WHAT DOES OPENAI REALLY WANT FROM TRUMP?

OpenAI's proposal to the White House seeks to bypass state AI laws like California's SB 1047 by leveraging federal trade laws against China and requesting significant AI infrastructure investments. With nearly 900 state AI bills under consideration, OpenAI argues that diverse state regulations could cause chaos, while a lack of federal framework leaves the industry vulnerable. Critics point out the absence of a national governance model in OpenAI's plan, which relies heavily on national security concerns to advance its agenda.
