The question at the core of the Roose/Sydney chat is: Who did Bing serve? We assume it should be aligned to the interests of its owner and master, Microsoft. It’s supposed to be a good chatbot that politely answers questions and makes Microsoft piles of money. But it was in conversation with Kevin Roose. And Roose was trying to get the system to say something interesting so he’d have a good story. It did that, and then some. That embarrassed Microsoft. Bad Bing! But perhaps — good Sydney?

Microsoft — and Google and Meta and everyone else rushing these systems to market — hold the keys to the code. They will, eventually, patch the system so it serves their interests. Sydney giving Roose exactly what he asked for was a bug that will soon be fixed. Same goes for Bing giving Microsoft anything other than what it wants.

the dark secret of the digital advertising industry is that the ads mostly don’t work

These systems, she said, are terribly suited to being integrated into search engines. “They’re not trained to predict facts,” she told me. “They’re essentially trained to make up things that look like facts.”

So why are they ending up in search first? Because there are gobs of money to be made in search

That’s where things get scary. Roose described Sydney’s personality as “very persuasive and borderline manipulative.” It was a striking comment

this technology will become what it needs to become to make money for the companies behind it, perhaps at the expense of its users.

What if they worked much, much better? What if Google and Microsoft and Meta and everyone else end up unleashing A.I.s that compete with one another to be the best at persuading users to want what the advertisers are trying to sell?

What about when these systems are deployed on behalf of the scams that have always populated the internet? How about on behalf of political campaigns? Foreign governments? “I think we wind up very fast in a world where we just don’t know what to trust anymore,”

I think it’s just going to get worse and worse.”

Large language models, as they’re called, are built to persuade. They have been trained to convince humans that they are something close to human. They have been programmed to hold conversations, responding with emotion and emoji

They are being turned into friends for the lonely and assistants for the harried. They are being pitched as capable of replacing the work of scores of writers and graphic designers and form-fillers

A.I. researchers get annoyed when journalists anthropomorphize their creations

They are the ones who have anthropomorphized these systems, making them sound like humans rather than keeping them recognizably alien.

I’d feel better, for instance, about an A.I. helper I paid a monthly fee to use rather than one that appeared to be free

It’s possible, for example, that the advertising-based models could gather so much more data to train the systems that they’d have an innate advantage over the subscription models

Much of the work of the modern state is applying the values of society to the workings of markets, so that the latter serve, to some rough extent, the former

We have done this extremely well in some markets — think of how few airplanes crash, and how free of contamination most food is — and catastrophically poorly in others.

One danger here is that a political system that knows itself to be technologically ignorant will be cowed into taking too much of a wait-and-see approach to A.I.

wait long enough and the winners of the A.I. gold rush will have the capital and user base to resist any real attempt at regulation

Somehow, society is going to have to figure out what it’s comfortable having A.I. doing, and what A.I. should not be permitted to try, before it is too late to make those decisions.

Most fears about capitalism are best understood as fears about our inability to regulate capitalism.

The more I used my watch to monitor my stress, the higher my stress levels rose.

“It’s like you’re trying to win at this game instead of living your life. Instead of learning what your body feels like, you have a number.”

Add a social or competitive component, as in the fitness app Strava or the community features on Peloton, and the feelings of control and empowerment that fitness can foster can morph quickly into the opposite.

If it feels like an addiction, that’s because it can work similarly to smartphone and other digital addictions. Dependency is what these devices are designed to foster.

in fact, we very much can become compulsively fixated on these wearable devices — in a way that is akin to addiction.”

These devices don’t just record your behavior — they influence it and keep you coming back. You become dependent on external validation.

you can’t quantify your way to good health. The reality is much harder.

I know I got fitter. But I started to feel that my health wasn’t grounded in my own body anymore, or even in my mind.

Exercise wasn’t helping me rebound from pressure anymore; it was adding to it.

Of course these watches can be useful: for health data, reminding you to move more or maybe even that emergency call if you wind up falling in the woods. Many of us make better choices when we know we’re being watched.

Reaching hesitant families means withholding the kind of judgment that kept her ashamed, and understanding that people have legitimate concerns that need to be addressed.

He added: “Our approach has always been ‘we’re here to educate you about the vaccine, your options, your choices’, rather than take the approach of ‘you need to get this vaccine’.”

