One of the most important (if least discussed) findings in educational research concerns calculators.
Several meta-analyses have found that students who learn mathematics using calculators perform better on exams…so long as they retain access to their calculators. Once the calculators are removed, this advantage largely disappears and performance on procedural skills typically reverses (1, 2, 3).
This evidence suggests that, rather than boosting learning, calculators boost calculator-assisted performance. Students can become highly proficient at manipulating a machine to produce the ‘correct answer’ without developing the underlying knowledge and skills required to self-generate or genuinely understand that answer.
PRODUCTIVITY IS NOT LEARNING
The majority of digital tools have been built for productivity: they make experts more efficient by reducing the time and effort to complete cognitive tasks they already understand.
Consider statistics.
After nearly two decades in academia, I have become quite skilled at performing the required tests, procedures, and corrections required to find meaningful patterns in data. Unfortunately, performing these tasks manually can take hours (sometimes days).
Luckily, statistical software can complete them in mere seconds.
But this software only works for me because I already possess the deep statistical knowledge required to drive it. I can identify faulty inputs, recognize implausible outputs, and detect when the software has substituted one procedure for another. Although the machine performs the calculations, I remain responsible for the thinking, vetting, and adaptation.
When experts use a tool to make performance easier, we call this cognitive offloading: and it works because established expertise allows the user to maintain control over the tool. Cory Doctorow describes this relationship as a centaur: part human, part machine, but with the human head firmly in charge.
Unfortunately, novices (by definition) do not yet possess the knowledge required to meaningfully drive cognitive productivity tools. They lack the deep understanding required to isolate aberrant inputs, vet erroneous outputs, or creatively devise alternate yet accurate approaches. Oftentimes, the best they can do is copy words, press the prescribed buttons, and paste the resulting output.
This is not cognitive offloading – it’s now called cognitive outsourcing: when a tool is used to perform the very process a person is meant to be learning.
Whereas offloading is a way to demonstrate expertise, outsourcing typically prevents expertise from developing. Instead of becoming centaurs, novices risk become reverse-centaurs: the machine supplies the direction while the human performs the minor tasks required to keep it moving.
AI IS THE ULTIMATE OUTSOURCING MACHINE
Generative AI can formulate arguments, summarize readings, solve problems, supply ideas, and generate explanations. In other words, it can perform many of the cognitive operations students attend school to develop.
An expert may use AI as an offloading tool because that expert can interrogate its claims, reject false reasoning, input missing context, and repeatedly re-direct the machine. But a student who has not yet developed this knowledge cannot do the same.
Crucially, the same person can be both an offloader and an outsourcer.
If I ask AI to ask summarize an argument about the brain (my area of expertise) I am offloading: I am a centaur driving and correcting the machine. But if I ask the same AI to summarize an argument about car repair (a topic I know nothing about), I am outsourcing: I am a reverse-centaur being driven by a machine whose output I cannot meaningfully evaluate.
The transition from outsourcing to offloading has little to do with training on the machine or developing some generic ‘AI literacy’. It depends upon deep knowledge of the field in which the tool is being used.
This means we do not need to learn more about calculators to transform outsourcing into offloading – we need to learn more about mathematics.
WHY NEW YORK CITY IS RIGHT
This is why the NYC policy is so intelligent.
First, the city has not permanently banned AI. It has established a moratorium while its effects are examined. That is basic prudence: if schools are going to place a powerful new technology in front of children, it should first demonstrate basic efficacy, safety, and legality.
Second, although critics argue that restricting AI usage will damage children’s employment prospects, does anyone seriously believe an eight-year-old will struggle to find work in two decades because they did not spend their primary school days using the AI systems of 2026?
If AI training were genuinely more important than a general education, we would remove students from schools and have them prompt chatbots all day. Of course, nobody proposes this because we intuitively understand that a tool is only as useful as the knowledge brought to it.
Carpenters aren’t better at construction than I am because they can swing a hammer any better than I can. They are better because they deeply understand carpentry – those material, structures, and principles that make swinging a hammer meaningful in the first place.
K-12 does not exist to ensure children know how to operate the tools of today: it exists to ensure that, when confronted with the unpredictable tools of tomorrow, they’ll have something meaningful to do with them.
Operating AI is easy (some might say trivial). Developing the knowledge, judgement, imagination, and expertise required to use it meaningfully is extraordinarily difficult.
That’s the work of education.
SO NOW THEN…
Too often, we mistake the tool for the skill. But outside of rare cases (such as the piano or archery), the tool is not the skill: it’s merely a means through which skill is expressed.
This is why the popular warning that “AI will take your job” has morphed into “Experts using AI will take your job.”
I predict that soon that will soon be simplified even further to “Experts will take your job”.
