“If you go out long enough, assuming theres a continued improvement in AI and robotics, which seems likely, the money will stop being relevant at some point in the future,” Musk said. He added that there will still be constraints on power, such as electricity and mass. “The fundamental physics elements will still be constraints, but I think at some point currency becomes irrelevant,” Musk said.

The forum was designed to “bring together visionaries, leaders, and change-makers shaping the future of global investment,” according to the event website. Topics ranged from AI and energy, to healthcare and finance.

Musk was joined by Abdullah Alswaha, Saudi Arabias communications minister, and Jensen Huang, chief executive officer of Nvidia Corp., as they discussed SpaceX reusable rockets, humanoid robots and AI factories. President Donald Trump also spoke at the forum, making an appearance with Mohammed bin Salman, the crown prince and prime minister of Saudi Arabia, who the president hosted at the White House on Tuesday. Musk, the CEO of Tesla, previously met with bin Salman in May at the U.S.-Saudi Investment Forum in Riyadh.
