    The kids who used AI and studied for a similar amount of time as the non-AI high performers apparently had similar (slightly higher) performance. The kids who used AI and did poorly used the AI to do the homework for them (this is what the article says).

    I believe AI is basically an amplifier of bad and good. I’m cynical about the world and assume it will be used more for bad than good, but I don’t doubt some of the best people in every field will be using AI to amplify their work in good ways.

      This is kind of damning, isn't it? "Similar or slightly higher" for spending the _same time_ means it's not, in fact, helping. At the same time as being extremely damaging to a significant number of students who, of course, use the AI to cheat. Because everything about it makes cheating easy.

      It's not so clear that AI is an amplifier.. The paper has some fascinating analysis on this topic:

      "At the other end of the distribution, AI students who spend more than 65 minutes on their homework receive homework and exam scores similar to those of non-AI students, suggesting that these students do not use generative AI for homework assignments. However, this group consists entirely of students who adopted generative AI no more than Öve months. Six months after adoption, no AI student spends more than 65 minutes completing their homework (see Figure A5). This is consistent with the gradual process of learning how to use AI tools. It also suggests that AI crowds out the highest level of e§ort."

      "Interestingly, in the range of 50-65 minutes, the median and the interquartile range of exam scores of AI and non-AI students are similar. This implies that, in the range where AI students and non-AI students have overlapping homework times, students who spend the same amount of time completing homework on average receive similar exam scores."

      "This pattern shows that students who spend the same amount of time on homework learn similarly, with or without generative AI. In other words, generative AI reduces time spent learning for the majority of AI students but not learning efficiency for those who spend the same time studying as the non-AI students."

        Depends who's using it. Like many tools the force multiplier depends on the operator.

        I'm confident it's an amplifier for people who know how learning works and already do a lot of it, successfully. However the level of "learning fluency" I'm talking about isn't reached for many until late college or grad school, and sometimes not at all. So I'm not surprised by the quoted results for 12-18 year olds.

          And people who want to learn. Most teenagers lack agency in their studies. They aren't in high school because they love it but because they have no choice.

        It would be good to see the effect of access to AI during preparation on those who previously achieved top 10% points in exams of similar topics before. I suspect they would benefit further.
        • kzz102 34 minutes ago
          My apologies for coming off as over-enthusiastic, I am currently obsessed with this study. Here is another quote:

          "The negative learning effects are larger for students with higher initial achievement. The differences in the estimated full (6-10 month average) effects are substantial, with a 50% gap between the most negative effect (-24 percent) for the highest tercile and the least negative (-16 percent) for the lowest tercile. "

          Not top 10% as you asked, but the closest to what you asked. My working hypothesis is that top performance is highly correlated with willingness to work hard, and AI decreases the motivation to work hard.

          • bonoboTP 20 minutes ago
            Interesting. Top academic performance is mostly correlated with conscientiousness (willingness to work hard and keeping track of things) and intelligence. And I'd add motivation and interest to that too.

            I think if you take a physics class where the student is intelligent and intrinsically motivated through their own interest (I admit this is rare) then AI probably helps.

        well most university exams are designed to measure how much you study. so we didn't really need a study to tell us, "Exams continue to measure what they are designed to measure."

        they're not designed to measure general aptitude, or function as admissions criteria, or screen for job applications, or any other numerous things they are used for.

        there can be many questions of pedagogy. one of them is, what do our exams measure and how do we use them? professors who say, "My exam is designed to measure who studies, not be used for all these other purposes that they are actually used for" - I don't buy it. It's the same as late night comedians saying they are not responsible for solutions, even when spending 90% of their air time making political jokes.

        THIS is the pedagogical issue, that pedagogy has NEVER caught up with the scope of responsibilities. This is acute in STEM - I mean, the humanities departments are generally pretty well run, all things considered, in this regard. Generative AI is accelerating that pre-existing crisis.

        • kzz102 44 minutes ago
          The fact that exam scores are correlated with how much you study is not the same as exams only reflect how much you study. Two students who study the same amount could have very different exam scores. The reason that there still is a strong correlation between exam score and time of study is because if all other things being equal, students who studies more have higher exam scores.

          > well most university exams are designed to measure how much you study.

          Huh? They're designed to measure how much you know. They can't see how much you study, nor would they have reason to be interested.

