The spread of artificial intelligence through human productive activities is not a uniform flood but a relentless, iterative assault on economic constraints. The pattern is dictated by a strict hierarchy: a set of fundamental technical prerequisites determines what is possible, while the ruthless logic of bottleneck economics determines what happens first.

1. The Gates of Possibility: The Atomic Prerequisites

Before any task can be touched by AI, it must pass through three non-negotiable gates. These are the physics of automation; failure at any one point makes diffusion impossible.

  The spread of artificial intelligence through human productive activities is not a uniform flood but a relentless, iterative assault on economic constraints. The pattern is dictated by a strict hierarchy: a set of fundamental technical prerequisites determines what is possible, while the ruthless logic of bottleneck economics determines what happens first.

  1. The Gates of Possibility: The Atomic Prerequisites

  Before any task can be touched by AI, it must pass through three non-negotiable gates. These are the physics of automation; failure at any one point makes diffusion impossible.

  • Context Availability: The AI must have legal and reliable access to the required digital data, documents, and tools to perform the task.

    • Example: An AI designed to assist with legal discovery can be effective because it is granted access to a specific, digitized database of case documents. However, an AI cannot automate a construction site inspection if it has no access to real-time sensor data or drone footage of the site. The raw data must be available and accessible.

  • Actionability: The AI must have the permission and the technical means (e.g., APIs) to execute actions in the real world. A read-only assistant is a tool; an agent with write-access is a transformer.

    • Example: An AI that can read your email and draft a reply is a helpful tool. But an AI that can read the email, draft the reply, access your calendar to schedule the proposed meeting, and then send the email on your behalf is a true agent. It has moved from passive suggestion to active execution.

  • Feedback Latency: The time required to validate the AI's output must be short. Rapid verification enables trust and iteration; long delays destroy the business case.

    • Example: AI-powered code generation is successful because a developer can test the suggested code snippet in seconds. If it works, it's kept; if not, it's discarded. In contrast, using an AI to design a new pharmaceutical drug is a much harder problem, as the feedback loop on its effectiveness and safety can take a decade of clinical trials.

  2. The Logic of the Attack: Bottleneck Economics

  Among the universe of tasks that are technically possible to automate, limited capital and attention are not deployed randomly. They flow to points of maximum leverage, defined by two targets:

  1. System Bottlenecks: These are stages in a value chain that constrain the entire system's output and profitability. Applying AI here yields a disproportionate return by unlocking the capacity of the whole process.

     • Example: In e-commerce, the bottleneck is often not manufacturing but logistics—specifically, the "last mile" delivery. An AI that optimizes delivery routes in real-time based on traffic, vehicle capacity, and delivery windows doesn't just speed up one truck; it increases the throughput of the entire delivery network, allowing for more sales and higher customer satisfaction.

  2. Simplicity Targets: These are tasks that, while not necessarily systemic bottlenecks, are so easy and cheap to automate that they offer an immediate and undeniable efficiency gain.

     • Example: Automating the transcription of meetings. While manual transcription isn't typically the biggest cost center for a company, AI-powered transcription services are now so accurate, fast, and inexpensive that it's an obvious and immediate productivity win, freeing up employee time for more valuable work.

  This dual-targeting model explains why AI adoption appears simultaneously strategic (solving deep problems) and opportunistic (grabbing low-hanging fruit).

  3. The Pattern of Spread: The Cascading Effect

  AI diffusion is a dynamic and self-perpetuating process. The solving of one bottleneck does not end the process; it merely reveals or creates the next one. This creates a cascade that drives AI adoption relentlessly through an organization and industry.

  A clear example can be seen in customer service:

  • Step 1: An AI chatbot is implemented to handle common, repetitive customer queries (a simplicity target), freeing up human agents' time.
  • Step 2: The new bottleneck becomes the agents' ability to quickly resolve the complex, escalated issues that the chatbot couldn't handle.
  • Step 3: This creates demand for a new AI tool that provides real-time information and solution suggestions to the human agent during the call, augmenting their decision-making.
  • Step 4: As agents become more efficient, the new bottleneck might become the quality assurance process for their interactions. This leads to the adoption of AI-powered sentiment analysis to automatically score and review call transcripts.
  • This cycle repeats, continuously pulling AI deeper into the value chain, from a simple chatbot to an integrated support ecosystem.

