, we know from the science of linguistics and the philosophy of knowledge that they differ profoundly from how humans reason and use language. These differences place significant limitations on what these programs can do, encoding them with ineradicable defects.

It is at once comic and tragic, as Borges might have noted, that so much money and attention should be concentrated on so little a thing — something so trivial when contrasted with the human mind, which by dint of language, in the words of Wilhelm von Humboldt, can make “infinite use of finite means,” creating ideas and theories with universal reach.

The human mind is not, like ChatGPT and its ilk, a lumbering statistical engine for pattern matching, gorging on hundreds of terabytes of data and extrapolating the most likely conversational response or most probable answer to a scientific question

the human mind is a surprisingly efficient and even elegant system that operates with small amounts of information; it seeks not to infer brute correlations among data points but to create explanations

such programs are stuck in a prehuman or nonhuman phase of cognitive evolution. Their deepest flaw is the absence of the most critical capacity of any intelligence: to say not only what is the case, what was the case and what will be the case — that’s description and prediction — but also what is not the case and what could and could not be the case

Those are the ingredients of explanation, the mark of true intelligence.

Here’s an example. Suppose you are holding an apple in your hand. Now you let the apple go. You observe the result and say, “The apple falls.” That is a description. A prediction might have been the statement “The apple will fall if I open my hand.”

an explanation is something more: It includes not only descriptions and predictions but also counterfactual conjectures like “Any such object would fall,” plus the additional clause “because of the force of gravity” or “because of the curvature of space-time” or whatever. That is a causal explanation: “The apple would not have fallen but for the force of gravity.” That is thinking.

The crux of machine learning is description and prediction; it does not posit any causal mechanisms or physical laws

any human-style explanation is not necessarily correct; we are fallible. But this is part of what it means to think: To be right, it must be possible to be wrong. Intelligence consists not only of creative conjectures but also of creative criticism. Human-style thought is based on possible explanations and error correction, a process that gradually limits what possibilities can be rationally considered.

ChatGPT and similar programs are, by design, unlimited in what they can “learn” (which is to say, memorize); they are incapable of distinguishing the possible from the impossible.

Whereas humans are limited in the kinds of explanations we can rationally conjecture, machine learning systems can learn both that the earth is flat and that the earth is round. They trade merely in probabilities that change over time.

For this reason, the predictions of machine learning systems will always be superficial and dubious.

some machine learning enthusiasts seem to be proud that their creations can generate correct “scientific” predictions (say, about the motion of physical bodies) without making use of explanations (involving, say, Newton’s laws of motion and universal gravitation). But this kind of prediction, even when successful, is pseudoscienc

While scientists certainly seek theories that have a high degree of empirical corroboration, as the philosopher Karl Popper noted, “we do not seek highly probable theories but explanations; that is to say, powerful and highly improbable theories.”

The theory that apples fall to earth because mass bends space-time (Einstein’s view) is highly improbable, but it actually tells you why they fall. True intelligence is demonstrated in the ability to think and express improbable but insightful things.

This means constraining the otherwise limitless creativity of our minds with a set of ethical principles that determines what ought and ought not to be (and of course subjecting those principles themselves to creative criticism)

True intelligence is also capable of moral thinking

To be useful, ChatGPT must be empowered to generate novel-looking output; to be acceptable to most of its users, it must steer clear of morally objectionable content

In 2016, for example, Microsoft’s Tay chatbot (a precursor to ChatGPT) flooded the internet with misogynistic and racist content, having been polluted by online trolls who filled it with offensive training data. How to solve the problem in the future? In the absence of a capacity to reason from moral principles, ChatGPT was crudely restricted by its programmers from contributing anything novel to controversial — that is, important — discussions. It sacrificed creativity for a kind of amorality.

Here, ChatGPT exhibits something like the banality of evil: plagiarism and apathy and obviation. It summarizes the standard arguments in the literature by a kind of super-autocomplete, refuses to take a stand on anything, pleads not merely ignorance but lack of intelligence and ultimately offers a “just following orders” defense, shifting responsibility to its creators.