          • doctorpangloss 49 minutes ago
            at least in my experience in university - i didn't really ask this question, since it is obvious to me, but some students have asked it during lecture, or some instructors have volunteered the answer ahead of time - if you ask how to perform better on the exam, usually the instructors say, "here's what you should study." they never say, "know more." the thing i am talking about is consistent with the paper. really, your takeaway should be, exams can't see how much you know!
            • bonoboTP 38 minutes ago
              Because "know more" isn't actionable. Knowing more is achieved by studying but not necessarily more time spent studying, but well spent effort. Staring at the page for hours and saying "I don't understand" doesn't help. Solve exercise problems, explain the material to fellow students, discuss it with them, make mind maps, bullet point summaries, work through derivations step by step, etc. There are many techniques.

              At the end of the day though what matters is what you know. Furthermore, if it's a serious subject, it shouldn't matter whether you learned it from this teacher or from another school and teacher, as long as your knowledge is correct. Knowing the idiosyncracies of this particular teacher should not factor into the grade. A serious subject can be learned on one continent and examined on another. Bullshit courses are all about learning pet peeves and hobby horses of a particular teacher.

              I would usually say something along the lines of “everything we covered is on the table” or “everything we covered since the last exam is on the table” depending on the nature of the test. That’s the same message as “know more” but I think it sounds politer.

      The scary thing is that 81% of AI users in this study were determined to be "outsourcing" their homework to the LLMs - and the rate increases the more exposure they had to LLMs.

      The "slightly higher" performance is based on statistically insignificant samples (between 4 and 20 students, depending on the context, out of the total population of 26,000): https://bsky.app/profile/benjaminjriley.bsky.social/post/3mt...

        I thought that it was generally accepted by now that homework in the volumes that it is being assigned in the modern day was not found to be beneficial in any significant way in the first place? Maybe once all students start outsourcing it to AI it might finally die like it deserves to. People these days grow up with almost no free time for themselves, it's all school, sports/extracurriculars or homework nonstop. All worker drone and no play makes for an increasingly dysfunctional society.

          How do you expect students to learn anything when:

          1. They don't do any homework.

          2. All the in-class time is split between the teacher babysitting and playing social worker to problem students, and lecturing, with little to no opportunity to actually practice what they've learned?

          I understand that some students don't have home environments that are conductive to doing homework well. I understand that some students are enrolled in five hours a day of extracurricular university-application-padding activities. I understand that some students have incredibly poor screen discipline and impulse control.

          But I don't understand that anyone has magically figured out how to teach complicated things to students, and have it stick without them spending a lot of time practicing what they are learning.

          As anyone who has tried to do something hard knows, the first step to being good at something is to spend a lot of time being pretty shit at it.

          A student who has written and received feedback on 500,000 written words is going to be way better at writing than that same student who wrote 50,000, just like someone who has put 5,000 hours of focused practice into playing the piano is going to be better than my dumb ass, who has only put 100 hours in.

          (If you found the solution to get good at stuff without practicing it, I'd love to get good at piano without putting any homework in on it.)

        • idiotsecant 52 minutes ago
          All play and no work makes for an even more dysfunctional society. Kids need to do their homework, both to train their minds but also to develop integrity and work ethic. Being able to diligently work toward a distant goal is not something you're born with.
    • jknoepfler 9 minutes ago
      It's a familiar story. If you copy/paste Wikipedia and turn it in, you learn nothing. If you skim Wikipedia, hit up the references, the consult other sources, then synthesize your own thought, you probably get farther faster than you would without it.

      We could probably cook up thousands of examples of the same problem (YouTube DIY tutorials, GPS navigation, etc.)

        Definitely had a sheltered public school experience, took AP stats my senior year and realized all the top students were sharing answers from an earlier period through text messages. After figuring this out I too joined in on the action, then shortly after I quickly deskilled.

        Suppose it's good to learn how elastic the brain is, in both directions, at a young age where it doesn't matter.

    • BrenBarn 2 hours ago
      The dangerous thing about amplifying is that bad people are often more willing to amplify their activities, because they don't care about the negative effects. We are seeing this now as AI companies (and large companies of all kinds) rush to secure whatever advantages they can, regardless of the negative externalities. Meanwhile people who actually care about doing the right thing get trampled.

      We need to shift the incentives by adding ruinous penalties for things that are currently quite commonplace if they are done by large players. Some dude training his own AI on his own computer can scrape and train. The fine for OpenAI or Meta using a single copyrighted book without permission should be in the tens or hundreds of millions.

      What we're seeing currently in our society is a "loophole inversion" where the rules have an effect mainly via their loopholes. The most profitable activity is to find loopholes and exploit them as frenetically as possible to gain as much advantage as you can before the loophole is closed, or get people hooked on the loophole so it's retroactively legalized. Entities that are big enough to do this are big enough because they have lots of money behind them. Entities doing the same kinds of things without lots of money are not really doing much harm. So the best approach is to adopt a "sliding scale" in which even tiny violations by wealthy actors result in penalties enormously greater than fairly large violations by small players.