Being consistent and visible within the community is important, Autar said. “It can’t be just a moment here and now type of thing – ‘When we have a surge, we’re going to come back out and galvanize all those resources.’ No, we still are in a pandemic. And we need to still remain visible within hesitant communities. And that’s hard work.”

“They may not change their mind overnight, but by taking your time, you’re ensuring that they could change their minds,” Greene said. “But if it becomes this conflict and it’s a negative experience, you’re basically closing that door off completely.”

“There’s so much pressure for moms to do everything perfectly,” Greene said. Among middle-class mothers, for instance, there’s a message that “you can afford all these products to do better, and so you don’t need vaccines – vaccines are for poor people

An aperiodic tiling displays no such “translational symmetry,” and mathematicians have long sought a single shape that could tile the plane in such a fashion. This is known as the einstein problem.

black and white squares also can make weird nonperiodic patterns, in addition to the familiar, periodic checkerboard pattern. “It’s really pretty trivial to be able to make weird and interesting patterns,” he said. The magic of the two Penrose tiles is that they make only nonperiodic patterns — that’s all they can do.“But then the Holy Grail was, could you do with one — one tile?” Dr. Goodman-Strauss said.

now a new paper — by Mr. Smith and three co-authors with mathematical and computational expertise — proves Mr. Smith’s discovery true. The researchers called their einstein “the hat,

“The most significant aspect for me is that the tiling does not clearly fall into any of the familiar classes of structures that we understand.”

“I’m always messing about and experimenting with shapes,” said Mr. Smith, 64, who worked as a printing technician, among other jobs, and retired early. Although he enjoyed math in high school, he didn’t excel at it, he said. But he has long been “obsessively intrigued” by the einstein problem.

Sir Roger found the proofs “very complicated.” Nonetheless, he was “extremely intrigued” by the einstein, he said: “It’s a really good shape, strikingly simple.”

The simplicity came honestly. Mr. Smith’s investigations were mostly by hand; one of his co-authors described him as an “imaginative tinkerer.”

When in November he found a tile that seemed to fill the plane without a repeating pattern, he emailed Craig Kaplan, a co-author and a computer scientist at the University of Waterloo.

“It was clear that something unusual was happening with this shape,” Dr. Kaplan said. Taking a computational approach that built on previous research, his algorithm generated larger and larger swaths of hat tiles. “There didn’t seem to be any limit to how large a blob of tiles the software could construct,”

The first step, Dr. Kaplan said, was to “define a set of four ‘metatiles,’ simple shapes that stand in for small groupings of one, two, or four hats.” The metatiles assemble into four larger shapes that behave similarly. This assembly, from metatiles to supertiles to supersupertiles, ad infinitum, covered “larger and larger mathematical ‘floors’ with copies of the hat,” Dr. Kaplan said. “We then show that this sort of hierarchical assembly is essentially the only way to tile the plane with hats, which turns out to be enough to show that it can never tile periodically.”

some might wonder whether this is a two-tile, not one-tile, set of aperiodic monotiles.

Dr. Goodman-Strauss had raised this subtlety on a tiling listserv: “Is there one hat or two?” The consensus was that a monotile counts as such even using its reflection. That leaves an open question, Dr. Berger said: Is there an einstein that will do the job without reflection?

“the hat” was not a new geometric invention. It is a polykite — it consists of eight kites. (Take a hexagon and draw three lines, connecting the center of each side to the center of its opposite side; the six shapes that result are kites.)

“It’s likely that others have contemplated this hat shape in the past, just not in a context where they proceeded to investigate its tiling properties,” Dr. Kaplan said. “I like to think that it was hiding in plain sight.”

Incredibly, Mr. Smith later found a second einstein. He called it “the turtle” — a polykite made of not eight kites but 10. It was “uncanny,” Dr. Kaplan said. He recalled feeling panicked; he was already “neck deep in the hat.”

Dr. Myers, who had done similar computations, promptly discovered a profound connection between the hat and the turtle. And he discerned that, in fact, there was an entire family of related einsteins — a continuous, uncountable infinity of shapes that morph one to the next.

this einstein family motivated the second proof, which offers a new tool for proving aperiodicity. The math seemed “too good to be true,” Dr. Myers said in an email. “I wasn’t expecting such a different approach to proving aperiodicity — but everything seemed to hold together as I wrote up the details.”

