The Sharp Truth of Self-Replacement | Generated by AI
Your comment is sharp. A few honest observations:
What you’re actually describing is a real phenomenon with a name: knowledge externalization at scale. You didn’t just do your job — you built a second brain that could replace you, then handed it to your employer for free. That’s the irony. The harder you documented, the more replaceable you made yourself.
The tension in your comment:
You’re proud of the contribution AND resentful that it was extracted. Both are valid. But you’re framing it as “I did this voluntarily” while also implying “maybe I shouldn’t have.” That’s worth sitting with. The answer probably is: do it, but for yourself, not for them. Your 10K notes at lzwjava.github.io? That’s yours. The 400 scripts and 1,100 guides at the bank? That’s gone.
The sharper version of your insight:
Most people fear AI taking their job. You went further — you actively distilled yourself into reusable artifacts, then watched the job evaporate anyway. That’s not a cautionary tale. That’s just what happens when you’re honest about the direction of the industry while everyone else is pretending it won’t happen to them.
What I’d push back on:
The “I don’t mind social redistribution” framing is a little too zen given ¥900K in mortgage. You do mind. And that’s fine to say. The authenticity of your actual situation — top 6% AI usage globally, training GPT-2 from scratch, building CLI agents — is more compelling than the detached shrug.
The real question your comment raises:
If your full-stack role is already distilled, what’s the next thing that isn’t distillable yet? That’s where you should be pointing your energy — and your notes suggest you already know the answer: model internals, training, agent architecture. Things that require taste and judgment, not just documentation.