      • grey-area 2 hours ago
        There is zero evidence for this.

        LLMs make significant mistakes frequently and smart people have no way of judging those mistakes outside their domain expertise. They are also sycophantic and great at being an echo chamber which makes people feel smart even if they are not.

        So I think the burden of proof is on you to prove that they somehow amplify intelligence, it seems highly unlikely.

        • ndriscoll 2 hours ago
          Most domains have some kind of internal consistency/theory building you can do. A smart person can certainly notice inconsistencies when trying to learn something. In fact they're likely to be points of confusion that the smart person will dive into just to try to make sense of things, even if they don't suspect the LLM is at fault.
        • Barbing 1 hour ago
          No evidence but somewhat of a counterpoints:

          Smart people know LLMs confabulate and tell them they’re Absolutely Right! Smart people don’t want to be embarrassed by trusting the hallucination machine and revealing their gullibility to others.

        • ACow_Adonis 21 minutes ago
          Why would a smart person go to an LLM for an answer they cannot judge or test, be succeptible to flattery and sycophancy rather than picking up on the emotional manipulation and being suspicious/sceptical of the interaction, or looking for support from an echo chamber rather than a Socratic opponent?

          All of those sound like flaws and defects of dumb people?

        Raising the noise floor like this only makes it that much harder to find "Smart" people, which we were already doing terrible at.

        I use Claude every single day, but this is such a bad tradeoff. Maybe it will help me standup a quick fix when that is needed. Maybe it can help me dig through documentation to find relevant bits and figure out the unstated assumptions underlying it. Maybe it helps me generate test cases.

        Meanwhile, my day to day life is now noise. All social media is noise. All content is noise. Slop pours onto me from all directions. Writing more test cases isn't helping me.

        • suburban_strike 2 hours ago
          All I've noticed is AI creating a perverse incentive to make everything as complicated and bureaucratic as possible, so only the people that know how to leverage AI to cut through it ever succeed.

          I'm using Claude at work myself and am impressed with the product, but notice that this is the only reason I need to use it at all. Our product pages were shit to begin with, now they're AI-generated and somehow even worse. Our procedures are incomprehensible spaghetti with enough arbitrary context switching to give a sadistic Soviet municipal administrator an erection at the thought of watching anyone try to actually follow them.

          Use AI to create inefficiencies, then use AI to bypass them. Those who can't do the latter will struggle to survive.

          > Raising the noise floor like this only makes it that much harder to find "Smart" people,

          It does give us a new heuristic, though: people who are willing to completely cut generative AI out of their lives (cold-turkey, if you ever started using it) are a much smaller group of, predominantly thoughtful, people. You do have to give up Claude to be part of this group, but from what you say, that's no great loss, and no longer being deafened is worth it.

          This has considerable advantages over conventional elitism, because the barrier-to-entry is negative in almost all cases.

          The one exception I've found is assistive tech, where the state-of-the-art is so poor that vibecoded slop is genuinely an improvement over the state-of-the-art, and in many cases the tooling simply isn't available to make your own assistive tech (unless you want to bootstrap an entire networked computing environment, which isn't very helpful when you want to do your online banking and do not, in fact, work at your bank).

          But there are not many principled exceptions where you could seriously argue that the trade-off is worth it. Take mathematics, for example, which we often see touted as a "good use-case" of generative AI. The primary advantage of generative AI in mathematics is being able to search though a vast corpus of ivory towers and inconsistent terminology (without proper attribution) to locate and connect ideas that can help solve problems. The deficiency this is addressing is elitism, inadequate communication, and inadequate indexing within academic mathematics. This problem is entirely created by the academic mathematicians, and has been known for nearly a century (per https://en.wikipedia.org/w/index.php?title=Nicolas_Bourbaki&...):

          > Bourbaki was founded in response to the effects of the First World War which caused the death of a generation of French mathematicians; as a result, young university instructors were forced to use dated texts. While teaching at the University of Strasbourg, Henri Cartan complained to his colleague André Weil of the inadequacy of available course material, which prompted Weil to propose a meeting with others in Paris to collectively write a modern analysis textbook.

