Sam Altman, CEO of OpenAI and creator of ChatGPT, said at the World Economic Forum in Davos that future artificial intelligence will require breakthroughs in energy because the power consumption of AI will far exceed people's expectations. He believes that energy sources that are more favorable to climate change, especially nuclear fusion or cheaper solar energy and energy storage, are the direction of AI development. He said, "Without breakthroughs, this goal cannot be achieved." "This prompts us to increase investment in nuclear fusion." In 2021, Altman personally provided $375 million to the private US nuclear fusion company Helion Energy, and the company subsequently signed an agreement to provide energy to Microsoft in the coming years. Microsoft provides computing resources for OpenAI. Altman said he hopes the world will also accept nuclear fission as an energy source.