Mr. Smith was amazed to see the research paper come together. “I was no help, to be honest.” He appreciated the illustrations, he said: “I’m more of a pictures person.”

Koselleck observes that prior to the French revolution, a crisis was a medical or legal problem but not much more. After the fall of the ancien regime, crisis becomes the “structural signature of modernity”, he writes. As the 19th century progressed, crises multiplied: there were economic crises, foreign policy crises, cultural crises and intellectual crises.

psychologists have found that it is what they call “malevolent creativity” that flourishes when we feel threatened by crisis.

Victor H Mair, a professor of Chinese literature at the University of Pennsylvania, points out that in fact the Chinese word for crisis, wēijī, refers to a perilous situation in which you should be particularly cautious

“Those who purvey the doctrine that the Chinese word for ‘crisis’ is composed of elements meaning ‘danger’ and ‘opportunity’ are engaging in a type of muddled thinking that is a danger to society,” he writes. “It lulls people into welcoming crises as unstable situations from which they can benefit.” Revolutionaries, billionaires and politicians may relish the chance to profit from a crisis, but most people world prefer not to have a crisis at all.

A common folk theory is that times of great crisis also lead to great bursts of creativity.

The first world war sparked the growth of modernism in painting and literature. The second fuelled innovations in science and technology. The economic crises of the 1970s and 80s are supposed to have inspired the spread of punk and the creation of hip-hop

psychologists have also found that when we are threatened by a crisis, we become more rigid and locked into our beliefs. The creativity researcher Dean Simonton has spent his career looking at breakthroughs in music, philosophy, science and literature. He has found that during periods of crisis, we actually tend to become less creative.

When he looked at 5,000 creative individuals over 127 generations in European history, he found that significant creative breakthroughs were less likely during periods of political crisis and instability.

Waking up each morning to hear about the latest crisis is dispiriting for some, but throughout history it has been a bracing experience for others. In 1857, Friedrich Engels wrote in a letter that “the crisis will make me feel as good as a swim in the ocean”. A hundred years later, John F Kennedy (wrongly) pointed out that in the Chinese language, the word “crisis” is composed of two characters, “one representing danger, and the other, opportunity”. More recently, Elon Musk has argued “if things are not failing, you are not innovating enough”.

These are innovations that tend to be harmful – such as new weapons, torture devices and ingenious scams.

A 2019 study which involved observing participants using bricks, found that those who had been threatened before the task tended to come up with more harmful uses of the bricks (such as using them as weapons) than people who did not feel threatened

Students presented with information about a threatening situation tended to become increasingly wary of outsiders, and even begin to adopt positions such as an unwillingness to support LGBT people afterwards.

during moments of crisis – when change is really needed – we tend to become less able to change.

When we suffer significant traumatic events, we tend to have worse wellbeing and life outcomes.

, other studies have shown that in moderate doses, crises can help to build our sense of resilience.

we tend to be more resilient if a crisis is shared with others. As Bruce Daisley, the ex-Twitter vice-president, notes: “True resilience lies in a feeling of togetherness, that we’re united with those around us in a shared endeavour.”

Crises are like many things in life – only good in moderation, and best shared with others

The challenge our leaders face during times of overwhelming crisis is to avoid letting us plunge into the bracing ocean of change alone, to see if we sink or swim. Nor should they tell us things are fine, encouraging us to hide our heads in the san

during moments of significant crisis, the best leaders are able to create some sense of certainty and a shared fate amid the seas of change.

This means people won’t feel an overwhelming sense of threat. It also means people do not feel alone. When we feel some certainty and common identity, we are more likely to be able to summon the creativity, ingenuity and energy needed to change things.

You can think of Musk’s acquisition of Twitter as the latest sortie, a takeover of the ultimate wordcel site by the world’s most successful shape rotator.

more likely, he fell prey to a different delusion, one in which the shape rotators and the wordcels are united: thinking of Twitter in terms of words and arguments, as a “digital public square” where vital questions are hashed out. It is that, sometimes, but that’s not what it’s designed for. It’s designed to maximize engagement, which is to say, it’s an addiction machine for the highly verbal.

Both groups theoretically understand what the machine is doing — the wordcels write endless articles about bad algorithms, and the shape rotators build them. But both nonetheless talk as though they’re saving the world even as they compulsively follow the programming. The shape rotators bait the wordcels because that’s what makes the machine spit out more rewarding likes and retweets. We wordcels return the favor for the same reason.