Tools work beneath expertise – they cannot meaningfully substitute for expertise we have yet to acquire. Students are not experts: they are developing the broad knowledge and specific skills from which expertise will eventually emerge.
This is why NYC’s AI moratorium is the first evidence-based response to classroom AI use I have seen.




Thank you for writing this! The Coalition for an AI Moratorium (AIM Coalition), a group of parents, teachers, and advocates representing thousands of NYC parents, fought for a year to win this policy. We spent the year updating the DOE on the scientific literature around AI and ed tech, and giving them reading lists every time we met with them (including your work!) And we’re not done yet - we have major concerns about the pilot projects for high school and the carve outs in younger grades, so we’ll keep fighting to keep the DOE accountable to all students.

Excellent piece, Jared. I've sent this to my middle school academic leadership team (of which I am a part as HoD of middle school Humanities).
It is ironic that for most of my 30 years as an educator (25+, in fact), I served as an educational technology evangelist (ed tech teacher/coordinator, IT Director) -- and up until a few of years ago (after a couple of recent professional experiences in both USA schools and international schools) -- I probably would have been leading the AI-in-education vanguard.
But, after reading The Digital Delusion and The Anxious Generation, I shifted professional focus to Humanities -- my undergrad area of study and passion for teaching. In my teaching of middle school students, I use physical resources for learning:
- notebooks for notet aking & journaling
- printed (A3 size) text pieces for students to mark-up and annotate (margin notes);
- printed (A3 size) maps and diagrams for mark-up and annotation
- hand-written exit tickets
- physical manipulatives in learning experiences
- small group discussions (table talks and elbow partners)
- role play and simulation activities, etc.
I've gone as non-digital as I can within the parameters/confines of the high quality American curriculum (and English language) international school in which I teach.
At any rate, my message to the middle school academic team is below -- let's hope it leads to high quality discussions about how we help students engage in deep learning...
=====================
As we move forward this year, I wanted to raise awareness (raise the red flag, really) about AI use in Middle School.
Sure, it’s there, it’s become part of contemporary life, but for our pre-teens and teens (and younger, of course), it presents some serious challenges for learning — rather than the promise of a boost/revolution in learning.
To wit, please have a look at the latest article by Dr. Jared Cooney Horvath, neuroscientist/educator and author of The Digital Delusion (2025), as well as the SubStack of the same name.
His latest article entitled “Why NYC’s AI Moratorium Is An Incredibly Smart Move” posits AI use as "Cognitive Offload” for experts (those with extensive prior knowledge and skill sets within the subject/topic for which they are using AI to automate tasks) vs. "Cognitive Outsourcing” which occurs when novice learners (i.e., our students) use AI to do the thinking for them.
-------
"When experts use a tool to make performance easier, we call this cognitive offloading: and it works because established expertise allows the user to maintain control over the tool.
Unfortunately, novices (by definition) do not yet possess the knowledge required to meaningfully drive cognitive productivity tools. They lack the deep understanding required to isolate aberrant inputs, vet erroneous outputs, or creatively devise alternate yet accurate approaches. Oftentimes, the best they can do is copy words, press the prescribed buttons, and paste the resulting output.
This is not cognitive offloading – it’s now called cognitive outsourcing: when a tool is used to perform the very process a person is meant to be learning.
Whereas offloading is a way to demonstrate expertise, outsourcing typically prevents expertise from developing."
This, then, is the risk we expose our middle school students to when we have them use AI as a central tool for their learning. To put it bluntly, they won’t develop Deep Learning through Cognitive Outsourcing.
-------
"An expert may use AI as an offloading tool because that expert can interrogate its claims, reject false reasoning, input missing context, and repeatedly re-direct the machine. But a student who has not yet developed this knowledge cannot do the same.
The transition from outsourcing to offloading has little to do with training on the machine or developing some generic ‘AI literacy’. It depends upon deep knowledge of the field in which the tool is being used.
Tools work beneath expertise – they cannot meaningfully substitute for expertise we have yet to acquire. Students are not experts: they are developing the broad knowledge and specific skills from which expertise will eventually emerge."
-------
I believe we should very strongly look at limiting (if not outright imposing a moratorium) on AI use by students in middle school. We need to ask what formal scientific evidence we actually have that AI enhances middle students’ Deep Learning, as well as more data-driven assurances that AI use by middle school students will not be an exercise in Cognitive Outsourcing.
Teacher AI use, absolutely — we have expert knowledge in our profession and the experiential judgement to use AI to enhance our professional practice.
Apologies for this treatise so early in the morn. If you’ve made it this far, my gratitude. My hope is that by raising awareness we make decisions to implement new and honestly untested technology as tools for middle school student learning.
If you would like to see more research on this topic I have compiled a trove of recent peer-reviewed journals with analysis in these two presentations I developed this past summer:
