[Musk said the only way to solve the U.S. national debt problem is AI and robots] On October 18, according to media reports, Musk, the world’s richest man, said in an interview with biographer Walter Isaacson that the Department of Government Efficiency (DOGE) he once led failed to solve the fiscal deficit problem from within the government, and believed that the U.S. president, both houses of Congress, and the judicial system generally lacked the will to reduce government spending. Musk said that the only way to solve the U.S. national debt problem is AI and robots, and "it cannot be solved by blind savings." He also admitted that he had stayed in the White House for too long and should have stayed more behind the scenes and returned to AI work earlier. It is reported that the complete interview will be broadcast on a new podcast hosted by Isaacson on October 20, local time.
