TOP OF THE AGENDA

Questions mount over AI 'slowdown'

AI experts have been sounding the alarm bells, with bosses of major US-based firms, including Anthropic's Dario Amodei and OpenAI's Sam Altman, calling for the pace of development to slow down. An ex-Anthropic researcher then told us that staff building AI believed it could destroy humanity. President Donald Trump, however, has downplayed the warnings. "They're bringing up things that won't happen," he said, adding: "We're leading China on AI... I want to keep it that way because whoever wins AI, wins." Our tech and AI editor Zoe Kleinman, who has been following these warnings for years, says a slowdown might sound like a quick fix, but it's not an easy solution. How exactly would it be enforced - and who would police it?

• 'Genuinely frightened': A researcher who quit Anthropic has said he believes, at the current pace of development, "we could all die in the immediate future".

• Bioweapons threat: Anthropic said it has identified and disrupted attempts to use its AI model for "malicious activity".

• Wider reaction: Our correspondent Lily Jamali reports on how some Silicon Valley bosses have responded.

Before entering politics, Canada PM Mark Carney spent years in the top tiers of global finance, including as Bank of England governor. Now, he is looking to leverage his personal relationships with the world's wealthiest asset managers and business leaders to present Canada as an attractive investment destination as the bitter trade war with the US rages on. But there is no guarantee that the deep-pocketed investors will be easily sold.
