Why doesn't the United States have high-speed bullet trains like Europe and Asia? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world. First, let me state that I am a huge fan of high-speed rail. My first experience with high-speed rail was on Taiwan's high-speed rail line in 2008 which shortened the time it took to traverse the island from five hours to two. My second was on my honeymoon when my wife and I traversed continental Europe on its clean and efficient high-speed rail network. It kills me to think that for the amount of money and resources we have spent on the second Iraq war, we could have built the backbone of a nationwide high-speed rail network and subsidized its use for a number of years while it ramped up to optimal capacity.

Philip Hammond says he wants the UK to become a "world leader" in 5G, the next-generation mobile technology that proponents say is the key to an internet-connected world of driverless cars, smart home appliances, delivery drones and lightning-fast video on the go. The government, which has published a 70-page tome on its future 5G strategy, said in the budget it would invest up to £16m to run trials and support the technology's development, to make sure the UK is at the crest of the "next wave of mobile technology services". However, 5G, which is set to be rolled out in the UK next decade, also has its critics. They argue consumers don't need the superfast speeds the upgrade from current 4G technology promises, and many in the industry believe that logistical issues mean that 5G may not be properly rolled out in the UK for decades. In the meantime, there are still basic infrastructure issues – including rural areas with little or no broadband coverage at all – that need sorting out.

March 11, 2017 --Dominating the night sky, Earth's natural satellite is often the first target to catch the eye of budding astronomers, and now the moon's siren call is pulling the world's leading space powers too. The five space agencies responsible for building the International Space Station (ISS) met last month in Tsukuba, home to the Japanese space agency JAXA, to decide what comes after the aging ISS. Discussions advanced an evolving plan to build a lunar space station, settling on a tentative orbit and paving the way for finalized plans that may come in late 2017 or early 2018. But friction remains around the ultimate goal of the station: Will the ISS successor be a truly lunar space station or a spaceport on the way to Mars? With the ISS's decommissioning tentatively scheduled for 2024, the International Spacecraft Working Group (ISWG), composed of the American, Russian, Japanese, European, and Canadian space agencies, is looking ahead to the next phase of human space exploration.

On this day in 1818, the novel "Frankenstein; or, The Modern Prometheus", by 21-year-old author Mary Wollstonecraft Shelley, was published. Frankenstein is often considered the world's first science fiction novel, as it mixes elements of Victorian ghost stories with elements of modern technology, chemistry and biology. She describes the weather at the time as a "wet, unpleasant summer, continuous rainfall kept us inside the house." Bored, the friends worked on creepy stories, reflecting the gloomy atmosphere surrounding them, but only Shelley completed hers. The year 1816 is today famous as the year without a summer.

Unless you've been hiding out in a doomsday bunker you'll have heard the news that the robots are coming for your job. They are already delivering takeaways in Washington, DC, flipping burgers in California, doing data entry in accounting firms worldwide, writing articles for the Associated Press, appealing parking tickets, correcting errors on Wikipedia, managing Amazon's warehouses, creating ads for Coca-Cola and helping in complex surgery. Soon "there will be fewer and fewer jobs that a robot cannot do better", according to the gloomy prediction of Elon Musk, the Tesla and SpaceX chief executive and notorious worrier about the robot apocalypse. Lest you think your role is safe, a recent report by the McKinsey Global Institute brings the cheery news that by 2055 robots will be doing more than half of what qualifies as work in today's world. McKinsey has provided a search tool where you can check how vulnerable your occupation is to partial or complete automation, but I'll save you the trouble: unless your job involves owning the corporation that builds the robots it's probably deemed at risk.

As Carrington Institute's most promising new Agent, Joanna Dark must uncover the truth behind the dataDyne Corporation's recent technological breakthroughs - breakthroughs which could have serious consequences for mankind."

Gone are the days of milk maids on stools. At the 56,000-square-metre Arla factory in Taulov, Denmark, cheese production is moving towards complete automation - even when it comes to milking the cows. "The biggest challenge is to keep the variation small within the process," explains senior director Jørgen Greve. "About 70 per cent is automated." Once a robot arm has milked the cows, Arla analyses samples for protein and fat content.

March 9, 2017 --Physicist Stephen Hawking may be a proponent of artificial intelligence, but he has also been outspoken about the potential challenges it creates. In a recent interview, he sounded a similar tone, and offered a solution that conservatives may find hard to accept. Speaking to The Times of London to commemorate being awarded the Honorary Freedom of the City of London, a title that was conferred on him on Monday, Professor Hawking expressed optimism for the future. He added, however, that he is concerned about artificial intelligence (AI), as well as other global threats. "We need to be quicker to identify such threats and act before they get out of control," Hawking said.

For Silicon Valley, the headline was sweet nectar: Google DeepMind, the world's hottest artificial intelligence lab, embraces the blockchain, the endlessly fascinating idea at the heart of the bitcoin digital currency. The lab's re-imagining of the blockchain has very little to do with AI--or the blockchain, for that matter. If you want AI crossed with the blockchain, try wrapping your head around Numerai, the world's strangest hedge fund. To DeepMind's credit, its new project depends less on trendy ideas than an apparent desire to solve a real problem in the real world--one that involves the most private and personal information. DeepMind is building an auditing system for healthcare data. That may not sound sexy, but it matters.

This has been a dark week in the world of technology, with WikiLeaks' mammoth'Vault 7' document release making for some deeply unpleasant reading. The 8,761 files published by the whistle-blowing organisation allegedly came straight from the CIA, which is believed to have been using a variety of hacking methods to secretly spy on people through their electronic devices. The agency is also said to be capable of pinning the blame for cyber attacks on other countries. WikiLeaks is set to follow this up by publishing the redacted details of all of the CIA's cyber weapons, but will give technology companies initial exclusive access to them, to prepare themselves against hackers. Fortunately, there are also a number of simple steps that ordinary people can take to protect themselves, without going off-grid.
