A 26,000-student study shows AI's hidden learning cost takes two full years to surface
A longitudinal study of 26,000 students reveals that AI-assisted homework leads to a 24% decline in exam performance over two years.
Researchers found that while AI tools like DeepSeek and Qwen help students complete assignments faster and achieve higher grades initially, the long-term impact is a significant degradation in core competency. The study suggests that short-term metrics fail to capture the cognitive atrophy caused by over-reliance on LLMs for academic tasks.
