Technology will replace the best teachers of the future with intelligent machines, according to the head of one of the UK's most famous public schools. Sir Anthony Shelden, the master of Wellington college, predicts that the change will happen within the next 10 years and will completely transform the education system. Teachers will remain in classrooms to set up equipment and maintain discipline according to Sir Anthony, but they will simply be assistants while the real education is done by artificial intelligence.

The new Apple TV 4K adds support for 4K video (naturally) as well as HDR, or High Dynamic Range, making for a significant upgrade to a product Apple once called a "hobby." The 4K resolution offers four times the pixels of the current 1080p HD model, while HDR provides a greater range of richer colors with supported titles and TV sets. Orders begin Sept. 15, and it ships starting Sept. 22. Customers who've purchased HD movies will receive upgrades in their iTunes libraries to corresponding 4K versions at no additional cost, and new titles in 4K will be sold at the same price as HD versions. Apple said that it's working with Netflix and Amazon Prime Video to bring their 4K libraries to Apple TV.

Its venerable phone line wasn't the only newly minted product Apple showed off at the iPhone 8 event on Tuesday. Eddie Cue announced onstage that the company will expand availability of its TV app to seven new countries by the end of the year and will be adding local news and sports programming as well. The TV app will be available in Australia and Canada next month, the spread to Germany, France, Sweden, Norway and the UK by the end of the year. US sports fans (that is, those that live in the country), will be able to track their favorite teams and have Apple TV push an on-screen notification whenever a game starts. By the end of the year, Apple also announced that users will be able to ask Siri directly to switch to a game.

You'd be hard pressed to find IT news these days that doesn't mention artificial intelligence (AI). Stephen Hawking, Bill Gates and Elon Musk continue to warn people of what a world with perfected AI might look like, while sci-fi films like The Terminator and The Matrix bring these fears to the big screen. But still AI research pushes on. Debates about AI capabilities often boil down to whether or not Artificial General Intelligence (AGI) can be achieved. The definition of AGI is heavily debated, but primarily refers to a machine with the same intellectual capabilities as a human.

A Chicago startup has raised $2.5 million in hopes of using artificial intelligence and Big Data to help insurance companies make smarter underwriting decisions more quickly. DataCubes raised the money from Seyen Capital and MK Capital. The company was founded last year by Kuldeep Malik, a co-founder of mobile-advertising software company Persio (formerly called Iris Mobile), and Harish Neelamana, who previously worked for insurers Zurich and Allstate. "I wanted to create a Big Data solution to solve a tangible business problem; my friend Harish is an expert in commercial insurance," Malik says. They're trying to disrupt the commercial insurance business by using artificial intelligence and machine learning.

A 52 million-year-old ankle fossil dug up in France shows the first primates were high flying acrobats in a find that could rewrite human history. The shape and size of the tiny bone suggests our earliest ancestors flexed and sharply extended their ankles to launch themselves into the air. For years, scientists believed the ancestors of today's humans, monkeys and apes were relatively slow and deliberate. But the new study found the first primates, which were about the size of a chipmunk, instead leapt through the trees. A 52 million-year-old ankle fossil (pictured) shows the first primates were high flying acrobats in a find that could rewrite human history.

These days, it's tough to avoid newspaper headlines warning that artificial intelligence is coming for your job. The problem is that, often, the only thing these oversimplifications get right is that there is in fact an important connection between automation and work. What's surprising is how many examples there are of AI acting as the catalyst for new hiring, higher wages, and happier employees. The reality is that the impact of AI on the workforce is complex, nuanced, and still very much in transition. A Deloitte study of automation in the U.K. found that 800,000 low-skilled jobs were eliminated as the result of AI and other automation technologies.

Although many companies today possess massive amounts of data, the vast majority of that data is often unstructured and unlabeled. In fact, the amount of data that is appropriately labeled for a specific business need is typically quite small (possibly even zero), and acquiring new labels is usually a slow, expensive endeavor. As a result, algorithms that can extract features from unlabeled data to improve the performance of data-limited tasks are quite valuable. Most machine learning practitioners are first exposed to feature extraction techniques through unsupervised learning. In unsupervised learning, an algorithm attempts to discover the latent features that describe a data set's "structure" under certain (either explicit or implicit) assumptions.

A man who spent £3,500 creating a hyper-realistic sex robot that joins him and his wife in bed has said she is part of the family - so much so that'Samantha' even joins the couple and their children on the sofa. Arran Squire, 36, from North Wales, brought his robot along for it's debut on ITV's This Morning on Tuesday, and her presence both amused and horrified presenters Phillip Schofield and Holly Willoughby. Phillip warned viewers to switch off if there were young children watching, before playing a recording of some of the ardent responses the robot is designed to make on cue. Joking it would be like'making love to a car GPS', Phil went on to say he had touched the doll and it was so cold'it felt like a corpse'. Holly was shocked to learn that Arran allowed his children to see the doll, having assumed he would keep Samantha hidden.