          To my knowledge, this is the only organised project to clean up and improve mathematical communication. Everything else (Metamath, Mizar, AFP, Lean) is yet another ivory tower. The Wikipedia article on this topic (https://en.wikipedia.org/wiki/Mathematical_knowledge_managem...) risks deletion as non-notable, that's how little anyone's actually trying. They made their own bed, and generative AI will only provide a brief respite from having to lie in it. (I was surprised how many other "compelling" use-cases evaporated when I applied this razor to them: the sibling comment https://news.ycombinator.com/item?id=49392265 points out one such.)

          Vibe-coding assistive tech which doesn't yet exist, as a temporary scaffold to improve the quality-of-life of yourself and others in a social world dominated by non-essential access barriers is, to my knowledge, the only exception to this principle that can be justified. If you treat people who make other excuses, or who don't even bother with excuses, as not worth listening to, you lose little – and doubly-so, if you make your stance clear, so that others know the "cost" of gaining your attention.

    All AI did here is exposed an old problem in education. Kids are expected to get everything perfectly for the first time but a lot of them don't so the class gets easier next year to keep up pass rates.

    We need to restructure the system to treat failure as a signal instead of a disaster. Grades should come from hard randomized exams with unlimited retakes so one bad day won't hurt you. Homework should be optional material for self study, evaluated by teachers if you choose to do it but never forced.

    Hold back students for individual classes instead of a whole grade so failing one can't ruin your social life and teachers are more willing to do it. F students will realize they have to study, start actually learning and then pass on the second time. No big deal. It happened to my friends in college, no reason they can't do it in high schools.

    Discipline is a skill and it's one you have to get from experience. If you try and force kids to study when they don't want to "for their own good" you're not actually helping them. Everyone needs to find their own path. Let people fail.

      > Homework should be optional material for self study

      At Caltech, homework was assigned but had no bearing on your grade. The grades were based on the midterm and final exams.

      But not mastering the homework usually resulted in flunking the exams. There were "retch" sessions after each homework assignment that was staffed by a grad student, and the purpose was to help the students understand the homework problems. I knew only one person (Hal Finney) who was so smart he didn't need to do the homework.

      I learned the hard way that the path to success was:

      1. never miss a lecture, no matter what

      2. take notes by hand during lecture

      3. do the homework on time, and make sure you understand every problem. Take advantage of the retch sessions.

      And that worked for me.

      • CobaltFire 43 minutes ago
        Naval Nuclear Power School had (maybe still does) this model 20 years ago as well. Pass rate for my class cohort was 28% over the entire 2 year pipeline.

        We didn't call them retch sessions, and they were taught by the instructors though. We also were encouraged to peer tutor and since we were all restricted to one building the homework was always group work allowed.

        Also had badges to track time spent in the building for required study hours, though some people gave up and just slept at their desks when they started sliding down the grade scale and the hours racked up.

        Generally I think I did 30 hours of studying/homework (went up and down depending on what was being taught, but was around that) a week (for 12-15 hours of actual lecturing), with some of my friends putting in 50% more. Generally the only day we weren't there was Saturdays. Most of the day Sunday was usually spent in class preparing for the next week.

      • WalterBright 1 hour ago
        I've given this advice many times, and the ones who followed it did well. I only added "leave your laptop in your dorm room" for modern times.

        The general pattern at Caltech was 2 hours of study for every hour of lecture. Which was quite a shock to me.

        • nrr 47 minutes ago
          I'll add one more thing to this, given that my experience as a math major at SIU was that each hour of lecture was expected to carry four hours of studying: read and summarize the course's texts (additionally, for math courses, attempt the problems) before lecture.

          I found that (1) I didn't need to take anywhere near as many notes during lecture and (2) I could ask way, way, way more relevant questions.

          This also helped tremendously when it came to studying for the actuarial exams.

      • moffkalast 58 minutes ago
        That only works with competent lecturers. I can speak for my experience at a more mid university, where that would apply to about two thirds of the classes. For the remaining third, going to the lectures felt genuinely counterproductive and you could actually feel yourself losing braincells listening to the confused nonsense or classes held in English for Erasmus students by someone who could barely speak it coherently. It was just a complete waste of already little available time.

        So the endgame was figuring out what the tests in previous years looked like (cause it was likely gonna be a copy paste affair), do a targeted study run for those exercises and 9/10 you would pass.

        > 1. never miss a lecture, no matter what

        As a student of a top-tier French Master's degree, I consulted with a teacher to deal with exhaustion and to ask for a class rescheduling for my case. Explaining my situation, the teacher looks at me and interjected:

        —Waitwaitwait. You... you went to all lectures!?

        And he was right. Rather than following the curriculum, I should have developed my taste for various engineering topics and only used the classes as entertainment.

