A high school student in São Paulo is completing a history essay. The essay is about the causes of the First World War. She has been using an AI assistant to help with the research — asking it questions about the alliance systems, the assassination in Sarajevo, the mobilisation plans. The AI has provided detailed, accurate, well-organised information. The essay she will submit reflects this information.
A graduate student in Oxford is preparing for his comprehensive examination. He has used AI tools throughout his doctoral preparation — using them to survey the literature in his field, to identify the key debates, to understand the methodological traditions he needs to know. He has studied this material, not just accepted it; but the AI has shaped what he knows and how he knows it.
A lawyer in Lagos is preparing a contract. She is using an AI assistant to draft the standard clauses, to check the language against established precedents, to identify potential issues she should flag to her client. The work that would have taken a junior associate three hours takes her forty minutes.
Three people, three contexts, three relationships with knowledge that are different from what they would have been five years ago. The AI is not just giving them information — it is changing how they relate to information, how they acquire it, how they verify it, how they remember it, and what it means to know something.
Three people, three contexts, three relationships with knowledge that are different from what they would have been five years ago. The AI is not just giving them information — it is changing how they relate to information, how they acquire it, how they verify it, how they remember it, and what it means to know something.
This is the deepest and least discussed consequence of the AI revolution: what it does to human cognition itself.
The Historical Context: How Tools Change Minds
The idea that cognitive tools change how humans think is not new — it is one of the most well-established findings in cognitive science and science and technology studies. Writing changed memory. Mathematics changed reasoning. The printing press changed how knowledge was stored and transmitted. Calculators changed how arithmetic was done. Search engines changed how information was retrieved.
Cognitive tool transitions — The recurring historical pattern by which the introduction of a new cognitive technology (writing, mathematics, printing, calculators, search engines, AI assistants) changes not just what humans can do but how they do it: the cognitive strategies they employ, the skills they develop and lose, the relationship between individual minds and the broader knowledge infrastructure of their society. AI assistants are the next step in this sequence — and like each previous step, they will reshape cognition in ways that are partly gain and partly loss.
Each of these cognitive tool transitions produced changes not just in what humans could do but in how they did it — in the cognitive strategies they employed, the skills they developed and lost, the relationship between individual minds and the broader knowledge infrastructure of their society.
Writing enabled external memory — the storage of information outside the human mind in a form that could be retrieved and shared. This changed the relationship between individuals and knowledge: a person with access to a large library could know far more than a person relying on their own memory. But it also changed how knowledge was organised and what was valued as expertise.
The printing press enabled the mass distribution of text and the standardisation of knowledge. It contributed to the scientific revolution, to the Reformation, to the development of modern states and modern cultures. It also changed what being educated meant — the skills of reading and writing became essential in ways they had not been before.
Three prior cognitive-tool transitions are particularly instructive for thinking about AI’s impact:
Writing (4th millennium BCE onward) enabled external memory — the storage of information outside the human mind in a form that could be retrieved and shared. Socrates, in Plato’s Phaedrus, objected to writing on the grounds that it would erode the internal memory that the oral tradition developed. He was not entirely wrong — writing did change the relationship between individuals and knowledge.
The printing press (Johannes Gutenberg, ~1440) enabled the mass distribution of text and the standardisation of knowledge. It contributed to the scientific revolution, to the Reformation, to the development of modern states and modern cultures. It also changed what being educated meant — the skills of reading and writing became essential in ways they had not been before.
Search engines (1990s onward) enabled instant access to an enormous quantity of indexed information. The availability of search — the ability to look up any fact in seconds — changed the cognitive strategies that knowledge workers used. Research that previously required days in a library could be done in hours at a computer. The skills of library research became less essential; the skills of query formulation and source evaluation became more important.
AI assistants represent the next step in this sequence — the transition from tools that retrieve existing knowledge to tools that synthesise, explain, and generate knowledge on demand. The cognitive impact of this transition is still in early stages, but the direction is visible.
