This week humankind was delivered a body blow by an artificial intelligence (AI) called AlphaGo that beat Go's world champion, Lee Sedol, so is it now time for humans to let the machines rule the world? Not just yet--while this adds to a growing list of machines that have beaten the best humans at chess, checkers and backgammon, Lee Sedol won a game back against AlphaGo, so there is still hope for us. The ancient Chinese strategy game Go has substantially more moves to consider each turn than chess. With the two players having to look several moves ahead with more possible outcomes than there are atoms in the universe before deciding what move to make. For each move in a game such as Go, the AI uses a tree search that plays out scenarios, notes which lead to the most victories, and then works back to find out the next move that will lead to the best scenario.

The head of Microsoft's Xbox has apologised after the company hosted a party for computer games developers that featured podium performances by female go-go dancers. The evening event in San Francisco was held on the same day as a Microsoft-sponsored "women in games" lunch. The dancers were dressed in short skirts and crop tops. Phil Spencer said it was "unequivocally wrong", after attendees took to social media to complain. The event took place during a week-long conference for developers creating games for Xbox.

But it could be a real threat, warn researchers at the recent World Economic Forum. Unlike today's drones, which are still controlled by human operators, autonomous weapons could potentially be programmed to select and engage targets on their own. "It was one of the concerns that we itemized last year," Toby Walsh, professor of artificial intelligence (AI) at the school of computer science and engineering at the University of New South Wales, told FoxNews.com. "Most of us believe that we don't have the ability to build ethical robots," he added. "What is especially worrying is that the various militaries around the world will be fielding robots in just a few years, and we don't think anyone will be building ethical robots."

While traveling in Western Samoa many years ago, I met a young Harvard University graduate student researching ants. He invited me on a hike into the jungles to assist with his search for the tiny insect. He told me his goal was to discover a new species of ant, in hopes it might be named after him one day. Whenever I look up at the stars at night pondering the cosmos, I think of my ant collector friend, kneeling in the jungle with a magnifying glass, scouring the earth. I think of him, because I believe in aliens--and I've often wondered if aliens are doing the same to us.

There is no meaningful sense in which there is an abstract notion of purpose. That is, purpose is something that comes from history. One of the things that might be true about computation, might be true about our world, that would be disappointing, is maybe we go through all this history and biology and civilization and so on, and at the end of the day, the answer is 42 or something. That's the end, so to speak. We got to the answer.

We hear about AI taking over our jobs. We hear about AI listening in on our conversations. We hear about AI becoming a substitute for our romantic partners. Here's what the real AI experts Guru Banavar, (IBM), Toby Walsh, (The University of New South Wales), and Roman Yampolskiy (University of Louisville), say about the subject, and why a lot of what you think you know is probably wrong. Humans 2.0: How the robot revolution is going to change how we see, feel, and talk Robots aren't going to replace us, but by working hand in hand with us they will redefine what it means to be human.

At San Francisco's first fully automated restaurant, meals appear in little glass cubbies, just 90 seconds after customers order and pay on wall-mounted iPads. It's a human-less experience – no waitstaff, no cashier, no one to get your order wrong and no one to tip. The moment before the meal appears, the see-through display screen that fronts the cubbies goes black for the few seconds when you might catch sight of the hand that feeds you. Eatsa has not yet achieved total automation. The company admits it employs a small kitchen staff, and one employee is present in the front of the house, answering questions about how to order and dodging questions about what's going on behind the wall of magic cubbies.

If data science can be used to craft a brand-new beer, why shouldn't an autonomous robot deliver the accompanying pizza? That, in fact, is exactly the premise behind a new initiative from Domino's. Australia-based Domino's Pizza Enterprises has created an autonomous delivery vehicle named Domino's Robotic Unit, or DRU, and begun limited testing on restricted streets in Queensland. The device, announced Thursday, is a four-wheeled vehicle with compartments built to keep the customer's food hot and drinks cold. A "friendly persona" aims to help customers identify and interact with it. DRU can now navigate from a starting point to its destination, selecting the best path of travel.

For decades, futurists have predicted that commercial miners would one day tap the unimaginable mineral wealth of the world's ocean floor. Soon, that subsea gold rush could finally begin: The world's first deep-sea mining robots are poised to rip into rich deposits of copper, gold, and silver 1,600 meters down at the bottom of the Bismarck Sea, near Papua New Guinea. The massive machines, which are to be tested sometime in 2016, are part of a high-stakes gamble for the Toronto-based mining company Nautilus Minerals. Nautilus's machines have been ready to go since 2012, when a dispute between the firm and the Papua New Guinean government stalled the project. What broke the impasse was the company's offer, in 2014, to provide Papua New Guinea with certain intellectual property from the mining project.
