Dario Amodei, the chief executive of Anthropic, has joined calls for a slowdown in AI development. A former Anthropic researcher told the BBC that AI staff feel real fear over the fate of humanity. OpenAI's boss and Elon Musk join in backing slowing down what they call reckless AI development. US President Trump has a different stance. He says whoever wins AI wins, and downplays risks as things that are unlikely.

The warnings are coming from experts and company chiefs. They urge greater caution before pushing ahead. Trump's view stands in stark opposition to that outlook. He argues the race for AI superiority outweighs potential dangers.
