This week, as Judge Schroeder ruled on a motion by the prosecution, he also said that he would allow the terms “looters” and “rioters” to be used to refer to the men who were shot

The experts said the term “victim” can appear prejudicial in a court of law, heavily influencing a jury by presupposing which people have been wronged.

State law in Wisconsin allows a person to fire in self-defense if the shooter “reasonably believes that such force is necessary to prevent imminent death or great bodily harm to himself or herself.”Editors’ PicksTo Save a Swirling Season, Atlanta Turned to Soft ServeThink You Know the 1960s? ‘The Shattering’ Asks You to Think Again.

“In a self-defense case, the people who were shot are to some extent on trial,

Prosecutors have repeatedly tried to introduce evidence of Mr. Rittenhouse’s associations with the far-right Proud Boys, as well as a cellphone video taken weeks before the shootings in Kenosha in which Mr. Rittenhouse suggested that he wished he had his rifle so he could shoot men leaving a pharmacy. The judge did not allow either as evidence for trial.

Thomas Binger, a prosecutor, argued that the judge was creating a “double standard” and said that the words he sought to have prohibited — relating to rioting and other damage — were “as loaded, if not more loaded, than the term ‘victim.’

Conservatives thus embraced Hirsch eagerly and breathlessly. He was a stout defender of the patrimony. Liberals eagerly and breathlessly attacked him with equal vigor. He was retrograde, Eurocentric, racist, sexist.

Lost in all the crossfire, however, were two facts: First, Hirsch, a lifelong Democrat who considered himself progressive, believed his enterprise to be in service of social justice and equality. Cultural illiteracy, he argued, is most common among the poor and power-illiterate, and compounds both their poverty and powerlessness. Second: He was right.

A generation of hindsight now enables Americans to see that it is indeed necessary for a nation as far-flung and entropic as the United States, one where rising economic inequality begets worsening civic inequality, to cultivate continuously a shared cultural core. A vocabulary. A set of shared referents and symbols.

So, first of all, Americans do need a list. But second, it should not be Hirsch’s list. And third, it should not made the way he made his. In the balance of this essay, I want to unpack and explain each of those three statements.

If you take the time to read the book attached to Hirsch’s appendix, you’ll find a rather effective argument about the nature of background knowledge and public culture. Literacy is not just a matter of decoding the strings of letters that make up words or the meaning of each word in sequence. It is a matter of decoding context: the surrounding matrix of things referred to in the text and things implied by it

That means understanding what’s being said in public, in the media, in colloquial conversation. It means understanding what’s not being said. Literacy in the culture confers power, or at least access to power. Illiteracy, whether willful or unwitting, creates isolation from power.

his point about background knowledge and the content of shared public culture extends well beyond schoolbooks. They are applicable to the “texts” of everyday life, in commercial culture, in sports talk, in religious language, in politics. In all cases, people become literate in patterns—“schema” is the academic word Hirsch uses. They come to recognize bundles of concept and connotation like “Party of Lincoln.” They perceive those patterns of meaning the same way a chess master reads an in-game chessboard or the way a great baseball manager reads an at bat. And in all cases, pattern recognition requires literacy in particulars.

Lots and lots of particulars. This isn’t, or at least shouldn’t be, an ideologically controversial point. After all, parents on both left and right have come to accept recent research that shows that the more spoken words an infant or toddler hears, the more rapidly she will learn and advance in school. Volume and variety matter. And what is true about the vocabulary of spoken or written English is also true, one fractal scale up, about the vocabulary of American culture.

those who demonized Hirsch as a right-winger missed the point. Just because an endeavor requires fluency in the past does not make it worshipful of tradition or hostile to change.

radicalism is made more powerful when garbed in traditionalism. As Hirsch put it: “To be conservative in the means of communication is the road to effectiveness in modern life, in whatever direction one wishes to be effective.”

Hence, he argued, an education that in the name of progressivism disdains past forms, schema, concepts, figures, and symbols is an education that is in fact anti-progressive and “helps preserve the political and economic status quo.” This is true. And it is made more urgently true by the changes in American demography since Hirsch gave us his list in 1987.

If you are an immigrant to the United States—or, if you were born here but are the first in your family to go to college, and thus a socioeconomic new arrival; or, say, a black citizen in Ferguson, Missouri deciding for the first time to participate in a municipal election, and thus a civic neophyte—you have a single overriding objective shared by all immigrants at the moment of arrival: figure out how stuff really gets done here.

So, for instance, a statement like “One hundred and fifty years after Appomattox, our house remains deeply divided” assumes that the reader knows that Appomattox is both a place and an event; that the event signified the end of a war; that the war was the Civil War and had begun during the presidency of a man, Abraham Lincoln, who earlier had famously declared that “a house divided against itself cannot stand”; that the divisions then were in large part about slavery; and that the divisions today are over the political, social, and economic legacies of slavery and how or whether we are to respond to those legacies.

But why a list, one might ask? Aren’t lists just the very worst form of rote learning and standardized, mechanized education? Well, yes and no.

it’s not just newcomers who need greater command of common knowledge. People whose families have been here ten generations are often as ignorant about American traditions, mores, history, and idioms as someone “fresh off the boat.”

The more serious challenge, for Americans new and old, is to make a common culture that’s greater than the sum of our increasingly diverse parts. It’s not enough for the United States to be a neutral zone where a million little niches of identity might flourish; in order to make our diversity a true asset, Americans need those niches to be able to share a vocabulary. Americans need to be able to have a broad base of common knowledge so that diversity can be most fully activated.

as the pool of potential culture-makers has widened, the modes of culture creation have similarly shifted away from hierarchies and institutions to webs and networks. Wikipedia is the prime embodiment of this reality, both in how the online encyclopedia is crowd-created and how every crowd-created entry contains links to other entries.

so any endeavor that makes it easier for those who do not know the memes and themes of American civic life to attain them closes the opportunity gap. It is inherently progressive.

since I started writing this essay, dipping into the list has become a game my high-school-age daughter and I play together.

I’ll name each of those entries, she’ll describe what she thinks to be its meaning. If she doesn’t know, I’ll explain it and give some back story. If I don’t know, we’ll look it up together. This of course is not a good way for her teachers to teach the main content of American history or English. But it is definitely a good way for us both to supplement what school should be giving her.

And however long we end up playing this game, it is already teaching her a meta-lesson about the importance of cultural literacy. Now anytime a reference we’ve discussed comes up in the news or on TV or in dinner conversation, she can claim ownership. Sometimes she does so proudly, sometimes with a knowing look. My bet is that the satisfaction of that ownership, and the value of it, will compound as the years and her education progress.

