Today the OECD released the results of PISA 2025. They make uncomfortable reading. The results point to a broader challenge for education systems, including Sweden, and raise questions about whether young people are developing the fundamental competencies in mathematics, reading and science that they will need in a rapidly changing world.
At the same time, another transformation is taking place at extraordinary speed. AI has already become part of how young people learn and how we work at universities.
I think we need to consider these two developments together.
Much of the discussion about AI in universities has concerned what AI can do. How can it improve teaching? How should students be allowed to use it? Can it accelerate research? These are important questions, and at SCI we have been working actively with them in our guidance for AI in education. But there is another question that I increasingly find more fundamental:
What does it mean to become scientifically competent in the AI generation?
A student can ask AI to explain a theorem, solve an equation, write code or summarise a scientific paper. A doctoral student can use it to search literature, suggest hypotheses, analyse data or propose steps in a proof. Researchers are already experimenting with systems that automate increasingly large parts of the scientific process. This is an extraordinary opportunity for science. But it creates a paradox:
The easier it becomes to produce an answer, the more important it becomes to know how to judge the answer.
We learn to become researchers partly through struggle. A doctoral student searches the literature, writes code that does not work, follows an argument before finding the mistake, writes and rewrites, and discusses half-formed ideas with a supervisor. AI can remove much of this struggle, and some of it we should be delighted to remove. Science has always progressed by developing tools that allow us to stop doing things that machines can do better.
But some of this struggle may also be where scientific judgement is formed.
This concern is beginning to appear explicitly in the scientific discussion: AI may accelerate scientific production while narrowing scientific inquiry and affecting how expertise and judgement develop ( Nature comment, “The uncritical adoption of AI in science is alarming — we urgently need guard rails“)
This has consequences for both doctoral education and the role of the professor. If AI can perform some of the activities through which we traditionally learned to become researchers, we need to understand what can safely be delegated and what is essential to developing an independent scientist.
At the same time, AI is narrowing the traditional gap in access to knowledge and technical expertise between professor and doctoral student. What experience provides, however, may be something harder to reproduce. Which of ten plausible directions is worth pursuing? When should we abandon an approach? What result would actually change our understanding? When is an unexpected result a mistake, and when is it the beginning of something interesting?
Perhaps the professor of the AI generation will become somewhat less important as a provider of answers and even more important in helping young researchers learn how to ask questions and exercise judgement.
And this brings me back to PISA 2025. The students who will enter KTH in a few years are growing up in an environment where access to sophisticated answers is becoming almost unlimited, while we are seeing worrying signals about fundamental competencies in education.
The response cannot be to protect students from AI, nor simply to teach them to use it more efficiently. Generative AI can support learning, but should enrich it rather than replace cognitive effort or teachers’ professional judgement (The OECD Digital Education Outlook 2026)
Our responsibility as educators is therefore larger: it involves fostering curiosity, persistence and the confidence to question what a machine or, for that matter, a professor tells you. These are skills that have always been part of education, but have perhaps never been as fundamental as they are today.
The AI generation will need more scientific competence, not less.
Our challenge as universities is to make sure they acquire it.
