Ex-Amazon SDE × Amazon PM: AI Writes My Code, and I Can't Explain It

Two people who both wrote documents at Amazon, one still there as a PM, one now a programmer somewhere much faster, talking about what AI changed about thinking. Not "AI will take your job." Something narrower and, I think, more real: the month you used to spend figuring a system out was also the month that trained you. AI gives you the solution on day one. The output is the same a month later. The training is gone. Recorded as a normal conversation, lightly edited. Chinese audio, English subtitles. 一个还在 Amazon 做 PM，一个在 Amazon 写过代码、现在换到一家迭代极快的公司。我们聊了 16 分钟，从「为什么脑子清楚但一被问就说不明白」，一路聊到「AI 把那张图拿走了」。 不是 AI 会取代你那种话题。是一个更窄也更真实的问题：以前你花一个月 figure out 一个系统，那一个月同时也在训练你。现在 AI 第一天就把方案给你了，一个月后结果一样，但训练没有了。 Chapters 0:00 高光预告 Highlights 0:13 开场：表弟的问题 1:31 能做好 ≠ 能讲明白 2:59 不是不会写，是没想清楚 5:19 讲给谁听 6:26 方案是 AI 写的 12:03 我在亚麻写文档的时候 12:58 这些细节值不值 13:57 不要怕丢脸
