A recent survey of U.S. health workers found 70% of nurses and 77% of physicians fear their skills will fade as AI assistance expands. Researchers label the trend AI deskilling, arguing that reliance on machine cues could undermine decades of training. The anxiety spans medicine, computer science and other knowledge‑intensive fields.

In Poland, endoscopists who routinely performed over 2,000 colonoscopies saw their adenoma detection rate drop from 28.4% to 22.4% when the AI system was unavailable. The study, published in The Lancet Gastroenterology and Hepatology, suggests that even seasoned clinicians lose acuity after brief exposure to real‑time AI guidance.

A separate experiment by Anthropic assigned 52 software engineers a basic coding task, half with an AI assistant. Those who used the AI scored 50% on a post‑task quiz, versus 67% for the control group, and struggled most with error‑diagnosis questions. The results highlight a widening gap between performance and learning as generative AI becomes commonplace.