The Retrieval Revolution: Beyond Search
The most immediate cognitive change produced by AI assistants is in how people retrieve information. Search engines changed information retrieval by enabling keyword-based access to indexed web pages. AI assistants change it further — by enabling natural language queries, by synthesising information from multiple sources, and by generating explanations rather than just locating source documents.
Retrieval vs. synthesis — A search engine retrieves: it locates documents that match a query and presents them to the user, who must read, evaluate, extract, and synthesise the relevant information themselves. An AI assistant synthesises: it reads, evaluates, extracts, and synthesises on the user’s behalf, presenting a finished answer rather than a list of documents. The difference is one of where the cognitive work happens — and which cognitive skills the user exercises.
The difference is not just one of convenience. It is a difference in what cognitive work is required of the user.
A search engine query requires the user to formulate a keyword query, evaluate a list of results, navigate to relevant sources, read those sources, extract the relevant information, and synthesise that information to answer the original question. This is a multi-step cognitive process that requires significant skill: skill in formulating queries, in evaluating source quality, in reading critically, in synthesising across multiple sources.
An AI assistant query requires the user to formulate a natural language question and evaluate the response. The synthesis, the extraction, and much of the source evaluation has been done by the AI. The cognitive demand is lower — but the cognitive skills being exercised are different. Less skill in information navigation and synthesis; more skill in prompt formulation and critical evaluation of AI outputs.
Whether this change in cognitive demand is a net improvement or a net loss depends on what you value and what skills you believe are important. If the information navigation and synthesis skills that search required were intrinsically valuable — not just instrumentally valuable for getting the information — then offloading them to AI is a cognitive loss. If they were purely instrumental — the goal was always the information, and the navigation was just the means — then offloading them to AI is a cognitive gain.
The most nuanced position is that both are partly true: the information navigation skills have some intrinsic value in terms of the cognitive habits and critical faculties they develop, and AI offloading of those skills has some cost. But the skills are also partly instrumental, and the time and cognitive resources freed by AI assistance can be devoted to higher-level tasks. The net effect depends on what those higher-level tasks are and whether the cognitive habits developed through information navigation were actually being maintained by the navigation task.
The Memory Transformation: What Happens When We Don’t Need to Remember
One of the most discussed cognitive science findings of the digital era is the “Google effect” — documented by Betsy Sparrow and colleagues in research published in Science in 2011. The finding was that people who expected to have access to information later (through Google) were less likely to remember the information itself but better at remembering where to find it. The availability of external memory changed how people allocated their internal memory — storing access routes rather than content.

The Google effect (Sparrow, Liu, Wegner, 2011) — The finding that people who expect to have future access to information (through Google) are less likely to remember the information itself but better at remembering where to find it. The availability of external memory changes how people allocate their internal memory — storing access routes rather than content. The effect was the foundational documentation of how digital information access reshapes human memory strategies.
AI assistants extend this dynamic significantly. If a person can get a detailed, accurate, synthesised account of any topic on demand from an AI assistant, what is the value of storing that information in biological memory?
The question is not merely academic. Human memory is not just a storage system — it is an active cognitive substrate that shapes how we think, what connections we make, how we understand new information. The knowledge that is in a person’s head — that is part of their active cognitive repertoire — influences their thinking in ways that knowledge that is “out there and accessible” does not.

The knowledge that is in a person’s head — that is part of their active cognitive repertoire — influences their thinking in ways that knowledge that is “out there and accessible” does not.
A historian who has deeply memorised the sequence of events in a specific historical period thinks about new historical information differently from a historian who can look up those events but has not internalised them. The internalised knowledge structures new information — it provides a framework for understanding significance, for recognising patterns, for generating insights. The externalised knowledge provides a resource for verification and elaboration, but it does not provide the same cognitive scaffolding.
This distinction — between knowledge as part of active cognitive architecture and knowledge as external resource — becomes more important as AI assistants become more capable and more accessible. The information that people actively carry in their minds may gradually shift toward the kinds of information that cannot be effectively externalised: procedural skills, aesthetic sensibilities, ethical intuitions, relational knowledge.

