In a blog post, Open AI said: "We will begin deploying $100 billion immediately. This infrastructure will secure American leadership in AI, create hundreds of thousands of American jobs, and generate massive economic benefit for the entire world."

"This project will not only support the re-industrialization of the United States but also provide a strategic capability to protect the national security of America and its allies," it said.
