Changing world: "As the first generation of self-driving cars and battlefield warbots filter into society, scientists are working to develop robots with moral decision-making skills." THE World Science Festival held in Brisbane in early March confirmed that robots, artificial intelligence and machine learning were now part of our lives. Thousands attending the festival came to watch, touch and play with cute, shiny robots capable of dodging objects, following commands and engaging in smart banter. However, if the future has arrived, now we have to deal with it. The World Science Festival was also an important forum as world experts discussed robot morality and ethics and what role we wanted robots to play in the future.

One of the tropes of science fiction is the uncanny valley -- the phenomenon of a robot looking eerily human-like but not quite right in some intangible way. Another is the breakdown in the distinction between human and machine. And a third is artificial intelligence becoming so complex and sophisticated that humans are no longer able to understand or control it. Well, not to be the bearer of bad news, but all of those tropes from the movies are already happening. The good news is that some of these advances have the potential to make our lives a lot better.

Summary: At least one instance of Real Time Predictive Model development in a streaming data problem has been shown to be more accurate than its batch counterpart. Whether this can be generalized is still an open question. It does challenge the assumption that Time-to-Insight can never be real time. A few months back I was making my way through the latest literature on "real time analytics" and "in stream analytics" and my blood pressure was rising. The cause was the developer-driven hyperbole that claimed that the creation of brand new insights using advanced analytics has become "real time".

When Google's AlphaGo program beat grandmaster Lee Se-Dol four games to one, both programmers and professional Go players were surprised. The general consensus was that it would be years before a computer could defeat a human at the complex board game, which players describe as requiring elegance and imagination. Director of the MARCS Institute for Brain, Behaviour and Development and electrical engineering professor, Jon Tapson, said AlphaGo's victory was cause for a re-evaluation of how we use artificial intelligence (AI). "They could find ways of manipulating the stock market -- maybe by buying and selling shares in rapid succession to create the illusion of a change in market sentiment," he said. He said unless there was reason to go looking, it was unlikely humans would notice that kind of behaviour, and that it would be difficult to program or regulate the actions of an AI if we do not know how it makes decisions.

Throughout that history, technology has brought comfort, ease, and prosperity. And all along it has taken jobs, disrupted lives, and changed the way people live and think. Each new age of innovation has brought a revolution. First, there was steam, then mass production, and late last century information technology. Now, researchers and thought leaders have declared a Fourth Revolution: an age of Artificial Intelligence (AI), advanced automation, and sophisticated robotics.

Every day new travel sites and apps are launched that promise to make trip planning easier. Some do and some don't. Here are two free tools optimized for smartphones that I tested and really liked: Lonely Planet's free Guides app for iOS and Android, and Destinations on Google, which makes it easy to aggregate information for your next travel adventure. The app includes more than 35 free importable guides to international and U.S. destinations, from Bangkok to London and Boston to San Francisco. I tested New York, Kyoto and Vancouver.

Until now, medicine has been a prestigious and often extremely lucrative career choice. But with intelligent machines now used to diagnose diseases, in the near future, will we need as many doctors as we have now? Are we going to see significant medical unemployment in the coming decade? Dr Saxon Smith, president of the Australian Medical Association NSW branch, said in a report late last year that the most common concerns he hears from doctors-in-training and medical students are, "what is the future of medicine?" The answers, he said, continue to elude him.

A new Federal Government report has outlined the future of Australia's workforce and revealed growing demand for professionals in STEM industries. The report by CSIRO and the Australian Computer Society, titled Tomorrow's Digitally Enabled Workforce, identified six megatrends. The trends include continued advances in automation and artificial intelligence; jobs will be more flexible and agile due to digital technology; a requirement for entrepreneurial skills; and an increase in skills and education requirements for many professions. While the report found that 44% of Australian jobs would be impacted by these changes, Andrew Johnson, CEO of the Australian Computer Society and one of the report's authors, said there are numerous opportunities for engineers. 'The intent of this report is to look at a 15- to 20-year timeframe.