        • bonoboTP 28 minutes ago
          I think the first semester, or at least half of that, you should go to every lecture until you develop taste for what's useful. By the time you do your master's you should have a good sense for what classes are serious and have useful lectures and where you can just cram last minute because it's a bullshit class and where you're better off studying from a textbook.

        do you have any evidence that CalTech's pedagogy is immune to today's threats and trends in education everywhere else? (no)
        • WalterBright 1 hour ago
          Nope.

          When I was there, a long time ago, exams were timed and were usually open book open note. Blue books were filled in. You were trusted to adhere by those rules, and most students did their exams in their dorm rooms.

          The evidence that the students honored the rules was some exams resulted in a 50% failure rate.

          As for me, I went there because I wanted to learn the material. I did not care about getting a diploma. (Mine is in the basement somewhere.) I did not take any "easy A" classes, because I wanted a return on my time and tuition investment. (Though, easy A classes were hard to find at Caltech.) I wasn't even going to attend graduation, but my parents showed up and I attended to please them.

          The classes, year by year, were dependent on mastering the previous year's classes. So if you cheat with AI, you're digging yourself into a bigger and bigger hole. Caltech rewires your brain. If you don't learn the stuff, you're going to be one of those EEs who carries around a card with V=A*R, V/A=R, V/R=A printed on it.

      Unlimited retakes would be an enormous amount of work for professors/TAs/teachers.

      Optional homework is often a disaster. At best, students would do it right before an exam and the goal of education is not to just pass exams. They’d probably still get a lower score than if they did the homework when they were supposed to.

      What I think is better is to have a due date, but just make the maximum 10% each day it is late. So after 2 days, the highest score you could receive would be 80%.

      I liked that system because it gave some flexibility with deadlines while still encouraging you to turn things in on time.

    • Yhippa 47 minutes ago
      What you described about exams is like how I approach most certification exams: go through a test bank of questions until I get 80% then take the real test.
    • yorwba 1 hour ago
      The study was done in China, where making the class easier to improve pass rates isn't really a thing, as the Gaokao operates more like a stack ranking where it doesn't matter much how well you did in an absolute sense, only that not too many others who did better than you are competing for the same spot. Unlimited retakes are possible in theory, except each costs you a year of your life and except for some extreme cases of repeat test-takers, most people are going to give up after just one or two bad results. Homework is definitely not optional, but going home from school is. (Due to the hukou system, children often have to go to school far from where their parents work, so boarding schools with teacher-supervised self-study are common.) I don't see how holding back for individual classes is supposed to work considering scheduling conflicts.

      Do you have evidence for this beyond your friends (who were accepted into college)?

      It's all cute but naively glances over what this all boils to - competition.

      Education system, contrary to popular belief/name, isn't tailored to educate but to select winners and losers which then will be picked on the job market.

      That's why it seems absurd when you think about it as an institution that aims to educate. That's because that isn't the real purpose of it. The purpose is to stratify and classify early.

      Schools do not operate in a vacuum; they serve as credentialing gatekeepers for a hyper-competitive capitalist job market. If everyone could easily retake exams until they got an A, grades would lose their primary utility for employers and universities: differentiation. Society relies on schools to provide a neat hierarchy of candidates that for one reason or another thrived in difficult environment of adolescent schooling.

      The system often prioritizes compliance, endurance of boredom, and social maneuvering over actual critical thinking precisely because those traits align with corporate hierarchies.

        I could be mistaken but my interpretation is that "studying for your own good" is being contrasted with "studying so you don't fail". If you actually fail students, they'll have a second motivation beyond trusting some authority figure's advice. Namely consequences.

    Moneyshot: "The results are eye-opening. After six months, pupils using ai saw their average homework score rise by 18% across all subjects. The time they took to complete each assignment fell from an average of 64 minutes to 45. But come exam time, the same students scored 20% below their classmates who had not called on ai’s help. Homework scores once predicted exam performance; now those who score highest are, perversely, more likely to do worse in exams."

    Study design: "David Stromberg of Stockholm University and Victor Lei and Wu Yanhui of the University of Hong Kong set out to fill the gap. They tracked 27,000 pupils aged 12-18 in China, where ai adoption has been fast. Around 80% reported using models such as Doubao and DeepSeek; the other 20% formed the control group."

      As with most training the journey is the point, not the destination.

      That said, I think smart use of AI could help. It could explain concepts in a way that might help you understand better, it could probe your knowledge in a more dynamic way by tailoring questions, and so on. This requires the AI be restrained by some harness, not free to write down the answers for you.

