AI's Brain Drain: Is Our Thinking At Risk?

Concerns are mounting over the potential negative impacts of artificial intelligence on cognitive health, drawing parallels to the societal and health consequences observed with the proliferation of streaming services. Just as increased screen time from streaming has been linked to sedentary lifestyles and associated chronic diseases, the widespread adoption of AI tools raises questions about the future of human intellect.

Academic institutions are already grappling with AI's influence; a 2026 survey revealed that 95% of undergraduates use AI in some capacity, with 94% admitting its use in assessed work. This coincides with declining educational attainment levels across OECD countries, with reports linking poor student performance to extended screen time and increased digitalization.

Preliminary research using EEG sensors suggests that students who use generative AI for essays exhibit weaker and less distributed brain connectivity compared to those who write independently. This finding supports the notion that a lack of mental engagement can lead to cognitive decline over time. The principle of 'use it or lose it' applies to our brains, just as it does to our muscles.

As AI capabilities advance, there is a growing concern that essential cognitive functions like thinking, reading, and problem-solving may diminish. This raises critical questions about the long-term impact on quality of life and healthy aging, potentially leading to a rise in brain-related chronic diseases. The focus remains on whether these issues will be addressed or if the drive for technological advancement will overshadow potential detrimental effects on human cognition.