In short, ChatGPT and its brethren are constitutionally unable to balance creativity with constraint. They either overgenerate (producing both truths and falsehoods, endorsing ethical and unethical decisions alike) or undergenerate (exhibiting noncommitment to any decisions and indifference to consequences). Given the amorality, faux science and linguistic incompetence of these systems, we can only laugh or cry at their popularity.

We need not wonder what the basic objections will be: Third Wave Antiracism isn’t really a religion; I am oversimplifying; I shouldn’t write this without being a theologian; it is a religion but it’s a good one; and so on

It is not an argument against protest

I am not writing this thinking of right-wing America as my audience.

This is not merely a complaint.

Our current conversations waste massive amounts of energy in missing the futility of “dialogue” with them. Of a hundred fundamentalist Christians, how many do you suppose could be convinced via argument to become atheists? There is no reason that the number of people who can be talked out of the Third Wave Antiracism religion is any higher.

our concern must be how to continue with genuine progress in spite of this ideology. How do we work around it?

My interest is not “How do we get through to these people?” We cannot, at least not enough of them to matte

We seek change in the world, but for the duration will have to do so while encountering bearers of a gospel, itching to smoke out heretics, and ready on a moment’s notice to tar us as moral perverts.

We will term these people The Elect. They do think of themselves as bearers of a wisdom, granted them for any number of reasons—a gift for empathy, life experience, maybe even intelligence.

they see themselves as having been chosen, as it were, by one or some of these factors, as understanding something most do not.

“The Elect” is also good in implying a certain smugness, which is sadly accurate as a depiction.

But most importantly, terming these people The Elect implies a certain air of the past, à la Da Vinci Code. This is apt, in that the view they think of as sacrosanct is directly equivalent to views people centuries before us were as fervently devoted to as today’s Elect are

Following the religion means to pillory people for what, as recently as 10 years ago, would have been thought of as petty torts or even as nothing at all; to espouse policies that hurt black people as long as supporting them makes you seem aware that racism exists;

o pretend that America never makes any real progress on racism; and to almost hope that it doesn’t because this would deprive you of a sense of purpose.

There were plenty of books about Black people, but they tended to be about poor or working-class Black people and often depicted Black lives proscribed by discrimination and inequality

I was aware of two instances of myself in fiction of the time. One was the nerdy teenage middle-class Black girl in Louise Fitzhugh’s “Nobody’s Family Is Going to Change.” Then there was “Sarah Phillips” by Andrea Lee in 1984. That one was a near-sacred experience for me, in depicting a middle-class Black girl who grew up outside Philadelphia, went to Harvard and then moved to Europe. Here was someone I could have been, a variation on some people I knew

But I neither needed nor sought out more such books. How much me did I need? I read to learn about what I didn’t know.

when I started my graduate study, I explicitly did not want to study Black English. It was too close to home.

What fascinated me, and still does, are languages utterly unlike the one I grew up with. This is what I do my academic work on. I am happy to write about Black English, but I do it out of civic duty. What first hooked me on languages was hearing someone speak Hebrew

This idea that one, if brown, is to seek one’s self in what one reads and watches gets around quite a bit.

But still, the idea that Black people are deprived in not exploring what they already relate to is not as natural as it sounds.

This position is rooted, one suspects, as a defense against racism, in a sense that learning most meaningfully takes place within a warm comfort zone of cultural membership. But it’s a wide, wide world out there, and this position ultimately limits the mind and the soul.

I question its necessity in 2023. The etymology of the word “education” is related to the Latin “educere,” meaning to lead outward, not inward.

It can be especially ticklish to hear white people taking up the idea that Black people stray from their selves when taking up things beyond Blackness

I sense the idea that real Blackness means ever seeking yourself in your reading and viewing is a post-1966 thing, to refer to what I wrote here last week.

W.E.B. Du Bois had no such idea. He wrote: “I sit with Shakespeare, and he winces not. Across the color line I move arm in arm with Balzac and Dumas, where smiling men and welcoming women glide in gilded halls. From out the caves of evening that swing between the strong-limbed Earth and the tracery of the stars, I summon Aristotle and Aurelius and what soul I will, and they come all graciously with no scorn nor condescension.”

