Over 1,000 high-profile artificial intelligence experts and leading researchers have signed an open letter warning of a "military artificial intelligence arms race" and calling for a ban on "offensive autonomous weapons". The letter, presented at the International Joint Conference on Artificial Intelligence in Buenos Aires, Argentina, was signed by Tesla's Elon Musk, Apple co-founder Steve Wozniak, Google DeepMind chief executive Demis Hassabis and professor Stephen Hawking along with 1,000 AI and robotics researchers.
The letter states: "AI technology has reached a point where the deployment of [autonomous weapons] is – practically if not legally – feasible within years, not decades, and the stakes are high: autonomous weapons have been described as the third revolution in warfare, after gunpowder and nuclear arms."
Solar Impulse, the aeroplane that is powered only by the sun, has landed in Hawaii after making a historic 7,200km flight across the Pacific from Japan. Pilot Andre Borschberg brought the vehicle gently down on to the runway of Kalaeloa Airport at 05:55 local time (15:55 GMT; 16:55 BST). The distance covered and the time spent in the air - 118 hours - are records for manned, solar-powered flight.
The duration is also an absolute record for a solo, un-refuelled journey. Mr Borschberg's time betters that of the American adventurer Steve Fossett who spent 76 hours aloft in a single-seater jet in 2006. Despite being in the cockpit for so long, the Swiss pilot said he did not feel that tired: "Interestingly, not really. "I am also astonished. We got so much support during the flight from so many people; it gave me so much energy."
You will only be allowed to express yourself if you become a hologram!
Late last year the Spanish government passed a law that set extreme fines for protesters convening outside of government buildings. In response to the controversial Citizen Safety Law, which will take effect on July 1, Spanish activists have staged the world's first ever virtual political demonstration. After months of massive flesh-and-blood protests against the so-called 'gag law', thousands of holograms last night marched in front of the Spanish parliament in Madrid.
Apple's goal has always been to make powerful technology more accessible, more relevant and ultimately, more personal. Apple Watch represents a new chapter in the relationship people have with technology. It's the most personal product Apple has ever made, because it's the first one designed to be worn.
High-quality watches have long been defined by their ability to keep unfailingly accurate time, and Apple Watch is no exception. In conjunction with your iPhone, it keeps time within 50 milliseconds of the definitive global time standard. It even lets you customize your watch face to present time in a more meaningful, personal context that's relevant to your life and schedule.
