Neurowissenschaftler Lutz Jäncke is calling for a complete ban on cellphones in schools, characterizing the rapid digitalization of the classroom as a “wucherndes Krebsgeschwür” (a proliferating cancerous tumor). As of June 8, 2026, the 70-year-old expert suggests that integrating artificial intelligence and digital tools into education may be fundamentally altering human cognitive development.
Did You Know? Despite his concerns about the impact of technology on the human brain, Lutz Jäncke maintains a personal appreciation for traditional, outdoor activities, noting that he enjoys golfing in rainy, “British” weather conditions.
The Risks of Digitalization in Education
Jäncke argues that the current trajectory of digital integration in schools poses significant risks to the way students learn and process information. By comparing the spread of these technologies to a disease, he emphasizes the urgency of re-evaluating how schools approach screen time and AI assistance. His perspective suggests that the focus should remain on human cognitive growth rather than reliance on machines.
Expert Insight: The debate over technology in the classroom often centers on the tension between modern efficiency and foundational learning. Jäncke’s firm stance highlights a growing movement among scholars who fear that removing the friction of traditional learning—such as manual research or memorization—could have long-term consequences on critical thinking skills.
Looking Ahead: The Future of Gen Z and AI
As the debate continues, questions remain regarding whether the current generation, Gen Z, is experiencing a measurable decline in cognitive ability compared to those before them. While Jäncke offers insights into the potential for machines to become “smarter” than humans, the implications for school policies are likely to evolve. It is possible that more educational institutions will consider restrictive cellphone policies as a direct response to these neuroscientific warnings.
