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.

Marvin Minsky, the AI pioneer and MIT professor, died on Sunday in Boston. Dr. Minsky, an IEEE Life Fellow, made numerous seminal contributions to the fields of artificial intelligence and robotics, exploring, among other things, how a better understanding of human cognition could lead to advances in machine intelligence, and vice versa.

Everybody knows that anthropomorphic robots that try to look and act like people are creepy. There's been a bunch of research into just what it is about such androids that we don't like (watch the video below to get an idea of what we're talking about), and many researchers think that we get uncomfortable when we begin to lose the ability to confidently distinguish between what's human and what's not. This is why zombies are often placed at the very bottom of the Uncanny Valley: in many respects, they directly straddle that line, which is why they freak us out so much. The tricky part about robots, however, is that they can manifest "human-ness" in ways that are more than just physical. When robots start acting like humans, as opposed to just looking like them, things can get much more complicated.

Mark your calendars: the premiere of NOVA's "Rise of the Robots" is in less than two weeks! Loyal readers of this blog will probably recognize all of the robots and most of the people in the trailer, but it looks like NOVA--which bills itself as "the most-watched primetime science series on television"--scored some great expert commentary along with footage of DRC robots that we've never seen before.