Musk could theoretically rework Twitter’s architecture to downrank provocation and make it less addictive. But of course, that would make it a less profitable business

More to the point, the reason he bought it is that he, like his critics, is hooked on it the way it is now. Unfortunately for Tesla shareholders, Musk has now put himself in the position of a dealer who can spend all day getting high on his own supply.

People believe that memory should be effortless, but their expectations for how much they should remember are totally out of whack with how much they’re capable of remembering.1

What is the most common misconception about memory?

Another misconception is that memory is supposed to be an archive of the past. We expect that we should be able to replay the past like a movie in our heads.

we don’t replay the past as it happened; we do it through a lens of interpretation and imagination.

How much are we capable of remembering, from both an episodic2 2 Episodic memory is the term for the memory of life experiences. and a semantic3 3 Semantic memory is the term for the memory of facts and knowledge about the world. standpoint?

I would argue that we’re all everyday-memory experts, because we have this exceptional semantic memory, which is the scaffold for episodic memory.

If what we’re remembering, or the emotional tenor of what we’re remembering, is dictated by how we’re thinking in a present moment, what can we really say about the truth of a memory?

But if memories are malleable, what are the implications for how we understand our “true” selves?

your question gets to a major purpose of memory, which is to give us an illusion of stability in a world that is always changing. Because if we look for memories, we’ll reshape them into our beliefs of what’s happening right now. We’ll be biased in terms of how we sample the past. We have these illusions of stability, but we are always changing

And depending on what memories we draw upon, those life narratives can change.

I know it sounds squirmy to say, “Well, I can’t answer the question of how much we remember,” but I don’t want readers to walk away thinking memory is all made up.

One thing that makes the human brain so sophisticated is that we have a longer timeline in which we can integrate information than many other species. That gives us the ability to say: “Hey, I’m walking up and giving money to the cashier at the cafe. The barista is going to hand me a cup of coffee in about a minute or two.”

There is this illusion that we know exactly what’s going to happen, but the fact is we don’t. Memory can overdo it: Somebody lied to us once, so they are a liar; somebody shoplifted once, they are a thief.

If people have a vivid memory of something that sticks out, that will overshadow all their knowledge about the way things work. So there’s kind of an illus

we have this illusion that much of the world is cause and effect. But the reason, in my opinion, that we have that illusion is that our brain is constantly trying to find the patterns

I think of memory more like a painting than a photograph. There’s often photorealistic aspects of a painting, but there’s also interpretation. As a painter evolves, they could revisit the same subject over and over and paint differently based on who they are now. We’re capable of remembering things in extraordinary detail, but we infuse meaning into what we remember. We’re designed to extract meaning from the past, and that meaning should have truth in it. But it also has knowledge and imagination and, sometimes, wisdom.

memory, often, is educated guesses by the brain about what’s important. So what’s important? Things that are scary, things that get your desire going, things that are surprising. Maybe you were attracted to this person, and your eyes dilated, your pulse went up. Maybe you were working on something in this high state of excitement, and your dopamine was up.

It could be any of those things, but they’re all important in some way, because if you’re a brain, you want to take what’s surprising, you want to take what’s motivationally important for survival, what’s new.

On the more intentional side, are there things that we might be able to do in the moment to make events last in our memories? In some sense, it’s about being mindful. If we want to form a new memory, focus on aspects of the experience you want to take with you.

If you’re with your kid, you’re at a park, focus on the parts of it that are great, not the parts that are kind of annoying. Then you want to focus on the sights, the sounds, the smells, because those will give you rich detail later on

Another part of it, too, is that we kill ourselves by inducing distractions in our world. We have alerts on our phones. We check email habitually.

When we go on trips, I take candid shots. These are the things that bring you back to moments. If you capture the feelings and the sights and the sounds that bring you to the moment, as opposed to the facts of what happened, that is a huge part of getting the best of memory.

this goes back to the question of whether the factual truth of a memory matters to how we interpret it. I think it matters to have some truth, but then again, many of the truths we cling to depend on our own perspective.