The trouble is, there are also many items on Hirsch’s list that don’t seem particularly necessary for entry into today’s civic and economic mainstream.

Which brings us back to why diversity matters. The same diversity that makes it necessary to have and to sustain a unifying cultural core demands that Americans make the core less monochromatic, more inclusive, and continuously relevant for contemporary life

it’s worth unpacking the baseline assumption of both Hirsch’s original argument and the battles that erupted around it. The assumption was that multiculturalism sits in polar opposition to a traditional common culture, that the fight between multiculturalism and the common culture was zero-sum.

As scholars like Ronald Takaki made clear in books like A Different Mirror, the dichotomy made sense only to the extent that one imagined that nonwhite people had had no part in shaping America until they started speaking up in the second half of the twentieth century.

The truth, of course, is that since well before the formation of the United States, the United States has been shaped by nonwhites in its mores, political structures, aesthetics, slang, economic practices, cuisine, dress, song, and sensibility.

In its serious forms, multiculturalism never asserted that every racial group should have its own sealed and separate history or that each group’s history was equally salient to the formation of the American experience. It simply claimed that the omni-American story—of diversity and hybridity—was the legitimate American story.

as Nathan Glazer has put it (somewhat ruefully), “We are all multiculturalists now.” Americans have come to see—have chosen to see—that multiculturalism is not at odds with a single common culture; it is a single common culture.

it is true that in a finite school year, say, with finite class time and books of finite heft, not everything about everyone can be taught. There are necessary trade-offs. But in practice, recognizing the true and longstanding diversity of American identity is not an either-or. Learning about the internment of Japanese Americans does not block out knowledge of D-Day or Midway. It is additive.

As more diverse voices attain ever more forms of reach and power we need to re-integrate and reimagine Hirsch’s list of what literate Americans ought to know.

To be clear: A 21st-century omni-American approach to cultural literacy is not about crowding out “real” history with the perishable stuff of contemporary life. It’s about drawing lines of descent from the old forms of cultural expression, however formal, to their progeny, however colloquial.

Nor is Omni-American cultural literacy about raising the “self-esteem” of the poor, nonwhite, and marginalized. It’s about raising the collective knowledge of all—and recognizing that the wealthy, white, and powerful also have blind spots and swaths of ignorance

What, then, would be on your list? It’s not an idle question. It turns out to be the key to rethinking how a list should even get made.

the Internet has transformed who makes culture and how. As barriers to culture creation have fallen, orders of magnitude more citizens—amateurs—are able to shape the culture in which we must all be literate. Cat videos and Star Trek fan fiction may not hold up long beside Toni Morrison. But the entry of new creators leads to new claims of right: The right to be recognized. The right to be counted. The right to make the means of recognition and accounting.

It is true that lists alone, with no teaching to bring them to life and no expectation that they be connected to a broader education, are somewhere between useless and harmful.

This will be a list of nodes and nested networks. It will be a fractal of associations, which reflects far more than a linear list how our brains work and how we learn and create. Hirsch himself nodded to this reality in Cultural Literacy when he described the process he and his colleagues used for collecting items for their list, though he raised it by way of pointing out the danger of infinite regress.

His conclusion, appropriate to his times, was that you had to draw boundaries somewhere with the help of experts. My take, appropriate to our times, is that Americans can draw not boundaries so much as circles and linkages, concept sets and pathways among them.

Because 5,000 or even 500 items is too daunting a place to start, I ask here only for your top ten. What are ten things every American—newcomer or native born, affluent or indigent—should know? What ten things do you feel are both required knowledge and illuminating gateways to those unenlightened about American life? Here are my entries: Whiteness The Federalist Papers The Almighty Dollar Organized labor Reconstruction Nativism The American Dream The Reagan Revolution DARPA A sucker born every minute

Jean-Benoît Nadeau, a Canadian who co-wrote a forthcoming book on French conversation, told me that the penchant for saying “no” or “it’s not possible” is often a cover for the potential humiliation of seeming not to know something. Only once you trust someone can you turn down the wit and reveal your weaknesses

At least it’s not boring. Even among friends, being dull is almost criminal. A French entrepreneur told me her rules for dinner-party topics: no kids, no jobs, no real estate. Provocative opinions are practically required. “You must be a little bit mean but also a little bit vulnerable,” she said.

It’s dizzying to switch to the British conversational mode, in which everyone’s trying to show they don’t take themselves seriously. The result is lots of self-deprecation and ironic banter. I’ve sat through two-hour lunches in London waiting for everyone to stop exchanging quips so the real conversation could begin. But “real things aren’t supposed to come up,” my husband said. “Banter can be the only mode of conversation you ever have with someone.”

Earnestness makes British people gag

After being besieged by British irony and French wit, I sometimes yearn for the familiar comfort of American conversations, where there are no stupid questions. Among friends, I merely have to provide reassurance and mirroring: No, you don’t look fat, and anyway, I look worse.

It might not matter what I say, since some American conversations resemble a succession of monologues. A 2014 study led by a psychologist at Yeshiva University found that when researchers crossed two unrelated instant-message conversations, as many as 42 percent of participants didn’t notice

A lot of us — myself included — could benefit from a basic rule of improvisational comedy: Instead of planning your next remark, just listen very hard to what the other person is saying. Call it “mindful conversation,” if you like. That’s what the French tend to do

I don’t know if that sounds too complicated. But the point is, it’s not just giving up domination. It’s giving up this sense of separateness in favor of a sense of kinship. And those people who do often wonder how they failed to see how much continuity there is in the more-than-human world with the human world.

to go from terror into being and into that sense that the experiment is sacred, not this one outcome of the experiment, is to immediately transform the way that you think even about very fundamental social and economic and cultural things. If the experiment is sacred, how can we possibly justify our food systems, for instance?

when I first went to the Smokies and hiked up into the old growth in the Southern Appalachians, it was like somebody threw a switch. There was some odd filter that had just been removed, and the world sounded different and smelled different.

richard powersYeah. In human exceptionalism, we may be completely aware of evolutionary continuity. We may understand that we have a literal kinship with the rest of creation, that all life on Earth employs the same genetic code, that there is a very small core of core genes and core proteins that is shared across all the kingdoms and phyla of life. But conceptually, we still have this demented idea that somehow consciousness creates a sanctity and a separation that almost nullifies the continuous elements of evolution and biology that we’ve come to understand.

if we want to begin this process of rehabilitation and transformation of consciousness that we are going to need in order to become part of the living Earth, it is going to be other kinds of minds that give us that clarity and strength and diversity and alternative way of thinking that could free us from this stranglehold of thought that looks only to the maximizing return on investment in very leverageable ways.

richard powersIt amazed me to get to the end of the first draft of “Bewilderment” and to realize how much Buddhism was in the book, from the simplest things.

