AI的副作用，把学生变成末人
经合组织最新的 PISA 报告，给出了迄今覆盖范围最广的一批证据：从来不用、或者几乎不用生成式 AI 的学生，科学测试平均 509 分；每天都用、或者几乎每天都用的，只有 481 分——差了 28 分，按专家的换算，差不多相当于一年半的教学进度。中国一项追踪了 26,811 名中学生、历时 30 个月的研究也发现，学生用了 AI 之后，作业分数涨了 18%、写作业的时间从 64 分钟压到 45 分钟，可是闭卷月考掉了 20%，中考和高考也明显下滑，而且完整的影响要等大约两年之后才显现。这一期想讲清楚的是：AI 的副作用，不在于机器会不会犯错，而在于我们把思考的哪一部分交给了它。教室里学生用它写作业，公司里程序员用它提交代码，应用商店里一年冒出 56 万款新 App、国内一天上线 1,300 部 AI 短剧——生成的成本被打下来了，可是验证、信任和维护的成本没有跟着降。收益进了企业的报表，能力折旧却进了个人的职业生涯。
最后要回答的是一个更难的问题：如果语言模型的一次幻觉，被复制进作业、报告、代码和搜索结果，再被下一代模型学回去，它会不会变成全社会的幻觉？这一期也聊了尼采说的"末人"到底指什么样的人。我不反对这项技术，我反对的是神话这项技术。
