1120 ET - Elon Musk says the cost of artificial-intelligence is "plummeting" year after year, adding that the current bottleneck from widely scaled AI is power generation. "I think the limiting factor for AI deployment is fundamentally electrical power," he says, during a conversation with BlackRock's Larry Fink at Davos, noting that chip production is rapidly outpacing energy production. "Maybe even later this year, we'll be producing more chips than we can turn on," he says, making an exception for China, which is producing solar energy at a clip. He says two of his companies, SpaceX and Tesla, are separately working toward building 100 gigawatts a year of solar power in the U.S., which he said could take roughly three years.
