Artificial intelligence is a growing field for tech companies, but among futurists and other tech industry figures, the potential unintended consequences of AI are an equally growing concern. Count Elon Musk among those worried about AI's possible effects. At the National Governors Association's 2017 meeting, Musk warned about the disruptive effects in robotics and other fields, cautioning that people "should be really concerned about AI." "Until people see robots going down the street killing people, they don't know how to react because it seems so ethereal," Musk said. "AI is a rare case where I think we need to be proactive in regulation instead of reactive. Because I think, by the time we are reactive in AI regulation, it's too late."

Spanish authorities say 33 people, including six children under 10 years old, have been injured in a roller coaster collision in Madrid. Emergency services say that 27 people needed hospital treatment for minor injuries when two roller coaster cars collided Sunday on the "Tren de la Mina" at Madrid's Parque de Atracciones theme park. Emergency services spokeswoman Carmen Camacho said that none of the injuries appeared to be serious. She said that the riders were treated for neck, back and stomach pains. Park representatives told Spanish news agency Europa Press that the roller coaster had passed a daily safety inspection Sunday morning.

Appearing before a meeting of the National Governor's Association on Saturday, Tesla CEO Elon Musk described artificial intelligence as "the greatest risk we face as a civilization" and called for swift and decisive government intervention to oversee the technology's development. "On the artificial intelligence front, I have access to the very most cutting edge AI, and I think people should be really concerned about it," an unusually subdued Musk said in a question and answer session with Nevada governor Brian Sandoval. Musk has long been vocal about the risks of AI. But his statements before the nation's governors were notable both for their dire severity, and his forceful call for government intervention. "AI's a rare case where we need to be proactive in regulation, instead of reactive. Because by the time we are reactive with AI regulation, it's too late," he remarked.

Patrick Tucker, Defense One: Russian Weapons Maker To Build AI-Directed Guns Kalashnikov's upcoming product shows how the US and Russia are on wildly different paths to autonomy. The maker of the famous AK-47 rifle is building "a range of products based on neural networks," including a "fully automated combat module" that can identify and shoot at its targets. That's what Kalashnikov spokeswoman Sofiya Ivanova told TASS, a Russian government information agency last week. It's the latest illustration of how the U.S. and Russia differ as they develop artificial intelligence and robotics for warfare. The Kalashnikov "combat module" will consist of a gun connected to a console that constantly crunches image data "to identify targets and make decisions," Ivanova told TASS. A Kalashnikov photo that ran with the TASS piece showed a turret-mounted weapon that appeared to fire rounds of 25mm or so.

U.S. Sen. Charles Schumer is asking Amtrak to discard the idea of creating new economy seating with reduced legroom aboard its trains. Schumer says in a statement Sunday that Amtrak should find other ways to save money without burdening passengers. Outgoing Amtrak co-chief executive Wick Moorman said last week that the company was looking at creating the "economy" seating that would add more rows of seats in an effort to make more money. Schumer is calling the idea "right out of the airline's playbook." The senator from New York is urging Amtrak to "scrap the shrinking seats idea" and look at other ways of making money.

Tennis - Wimbledon - London, Britain - July 16, 2017 Switzerland's Roger Federer celebrates winning the final against Croatia's Marin Cilic REUTERS/Toby Melville Reuters From 1877 to 1921 the men's singles was decided on a challenge-round system with the previous year's winner automatically qualifying for the final (British unless stated): Winner of all-comers' final declared champion. Not all U.S. presidents are missed once they leave the White House. The Tesla and SpaceX CEO urged governors to regulate artificial intelligence before it's too late. Administration officials traveled to Providence to gain support from key players like Gov. Brian Sandoval. Prime Minister Justin Trudeau and other foreign leaders reached out to U.S. governors ahead of slated talks.

The BBC says Jodie Whittaker is the next star of the long-running science fiction series "Doctor Who" -- the first woman to take the title role. Whittaker, who starred in detective drama "Broadchurch," will replace Scottish actor Peter Capaldi. Whittaker is the 13th incarnation of the Doctor, a galaxy-hopping Time Lord who travels in the Tardis, a time machine shaped like an old-fashioned British police telephone booth. The 54-year-old program has a firm place in Britain's cultural life, and the announcement was made during a live television broadcast Sunday after the Wimbledon men's tennis final. "Doctor Who" was first broadcast in 1963.

The age of the robot has been predicted for decades. First used as a term to mean automated labor back in the 1920s, and popularised in the classic 1927 slient movie Metropolis, they have been a regular feature of science fiction ever since. The fact that robots and science fiction go hand in hand – and that predictions that we will soon have robot helpers being regular features of future-gazing since the 1930s – has meant that the idea of robots becoming a central part of our lives have become so familiar that we've come to ignore them. Yet robots have been a reality in manufacturing for decades, having become cost-effective production-line solutions by the 1970s. The Roomba – an automated vacuum cleaner that is perhaps the most famous domestic-helper robot – was launched back in 2002, and has sold more than 10 million units worldwide.

But a widely publicized new memoir about America's covert drone war fails to mention the "outflow increases," as one internal Air Force memo calls it. One might ask Velicovich to explain the deaths of Warren Weinstein, an American citizen, and Giovanni Lo Porto, an Italian citizen -- both aid workers who were killed by an American drone strike that was targeting Al Qaeda members in Pakistan. In the acknowledgments section of the memoir, Velicovich mentions that the forthcoming movie will be directed and produced by Michael Bay, the filmmaker behind "Transformers," "Pearl Harbor" and "Armageddon." Alex Edney-Browne (@alexEdneybrowne) is a PhD candidate at the University of Melbourne, where she is researching the psycho-social effects of drone warfare on Afghan civilians and veterans of the U.S. Air Force's drone program.

NEWSEUM: The troops of tomorrow may be able to pull the trigger using only their minds. As artificially intelligent drones, hacking, jamming, and missiles accelerate the pace of combat, some of the military's leading scientists are studying how mere humans can keep up with the incredible speed of cyber warfare, missiles and other threats. One option: Bypass crude physical controls -- triggers, throttles, keyboards -- and plug the computer directly into the human brain. In one DARPA experiment, a quadriplegic first controlled an artificial limb and then flew a flight simulator. Future systems might monitor the users' nervous system and compensate for stress, fatigue, or injury.
