Hours after returning to the White House, President Donald Trump made a symbolic mark on the future of artificial intelligence by repealing former President Joe Biden’s guardrails for the fast-developing technology.

The order required developers of AI systems posing risks to national security, the economy, public health or safety to share the safety test results.

When Biden's AI Order was established, half a dozen US politicians applauded the measure alongside industry executives like Microsoft President Brad Smith, who called it a "critical step forward in the governance of AI technology" (In October, Microsoft founder Bill Gates quietly supported Kamala Harris for president with a $50 million donation).

U.S. President Donald Trump on Thursday signed an executive order related to AI to "make America the world capital in artificial intelligence," his aide told reporters in the White House's Oval Office.

Donald Trump axed all that yesterday as he signed a flurry of new executive orders. One of his first actions was to rescind 78 Biden-era executive actions, including Executive Order 14110 on “Safe, Secure, and Trustworthy Development and Use of Artificial Intelligence.”

One of the president's executive orders rescinded an ethics rule that would have restricted Joe Biden's appointees from certain lucrative private-sector jobs.

Much of Biden's order set in motion a sprint across government agencies to study AI's impact on everything from cybersecurity risks to its effects on education, workplaces, and public benefits.

U.S. President Donald Trump signed an executive order which revokes the Biden Administration's artificial intelligence policies and has directed the development of an AI Action Plan to boost America's AI dominance.
