Dario Amodei, the chief executive of Anthropic, is backing efforts for a slowdown in AI development. A former Anthropic researcher told the BBC that AI staff are genuinely frightened over the fate of humanity. OpenAI's boss and Elon Musk are supporting putting brakes on what they call reckless AI development. US President Trump takes a different line. He says whoever wins AI wins, and dismisses threats as things that won't happen.

The warnings are issued by industry leaders and researchers. They want more caution before further advances. Trump's view stands in stark opposition to these warnings. He argues the race for AI superiority is more important than any downsides.
