Nobel laureates also sign letter saying ASI technology should be barred until there is consensus that it can be developed ‘safely’

The Duke and Duchess of Sussex have joined artificial intelligence pioneers and Nobel laureates in calling for a ban on developing superintelligent AI systems.

Harry and Meghan are among the signatories of a statement calling for “a prohibition on the development of superintelligence”. Artificial superintelligence (ASI) is the term for AI systems, yet to be developed, that exceed human levels of intelligence at all cognitive tasks.

The statement calls for the ban to stay in place until there is “broad scientific consensus” on developing ASI “safely and controllably” and once there is “strong public buy-in”.

It has also been signed by the AI pioneer and Nobel laureate Geoffrey Hinton, along with his fellow “godfather” of modern AI, Yoshua Bengio; the Apple co-founder Steve Wozniak; the UK entrepreneur Richard Branson; Susan Rice, a former US national security adviser under Barack Obama; the former Irish president Mary Robinson, and the British author and broadcaster Stephen Fry. Other Nobel laureates who signed include Beatrice Fihn, Frank Wilczek, John C Mather, and Daron Acemoğlu.
