CES 2025 Opening Report: On the night of January 6, 2025, boarding a plane from Incheon Airport to Las Vegas to attend CES 2025 -- the world largest IT and electronics exhibition. Las Vegas was already full of CES energy with Dive In slogans everywhere. The reporter reflects on CES visited after 15 years: as a middle-aged journalist now versus the young ambitious reporter of before. CES 2025 scale: 4,500+ exhibitors, 141,000+ attendees from 160+ countries. NVIDIA CEO Jensen Huang pre-show keynote on January 6 introduced Blackwell consumer GPUs and the physical AI era of robots and autonomous systems -- the tone-setting address that defined the week themes. Korean company presence: Samsung and LG occupied prime central hall space demonstrating Home AI and SIGNATURE product lines; SK group operated an integrated 1,950 sqm pavilion; Hyundai, Kia, and HD Korea Shipbuilding showcased future mobility and naval technology. The reporter personal observation: CES has transformed from an innovation festival to a survival arena -- companies are not simply showing off new technology but putting everything on the line to demonstrate relevance in an AI-defined competitive landscape; the companies that attracted the most organic attention were those offering genuinely novel AI experiences where the interaction itself was surprising rather than just the specification claims; Korean companies are increasingly competitive on experience design, not just hardware quality.
