🇹🇼 AI 會取代工程師嗎？一個工程師的真實觀察
「AI 會取代工程師嗎？」這大概是 2025-2026 年被問最多的問題。身為一個每天用 AI 寫程式的工程師，我想給一個誠實的答案：不會完全取代，但會大幅改變這個職業的面貌。
AI 已經能做什麼？
先承認 AI 現在的能力確實驚人：
- 寫樣板程式碼：CRUD API、表單驗證、單元測試，AI 寫得又快又好
- Debug：貼上錯誤訊息，AI 通常能準確定位問題
- 解釋程式碼：理解一個陌生的 codebase，AI 能幫你快速上手
- 重構：程式碼風格統一、效能優化，AI 做得很不錯
- 完整功能實作：給出明確需求，AI Agent 能從零實作一個功能
AI 還不能做什麼？
但 AI 也有明確的局限：
- 系統架構設計：在多個技術方案中做出正確取捨，需要經驗和判斷力
- 理解商業需求：把模糊的商業目標轉化為技術方案，AI 不太行
- 處理未知問題：真正新穎的技術挑戰，AI 沒有可參考的訓練資料
- 跨團隊協作：溝通、協調、政治手腕，這些是人的領域
- 負責任：系統出了問題，總要有人負責。AI 不會負責
真正會被影響的是誰？
不是所有工程師受到的影響一樣大：
- 高風險：只會套框架、複製貼上的初級工程師。AI 做這些比你快
- 中風險：中階工程師如果不學習使用 AI 工具，效率會被淘汰
- 低風險：懂架構、懂業務、能解決複雜問題的資深工程師
- 最低風險：能善用 AI 的任何層級工程師——AI 是你的放大器
工程師該怎麼應對？
- 擁抱 AI 工具：Cursor、Claude Code、Copilot 都要會用。不用 AI 的工程師會像不用 IDE 的工程師一樣落伍
- 往上走：培養系統設計、架構思維、業務理解能力
- 建立領域專長：AI 是通才，你要成為某個領域的專家
- 學習 AI 應用開發：理解 RAG、Agent、MCP 等 AI 原生開發模式
- 軟實力：溝通、領導、產品思維，這些 AI 取代不了
我的預測
未來 5 年：
- 工程師的需求量不會減少，但入門門檻會改變
- 一個工程師搭配 AI 工具的產出，等於現在 3-5 個工程師
- 「AI 工程師」會成為標準職稱，而不是特殊專長
- 不用 AI 的工程師會被市場淘汰
好不好用，試了才知道。與其擔心被取代，不如現在就開始學習如何跟 AI 協作。
🇺🇸 Will AI Replace Engineers? An Engineer's Honest Take
"Will AI replace engineers?" This is probably the most asked question in 2025-2026. As an engineer who uses AI to code every day, here is my honest answer: No, not completely — but it will drastically change what the profession looks like.
What Can AI Already Do?
Let's acknowledge AI's current capabilities are genuinely impressive:
- Boilerplate Code: CRUD APIs, form validation, unit tests — AI writes these quickly and well
- Debugging: Paste an error message, and AI usually pinpoints the issue accurately
- Code Explanation: Understanding an unfamiliar codebase — AI helps you ramp up fast
- Refactoring: Code style consistency and performance optimization — AI does well
- Full Feature Implementation: Given clear requirements, AI Agents can implement features from scratch
What Can't AI Do Yet?
But AI has clear limitations:
- System Architecture Design: Making the right trade-offs between technical approaches requires experience and judgment
- Understanding Business Requirements: Translating vague business goals into technical solutions — AI struggles here
- Handling Novel Problems: Truly new technical challenges where AI has no training data to reference
- Cross-team Collaboration: Communication, coordination, and organizational dynamics are human domains
- Accountability: When systems fail, someone needs to be responsible. AI doesn't take responsibility
Who Will Be Most Affected?
Not all engineers face the same level of impact:
- High Risk: Junior engineers who only follow frameworks and copy-paste. AI does this faster
- Medium Risk: Mid-level engineers who don't learn AI tools will be outpaced
- Low Risk: Senior engineers who understand architecture, business, and can solve complex problems
- Lowest Risk: Engineers at any level who effectively leverage AI — AI is your multiplier
How Should Engineers Adapt?
- Embrace AI Tools: Learn Cursor, Claude Code, Copilot. Engineers not using AI will be like engineers not using an IDE
- Level Up: Develop system design, architectural thinking, and business understanding skills
- Build Domain Expertise: AI is a generalist — become an expert in a specific domain
- Learn AI-Native Development: Understand RAG, Agents, MCP, and other AI-native development patterns
- Soft Skills: Communication, leadership, and product thinking — AI cannot replace these
My Predictions
In the next 5 years:
- Demand for engineers won't decrease, but entry requirements will change
- One engineer with AI tools will match the output of 3-5 engineers today
- "AI Engineer" will become a standard job title, not a specialty
- Engineers who don't use AI will be phased out by the market
You won't know until you try it. Instead of worrying about being replaced, start learning to collaborate with AI right now.
