Back in January, the Doomsday Clock was reset to 89 seconds to midnight, the nearest it has ever got to its figurative “end times” since its conception in 1947. Set up by the Bulletin of the Atomic Scientists, the Clock originally offered a visual representation of the threat that nuclear warfare posed to humanity. In 2007, its remit was expanded to include climate change, with artificial intelligence, biological weapons and nanotechnology also now considered.