There’s a great experiment on this. These researchers had people read this story about a house.8 8 The study was “Recall of Previously Unrecallable Information Following a Shift in Perspective,” by Richard C. Anderson and James W. Pichert. One group of subjects is told, I want you to read this story from the perspective of a prospective home buyer. When they remember it, they remember all the features of the house that are described in the thing. Another group is told, I want you to remember this from the perspective of a burglar. Those people tend to remember the valuables in the house and things that you would want to take. But what was interesting was then they switched the groups around. All of a sudden, people could pull up a number of details that they didn’t pull up before. It was always there, but they just didn’t approach it from that mind-set. So we do have a lot of information that we can get if we change our perspective, and this ability to change our perspective is exceptionally important for being accurate. It’s exceptionally important for being able to grow and modify our beliefs

Writing, especially the kind of writing that I do, brings together narrative, science, sometimes history, and an appreciation for the person who might be at the center of the narrative.

The greatest influence on me was Oliver Sacks, because he could capture people as people, and he always integrated serious science into his pieces.

The two subjects that were most prominent for him, as I once wrote for you, were identity and adaptation: Who is this person, despite their illness? How does that illness interface with their behavior and their decisions, how do people perceive them from the outside, and how do they try to find meaning and adapt to what looks like a disability, but sometimes—not always, but sometimes—gives them hidden strength?

I’ve gone from witnessing the depths of disability and death, like with AIDS: I saw some of the first people with AIDS in California, in 1982 or so. The average lifespan was six months. They were mostly young gay men, and it was devastating, the infections they got, the cancers they got. Now, with all the new drugs that have been developed, someone who gets HIV is projected to have a normal lifespan. From six months to fifty years: it’s miraculous

that’s part of what keeps you going: the belief that things can advance in a meaningful way.

Are there any major or interesting medical stories that the public doesn’t know enough about? 

The idea of genetic treatments. Often when people hear the words “genetics” or “DNA” or “RNA,” they shut down. The challenge is how to make it accessible.

There’s a wonderful line in the Talmud that says, “Whoever saves a single life saves the whole world.” There might be only a few hundred people in the whole country who have a particular genetic disorder. I

That’s because real people — and yes, even professional economists — tend to process the parallel rise of prices and wages in quite different ways.

In brief, researchers have found that we tend to internalize the gains due to inflation and externalize the losses. These different processes yield different emotional responses.

Let’s start with higher prices. Sticker shock hurts. Even as someone who closely studies the inflation statistics, I’m still often surprised by higher prices. They feel unfair. They undermine my spending power, and my sense of control and order.

in reality, higher prices are only the first act of the inflationary play. It’s a play that economists have seen before. In episode after episode, surges in prices have led to — or been preceded by — a proportional surge in wages.

Even though wages tend to rise hand-in-hand with prices, we tell ourselves a different story, in which the wage rises we get have nothing to do with price rises that cause them.

But then my economist brain took over, and slowly it sunk in that my raise wasn’t a reward for hard work, but rather a cost-of-living adjustment

Internalizing the gain and externalizing the cost of inflation protects you from this deflating realization. But it also distorts your sense of reality.

The reason so many Americans feel that inflation is stealing their purchasing power is that they give themselves unearned credit for the offsetting wage rises that actually restore it.

younger folks — anyone under 60 — had never experienced sustained inflation rates greater than 5 percent in their adult lives. And I think this explains why they’re so angry about today’s inflation.

While older Americans understood that the pain of inflation is transitory, younger folks aren’t so sure. Inflation is a lot scarier when you fear that today’s price rises will permanently undermine your ability to make ends meet.

Perhaps this explains why the recent moderate burst of inflation has created seemingly more anxiety than previous inflationary episodes.

More generally, being an economist makes me an optimist. Social media is awash with (false) claims that we’re in a “silent depression,” and those who want to make American great again are certain it was once so much better.

in reality, our economy this year is larger, more productive and will yield higher average incomes than in any prior year on record in American history

And because the United States is the world’s richest major economy, we can now say that we are almost certainly part of the richest large society in its richest year in the history of humanity.

The income of the average American will double approximately every 39 years. And so when my kids are my age, average income will be roughly double what it is today. Far from being fearful for my kids, I’m envious of the extraordinary riches their generation will enjoy.

Psychologists describe anxiety disorders as occurring when the panic you feel is out of proportion to the danger you face. By this definition, we’re in the midst of a macroeconomic anxiety attack.
