U.S. President Donald Trump blasted on Monday what he called a "sick conspiracy" against artificial intelligence and data centers, rejecting calls for regulation amid mounting concerns that the technology poses a threat to humankind.

The U.S. president expanded his criticism after a day earlier he also pointed to what he called "very negative forces" wanting the AI slowdown.

Trump again said the U.S. needed to keep the lead on AI to beat superpower rival China and slammed the boss of Claude-maker Anthropic, who had called for a slowdown.

"The only control or 'guardrails' that AI needs is a STRONG AND SMART (High IQ!) PRESIDENT, and the U.S.A. has that, in spades!" Trump said in a post on his Truth Social network.

Trump has pushed back repeatedly in the past week against a tide of warnings from tech bosses on the dangers of AI, saying U.S. regulation would give rival Beijing the advantage.

"There is a SICK conspiracy going on against AI and Data Centers, and the only one that is happy about it is China," Trump added in his post.

"WHOEVER WINS AI, WINS! We are leading China, and all others, and will continue to do so. Conspiracy Theorists, Treasonists, Traitors, and Leakers, BEWARE!"

Trump also attacked Anthropic CEO Dario Amodei, who on Saturday called on firms to slow down the development of AI and was backed by OpenAI boss Sam Altman and Elon Musk.

"The Trump Administration has stopped AI 'people' from doing bad, or potentially bad, 'things,' like Dario (Anthropic!), who is now pretending to be a 'perfect little angel'," the US president wrote.

Trump was asked repeatedly about the threat from AI during a weekend trip to Ireland but rejected calls for regulation.

Speaking to reporters on Air Force One on Sunday, Trump said he had heard directly from tech insiders the previous week on the issue.

Asked if he was downplaying their concerns he said: "No we are not downplaying but you know it's going to be more good than bad by a lot."
