Nvidia CEO Jensen Huang said trillions of dollars more will be needed to build the energy and computing backbone for artificial intelligence.

Huang sees the AI industry as a “five-layer cake” requiring total industrial reinvention, with Nvidia’s chips a particularly crunchy part of the recipe.

"We're talking about six-figure salaries for people who are building chip factories or computer factories or AI factories," Nvidia's Jensen Huang said at WEF.
