In an increasingly digital world, artificial intelligence (AI) has become an essential part of everyday life, taking on increasingly complex tasks. However, the ability of these technologies to alleviate our intellectual effort raises questions about their impact on our cognitive abilities. Could the systematic use of these algorithms for various activities, from preparing a presentation to planning a route, make our brains fragile and captive to this technological crutch? Recent research and concerns expressed by intellectuals suggest that this massive outsourcing of mental work could be a double-edged sword. In a world increasingly integrated with artificial intelligence, the question of cognitive dependence arises. Performing complex tasks with the help of algorithms has become commonplace. However, we must ask ourselves whether this constant support threatens our ability to think independently. This article explores the impacts of AI use on our brains and considers whether this technology leads to a « cognitive debt. » The Growing Role of Artificial Intelligence Artificial intelligence applications are now essential for many everyday activities, from writing school papers to planning vacation itineraries, not to mention comparing bank loan offers. By relying on these technologies, we delegate a significant portion of our intellectual activity to machines, raising concerns about the impact on our brains.Scientific Concerns Researchers are worried about the consequences of using « digital crutches » on our cognitive activity. In his book « The Desert of Ourselves, » Researchers are concerned about the consequences of using « digital crutches » on our cognitive activity. “,” the philosopher Eric Sadin warns against the gradual substitution of technological systems for one of our fundamental faculties: the production of language.
Sadin even calls for a “civilizational battle” against the evolution of AI, which could diminish our personal intellectual engagement.Studies on Cognitive Impact The MIT Media Lab conducted a study in 2025, evaluating the writing ability of three groups of people with different levels of assistance: relying solely on their brain, using a search engine, or relying on AI such as ChatGPT. The results showed that AI assistance leads to poor information retention, with users unable to quote passages shortly afterward.
“Cognitive Debt”: A Difficult Return to NormalThe results of this same study also point to a “cognitive debt” generated by the frequent use of generative AI. This debt manifests itself in the difficulty users have returning to a standard level of brain activity to perform tasks unassisted. Rich and autonomous cognitive activity thus appears to be compromised by the intensive use of these tools.
Towards a reformulation of the intellectual process
Eric Sadin quotes Paul Valéry: « The lion is made of assimilated sheep. » We become intellectually stronger when we learn from others and integrate their thoughts into our own reasoning. The culture of synthesis and reflection could then suffer if we simply compile passive answers mechanically produced by AI, without genuine appropriation.