I think there is nothing more science inflected than being out in the living world and the more-than-human world and trying to understand what’s happening.

And of course, we can combine this with what we were talking about earlier with death. If we see all of evolution as somehow leading up to us, all of human, cultural evolution leading up to neoliberalism and here we are just busily trying to accumulate and make meaning for ourselves, death becomes the enemy.

And you’re making the point in different ways throughout the book that it is the minds we think of as unusual, that we would diagnose as having some kind of problem or dysfunction that are, in some cases, are the only ones responding to the moment in the most common sense way it deserves. It is almost everybody else’s brain that has been broken.

it isn’t surprising. If you think of the characteristics of this dominant culture that we’ve been talking about — the fixation on control, the fixation on mastery, the fixation on management and accumulation and the resistance of decay — it isn’t surprising that that culture is also threatened by difference and divergence. It seeks out old, stable hierarchies — clear hierarchies — of control, and anything that’s not quite exploitable or leverageable in the way that the normal is terrifying and threatening.

And the more I looked for it, the more it pervaded the book.

ezra kleinI’ve heard you say that it has changed the way you measure a good day. Can you tell me about that?richard powersThat’s true.I suppose when I was still enthralled to commodity-mediated individualist market-driven human exceptionalism — we need a single word for this

And since moving to the Smokies and since publishing “The Overstory,” my days have been entirely inverted. I wake up, I go to the window, and I look outside. Or I step out onto the deck — if I haven’t been sleeping on the deck, which I try to do as much as I can in the course of the year — and see what’s in the air, gauge the temperature and the humidity and the wind and see what season it is and ask myself, you know, what’s happening out there now at 1,700 feet or 4,000 feet or 5,000 feet.

let me talk specifically about the work of a scientist who has herself just recently published a book. It’s Dr. Suzanne Simard, and the book is “Finding the Mother Tree.” Simard has been instrumental in a revolution in our way of thinking about what’s happening underground at the root level in a forest.

it was a moving moment for me, as an easterner, to stand up there and to say, this is what an eastern forest looks like. This is what a healthy, fully-functioning forest looks like. And I’m 56 years old, and I’d never seen it.

the other topics of that culture tend to circle back around these sorts of trends, human fascinations, ways of magnifying our throw weight and our ability and removing the last constraints to our desires and, in particular, to eliminate the single greatest enemy of meaning in the culture of the technological sublime that is, itself, such a strong instance of the culture of human separatism and commodity-mediated individualist capitalism— that is to say, the removal of death.

Why is it that we have known about the crisis of species extinction for at least half a century and longer? And I mean the lay public, not just scientists. But why has this been general knowledge for a long time without public will demanding some kind of action or change

And when you make kinship beyond yourself, your sense of meaning gravitates outwards into that reciprocal relationship, into that interdependence. And you know, it’s a little bit like scales falling off your eyes. When you do turn that corner, all of the sources of anxiety that are so present and so deeply internalized become much more identifiable. And my own sense of hope and fear gets a much larger frame of reference to operate in.

I think, for most of my life, until I did kind of wake up to forests and to trees, I shared — without really understanding this as a kind of concession or a kind of subscription — I did share this cultural consensus that meaning is a private thing that we do for ourselves and by ourselves and that our kind of general sense of the discoveries of the 19th and 20th century have left us feeling a bit unsponsored and adrift beyond the accident of human existence.

The largest single influence on any human being’s mode of thought is other human beings. So if you are surrounded by lots of terrified but wishful-thinking people who want to believe that somehow the cavalry is going to come at the last minute and that we don’t really have to look inwards and change our belief in where meaning comes from, that we will somehow be able to get over the finish line with all our stuff and that we’ll avert this disaster, as we have other kinds of disasters in the past.

I think what was happening to me at that time, as I was turning outward and starting to take the non-human world seriously, is my sense of meaning was shifting from something that was entirely about me and authored by me outward into this more collaborative, reciprocal, interdependent, exterior place that involved not just me but all of these other ways of being that I could make kinship with.

And I think I was right along with that sense that somehow we are a thing apart. We can make purpose and make meaning completely arbitrarily. It consists mostly of trying to be more in yourself, of accumulating in one form or another.

I can’t really be out for more than two or three miles before my head just fills with associations and ideas and scenes and character sketches. And I usually have to rush back home to keep it all in my head long enough to get it down on paper.

for my journey, the way to characterize this transition is from being fascinated with technologies of mastery and control and what they’re doing to us as human beings, how they’re changing what the capacities and affordances of humanity are and how we narrate ourselves, to being fascinated with technologies and sciences of interdependence and cooperation, of those sciences that increase our sense of kinship and being one of many, many neighbors.

And that’s an almost impossible persuasion to rouse yourself from if you don’t have allies. And I think the one hopeful thing about the present is the number of people trying to challenge that consensual understanding and break away into a new way of looking at human standing is growing.

And when you do subscribe to a culture like that and you are confronted with the reality of your own mortality, as I was when I was living in Stanford, that sense of stockpiling personal meaning starts to feel a little bit pointless.

And I just head out. I head out based on what the day has to offer. And to have that come first has really changed not only how I write, but what I’ve been writing. And I think it really shows in “Bewilderment.” It’s a totally different kind of book from my previous 12.

the marvelous thing about the work, which continues to get more sophisticated and continues to turn up newer and newer astonishments, is that there was odd kind of reciprocal interdependence and cooperation across the species barrier, that Douglas firs and birches were actually involved in these sharing back and forth of essential nutrients. And that’s a whole new way of looking at forest.

she began to see that the forests were actually wired up in very complex and identifiable ways and that there was an enormous system of resource sharing going on underground, that trees were sharing not only sugars and the hydrocarbons necessary for survival, but also secondary metabolites. And these were being passed back and forth, both symbiotically between the trees and the fungi, but also across the network to other trees so that there were actually trees in wired up, fungally-connected forests where large, dominant, healthy trees were subsidizing, as it were, trees that were injured or not in favorable positions or damaged in some way or just failing to thrive.

so when I was still pretty much a card-carrying member of that culture, I had this sense that to become a better person and to get ahead and to really make more of myself, I had to be as productive as possible. And that meant waking up every morning and getting 1,000 words that I was proud of. And it’s interesting that I would even settle on a quantitative target. That’s very typical for that kind of mindset that I’m talking about — 1,000 words and then you’re free, and then you can do what you want with the day.

there will be a threshold, as there have been for these other great social transformations that we’ve witnessed in the last couple of decades where somehow it goes from an outsider position to absolutely mainstream and common sense.

