42 leading mathematicians warn that AI existential risk is real and urgent

42 Fellows of the Royal Society, including Fields Medal winners Martin Hairer and Peter Scholze, signed an open letter warning that AI existential risk is real and urgent. The mathematicians noted that leading models have solved open research problems within months and that such capabilities could be equally effective in cyberweapons or bioweapons, cautioning that by the time the public grasps the situation it may be too late to act.
