An MIT study indicates heavy ChatGPT use may weaken memory, lower brain activity, and replace critical thinking, leading to “cognitive debt”. EEG data revealed reduced neural connectivity and brain engagement in AI users, who also struggled with recall (83.3% couldn’t remember AI-generated work) and produced “soulless” essays. Conversely, unaided thinkers showed higher cognitive engagement and creativity. This preliminary, pre-peer-reviewed study of 54 participants raises urgent educational concerns about AI’s impact on brain development.