Du Bois adapted these “white” works to his own needs and predilections. Even the naked racism he lived with daily did not lead him to draw a line around “white” things as something alien to his essence

Rather, he insisted that these works were, in fact, part of his self, regardless of how wider society saw that self or how figures like Shakespeare and Aristotle would have seen him.

Du Bois, in this, was normal. Today I sit with “Succession,” Steely Dan and Saul Bellow, and they wince not. I see myself in none of them. Yes, Bellow had some nasty moments on race, such as a gruesomely prurient scene in “Mr. Sammler’s Planet.” But I’m sorry: I cannot let that one scene — or even two — deprive me of the symphonic reaches of “Herzog” and “Humboldt’s Gift.” What they offer, after all, becomes part of me along with everything else.

the truth is that characters I can see as me are now not uncommon on television in particular. Andre Braugher’s Captain Holt on “Brooklyn Nine-Nine” was about as close to me as I expect a sitcom character ever to be, for example. That was fun. But honestly, I didn’t need it. I live with me. I watch TV to see somebody else.

Even more absurd is the idea of giving unaccountable tech chiefs some moral licence to pronounce on good and evil, right and wrong, and what is best for the world.

Over the years, we have seen huge setbacks to the progress of liberal and democratic institutions, with the rise of fascism and communism in the 1930s, or the military coups and oil crises of the 1960s and ’70s. And yet, liberal democracy has endured and come back repeatedly, because the alternatives are so bad. People across varied cultures do not like living under dictatorship, and they value their individual freedom. No authoritarian government presents a society that is, in the long term, more attractive than liberal democracy, and could therefore be considered the goal or endpoint of historical progress.

The philosopher Hegel coined the phrase the end of history to refer to the liberal state’s rise out of the French Revolution as the goal or direction toward which historical progress was trending. For many decades after that, Marxists would borrow from Hegel and assert that the true end of history would be a communist utopia. When I wrote an article in 1989 and a book in 1992 with this phrase in the title, I noted that the Marxist version was clearly wrong and that there didn’t seem to be a higher alternative to liberal democracy.

setbacks do not mean that the underlying narrative is wrong. None of the proffered alternatives look like they’re doing any better.

Liberal democracy will not make a comeback unless people are willing to struggle on its behalf. The problem is that many who grow up living in peaceful, prosperous liberal democracies begin to take their form of government for granted. Because they have never experienced an actual tyranny, they imagine that the democratically elected governments under which they live are themselves evil dictatorships conniving to take away their rights

Functional Medicine isn't a protected title and a medical qualification isn't a prerequisite to practice. The result is an unregulated and disparate field, with medical doctors, nutritionists, naturopaths and homeopaths among the many practitioners.

Some other chronic illnesses the field claims to treat include heart disease, type 2 diabetes, irritable bowel syndrome, ulcerative colitis, depression, anxiety and arthritis

ll kinds of different reasons, some might have gluten issues, gut issues, others might have a deficiency causing neurological issues, MS is a symptom."

"There are components of Functional Medicine that absolutely lack an evidence base and there are practitioners of what they call Functional Medicine, they charge people for intravenous nutritional injections, they exaggerate claims, and that is professionally inappropriate, unethical and it lacks evidence.

On Dr Mark Hyman's view of MS he says, "there are a lot of terms put together there, all of which individually make a lot of sense, but put together in that way they do not.

"What does FM actually mean? It means nothing. It's a gift-gallop of words thrown together. It's criticised by advocates of evidence-based medicine because it's giving a veneer of scientific legitimacy to ideas that are considered pseudoscientific. For example, it'll take alternative medicine modalities like homeopathy and then call them 'bio-infusions' or something similar, rebranding it as something that works.

"It's a redundant name, real medicine is functional."

Next month the third annual Lifestyle and Functional Medical conference will take place in Salthill, Galway on November 3. Last year's event was attended by more than 500 people and featured a keynote address by honorary consultant cardiologist Dr Aseem Malhotra, author of bestselling The Pioppi Diet (which was named one of the top five worst celebrity diets to avoid in 2018 by the British Dietetic Foundation).

