The Complete Guide for Engineers in the AI Era
One Map, From Anxiety to Control
AI can write code now — so how do engineers thrive? This pillar pulls my 6 deep articles into one learning path: from the "will I be replaced?" anxiety all the way to "using AI as a tool and turning code into maintainable products." Click into any block to go deep.
The bottom line: writing code is no longer the edge — building products is
AI has changed how we write code — open Cursor or Claude Code and a feature appears from one sentence. But it's made one thing clearer too: vibe coding ships, but it can't be maintained. What's scarce shifted from "can write code" to "can decide what to build, can finish it, and can keep it running long-term."
These 7 articles map that out. Read them in order, or jump straight to the block you need most.
Not "no, relax," nor "yes, run." A breakdown of what AI can and can't do, plus 8 habits that keep your bargaining power five years out.

If you're an engineer anxious about being replaced, start at 01. If you're already building with AI and want to do it better, go to 03 and 04. If you built a product with AI but it's becoming unmaintainable, 05 and 06 are your first-aid kit. Wherever you enter, the destination is the same: make AI your tool, not your rival.