  4. The Evolutionary Stages of Impact

  This dynamic creates a three-stage evolutionary pattern, defined by the nature of the bottlenecks being addressed.

  • Stage 1: Local Optimization (Attacking Task Bottlenecks)

    • Focus: AI is deployed as a point solution to automate isolated, routine cognitive tasks—the most obvious simplicity targets and local constraints.
    • Example: A marketing department uses an AI tool to generate social media copy. A finance department uses AI to categorize expenses. A software team uses an AI assistant to write unit tests. Each is a discrete task being optimized in isolation.
    • Brutal Reality: This phase hollows out entry-level knowledge work, targeting tasks, not jobs, and breaking traditional career progression models. The junior analyst who used to spend their first year manually categorizing transactions now finds that task automated.

  • Stage 2: Workflow Integration (Attacking Process Bottlenecks)

    • Focus: As individual tasks are optimized, the handoffs between them become the new system bottlenecks. This forces the adoption of AI agents with "Actionability" to orchestrate entire workflows from end to end.
    • Example: Instead of just generating ad copy, an integrated AI agent now takes a marketing brief, generates the copy and images, creates campaign variations for different platforms, allocates a budget based on performance predictions, and pushes the campaigns live via API—all with human oversight rather than manual execution at each step.
    • Brutal Reality: This phase makes static job descriptions obsolete. The critical human skill shifts from doing the work to designing and overseeing automated systems. Organizational inertia becomes the primary barrier to competitiveness.

  • Stage 3: Value Chain Creation (Attacking Market Bottlenecks)

    • Focus: AI capability advances to the point where it can solve problems previously considered impossible or too costly, breaking fundamental constraints of a market. This does not just optimize the existing value chain; it enables the creation of entirely new ones.
    • Example: Personalized medicine. Historically, developing a drug tailored to an individual's unique genetic makeup was economically and scientifically unfeasible. AI is now making it possible to analyze massive genomic datasets and simulate molecular interactions at a scale that allows for the creation of bespoke treatments. This isn't just a better pharmacy; it's an entirely new approach to healthcare.
    • Brutal Reality: This is the phase of true transformation. Companies that only used AI to optimize their old business model will be made irrelevant by new entrants who build their entire value chain around AI's new capabilities.

  人工智慧在人的生產活動中的擴散不是均勻的洪水，而是一種持續、不停迭代、針對經濟限制的攻擊。其模式遵循嚴格的階層：一組基礎技術前提決定了什麼是 可能的，而瓶頸經濟學的殘酷邏輯決定了什麼會 先發生。

  1. 可能性的門檻：原子級前提條件

  在任何任務能被 AI 介入之前，它必須通過三個不可協商的門檻。這些是自動化的物理法則；任何一項不成立，都會讓擴散變得不可能。

  • Context Availability（情境可獲取性）：
    AI 必須合法且可靠地取得完成任務所需的數位資料、文件或工具。

    • Example： 用於協助法律取證的 AI 可以發揮效果，因為它能存取特定、已數位化的案件文件資料庫。然而，如果一個 AI 無法取得施工現場的即時感測數據或無人機影像，它就無法自動化工地巡檢。原始資料必須存在且可取得。

  • Actionability（可執行性）：
    AI 必須擁有權限與技術手段（例如 API）來 執行 對現實世界的動作。只能讀取的工具是 assistant，而能執行動作的才是 agent。

    • Example： 能讀取電子郵件並草擬回覆的 AI 是個有用的工具。但若 AI 能讀取郵件、草擬回覆、存取你的行事曆安排會議，並替你發送郵件，那它才是真正的 agent——它從被動建議進化到主動執行。

