Nature研究：AI可能削弱专业人员硬技能

New nature published study: AI may save time, but early evidence suggests it can weaken the hard skills professionals rely on.

In a Polish colonoscopy study, experienced endoscopists’ unaided adenoma detection fell from 28.4% to 22.4% after AI was introduced into their workflow.

That does not mean AI made doctors careless overnight.

The deeper problem is that skill is maintained by friction: looking, judging, doubting, correcting, and staying mentally answerable for the next move.

When the machine starts flagging the abnormal patch, the human eye can begin to change its job from searching to confirming.

The same pattern shows up in software: in a 2026 randomized study, AI helped some developers complete tasks, but heavy delegation weakened conceptual understanding, code reading, and debugging skill.