I am persuaded by those scholars who have showed the degree to which the concept of nature is itself an artificial construction that’s born of cultures of human separatism. I believe that everything that life does is part of the living enterprise, and that includes the construction of cities. And there is no question at all the warning that you just gave about nostalgia creating a false binary between the built world and the true natural world is itself a form of cultural isolation.

Religion is a technology to discipline, to discipline certain parts of the human impulse. A lot of the book revolves around the decoded neurofeedback machine, which is a very real literalization of a technology, of changing the way we think

one of the things I think that we have to take seriously is that we have created technologies to supercharge some parts of our natural impulse, the capitalism I think should be understood as a technology to supercharge the growth impulse, and it creates some wonders out of that and some horrors out of that.

richard powersSure. I base my machine on existing technology. Decoded neurofeedback is a kind of nascent field of exploration. You can read about it; it’s been publishing results for a decade. I first came across it in 2013. It involves using fMRI to record the brain activity of a human being who is learning a process, interacting with an object or engaged in a certain emotional state. That neural activity is recorded and stored as a data structure. A second subsequent human being is then also scanned in real time and fed kinds of feedback based on their own internal neural activity as determined by a kind of software analysis of their fMRI data structures.

And they are queued little by little to approximate, to learn how to approximate, the recorded states of the original subject. When I first read about this, I did get a little bit of a revelation. I did feel my skin pucker and think, if pushed far enough, this would be something like a telepathy conduit. It would be a first big step in answering that age-old question of what does it feel like to be something other than we are

in the book I simply take that basic concept and extend it, juke it up a little bit, blur the line between what the reader might think is possible right now and what they might wonder about, and maybe even introduce possibilities for this empathetic transference

ezra kleinOne thing I loved about the role this played in the book is that it’s highlighting its inverse. So a reader might look at this and say, wow, wouldn’t that be cool if we had a machine that could in real time change how we think and change our neural pathways and change our mental state in a particular direction? But of course, all of society is that machine,

Robin and Theo are in an airport. And you’ve got TVs everywhere playing the news which is to say playing a constant loop of outrage, and disaster, and calamity. And Robbie, who’s going through these neural feedback sessions during this period, turns to his dad and says, “Dad, you know how the training’s rewiring my brain? This is what is rewiring everybody else.”

ezra kleinI think Marshall McLuhan knew it all. I really do. Not exactly what it would look like, but his view and Postman’s view that we are creating a digital global nervous system is a way they put it, it was exactly right. A nervous system, it was such the exact right metaphor.

the great insight of McLuhan, to me, what now gets called the medium is the message is this idea that the way media acts upon us is not in the content it delivers. The point of Twitter is not the link that you click or even the tweet that you read; it is that the nature and structure of the Twitter system itself begins to act on your system, and you become more like it.If you watch a lot of TV, you become more like TV. If you watch a lot of Twitter, you become more like Twitter, Facebook more like Facebook. Your identities become more important to you — that the content is distraction from the medium, and the medium changes you

it is happening to all of us in ways that at least we are not engaging in intentionally, not at that level of how do we want to be transformed.

richard powersI believe that the digital neural system is now so comprehensive that the idea that you could escape it somewhere, certainly not in the Smokies, even more remotely, I think, becomes more and more laughable. Yeah, and to build on this idea of the medium being the message, not the way in which we become more like the forms and affordances of the medium is that we begin to expect that those affordances, the method in which those media are used, the physiological dependencies and castes of behavior and thought that are required to operate them and interact with them are actual — that they’re real somehow, and that we just take them into human nature and say no, this is what we’ve always wanted and we’ve simply been able to become more like our true selves.

Well, the warpage in our sense of time, the warpage in our sense of place, are profound. The ways in which digital feedback and the affordances of social media and all the rest have changed our expectations with regard to what we need to concentrate on, what we need to learn for ourselves, are changing profoundly.

If you look far enough back, you can find Socrates expressing great anxiety and suspicion about the ways in which writing is going to transform the human brain and human expectation. He was worried that somehow it was going to ruin our memories. Well, it did up to a point — nothing like the way the digital technologies have ruined our memories.

my tradition is Jewish, the Sabbath is a technology, is a technology to create a different relationship between the human being, and time, and growth, and productive society than you would have without the Sabbath which is framed in terms of godliness but is also a way of creating separation from the other impulses of the weak.

Governments are a technology, monogamy is a technology, a religiously driven technology, but now one that is culturally driven. And these things do good and they do bad. I’m not making an argument for any one of them in particular. But the idea that we would need to invent something wholly new to come up with a way to change the way human beings act is ridiculous

My view of the story of this era is that capitalism was one of many forces, and it has become, in many societies, functionally the only one that it was in relationship with religion, it was in relationship with more rooted communities.

it has become not just an economic system but a belief system, and it’s a little bit untrammeled. I’m not an anti-capitalist person, but I believe it needs countervailing forces. And my basic view is that it doesn’t have them anymore.

the book does introduce this kind of fable, this kind of thought experiment about the way the affordances that a new and slightly stronger technology of empathy might deflect. First of all, the story of a little boy and then the story of his father who’s scrambling to be a responsible single parent. And then, beyond that, the community of people who hear about this boy and become fascinated with him as a narrative, which again ripples outward through these digital technologies in ways that can’t be controlled or whose consequences can be foreseen.

I’ve talked about it before is something I’ve said is that I think a push against, functionally, materialism and want is an important weight in our society that we need. And when people say it is the way we’ll deal with climate change in the three to five year time frame, I become much more skeptical because to the point of things like the technology you have in the book with neural feedback, I do think one of the questions you have to ask is, socially and culturally, how do you move people’s minds so you can then move their politics?

You’re going to need something, it seems to me, outside of politics, that changes humans’ sense of themselves more fundamentally. And that takes a minute at the scale of billions.

richard powersWell, you are correct. And I don’t think it’s giving away any great reveal in the book to say that a reader who gets far enough into the story probably has this moment of recursive awareness where they, he or she comes to understand that what Robin is doing in this gradual training on the cast of mind of some other person is precisely what they’re doing in the act of reading the novel “Bewilderment” — by living this act of active empathy for these two characters, they are undergoing their own kind of neurofeedback.

