Many claims, including the key one that "Blockchain technology has the potential to revolutionize applications and redefine the digital economy," were neither discussed nor backed up with evidence. From a scientific point of view, this is insufficient. Worse, like many blockchain proponents, Underwood failed, in my opinion, to raise the right questions. Instead of focusing on "what block-chain could do," one should address "what blockchain can do better than other technologies." In this context, blockchain is often compared to existing solutions rather than to existing technologies, as in the proverbial comparison of apples and oranges. There may be any number of reasons, including operational, economic, or social, why an existing solution (as inadequate as it may be) has not been replaced in the marketplace.

Samsung's Galaxy S8 will come in two sizes, have an almost bezel-less, edge-to-edge "infinity" display and an iris scanner, the Guardian has learned. The Galaxy S8 will be announced in late March and go on sale on or around 21 April, later than the originally planned launch at Mobile World Congress in Barcelona in February due to knock-on effects of the Note 7 fiasco. The two variants will have screens in the 5in to 6in region, with the devices having the same or smaller proportions of previous versions of Samsung's flagship smartphone but with larger displays, according to several well placed sources talking to the Guardian. The S7 was available with either a 5.1in and 5.5in screen. The two smartphones are codenamed Dream and Dream 2, representing the smaller and larger Galaxy S8 respectively, according to two sources.

Horror movies have always reflected and explored the political climate of the eras that produced them. In the 1950s, Cold War paranoia led to a spate of films such as Invasion of the Body Snatchers about aliens hiding among us, looking to destroy humanity from within. Later the chaos and bloodshed of the Vietnam war inspired a cycle of cynical, anarchic and bloody movies such as Tobe Hooper's Texas Chainsaw Massacre and Wes Craven's Last House On the Left, in which the rules of civilised society collapse amid senseless, numbing violence. Horror cinema, with its in-built tropes of shock and tension, has always provided a convenient way for culture to process real-life fears. This is why Resident Evil 7, released this week to much critical acclaim, is an interesting benchmark for where horror video games are right now, and what they say about the world around us.

Number of years for the economy to double in size (a full circle represents 100 years) AI establishes a new relationship between people and machines, creating new factors of productivity and growth AI SOLVES KEY BUSINESS CHALLENGES AI CAN DOUBLE ECONOMIES' SIZE What is AI? AI involves multiple technologies that can be combined in different ways to sense, comprehend, act and learn. Slow growth Since the 1980s, GDP growth has slowed in many large economies. Weak productivity Total factor productivity has weakened in the past 10 years. Falling capital efficiency The marginal capital efficiency rate has dropped over 50 years. Labor and capital augmentation Makes more efficient use of the workforce and capital assets Innovation diffusion Uses AI to stimulate new ideas Aging workforce As populations age and birth rates slow, fewer people are available.

Artificial Intelligence, it seems, will deliver on its promise on many vectors. Low-skilled tasks that can be automated WILL be automated. This will start showing impact relatively soon. Some analysts like HfS research have projected a job loss of 640,000 by 2021. Moreover, automated code generators stand to replace human programmers at mass scale as well.

Phones that haven't yet been updated to the new version of iOS could fall victim to a range of security flaws. Bugs in the code of iOS can allow hackers to break into many of the most central parts of the iPhone or iPad. The problem could let people get access to things like unlocking and the OS's kernel, letting anyone who had access run apps and so potentially steal information. The problem is fixed by updating to the latest version of iOS, version 10.2.1. The update doesn't bring with it any major features, but fixes those problems, which could affect any devices after the iPhone 5 and the fourth generation of the iPad.

The following script is from "Artificial Intelligence," which aired on Oct. 9, 2016. Charlie Rose is the correspondent. The search to improve and eventually perfect artificial intelligence is driving the research labs of some of the most advanced and best-known American corporations. They are investing billions of dollars and many of their best scientific minds in pursuit of that goal. All that money and manpower has begun to pay off. In the past few years, artificial intelligence -- or A.I. -- has taken a big leap -- making important strides in areas like medicine and military technology. What was once in the realm of science fiction has become day-to-day reality. You'll find A.I. routinely in your smart phone, in your car, in your household appliances and it is on the verge of changing everything. On 60 Minutes Overtime, Charlie Rose explores the labs at Carnegie Mellon on the cutting edge of A.I. See robots learning to go where humans can'... It was, for decades, primitive technology.

Researchers are warning Android users off protecting their smartphones with a lock pattern, having found that the majority of them can be cracked within five attempts. The security measure lets a user unlock their handset by tracing a particular pattern across a grid of dots with their finger, and is available as an alternative to a PIN or password. Users are allowed five attempts to get the pattern right before the device detects something suspicious and locks itself. However, researchers from Lancaster University, the University of Bath and Northwest University in China claim to have cracked 95% of 120 unique lock patterns in less than five attempts, using video recordings and computer vision algorithm software.

A longstanding network of bogus "think tanks" raise disinformation to a pseudoscience, and their studies' pull quotes and flashy stats become the "evidence" driving viral, fact-free stories. Not to mention President Trump's tweets. These organizations have always existed: they're old-school propagandists with new-school, tech-savvy reach. They've been ginning up so-called research for everyone from shady corporations to anti-LGBTQ groups to white supremacists for decades--they're practiced, and their faux-academic veneer is thick and glossy. Which makes them harder to brush off than your garden-variety liar.
