By now, everyone's seen the videos of Boston Dynamics robot dog, Spot. It can walk, run, hop on two legs and even dance -- it's mighty impressive. But with every video released by the American robotics firm, it felt like we were edging closer to the ultimate goal of four-legged drones that could be equipped for battle and replace soldiers. However, Boston Dynamics has come together with a coalition of other robotics experts to plead with companies across the sector to please never give the robots guns. The letter, which was first reported by Axios, has been signed by Boston Dynamics, Agility Robotics, ANYbotics, Unitree, Clearpath and Open Robotics.

Have you ever heard of a lachetous vine? Maybe you just finished up some worryless tasks? Those words sound vaguely familiar -- perhaps you think you've heard them before but aren't sure you could explicitly define them. That's because they're gibberish -- part of an endless stream of words conjured up by an algorithm programmed to make new words that sound as believable as possible. The made-up words are generated by the website thisworddoesnotexist.com, which is a creation of former Instagram engineer Thomas Dimson, The Verge reports.

File photo - A Google carpet is seen at the entrance of the new headquarters of Google France before its official inauguration in Paris, France Dec. 6, 2011. A recently surfaced Google video discusses a creepy concept for collecting vast quantities of user data that could span generations. The video, which was obtained by The Verge, paints an unsettling picture of how data could theoretically be harnessed on an epic scale. The Verge reports that the video was produced in 2016 by X, a research and development subsidiary of Google's parent company Alphabet. X, formerly known as Google X, describes itself as a "moonshot factory" focused on developing technologies to make the world "a radically better place."

China has built the world's fastest supercomputer, capable of making 93 quadrillion calculations a second. And for the first time, it's entirely powered by Chinese-made processors, following a US ban on exporting chips for devices suspected to be used for nuclear research. The Sunway TaihuLight supercomputer, which is located at the state-funded Chinese Supercomputing Center in Wuxi, a city near Shanghai in eastern China, is more than twice as powerful as previous record-holder Tianhe-2, according to TOP500, a research organization that ranks the powerful computers twice a year. The milestone comes a year after the United States barred exports of computer chips to China for use in its supercomputers, citing concerns that the machines had been used in "nuclear explosive activities." In turn, by ramping up development of its own chips, China has come to surpass the US' own achievements in supercomputing: the top-placing American creation, the Department of Energy's Titan, secured third place ranking on TOP500's list, below China's two-record breaking supercomputers. "It's not based on an existing architecture.
