Jensen Huang got mobbed like a rock star at Taiwan's biggest tech show this month. Then he walked over to SK Hynix's booth, picked up a marker, and scribbled "Please make more" on one of their memory wafers.
It was half a joke. The other half is that Nvidia's supply chain can't keep up.
For two years, the AI story has been a Nvidia story. That's starting to change.
Hundreds of billions of dollars are flowing into data centers, and demand for the parts inside them - chips, memory, wiring, power systems - is racing past what suppliers can build.
Most of those suppliers sit in Taiwan and South Korea, where few American investors have ever heard of them. That's shifting fast.
"This was a boring industry that no one cared about," UBS semiconductor analyst Timothy Arcuri said. "Now it's become the most critical infrastructure for the world."

The AI conversation has been about processing power for years - the chips that do the thinking. Nvidia owns that side.
But AI models have gotten so big that holding the information they're working with matters as much as crunching it. That's memory - exactly what Huang was asking SK Hynix to make more of.
Think of it like this: the chip is the brain, the memory is the desk it works on. The brains have gotten faster than the desks can hold paper.
That shift is changing who matters in the supply chain. South Korean memory makers and the Taiwanese firms that package these chips together are suddenly some of the most important companies in tech.
Watch the memory makers. When the CEO of the world's most valuable company is publicly asking a supplier to make more, the squeeze isn't subtle.
The AI buildout was supposed to make Nvidia the bottleneck. It turned out to be everyone behind Nvidia.