The more we understand about the complexities of living systems, of organisms and the evolution of organisms, the more capable it is to feel a kind of spiritual awe. And that certainly makes it easier to have reverence for the experiment beyond me and beyond my species. I don’t think those are incommensurable or incompatible ways of knowing the world. In fact, I think to invoke one last time that Buddhist precept of interbeing, I think there is a kind of interbeing between the desire, the true selfless desire to understand the world out there through presence, care, measurement, attention, reproduction of experiment and the desire to have a spiritual affinity and shared fate with the world out there. They’re really the same project.

richard powersWell, sure. If we turn back to the new forestry again and researchers like Suzanne Simard who were showing the literal interconnectivity across species boundaries and the cooperation of resource sharing between different species in a forest, that is rigorous science, rigorous reproducible science. And it does participate in that central principle of practice, or collection of practices, which always requires the renunciation of personal wish and ego and prior belief in favor of empirical reproduction.

I’ve begun to see people beginning to build out of the humbling sciences a worldview that seems quite spiritual. And as you’re somebody who seems to me to have done that and it has changed your life, would you reflect on that a bit?

So much of the book is about the possibility of life beyond Earth. Tell me a bit about the role that’s playing. Why did you make the possibility of alien life in the way it might look and feel and evolve and act so central in a book about protecting and cherishing life here?

richard powersI’m glad that we’re slipping this in at the end because yes this framing of the book around this question of are we alone or does the universe want life it’s really important. Theo, Robin’s father, is an astrobiologist.

Imagine that everything happens just right so that every square inch of this place is colonized by new forms of experiments, new kinds of life. And the father trying to entertain his son with the story of this remarkable place in the sun just stopping him and saying, Dad, come on, that’s asking too much. Get real, that’s science fiction. That’s the vision that I had when I finished the book, an absolutely limitless sense of just how lucky we’ve had it here.

one thing I kept thinking about that didn’t make it into the final book but exists as a kind of parallel story in my own head is the father and son on some very distant planet in some very distant star, many light years from here, playing that same game. And the father saying, OK, now imagine a world that’s just the right size, and it has plate tectonics, and it has water, and it has a nearby moon to stabilize its rotation, and it has incredible security and safety from asteroids because of other large planets in the solar system.

they make this journey across the universe through all kinds of incubators, all kinds of petri dishes for life and the possibilities of life. And rather than answer the question — so where is everybody? — it keeps deferring the question, it keeps making that question more subtle and stranger

For the purposes of the book, Robin, who desperately believes in the sanctity of life beyond himself, begs his father for these nighttime, bedtime stories, and Theo gives him easy travel to other planets. Father and son going to a new planet based on the kinds of planets that Theo’s science is turning up and asking this question, what would life look like if it was able to get started here?

Quadriplegics like Scheuermann have manipulated robotic arms using BCI before.

"With three degrees of control, you can do things like manipulate a computer screen and that gentleman was able to reach out and touch his daughter

But to actually manipulate objects, to feed yourself for example, you need more than those three dimensions of control. That's what makes Jan so remarkable

"The biggest change," Boninger said, "is the sophistication with which we've learned to interpret electrical activity in the brain."

"I wouldn't say we have decoded the brain," Boninger said. "But we are getting closer. We can't read emotions but we can interpret motions the brain wants the body to make."

"For me, it's been one of the most exciting endeavors I have ever undertaken," Sheuermann wrote on the University of Pittsburgh Medical Center blog. "Being with a team of scientists and using cutting-edge technology that makes me the only person in the world who can scratch her nose with a robotic arm, well, that's thrilling."

The effectiveness of this process is so great that human brain is able to accurately identify words and whole phrases from a noisy background. This power of analysis brings to minds the great similarity between the brain and powerful supercomputers.

Functional imaging of the brain revealed that activated brain parts are different between native and non-native speakers. The superior temporal gyrus is an important brain region involved in language learning. For a native speaker this part is responsible for automated processing of lexical retrieval and the build of phrase structure. In native speakers this zone is much more activated than in non-native ones.

infants begin their lives with a very flexible brain that allows them to acquire virtually any language they are exposed to. Moreover, they can learn a language words almost equally by listening or by visual coding. This brain plasticity is the motor drive of the children capability of “cracking the speech code” of a language. With time, this ability is dramatically decreased and adults find it harder to acquire a new language.

clearly demonstrated that there are anatomical brain differences between fast and slow learners of foreign languages. By analyzing a group of people having a homogenous language background, scientists found that differences in specific brain regions can predict the capacity of a person to learn a second language.

Until the last decade few studies compared the language acquisition in adults and children. Thanks to modern imaging and electroencephalography we are now able to address this question.

Language acquisition is a long-term process by which information are stored in the brain unconsciously making them appropriate to oral and written usage. In contrast, language learning is a conscious process of knowledge acquisition that needs supervision and control by the person.

Do babies’ brains work like miniature versions of adult brains, or are they completely different?

We’re only beginning to understand how babies’ brains are organized; it will require many more hours collecting data from a larger number of babies to have a fuller picture of how their brains work. But Saxe and her colleagues have shown that such a study can be done, which opens up new areas of investigation. “It is possible to get good fMRI data in awake babies—if you are extremely patient,” Saxe said. “Now let’s try to figure out what we can learn from it.”

If a brain can make crazy leaps across the cosmos and bring extra passengers along (like you when you listen to me), then in a metaphorical way, the brain is bigger than what's around it, wrote 19th century poet Emily Dickinson. The brain is wider than the sky,For, put them side by side,The one the other will includeWith ease, and you beside.

"The universe is not only queerer than we suppose," said the biologist J.B.S. Haldane, "but queerer than we can suppose." In Haldane's view, the universe is bigger than the brain. There are things we just can't know, or even conjure with the brains we've got.

There are philosophers and scientists who say we will never understand the universe, we can't fathom the endless details or make good sense of the whole. We can try, but the universe is too big. The writer John Updike once explained the argument this way to reporter Jim Holt: "It's beyond our intellectual limits as a species. Put yourself into the position of a dog. A dog is responsive, shows intuition, looks at us with eyes behind which there is intelligence of a sort, and yet a dog must not understand most of the things it sees people doing. It must have no idea how they invented, say, the internal combustion engine. So maybe what we need to do is imagine that we're dogs and that there are realms that go beyond our understanding."

