TOKYO - Nvidia Corp. CEO Jensen Huang said Wednesday that investment in artificial intelligence is a long-term business strategy driven by robust demand, dismissing concerns that the spending race could turn the technology boom into a bust.

"We are a long way from AI bubble," the top executive of the U.S. AI chipmaker told reporters in Tokyo, adding that "the demand is incredibly strong."

"We have to build infrastructure for at least a decade," he said. Huang is in Tokyo for corporate events.

As for Japan's potential ability to develop physical AI, technology that enables robots and other devices to operate autonomously, Huang said, "This is the moment for Japan because...Japan has historically been very good at precision manufacturing and very large-scale manufacturing."

The CEO said AI could help Japan address a severe labor shortage.

"With automation, with AI and robotics, you could augment the workers you have and increase the national productivity," he said.

The Japanese government is promoting the development of domestic AI as part of its drive to ensure national security and data protection.

Huang said, "The nation's intelligence must be nurtured, enhanced, developed here in the country," adding that Nvidia is set to make "announcements" related to sovereign AI later in the week.