The Learning Question: What AI Does to Education
The educational implications of AI assistants are among the most actively debated consequences of the AI revolution, and they connect directly to the deeper question of what learning is for.
The surface-level concern — that students will use AI to do their homework without learning — has been the focus of much of the public discourse about AI in education. This concern is real but limited. Beneath it is a more fundamental question: if AI can do much of what education has traditionally aimed to produce, what should education aim to produce instead?
The surface-level concern — that students will use AI to do their homework without learning — has been the focus of much of the public discourse about AI in education. This concern is real but limited. Beneath it is a more fundamental question: if AI can do much of what education has traditionally aimed to produce, what should education aim to produce instead?
Traditional education has aimed, in significant part, at producing people who can do things — write essays, solve mathematical problems, analyse texts, conduct scientific experiments. The specific skills required for these tasks have been the content of education. If AI can do these tasks, the justification for learning them changes.
The argument that the skills themselves are the point — that the process of learning to write essays, even if the essay could be AI-generated, develops cognitive capacities that matter independent of the specific essay — is important and partially right. Writing is not just producing text; it is clarifying thought, developing arguments, understanding evidence. The cognitive work of writing develops capacities that are valuable even if the specific written product could be AI-generated.
But the argument needs to be pressed more carefully than it often is. The claim that “the process is the point” can be a conservative rationalisation — a way of insisting on traditional educational practices without examining whether those practices actually produce the cognitive development they are supposed to produce. If students can learn to think clearly, to develop and defend arguments, to understand evidence, through processes that engage AI rather than processes that exclude it, the engagement of AI may not be cognitively harmful and might even be beneficial.

The most productive approach to AI in education may be to design educational experiences that explicitly use AI as a thinking partner — not to do students’ work for them but to scaffold their thinking, to provide feedback, to challenge their arguments, to help them identify the gaps in their understanding. A student who uses AI to improve their essay by engaging with the AI’s critique of their argument may be learning more than a student who writes the essay without AI assistance in a context where the essay is not engaging enough feedback to improve.

The Expertise Question: What AI Does to Professional Knowledge
The relationship between AI and expertise is one of the most consequential and most contested dimensions of the cognitive impact of AI.
Expertise (in medicine, law, engineering, research) — A specific combination of knowledge and judgment: knowing a lot about a domain combined with the ability to apply that knowledge to specific situations in ways that require contextual sensitivity, ethical reasoning, and the integration of multiple considerations. AI is clearly affecting the knowledge component of expertise; the judgment component remains more distinctly human.
Expertise — in medicine, in law, in engineering, in research — has historically been defined by a specific combination of knowledge and judgment: knowing a lot about a domain combined with the ability to apply that knowledge to specific situations in ways that require contextual sensitivity, ethical reasoning, and the integration of multiple considerations.
AI is clearly affecting the knowledge component of expertise. If an AI assistant can survey the medical literature on a specific condition more comprehensively than any human physician, can identify relevant treatment options that a physician might have missed, and can flag drug interactions and contraindications automatically, the specific knowledge advantage that medical expertise provides is partially shared by anyone with access to the AI.
But knowledge and expertise are not the same thing. Expertise is not just knowing things — it is knowing how to apply things, when to apply them, and what to do when the standard approaches don’t work. A physician with deep clinical experience knows things about how patients respond to treatment, how symptoms present in specific patient populations, how to read a patient’s facial expression and body language for information not captured in the chart — things that are not in the AI’s training data and that AI cannot replicate.
The partial encroachment of AI on the knowledge component of expertise changes the distribution of value within professional domains. The activities where expertise adds value relative to AI — those that require contextual judgment, relationship skills, ethical reasoning, and adaptation to situations that do not fit the standard pattern — become more valuable relative to the activities where AI can substitute for expert knowledge.

The activities where expertise adds value relative to AI — those that require contextual judgment, relationship skills, ethical reasoning, and adaptation to situations that do not fit the standard pattern — become more valuable relative to the activities where AI can substitute for expert knowledge.
