AI가 이미 자기계발 논픽션 책을 죽였나?

LLMs like Claude and ChatGPT are displacing self-help publishing by replacing books as the primary interface for on-demand advice—Tim Ferriss's catalog is down 46% YoY, and industry-wide self-help sales fell 26.3% in Q1 2026. This isn't gradual market competition but format obsolescence: when chatbots offer instant, personalized answers for free, books functioning as lookup tables or decision trees lose their value proposition. Only books delivering irreplaceable narrative, voice, and experiential wisdom have staying power in an AI-mediated information landscape.
