Amid the growing warnings for "AI doomsday", US President Donald Trump on Sunday slammed critics of artificial intelligence, terming them "negative forces".Donald Trump's remarks came after Anthropic CEO Dario Amodei, OpenAI's Sam Altman raised alarm over AI. (AP)"I think you have a lot of negative forces that are bringing it up that shouldn't be bringing it up, and they're bringing up things that won't happen," Trump told reporters during a visit to Ireland.The US President's remarks come in the aftermath of some AI executives and employees raising concerns about its fast progress, while calling for the “pacing” of the development of models. Among them are Anthropic chief executive officer Dario Amodei, OpenAI CEO Sam Altman, and Eon Musk.What have AI leaders said?Amodei, in a post on his personal website, cited risks in “superintelligent” computer systems, including loss of control and its misuse of cyberattacks and bioterrorism as well as economic disruption.The Anthropic CEO's post came amid a host of resignations in artificial intelligence firms. A former Anthropic researcher, who resigned recently, warned that the company and its rival OpenAI were racing to build technologies that “could kill us all by the end of the decade.”In response, Amodei told CNN that he “agrees more than he disagrees” with him, but said Anthropic was a “more responsible player.” “He wasn't calling out to us. He was calling out the dynamic of the industry as a whole, moving too fast,” Amodei said.However, in his blog post, Amodei said building AI too fast “is reckless.” “We must slow the pace at which we improve the capabilities of AI models. Progress will still seem fast, and we must make wise use of the time we gain,” he said. Altman agreed with Amodei on the “need to pace the frontier”, saying it was a primary topic of discussion at OpenAI in recent weeks. Musk, in a brief response, said, “Dario is right.”