So does the universe get the crown?

Carl Sagan thought that we humans are good at finding patterns in nature, and if we know the rules, we can skip the details and understand the outline, the essence. It's not necessary for us to know everything. The problem is we don't know how many rules the cosmos has.

et the brain has its champions. "Consider the human brain," says physicist Sir Roger Penrose. "If you look at the entire physical cosmos, our brains are a tiny, tiny part of it. But they're the most perfectly organized part. Compared to the complexity of a brain, a galaxy is just an inert lump

my hunch is the universe will still outwit us, will still be "too wonderful" to be decoded, because we are, in the end, so much smaller than it is. And that's not a bad thing. To my mind, it's the search that matters, that sharpens us, gives us something noble to do.

Steven Weinberg famously said, "The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy."

imagine that in the future scientists will be able to map and decode all your mental states with arbitrary precision. They could then predict what you will do before you are aware of your choice.

the experiments in question here are limited to decisions that are far removed from the truly complex choices we make in our lives, those that involve a lot of back and forth thinking, prompt confusion, result in pondering, require talking to other people and generally take time to arrive at a conclusion

When it comes to the choices we make in life, there is a spectrum of complexity and this is reflected in the issue of free will. Some do indeed happen before conscious awareness, and others don't.

On Tinder, there are no questionnaires to fill out. No discussion of your favorite hiking trail, star sign or sexual proclivities. You simply log in through Facebook, pick a few photos that best describe “you” and start swiping.It may seem that what happens next is predictable (the best-looking people draw the most likes, the rest are quickly dismissed), but relationships experts for Tinder say there is something entirely different going on.

“Research shows when people are evaluating photos of others, they are trying to access compatibility on not just a physical level, but a social level,” said Jessica Carbino, Tinder’s in-house dating and relationship expert. “They are trying to understand, ‘Do I have things in common with this person?' ”

She discovered that Tinder users decoded an array of subtle and not-so-subtle traits before deciding which way to swipe. For example, the style of clothing, the pucker of the lips and even the posture, Ms. Carbino said, tell us a lot about their social circle, if they like to party and their level of confidence.

Men also judge attractiveness on factors beyond just anatomy, though in general, men are nearly three times as likely to swipe “like” (in 46 percent of cases) than woman (14 percent).

Mr. Finkel worked for more than a year with a group of researchers trying to understand how these algorithm-based dating services could match people, as they claim to do. The team poured through more than 80 years of scientific research about dating and attraction, and was unable to prove that computers can indeed match people together.

while computers have become incalculably smarter, the ability of machines and algorithms to match people has remained just as clueless in the view of independent scientists.

dating sites like eHarmony and Match.com are more like modern snake oil. “They are a joke, and there is no relationship scientist that takes them seriously as relationship science.”

“There is this idea that attraction stems from a very superficial outlook on people, which is false,” Mr. Rad said. “Everyone is able to pick up thousands of signals in these photos. A photo of a guy at a bar with friends around him sends a very different message than a photo of a guy with a dog on the beach.”

some dating sites are starting to acknowledge that the only thing that matters when matching lovers is someone’s picture. Earlier this year, OKCupid examined its data and found that a person’s profile picture is, said a post on its Oktrends blog, “worth that fabled thousand words, but your actual words are worth... almost nothing.”

this doesn’t mean that the most attractive people are the only ones who find true love. Indeed, in many respects, it can be the other way around.

a graduate student, published a paper noting that a person’s unique looks are what is most important when trying to find a mate.

“There isn’t a consensus about who is attractive and who isn’t,” Mr. Eastwick said in an interview. “Someone that you think is especially attractive might not be to me. That’s true with photos, too.” Tinder’s data team echoed this, noting that there isn’t a cliquey, high school mentality on the site, where one group of users get the share of “like” swipes.

if one person can think he’s hooking up while the other feels she’s being raped, it makes sense to have a law that eliminates the possibility of misunderstanding. “You shouldn’t be allowed to make the assumption that if you find someone lying on a bed, they’re free for sexual pleasure,”

About a quarter of all states, and the District of Columbia, now say sex isn’t legal without positive agreement,

And though most people think of “yes means yes” as strictly for college students, it is actually poised to become the law of the land.

But criminal law is a very powerful instrument for reshaping sexual mores.

Should we really put people in jail for not doing what most people aren’t doing? (Or at least, not yet?)

It’s one thing to teach college students to talk frankly about sex and not to have it without demonstrable pre-coital assent. Colleges are entitled to uphold their own standards of comportment, even if enforcement of that behavior is spotty or indifferent to the rights of the accused. It’s another thing to make sex a crime under conditions of poor communication.

Most people just aren’t very talkative during the delicate tango that precedes sex, and the re-education required to make them more forthcoming would be a very big project. Nor are people unerringly good at decoding sexual signals. If they were, we wouldn’t have romantic comedies.

“If there’s no social consensus about what the lines are,” says Nancy Gertner, a senior lecturer at Harvard Law School and a retired judge, then affirmative consent “has no business being in the criminal law.”

The example points to a trend evident both on campuses and in courts: the criminalization of what we think of as ordinary sex and of sex previously considered unsavory but not illegal.

Some new crimes outlined in the proposed code, for example, assume consent to be meaningless under conditions of unequal power. Consensual sex between professionals (therapists, lawyers and the like) and their patients and clients, for instance, would be a fourth-degree felony, punishable by significant time in prison.

most of these occupations already have codes of professional conduct, and victims also have recourse in the civil courts. Miscreants, she says, “should be drummed out of the profession or sued for malpractice.”

It’s important to remember that people convicted of sex crimes may not only go to jail, they can wind up on a sex-offender registry, with dire and lasting consequences.

We shouldn’t forget the harm done to American communities by the national passion for incarceration, either. In a letter to the American Law Institute, Ms. Smith listed several disturbing statistics: roughly one person in 100 behind bars, one in 31 under correctional supervision

the case for affirmative consent is “compelling,” he says. Mr. Schulhofer has argued that being raped is much worse than having to endure that awkward moment when one stops to confirm that one’s partner is happy to continue. Silence or inertia, often interpreted as agreement, may actually reflect confusion, drunkenness or “frozen fright,” a documented physiological response in which a person under sexual threat is paralyzed by terror

To critics who object that millions of people are having sex without getting unqualified assent and aren’t likely to change their ways, he’d reply that millions of people drive 65 miles per hour despite a 55-mile-per-hour speed limit, but the law still saves lives. As long as “people know what the rules of the road are,” he says, “the overwhelming majority will comply with them.”