  • Feedback Latency（回饋延遲）：
    檢驗 AI 輸出正確性的時間必須足夠短。快速驗證能建立信任與迭代；延遲過長則會摧毀商業價值。

    • Example： AI 產生程式碼能成功，是因為開發者可以在數秒內測試程式片段。能用就留下，不能用就丟掉。相比之下，用 AI 設計新藥非常困難，因其效果與安全性的回饋迴路可能要花十年的臨床試驗。

  2. 攻擊邏輯：瓶頸經濟學

  在所有 技術上可自動化 的工作中，有限的資本與注意力並不會隨機分配，而是流向 槓桿最大的位置：

  1. System Bottlenecks（系統瓶頸）： 這些是會限制整個價值鏈產出與獲利的階段。在此部署 AI 能帶來不成比例的回報，因為它解鎖了整個流程的能力。

  • Example： 電商的瓶頸通常不是製造，而是物流，尤其是「最後一哩路」。AI 用即時交通狀況、車輛容量、時段需求來最佳化路徑，不只是加速一台車，而是提升整個配送網路的吞吐量。

  1. Simplicity Targets（簡單目標）： 這些任務不一定是系統瓶頸，但因為 極度容易自動化、具立竿見影效益，所以最先被處理。

  • Example： 自動會議逐字稿。手動轉錄不是公司最大成本，但 AI 轉錄如此準確、快速、便宜，是顯而易見的效率提升。

  這個雙目標模型解釋了為什麼 AI 擴散同時看起來很 策略性（解決核心問題） 又很 機會主義（撿現成易做的）。

  3. 擴散模式：級聯效應

  AI 擴散是動態且自我延展的。解決一個瓶頸不是結束，而是讓下一個被看見或生成。這造成級聯效應，推動 AI 持續深入組織與產業。

  客戶服務是典型案例：

  • Step 1： AI chatbot 處理常見、重複問題（簡單目標），釋放人類客服時間。
  • Step 2： 新瓶頸變成客服處理複雜問題的能力。
  • Step 3： 產生需求：提供客服 即時建議 的 AI 輔助工具，提升決策效率。
  • Step 4： 當客服效率提升後，新瓶頸變成品質保證流程 → 導入情緒分析與自動評分系統。
  • 然後循環再來，AI 從聊天機器人一路滲透到全套客服支援生態系。

  4. 影響的演化階段

  這種動態產生三階段演化模式，依據所攻擊的瓶頸層級來分類：

  • Stage 1：Local Optimization（攻擊任務瓶頸）

    • Focus： 以點狀解決方案自動化個別例行認知任務——簡單目標與局部限制。
    • Example：
    • Marketing 用 AI 生成社群文案
    • Finance 用 AI 分類費用
    • Software team 用 AI 寫 unit tests 每一件都是獨立任務的局部優化。
    • Brutal Reality： 這階段侵蝕初階知識工作。AI 攻擊的是任務，不是工作，打破傳統職涯成長階梯。

  • Stage 2：Workflow Integration（攻擊流程瓶頸）

    • Focus： 當個別任務被最佳化後，任務之間的交接 變成瓶頸，因此企業不得不採用具 Actionability 的 AI agents 來編排端到端工作流程。
    • Example： 不再只是生成廣告文案，而是：
    • 讀 brief → 生成文案與圖片 → 建立不同平台版本
    • 根據預測分配預算 → 透過 API 推送 campaign 全程 AI 執行，人類只做 oversight。
    • Brutal Reality： 固定的工作描述消失。 核心人類技能從「做事」轉變成「設計與監督自動化系統」。 企業的惰性將成為淘汰原因。

  • Stage 3：Value Chain Creation（攻擊市場瓶頸）

    • Focus： AI 打破整個市場的根本限制，不只是優化現有價值鏈，而是 創造全新的價值鏈。
    • Example： 個人化醫療（Personalized medicine）。 過去，根據個人基因訂製藥物在經濟與技術上皆不可行；AI 可以分析巨量基因資料並模擬分子交互，使定製療法變得可能。 這不是「更好的藥局」——是 新的醫療模式。
    • Brutal Reality： 這階段帶來真正的顛覆。 只使用 AI「優化舊模式」的公司，會被 以 AI 為基礎重建價值鏈的新創 徹底消滅。
