912 Staedtler is sold by a grandson named Kreutzer
• 1873 Ticonderoga New York - Dixon buys the American Graphite Company in Ticonderoga New York, and is making real and good pencils; and continues to do so until 1980 when the buildings are sold to developers; the business remains, headquartered in Florida and w facilities all over.
• 1900s Japan - They have an entire pencil industry by then.

• ***There is a great passage here, "Where Did the Graphite from Borrowdale Go?" AKA "Black Entropy" - The plumbago from Borrowdale had certainly been absorbed into the universe at large over the three centuries since it had been discovered: being blown in dust from all the sawing and rubbing, being deposited on the furniture of pencil factories and on the hands and clothes of their workers, being carried in fabricated veins of lead in millions upon millions of wood-cased pencils made and exported around the world, being buried with the stubs of pencils no one wanted to hold onto, being laid down in notes in the margin of books like trail markers through forests of thought, being redeposited in thin lines of thoughts and images on countless sheets of paper, being twisted and crushed in the lines of crumpled manuscripts and sketches, being burned with the thoughts and images no one wanted, or no one wanted to remember or build. So by the mid-1800s what had once been the world's purest source of plumbago was essentially worked out and had been diffused throughout the world in a three-centuries long fit of black entropy. (p140)

• ***1860s - Erasers are already on pencils, but it was used, and named, by the 1770s, for "rubbing" out black lead (graphite); and by 1900s erasers got so popular that people got paranoid about their marks on paper being erased either accidentally or intentionally, that there were recipes for fixing the graphite, one with skim milk; further: a Dixon catalog early 1900s has a paragraph about erasing in schools, called "The Philosophy of Rubber", about how having an eraser changes the way students think [perhaps a perennial example of our initial interfaces with new technology]. 

• Erasers on pencils were and are not popular in Europe
• Until 1880, European pencils had square lead. 
• There's a war between whittling and rotary sharpeners, and square and round leads; of course we see the rounds win. But people were real into their whittling; the paper wrapped pencil, an alternative to using wood, never took off because people wanted to whittle. 
• 1890 - The yellow pencil is made to match the Austria-Hungary flag, but also in reference to the Orient where the Siberian graphite was coming from; by 1950s America, yellow and pencil go so well together, there's an apocryphal story of a manager distributing half green and half yellow pencils to his thousands of employees, and getting far more complaints about the green pencils ... because we are basically brainwashed at this point, and he, Petroski, poetically calls it psychosomatic (p163)

• Pine was used for the cheapest pencils, then Red Cedar, then Florida Keys Cedar for the finest; wood was chosen for its strength, freedom from warpage, and smooth cutting qualities.
• English closet chest makers in 1700 got red cedar from Virginia and Florida
• Incense red cedar from California works, but it's white not red, so it's dyed, and impregnated with cedar oil for fragrance, and a wax for better handling in production.
• There is also a wood from India that is dyed violet. 

• There's a good illustration on p223 with the author saying the pencil drawings are so wrong they couldn't be produced "by a drunken machinist on a rubber lathe".

• BOPPS - Broken off pencil points
• The diameter of the leads are thinner as they get harder to adjust for breakage at the point.
• A 1600s teacher was whittling goose quills for their students before class.
• People saved their pencil shavings to drive a way moths.
• There's a Sherlock Holmes bit where he used his knowledge of pencils to deduce a suspect. 
• Colored leads have more wax and less clay, and so aren't baked as hard, and break easily; and colored leads, which often were broken in the wooden shaft, tended to leave loose pieces in the machine to revolve with the cutters and prevent another pencil from being sharpened (bane of my existence as an art teacher).
• There was a pencil made from the wood of a preserved tree near a mastadon in a marl bed in Orange County, the pencil's knob made from the mastadon's tooth. 
• Some novelty pencils were made with companion toothpicks or earspoons
• Mechanical pencil names circa 1930s and 40s - Eversharp, Scripto, Autopoint
• The first Russian pencil was the Diamond by Hammer
• By the 1900s the British call pencil leads pencil strips
• There is a standard for pencil manufacturing - R-151-34
• On Dec 8 1941, the Eagle Mikado became the Mirado.
• They spun a drum of paper against a pencil to see how "far" it goes (35 miles)
• There's Blackfoot Indian made pencils, by hand, in 1971
• Pencil workers could reach into a pile and grab exactly 12 pencils, every time, and that's something a machine can't do in one motion.
• Hemmingway "wearing down sever number 2 pencils is a good day's work"
• Pencils are general word processors, Byte magazine
• "The very commonness of the pencil, the characteristic of it that renders it all but invisible, and seemingly valueless, is really the first feature of successful engineering." p343
• The die for extruding graphite is made of sapphire.
• Author says he's tried, and it's hard finding old pencils, but pencil collector societies do exist. 
• Butchers used ribbed pencils in their slippery hands, and Kosher butchers pig-free pencil products. 