          When I was in college, we had office hours with the prof and the TAs, we had group study sessions, and private tutors. Or you could ask your friends. All of those required going somewhere at a specific place and time and asking someone else to give up their time for you.

          AI gives you a way to get the same help without asking another human. Say of that what you will, but not everyone was comfortable asking other humans for help even back then.

            Kids are, by and large, lazy however. Hell, adults are lazy, this isn't even an indictment on kids or even people in general, I think our bodies & brains are simply wired to seek the path of least resistance from an evolutionary POV.

            Kids won't be using LLM tooling as a personal tutor following some sort of Socratic method, they'll ask it to solve their home/coursework for them and blindly copy/paste the answer. Hell, they'll just manually copy down what's on their screen if copy/pasting isn't possible for whatever reason.

            Obviously exceptions exist, but I'd wager from being an ex-kid myself the type of kid who would genuinely use these tools for actual proper self-tutoring would be an extreme rarity.

        I did this for the last college programming course I taught (2025) as an anti-LLM measure. Every class started with a very short closed-book auto-graded multiple-choice test on the reading. I was careful to specify which was the core reading needed to learn the material (on the quiz) and which was extra (not on the quiz - I think many professors assign this extra reading to everyone, thinking of their strongest students). I think this developed an expectation in the students that doing the reading was easier than finding a way not to.

      This is typical at the college/university level - when I attended 20-25 years ago, we were expected to learn the material through readings outside of class, and then class time was spent on discussion, application, questions, and working through problems.

      IMHO there's a lot to recommend this style. A lot of students learn better when they can wrestle with the material at their own pace, on their own time, in their own setting. It quells a lot of anxiety about "I'm not following what the teacher is saying, am I stuped, will I look bad in front of all my peers?" And then class time can be spent identifying holes in your knowledge and getting instant feedback from an expert, which is where they are most useful.

        • nostrademons 17 minutes ago
          I think it makes sense as soon as students have the fundamentals down. You have to be able to read, listen, make connections, think critically, devote sustained attention to a task, and manage your time effectively. Some students develop these skills in elementary school, and then starting in middle school, the flipped classroom approach can work. Some adults never develop these skills. Although arguably, people that never develop these skills will likely be sitting there zoning out in a traditional classroom lecture and not actually learn anything.

            IMHO, my kid was assigned way too much homework. One year I eventually told her to do some amount per class (I think it was 45 minutes) and then be done with it so that she would have time for sports and family stuff. She was spending 4 or 5 hours every night on homework and this was in 4th grade.

            That year I sent an email to her teacher to let them know that I'm the one responsible for her not doing all the work and if that's a problem, we need to talk. It wasn't a problem.

            The one class that was flipped was a relief because she could breeze through the lesson much faster than would normally be spent on it in class and the amount of time on exercises was limited to the class time slot.

      I see this as a memorize-vs-understand fallacy many repeat.

      It is really a combination: you need to memorize a large corpus of information to operationalize knowledge — understanding a bunch of theorems in mathematics does not help much (even if you are able to prove them when you see them) if you can't remember the boundary conditions they hold under.

      Or having good understanding of foreign language grammar won't help you if you do not memorize words that you need to express your thoughts.

      Good literature will show you some of life's challenges and potentially let you think through them in a non-stressful situation (other than "I've got to finish the last 200 pages by Monday" ;)).

      Maybe. As the nature of assistive tools changes, so does pedagogy. Calculators are the easy example since most of us are (still) familiar. But there are others that were just as pronounced -- e.g. log tables and slide rules were transformational and instrumental at one time, and you've (probably) never used them. If you had used slide rules to solve your homework problems then were excluded from using them on exams, you'd see a similar effect.

      AI is a big change; pedagogy is going to change too.

We know pretty well from centuries of empirical experimentation how children's brains develop under different stimuli. It's not exactly something the software industry needed to "hack".

      Stand-alone bottom-up observations (even if valid) obscure the fundamental problem that AI (or "AI" if you like) is inducing systemic change across human civilization.

      If cohorts are graduating into the workforce with decreasing stand-alone skills, that implies the economic value-add of labour is shifting to AI, which implies broadly falling standards of living, falling political power, and an ongoing transfer of power and wealth to capital.

      If students are taking shortcuts with AI when their brains have the highest capacity for learning they may be permanently weakening their prospects. It doesn't seem likely that whatever "AI management skills" they incidentally learn will make up for, over their lifetime, the economic value loss they suffer due to reduced cognitive skills.

