tl;dr: South Korea is committing $1 trillion to three megaprojects: $585B from Samsung and SK Hynix to double DRAM production via new fabs, $357B from SK Group, GS, and Naver for AI data centers, and a physical AI push including Hyundai's plan to mass-produce 30,000 Boston Dynamics Atlas robots annually by 2028. The plans face hurdles, including massive electricity and water demands, multi-year fab construction timelines, and pushback from Hyundai's labor union, which just approved a potential strike over robot deployment.