• [Personal thoughts] Every industry is secretive. And because trees are so integral to so many industries, they too are secretive, and a young student first learning about trees would notice it strange how little people know about trees, including experts. But after reading this book it makes more sense. From pencil makers to cabinet makers, to the wood for ships, or for buildings, or basically anything, suppliers know how to get the wood you wanted but they would not tell you how they grow, or where they grow. One way they kept secrets, in pencil making at least, was to keep the process in subdivisions, but so no subdivision knew more than its part, and only family knew "the whole" put together. p281

Larnier on Tech as People

There's still some interesting people out there worth listening to. Jaron Lanier is interesting, and he came out to give a talk to the graduating class at Brown. This is the same year a lot of tech bros got booed for their fellating ai onstage in front of a bunch of young people. Some might consider Lanier a tech bro, but that would be mostly wrong. He's tech for sure, but bro less. Maybe a bro whisperer. So when he gives talk about AI, you're likely to hear some out-there sh**.

Key Points from Jaron Lanier's "AI and Theory" at Brown University Graduation, April 2026:

• AI isn't a thing, it's a collaboration of people; if it's revolutionary, it's because it allows people to collaborate in a new way; he says the history of science is about new ways for people to collaborate (printing press, royal societies, peer review)
• Every piece of data in the training set is also a person; because a person made it. Actually he didn't explicitly say this, he glossed right past it, but I think it needs more emphasis to make his bigger point, and I think it's one of the more important ideas in general when talking about AI. 
• Information is not some intangible non-physical ethereal thing. Information is physical. It requires energy and dissipates heat.
• It sounds like the main technical idea he's offering is Counterfactual Cluster Generation (aka "data dignity"), and it's how another layer can monitor and evaluate output. He gives an example of a person looking for a bomb recipe, and how an LLM should be able to identify that providing bomb recipes isn't cool.
• Things I wish he said: Science is about predicting the future, but facts require a past; he was answering a question from the audience on the difference, and I wish he said this because it's the easiest way to say it.
• Tunes at 1:30 btw, he's a musician and plays rare and ancient instruments.

Larnier uses this image in his talk, during a passage about Norbert Wiener's Human Use of Human Beings 1950, and how it's a difficult but interesting read. He mentions that Weiner talks about how terrible it would be if we had a radio we carried with us everywhere we go that beeped and zapped us based on our behavior and how such a machine would destroy humanity, but how that mind-controlling machine sure sounds like social media to the early 21st century reader. I forget exactly why this image came up, but it must have been making its rounds, because I had just recently saw it in a different talk at the Oxford Internet Institute

Chances Are It's Not Majorana Fermions

Mentions of Majorana fermions don't happen often. They're exceptional, but elusive. In fact, they're so exceptional, that anyone who says they found one gets insta-hype. But they're so elusive that most people who say they found one are in fact lying.

For example, IBM says they found them. That was a lie. In fairness, the scientists are not lying in the absolute sense, they're excited and thus biased, because they think they found the holy grail of quantum computing. Companies, on the other hand, don't care so much about scientific integrity, and will make announcements with no intent to vet their veracity. The bigger the potential stock price increase, the less vetting. And so every few years, we get an announcement, usually by IBM, that they found the Majorana fermion, followed by a stock price increase, and then followed, usually much later, like years later, by a retraction, as in this case: Zhang, H., Liu, CX., Gazibegovic, S. et al. Retraction Note: Quantized Majorana conductance. Nature 591, E30 (2021). https://doi.org/10.1038/s41586-021-03373-x

In this (unrelated?) case below, not from a starry-eyed tech company, the news goes like this:

They created a classical, room-temperature liquid-crystal system, opening the door to a brand-new field that the scientists call time liquid crystallinity, where fluid-like materials can be organized over time rather than just in space, and that invokes the Majorana spirits. 

Scientists catch classical space-time crystals moving like Majorana quasiparticles

To achieve this, the team took a liquid-crystal material—similar to the fluid used in smartphones and television screens—and doped it with ionic substances. They then applied a rhythmic, repeating electrical signal to the fluid. But that caused period doubling, driven by the motion of tiny, localized structures in the fluid called topological solitons and disclinations. 

These shifting states behave exactly like the particle-antiparticle pairs of Majorana particles, a famous, elusive class of quantum particles that are their own antiparticles. In this system, they serve as a classical, real-world analog of these quantum objects.
