Engineers are testing a new robot rescue system in the Greek islands, hoping it will be able to save some refugees while trying to cross from Turkey to Greece.

From self-driving vehicles and semi-autonomous robots to intelligent algorithms and predictive analytic tools, machines are increasingly capable of performing a wide range of jobs that have long been human domains. A 2013 study by researchers at Oxford University posited that as many as 47% of all jobs in the United States are at risk of "computerization." And many respondents in a recent Pew Research Center canvassing of technology experts predicted that advances in robotics and computing applications will result in a net displacement of jobs over the coming decades – with potentially profound implications for both workers and society as a whole. The ultimate extent to which robots and algorithms intrude on the human workforce will depend on a host of factors, but many Americans expect that this shift will become reality over the next half-century. In a national survey by Pew Research Center conducted June 10-July 12, 2015, among 2,001 adults, fully 65% of Americans expect that within 50 years robots and computers will "definitely" or "probably" do much of the work currently done by humans.

New drone footage has captured the growing pile of lifejackets abandoned by migrants after reaching the Greek island of Lesbos. It is now more than three metres deep in some places, with boats being added to the pile.

Minecraft is to become a testing ground for artificial intelligence experiments. Microsoft, owner of the popular video game, revealed that computer scientists and amateurs will be able to evaluate and develop AI software using its virtual landscapes from July. The company says Minecraft is more "sophisticated" than existing AI research simulations and cheaper to use than building a robot. "This is the state-of-the-art," said Prof Jose Hernandez-Orallo from the Technical University of Valencia, one of a small group of academics given early access to the software. "At this moment there is nothing comparable, and this is just in its beginnings, so I see many possibilities for it."

Fighting cyber attacks with artificial intelligence The next frontier of anti-virus software is leveraging artificial intelligence (AI) to not only predict what threats are out there, but to also actively fight back before they strike. This is according to American-based Cylance's chief marketing officer, Greg Fitzgerald, speaking at the NetEvents Press and Analyst Summit in Rome, Italy.The company says it is "revolutionising cyber security through the use of AI and machine learning to proactively prevent advanced persistent threats and malware". Cylance today announced it is expanding into the Europe, the Middle East and Africa (EMEA) with the establishment of a London-based team led by Evan Davidson, former enterprise sales director at FireEye. It also established a channel partnership with CoreSec Systems, which supplies cyber security and networking solutions in Sweden and Denmark.

The term Artificial Intelligence was originally coined by John McCarthy in 1955, defining it as "the science and engineering of making intelligent machines". Now more than a half a century old, the field of AI and machine learning is finally achieving some of its oldest goals by being used successfully in areas such as data mining, industrial robotics, logistics, speech recognition, banking software, medical diagnosis and search engines. Tech giants have all been investing heavily in AI and Machine Learning. In 2010 Facebook introduced facial recognition technology, and in 2013 Mark Zuckerberg dedicated a lab to AI research. In 2014 Google bought artificial intelligence startup DeepMind for 400 million ( 263 million), making it one of the largest tech acquisitions to date.

In 2012, IBM Watson went to medical school. So said The New York Times, announcing that the tech giant's artificially intelligent question-and-answer machine had begun a "stint as a medical student" at the Cleveland Clinic Lerner College of Medicine. This was just a metaphor. Clinicians were helping IBM train Watson for use in medical research. But as metaphors go, it wasn't a very good one.

It was hailed as the most significant test of machine intelligence since Deep Blue defeated Garry Kasparov in chess nearly 20 years ago. Google's AlphaGo has won two of the first three games against grandmaster Lee Sedol in a Go tournament, showing the dramatic extent to which AI has improved over the years. That fateful day when machines finally become smarter than humans has never appeared closer--yet we seem no closer in grasping the implications of this epochal event. Late last year, SpaceX co-founder Elon Musk warned that AI could take over the world, sparking a flurry of commentary both in condemnation and support. For such a monumental future event, there's a startling amount of disagreement about whether or not it'll even happen, or what form it will take.

Social networking giant Facebook is using its artificial intelligence (AI) technology and resources to map the entire Earth and launch the world's most detailed population maps that will help it beam cheap internet to remote areas. To begin with, the Facebook AI team crunched 14.6 billion images of maps from across 20 countries, including India, covering 21.6 million sq kms to come up with the first detailed map of human settlement for these countries. "This is an impressive project from our team developing solar-powered planes for beaming down internet connectivity and our AI research team. Many people live in remote communities and accurate data on where people live doesn't always exist," wrote Facebook CEO Mark Zuckerberg in a latest post. The 20 countries mapped were Algeria, Burkina Faso, Cameroon, Egypt, Ethiopia, Ghana, India, Ivory Coast, Kenya, Madagascar, Mexico, Mozambique, Nigeria, South Africa, Sri Lanka, Tanzania, Turkey, Uganda, Ukraine and Uzbekistan.

Each are British artificial intelligence and machine learning startups bought by US tech giants--HP, Google, Microsoft, and Apple, respectively. Alongside growing VC funding in AI, US tech firms are snapping up British-founded startups, leading to concerns that the UK is losing the best of its artificial intelligence to Silicon Valley just as it becomes a key technology. Simon Walker, partner in corporate technology at law firm Taylor Wessing, said the sale of AI startups to US firms isn't new and doesn't look like it'll stop soon. "It is obviously disappointing that the AI cannot be retained in the UK," he said. "However, top-of-the-market AI, such as that developed by companies such as SwiftKey and DeepMind, requires huge investment and a significant platform for its use and it is only very large tech companies which have the necessary resources and platforms."