He understands that the law will have to bring a light touch to the refashioning of sexual norms, which is why the current draft of the model code suggests classifying penetration without consent as a misdemeanor, a much lesser crime than a felony.

This may all sound reasonable, but even a misdemeanor conviction goes on the record as a sexual offense and can lead to registration

An affirmative consent standard also shifts the burden of proof from the accuser to the accused, which represents a real departure from the traditions of criminal law in the United States. Affirmative consent effectively means that the accused has to show that he got the go-ahead

if the law requires a “no,” then the jury will likely perceive any uncertainty about that “no” as a weakness in the prosecution’s case and not convict. But if the law requires a “yes,” then ambiguity will bolster the prosecutor’s argument: The guy didn’t get unequivocal consent, therefore he must be guilty of rape.

“It’s an unworkable standard,” says the Harvard law professor Jeannie C. Suk. “It’s only workable if we assume it’s not going to be enforced, by and large.” But that’s worrisome too. Selectively enforced laws have a nasty history of being used to harass people deemed to be undesirable, because of their politics, race or other reasons.

it’s probably just a matter of time before “yes means yes” becomes the law in most states. Ms. Suk told me that she and her colleagues have noticed a generational divide between them and their students. As undergraduates, they’re learning affirmative consent in their mandatory sexual-respect training sessions, and they come to “believe that this really is the best way to define consent, as positive agreement,” she says. When they graduate and enter the legal profession, they’ll probably reshape the law to reflect that belief.

Sex may become safer for some, but it will be a whole lot more anxiety-producing for others.

six to ten months children have already learned to be sensitive to the basic sounds, known as phonemes, that matter in their native language.

language requires real-time mappings between words and their meanings. This requires that the sounds heard in speech – decoded in the auditory cortex – must be integrated with knowledge about what they mean – in the frontal cortex.

Modern theories on connectionism – the idea that knowledge is distributed across different parts of the brain and not tucked into dedicated modules like Broca’s area – have compelled researchers to take a closer look.

found that these differences between Mandarin Chinese and English change the way the brain’s networks work.

non-tonal language such as English, tone might convey emotional information about the speaker, but indicates nothing about the meaning of the word that is spoken

Mandarin Chinese is a tonal language in which the same basic sounds can refer to vastly different things based on the tone with which it is spoken

researchers took advantage of the basic differences between Mandarin Chinese and English to investigate the differences between the language networks of native speakers of tonal and non-tonal languages. Thirty native Chinese speakers were matched on age, gender, and handedness (they were all right-handed) with a sample of native English speakers. All participants listened to intelligible and unintelligible speech and were asked to judge the gender of the speaker.

The first difference was the operation of the brain networks shared by English and Chinese speakers

English speakers showed stronger connectivity leading from Wernicke’s area to Broca’s area. This increased connectivity was attributed to English relying more heavily on phonological information, or sounds rather than tones.

Chinese speakers had stronger connections leading from an area of the brain called the anterior superior temporal gyrus – which has been identified as a “semantic hub” critical in supporting language – to both Broca’s and Wernicke’s area.

increased connectivity is attributed to the enhanced mapping of sound and meaning going on in people who speak tonal languages.

second difference showed activation in an area of the brain’s right hemisphere, but only among the Chinese speakers

findings emphasise the importance of developing a bilateral network between the two brain hemispheres to speak and understand languages, particularly for tonal languages like Mandarin Chinese.

Most people successfully avoided reading until about 300 years ago. It was about then that Western European priests and princes decided that everyone should be taught to read. These literacy-loving types tried various schemes to make common folks literate; the most effective of these, however, was naked coercion. By the nineteenth century, churches and states all over Europe and North America were forcing parents to send their kids to school to learn to read

So it happened that by the early twentieth century most people in Western Europe and North America could read. They had no choice in the matter. They still don’t.

Why don’t most people like to read? The answer is surprisingly simple: humans weren’t evolved to read. Note that we have no reading organs: our eyes and brains were made for watching, not for decoding tiny symbols on mulch sheets. To prepare our eyes and brains for reading, we must rewire them. This process takes years of hard work to accomplish, and some people never accomplish it all. Moreover, even after you’ve learned to read, you probably won’t find reading to be very much fun. It consumes all of your attention, requires active thought, and makes your eyes hurt. For most people, then, reading is naturally hard and, therefore, something to be avoided if at all possible.

we have misidentified the “problem” facing us: it is not the much-bemoaned reading gap, but rather a seldom-mentioned knowledge gap. Though it is immodest to say, we readers genuinely know more than those who do not read. Thus we are usually able to make better-informed decisions than non-readers can.

If we lived in an aristocracy of readers, this maldistribution of knowledge might be acceptable. But we don’t; rather, we live in a democracy (if we are lucky). In a democracy, the people – readers and non-readers alike – decide. Thus we would like all citizens to be knowledgeable so that they can make well-informed decisions about our common affairs. This has been a central goal of the Reading Class since the literacy-loving Enlightenment.

If we in the Reading Class want to teach the the reading-averse public more effectively than we have in the past, we must rid ourselves of our reading fetish and admit that we’ve been falling down on the job. Once we take this painful step, then a number of interesting options for closing the knowledge gap become available. The most promising of these options is using audio and video to share what we know with the public at large.

We have to laboriously learn to read, but we are born with the ability to watch and listen. We don’t find reading terribly pleasant, but we do find watching and listening generally enjoyable.

The results of this “natural experiment” are in: people would much rather watch/listen than read. This is why Americans sit in front of the television for three hours a day, while they read for only a tiny fraction of that time.

Our task, then, is to give them something serious to watch and listen to, something that conveys the richness and complexity of our written work in pictures and sounds. The good news is that we can easily do this.

Today any lecturer can produce and distribute high quality audio and video programs. Most scholars have the equipment on their desks (that is, a PC). The software is dead simple and inexpensive. And the shows themselves can be distributed the world over on the Internet for almost nothing.

I’ve done it. Here are two examples. The first is New Books in History, an author-interview podcast featuring historians with new books. Aside from the computer, the total hardware and software start-up costs were roughly $300. It took me no time to learn the software thanks to some handy on-line tutorials available on Lynda.com. Today New Books in History has a large international audience.

