Dario Amodei, the leader of Anthropic, supports demands for a slowdown in AI development. A former Anthropic researcher told the BBC that AI staff are deeply worried about what lies ahead. OpenAI's boss and Elon Musk join in backing slowing down what they call reckless AI development. US President Trump takes a different line. He says whoever wins AI wins, and brushes off dangers as things that are unlikely.

The warnings are issued by experts and company chiefs. They are calling for care before pushing ahead. Trump's view is very different from those concerns. He argues the race for AI superiority outweighs any downsides.
