Where did all the digital humans go? Metaverse was a worldwide syndrome, but as COVID-19 ended and outdoor activities resumed, it became a mirage. Virtual humans — who generated buzz in digital marketing, entertainment, and social media — are also fading. Virtual idols, AI anchors, and virtual influencers are faltering. By 2023, market size contracted to $14 billion as expectations turned to disappointment in an adjustment period. Virtual humans still lack nuanced emotional expression, and user fatigue increased as they proliferated everywhere. Ethical issues also remain challenges. However, generative AI technology is advancing virtual humans. In education, finance, and entertainment, virtual humans are establishing themselves as core industrial elements beyond simple trends. Virtual humans are undergoing a recalibration — refining rather than proliferating. Market trajectory: 2019 ~$10B → 2021 ~$15B peak (30% growth) → 2023 ~$14B correction → projected recovery as generative AI improves quality-to-cost ratio. Cases of virtual human applications advancing despite overall market correction: (1) Education — AI tutors providing personalized learning without human teacher cost scaling constraints; (2) Finance — Shinhan Bank's Rozy demonstrating younger customer engagement through relatable virtual brand ambassadors; (3) Healthcare — virtual health coaches and therapy assistants reducing stigma around mental health support; (4) Entertainment — fully AI-generated virtual idol Mave: and PLAVE demonstrating two strategic approaches (pure virtual vs. human-AI hybrid). The correction period is separating sustainable virtual human applications (where virtual nature provides advantages over human alternatives) from novelty applications (where the virtual human gimmick was the primary value).