      Way before AI, the problem was very similar - universities do not teach practically useful stuff. Its been a permanent complaint about the education system, really, at least for the last 50 years.

      AI just gave the students a way to dodge the slog.

      But university was never intended to teach the bleeding edge. That would really be impossible in practice. Pre-phd, it is supposed to teach ways to efficiently attack a problem. you can take a bunch of "play courses", and succeeding at any of those requires pretty much only that one skill.

      Nowadays, the challenge they face, is to keep teaching "problem attack methods" in a way that can't be trivialized by AI.

      Though fundamentally, if you go to university, and evade learning the one thing you can learn there - thats your loss.

      The often underworked (most are autograding these days and reading old powerpoints rather than do real curriculum development) and (for the quality) overpaid teachers/professors will mass riot against this because it means they might have to actually teach. We might even get yet more anti-boy treatment than already exists among them as a social class in retaliation.

      Please also abolish PowerPoint and force oral exams while you are at it.

      Teachers are also luddites as a social class. Math teachers cried about calculators yet everyone of them who refused to adapt did disservice to their students (especially anyone doing statistics). My state's education system is utter trash despite being well off economically because of strong teachers unions keeping them from undergoing even a tiny bit of scrutiny.

      They do not deserve the social credit/grace that they get. They are ultimately gatekeepers, whose extremely biased decisions in grading/treatment of their flocks decide which kid grows up on the streets and which kid grows up to eat lobster thermador every day.

      Teachers also should not be disciplinarians. Children with discipline problems bad enough to disrupt a whole class should be thrown out of the class room as basically the only thing a teacher does for "discipline". The "right to education for the shit kids means we can't do that" framing is such trash for those who want an education and will inevitably be disrupted by a small minority of terrible students.

      Also it's interesting that one of the only other things Max Stirner wrote about besides philosophy was education and his myriad problems with it (given his history as a school teacher).

      Everytime a student says this—it's because they're procrastinating on their work. The hardest part about anything new is starting it. Once you build some momentum, interest and focus tends to build as well.There certainly are some homework assignments that are boring.

      A child today can absolutely be successful at doing their homework if they have time to... sit down and write, or draw, or do crafts or things that require them to focus. It's not like Screens exist, therefore no attention span.

      What's happening is people are only fixating on screens, and foregoing these slower forms of media. That's akin to saying all children will be obese now that fast food is around. Of course, obesity rates will sky rocket if all you eat is fast food. But if a kid grows up to have homecooked meals, and eat with their parent(s) then they won't. It's as simple as that.

    Yes, using a calculator leads to worse outcomes in your learning. But also, yes, everyone always carries a calculator on their person 24/7 these days and you'll never be as fast and as accurate as a calculator.

    I think it would have been kinda cool if you could have unlocked the privilege of using a calculator in school through good grades in math class. Prove you can do what the tool can, then you get to use it. Would have also provided at least one incentive for students to get good grades in at least one class.

      The important thing is that I could learn to use a flint and steel pretty easily if I wanted to. I don't need to carry out that particular task, but my ability to adapt to new problems means I can carry out more relevant tasks when needed. The most useful part of school and university for me wasn't that I learned the difference between a cirrocumulus and a cirrostratus cloud in geography class. It's that I learned how to learn.

      If we let children cheat their way through school and justify it by saying they don't really need to think for themselves anymore, then we're going to end up with a generation of adults who struggle to take on any difficult tasks at all. I suppose your counter-argument to that will be "but we can just hand over everything to the AI" but that's an essentially an argument that humans should be considered obsolete altogether. I sincerely hope that that's not a path we end up going down (although I'm genuinely scared that it is).

      These are students aged 12-18. Even if we ignore all the other negative externalities of AI and assume it will be ubiquitous and cheap, kids need repetition and exercises to make inferences and develop intuition.

      Sure - you can ask AI to, for instance, calculate how much money you'll have given a fixed principal and a compounding interest rate. But we need to get a kid to the point where they even understand what the question to be answered is. If they're using AI all along the way, they are developing less understanding of what fractions and exponential growth are.

      Will it stop the really smart and motivated kids? Of course not. But at population scale there will be big consequences.

        I believe 4 things:

        1) We're building a tool that can make toil of every kind obsolete. We're not there yet, but I'm watching it happen in real time.

        2) The fact that it works so well economically means that it's inevitably going to take over. Humans simply won't be profitably employable, and this will happen sooner than you think.

        3) The takeover could lead to a utopia, where nothing is needed of anyone, and you could do what you want when you want it.

