Shockwave of AI Vibe Coding, What Is the SI Industry Survival Strategy: What Disappears Is Keyboard Labor, What Remains Is Responsible Design and Operation: The era of AI-based vibe coding has begun. Service development no longer starts from long complex specifications and multiple meetings. Just present the intention of what kind of service is needed with a few examples and conditions, and AI produces design, screen drafts, basic code, and test scenarios at once. Planning-development-verification are no longer a separated linear process but woven as one flow in a canvas-type workspace where documents, code, and execution results are visible simultaneously. This change shakes the roots of the traditional SI (System Integration) industry. Traditional SI companies have calculated project costs based on person-months (man-month) -- the amount of human labor invested. The SI industry transformation: as AI can now produce initial code drafts for standard enterprise applications, the value of SI companies can no longer be person-months of coding; the value must shift to system architecture design, security review, integration expertise, and operational responsibility; SI companies that successfully transition will position as responsible design and operation partners rather than coding labor suppliers; those that try to maintain person-month billing in a world where AI can produce equivalent output at near-zero marginal cost will face structural margin compression.
