YouTube Description

as posted by the channel

The UK's top cybersecurity official has told Sky News that AI models such as Mythos are "warning shots" for the UK about the danger of powerful AI.

Richard Horne, the head of the National Cybersecurity Centre, stressed the need for organisations to improve their cyber defences, saying they needed to act with "10 times urgency".

But he said he did not consider AI a national security threat at present, as new models were "not finding new attacks, they're just exposing more security vulnerabilities".
