The difference between AI-written text and human-written text — where does it show? The Writing Formula 3GO (Revised Edition) finds the answer in ''your own story.''

Writing is no longer the exclusive domain of specialists — anyone can easily create sentences using AI. However, writing that stays with readers and makes them want to read again remains distinctly human. "AI Era Writing Formula 3GO" revisits the essence of writing that doesn''t waver even in the AI era, presenting the "3GO formula" applicable to specific writing situations. This revised edition (10 years after the 2016 first edition) integrates: the author''s foundational writing strength from journalism experience; strategic writing accumulated through corporate PR, legislative relations, and policy communication; practical know-how from new business and sales strategy development; and feedback from thousands of readers. The author is currently a doctoral student at Sogang University Graduate School of Metaverse, teaching "IT Writing" at Sogang''s Communication Center during breaks. The four formulas: Ju-geun-sa (主根詞, Main Root Word), Hyeon-jang-sa-bae (現場寫排, Scene-Setting Composition), Yong-bae-seol-sa (用配設辭, Function-Configuration-Setup Phrasing), U-ja-yu (右自由, Right Freedom) — each serving as a prescription applicable to the specific writing context. The core insight: writing is not primarily a technical skill but an expressive act — the question is "what is my story, what perspective do I bring, and how do I share it with readers?" AI-generated writing is technically competent but lacks the authentic voice and lived perspective that makes human writing resonate. In an age where AI can produce acceptable text instantly, the competitive advantage of human writing lies precisely in the irreplaceable element: genuinely personal perspective and experience.
