Elon Musk warned the biggest issue hampering AI advancement in the United States is a problem Chinese competitors don’t have.

In a conversation in Davos, Switzerland, with BlackRock CEO and World Economic Forum interim chair Larry Fink, Musk said AI chip production is increasing exponentially, but electricity is slow to being made available, hampering the efficiency of AI data centers training and deploying AI models.

“I think the limiting factor for AI deployment is fundamentally electrical power,” Musk said. “It’s clear that we’re very soon—maybe even later this year—we’ll be producing more chips than we can turn on.”

The U.S. has been grappling with an outdated grid system, as the result of decades of underinvestment and an aging infrastructure. As tech companies increasingly rely on grid operators for electrical power, reliability issues and production limitations have threatened the speed of AI implementation, raising investor concerns of an AI bubble, as well as resignation the U.S. has already lost the battle with Chinese tech.

Two massive data centers in Nvidia’s Santa Clara, Calif., hometown may sit empty for years waiting for electricity to power them, according to energy experts. Meanwhile, the massive increase in demand, combined with the need for updated infrastructure, have driven up electricity bills for the average American.