This has specific implications for professional education and professional practice. The education of physicians, lawyers, and engineers has traditionally spent significant time on knowledge acquisition — learning the basic science, learning the law, learning the engineering principles. If AI can provide much of this knowledge on demand, professional education might invest more time in the judgment, relationship, and ethical dimensions that AI cannot replicate.
Whether this reallocation actually happens — whether professional education can and will adapt to the AI era in ways that serve the public well — is an empirical question that will be determined by specific decisions in specific institutions over the next decade.
The Epistemic Dependency: What Happens When We Outsource Knowing
One of the deepest concerns about AI’s cognitive impact is what might be called epistemic dependency — the risk that humans become so reliant on AI for knowledge and reasoning that they lose the capacity for independent epistemic agency.
Epistemic agency — The ability to form beliefs, evaluate evidence, reason through problems, and reach conclusions independently. Epistemic agency is fundamental to what it means to be an autonomous person. A person who can only believe what they are told, who cannot evaluate evidence on their own, who is incapable of independent reasoning, is in a specific sense not fully autonomous, even if their beliefs are produced by a reliable source.
Epistemic agency — the ability to form beliefs, evaluate evidence, reason through problems, and reach conclusions independently — is fundamental to what it means to be an autonomous person. A person who can only believe what they are told, who cannot evaluate evidence on their own, who is incapable of independent reasoning, is in a specific sense not fully autonomous, even if their beliefs are produced by a reliable source.
AI assistants raise the concern that they could, if relied upon too heavily, erode epistemic agency. A person who always asks the AI what to believe and always accepts the AI’s answer is in a situation structurally similar to a person who always accepts the authority of a specific information source without independent evaluation.
The concern is not hypothetical. There are documented cases of people accepting AI-generated misinformation as true because the AI presented it confidently. There are documented cases of people changing their beliefs on consequential topics based on AI outputs without any independent verification. The hallucination problem in language models means that AI systems confidently assert false things, and users who do not independently verify AI outputs will sometimes believe false things because they trusted the AI.

The hallucination problem in language models means that AI systems confidently assert false things, and users who do not independently verify AI outputs will sometimes believe false things because they trusted the AI.
The appropriate response to epistemic dependency is not to avoid AI assistance but to develop the specific meta-cognitive skills that allow people to use AI assistance without losing epistemic agency. These skills include: recognising when an AI output should be verified independently; understanding the specific failure modes of AI systems (hallucination, training cutoff, domain limitations); developing the capacity for critical evaluation of AI outputs; and maintaining the independent reasoning capacities that allow evaluation of AI-generated conclusions.
The meta-cognitive skills that allow people to use AI without losing epistemic agency:
- Recognising when an AI output should be verified independently — knowing the categories of question (factual claims, legal advice, medical information, historical accounts) where AI hallucination risk is highest and where independent verification matters most
- Understanding the specific failure modes of AI systems — hallucination, training cutoff, domain limitations, the tendency to produce plausible-sounding but false citations and statistics
- Developing the capacity for critical evaluation of AI outputs — the ability to ask “how would I know if this were wrong?” and to apply that question to AI-generated answers
- Maintaining the independent reasoning capacities that allow evaluation of AI-generated conclusions — the capacities that would be lost if outsourced indefinitely to the AI
These meta-cognitive skills are not different in kind from the critical thinking skills that have always been part of education, but they have specific applications to AI interaction that require explicit development.
The Cultural Dimension: What AI Does to Collective Knowledge
The impact of AI on knowledge is not just individual — it is collective. The way a society stores, transmits, and develops knowledge is a cultural phenomenon, and AI is changing those cultural dimensions of knowledge.
The canon question. Cultural knowledge is not just individual facts — it is shared references, shared stories, shared aesthetic experiences, shared values. The cultural canon — the set of texts, images, and experiences that a culture considers important and that educated members of that culture share — has been transmitted through specific institutions: schools, libraries, museums, publishing houses.