Dr David Robert Grimes is physicist and visiting fellow of Oxford and QUB. His research into cancer focuses on modelling tumour metabolism and radiation interactions. For Dr Grimes, the lack of definition, or "double-speak" as he puts it, in FM is troubling.

As well as the cost of appointments, FM practitioners commonly charge extra for tests. An omega finger prick test is around €100. A vitamin D test can cost upwards of €60, full thyroid panel more than €150 and a gut function test €400. Prices vary between practitioners.

"If I, as a GP, engaged in some of these behaviours I would be struck off." Specifically? "If I was recommending treatments that lacked an evidence base, or if I was promoting diagnostic tests which are expensive and lack an evidence base.

GPs engage every year in ongoing continuous professional development, I spend my evenings and my weekends outside of working hours attending educational events, small-group learning, large-group learning, engaging in research. This is an accusation that was levelled at the profession 30 years ago and then it was correct, but the profession has caught up…

"Obviously promoting wellness and healthy diet is very welcome but going beyond that and stating that certain aspects of 'functional medicine' can lead to reduced inflammation or prevent cancer, we have to be very careful about those claims.

Often the outcome of such tests are seemingly 'benign' prescriptions of vitamins or cleanses. However, dietitian Orla Walsh stresses that even these can have potentially harmful effects, especially on "vulnerable" patients, if not prescribed judiciously.

FM has five basic principles. 1. We are all genetically and biochemically unique so it treats the individual, not the disease. 2. It's science-based. 3. The body is intelligent and has the capacity for self-regulation. 4. The body has the ability to heal and prevent nearly all the diseases of ageing. 5. Health is not just the absence of disease, but a state of immense vitality.

She began her Functional Medicine career while training as a medical doctor and now travels the world working with high-profile clients. Dr McHale charges €425 for an initial consultation and €175 for follow-up appointments. Straightforward lab tests are €250 to €750, for complex cases testing fees can be up to €2,000.

"The term [Functional Medicine] tends to be bandied around quite a bit. Other things people say, such as 'functional nutritionist', can be misleading as a term. Many people are Functional Medicine practitioners but don't have any real medical background at all... I think regulation is always probably the best way forward."

"There's an awful lot to it in terms of biochemistry and physiology," she says. "You do need to have a very solid and well ingrained bio-chemistry background. A solely clinical background doesn't equip you with the knowledge to read a test.

"Evidence-base is the cornerstone of medicine and that has to be maintained. It becomes problematic in this area because you are looking at personalised medicine and that can be very difficult to evidence-base."

GP Christine Ritter travelled from England to attend the Galway conference last year with a view to integrating Functional Medicine into her practice.

"It was very motivating," she says. "Where it wasn't perhaps as strong was to find the evidence. The Functional Medicine people would say, 'we've done this study and this trial and we've used this supplement that was successful', but they can't show massive research data which might make it difficult to bring it into the mainstream.

"I also know the rigorous standard of trials we have in medicine they're not usually that great either, it's often driven by who's behind the trial and who's paying for it.

"Every approach that empowers patient to work on their destiny [is beneficial], but you'd have to be mindful that you're not missing any serious conditions."

Dr Hyman is working to grow the evidence-base for Functional Medicine worldwide. "The future is looking very bright," he says. "At the Cleveland Centre we're establishing a research base, building educational platforms, fellowships, residency programmes, rotations. We're advancing the field that's spreading across the world. We're seeing in China the development of a programme of Functional Medicine, South Africa, the UK, in London the Cleveland Clinic will hopefully have a Functional Medicine centre."

For Dr Mark Murphy regulation is a moot point as it can only apply once the field meets the standards of evidence-based medicine.

"Despite well intentioned calls for regulation, complementary and alternative medical therapies cannot be regulated," he says. "Only therapies that possess an evidence-base can enter our standard regulatory processes, including the Irish Medical Council, the Health Products Regulatory Authority and Irish advertising standards. In situations where complementary and alternative therapies develop an evidence base, they are no longer 'complementary and alternative', but in effect they become part of mainstream 'Medicine'.

l What are the principles?

