Nouriel Roubini calls cryptocurrency the ‘mother of all bubbles’ as it falls below $8,000The economist credited with predicting the 2008 global financial crisis said a 12% fall in the value of bitcoin on Friday was the latest proof that the cryptocurrency was the biggest bubble in history and destined for a crash.Nouriel Roubini, professor of economics at New York University, said bitcoin was “the mother of all bubbles” favoured by “charlatans and swindlers” as it fell below $8,000 (£5,600) early on Friday, marking a 30% drop since the beginning of the week as investors became increasingly twitchy about a clampdown on cryptocurrencies by regulators.

After spending most of her life bouncing off video games, Jessica Furseth finally discovers the joy and practical benefits of play‘Luke, how do I get this power moon? Luke!” I’m playing Super Mario Odyssey while my partner, Luke, is trying to work. “You’ll figure it out,” he says patiently. Luke has been playing video games since he was a child, but this is my first ever game, and he’s thrilled that I’m invested in Mario’s quest to save Princess Peach.Considering it’s a $100bn (£70bn) industry, gaming is a surprisingly “love it, or just don’t get it” kind of activity. I’ve tried video games a few times over the years, as people seemed to be having so much fun with them. But I never got into it. I kept dying, so I gave up. Last year, though, my curiosity was piqued again as I watched Luke play the newest Mario game with his children. One slow Sunday, I picked up the Nintendo Switch. No one was more surprised than me when I kept coming back to the game, and eventually beat Bowser. Continue reading...

Having more screen space makes people more productive, but it’s not necessarily best distributed over multiple monitorsWill I be able to do more work with three monitors? JeanResearch shows that people can get more work done if they have more screen area available, and using multiple monitors is a simple way to double or triple your workspace. However, that doesn’t mean having three screens is the best option for you or anyone else. The final decision depends on the way you work, the programs you run, the amount of desk space you have available, and how much you are willing to spend.

Data has become the world’s most important resource. Now Silicon Valley giants want to keep government from standing in the way of profitsOne hundred and sixty years ago, the first transatlantic telegram traveled from Britain to the United States along a rickety undersea wire. It consisted of twenty-one words – and took seventeen hours to arrive.Today, the same trip takes as little as 60 milliseconds. A dense mesh of fiber-optic cables girdles the world, pumping vast quantities of information across the planet. The McKinsey Global Institute estimates that 543 terabits of data are flowing across borders every second. That’s the equivalent of roughly 13 million copies of the complete works of Shakespeare.

Around the world, a handful of visionaries are plotting an alternative ​online ​future​.​ ​Is it really possible to remake the internet in a way that’s egalitarian, decentralised and free of snooping​?​The office planner on the wall features two reminders: “Technosocialism” and “Indienet institute”. A huge husky named Oskar lies near the door, while the two people who live and work here – a plain apartment block on the west side of Malmö, Sweden – go about their daily business.Aral Balkan and Laura Kalbag moved here from Brighton in 2015. Balkan has Turkish and French citizenship, and says their decision was sparked by two things: increasing concerns about the possibility of Britain leaving the EU, and the Conservative government’s Investigatory Powers Act, otherwise known as the snoopers’ charter, some of which was declared unlawful this week by the court of appeal. The legislation cut straight to the heart of what now defines the couple’s public lives: the mesh of corporate and government surveillance surrounding the internet, and how to do something about it.

With more than half of young adults admitting to excessive use of smartphones, we look at the apps designed to break the habitAs a tech writer who has written regularly about apps, I’m well aware of the addictive nature of smartphones. It was during a 2am panic attack after waking up, reaching for my smartphone and reading a tweetstorm about the latest Donald Trump controversy that I realised I may have a problem. That, and the fact that even my 10-year-old son had started telling me to put my phone down when he caught me not paying attention.I’m not alone. When Deloitte surveyed 4,150 British adults in 2017 about their mobile habits, 38% said they thought they were using their smartphone too much. Among 16- to 24-year-olds, that rose to more than half. Habits such as checking apps in the hour before we go to sleep (79% of us do this, according to the study) or within 15 minutes of waking up (55%) may be taking their toll on our mental health.

Some say the firm is already overvalued at $60bn. But its founder’s vision is now truly ambitiousRacy valuations for loss-making businesses are nothing new to hard-nosed Wall Street types.

Plenty also lost their shirts with punts on the “next big thing”.Elon Musk knows more than most about this tricky game of risk and reward. The entrepreneur founded and sold software company Zip2 for $305m to Compaq; he also established online payment giant PayPal, which was sold to eBay for $1.5bn. Continue reading...
