A study by MIT found that using AI tools like ChatGPT to help with writing tasks can lead to cognitive decline, including weakened neural connectivity, impaired memory recall, and diminished sense of ownership over one's work. The study used EEG scans to measure brain activity and found that participants who relied on AI tools showed significant changes in their brain function. The researchers suggest that over-reliance on AI can lead to a decline in critical thinking and problem-solving skills. The study's findings have implications for the use of AI in education and the workplace.
