Rohan Paul@rohanpaul_ai · X一项发表于《自然》的研究指出，AI虽能节省时间，但可能削弱专业人士依赖的硬技能。波兰结肠镜研究显示，引入AI工作流后，有经验内镜医师独立操作的腺瘤检出率从28.4%降至22.4%。AI并非让人瞬间疏忽，而是改变了技能培养的“摩擦”机制——从主动搜索变为被动确认。类似现象也出现在软件开发中：一项2026年随机研究发现，AI辅助虽帮开发者完成任务，但过度委派削弱了概念理解、代码阅读和调试能力。
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.