AI assistants change the relationship to the cultural canon. A person who has never read Hamlet but has asked an AI to explain it knows something about Hamlet — but their knowledge is different from the knowledge of someone who has read it, been moved by it, struggled with its language, and discussed it with others who have shared that experience. Whether the AI-mediated knowledge of Hamlet produces the same cultural common ground that direct experience of the text produces is a question about the sociology of culture that we are only beginning to have the evidence to answer.
The collective memory question. Societies maintain collective memory — shared understanding of historical events, of cultural achievements, of the experiences that have shaped the community — through specific institutions and practices. Oral traditions, printed histories, museum collections, school curricula — these are the mechanisms through which collective memory is maintained and transmitted.
AI assistants change how individuals relate to collective memory. The information is accessible in new ways, potentially to more people, in more personalised forms. But the experience of collective memory — the shared understanding that comes from having been educated in the same tradition, having read the same books, having been to the same exhibitions — may be partially lost if the experience becomes individualised and AI-mediated.
The knowledge production question. AI is not just changing how existing knowledge is accessed and transmitted — it is changing how new knowledge is produced. The scientific AI applications discussed in E24 are examples: AI systems that generate new scientific knowledge by finding patterns in data, by designing experiments, by generating hypotheses. The cultural implications of AI-generated knowledge — where does it come from, who is responsible for it, how is it integrated into the cultural tradition of knowledge — are questions that the field is still working through.
The Cognitive Offloading Research: What We Know
The cognitive science research on “cognitive offloading” — the use of external tools to extend cognitive capacity — provides a useful empirical basis for thinking about the cognitive impact of AI.
Cognitive offloading — The use of external tools (writing, calculators, search engines, AI assistants) to extend cognitive capacity — to remember more, compute faster, retrieve more reliably than biological cognition alone can. The cognitive science research on cognitive offloading provides the empirical basis for thinking about AI’s cognitive impact: each prior technology has produced both gains (in-context performance) and losses (in transferable cognitive capacity).
The research on cognitive offloading with previous technologies — writing, calculators, search engines — provides several consistent findings that are likely to extend to AI assistants.
Performance in-context improves. When cognitive tools are available, performance on tasks that the tools assist with improves. This is obvious but important: AI assistance produces better immediate outputs than no AI assistance, in most contexts.
Learning is affected. The relationship between cognitive offloading and learning is more complex. In some contexts, cognitive offloading supports learning by reducing cognitive load and allowing attention to be directed to higher-level aspects of tasks. In other contexts, cognitive offloading substitutes for the cognitive work that is itself the learning process. Whether AI assistance with a specific task supports or substitutes for learning depends on the specific task and the specific way the assistance is used.
Metacognition matters. The impact of cognitive offloading on cognition depends significantly on metacognition — on the learner’s awareness of what they are doing and why. Learners who understand when they are offloading cognitive work and why, who monitor whether the offloading is serving their learning goals, and who actively engage with the cognitive aspects of tasks rather than passively accepting AI outputs, tend to benefit more from cognitive tools and lose less cognitive capacity.
Transfer is limited. Skills developed with cognitive tools often do not transfer to contexts where those tools are unavailable. A student who has always done mathematics with a calculator may struggle with mental arithmetic. A person who has always used GPS may struggle to navigate with a map. The cognitive capacity that is exercised when tools are used tends to be the higher-level capacity of using the tools effectively, rather than the lower-level capacity that the tools substitute for.
These findings suggest that the cognitive impact of AI will be highly contextual and highly dependent on how AI is used. AI used as a thinking partner — to challenge, to scaffold, to provide feedback — will produce different cognitive effects from AI used as a thinking substitute — to do cognitive work that the user could in principle do themselves.
The Wisdom Question: What AI Cannot Provide
There is a specific kind of knowing that AI assistants cannot provide, and that may become more rather than less important as AI becomes more capable.
- Born:
- 384 BCE, Stagira, Chalcidice, Ancient Greece
- Died:
- 322 BCE, Euboea, Ancient Greece
- Nationality:
- Greek
- Role:
- Philosopher
- Known for:
- Foundational contributions to virtually every field of ancient philosophy — including the distinction between episteme (theoretical knowledge), techne (craft knowledge), and phronesis (practical wisdom). The concept of phronesis — practical wisdom developed through experience and reflection on experience — is the framework this article uses to name what AI cannot provide.
