Researchers remain divided over both the probability and timescale of extreme AI risks.\n\nThe UK-backed International Scientific Report on the Safety of Advanced AI says experts disagree about the likelihood that humanity could lose control of future general-purpose AI systems.\n\nIt says such scenarios deserve consideration but stresses that the probability of extreme control failures remains highly contentious and research assessing those risks is limited.\n\n## Pressure Builds on Downing Street\n\nThe protest puts those disagreements directly outside the centre of British government as ministers face growing pressure to decide how aggressively advanced AI should be regulated.\n\nPrime Minister Andy Burnham acknowledged at Prime Minister's Questions on 9 September that [AI poses risks to national security](https://www.ibtimes.co.uk/barack-obama-urges-government-action-ai-development-1819731), while also arguing that the technology could provide solutions that make the country safer.\n\nThe government has pointed to the work of the AI Security Institute, which evaluates advanced models and studies emerging risks.\n\nCampaigners, however, argue that testing and voluntary safeguards are insufficient if companies continue developing increasingly capable systems before governments establish stronger controls.\n\nThat disagreement sits at the heart of the Downing Street protest. The demonstrators' 10% extinction warning is not a settled scientific forecast, but it captures the question they want ministers to confront: how much risk should society accept while the capabilities of advanced AI continue to accelerate?\n\nFor protesters, waiting until those risks are proven could itself be dangerously late.\n\n© Copyright IBTimes 2026.