"There's a huge variation between therapists, some are brilliant and some are okay, and some are ludicrous snake oil salesmen."

He is so concerned that patients' health and wealth are being put at risk by alternative therapies that earlier this year he joined Fine Gael TD Kate O'Connell and the Irish Cancer Society in introducing draft legislation earlier this year making it illegal to sell unproven treatments to cancer patients. Violators face jail and heavy fines.

Dr Grimes says criticism of variations in the standards of traditional medical research can be fair, however due to the weight of research it is ultimately self-correcting. He adds, "The reality is that good trials are transparent, independent and pre-registered.

"My involvement in shaping the Bill came from seeing first-hand the exploitation of patients and their families. Most patients undergoing treatment will take some alternative modalities in conjunction but a significant portion are talked out of their conventional medicine and seduced by false promises

. The implicit lesson is that grown-ups aren’t infallible. It’s OK to laugh at them and it’s OK to feel compassion for them and it’s even OK to feel sorry for them on occasion.

The adult figures in children’s literature are also frequently outsiders or eccentrics in some way, and quite often subject to ridicule

yes, adults are often the Other — which makes them a mystery and a curiosity. Literature offers insight into these occasionally intimidating creatures.

In real life, children revere adults and they fear them. It only follows, then, that they appreciate when adult characters behave admirably but also delight in seeing the consequences — especially when rendered with humor — when they don’t.

Nursery rhymes, folk tales, myths and legends overwhelmingly cast adults as their central characters — and have endured for good reason

In somewhat later tales, children investigated crimes alongside Sherlock Holmes, adventured through Narnia, inhabited Oz and traversed Middle-earth. Grown-up heroes can be hobbits, or rabbits (“Watership Down”), badgers or moles (“The Wind in the Willows”). Children join them no matter what because they like to be in league with their protagonists and by extension, their authors.

In children’s books with adult heroes, children get to conspire alongside their elders. Defying the too-often adversarial relationship between adults and children in literature, such books enable children to see that adults are perfectly capable of occupying their shared world with less antagonism — as partners in life, in love and in adventure.

That’s an extraordinary thing to hear from a corporate CEO. Daunt wanted to run a bookstore that was “intellectually satisfying” and “feeds your mind.

If you want to sell music, you must love those songs. If you want to succeed in journalism, you must love those newspapers. If you want to succeed in movies, you must love the cinema.

You don’t fall in love for logical reasons, and you could never convince someone else to do so on the basis of arguments. People either feel it or they don’t. That’s true whether you love your spouse or you love something more intangible like a song or a book or a movie.

But even if you can’t teach this kind of love, you know it when you see it. There are people who are passionate about these things. They believe in them with ardor and devotion. You can find them and hire these people—and those are the individuals you can trust.

In every group chat, no matter the size, participants fall into informal roles. There is usually a leader—a person whose posting frequency drives the group or sets the agenda. Often, there are lurkers who rarely chime in

Larger group chats are not immune to the more toxic dynamics of social media, where competition for attention and herd behavior cause infighting, splintering, and back-channeling.

It’s enough to make one think, as the writer Max Read argued, that “venture-capitalist group chats are a threat to the global economy.” Now you might also say they are a threat to national security.

thanks to the private nature of the group chats, this information largely stayed out of the public eye. As Bloomberg reported, “By the time most people figured out that a bank run was a possibility … it was already well underway.”

The investor panic that led to the swift collapse of Silicon Valley Bank in March was effectively caused by runaway group-chat dynamics. “It wasn’t phone calls; it wasn’t social media,” a start-up founder told Bloomberg in March. “It was private chat rooms and message groups.

Unlike traditional social media or even forums and message boards, group chats are nearly impossible to monitor.

as our digital social lives start to splinter off from feeds and large audiences and into siloed areas, a different kind of unpredictability and chaos awaits. Where social networks create a context collapse—a process by which information meant for one group moves into unfamiliar networks and is interpreted by outsiders—group chats seem to be context amplifiers

group chats provide strong relationship dynamics, and create in-jokes and lore. For decades, researchers have warned of the polarizing effects of echo chambers across social networks; group chats realize this dynamic fully.