The “new books” podcasts are not about serious books; they are about the ideas trapped in those serious, and seriously un-read, books. Books imprison ideas; the “new books” podcasts set them free.)

Of the 27 artists recognized, 20 were born in the U.S

most of these artists haven’t captured or maybe even appealed to a mass audience

Most of the artists have adopted a similar pose: political provocateur. The works are less beautiful creations to be experienced and more often political statements to be decoded

What you see when all these works are brought together is how the aesthetic has given way to the political, how the inner life has given way to the protest gesture.

Among these 25 pieces, 20 are impersonal and only five allow you to see what life is like for another human being

Only a few explore relationships and emotional connection.

There almost seems to be a taboo now against capturing states like joy, temptation, gratitude, exaltation, betrayal, forgiveness and longing.

one of the things art has traditionally done is educate the emotions

Lisa Feldman Barrett and other neuroscientists argue that emotions aren’t baked into our nature as things all humans share. They are constructed by culture — art and music, and relationships.

When we see the depth of psychological expression in a Rembrandt portrait, or experience the intimacy of a mother and daughter in a Mary Cassatt, we’re not gaining a new fact, but we’re experiencing a new emotion. We’re widening the repertoire of ways we can feel and can communicate feelings to others.

Barrett uses the phrase “emotional granularity” to capture the reality that some people — and some eras — experience a wider range and specificity of emotions than others.

People with highly educated emotions can be astonished by the complexity of other people without feeling the need to judge them immediately as good or bad according to some political logic.

continued building in high-risk areas had also contributed to the growing losses.Image

Topping the list was Hurricane Laura, which caused $13 billion in damage when it struck Southwestern Louisiana in late August.

The storms caused $43 billion in losses, almost half the total for all U.S. disasters last year.

In addition to the number of storms, the 2020 hurricane season was unusually devastating because climate change is making storms more likely to stall once they hit land

The next costliest category of natural disasters was convective storms, which includes thunderstorms, tornadoes, hailstorms and derechos, and caused $40 billion in losses last year.

Wildfires caused another $16 billion in losses. Last year’s wildfires stood out not just because of the numbers of acres burned or houses destroyed

Homeowners and governments around the United States need to do a better job of making buildings and communities more resilient to natural disasters

“We can’t, as an industry, continue to just collect more and more money, and rebuild and rebuild and rebuild in the same way,” Mr. Griffin said in an interview. “We’ve got to place an emphasis on preventing and reducing loss.”

The single costliest disaster of 2020 was a series of floods that hit China last summer, which according to Munich Re caused $17 billion worth of damage.

Of the $67 billion in losses from natural disasters across Asia last year, only $3 billion, or 4.5 percent, was covered by insurance.

Animal communication systems, in contrast, typically have at most a few dozen distinct calls, and they are used only to communicate immediate issues such as food, danger, threat, or reconciliation. Many of the sorts of meanings conveyed by chimpanzee communication have counterparts in human 'body language'.

The basic difficulty with studying the evolution of language is that the evidence is so sparse. Spoken languages don't leave fossils, and fossil skulls only tell us the overall shape and size of hominid brains, not what the brains could do

All present-day languages, including those of hunter-gatherer cultures, have lots of words, can be used to talk about anything under the sun, and can express negation. As far back as we have written records of human language - 5000 years or so - things look basically the same.

According to current thinking, the changes crucial for language were not just in the size of the brain, but in its character: the kinds of tasks it is suited to do - as it were, the 'software' it comes furnished with.

So the properties of human language are unique in the natural world.

About the only definitive evidence we have is the shape of the vocal tract (the mouth, tongue, and throat): Until anatomically modern humans, about 100,000 years ago, the shape of hominid vocal tracts didn't permit the modern range of speech sounds. But that doesn't mean that language necessarily began the

Some researchers even propose that language began as sign language, then (gradually or suddenly) switched to the vocal modality, leaving modern gesture as a residue.

. In an early stage, sounds would have been used to name a wide range of objects and actions in the environment, and individuals would be able to invent new vocabulary items to talk about new things

In order to achieve a large vocabulary, an important advance would have been the ability to 'digitize' signals into sequences of discrete speech sounds - consonants and vowels - rather than unstructured calls.

These two changes alone would yield a communication system of single signals - better than the chimpanzee system but far from modern language. A next plausible step would be the ability to string together several such 'words' to create a message built out of the meanings of its parts.

This has led some researchers to propose that the system of 'protolanguage' is still present in modern human brains, hidden under the modern system except when the latter is impaired or not yet developed.

Again, it's very hard to tell. We do know that something important happened in the human line between 100,000 and 50,000 years ago: This is when we start to find cultural artifacts such as art and ritual objects, evidence of what we would call civilization.

One tantalizing source of evidence has emerged recently. A mutation in a gene called FOXP2 has been shown to lead to deficits in language as well as in control of the face and mouth. This gene is a slightly altered version of a gene found in apes, and it seems to have achieved its present form between 200,000 and 100,000 years ago.

Nevertheless, if we are ever going to learn more about how the human language ability evolved, the most promising evidence will probably come from the human genome, which preserves so much of our species' history. The challenge for the future will be to decode it.

upervised learning depends on annotated data: images, audio or text that is painstakingly labeled by hordes of workers. They circle people or outline bicycles on pictures of street traffic. The labeled data is fed to computer algorithms, teaching the algorithms what to look for. After ingesting millions of labeled images, the algorithms become expert at recognizing what they have been taught to see.

There is also reinforcement learning, with very limited supervision that does not rely on training data. Reinforcement learning in computer science,

is modeled after reward-driven learning in the brain: Think of a rat learning to push a lever to receive a pellet of food. The strategy has been developed to teach computer systems to take actions.

A more inclusive term for the future of A.I., he said, is “predictive learning,” meaning systems that not only recognize patterns but also p

redict outcomes and choose a course of action. “Everybody agrees we need predictive learning, but we disagree about how to get there,”

My money is on self-supervised learning,” he said, referring to computer systems that ingest huge amounts of unlabeled data and make sense of it all without supervision or reward. He is working on models that learn by observation, accumulating enough background knowledge that some sort of common sense can emerge.

A huge fraction of what we do in our day-to-day jobs is constantly refining our mental models of the world and then using those mental models to solve problems,” he said. “That encapsulates an awful lot of what we’d like A.I. to do.”Image

Currently, robots can operate only in well-defined environments with little variation.

“Our working assumption is that if we build sufficiently general algorithms, then all we really have to do, once that’s done, is to put them in robots that are out there in the real world doing real things,”