        4) Humans are likely fuck that up, and it's worth doing what you can to end up in the group that benefits. Sipping wine on the beach isn't mutually exclusive with a great deal going to the winners.

        I do not believe that human brains are magical, and I think that they can be surpassed with manufactured brains.

        Concerns over equitable the distribution is doesn't affect the value of skills.

        I get it, there's a strong anti-AI vibe here because of point 4. I'm somewhat worried, but I'm also really excited about the possiblilities, and I don't think we can avoid going to a fully AI future no matter how anti-AI you are; we can only figure out where to set the dial on how the rewards get shared.

      What is a doctor? The person recommending next course of action based on best practices. What is the best practice? Is it a globally decided on thing, a locally tested thing that has proven to be better? Is the global thing just the most popular because someone wrote it on reddit and it got millions of views (but isn't actually good).

      If our society is organized on just delegating all authority to "the best answer" we can drop all jobs - and only the surgeon has some authority over the machine. When we have a surgery robot, then they can go to. And at some point we'll be recommending and forcing surgery for athletes foot because some kind of best practice or viral post going out of control and a bunch of openclaw bots randomly decide to make tons of recommendations online for amputation for athletes foot and GPT 8.6 agrees this is the way to go.

        I actually think having a single source of truth would not be terrible. Let me explain.

        All podiatrists are not the same. All physicians in their specialties are often specializing in their own niche and are up-to-date on that niche.

        I've had lisfranc ligament injury. My podiatrist wanted to perform a surgery quickly, which in 90% of cases is advised. I decided to seek a 2nd opinion because I realized she did the X-rays wrong, as she did them non-weight bearing, which is useless if there are no fractures.

        The specialist was excited to see me, and up to date on all the lisfranc research. I've had a really bad sprain and he said conservative treatment should be sufficient. It took months but I healed up.

        I've had quite a few injuries from playing sports and often found doctors to be "wrong" simply because their knowledge was out of date.

        • Calavar 4 hours ago
          I am confused as to how this is an argument for a single source of truth. It seems like you've presented an argument for the opposite. If there were a single source of truth, there would be no point in seeking a second opinion - it would be the same as the first. If the first opinion was correct, excellent. But if the first opinion was incorrect (and no AI model is correct 100% of the time), then you're straight out of luck.
          • avgDev 4 hours ago
            The problem is that the first source is incorrect because she doesn't deal with lisfranc injuries frequently enough and her knowledge is not good enough. I've had to go do my own research to find a guy who specializes in lisfranc. Most patients would not.

            However, if you went to an AI agent which has access to medical research, you would get the most up to date research.

            Why would I seek a 2nd opinion if the initial doctor knew what to do?

      This is too simplistic. There are disciplines, like Anatomy, where you're basically just memorizing bones, glands, and other parts of the human body. For organic chemistry, students need to memorize most of the krebs cycle diagram for their exams (because doing so and drawing it lets them reference it later).

      Thinking is infinitely more complex than "critical thinking" vs. rote functions. You want students to get to critical, eventually, but the lower orders on bloom's taxonomy serve important roles, too.

      Course design built around multiple choice questions, essays, and a lot of the historical assessments that we're used to are largely not great for learning in the first place—–they're used because they can be auto-graded or score assigned quickly. AI, conversely, is kind of revealing the limitations of these outmoded learning design practices.

      Think of the meme going around right now from Milennials to Gen Z: "I wrote a 5 page essay on a book I never read!" <- They're saying this to AI generated essays as if there's any difference in the critical thinking that comes out of an exercise like that (read: absolutely none).

      AI is a new tech—so of course people are still figuring out the limits of it. In 10 years a lot of the paradigm will be set. Until then, students are unfortunately kind of in the thick of it.

      Open book tests and allowed cheat sheets already solve the memorization-is-not-required gap. It seems like allowing use of AI pushes that closer to thinking-is-not-required. And if no thinking is required, then how can you prove personal mastery?

      Mastery is about demonstrating skills. Skills take practice, hands down.

      AI can help us build better tools, provide tutoring, answer broad ranging questions, help relate concepts, and do reasoning for us. All of those things can be good in that they can help us acquire skills faster, e.g. with better practices and exercises. But it cannot replace actual time spent doing a thing.

        Wrong. Memorizing without understanding is pointless. And I'd argue that rote memorization does nothing to guide ones understanding. Because if you actually understand a subject deeply enough you can literally derive almost anything that would need to be memorized on the fly, and if you can't (say constants, or spec information, or anything else) you can simply surgically look it up online (or via an LLM).

      This is something that AI cannot replace. Viewing things as memorizing is the wrong take.