Phronesis (Aristotle’s term; often translated “practical wisdom”) — The kind of knowing that allows a person to navigate complex, ambiguous situations with appropriate judgment; to weigh competing values; to understand what matters in a specific context for specific people; to know when rules apply and when they don’t. Phronesis is not a database of facts. It is a disposition developed through experience, reflection, and engagement with the full complexity of human life — and it is precisely what no AI trained on text descriptions of human experience can replicate.
Wisdom — the ability to navigate complex, ambiguous situations with appropriate judgment; to weigh competing values; to understand what matters in a specific context for specific people; to know when rules apply and when they don’t — is not a database of facts. It is a disposition developed through experience, reflection, and engagement with the full complexity of human life.
A physician who has sat with thousands of patients understands something about illness, about fear, about how people process difficult information, about the relationship between body and mind — that no database of medical knowledge contains and that no AI trained on medical text has learned in the same way. A judge who has presided over hundreds of cases understands something about the gap between written law and justice, about how people behave under pressure, about the texture of human motivation — that a system trained on legal text cannot capture.
This kind of practical wisdom — phronesis, in Aristotle’s term — is precisely what cannot be reduced to information processing. It is developed through lived experience, through reflection on that experience, through the kind of character formation that comes from having to make difficult choices and live with their consequences.
As AI takes over more of the information-processing and knowledge-retrieval work that has historically been part of professional expertise, the specifically human contribution to that expertise becomes more clearly visible. It is not the knowledge that the AI cannot substitute for — it is the wisdom that the AI cannot replicate.

It is not the knowledge that the AI cannot substitute for — it is the wisdom that the AI cannot replicate.
This observation has implications for education, for professional development, and for how we think about the value that specifically human expertise adds in an AI-assisted world. The education that produces wisdom — the engagement with difficult texts, the experience of making and reflecting on choices, the development of character through practice — is not replaced by AI but becomes more clearly the distinctive human contribution to cognitive life.
The New Relationship: Augmentation, Not Replacement
The most useful frame for thinking about AI’s cognitive impact is augmentation rather than replacement. AI assistants are changing what human minds can do — extending their reach, increasing their speed, reducing the friction of certain kinds of cognitive work — without replacing the specifically human cognitive activities that give life meaning.
The augmentation frame is important because it rejects both the anxiety that AI will replace human thinking and the complacency that AI will not significantly affect human cognition. Both extremes miss the reality: AI is significantly affecting human cognition, but the effect is to change what humans are needed for, not to make human cognition obsolete.
The augmentation frame is important because it rejects both the anxiety that AI will replace human thinking and the complacency that AI will not significantly affect human cognition. Both extremes miss the reality: AI is significantly affecting human cognition, but the effect is to change what humans are needed for, not to make human cognition obsolete.
The augmented human — the person who uses AI tools effectively, who maintains the metacognitive skills to use those tools critically, who has developed the wisdom that AI cannot replicate — will be different from the person without those tools. They will know more, produce more, accomplish more in less time. But the specifically human dimensions of their cognitive life — the curiosity that drives them, the values that guide them, the wisdom that contextualises their judgments — are not replaced by the tools. They are, if anything, more necessary.
The deepest consequence of the AI revolution may be this: by extending what humans can know and do, it clarifies what is distinctively, irreplaceably human about the life of the mind. Not the information processing, not the pattern recognition, not the synthesis of existing knowledge — but the curiosity that asks the question, the values that guide the inquiry, and the wisdom that interprets the answer.
The cognitive impact of AI is therefore not a threat to human intellectual life but a transformation of it — one that requires adaptation, that will change what skills are valued and how they are developed, but that does not eliminate the central role of the human mind in the project of understanding the world and living well in it.

These are the things that the memory machine cannot remember for us. They are also the things that matter most.
