Only a few years ago memory prices had collapsed, inventories had swollen, and Samsung Electronics and SK hynix were enduring a brutal downturn alongside the rest of the slowing global economy.
Then the AI era rewrote the board almost overnight. The generative-AI surge that followed ChatGPT sent data-center and AI-server investment soaring, and machines built to think like humans demanded a different order of memory altogether — faster, denser, and unlike anything ordinary DRAM could deliver.
That demand has a name: high-bandwidth memory, or HBM. The AI industry today orbits Nvidia, yet inside Nvidia's beating heart sits Korean memory. If America supplies the platforms and the software of the age, Korea supplies its memory. Small wonder the market now speaks of a semiconductor supercycle unlike any in four decades.
And yet this is precisely the moment for cold clarity, because prosperity has always clouded human judgment. Korea has a habit of treating whichever industry happens to be surging as if it were the country's permanent destiny — heavy and chemical industries in the 1970s, shipbuilding and steel in the 1980s, IT and chips in the 1990s, real estate and construction in the 2000s, and more recently the fevers around platforms and batteries. Each time, a single sector was mistaken for the fate of the whole nation.
But the history of industry has always been a history of cycles. Booms breed overinvestment; overinvestment breeds oversupply; oversupply ends in collapsing prices and painful restructuring. That is the cold, repeating logic of industrial capitalism, and semiconductors are no exception.
In the 1980s, Japanese chipmakers nearly owned the memory market, and the world declared the future Japanese. Then bubbles burst, structures shifted, and American pressure bore down, and Japan's lead unraveled. Korea inherited that crown — Samsung rising to dominance, SK Hynix to world rank — but never on a smooth road. The industry survived countless slumps, price crashes, and financial crises. That survival is exactly why this moment matters most: the boom is the dangerous hour.
The dispute now roiling Korean society looks like a quarrel over wages, but it runs far deeper. Labor, management, politicians, and the financial markets are colliding over how to divide record profits. Workers say the record was built on their devotion; shareholders insist the earnings of a listed company belong, first, to its owners; politicians invoke a third logic entirely — that chips are a national strategic asset.
The trouble is that all three claims have begun to collide, because the semiconductor has quietly stopped being a mere industry. It is at once an export engine, a security asset, the gravitational center of the stock market, and the vessel of the country's youthful ambition. At some point it began to be treated as if it were the nation itself.
That is where the danger I would call the "semiconductor disease" begins. Economists speak of the Dutch Disease — the way one overpowering sector can warp an entire economy out of balance, named for how a natural-gas boom hollowed out Dutch manufacturing. Korea now faces its own variant.
The Korean stock market has, in effect, become the semiconductor market: when Samsung and SK hynix rise, the whole index rises; when chips wobble, the whole economy shakes. Over the long run that is not a healthy structure. Once a nation leans this heavily on a single sector, that sector's cycle becomes the nation's fate.
Why hardware is not enough
The deeper issue is the nature of the AI era itself. People speak as if AI will grow forever, but technology has never moved that way. The dot-com bubble, the LCD industry, solar power, batteries — each rode its own vast cycle. AI, too, will meet oversupply, price wars, shifting standards, geopolitical risk, and China's pursuit.
The China variable is decisive. Even under American sanctions, Beijing is pouring national resources into building a self-sufficient chip ecosystem. A technology gap still exists — but the surest way to lose an industrial war is to underestimate how fast a rival is closing it. Japan chased America; Korea chased Japan; China now chases Korea. This battlefield has no permanent victor.
Nor will the contest stay confined to memory. The competition ahead will be an ecosystem war binding chips to energy, software to cloud, data centers to robotics, AI platforms to defense and quantum computing. Korea holds the world's finest memory technology, but memory alone cannot guarantee the future.
The real winner of the AI age will not be whoever makes the best chip; it will be whoever commands the whole ecosystem. America's strength is not Nvidia alone but OpenAI and Microsoft, Google and Amazon, Meta and Tesla — platform, cloud, data center, and software woven into one fabric. Korea remains far too hardware-centric.
So the question Korea must truly wrestle with is not how to split this year's profits. It is how to prepare next-generation AI architecture, breakthroughs in power efficiency, AI software and data sovereignty, talent, a place in the reordered global supply chain, industrial diversification, and an energy strategy.
Power, above all, is decisive: AI data centers devour electricity, which is why America's tech giants now scramble for nuclear, LNG, and renewables. Chip competitiveness will increasingly mean energy competitiveness.
Three great transitions are moving at once — the AI revolution, the U.S.–China contest for supremacy, and the remaking of energy and supply chains — and the semiconductor sits where all three axes meet. America sees chips as a matter of security, China as a matter of survival, Europe as a cause worth vast subsidy. The semiconductor has become a strategic asset of modern civilization.
Which is all the more reason to stay cold-eyed. The crisis begins the moment one grows drunk on the boom. 居安思危 — in times of peace, think of danger. Korea's chip industry sits at the very summit of the world; paradoxically, that may be its most perilous moment. History has never long tolerated the arrogant victor. The industries that survive are never the ones intoxicated by today's boom, but the ones that prepared for tomorrow's crisis.
What is needed now is not applause but a clear strategy. Labor must think in terms of long-term competitiveness; companies must build the future ecosystem rather than chase quarterly results; government must weigh the whole structure of national industry above political popularity. Above all, balance. The semiconductor is Korea's core strategic industry — but it must not become a "semiconductor disease" that swallows the nation whole.
The AI era has only just begun, and Korea stands in the middle of a vast historical turn. The countries that endure are not those drunk on present success but those preparing for future crisis. Let the chip be a source of national pride — and let Korea, at the same time, prepare for a future that reaches beyond it. That is the true national strategy, and the condition of survival in the age of AI.