Weird things happen in echo chambers. Constant reinforcement of beliefs or ideas might lead to group polarization or radicalization. It may trigger irrational herd behavior such as, say, attempting to purchase a copy of the Constitution through a decentralized autonomous organization

Obsession with in-group dynamics might cause people to lose touch with the reality outside the walls of a particular community; the private-seeming nature of a closed group might also lull participants into a false sense of security, as it did with Teixiera.

the age of the group chat appears to be at least as unpredictable, swapping a very public form of volatility for a more siloed, incalculable version

During our leisure time, not counting work, each of us processes 34 gigabytes, or 100,000 words, every day

The world’s 21,274 television stations produce 85,000 hours of original programming every day as we watch an average of five hours of television daily, the equivalent of 20 gigabytes of audio-video images

That’s not counting YouTube, which uploads 6,000 hours of video every hour.

We’ve created a world with 300 exabytes (300,000,000,000,000,000,000 pieces) of human-made information. If each of those pieces of information were written on a 3-by-5-inch index card and then spread out side by side, just one person’s share—your share of this information—would cover every square inch of Massachusetts and Connecticut combined.

Neurons are living cells with a metabolism; they need oxygen and glucose to survive, and when they’ve been working hard, we experience fatigue. Every status update you read on Facebook, every tweet or text message you get from a friend, is competing for resources in your brain with important things like whether to put your savings in stocks or bonds,

The processing capacity of the conscious mind has been estimated (by the researcher Mihaly Csikszentmihalyi and, independently, by Bell Labs engineer Robert Lucky) at 120 bits per second. That bandwidth, or window, is the speed limit for the traffic of information we can pay conscious attention to at any one time.

While a great deal occurs below the threshold of our awareness, and this has an impact on how we feel and what our life is going to be like, in order for something to become encoded as part of your experience, you need to have paid conscious attention to it.

What does this bandwidth restriction—this information speed limit—mean in terms of our interactions with others? In order to understand one person speaking to us, we need to process 60 bits of information per second. With a processing limit of 120 bits per second, this means you can barely understand two people talking to you at the same time

We’re surrounded on this planet by billions of other humans, but we can understand only two at a time at the most! It’s no wonder that the world is filled with so much misunderstanding.

With such attentional restrictions, it’s clear why many of us feel overwhelmed by managing some of the most basic aspects of life. Part of the reason is that our brains evolved to help us deal with life during the hunter-gatherer phase of human history

Attention is the most essential mental resource for any organism. It determines which aspects of the environment we deal with, and most of the time, various automatic, subconscious processes make the correct choice about what gets passed through to our conscious awareness. For this to happen, millions of neurons are constantly monitoring the environment to select the most important things for us to focus on.

These neurons are collectively the “attentional filter.” They work largely in the background, outside of our conscious awareness. This is why most of the perceptual detritus of our daily lives doesn’t registe

The attentional filter is one of evolution’s greatest achievements. In nonhumans, it ensures that they don’t get distracted by irrelevant things

When our protohuman ancestors left the cover of the trees to seek new sources of food, they simultaneously opened up a vast range of new possibilities for nourishment and exposed themselves to a wide range of new predators. Being alert and vigilant to threatening sounds and visual cues is what allowed them to survive; this meant allowing an increasing amount of information through the attentional filter.

Ten thousand years ago, humans plus their pets and livestock accounted for about 0.1% of the terrestrial vertebrate biomass inhabiting the earth; we now account for 98%

Humans are, by most biological measures, the most successful species our planet has seen. We have managed to survive in nearly every climate our planet has offered (so far), and the rate of our population expansion exceeds that of any other known organism

Our success owes in large part to our cognitive capacity, the ability of our brains to flexibly handle information. But our brains evolved in a much simpler world with far less information coming at us. Today, our attentional filters easily become overwhelmed.

Successful people—or those who can afford it—employ layers of other people whose job it is to narrow their own attentional filters.
