While ambitious, the $950 billion deals carry significant risks that deserve scrutiny. The semiconductor industry is notoriously cyclical, with boom-and-bust cycles that have burned even well-capitalized players. Overcapacity in memory and foundry markets could lead to price crashes, eroding profitability. Both Samsung and SK Group already carry substantial debt, and this additional spending may strain their balance sheets if demand softens.
Critics also warn of economic imbalance. Concentrating such massive investment in two conglomerates could stifle competition from smaller startups and deepen South Korea's reliance on a narrow industrial base. Other sectors like biotechnology, software, and renewable energy may be starved of capital and talent. The government's generous tax breaks might have been better spread across diverse industries.
Environmental costs are another concern. New chip fabs consume enormous amounts of water and energy, even with efficiency measures. Local protests have already emerged over potential strain on water resources. The companies' pledges to go green are commendable but may not fully offset the ecological footprint.
Finally, the geopolitical dimension adds uncertainty. US-China tensions could restrict technology transfers or market access, undermining the investment thesis. If the AI boom fizzles or shifts toward different architectures, the $950 billion could become a costly white elephant. A more cautious, phased approach might yield similar benefits with less risk.
