Donald Trump has dismissed growing concerns about the safety of artificial intelligence as a "hoax", rejecting calls from industry figures for stronger safeguards on the technology. His comments came after Jack Clark, co-founder of Anthropic, told the BBC that a mandatory, independently verifiable "kill switch" may be needed across the AI industry, part of a wider wave of warnings from tech executives and staff that recently triggered a sell-off in technology shares.

Trump compared the safety warnings to the "Global Warming Scam" and past "Russia hoax" claims, insisting the only guardrail AI needs is a "strong and smart" president, and accused critics of aiding China in the AI race. Other voices are pushing back: Microsoft AI has published new "humanist AI" guidance, UK Business Secretary Jonathan Reynolds urged caution without "hyperbole", and Senator Bernie Sanders and Steve Bannon are both due to speak at a Washington event calling for a rethink of AI policy, with Sanders warning of an "existential threat" to humanity.
