How AI enhances productivity but weakens the mind

The convenience of Artificial Intelligence (AI) is undeniable. Yet, it raises questions about our cognitive habits. Concerns are emerging that over-reliance on AI may affect critical thinking, problem-solving, and intellectual development. What actually happens to the human brain when it no longer needs to think as hard?

In the MIT Media Lab study "Your Brain on ChatGPT," researchers observed that younger people (aged 17–25) — the same ones who often see themselves as tech geniuses — turned out to be the most vulnerable. Using EEG scans, measurable changes were detected, showing significantly lower neural connectivity in participants who used AI compared to those who worked independently.

Excessive AI use can push us into cognitive debt, a state in which neurons involved in memory, reasoning, and creativity become less active. The brain gradually prefers these "lazy" pathways because it is inherently energy-efficient. This not only impacts learning but also erodes confidence in one's intellectual ability.

When we let AI write, plan, and think for us, our neurons essentially clock out early. We may become increasingly dependent on the tool and less able to function without it. Engagement with questions like "why?" or "what if?" may decline. We risk becoming consumers of AI-generated answers rather than thinkers producing them.

The MIT team also found that AI-assisted essays were more formulaic and less original, with participants showing weaker recall of their own work. In fact, 83% could not quote a single line from essays they had just "written" with AI assistance. This phenomenon closely aligns with what psychologists term digital amnesia — the tendency to forget information easily.

The real advantage of AI lies in using it mindfully and as a complement rather than a replacement. We should deliberately start doing things ourselves, such as mental arithmetic or navigating without GPS, to maintain mental agility. Limiting time spent on AI-driven platforms that promote mindless prompting, and setting boundaries for its use in specific tasks rather than as a default, can be beneficial. In addition, taking regular breaks from digital engagement can yield noticeable benefits.
